Association of edentulism and all-cause mortality in Chinese older adults: do sex differences exist?

OBJECTIVES: Previous studies revealed that tooth loss or edentulism was related to mortality. However, research in developing countries with large numbers of elderly populations is rare, and whether sex differences exist in this relationship is unknown. This study aimed to investigate the association between edentulism and 7-year all-cause mortality among older adults in China and whether sex differences existed. STUDY DESIGN: This was a prospective cohort study. METHODS: Data were from 2011 to 2018 waves of the China Health and Retirement Longitudinal Study. A total of 6538 participants aged ≥60 years were included. Logistic models were adopted to estimate the risks of mortality according to edentulism. RESULTS: The participants with edentulism at baseline were 20% more likely to die over 7 years after controlling for a set of covariates (odds ratio [OR] = 1.20, 95% confidence interval [CI]: 1.02-1.42). Moreover, edentulism was associated with a 35% higher odds of death among male participants (OR = 1.35, 95% CI: 1.08-1.70), whereas a significant association was not found in female participants. CONCLUSIONS: The findings demonstrated that baseline edentulism predicted all-cause mortality in Chinese older adults, and sex differences existed in this association. This study implied the importance of developing oral health education programs, incorporating dietary recommendations into dental care for edentulous patients, and expanding the coverage of dental services in the health insurance system to prevent edentulism and alleviate its negative outcomes for older adults.

Prediction Model Development and Validation of 12-Year Incident Edentulism of Older Adults in the United States.

INTRODUCTION: Edentulism affects health and quality of life. OBJECTIVES: Identify factors that predict older adults becoming edentulous over 12 y in the US Health and Retirement Study (HRS) by developing and validating a prediction model. METHODS: The HRS includes data on a representative sample of US adults aged >50 y. Selection criteria included participants in 2006 and 2018 who answered, "Have you lost all of your upper and lower natural permanent teeth?" Persons who answered "no" in 2006 and "yes" in 2018 experienced incident edentulism. Excluding 2006 edentulous, the data set (n = 4,288) was split into selection (70%, n = 3,002) and test data (30%, n = 1,286), and Monte Carlo cross-validation was applied to 500 random partitions of the selection data into training (n = 1,716) and validation (n = 1,286) data sets. Fitted logistic models from the training data sets were applied to the validation data sets to obtain area under the curve (AUC) for 32 candidate models. Six variables were included in all models (age, race/ethnicity, gender, education, smoking, last dental visit) while all combinations of 5 variables (income, alcohol use, self-rated health, loneliness, cognitive status) were considered for inclusion. The best parsimonious model based on highest mean AUC was fitted to the selection data set to obtain a final prediction equation. It was applied to the test data to estimate AUC and 95% confidence interval using 1,000 bootstrap samples. RESULTS: From 2006 to 2018, 9.7% of older adults became edentulous. The 2006 mean (SD) age was 66.7 (8.7) for newly edentulous and 66.3 (8.4) for dentate (P = 0.31). The baseline 6-variable model mean AUC was 0.740. The 7-variable model with cognition had AUC = 0.749 and test data AUC = 0.748 (95% confidence interval, 0.715-0.781), modestly improving prediction. Negligible improvement was gained from adding more variables. CONCLUSION: Cognition information improved the 12-y prediction of becoming edentulous beyond the modifiable risk factors of smoking and dental care use, as well as nonmodifiable demographic factors. KNOWLEDGE TRANSFER STATEMENT: This prediction modeling and validation study identifies cognition as well as modifiable (dental care use, smoking) and nonmodifiable factors (race, ethnicity, gender, age, education) associated with incident complete tooth loss in the United States. This information is useful for the public, dental care providers, and health policy makers in improving approaches to preventive care, oral and general health, and quality of life for older adults.

Efficacy and risks of tooth-supported prostheses in the treatment of partially edentulous patients with stage IV periodontitis. A systematic review and meta-analysis.

