RESUMEN
AIMS AND OBJECTIVES: To evaluate the effect of chronic renal failure on oral health in renal dialysis patients. To assess and improvise awareness of staff regarding oral health care of the patients in hemodialysis unit. MATERIALS AND METHODS: A cross-sectional questionnaire survey and oral health examination study were conducted on 206 end-stage chronic renal failure patients (stage V) who were undergoing renal dialysis in Guntur city. The study included the questionnaire form and modified WHO proforma to record their oral health status. Oral examination was done in American Dental Association (ADA) type III method by using mouth mirror and community periodontal index (CPI) probe. Questionnaire survey was conducted among the nursing staff in the hemodialysis unit. RESULTS: Mean age of the study subjects was 46.79 ± 12.78 years; 81.1% were males and 18.9% were females. Candidiasis (8.3%) was the most frequently seen oral mucosal condition in these subjects. Majority of the subjects (44.2%) showed periodontal diseases (CPI score 3: Pocket depth of 4-5 mm). Caries prevalence of 56.3% was seen in this study group. Higher incidence of hepatitis C was significantly associated with higher duration of dialysis. There was very little awareness among the nursing staff regarding dental care. CONCLUSION: There is greater deterioration of periodontal health among dialysis patients with chronic renal disease. Awareness regarding dental care is very less among patients undergoing renal dialysis. These patients should be monitored carefully to maintain their oral health. Awareness must be increased among dialysis patients and nursing staff about the need for primary prevention of dental diseases.
RESUMEN
UNLABELLED: In recent years, it has become increasingly important to determine the age of living people for a variety of reasons, including identifying criminal and legal responsibility and for many other social events such as birth certificate, marriage, beginning a job, joining the army and retirement. OBJECTIVES: The aim of this study was to assess the developmental stages of mandibular third molar for estimation of dental age (DA) in different age groups and to evaluate the possible correlation between DA and chronological age (CA) in South Indian population. MATERIALS AND METHODS: Digital orthopantomography of 330 subjects (165 males, 165 females) who fit the study and the criteria were obtained. Assessment of mandibular third molar development was performed using Demirjian et al., modified method and DA was assessed using tooth specific stages. RESULTS AND DISCUSSION: The present study showed a significant correlation between DA and CA in both males and females. Third molar development commenced around 9 years and root completion takes place around 18.9 years in males and in females 9 years and 18.6 years respectively. Demirjian modified method underestimated the mean age of males by 0.8 years and females by 0.5 years and also showed that females mature earlier than males in selected population. CONCLUSION: Digital radiographic assessment of mandibular third molar development can be used to generate mean DA using Demirjian modified method and also the estimated age range for an individual of unknown CA. Since the Demirjian method is based on French-Canadian population, to enhance the accuracy of forensic age estimates based on third molar development, the use of population-specific standards is recommended.
