Gerodontology (Gerodontology)

Publisher: Gerodontology Association, Wiley

Journal description

The ultimate aim of Gerodontology is to improve the quality of life and oral health of older people. The boundaries of most conventional dental specialties must be repeatedly crossed to provide optimal dental care for older people. In addition, management of other health problems impacts on dental care and clinicians need knowledge in these numerous overlapping areas. Bringing together these diverse topics within one journal serves clinicians who are seeking to read and to publish papers across a broad spectrum of specialties. This journal provides the juxtaposition of papers from traditional specialties but which share this patient-centred interest, providing a synergy that serves progress in the subject of gerodontology.

    ABSTRACT: The aim of this study was to validate a Spanish cross-cultural adaptation of the xerostomia inventory (XI). The original English version of XI was translated into Spanish, cross-culturally adapted and field tested. The Spanish version of XI (XI-Sp) was tested with a sample of 41 patients with xerostomia. The reliability of the XI-Sp was determined through internal consistency and test-retest methods. The construct validity of XI-Sp was determined by means of correlation between XI-Sp scores and salivary flow measurements. Overall XI-Sp scores were 40.8 (SD = 10) for the first application and 40.2 (SD = 9.5) for the second. Cronbach's alpha value for the XI-Sp was 0.89 and 0.87, respectively, while interitem correlation averages were r = 0.44 and r = 0.39 for each application. Interitem correlation and corrected total was rc ≥0.30. The test-retest intraclass correlation coefficient value for the XI-Sp score was 0.59 and 0.91. Convergent validity for construct validity correlation with salivary flow showed a medium effect size (r(2) = 0.10) for the first application but did not make a statistically significant prediction for the second (r(2) = 0.7). This study provides evidence concerning the reliability of the XI-Sp, showing that it may be a useful tool for Spanish-speaking xerostomia patients for both clinical and epidemiologic research. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

    ABSTRACT: Objective To investigate the effects of wearing complete dentures on pharyngeal shape for swallowing in edentulous older people.Background In the absence of complete dentures, edentulous older people often lose the occlusal support necessary to position the mandible, which leads to an anterosuperior shift of the mandible during swallowing. This may result in pharyngeal shape changes effecting swallowing function in older people. However, the details of this phenomenon are currently unclear.Materials and methodsParticipants were 17 older edentulous volunteers. Cone-beam computed tomography imaging was performed with the participant in the seated position and wearing (i) both maxillary and mandibular dentures, (ii) maxillary dentures only and (iii) no dentures. During imaging, participants were instructed to keep their mouth closed to the mandibular position determined in advance during swallowing for each denture-wearing condition. The volume, height and average cross-sectional area of the velopharynx and oropharynx were measured, and the positions of the epiglottis and mandible were recorded.ResultsWhile the vertical height of the oral cavity and pharynx significantly decreased, the volume and average cross-sectional area of the oropharynx significantly increased when dentures were not worn (p < 0.01). The absence of dentures caused an anterosuperior shift of the mandible when swallowing and drew the epiglottis forward, resulting in expansion of the oropharynx where the tongue base forms the anterior wall.Conclusion The absence of dentures results in anatomical changes in oropharyngeal shape that may exacerbate the pharyngeal expansion caused by ageing and reduce the swallowing reserve.

    ABSTRACT: To determine the perceptions of dental care held by the residents in aged care facilities (ACFs) in New South Wales (NSW) and to compare these perceptions with clinical observations. No specific data exist relating to NSW residents' perceptions of dental care compared with a clinical examination. Planning for appropriate oral health programs in ACFs necessitate such data. Four Area Health Services of Sydney and 25 low care ACFs were selected from which representative residents were sampled who completed a survey and underwent a basic dental examination. Of the subjects (25 males, 96 females), 76.9% had never received a dental visit as entering the ACF; 14.1% suffered from dental pain; 69.4% wore dentures and of these 18.3% required assistance in cleaning. Dentures were cleaned twice/day in 54.9% of cases. Natural teeth were reported present in 71.9% of residents, and 85.1% did not require assistance in cleaning. Appropriate dental care facilities and dry mouth were most frequent problems highlighted. Clinical examinations showed that 69% were denture wearers; oral hygiene and denture hygiene were considered good in 15.7% of cases. A high level of concordance existed between self-reports and examination. Increased awareness about oral health across leadership, caregivers and residents with appropriate dental health education and dedicated space within facilities would provide a much needed improvement for addressing oral health issues of the ACF residents. This might be the right time to plan for the future challenges that will need to be met by the NSW care system. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