AIM: The aim was to evaluate the efficacy and effectiveness of tooth-supported fixed prostheses in partially edentulous patients with stage IV periodontitis. MATERIAL AND METHODS: Randomized and controlled clinical trials (RCTs and CCTs) and prospective/retrospective cohort studies or case series were searched in three databases. Survival rate of abutment teeth was considered the primary outcome. Meta-analyses were performed whenever possible. RESULTS: Twenty-four publications were included. No RCTs or CCTs compared the efficacy of tooth-supported fixed prostheses between patients with severe periodontitis or non-periodontitis patients. Most of the data retrieved were derived from case series. The incidence of abutment-tooth loss after a follow-up period from 2 to 35.4 years was low (n = 17 studies; weighted mean incidence (WMI) = 4.8%; confidence interval (CI) [3.2, 6.5]). The corresponding figure for prostheses failure was WMI = 6.9% (n = 18; 95% CI [4.1, 9.7]). Technical complications seemed to be more frequent than biological complications (caries, endodontic failure, root fracture, etc.). Periodontal outcomes tended to remain stable over time. CONCLUSION: Tooth-supported fixed prostheses seemed to be a valid treatment approach to restore masticatory function in patients with stage IV periodontitis once periodontal therapy has been accomplished. However, the comparative efficacy of this treatment among periodontitis and non-periodontitis patients is unclear due to the absence of clinical trials.

Association Between Tobacco Smoking, Dental Status and Self-perceived Oral Health in Elderly Adults in Colombia.

Tobacco smoking is responsible for several health problems, including mouth diseases. The aim of the present study was to establish the association between smoking and dental status and self-perceived oral health in a large group of elderly Colombian adults. Analysis of 18,937 survey records of participants aged ≥ 60 years old was conducted. Information regarding age, sex, skin color, socioeconomic level, education, marital status, denture use, partial tooth loss or edentulism, Geriatric Oral Health Assessment Index (GOHAI) and tobacco smoking was retrieved from the database. A descriptive analysis and multivariate logistic regression analysis were performed. Half of the participants were edentulous in the maxilla while mandibular teeth were more frequently retained in more than 60% of the participants. After adjusting for sex and age, smoking consistently increased the odds of partial or complete edentulism in the maxilla (OR 1.05; 95% CI 1.02-1.09) and mandible (OR 1.04; 95% CI 1.00-1.08). Nonetheless, the increase in the odds in the mandible was not statistically significant. The habit of smoking was associated with increased tooth loss that in the long-term may result in poor oral health affecting the quality of life of elderly people.

Factors Associated With Becoming Edentulous in the US Health and Retirement Study.

BACKGROUND/OBJECTIVE: To determine factors associated with older adults becoming edentulous (complete tooth loss). DESIGN: Longitudinal study over a 6-year period. SETTING: United States, 2006, 2012. PARTICIPANTS: Nationally representative US sample of adults, aged 50 years and older (n = 9982), participating in the Health and Retirement Study in 2006 and 2012. At the outset, they were dentate and not institutionalized. INTERVENTION: None. MEASUREMENTS: Self-report of being dentate or edentulous, demographic variables, dental utilization and other health behaviors, self-rated general health, and incidence between 2006 and 2012 of comorbid medical conditions, functional limitations, and disabilities. RESULTS: From 2006 to 2012, 563 individuals (5%) became edentulous and 9419 (95%) remained dentate. Adults who became edentulous by 2012 were more likely than those who remained dentate to be black/African American compared to white, to be less educated, were current smokers, had diabetes, and reported poorer self-rated general health, more functional limitations and disabilities, and fewer dental visits (all P < .0001), among other factors. Of those with regular dental visits (at least once every 2 years during the 6-year period), 2.3% became edentulous compared to 9.9% among those without regular dental visits. After adjusting for age and other potential confounders, there was a strong association with poor dental attendance and smoking. Nonregular dental attenders were more likely than regular attenders to become edentulous (odds ratio [OR] = 2.74; 95% confidence interval [CI] = 2.12-3.53), and current smokers were more likely than never smokers to become edentulous (OR = 2.46; 95% CI = 1.74-3.46). CONCLUSION: Although more contemporaneous data are needed to determine causality, regular dental utilization and smoking are modifiable factors that could prevent edentulism, even when many other comorbid conditions are present.

