[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to investigate immunohistochemically the influence of cigarette smoking on the socket healing after tooth extraction in rats. Eighty-four male rats were divided into 3 groups; 2 groups were considered as experimental and the other as control. The animals in test 1 were exposed to smoking regimen before the surgery and after the surgery, but the animals in test 2 were exposed to the smoking regimen only before surgery. All animals' maxillary right central incisors were extracted and killed at the 3rd, 7th, 15th, and 28th day. The samples taken on third day after tooth extraction were stained immunohistochemically with fibronectin antibody and the other with type I collagen antibody. On the third day after tooth extraction, samples in the control group were intense stained (3) (+++); in the test 1 they were slight positive (1) (+) and in the test 2 they were moderate positive (2) (+ +). As a result of scoring type I collagen antibody, there was no statistically significant difference between the groups at seventh day, but there were statistically significant differences between the groups at the 15th and 28th day (P = 0.000 and P = 0.001, respectively). Comparison of the paired intense scores of type I collagen antibody staining according to days within each groups were not statistically significant. As a result, we have found out that the healing process of the tooth extraction socket is negatively affected by cigarette smoke.

[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to investigate the effects of systemic and topical ozone applications on alveolar bone healing following tooth extraction. One hundred and twelve male Wistar rats were divided into eight groups of 14 rats each; seven groups were experimental (A–G) and one formed the control group (K). The experimental groups were further divided into two sub-groups, with seven rats in each – sacrificed on days 14 and 28 (subgroups 1 and 2). The maxillary right central incisors were extracted under general anaesthesia following the administration of local anaesthesia. After sacrifice, semi-serial histological sections were prepared, and mineralized and trabecular bone and osteoid and osteoblast surfaces were measured. Measurements of the trabecular bone showed statistically higher values in the groups treated with systemic ozone (D2: 50.01 ± 2.12; E2: 49.03 ± 3.03; F2: 48.76 ± 2.61; G2: 50.24 ± 3.37) than in the groups that underwent topical ozone administration (A2: 46.01 ± 3.07; B2: 46.79 ± 3.09; C2: 47.07 ± 2.12; P = 0.030 (G2–A2, G2–B2, G2–C2)). Within the limitations of the current study, it may be concluded that postoperative long-term systemic ozone application can accelerate alveolar bone healing following extraction. However, additional studies are required to clarify the effects of the different ozone applications on new bone formation.

[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to evaluate the effects of estrogen deficiency on newly formed bone obtained by osteogenic periosteal distraction histomorphometrically.
Thirty-six female rabbits were divided into 2 groups. The experimental group underwent a bilateral ovariectomy and a sham operation was applied to the control group to equalize the stress of ovariectomy surgery. Four weeks postoperatively, a gradual distraction of the mandibular corpus was performed.
In the experimental group, callus formation was delayed and the new bone was less mineralized; conversely, when histomorphometric measurements were compared statistically, there were no significant differences between the ovariectomized and sham-operated subgroups in the mean extent of newly formed bone tissue.
Although osteoporosis caused by the lack of estrogen has negative effects on osteogenic periosteal distraction (OPD), these negative effects do not appear to present a contraindication to OPD.
[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to evaluate the effects of chronic pain on oral health related quality of life (oral QoL) in patients with anterior disc displacement with reduction (DDwR).
Thirty-seven patients who had disc displacement with reduction (DDwR, F/M: 23/14, median age: 29, range: 23-49) were selected. These patients had chronic pain and had not been undergoing any treatment protocols for the previous six months. Age- and gender-matched healthy subjects healthy control, F/M: 23/14, mean age: 33.0 +/- 15.7 years) were used as a control group. Data were collected by means of a clinical examination and a questionnaire about pain status which included a jaw disability checklist RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders). Pain status was scored between 0 (no pain) and 10 (poor pain status) by the patients. Oral health related quality of life (oral QoL) over the previous six months was evaluated by an oral health impact profile-14 (OHIP-14) questionnaire.
OHIP-14 score was significantly higher in patients with DDwR (median:17, min-max:6-39) than healthy controls (9, 0-18) (p = 0.000). The median duration of orofacial pain was 12 (range 7-120) months. Statistically significant correlations were observed between OHIP-14 score and the worst pain intensity in the past six months (7, 0-10) (r = 0.5 p = 0.007) and average pain intensity in the past six months (5.5, 1-10) (r = 0.4 p = 0.018). In addition, an increase in OHIP-14 score was observed in patients experiencing difficulty in smiling/laughing, cleaning their teeth or face, swallowing or talking, according to the jaw disability checklist (p = 0.042, p = 0.001, p = 0.023 and p = 0.007, respectively).
Poor oral QoL was related to chronic pain and limitations in jaw function in patients with DDwR.

[Show abstract][Hide abstract] ABSTRACT: Close proximity of the inferior alveolar nerve (IAN) to the third molar roots can result in nerve injuries during extraction of third molars. Consequently, it is necessary to determine the relationship of the nerve and roots to avoid damage to the IAN. Computed tomography scans are widely used to determine the correct relationship between the IAN and lower third molars.
The study consisted of 10 patients with 16 lower third molars in close relationship with the IAN who were divided into a study group and a control group. The patients in the study group were treated via coronectomies performed with endodontic treatments. The patients in the control group underwent coronectomies without endodontic treatment. The patients were followed up for at least 1 year.
We had to extract 7 of the roots because of the infection in 8 patients belonging to the study group, which were treated endodontically. Moreover, there were 3 cases of IAN damage because of the extraction in the study group. However, in the control group, no infection was determined and IAN damage was absent.
Coronectomy appears to be a reliable technique to protect the IAN from damage. This procedure has a low incidence of complications. Endodontic treatment does not affect the success of this method according to our results.

