Acupuncture for anxiety in dental patients: Systematic review and meta-analysis
Abstract
Introduction: Dental anxiety affects an estimated 4% to 30% of the adult population in countries world-wide. The objective of this study was to conduct the first systematic review and meta-analysis of randomised controlled trials of acupuncture to reduce anxiety in dental patients. Methods: Online databases (OVID/AMED, Cochrane Library, CINAHL, OVID/Medline, EMBASE, PROSPERO, PsycINFO, PubMED, as well as databases in Chinese, Portuguese, Spanish and German) were searched up to July 2017 for eligible trials involving dental patients receiving an acupuncture intervention with measured anxiety scores. Comparators were placebo, usual care, or another dental anxiety intervention. Included studies were assessed using the Cochrane Risk of Bias Tool. Results: From 129 trials identified as potentially eligible, six trials with 800 patients were included in this review. Two trials (combined n = 249) were rated as moderate-to-high or high quality, both used auricular acupuncture, and were the only two trials to report continuous post-intervention anxiety scores, both using the (80-point) State-Trait Anxiety Inventory (STAI). A meta-analysis comparing acupuncture with no-intervention controls found a statistically significant and clinically relevant reduction in anxiety of −8.43, 95% CI (−11.90, −5.00). A meta-analysis comparing acupuncture to placebo/sham acupuncture found a clinically irrelevant and non-significant reduction of −1.54, 95% CI (−4.73, 1.64), a contrast that might be explained by context effects. Conclusions: There is limited evidence from two good quality trials that auricular acupuncture can achieve a significant and clinically meaningful reduction of anxiety in dental patients. There is no conclusive effect of acupuncture when compared with a sham/placebo control.
... It has been shown to provide emotional support and reduce anxiety, improving patients' overall comfort and experience [25]. The placebo effect, which happens when patients believe the treatment is working, can significantly intensify the psychological benefits of acupuncture [26]. ...
... provided ample evidence that supported the effectiveness of acupuncture as an intervention to improve major depressive disorders in pregnancy [20]. In Allan et al.'s meta-analysis, the comparison of acupuncture with a no-intervention control group exhibited significant clinical mitigation in the anxiety level of dental patients, though an insignificant drop was observed when acupuncture was compared with a sham/placebo control [21]. A meta-analysis compared acupuncture and nonacupuncture interventions in the treatment of anxiety, but it did not report any significant difference between A point estimate (the size of the square corresponds to its weight), Combined overall effect of treatment. ...
... Acupuncture has been demonstrated to be a very effective way of controlling anxiety, particularly mental anxiety, 29 and general anxiety. 30 The anxiety involved in undergoing IVF-ET is very similar in nature to mental anxiety; thus, it is expected that this could explain the mechanism of acupuncture's improving the success rate when used with IVF-ET. ...
Background: Assisted reproductive technology (ART) is the routine treatment for infertility. The success rate for individual sessions is generally not high, and many patients need to undergo several cycles. To increase their chances of success, many patients turn to acupuncture to complement ART. Many clinical trials of acupuncture helping in vitro fertilization (IVF) have focused only on IVF-embryo transfer (ET). In some difficult cases, when even IVF cannot be offered, acupuncture and Chinese herbs can improve the patients' conditions to reach a level at which ART can be successful. Cases: Six cases showed how acupuncture and Traditional Chinese Medicine (TCM), using Chinese herbs, can make IVF possible in difficult cases and how they can also help prevent miscarriage afterward. The cases included patients with amenorrhea, sperm disorders, polycystic ovary syndrome, diminished ovarian reserve (DOR), tubal blockage, premenopause, and premature ovarian insufficiency. Results: Acupuncture and Chinese herbs worked together to help make ART possible or easier. The ART used for these patients included intrauterine insemination, IVF, IVF with a donor egg, and introcytoplasmic sperm injection. In 3 cases, IVF was not initially successful but was successful after TCM treatment. Conclusions: These 6 cases demonstrated the positive effect of a combined approach, using acupuncture and herbs to reduce DOR and regulate hormonal disorders, creating sustainable environments for conceiving and maintaining pregnancy, thus, translating into clinical success. Clinical observation of these cases sheds new light on designing future clinical trials and practice of TCM for practitioners who provide infertility treatments.
