An In Vitro Study to Assess the Root Canal Morphology of Human Primary Molars Using Computerised Tomography

Background: A virtuous consideration of root canal morphology is required. Complications all through and after endodontic therapy are frequently caused by variances in the anatomy of root canals in primary teeth. The goal of present study was to determine the number and shape of root canals in primary incisors and molars, as well as the pertinency of cone beam computerised tomography (CBCT) in doing so.Material & Methods:On a total of 60 primary molars and incisors with complete root length, CBCT was used to assess the number of roots, number of canals, width of root canal at cementoenamel junction and middle-third, length and angulations of roots. The information was statistically analysed. Results:The CBCT revealed that 13 percent of mandibular incisors had bifurcation of the root canal in the middle third, while 20% of mandibular molars had two canals in the distal root. The distobuccal root canal diameter of maxillary molars and the mesiolingual canal diameter of mandibular molars were determined to be the smallest.Conclusions:Cone beam computed tomography (CBCT) is a comparatively new and effective technology that can be used in conjunction with conventional radiography to examine variations in root canal morphology in primary teeth.

To study problematic eating behavior and its association with early childhood caries among 36–71-month-old children using children eating behavior questionnaire

Context: Problematic eating behavior pattern prevalent in children can be a potential risk factor for Early Childhood Caries (ECC). Pediatric dentist must be vigilant to enquire about eating behavior pattern and guide parents comprehensively. Aim: The aim of this study is to find the association between problematic ECC among 36–71-month-old children. Setting and Design: A cross-sectional study was conducted in 2000 children from both the sex and various socioeconomic backgrounds. Methods: A questionnaire was made to assess the personal information and problematic eating behavior of the child using Children's Eating Behavior Questionnaire (CEBQ) which was filled by parents. Clinical examinations were performed on the date of questionnaire collection and caries diagnosis was done in the dentition status part of “WHO oral health assessment form 2013.” Statistical Analysis Used: The software used for the statistical analysis was SPSS (Statistical Package for the Social Sciences) software version 16.0. Results: The prevalence of ECC in the study sample was 42.6%. Out of eight domains into which problematic eating behavior was divided, domains Emotional Overeating (EOE), Satiety Responsiveness (SR), Slowness of Eating (SE), Desire to Drink, Food Fussiness, and Emotional Under eating were significantly associated with ECC. Conclusion: There is a positive correlation between problematic eating behavior and ECC; such behavior should be recognized at early stages and interrupted so that the risk of developing caries in permanent dentition could be prevented.