    ABSTRACT: To investigate cytotoxic and genotoxic effects of static magnetic field (SMF) produced by dental magnetic attachments on human gingival fibroblasts in vitro. Magnetic attachments have numerous roles in dental prosthesis fixation, but few reports evaluate possible biological effects of static magnetic field (SMF) on human gingival tissues, particular genotoxic effects. The Dyna (500-gr breakaway force) and Steco (173-gr breakaway force) dental magnetic attachments were embedded into autopolymerising acrylic resin in four different configurations each, including single and double magnets. Gingival biopsy was performed on 28 individuals during third molar extraction, and each sample was divided into two pieces for culture under SMF exposure or as a control. In total, seven test and seven control gingival fibroblast cultures were performed for each group resulting in 56 gingival fibroblast cultures. The test culture flasks were placed atop the magnet-embedded resin blocks. After cultures were terminated, mitotic index (MI) and micronucleus (MN) rates were analysed at a p = 0.05 significance level by Wilcoxon's test; intergroup differences were analysed with a Kruskal-Wallis test. There was no significant difference in intragroup or intergroup MI rates. The double Dyna (p = 0.023) and double Steco (p = 0.016) groups had statistically significant intragroup differences in the MN rates. There were no statistically significant differences in MN rates in intergroup analyses. In particular, higher magnetic fields from dental magnetic attachments might be toxic genetically to human gingival fibroblasts. However, there is need for further investigations from different aspects to detect any genotoxicity. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

    ABSTRACT: Obstructive sleep apnoea (OSA) is associated with a variety of adverse health outcomes. Continuous positive airway pressure (CPAP) is considered first-line treatment for sleep apnoea patients, but there are few studies on oral health in patients with OSA who are using CPAP. This study aimed to estimate the prevalence of oral symptoms and interest in alternative treatments such as oral appliance (OA) therapy in CPAP users. A questionnaire was used to ascertain oral health including denture use, oral symptoms at present and since the start of CPAP, and interest in OA therapy. Relevant demographic and clinical data were collected from medical records. The 744 participants who completed the questionnaire had following characteristics (mean ± standard deviation): age (55.1 ± 12.9 years); apnoea-hypopnoea index (40.9 ± 23.2/h); body mass index (27.9 ± 5.2 kg/m(2) ) and length of CPAP usage (49.1 ± 30.7 months); halitosis (30.4%); and gingival bleeding (27.5%). Nearly half (44.6%) complained of dry mouth since beginning CPAP therapy. Patients with diabetes were older (57.8 ± 11.9 vs. 54.2 ± 12.8 years), had a higher rate of denture use (28.3 vs. 19.0%), more dental clinic visits (71.4 vs. 58.7%) and more oral symptoms (50.0 vs. 38.2%) than non-diabetes patients (p < 0.05). Thirty-eight per cent of subjects were interested in OA therapy. This study exhibited that almost 40% of CPAP users had oral symptoms. In particular, OSA patients with diabetes may be at high risk of oral disease. © 2015 John Wiley & Sons A/S and The Gerodontology Association. Published by John Wiley & Sons Ltd.