Conclusiones: dentro de los factores asociados a dicho fenómeno cabe destacar: la edad, la presencia de obturaciones y la higiene bucal. La principal causa de desdentamiento fue la caries dental(AU)

Background: the loss of teeth can affect people of any age and although this is more frequent in the elder, presently it has increased the number of young persons that from early ages, present lost teeth. Objective: to identify the associated factors to the tooth loss in teenagers of the municipality of Cifuentes. Methods: a descriptive epidemic study of traverse court was carried out in the Municipality of Cifuentes from September, 2015 to March, 2017.The universe of population was constituted for ages between 12 and 18 years conformed by a total of 465 students, of them 180 were selected by means of a probabilistic sampling by two-stage stratified conglomerates. Results: the loss of teeth in the adolescents was of 17.2 percent same to the number of filled, the oral hygiene to regulate it was present in 51.7 percent also in the 58.2 percent the cause of teeth loss was a dental caries.Conclusions: among the factors associated to this phenomenon it is necessary to highlight: the age, the presence of filled and oral hygiene. The main cause of teeth loss was a dental cavity(AU)

The prevalence of edentulism and their related factors in Indonesia, 2014/15.

BACKGROUND: Little information exists about the loss of all one's teeth (edentulism) among older adults in Indonesia. The aim of this study was to investigate the prevalence of edentulism and associated factors among older adults in Indonesia. METHOD: This study examines the self-reported prevalence of edentulism and associated factors among older adults (50 years and older) in a cross-sectional national study using the Indonesia Family Life Survey IFLS-5, 2014/15. The community-based study uses a multi-stage stratified sampling design to interview and assess household members, with a household response rate of over 90%. RESULTS: The overall prevalence of edentulism was 7.2, 29.8% in 80 years and older and 11.8% in those with no formal education. In adjusted Poisson regression analysis, older age, living in five major island groups and having functional disability were associated with edentulism. In addition, among men, having quit and current tobacco use and among women, having low social capital were associated with edentulism. Further, in adjusted analysis, among men, edentulism was positively associated with hypertension and negatively associated with diabetes, and among women, edentulism was associated with functional disability. CONCLUSIONS: Results suggest that overall and/or among men or women that older age, living in five major island groups, having functional disability, tobacco quitters and users and those with low social capital was associated with edentulism. The identified associated factors of edentulism may be utilized in oral health programmes targeting older adults in Indonesia.

Natural history of periodontitis: Disease progression and tooth loss over 40 years.

OBJECTIVES: To assess long-term attachment and periodontitis-related tooth loss (PTL) in untreated periodontal disease over 40 years. MATERIAL AND METHODS: Data originated from the natural history of periodontitis study in Sri Lankan tea labourers first examined in 1970. In 2010, 75 subjects (15.6%) of the original cohort were re-examined. RESULTS: PTL over 40 years varied between 0 and 28 teeth (mean 13.1). Four subjects presented with no PTL, while 12 were edentulous. Logistic regression revealed attachment loss as a statistically significant covariate for PTL (p < .004). Markov chain analysis showed that smoking and calculus were associated with disease initiation and that calculus, plaque, and gingivitis were associated with loss of attachment and progression to advanced disease. Mean attachment loss <1.81 mm at the age of 30 yielded highest sensitivity and specificity (0.71) to allocate subjects into a cohort with a dentition of at least 20 teeth at 60 years of age. CONCLUSIONS: These results highlight the importance of treating early periodontitis along with smoking cessation, in those under 30 years of age. They further show that calculus removal, plaque control, and the control of gingivitis are essential in preventing disease progression, further loss of attachment and ultimately tooth loss.

Christ Siemens Touraine syndrome: A rare case report.

