Background: Pre-eruptive intracoronal radiolucency (PEIR) poses a challenge to paediatric dentists as it cannot be clinically detected. Aim: To estimate the prevalence and coexisting factors of PEIR in permanent teeth of children and adolescents in western Tamil Nadu, India. Design: This cross-sectional study assessed 5012 digital panoramic radiographs of children and adolescents below 14 years of age obtained from private digital imaging centers, dental clinics, and dental colleges located in five districts of western Tamil Nadu. The prevalence and PEIR and its coexisting factors were assessed by two independent calibrated investigators. Data were analyzed using the chi-square test.Results: The subject prevalence and tooth prevalence of PEIR were estimated to be 3.2% and 0.4%, respectively. Maxillary canines and mandibular premolars were commonly involved. Majority of the lesions were limited to less than onethird of dentin thickness (74%) and distal aspect of the crown (45.1%). Ectopic positioning (9.3%) and dental caries in the preceding primary tooth (9.9%) were the most common coexisting factors. Conclusion:Pre-Eruptive Intracoronal Radiolucency defects were commonly seen in maxillary canines, mandibular premolars, and distal aspect of the crown involving less than one-third dentin thickness. Ectopic positioning and caries in primary teeth were commonly seen along with the PEIR defects.
Introduction Dental profession is one of the most stressful healthcare occupations. Paediatric dental postgraduates face multifaceted challenges in their everyday practice. This study aimed to determine the sources of stress amongst paediatric dental postgraduate students in India using a mixed‐method approach. Materials and Methods A sequential mixed‐methods approach was employed. In the quantitative phase, a cross‐sectional web‐based questionnaire survey was conducted amongst paediatric dental postgraduates in India using the “Google Forms application” link. Based on the Dental Environment Stress (DES) questionnaire, the stress PACT questionnaire which includes 35 items was framed and validated. This validated questionnaire was used in the survey. In the qualitative phase, one‐on‐one, semi‐structured telephone interviews were conducted amongst 12 postgraduates. Results A total of 422 participants took part in the quantitative survey. Academic and specialty‐related domains were found to be the significant causes of stress amongst the five domains (p < .001). The top three stressful factors were as follows: getting an ideal case for clinical exams (68.2%), financial resources for conferences, dissertation, short studies and publications (53.2%) and fear of unemployment after graduation (52.3%). Based on qualitative interviews, four themes were derived, namely choice of paediatric dentistry, postgraduate life experience, stress management and expected changes in postgraduate life. Conclusion Psychological well‐being of the student is an important factor that influences the overall performance of students. Identifying the stress factors and using appropriate coping strategies can help postgraduates achieve personal, academic and professional success.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