Dental anxiety causes people to postpone or refuse to go to the dentist, which further negatively impacts their quality of life and public health. Previous research has shown that mindfulness is inversely related to anxiety. However, little is known about the relationship between mindfulness and dental anxiety. The current research aimed to explore the relationship between mindfulness and dental anxiety and investigate the mediating role of rational thinking. Two studies were conducted. In study one, 206 Chinese participants completed questionnaires measuring trait mindfulness and dental anxiety (state, responding to a dental treatment scenario). In study two, 394 participants completed questionnaires measuring trait mindfulness, dental anxiety (trait), and rational thinking. The results for both studies showed that mindfulness is negatively correlated with dental anxiety. In study 1, each facet of mindfulness except Non-judging was negatively correlated with dental anxiety with Acting with Awareness having the strongest correlation, while in study 2, only Acting with Awareness was significantly negatively correlated with dental anxiety. Furthermore, rational thinking mediated the effect of mindfulness on dental anxiety. In conclusion, mindfulness is negatively related to both state and trait dental anxiety, and rational thinking mediates the relationship between mindfulness and dental anxiety. Implications of these findings are discussed.
Purpose
To evaluate the methodological quality and summarize evidence of important outcomes of systematic reviews (SRs)/Meta analyses (MAs) of acupuncture for anxiety.
Methods
We conducted a comprehensive literature search for SRs/MAs in PubMed, EMBASE, Cochrane library, Chinese Biomedical Databases (CBM), Wanfang database and China National Knowledge Infrastructure (CNKI) until November 30, 2018. Three reviewers independently extracted data and assessed the methodological quality of the reviews according to the Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2), the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used to rate the quality of evidence. In the pre-experiment, we used the intra-class correlation coefficient (ICC) to assess reviewer agreement, the ICC value for overall score was 0.978.
Results
Ten reviews were included. The assessment results of AMSTAR-2 showed that the methodological quality of all included studies was critically low. The lowest score were item “provide a list of excluded studies and justify the exclusions” and item “report sources of funding for the included studies”, none of studies provided information about the above two items, followed by the “providing a priori design” item with only two (20%) studies conforming to this item. For GRADE, of the 7 outcomes, high quality evidence was provided in only 1 (14.3%), moderate in 2 (28.6.7%), and low in 4 (57.1%).
Conclusion
Although most of the included reviews indicated that acupuncture group was more effective than control group in the treatment of anxiety, more importantly, the methodological quality of the included reviews and the quality of evidence were low. More high-quality evidence is needed to determine whether acupuncture is more effective than other treatments.
Dental anxiety and phobia result in avoidance of dental care. It is a frequently encountered problem in dental offices. Formulating acceptable evidence-based therapies for such patients is essential, or else they can be a considerable source of stress for the dentist. These patients need to be identified at the earliest opportunity and their concerns addressed. The initial interaction between the dentist and the patient can reveal the presence of anxiety, fear, and phobia. In such situations, subjective evaluation by interviews and self-reporting on fear and anxiety scales and objective assessment of blood pressure, pulse rate, pulse oximetry, finger temperature, and galvanic skin response can greatly enhance the diagnosis and enable categorization of these individuals as mildly, moderately, or highly anxious or dental phobics. Broadly, dental anxiety can be managed by psychotherapeutic interventions, pharmacological interventions, or a combination of both, depending on the level of dental anxiety, patient characteristics, and clinical situations. Psychotherapeutic interventions are either behaviorally or cognitively oriented. Pharmacologically, these patients can be managed using either sedation or general anesthesia. Behavior-modification therapies aim to change unacceptable behaviors through learning, and involve muscle relaxation and relaxation breathing, along with guided imagery and physiological monitoring using biofeedback, hypnosis, acupuncture, distraction, positive reinforcement, stop-signaling, and exposure-based treatments, such as systematic desensitization, “tell-show-do”, and modeling. Cognitive strategies aim to alter and restructure the content of negative cognitions and enhance control over the negative thoughts. Cognitive behavior therapy is a combination of behavior therapy and cognitive therapy, and is currently the most accepted and successful psychological treatment for anxiety and phobia. In certain situations, where the patient is not able to respond to and cooperate well with psychotherapeutic interventions, is not willing to undergo these types of treatment, or is considered dental-phobic, pharmacological therapies such as sedation or general anesthesia should be sought.
