Consanguineous marriage as a key indicator of isolated congenital dental anomaly among South Indian population - A cross-sectional study.

Background: Orofacial anomalies occur due to incomplete fusion of developmental lines in the head and neck region. Dental anomalies regarded as the most common orofacial anomalies either in isolated or syndromic forms arise due to genetic and environmental factors. Among genetic influences, consanguineous marriages are considered as a significant predisposition factor in the transmission of congenital defects and several autosomal recessive diseases from one generation to other with an increased risk of detrimental effects on offspring. Aim: The present study was aimed to evaluate the prevalence and significant association between consanguinity and isolated dental anomalies with that of nonconsanguineous parents among south-Indian population. Methodology: A total of 116 participants with and without dental anomalies in isolated form pertaining to tooth size, shape, altered morphology, number and eruption were selected followed by brief case history. Participants with a positive history of consanguinity were categorized as Group A while others were categorized under Group B. Results: Sixty-four out of 116 participants (55.17%) showed positive consanguinity (Group A) among which 18 females (56%) and 14 males (44%) presented with isolated dental anomalies. 12 females (66.6%) and 9 males (64.2%) in Group A showed significance with first cousin (P = 0.00204) whereas no significance was observed in other consanguinity type (P = 0.7287). Nonetheless, the overall frequency of isolated dental anomalies was slightly higher in Group A than Group B that was statistically significant (P = 0.0213). Conclusion: A positive correlation between dental anomalies among offspring of consanguineous marriages revealed such prevalence may be attributed to increased risk of recessive deleterious gene expression or defective allele carried to offspring.

Dentists in India feel hopeless as a fulltime academician: A national survey.

AIMS: Assess the relationship between job satisfaction and feeling of hopelessness among dental academicians. SETTINGS AND DESIGN: Cross sectional study was conducted among dental academicians across India through email and social media using a pretested questionnaire. METHODS AND MATERIALS: An Internet-based cross-sectional survey was conducted among dental academicians via social media and electronic mail (e-mail) throughout India. Demographics, credentials and job satisfaction across five dimensions (working conditions, pay and promotional potential, work relationships, use of skills and abilities and work activities) were rated on a 5-point Likert scale and a sense of hopelessness was assessed using Brief-H-Neg scale. The results were collected using self-reported Google forms. Bivariate and multivariate analysis were performed to identify the risk towards hopelessness, and the relationship between job satisfaction and hopelessness was assessed using student's t-test. RESULTS AND CONCLUSION: The mean hopelessness score among dissatisfied faculty was 8.5 and among satisfied was 5.6 (P < 0.05). Tutors, assistants and associate professors with salary of INR <50000/month were highly dissatisfied (P < 0.05), and those willing to quit reported significantly lesser hopelessness compared to no/maybe. Regarding job satisfaction, greater hopelessness was reported with poor work relationships, poor working conditions and poor pay and promotional opportunities (P < 0.05). Dental academicians in India are highly dissatisfied with their career as a full-time teaching faculty. Willingness to quit has a positive effect on hopelessness, depicting the stress faculties experience in institutions. Job satisfaction among academicians plays a vital role in the student's dental learning experience and dissatisfaction will have huge ramifications on the quality of dental education and future graduates in India.

Stereomicroscopic study on unsectioned extracted teeth.

INTRODUCTION: Age has been considered as a reliable marker for establishing the identity of a person in the field of forensic medicine. Teeth are useful skeletal indicators of age at death since it can survive for decades. Nondestructive methods ensure the evident preservation of dental hard tissues that reflect age changes from the cradle to the grave. Therefore, an attempt was made for estimating the age using the nondestructive method. AIMS AND OBJECTIVES: The aim of this study to assess whether physiological changes of the teeth allow possible correlation for accurate age estimation and to establish a graduation standard by microscopic observation for a better age correlation. MATERIALS AND METHODS: The study was carried on 209 teeth samples extracted for orthodontic treatment or periodontal diseases comprised both maxillary and mandibular teeth across different age groups. The assessment of these changes was carried out by well-established standard methods with some proposed modifications. RESULTS: Pearson correlation analyses revealed root dentin translucency with the highest correlation (r = 0.97) followed by periodontal ligament attachment (r = 0.95), root dentin color (r = 0.95), and attrition being the least correlated (r = 0.90). All the parameters taken for the study contributed to stepwise linear regression analysis (R = 0.98; P < 0.01) indicating a strongly positive relationship between age and the changes observed. A regression formula was obtained with mean error age difference ±1.0 years. CONCLUSION: The present study showed that extracted tooth is highly significant in identifying the age without being sectioned or further processed and also signifies the use of microscope for observation of these changes, thus reducing the errors of calibrating the age.
