Cusp of Carabelli in maxillary molars – A cross-sectional study

Author: NIVEDHA M, K. R. DON
Abstract: The cusp of Carabelli is a small additional cusp at the mesiopalatal line angle of maxillary first molars and rarely on second molars. Dental anatomical features are used primarily to determine a person's identity. The significance of a dental anatomical trait depends on its frequency of occurrence and distinctiveness in a given population. The aim of this study was to find out the presence of Cusp of Carabelli in Maxillary first and second molars among the chennai population. The present cross sectional study was conducted in May 2020. A total number of 100 participants were selected by convenient sampling predominantly among the Chennai population and were examined for the presence of cusp of carabelli. The statistical tests used were descriptive tests for determining the frequency and chi square tests for gender comparison. Statistical software used was SPSS software. P value less than 0.05 was considered as statistically significant and the confidence level was set at 95%. Cusp of Carabelli was present in 13% of maxillary first molars and was seen slightly higher in males (7%) than in females (6%). Cusp of Carabelli in 16 was 16% and in 26 was 10%. While in maxillary second molars, 5% in 17 and 2% in 27. This study showed that the cusp of carabelli was more predominantly seen on the right side than the left side. Cusp of Carabelli was slightly more in males than in females and more seen on the right side than the left side, which can be useful in developing a probabilistic model to identify individuals, mainly in Forensics.