The current literature suggests that low-level laser stimulation of the PC 6 acupuncture points may prevent gagging. This study aimed to determine if low-level laser therapy (LLLT) can reduce the gag reflex in children undergoing intraoral maxillary radiography. This randomized, controlled, double-blind clinical trial was conducted with 25 children with moderate-to-very severe gag reflexes who required bilateral periapical radiographic examination of the maxillary molar region. Children's anxiety levels were initially evaluated using Corah's Dental Anxiety Scale (DAS) to identify any possible relationship between gagging and anxiety. A control radiograph was taken of one randomly selected side in each patient after simulated laser application so that the patient was blinded to the experimental conditions (control group). Laser stimulation was then performed for the experimental side. A laser probe was placed on the Pericardium 6 (PC 6) acupuncture point on each wrist, and laser energy was delivered for 14 s (300 mW, energy density 4 J/cm(2)) at a distance of 1 cm from the target tissue. Following laser stimulation, the experimental radiograph was taken (experimental group). Gagging responses were measured using the Gagging Severity Criteria for each group. Data were analyzed using Spearman's rho correlations and Mann-Whitney U tests. Both mean and median gagging scores were higher in the control group than in the experimental group. Patients who were unable to tolerate the intraoral control radiography were able to tolerate the procedure after LLLT. Differences between gagging scores of the control and experimental groups were statistically significant (P = .000). There was no significant correlation between gagging severity and anxiety score (P > .05). A negative correlation was found between age and gagging score in the control group (P ˂ .05). Within the limitations of this study, LLLT of the PC 6 acupuncture points appears to be a useful technique for controlling the gag reflex in children during maxillary radiography.
A group of adults can be identified with chronic non-responding anxiety symptoms who have repeatedly accessed treatments through their GP, such as cognitive behaviour therapy, bibliotherapy and medication, but with no effect. These patients make heavy use of health service resources with no beneficial outcome. This study aims to test the effect of an acupuncture formula of three specific acupuncture points, suggested in a previous pilot study.
40 participants from a psychiatry waiting list were randomised into one of two groups: group 1 (n=25) received 10 weeks of acupuncture at PC6, HT7 and LR3, and group 2 was a waiting list control group. The waiting list group (n=15) then received acupuncture. Both groups were followed up for 10 weeks after treatment. The outcome measure was the State and Trait Anxiety Inventory.
36 patients completed the study, with two dropouts in each group. State anxiety scores in the acupuncture group decreased from 57.7 (SD 13.1) to 38.8 (12.0); scores in the waiting list control group decreased from 61.5 (11.6) to 60.6 (11.7). The difference was highly significant (p<0.0001). Similar changes were seen for trait anxiety scores. The control group showed similar statistically significant improvements when they received acupuncture. The improvements were maintained after 10 weeks of follow-up in each group.
Acupuncture is a promising intervention for patients with chronic anxiety symptoms that have proven resistant to other forms of treatment.

AbstRAct This article reviews the possible role and application of acupuncture in dentistry. The use of acupuncture in Traditional Chinese Medicine (TCM) has a long history and for the past forty years, many studies have been conducted to understand the scientific basis behind its therapeutic effects in Western medicine. The possible application of acupuncture in the dental field like managing post-operative pain, orofacial pain, xerostomia, Bell's palsy and dental anxiety will be discussed in detail. The inherent challenges in conducting clinical trials in acupuncture using the evidence-based medicine model will also be covered. It is envisioned that acupuncture may play a promising role in complementing conventional treatment in certain dental conditions and more studies with improved methodology should be carried out to verify its application.