[Show abstract][Hide abstract] ABSTRACT: The aim of the study was to evaluate the influence of dental and periodontal treatments to the course of oral ulcers in patients with Behcet's disease (BD).
Fifty-eight consecutive BD patients with oral ulcers were studied. Twenty-nine patients were in the intervention group (F/M: 15/14, mean age: 39.6 +/- 6.9 years) and 29 (F/M: 15/14, 39.4 +/- 10.6 years) were followed with a conventional treatment approach. In addition to oral hygiene education, dental and periodontal treatments were carried out in the intervention group, whereas the control group was only given oral hygiene education. Patients were evaluated in the pre-treatment observation period (1 month), treatment period (1 month) and 6 months after treatment.
An increase in the number of new oral ulcers (4.1 +/- 3.5) was observed within 2 days during the treatment compared with 3-30 days during treatment month (2.3 +/- 1.2) (P = 0.002). However, 6 months after the treatment, the number of oral ulcers (1.9 +/- 1.5) was significantly lower compared with the pre-treatment observation (4.8 +/- 3.2) (P = 0.000) and treatment periods (6.4 +/- 2.3) in the intervention group (P = 0.05), whereas a similar oral ulcer presence was observed in the control group (2.8 +/- 2.4, 3.7 +/- 2.3 and 4.8 +/- 4.3, respectively) (P > 0.05). Dental and periodontal indices were also better in the intervention group during the 6-month follow-up.
Our results suggest that, in BD patients, dental and periodontal therapies could be associated with a flare-up of oral ulcers in the short term, but may decrease their number in longer follow-up. They also lead to a better oral health.

[Show abstract][Hide abstract] ABSTRACT: The protection of microcircular support which is essential for healing gains importance if implant surgery is considered to affect the blood flow. The aim of the study is to establish the artery territories supplying the blood into the oral mucosa in the cadavers and to demonstrate the mucosal delivery pattern and to evaluate the effects of different incision types on the healing in the patients having the implant application.
The study was planned in two stages as cadaver and clinical investigations. In cadaver investigation, all intra oral vascular territories were shown in ten specimens. The arterial structure and mucosal vascularity of the area were assessed microscopically and macroscopically. With the obtained data, the clinic results were established by making the crestal incision only for Group 1 (n = 30); both crestal and vertical releasing incisions for Group 2 (n = 30) were planned.
The results were established anatomically and clinically. In all cases, vascular territories of the mucosa in the maxilla and mandible were evaluated. In stereo microscopic assessment, although vestibule and oral mucosa had rich anastomoses, the crestal line had avascular features. There was no complication in the soft tissues of the cases, performed the vertical releasing incision during the healing period after 8-week follow-up.
The vascular richness of the oral mucosal area enables the sufficient healing in the areas of applied flap. According to the alveolar anatomical pattern and the amount of the soft tissue over it, the incisions may be applied horizontally and/or vertically.

[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to compare histomorphometrically the new bone tissue obtained using two different distraction methods, and evaluate these two methods in terms of their advantages and disadvantages. In 36 New Zealand adult male rabbits, divided into two groups, a gradual distraction was performed using a device placed on the lateral surface of the mandibular corpus. In one group osteotomy was not performed and osteogenesis by periosteal distraction (OPD) only was used. In the other group, conventional distraction osteogenesis (DO) was performed. After a 7-day latent phase, the same distraction protocol was applied to both groups. Each group of rabbits was further divided into three sub-groups killed on the 15th, 30th and 60th days of the consolidation period, and histological analysis was performed. The mean extent of newly formed bone tissue was 14.4 mm2 in the OPD groups and 25.4 mm2 in the DO groups. When compared statistically, there were significant differences between all the DO and OPD sub-groups. The newly formed bone tissue obtained by OPD was rich in interstitial fatty tissue. These results indicate that bone tissue newly formed by OPD is not suitable for occlusal forces.

[Show abstract][Hide abstract] ABSTRACT: This study was undertaken with a view to determine the acceptance and treatment possibilities of midazolam, depending upon its oral and rectal application for pediatric patients requiring an oral surgery procedure (tooth extraction) and having a pretreatment behavioral score of 1 or 2 according to the Frankl Scale. Oral (0.5 mg/kg) and rectal (0.35 mg/kg) midazolam was compared in view of acceptance of the mode of treatment and local anesthesia, level of amnesia, and adverse effects. Although oral or rectal midazolam application has similar characteristics in respect to ease of working, the oral midazolam application should generally be preferred because it is more easily accepted by pediatric patients.

[Show abstract][Hide abstract] ABSTRACT: Dehiscence-type bony defects may occur after implant application because of microbial action as well as of biomechanical and occlusal overload. The aim of the treatment of a periimplant defect is to arrest the progression of the bone loss and to achieve a maintainable site for the implant. In these situations, barrier membranes and bone graft materials can be used to achieve complete bone healing around dental implants. Bone regeneration is possible in a periimplant bony defect of a functioning implant if the proper surgical technique is utilized and the etiologic cause is eradicated. This study presents the surgical coverage of a periimplant bony defect around an implant that was inserted 7 years ago. The surgical correction was made using a barrier membrane in conjunction with bone graft materials. A follow-up of 6 months seemed to reveal radiographic bone regeneration.
