Categorical analysis of factors affecting needs and demands for removable dentures among Alexandria Dental Research Center clientele

An accurate assessment of dental needs is important to public health planners. With this information, it is possible to assess future treatment needs and demands for services including those for removable dentures. The present work aimed to estimate the magnitude and types of needs, and demands for partial or complete removable dentures, to study some factors that may affect the identified needs and demands for removable dentures, in addition to studying the factors that may affect satisfaction with the dentures. The present study was conducted in "Alexandria Dental Research Center". Data were collected by means of interview questionnaire, followed by dental examination of all patients attending the center for the sake of removable dental restorations for a period of 6 months. A further follow up over a period of three months was undertaken to the 330 cases recorded. About one third of the cases demanded partial and/or complete dentures and were above 60 years old. The first purpose for construction of new dentures was mastication, followed by cosmetics. Only one quarter of cases decided to have delayed immediate dentures. Diabetics and those having chronic diseases showed more demand for complete dentures. The most discriminating variable between the demand for different dentures was the missing in the lower anterior teeth followed by missing in the upper both anterior and posterior and then missing in the upper anterior teeth. Satisfaction score increased with advance of age, among males, among those for complete dentures, and those who had had previous dentures. Stepwise logistic regression revealed that the best predictor for overall satisfaction was the history of having previous dentures. Results of the present study, suggest that early screening and treatment of diabetic patients, gathering detailed information by means of a questionnaire before new dentures fabrication may be an important tool for the dentist in predicting and consequently enhancing patient satisfaction with the dentures. Health education should stress on the value of restoring missing teeth and all available options around this.     

Urban/Rural Differences in Prosthetic Dental Service Rates

There have been few reports of relative rates of provision of dental health services in rural and urban settings, a comparative measure of access to care in these populations. One part of a statewide survey of active North Carolina general dentists (n=959, response rate=47%) was designed to quantify provision of prosthetic services. To determine contrasting rural and urban rates, responses were analyzed according to dentists'self-report of practice city size using analysis of covariance with percent of insured patients in the practice as the covariate. Mean per-patient-visit rates for crowns, fixed partial dentures, removable partial dentures, and extractions, as well as the distributions of treatment following tooth extraction, differed by city size, with practitioners in the smallest cities reporting treatment distributions reflecting more frequent loss of teeth and less frequent replacement. These differences in patterns of prosthetic care echo the limited existing information describing oral health status, provider supply, and receipt of care, all of which suggest that differential levels of access to care exist and lead to differences in oral health outcomes.

Prosthetic treatment in the adult French population: Prevalence and relation with demographic,socioeconomic and medical characteristics

BackgroundThe aim of this study was to estimate the prevalence of dental prosthetic treatment and to investigate the demographic, social, economic and medical factors associated with the use of fixed and removable dentures in a representative sample of adults living in France.MethodsThe data were obtained from the 2002–2003 Decennial Health Survey, a cross-sectional study of a representative sample of the population living in France, which included 29,679 adults. Information was collected by interview. The variables collected were fixed denture, removable denture, age, gender, number of children, area of residence, nationality, educational attainment, family social status, employment status, annual household income per capita, supplementary insurance, chronic disease, eyesight problems/glasses, hearing problems/hearing aids. Multinomial logistic regression models were used to study the relationship between prosthetic treatment and demographic, socioeconomic and medical characteristics unadjusted, adjusted for age and adjusted for all the characteristics.ResultsThe prevalence of prosthetic treatment was 34.6% (95% confidence interval (CI): [34.1; 35.2]) for fixed prosthetic dentures and 13.8% (95% CI: [13.4; 14.2]) for removable prosthetic dentures. We showed a gradient between educational attainment and removable dentures; the odds ratio adjusted for all the variables (aOR) associated with no or primary education compared to post-secondary education was 2.56; 95% CI: [2.09; 3.13]. When annual household income per capita was low, subjects were less likely to report fixed dentures (aOR = 0.68; 95% CI: [0.62; 0.75]) than those with high annual household income per capita. Individuals without insurance less often reported fixed dentures than those with private insurance. Those reporting chronic disease were less likely to report fixed dentures (aOR = 0.87; 95% CI: [0.79; 0.95]) but more likely to report removable dentures (aOR = 1.29; 95% CI: [1.17; 1.43]) than those without chronic disease.ConclusionThis study reveals social, economic and medical inequalities in fixed and removable prosthetic treatment among adults in France.     

Evaluation of the impact on quality of life caused by oral health problems in adults and the elderly in a southeastern Brazilian city

The scope of this paper was to evaluate the prevalence of the impact of oral health problems on quality of life, and its association with socio-demographic and clinical variables and the use of dental services by adults and the elderly in Marechal Floriano. A cross-sectional study was conducted on a random sample of 237 participants. Data was collected by Municipal Community Health Agents using four questionnaires with items about the socio-demographic and oral health status of the participants, dental practice structure and oral health impact profile (OHIP-14). The greatest impact perception related to oral health problems was found in individuals over 40 years of age (OR= 2.37 IC 95%=1.375;4.098), those with a perceived need for removable partial dentures (OR= 2.771 IC 95%=1.488;5.162), and full removable dentures (OR= 2.292 IC 95%=1.305;4.026). The impact prevalence was of 35% and revealed an association with age and the perceived need for partial and full dentures. Subjective indicators must be used in conjunction with objective indicators to determine the population's treatment needs, thereby improving oral health and quality of life of the population.     

Dental implants: a better anchor for dentures

Loss of teeth results in resorption of the jaws. As a consequence the denture bearing area progressively reduces, eventually causing loss of retention and stability of the conventional denture. In three patients, two women aged 36 and 37 and a man aged 46, suffering from severe problems with their conventional dentures endosteal implants were inserted in the jawbone. After the healing period the dentist fabricated an implant-retained overdenture. The patients were very satisfied with the final result. Endosteal implants are, especially in the mandible, a reliable treatment modality for a stable implant-retained denture in case of patients suffering from retention problems with their conventional dentures.     

依从性等因素对于活动义齿适应性的关系探讨

目的探讨性别、年龄及依从性对患者佩戴活动义齿适应性的影响,为缩短活动义齿的适应周期提供临床依据。方法选取2018年12月-2019年12月笔者所在医院收治的活动义齿修复患者116例为研究对象,比较不同性别、年龄及依从性患者佩戴活动义齿的适应性。结果不同性别患者在活动义齿适应性的比较,差异无统计学意义(P>0.05)。不同年龄患者在活动义齿适应性的比较,差异有统计学意义(P<0.05):61~70岁的患者活动义齿适应性最理想,71~80岁之间次之,80岁以上最不理想。依从性组患者对活动义齿的适应性与不稳定依从组比较,差异具有统计学意义(P<0.05)。结论随着年龄的增长患者佩戴活动义齿的适应性逐渐下降,而依从性好的患者比依从性差者佩戴活动义齿的效果更好,适应期也更短。