    ABSTRACT: The aim of the present study was to quantify the relation between physical fitness and oral function, including tongue and lip movements. Physical fitness and oral function influence quality of life and activities of daily living in older individuals. Occlusal contact and mastication performance are associated with physical fitness, but the association between tongue and lip movements and physical fitness is unclear. Sixty-six independent community-dwelling older individuals (24 men, 42 women; mean age, 70.3 ± 5.9 years) participated in this study. Measures of physical fitness were the one-leg standing time with eyes open, the functional reach test, anteflexion, the timed up and go test, and grip strength. Measures of oral function were tongue pressure, lip pressure, tongue movement from side to side, the repetitive saliva-swallowing test (RSST), oral diadochokinesis and masticatory efficiency. Multiple regression analysis was used to quantify the relation between physical fitness and oral function. After adjustment for age, sex, BMI, exercise habits and number of remaining teeth, the tongue movement from side to side and/or oral diadochokinesis were chosen as significant factors in each physical fitness measurement. Furthermore, the lip pressure and masticatory efficiency were associated with handgrip strength. Oral function, including tongue and lip movements, was associated with physical fitness in older people in this study. Tongue dexterity as characterised by tongue movement from side to side and oral diadochokinesis particularly associated with physical fitness. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

    ABSTRACT: In this article an attempt has been made to postulate a possible link between Parkinson's disease and periodontal disease. Various systemic diseases such as cardiac disease, diabetes, renal diseases, low birth weight and Alzheimer's disease have been proposed to be linked with periodontal disease on the basis of systemic inflammation. Parkinson's disease is a chronic progressive neurodegenerative disorder with multifactorial aetiology. Until now, periodontal disease and Parkinson's disease has been linked only on the basis of poor motor and cognitive control in Parkinson's patient which leads to poor oral health maintenance. Evidence now suggests that chronic neuroinflammation is consistently associated with the pathophysiology of Parkinson's disease. Also, recently, systemic inflammation has been suggested as one of the contributing factors for neurodegeneration. Dental and medical literature especially those dealing with neurosciences were selected which highlighted the link between systemic inflammation and infection. So far there is no direct evidence implicating an effect of periodontitis in the pathogenesis of Parkinson's disease. To clarify this link, studies on population based case-control or cohort design are needed. This would be especially significant in the present era where there is paucity for preventive measures as far as a cognitive disorder such as Parkinson's disease is concerned. We cannot cure Parkinson's disease, but if in future this missing link is established, an attempt can be made to prevent it by tackling one of its possible contributors (periodontitis) for systemic inflammation by simple preventive oral hygiene measures. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

    ABSTRACT: To investigate how German dentists adhere to recommendations regarding dental treatment of patients taking antiplatelet or oral anticoagulation therapy for cardiovascular protection. Discontinuation of antiplatelet or oral anticoagulation therapy prior to dental procedures is usually not recommended because the risk of thromboembolic events is higher than that of significant procedure-related bleeding. An anonymous questionnaire regarding the handling of and experiences with patients taking aspirin (acetylsalicylic acid) or vitamin-K-antagonists (phenprocoumon) was distributed to approximately 4500 dentists attending the national German Dentists Day 2011. Of 146 dentists who completed the questionnaire 77.4% and 27.6% stated that they perform tooth extractions under continued therapy with aspirin or vitamin-K-antagonists, respectively. When asked regarding the INR or Quick values, they require for tooth extractions in patients taking oral anticoagulants 29.5% of the dentists provided values that were outside the safe range (INR ≤1.5 or ≥3.5) and 90.7% accepted values too old to be clinically reliable. For pain relief after dental procedures, 71.2% of the dentists recommended ibuprofen notwithstanding the fact that it attenuates protective effects of aspirin and 10.2% would discontinue aspirin and prescribe ibuprofen or paracetamol (acetaminophen). Despite similar recommendations the majority of dentists perform tooth extractions in patients taking aspirin but not in patients taking vitamin-K-antagonists. Moreover, a potentially unfavourable drug interaction of aspirin and ibuprofen is frequently not considered. In patients taking vitamin-K-antagonists too many dentists rely on laboratory values that are too old or outside the recommended range. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

