Candida-associated denture stomatitis in type 2 diabetes mellitus.

OBJECTIVE: To describe the clinical appearance of Candida-associated denture stomatitis (DS) in subjects with type 2 diabetes (T2DM). The relationships between the types of DS, oral complaints and associated conditions were assessed in terms of glycemic control as determined by glycated hemoglobin (HbA1c) measurements. MATERIALS AND METHODS: Demographic and clinical data were obtained from questionnaires and oral examinations of 110 edentulous patients with T2DM and 50 control subjects. RESULTS: Type II DS commonly occurred in diabetics (57.3% vs 30%; p=0.002) together with DS related oral complaints (60.9% vs 24%; p<0.001) compared with controls. Burning sensation of the mouth (BS) was the most common complaint. Dryness of the oral mucosa (DOM) (50.9% vs 6%; p<0.001), angular cheilitis (26.4% vs 8%; p=0.01) and glossitis (27.3% vs 6%; p=0.003) occurred more frequently in diabetics. Oral complaints and associated conditions of DS coincided with elevated HbA1c levels (p<0.001). Diabetics with extensive type of inflammation had higher HbA1c levels than type I/III DS subjects (p<0.001). CONCLUSIONS: Diffuse type of inflammation was associated with T2DM. BS and DOM were the most common oral complaints. Inadequately controlled diabetes with Candida-associated DS was linked to a high incidence of an extensive type of inflammation, oral complaints and associated conditions.

Restorative caries therapy in nursing home residents using composite resins and compomers without a rubber dam.

OBJECTIVE: This study was designed to investigate the prognosis of restorative caries therapy applied in nursing home residents. METHOD AND MATERIALS: In 25 consecutive patients a total of 42 restorations were placed, 23 of composite resin (APX/SE Bond) and 19 of compomer (Dyract). The working conditions, such as patient cooperation, quantity of saliva, location of cavity margins, cavity size, and gingival inflammation, were evaluated prior to treatment. The restorations were evaluated qualitatively at baseline, after 6 months, and after 12 months. RESULTS: At 12 months, all examined restorations were clinically acceptable (6 patients had died). There was no significant difference between the quality of the restorations in composite resin and compomer. The plaque scores increased significantly during the study period. CONCLUSIONS: The study showed that, within the limitation of a short-term follow-up, restorative caries therapy using composite resin or compomer was successful in nursing home residents although rubber dam was not used.

Indications for removable partial dentures: a literature review.

PURPOSE: The purpose of this report was to evaluate indications for the use of removable partial dentures based on a comprehensive literature review. MATERIALS AND METHODS: Using a model similar to a Delphi process, the literature relating to the indications and contraindications for the prescription of removable partial dentures was discussed by seven experienced educators in a 2.5-day workshop. RESULTS: Evidence for indications and contraindications for the prescription of removable partial dentures is not clearly stated in the literature; however, some basic principles are defined. There appears to be a trend in favor of the use of the shortened dental arch concept or implant-supported restorations instead of conventional removable partial dentures, given the evidence that the long-term use of removable dentures is associated with increased risks of caries and periodontitis and low patient acceptance. The presence of sound abutment teeth appears to encourage the use of removable partial dentures, as the fixed partial denture alternative requires sacrifice of healthy hard tissues. When economic factors influence the decision-making process, removable partial dentures are often chosen. CONCLUSION: While evidence-based indications and contraindications for prescribing removable partial dentures are still lacking, major underlying principles for clinical decision making are identified.

The advantages of occupational therapy in oral hygiene measures for institutionalised elderly adults.