BACKGROUND: Meta-analysis is a statistical method for combining the results of primary studies. It is often used in systematic reviews and is increasingly a method and topic that appears in student dissertations. MetaLight is a freely available software application that runs simple meta-analyses and contains specific functionality to facilitate the teaching and learning of meta-analysis. While there are many courses and resources for meta-analysis available and numerous software applications to run meta-analyses, there are few pieces of software which are aimed specifically at helping those teaching and learning meta-analysis. Valuable teaching time can be spent learning the mechanics of a new software application, rather than on the principles and practices of meta-analysis. FINDINGS: We discuss ways in which the MetaLight tool can be used to present some of the main issues involved in undertaking and interpreting a meta-analysis. CONCLUSIONS: While there are many software tools available for conducting meta-analysis, in the context of a teaching programme such software can require expenditure both in terms of money and in terms of the time it takes to learn how to use it. MetaLight was developed specifically as a tool to facilitate the teaching and learning of meta-analysis and we have presented here some of the ways it might be used in a training situation.

There have been six randomized controlled trials of psychological therapy with generalized anxiety disorder (GAD) using DSM-III-R and DSM-IV. All have used the Trait version of the Spielberger State-Trait Anxiety Inventory (STAI-T) as one of several outcome measures. Each study, however, employed different methods of calculating the clinical significance of outcomes making it difficult to reach a balanced appraisal of the efficacy of psychological treatment.
Raw data on STAI-T scores at pre-, post- and follow-up were obtained for each of the six studies (total N = 404). Jacobson methodology for defining clinically significant change (criterion c, reliable change index = 8, cut-off point = 46) was used to allocate each patient to one of four outcomes: worse, unchanged, improved and recovered. The proportion of patients in each category was calculated for treatment conditions in each study and also for aggregate data across types of treatment.
A recovery rate of 40% was found for the sample as a whole with 12 of the 20 treatment conditions obtaining very modest recovery rates of 30% or less. Two treatment approaches--individual cognitive behavioural therapy and applied relaxation--do relatively well with overall recovery rates at 6-month follow-up of 50-60%.
Jacobson methodology, in distinguishing between improvement and recovery on a standardized measure of general vulnerability to anxiety, provides a stringent but clinically more meaningful evaluation of the efficacy of psychological therapies with GAD than has been available hitherto. Systematic focus on either excessive worry or physiological arousal gives worthwhile results.
Anxiety related to dental treatment is a common phenomenon that has a significant impact on the provision of appropriate dental care. The aim of this case series was to examine the effect of acupuncture given prior to dental treatment on the level of anxiety.
Eight dentists submitted 21 case reports regarding the treatment of dental anxiety. The level of anxiety was assessed by the Beck Anxiety Inventory (BAI). Only patients with moderate to severe anxiety (BAI score > or =16) were included. The remaining 20 patients, 16 women and 4 men, with a mean age of 40.3 years, had a median BAI score of 26.5 at baseline. The BAI score was assessed before and after the acupuncture treatment. All patients received acupuncture treatment for 5 min prior to the planned dental treatment using the points GV20 and EX6.
There was a significant reduction in median value of BAI scores after treatment with acupuncture (26.5 reduced to 11.5; p<0.01), and it was possible to carry out the planned dental treatment in all 20 cases after acupuncture treatment. Previously this had only been possible in six cases.
Acupuncture prior to dental treatment has a beneficial effect on the level of anxiety in patients with dental anxiety and may offer a simple and inexpensive method of treatment. However, the present results need to be tested in a larger randomised clinical trial in order to evaluate the effectiveness of the acupuncture treatment in patients with dental anxiety.
