Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 9
Abstract
Aim: The aim of this study is to determine the gender differences for the size of deciduous molars in children of Jammu city. Materials and Methods: Of 893 children with age ranging from 6 to 11 years who visited the Department of Pediatric and Preventive Dentistry in Indira Gandhi Government Dental College, Jammu, from July 2016 to October 2016, 100 children were selected based on the inclusion criteria which were further divided into two groups. Group I included 50 males and Group II included 50 females. All the selected samples were initially subjected to oral prophylaxis, impressions were made with alginate, and casts were pored immediately with dental stone and the study models were prepared. The models thus obtained were finished and numbered for ease of identification. Electronic digital caliper calibrated to the nearest 0.01 mm was used to measure the mesiodistal and buccolingual dimensions of primary molars (both D and E) following the evaluation criteria. The evaluated result was then subjected to statistical analyses. Results: The mean dimension of upper first molar is 6.29mm, and in females, it is 6.27 mm. The mean buccolingual measurement for upper first molar in males is 8.77 mm and in females is 8.64 mm. The mean mesiodistal measurement for the upper second molars is 8.57 mm in males and 8.66 mm in females. Their mean buccolingual measurement was 9.71 mm in males and 9.70 mm in females. The mean dimension of lower first molar is 7.49 mm, and in females, it is 7.37 mm. The mean buccolingual measurement for lower first molar in males is 7.78 mm and in females is 7.46 mm. The mean mesiodistal measurement for the lower second molars is 9.52 mm in males and 9.27 mm in females. The mean buccolingual measurement in males was 9.11 mm and 8.78 in females. Conclusion: The dimensions of primary molars are slightly larger in males in comparison to females. The data about these measurements have an anthropological significance to differentiate various genders in different populations.