Christ-Siemens-Touraine (CST) is a rare hereditary disorder of X-linked recessive trait, characterized by abnormal development of two or more structures or tissues of ectodermal origin. The common clinical findings include hypodontia, hypohydrosis, hypotrichosis, and onychodysplasia. Although hypodontia is common, anodontia is a rare feature. Most of the patients are suffering from social rejection and consequent psychological trauma because of the facial dysmorphism and absence of multiple teeth. Oral rehabilitation is of prime importance for such patients. This article presents a case in a 5½-year-old boy presenting with altered manifestations affecting almost all the ectodermal structures like skin, hair, nails, teeth, sebaceous glands, sweat glands, salivary glands, mammary glands, and tear glands. He also had complete anodontia and dry mouth. A multidisciplinary treatment was given to the patient with the collaboration of various health professionals. The child gained confidence and was relieved from the psychological impact following the prosthetic rehabilitation.

Edentulism and transplant-associated complications in patients with multiple myeloma undergoing autologous hematopoietic stem cell transplantation.

PURPOSE: Patients undergoing autologous hematopoietic stem cell transplantation (HSCT) are at risk for oral complications which may cause significant morbidity. The aim of this study was to compare the incidence of toxicities and complications in edentulous and dentate patients undergoing autologous HSCT for multiple myeloma. METHODS: We conducted a retrospective case-control study to analyze the incidence of bacteremia, fever, and oral mucositis, between edentulous and dentate patients. All patients underwent dental evaluation, received dental treatment if indicated, and were cleared before transplantation. The two groups were matched for age, gender, ethnicity, disease stage, time from diagnosis to transplant, performance status, and conditioning regimen. RESULTS: A total of 45 edentulous and 90 dentate patients were enrolled. All patients were male with a median age of 60 years and a mean performance status by Karnofsky score of 90 %. Two thirds had stage III MM with a median time from diagnosis to transplantation of 12 months, and all received melphalan as part of the conditioning regimen. The incidence of bacteremia (p = 0.553), fever (p = 0.245), severity of oral mucositis (p = 0.465), and other post-transplant toxicities were similar between both groups. CONCLUSIONS: There were no significant differences in the incidence of bacteremia, fever, severity of oral mucositis, or other complications between edentulous and dentate patients with multiple myeloma after autologous HSCT.

Association between adult height and tooth loss in a representative sample of Koreans.

OBJECTIVES: Evidence suggests that taller individuals have better health than that of shorter individuals. However, evidence for links to tooth loss is scarce. The aim of this study was to examine the association between adult height and tooth loss and to examine the roles of covariates in explaining the association in different birth cohorts in Korea. METHODS: Using data from the Fourth and Fifth Korea National Health and Nutritional Examination Survey (KNHANES IV and V), the subjects were grouped into two birth cohorts based on their historical context: born from 1920 to 1945 and 1946 to 1962. The dependent variables were loss of 8 or more teeth and total tooth loss (edentulism), while the independent variable was the height quartile. Demographic factors (survey year, age, and gender), early childhood/adult socioeconomic status (SES) (father's education, own education, income, and place of residence), health behaviors (cigarette smoking, binge drinking, frequency of toothbrushing, and regular dental visit), and health problems (diabetes and hypertension) were included in a series of analytical models. RESULTS: The survey year-, age-, and gender-adjusted prevalence ratios (PR) of the loss of 8 or more teeth for the shortest quartile were 1.23 (95% confidence intervals, CI: 1.13-1.35) for the 1920-1945 birth cohorts and 1.39 (95% CI: 1.20-1.62) for the 1946-1962 birth cohorts. The PRs for edentulousness were 1.64 (95% CI: 1.34-2.02) for the 1920-1945 birth cohorts and 2.26 (95% CI: 1.31-3.91) for the 1946-1962 birth cohorts. These associations were moderately attenuated after adjusting for own education but still significant in the fully adjusted models. After full adjustment for the covariates, those in the shortest height quartiles in the relatively young birth cohorts (1946-1962 birth cohorts) had a 1.93 (95% CI: 1.09-3.43) times greater prevalence of edentulism than that of their tallest counterparts. CONCLUSIONS: Given that adult height reflects early-life conditions, independent associations between height and tooth loss support the view that early-life circumstances significantly influence oral health outcomes in later life.

Oral health-related quality of life of edentulous patients after complete dentures relining.

