Abstract
OBJECTIVE: Significant association is exhibited between periodontal phenotypes and tooth crown morphology. The present study was planned to evaluate and correlate the facial and anterior teeth proportions among different facial types (FTs) based on gender in periodontally healthy patients. MATERIALS AND METHODS: Two hundred patients within an age range of 20-40 years were assigned equally into two groups based on gender. The extraoral and intraoral parameters of facial height (FH), facial width (FW), crown width (CW), crown height (CH), and intercommissural width (ICOW) were recorded on digitized photographs. From these values, tooth type (TT), FT, and facial index (FI) were calculated. RESULTS: The mean values of FI, CH, CW, and ICOW were greater while FH and FW lesser in females than males. The predominant presence of average FI (55%), mesoprosopic FT (58%), and triangular TT (51%) was observed in males, whereas in females, it was average FI (51%), mesoprosopic FT (55%), and triangular TT (51%). A2 tailed significant positive correlation was exhibited at (0.745) and (0.799) between TT and FI and (0.772) and (0.808) between TT and FT for males and females, respectively. Both the correlations were statistically significant (P < 0.05). CONCLUSION: The results suggest gender variability of the extraoral and intraoral parameters along with significant positive correlations between TT and FI and TT and FT. These extraoral and intraoral exhibits along with the periodontal phenotypes can be considered as critical aspects in smile designing procedures.