A small number of fully trained Chinese doctors practise Traditional Chinese Medicine (TCM) in western cities. Use of these services by British citizens is extremely limited, mostly due to lack of any knowledge on the effectiveness of acupuncture or exposure to complementary medicine in this country. Common situations where British patients seek the help of TCM are when medical therapy has failed; in relapsing chronic diseases like asthma, rheumatoid arthritis; and in pain management (mostly headache, migraine and back pain). Patients often appreciate that only limited interventions are available for treatment of these conditions in western medicine. At least one in 10 UK specialist physicians are actively involved in complementary and alternative medicine treatments.(1) A large number of westerners offer acupuncture therapy but lack basic medical training. It is likely that people are reluctant to use these services largely because of hygiene and safety reasons. Moreover, it has been demonstrated that the serious side effects reported are five times more frequent when treatments are provided by non-medically trained therapists compared with professionally registered health care providers.(2).
Researchers examining the efficacy of medical procedures make assumptions about the nature of placebo. From these assumptions they select the sham interventions to be used in their trials. However, placebo is not well defined. A number of definitions are contradictory and sometimes misleading. This leads to problems in sham-controlled studies of medical procedures and difficulties interpreting their results. The author explores some of the contradictory definitions of placebo and assumptions and consequences of these. Principal among these is the assumption that the placebo is inert when it is not, which introduces bias against the tested medical procedures and devices. To illustrate the problem, the author examines the use of sham procedures in clinical trials of the medical procedures surgery and acupuncture in which the sham was assumed to be inert but was not. Trials of surgery and acupuncture should be re-examined in light of this.
Acupuncture is a technique which has originated in China, in which different
health issues are treated by inserting specially designed needles at various
points on the body - acupuncture points. Acupuncture stimulates the nervous
system and alters the perception and processing of pain signals and also
releases natural painkillers. These painkillers (endorphins and serotonin) are
present in the nervous system. These points serve as a tunnel to deeper
circulating channels and stimulation of these points activates the body’s
natural healing ability. The most common use of acupuncture is in the
management of pain, for which a number of studies have shown it to be
effective, particularly in the treatment of temporomandibular pain. It is
intended that acupuncture may play a promising role in certain dental
conditions like temporomandibular joint (TMJ) dysfunction, facial pain,
decreasing the level of anxiety and reducing gag reflex. Aim of this article was
to review acupuncture techniques and related articles in the literature that
have focused on its applications in preventing gag reflex and TMJ pain.
Dental anxiety and specific phobia of dental procedures are prevalent conditions that can result in substantial distress and oral health impairment. This paper critically reviews 22 randomized treatment trials aimed at reducing dental anxiety and avoidance in adults, published in peer-reviewed journals between 1974 and 2012. The following treatment techniques are reviewed: various forms of cognitive-behavioral therapy (CBT), relaxation training, benzodiazepine premedication, music distraction, hypnotherapy, acupuncture, nitrous oxide sedation, and the use of lavender oil scent. CBT delivered in a variety of formats, including one-session treatment, has the most evidence for its efficacy. Cognitive techniques, relaxation, and techniques to increase patients' sense of control over dental care are also efficacious but perform best when combined with repeated, graduated exposure. Other interventions require further study in randomized trials before conclusions about their efficacy are warranted. Limitations of the extant outcome research and implications for future treatment and research are discussed.
Abstract This study determined if any acupuncture point (acupoint) known for its calming effects also aided hypnotic induction. Hypnosis was offered to 108 patients requiring minor surgical or dental procedures. All had a history of panic attacks and surgical or dental phobias that complicated or prevented treatment. Unpleasant intruding thoughts of imminent invasive treatments handicapped their ability to accept hypnotic induction; however, acupuncture therapy was proposed to the consenting patient to facilitate hypnotic induction and augment its effects. Each patient received one selected acupoint for acupuncture therapy. Of the 6 acupoints used (LI 4, H 7, SP 6, P 6, GV 24, and Ext-hn-21), GV 24 was best at enhancing hypnotic induction whereas LI 4 produced the best muscular relaxation and P 6 for reducing tension.