BACKGROUND/AIM: Tooth loss affects oral health-related life quality. More than a third of edentulous patients are not fully satisfied with their complete dentures and mainly complain of insufficient stability, retention, and pain during mastication. Solving the problem may include relining by materials that are based on silicone or acrylic. The aim of this study was to determine the level of patients' satisfaction before and after relining upper dentures with soft and rigid liners. METHODS: The patients (n=24) were divided into two study groups. Maxillary denture relining of the first group of patients was performed with hard acrylic based resins while in the second group of patients complete denture was relined with a silicone-based soft liner. They were asked the questions from the specifically adapted the Oral Health Impact Profile Questionnaire for edentulous patients before and three months after relining dentures. RESULTS: After relining the patients showed a higher degree of satisfaction with their dentures in all the tested domains (masticatory function, psychological discomfort, social disability and retention and hygiene). The padents with soft denture relines were more satisfied. CONCLUSION: Refining of maxillary complete dentures significantly positively impacts the quality of life of patients in all the tested domains (masticatory function, psychological discomfort, social disability, pain and oral hygiene). Better results were achieved using a silicone-based soft liner, which recommends it as the material of choice for relining dentures.

Restoration of Oral Function for Adult Edentulous Patients with Ectodermal Dysplasia: A Prospective Preliminary Clinical Study.

BACKGROUND: Therapy with zygomatic implants (ZIs) or conventional implants (CIs) has proven to be an effective method to restore oral function for systemically healthy patients. However, it is still a major challenge to fully restore oral function to edentulous adult patients with ectodermal dysplasia (ED). PURPOSE: The aim of this study was to determine an effective treatment protocol for restoring oral function using ZIs and CIs to edentulous adult ED patients. MATERIALS AND METHODS: Ten edentulous adult ED patients were treated in this study. The treatment protocol involved the following: (1) bone augmentation in the region of the anterior teeth; (2) placement of two ZIs and four CIs in the maxilla, and four CIs in the mandible; (3) fabrication of dental prosthesis; and (4) psychological and oral education. Following treatment of these patients, implant success rates, biological complications, patient satisfaction, and psychological changes were recorded. RESULTS: Although there was evidence of bone graft resorption in the maxilla, bone augmentation of the mandible was successful in all patients. Nine CIs in the maxilla failed and were removed. All ZIs were successful, and the CIs success rates were 77.50% in the maxilla and 100% in the mandible, with a mean of 88.75%. The mean peri-implant bone resorption for the CIs ranged from 1.3 ± 0.4 mm to 1.8 ± 0.6 mm, and four cases exhibited gingival hyperplasia in the maxilla and mandible. One hundred percent of the patients were satisfied with the restoration of their oral function, and >50% of the patients exhibited enhanced self-confidence and self-esteem. CONCLUSIONS: This study demonstrates that oral function can be restored in edentulous adult ED patients using a comprehensive and systematic treatment protocol involving psychological and oral education, bone augmentation, implant placement, and denture fabrication. Despite these positive outcomes, bone augmentation remains challenging in the anterior region of the maxilla for edentulous adult ED patients.

A population-based study of edentulism in the US: does depression and rural residency matter after controlling for potential confounders?

BACKGROUND: Oral health is an integral component of general health and well-being. While edentulism has been examined in relation to socioeconomic status, rural residency, chronic disease and mental health, no study that we know of has examined edentulism and these factors together. The objective of this study was to determine whether depression and rural residency were significantly associated with partial and full edentulism in US adults after controlling for potential confounders. METHODS: 2006 Behavioral Risk Factor Surveillance Survey (BRFSS) data were analyzed to identify factors associated with increased odds of partial or full edentulism. This year of BRFSS data was chosen for analysis because in this year the standardized and validated Personal Health Questionnaire-8 (PHQ-8) was used to measure current depression. This measure was part of the optional questions BRFSS asks, and in 2006 33 states and/or territories included them in their annual surveillance data collection. Bivariate and logistic regression analyses were performed on weighted BRFSS data. RESULTS: Logistic regression analysis using either full or partial edentulism as the dependent variable yielded that rural residency or living in a rural locale, low and/or middle socioeconomic status (SES), depression as measured by the PHQ-8, and African American race/ethnicity were all independent risk factors when controlling for these and a number of additional covariates. CONCLUSIONS: This study adds to the epidemiological literature by assessing partial and full edentulism in the US utilizing data from the CDC's Behavioral Risk Factor Surveillance System (BRFSS). Examining data collected through a large national surveillance system such as BRFSS allows for an analysis that incorporates an array of covariates not available from clinically-based data alone. This study demonstrated that current depression and rural residency are important factors related to partial and full edentulism after controlling for potential confounders.

