Background: Mouth self-examination (MSE) is shown as a speedy, economical, and effortless method of oral cancer detection. As previous studies were conducted in population with high literacy, the current survey was performed to explore the usefulness of MSE for finding the oral cancerous precancerous lesions in indigenous low literate population of Dehradun district. Materials and Methods: It is a cross-sectional survey which was done on the Buksa tribal communities in Dehradun district, India. Out of seven tehsils in the district, two were randomly selected, from which two villages were selected. Individuals belonging to Buksa tribe above the age of 18 years were gathered in commonplace. A total of 539 people who gave their consent were enrolled for study. Using a questionnaire, information regarding sociodemographic details, history of risk factors, and practice of MSE was obtained by interview method, followed by recording oral findings by a single expert. Later, performance of MSE was taught to the participants and they were asked to record the same. Descriptive analysis and Chi-square test were applied wherever applicable and significance level was kept at below 0.05. Results: It was observed that out of 539 participants, 220 (40.8%) practiced MSE and 319 (59.2%) have never practiced MSE. Further analysis showed that a total of 39% males and 42.7% females had MSE habits and this difference was not statistically significant ( P > 0.05). In totality, the prevalence of oral lesions identified by health worker was 213 (39.5%), whereas MSE showed only prevalence rate of 69 (12.8%). MSE had low sensitivity (24.6%), whereas high specificity (87.4%) for all the lesions and most sensitive in detecting ulcers (72.7%), and highest specificity in identifying red lesions (99.2%). Conclusion: Even though the sensitivity of MSE for detecting oral premalignant/malignant lesions was low, specificity was very high. Frequent efforts to educate and encourage public on MSE may enhance efficacy and compliance.

A BSTRACT Background: The purpose of this study was to measure primary health care providers’ understanding of the significance of health literacy and self-efficacy in cigarette quitting. Material and Methods: The current study used a quantitative descriptive questionnaire to collect data. The research was carried out among primary health care providers in a rural location near the Azamgarh Dental College in Uttar Pradesh. Medical officials, nursing personnel, and dental practitioners, if existent, are examples of primary health professionals. Azamgarh district is divided into 22 blocks. 22 primary health facilities were selected from these 22 blocks. 54 medical officers and 98 other primary health workers (ANMs, GNMs, and Asha workers) were questioned at these primary health facilities. Results: The majority of study participants {132 (86.84%)} were aware of the bad effects of tobacco consumption. Most of the study participants don’t know about health literacy {115 (75.65%)} and self-efficacy {78 (51.32%)}. The majority of them did not know the questionnaire to test health literacy {114 (75.02%)} and self-efficacy {150 (98.68%)}. poor mean awareness score (20.77 ± 3.33) was significant (p = 0.001) in the age group 25-35 years. Anganwadi workers were having significantly (p = 0.002) highest poor awareness score (22.67 ± 2.34). Conclusion: From the above results, it was concluded that awareness of the role of health literacy and self-efficacy in tobacco cessation among primary health workers was poor. Almost all study participants had not attended any training programs on tobacco cessation.

Aim and objective The growth of the temporomandibular joint (TMJ) gets affected by multiple factors like aging, occlusion state, and by the movement of the jaw while masticating and swallowing. Radiographic imaging is often utilized as a vital diagnostic adjunct in the evaluation of certain examinations of the TMJ. Materials and methods In this in vivo study, 30 male participants with mean age 55 years, having edentulous maxillary and mandibular arches from the Outpatient Department of Prosthodontics, were randomly selected. Group I (n = 30) patients who were edentulous for the last 4–5 years but without wearing dentures. Whereas group II (n = 30) patients who were edentulous for the last 4–5 years but were wearing dentures for this period. Maxillary and mandibular dentures were fabricated and delivered to subjects. Subjects were subjected to the TMJ analysis with the help of CBCT. Radiological images of dentomaxillofacial structures were analyzed by a specialist with a dual monitor inside a darkened silent room. On the monitor, three times measurements were recorded followed by calculation of mean value. The recordings were taken on both sides and thus, 210 sites were analyzed altogether, followed by the statistical analysis using SPSS software version 15.0. Results The mean ages of group I and II were 59.00 ± 6.74 and 58.27 ± 6.75 years, respectively. The intra- and intergroup comparisons were done using a one-sample t-test. Differences in mean intercondylar width in groups I and II were not found to be statistically significant. The difference in mean length of glenoid fossa was not statistically significant at any of the above observation periods. A continuous decline in mean length of glenoid fossa was observed with time in both groups. The range of change in articular eminence length was found to be statistically significant for both the groups (p < 0.05). Conclusion This study shows that the articular eminence flattening is correlated with age; on the other hand, the rate of deformation was found significantly more in total edentulous subjects as compared to subjects having normally maintained occlusion. The anatomical changes inside the TMJ have been much greater expressed within the completely edentulous subjects in whom the angle of sagittal condyle path declines and so does the articular eminence height. Clinical significance It is essential to provide the edentulous patient with early prosthetic and occlusal rehabilitation after extractions to prevent the anatomical changes in TMJ.