OBJECTIVE: To investigate a new method in teaching and supervising tooth and denture brushing activities by employing occupational therapy techniques. MATERIALS AND METHODS: Sixty-one residents, 44 women and 17 men, with an average age of 85.7 +/- 6.6 years (range 72-97 years) living in a Long-Term Care home (LTC) in Geneva were enrolled in a randomised controlled trial. They were divided at random into experimental (EG) and control groups (CG) with matched age and sex distribution. Two subjects passed away during the 3-month experimental period. Following medical history, plaque scores and tooth brushing habits were evaluated within the context of a comprehensive clinical assessment. Furthermore, a Mini Mental State and a vision test were taken. Based on the results of these health assessments both the EG and the CG were divided into an 'assisted' (IA) and an 'independent' (II) subgroup. In the EG, tooth brushing was initially taught and in the IA monitored and re-educated once a week by an occupational therapist. In contrast, the CG-IA group received a weekly placebo activity such as manicure by the same person. RESULTS: From the individual movements taught and monitored by the occupational therapist, opening a tube of toothpaste (n.s.) and denture brushing (p < 0.05) were performed more independently after 3 months. Both the occupational therapy and the placebo activity led to a significant improvement in oral (p < 0.01 and 0.05) and in denture hygiene (p < 0.001 and 0.05). From all participants, the EG-IA subgroup presented the most significant amelioration in plaque (p < 0.01) and denture hygiene scores (p < 0.001). This group consisted mostly of subjects with an impaired cognitive state. CONCLUSIONS: Despite the marked placebo effect, the results indicate that occupational therapy is particularly useful to improve the oral and denture hygiene in dependent and cognitively impaired LTC residents and may promote their autonomy in the execution of activities of daily life such as denture brushing.

Caries and periodontal disease of the elderly in Pomerania, Germany: results of the Study of Health in Pomerania.

OBJECTIVE: The aim of this study was to describe the oral health status of older adults living in northeastern Germany. MATERIALS AND METHODS: Representative samples of adults aged 60 years or older were examined as part of Study of the Health in Pomerania, a cross-sectional, population-based study. Data on 1446 subjects aged 60-79 years were evaluated for coronal caries using the decayed/missing/filled teeth (DMFT) index, root caries using the root caries index (RCI), calculus, plaque, bleeding on probing, pocket depth and attachment loss. RESULTS: The prevalence of edentulousness varied from 16% in the 60-65-year-old group to 30% in the 75-79-year-old group, whereas the median number of remaining natural teeth per subject varied from 14 in the youngest age group (60-65 years) to one in the oldest (75-79 years). Among subjects aged 60-69 years, a quarter (26%) of the teeth examined had coronal restoration against 17% in the oldest age group (70-79 years). Coronal caries was found in 2% of the teeth in both age groups. Among teeth with gingival recession, 6% had fillings on root surfaces and 2% had root caries, irrespective of age. In all, 11% of the subjects had at least one untreated coronal lesion and 27% had at least one untreated root caries lesion. Plaque score, calculus score and bleeding on probing were higher in the oldest age group (70-79 years). The prevalence of periodontal disease expressed as the presence of at least one periodontal pocket of 4 mm and more, was higher in men and among the younger subjects (men aged 60-69 years: 85% vs. 71% in 70-79-year-old men; women aged 60-69 years: 71% vs. 62% in 70-79-year-olds). The prevalence of attachment loss of 3 mm or more followed a similar pattern. CONCLUSIONS: It seems therefore that in this population, the major oral health concern is related to caries and the small number of teeth retained among the dentate subjects.

Study of Health in Pomerania (SHIP): Relationship among socioeconomic and general health factors and dental status among elderly adults in Pomerania.

OBJECTIVE: The aim of this study was to evaluate associations among the dental status, socioeconomic factors, and general health of 1,877 subjects between the ages of 55 and 79. METHOD AND MATERIALS: Socioeconomic information (age, sex, education level) and questions on smoking and alcohol abuse were taken from an interview; income and medical information (number of diseases) were taken from a self-administered questionnaire; and HbA1C and CDT (diabetes and alcoholism markers) were taken from blood analyses. RESULTS: Of the subjects, 73% had a low education level, and 27% of the subjects had a monthly income of < 1,000 Euro and 13% of > 2,000 Euro. Twenty-six percent of the subjects were edentulous, and 29% had 20 or more teeth. The odds ratio of edentulism increased to 9.0 (95% confidence interval = 7.0-11.5) at the ages of 75 to 79 years compared to ages 55 to 79. Logistic regression analyses showed that edentulism was significantly associated with age, low education level, low income, smoking, and alcohol abuse. However, the retention of more than 20 teeth was associated with age. CONCLUSIONS: Age, low income, low education level, smoking, and alcohol abuse seemed to be risk markers for edentulism; whereas, the number of diseases, diabetes, and gender were not.