Effects of calcitonin and calcium medication in treatment of edentulous osteoporotic mandible.

BACKGROUND/AIM: In addition to damage of the bones that support the remaining teeth, degradation of osteoporotic oral bones also lead to a consequent reduction of supporting tissues and the loss of dentures retention. The aim of this study was to assess the clinical and radiographic outcomes following injection of a calcitonin and calcium solution into the buccal aspects of edentulous mandibles. METHODS: The experimental group of 67 edentulous patients diagnosed with osteoporosis, and the control group of 19 nonosteoporotic edentulous patients were treated with the calcitonin and calcium once solution per month. Mandibular bone density was measured from panoramic radiographs, supplemented by T scores of skeletal density in the experimental group. RESULTS: After the therapy, measurements showed moderate increases in bone density, compensating for up to 4% of the total loss of minerals and solidity of denture-bearing areas of osteoporotic mandibles. Osteoporosis affected women earlier than men in this study. CONCLUSION: Application of a calcitonin and calcium solution is a suitable method of preprosthetic therapy for edentulous osteoporotic patients.

Sex/Gender differences in tooth loss and edentulism: historical perspectives, biological factors, and sociologic reasons.

This review highlights what is known regarding differences in tooth loss by sex/gender, and describes: gender-related tooth ablation (the deliberate removal of anterior teeth during life) found in skulls from history and prehistory; potential mediators of the relationship between sex/gender and tooth loss; the current epidemiology of gender differences in tooth loss (limited to North America); and risk factors for tooth loss in the general population and in women.

Factors associated with edentulousness in an elderly population in Valencia (Spain) / Factores asociados con el edentulismo en población anciana de Valencia (España)

Objective: To determine the prevalence of edentulism and its association with various socioeconomic factors and oral health habits in the population aged 65-74 years old in the region of Valencia. Methods: A cross sectional study was designed. Thirty-four primary health centers and five nursing homes were chosen at random in the region of Valencia (10-15 voluntary participants per sampling point). Clinical examinations were carried out by three calibrated dentists (kappa>0.85) in the same centers. The total sample consisted of 531 individuals (235 men and 296 women). Results: The percentage of toothlessness was 20.7% and the mean number of natural teeth present was 14.92. The prevalence of edentulism was significantly higher (p <0.05) in men, institutionalized persons, those with no schooling, those with poor oral hygiene, those who visited the dentist regularly and those living in peri-urban/rural areas. In a multivariate logistic regression model with edentulism as the dependent variable, the following factors were identified as significant independent variables: institutionalization (odds ratio [OR]=2.88), poor oral hygiene (OR=2.35), regular visits to the dentist (OR=2.34) and age (OR=1.19). Conclusion: Edentulousness is a complex phenomenon that involves distinct social and economic factors (AU)

Objetivo: Determinar la prevalencia del edentulismo y su asociación con diferentes factores socioeconómicos y de hábitos de salud oral en la población valenciana de 65 a 74 años de edad. Métodos: Se diseñó un estudio transversal. Se seleccionaron aleatoriamente 34 centros de salud de atención primaria y cinco residencias geriátricas de la Comunidad Valenciana (10 a 15 individuos voluntarios por punto de muestreo). Las exploraciones clínicas las realizaron tres odontólogos previamente calibrados (kappa>0.85) en los mismos centros. La muestra total fue de 531 personas, 235 hombres y 296 mujeres. Resultados: El porcentaje de desdentados totales fue de 20,7, y la media de dientes naturales presente de 14,92. La prevalencia de edentulismo fue significativamente mayor (p <0.05) en los hombres, en las personas institucionalizadas, que no tienen estudios, con pobre higiene oral, que visitan regularmente al odontólogo y en las que viven en zonas periurbanas o rurales. En un modelo de regresión logística multivariada con el edentulismo como variable dependiente se han hallado como variables significativas la institucionalización (odds ratio [OR]=2,88), la pobre higiene oral (OR=2,35), las visitas regulares al odontólogo (OR=2,34) y la edad (OR=1,19). Conclusión: El edentulismo es un fenómeno complejo, con diversos factores sociales y económicos implicados (AU)