    ABSTRACT: The objective of this study was to explore how social interactions and body image are influenced by perceived oral health among older people who live in long-term care facilities. Social interactions among frail elders in long-term care (LTC) facilities are limited, but to what extent body image and oral health influence their social relations is poorly understood. A positive body image and the perception of adequate oral health are linked to increased social contacts, as well as improved health and well-being irrespective of age. However, as frailty increases, it is unclear whether appearance and oral health priorities remain stable. Open-ended interviews were conducted with a purposefully selected group of cognitively intact, older men and women who exhibited varying degrees of frailty, social engagement and oral health conditions and lived in one of seven long-term care facilities. The interviews were analysed using a constant comparative technique, and a second interview with participants checked the trustworthiness of the analysis. Three major categories were expressed by the participants: (1) My mouth is fine; (2) It depends; and (3) Not that important. Within each category, there were several contributing and influencing factors. Social interactions among residents in LTC may be negatively impacted by poor oral health, but only if other personal and social issues are less bothersome than conditions with the mouth. © 2015 John Wiley & Sons A/S and The Gerodontology Association.

    ABSTRACT: Objective: To explore the relationship between treatment plans, complexity anticipated in delivering those plans, and the special care dental skills and settings identified as appropriate. Background: In older adults, many factors may complicate dental treatment including health and dis- ability problems. Assessment of dental treatment needs amongst care home residents provides informa- tion about clinical care required and clinical experience needed for this population. Material and methods: Analysis of dental data collected in a 2010 Welsh survey. Data analysed included treatment plan information, complexity assessment and dental expertise and settings required to deliver the treatment plans. Results: The majority of participating residents needed simple dentistry, that is examinations, oral hygiene instruction, scaling of teeth, fillings, new dentures and fluoride application. Additional time was the commonest complexity factor. A large proportion of participants required dental treatment within a domiciliary setting. A similar proportion required care within a primary care setting (typically with care from a general dental practitioner) or a special care clinic (typically with care from a dentist with special care experience). Treatment plans involving specialists were more likely to be associated with poor gen- eral health, higher levels of interventional treatment and greater complexity. Conclusion: Most treatment need in care homes is basic restorative, periodontal and preventive care. Half of this could be managed by general dentists, some on a domiciliary basis and the rest in primary care dental clinics. The commonest complexity was additional time. More complex treatments were associated with care in clinics, skills in special care dentistry and multidisciplinary care.

    ABSTRACT: Objective We developed a new scoring index for assessing the removability of denture adhesives and evaluated the removal efficiency of denture cleaners.Background Although our understanding of the importance of denture care is increasing, little is known about the effectiveness and efficiency of denture cleaners on denture adhesives. Therefore, guidelines for proper cleaning are necessary.Materials and methodsWe used five denture cleaner solutions on two cream adhesives, one powder adhesive and one cushion adhesive. After immersion in the denture cleaners for a designated time, we evaluated the area of the sample plate still covered by denture adhesive.ResultsCream adhesives were removed more completely after immersion in majority of the denture cleaners than in water. Powder adhesive was removed more quickly than cream adhesives. Cushion adhesive was not removed by immersion in either the denture cleaners or water control.Conclusion Some denture cleaners could liquefy cream adhesives more than water, but these differences were not observed in case of powder and cushion adhesives.

    ABSTRACT: Objective This study analysed all hospitalisations of persons over the age of 65 years for oral health-related conditions, over a decade, and projected future hospitalisation rates.Background The proportion of older Australians is increasing, and their oral health is improving. At the same time, there is concern about the increasing burden that hospitalisations place on government health budgets.Methods Hospitalisation data of all patients older than 65 years, admitted to hospital for an oral health-related condition in Western Australia over a decade, were analysed.ResultsOver a ten-year period, a total of 11608 people over the age of 65 were admitted to hospital, with 10% 85 years and older, 52% were men, and 0.1% were Aboriginal patients. The highest rates of hospitalisation were for those from the most disadvantaged areas. Over ten years, there was a significant annual increase in rates of hospitalisation (4.4%). Overall, most admissions were for ‘Malignant neoplasms’ (16.6%), ‘Dental caries’ (15.4%) and ‘Other disorders of the teeth and supporting structures’ (14.3%). These three conditions accounted for almost half of all admissions (46.4%). Projections indicate high future burdens of hospitalisation.Conclusions It is of concern that hospitalisations for oral health-related reasons among the oldest patients include high numbers with potentially preventable conditions such as dental caries. Projections indicate that if current trends are set to continue, hospitalisations for oral health-related conditions among Western Australians older than 65 years will place a considerable burden on the health system.