The aim was to investigate the efficacy of behavioural interventions as treatment of dental anxiety/phobia in adults, by conducting a systematic review of randomized controlled trials (RCTs). The inclusion criteria were defined according to the Patients, Interventions, Controls, Outcome (PICO) methodology. The study samples had documented dental anxiety, measured using validated scales [the Dental Anxiety Scale (DAS) or the Dental Fear Survey (DFS)], or fulfilled the psychiatric criteria for dental phobia. Behavioural interventions included were based on cognitive behavioural therapy (CBT)/behavioural therapy (BT), and control conditions were defined as information, sedation, general anaesthesia, and placebo/no treatment. The outcome variables were level of dental anxiety, acceptance of conventional dental treatment, dental treatability ratings, quality of life and oral health-related quality of life, and complications. This systematic review identified 10 RCT publications. Cognitive behavioural therapy/behavioural therapy resulted in a significant reduction in dental anxiety, as measured using the DAS (mean difference = -2.7), but the results were based on low quality of evidence. There was also some support that CBT/BT improves the patients' acceptance of dental treatment more than general anaesthesia does (low quality of evidence). Thus, there is evidence that behavioural interventions can help adults with dental anxiety/phobia; however, it is clear that more well-designed studies on the subject are needed.
Objectives:
The aim of this study was to investigate the effect of ear-press needle acupuncture on Yintang point for preoperative anxiety.
Design:
This was a prospective, randomized, single-blind, controlled study.
Settings/location:
The study setting was the Department of Anesthesiology in Ankara Training and Research Hospital of Ministry of Health, Ankara, Turkey.
Subjects:
The study comprised 52 adult surgical patients.
Interventions:
A single, 20-minute session of single-point acupuncture was applied on Yintang (acupuncture group) or sham point (sham acupuncture group).
Outcome measures:
The efficacy of acupuncture was evaluated by means of the changes in bispectral index (BIS) and STAI (State-Trait Anxiety Index).
Results:
BIS values in the acupuncture group were significantly lower than in the sham group in all time intervals (p<0.0042). BIS values were lower than baseline in the study group during the entire study period (p<0.0004) while no such effect has been observed in the sham group (p>0.0004). Mean values of state anxiety (STAI-S) decreased after acupuncture in the study group (p=0,018), while no change was observed in trait anxiety (STAI-T) (p=0.156). Patients of the sham group showed no change in both parameters (p=0.387 and p=0,116).
Conclusions:
Ear-press needle acupuncture on Yintang point reduces preoperative anxiety in adult surgical patients.
Objectives:
The objective of this study was to analyse whether auricular acupuncture, acupuncture at the outer ear, could reduce state anxiety before dental treatment.
Methods:
This prospective, randomised patient-blinded study with 182 patients compared anxiety before dental treatment following auricular acupuncture at the relaxation-, tranquillizer- and master cerebral points (auricular acupuncture group) versus acupuncture at sham points (finger-, shoulder- and tonsil points; sham group) and a non-intervention control group. Anxiety was assessed using the Spielberger State Trait Anxiety Inventory (German version) before auricular acupuncture and 20 min thereafter, immediately before dental treatment.
Results:
Auricular acupuncture reduced state anxiety score more effectively from 54.7 ± 10.8 to 46.9 ± 10.4 (mean ± SD) than sham acupuncture from 51.9 ± 10.2 to 48.4 ± 10.0. In contrast, state anxiety in the control group increased from 51.0 ± 11.7 to 54.0 ± 11.6 (mean increase +3.0; CI +4.7 to +1.2). The decrease in state anxiety in both intervention groups was statistically significant (p < 0.001) when compared to the non-intervention control group. After correcting for group differences in baseline state anxiety, the reduction in anxiety was -7.3 score points (CI -9.0 to -5.6) in the auricular acupuncture group and -3.7 score points (CI -5.4 to -1.9) in the sham group (p = 0.008).
Conclusion:
Auricular acupuncture, a minimally invasive method, effectively reduces state anxiety before dental treatment.