Evaluation of a nystatin-containing mouth rinse for terminally ill patients in palliative care.

PURPOSE: To evaluate the antifungal effect of a nystatin mouth rinse to control oral candidiasis of elderly patients in palliative care. MATERIALS AND METHODS: 52 cancer patients (mean age: 83 years) hospitalized in a long term care facility for chronically ill geriatric patients. Mouth rinsing with 15 ml nystatin solution (4,000 Ul/ml) was carried out for one minute, six times daily, over two weeks. Yeasts were collected and seeded on CHROMagar. Growth was read qualitatively and quantitatively after two days' incubation at 37 degrees C. RESULTS: Clinical signs of oral candidiasis were observed in 31% of cases. High yeast scores were observed in 58% of the residents. There was an association between signs of oral candidiasis and high yeast scores (p < 0.001). Treatment for two weeks caused no clinical changes nor reduced yeast scores. CONCLUSIONS: No clinical or antifungal effect from the nystatin suspension suggests that the concentration of nystatin in the mouth rinse was too low. A more effective procedure should be employed for antifungal treatment of terminally ill patients. Appropriate antimicrobial solutions with lubricating activity should be developed and applied to prevent oral diseases.

Prosthodontic status among old adults in Pomerania, related to income, education level, and general health (results of the Study of Health in Pomerania, SHIP).

PURPOSE: The aim of the study was to evaluate associations among prosthetic status, socioeconomic factors, and general health of subjects aged 55 to 79 years. The data were taken from the Study of Health in Pomerania (SHIP). MATERIALS AND METHODS: Socioeconomic information (age, sex, education level), medical information (number of diseases), and details on smoking and alcohol consumption were obtained. Prosthetic status in the maxilla and mandible was classified into complete denture (CD), removable partial denture (RPD), > or = 10 natural teeth or teeth replaced with fixed prosthodontics (10T+), and < or = nine natural teeth including fixed prosthodontics (9T-). RESULTS: The data of 1,877 subjects were evaluated. CDs in the maxilla were more frequent than in the mandible. RPDs were more frequent in the mandible and in the group aged 65 to 74 years. Of the individuals with a low education level, 47% had a CD in the maxilla, and only 21% had 10T+. However, of subjects with a high education level, 22% had a CD in the maxilla, and 54% had 10T+. The odds ratio of having a CD in the maxilla increased to 11.9 at the age of 75 to 79 years, compared to 0.6 at the age of 55 to 59 years. Logistic regression analyses showed that the risk of wearing a CD was significantly associated with old age, low education level, low income, smoking, and alcohol abuse, whereas the number of diseases (used as an indicator of general health) was not. CONCLUSION: Alcohol abuse, smoking, low education level, low income, and old age were significant predictors of wearing CDs.

Removable partial denture design: a need to focus on hygienic principles?

PURPOSE: The purpose of this study was to critically analyze important hygienic/secondary prophylactic and biomechanical aspects of removable partial denture (RPD) design. MATERIALS AND METHODS: The literature related to traditional biomechanical design and open/hygienic design of RPDs was discussed by the authors at a 2.5-day workshop. The written report was circulated among the authors until a consensus was reached. RESULTS: There is little scientific support for most of the traditional design principles of RPDs, nor has patient satisfaction shown any correlation with design factors. However, there is evidence that an open/hygienic design is more important than biomechanical aspects for long-term oral health. The biomechanical importance of some components is questioned, e.g., indirect retention and guiding planes. Alternative connector designs that reduce risks of tissue injury are described. Direct retainers and pontics are discussed in relation to the possibilities they offer for gingival relief. CONCLUSION: Greater attention should be paid to RPD design principles that minimize the risks of tissue injury and plaque accumulation in accordance with modern concepts of preventive dentistry.