Epidemiological survey on edentulousness.

UNLABELLED: India has a large geriatric population of 77 millions, comprising 7.7% of its total population. One of the major handicaps in the elderly is loss of teeth, affecting their mastication, dietary intake and nutritional status. AIMS AND OBJECTIVES: The present study was planned to assess the level of edentulousness, cause of edentulousness, denture wearing and denture needs of the middle and elderly in the society and study was correlated between habits and socioeconomic variables, diet and body mass index (BMI). MATERIALS AND METHODS: A total of 500 subjects (random sampling) from dental outpatient were studied. A prepared questionnaire was developed, explained, interviewed and questions were filled personally. RESULTS: The level of edentulousness was found to be high in the subjects with low socioeconomic status and in advancing age with no significant difference between male and females. Another finding was very low level of denture wearing of 62% needing complete denture and partial denture only 10.4% of subjects wearing dentures. Mixed diet population had higher level of edentulousness compared with vegetarians. The BMI was correlated with level of edentulousness. CONCLUSION: The study clearly showed that there is lack of dental awareness, so dental education and motivation in very important. The study concludes that the need for prosthodontics care will increase due to the increase in life span. This study is clinically significant with regard to knowing the root cause of edentulism, either partial or complete. Out of 62% tooth loss, dental caries (37.4%) topped the cause for tooth loss followed by combination of dental caries and periodontal disease (12.2%).

Aggressive external root resorption of the entire dentition accompanied by osteolysis: a case report.

A healthy Caucasian male lost all of his teeth because of aggressive cervical, apical, and lateral root resorption over a period of 11 years. Microscopically, there was no sign of reparative cementum apposition, but cell-rich fibrous connective tissue filling the deep resorptions was seen. The resorbed teeth were surrounded by fibro-osseous tissue of osteolytic appearance, as noted during radiologic examination. Radiography showed the osteolytic processes to regress dramatically with the removal or loss of teeth. No underlying systemic or local factor was identified. In spite of endodontic and surgical treatment, none of the resorptions went into remission.

[Severe periodontitis, edentulism and neuropathy in patients with type 2 diabetes mellitus]. / Periodontitis severa, edentulismo y neuropatía en pacientes con diabetes mellitus tipo 2.

UNLABELLED: Periodontitis is a frequent pathologic condition in diabetic patient, and has been associated with chronic complications like nephropathy, cardiovascular disease, peripheral artery disease or death. OBJECTIVE: To document the association between severe periodontitis and edentulism with the presence of sensory-motor neuropathy in diabetic patients. MATERIAL AND METHOD: Cross-sectional study in type 2 diabetic patients from the family medicine unit no. 27 of the IMSS in Tijuana, México. Patients were evaluated to identify periodontitis and sensory-motor neuropathy. Information was also obtained about sex, age, duration of diabetes, glycemic control, smoking and alcohol use. RESULTS: Four hundred and thirty-six patients completed all measurements. In 180 (41.3%) neuropathy was identified, and associated with age (p < 0.001); duration of diabetes (p < 0.001); fasting glucose (p < 0.001); severe periodontitis (OR: 2.7; IC 95%: 1.5-4.8);and with edentulism (OR: 4.4; IC 95%: 2.0-9.4). Logistic regression multivariable analysis kept as significative the association between severe periodontitis and edentulism with neuropathy (adjusted OR: 1.7; IC 95%: 1.1-2.6). CONCLUSIONS: Periodontitis and edentulism are associated with the presence of neuropathy in diabetic patients.