Clinical relevance:
Auricular acupuncture could be an option for patients scheduled for dental treatment, who experience an uncomfortable degree of anxiety and request an acute intervention for their anxiety.
Noninvasive methods advocated by some clinicians are not very successful in dealing with patient gagging, while sedation approaches run the risk of the patient aspirating foreign bodies. The P-6 Neikuan acupuncture point, located on the wrist, has been used in the Far East for thousands of years for its anti-nausea and anti-anxiety properties. In the West, it is the acupuncture point most studied. Only recently has interest been shown in the P-6 point for its possible anti-gagging effect. The anti-gagging effect of P-6 stimulation is documented in this article. The P-6 point has remarkable anti-gagging effects if stimulation is applied correctly. Clinicians may apply thumb pressure at the P-6 point to achieve some effect, although this is not as effective as acupuncture. Nevertheless, a substantial percentage of gagging patients would be able to go through dental procedures without gagging when the P-6 point is stimulated.
Implications:
Ear acupuncture can decrease preoperative anxiety in adults undergoing outpatient surgery.
Auricular acupuncture can be an effective treatment for acute anxiety, but there is a lack of direct comparisons of acupuncture to proven standard drug treatments. In this study we compared the efficacy of auricular acupuncture with intranasal midazolam, placebo acupuncture, and no treatment for reducing dental anxiety. Patients having dental extractions (n = 67) were randomized to (i) auricular acupuncture, (ii) placebo acupuncture, and (iii) intranasal midazolam and compared with a no treatment group. Anxiety was assessed before the interventions, at 30 min, and after the dental extraction. Physiological variables were assessed continuously. With the no treatment group as control, the auricular acupuncture group, and the midazolam group were significantly less anxious at 30 min as compared with patients in the placebo acupuncture group (Spielberger Stait-Trait Anxiety Inventory X1, P = 0.012 and <0.001, respectively). In addition, patient compliance assessed by the dentist was significantly improved if auricular acupuncture or application of intranasal midazolam had been performed (P = 0.032 and 0.049, respectively). In conclusion, both, auricular acupuncture and intranasal midazolam were similarly effective for the treatment of dental anxiety.
The data presented in this article was collected after reviewing clinical findings gathered from using various anxiety control methods on apprehensive patients. We examined clinical applications of the eye movement (EM) component of Eye Movement Desensitization (EMD) on fearful dental patients who have histories of traumatic dental experiences. We also used Bi-Digital O-Ring Test (BDORT) to select the proper dosage of sedative to minimize the adverse side effects. For patients who did not respond well to EM, we used BDORT to select the proper sedative medication and its dosage. In certain difficult cases, we supplemented these techniques with acupuncture to augment the sedative effects. Findings were based on the clinical impressions and assessments of both the patients and the operating team. Results showed that EM, although effective in enabling patients to undergo non-invasive dental procedures such as clinical examination and simple prophylaxis, had only limited beneficial effect with invasive procedures such as extraction, drilling, and injections, etc. We also found that BDORT greatly reduced adverse side effects of sedatives such as hypertension, hypotension, hypoxia, tachycardia, bradycardia, nausea, and vomiting. For most apprehensive patients, we found that EMD and acupuncture combined with BDORT predetermined dosage for the submucosal sedation enabled these patients to undergo the complete dental treatment. The authors try to explain the mechanism of BDORT and EM in terms of visual awareness (or consciousness) and preferred patterns, where neurons in the brain respond to the actions and/or direction of movement. The authors believe that BDORT and EM could have better results if the persons performing BDORT have visual awareness and are focused on the task; whereas in EM, the patient's eye on the therapist's hand movements. A more focused approach via visual pathway will result in more favorable results in EM. Likewise, performing BDORT absentmindedly could lead to false results if visual awareness (or consciousness) is absent. "Preferred pattern" will arouse neurons in the brain to cause conscientiousness, and performing BDORT with 'open eyes' arouse the necessary visual awareness that is necessary for the successful performance of BDORT tasks.