    ABSTRACT: Objective To cross-culturally adapt the oral impacts on daily performance (OIDP) and assess its reliability and validity on Chinese-speaking community dwelling elderly Singaporeans.Background There are no previous reports of valid oral health-related quality of life instruments for elderly Singaporeans or perceived conditions associated with impacts reported in OIDP among the Singaporean elders.Methods The OIDP was translated from English to Chinese and then back translated. The OIDP questionnaire along with questions related to overall quality of life and self-rated dental health was administered to 202 Chinese-speaking elderly Singaporeans by trained interviewers, and it was repeated after 1 month. Test–retest reliability was assessed using intraclass correlation coefficient; internal consistency was established using Cronbach's alpha, and construct validity using correlation coefficients with self-reported oral health-related and global quality of life measures. In addition, Kruskal–Wallis tests assessed differences in the OIDP score between different subjective health and global quality of life groups.ResultsThe median age of participants was 75 years. About 19% reported oral impacts and difficulty eating was the most prevalent oral impact. Internal consistency was good with a Cronbach's alpha of 0.75, and the intraclass correlation coefficient was 0.75 (0.67–0.81). OIDP was significantly correlated with all measures of self-reported oral health and global ratings of quality of life, with correlation coefficients ranging between 0.15 and 0.52. Groups with worse perceptions about their health and quality of life had significantly higher OIDP scores.Conclusion The OIDP showed successful reliability and validity for its use among Chinese-speaking older Singaporeans.

    ABSTRACT: Objective Candida albicans-associated denture stomatitis is the most common type of denture stomatitis seen in denture wearers. This study evaluates and compares the antifungal action of fluconazole, chlorhexidine gluconate and tea tree oil on heat-polymerised denture base resin, which has been previously contaminated with C. albicans grown in BHI broth.Material and Methods Seventy-five specimens were immersed in BHI broth previously inoculated with C. albicans and stored for 3 h at 37°C. They were divided into five groups (n = 15): G1: 2% chlorhexidine solution; G2: 100% pure pharmaceutical grade tea tree oil; G3: 65 μg/ml fluconazole solution; C1: specimens not disinfected; C2: specimens not contaminated with Candida. Each specimen was then transferred to individual tubes containing BHI broth and incubated for 24 h. Culture media turbidity was evaluated for absorbance over a period of 14 days using a microplate reader. It was observed that the lower the absorbance, the stronger the antimicrobial action. Statistical analysis was performed (two-way anova and Bonferroni test, p < 0.001).ResultsChlorhexidine and tea tree oil inhibited Candida up to the 14th day, whereas antifungal effect of fluconazole was not significant after the 7th day.Conclusion Tea tree oil and chlorhexidine gluconate are more effective than fluconazole in inhibiting C. albicans growth on heat-polymerised acrylic resin.

    ABSTRACT: Background Melanoma of the skin is characterised by a high metastatic potential, but reports of metastasis to the tongue are rare. We report a case of skin melanoma with metastasis to the lymph nodes, tongue and brain.Objectives This report highlights the clinical and histological features of oral metastatic melanoma.Case reportA 72-year-old man was seen with a nodule on the tongue. The differential diagnosis included salivary gland tumour, lymphoma and metastatic melanoma. His medical history revealed treatment for melanoma in the periumbilical region and micrometastases in the inguinal lymph nodes. An incisional biopsy was obtained and histological analysis showed the presence of a solid, epithelioid malignant tumour of monotonous appearance infiltrating the skeletal musculature. Immunohistochemistry showed reactivity of neoplastic cells to anti-HMB45, anti-melan A and anti-S100 antibodies and negativity for anti-PAN cytokeratin, confirming the diagnosis of metastatic melanoma.Conclusion The present findings highlight the importance of a complete medical evaluation of the patient by anamnesis to identify possible oral repercussions of primary diseases in other organs and/or systems.
