Abstract

Aim: To assess the relationship of the maxillary intercanine line to incisive papilla in the South Indian states of Karnataka, Kerala, and Tamil Nadu. Materials and methods: Dental casts obtained from impressions of 90 dentate subjects were used. The maxillary occlusal plane was standardized using a novel device, and the distance between canine tips and the anteroposterior border of the incisive papilla was established. After the division of the incisive papilla into the anterior, middle, and posterior third, the relationship between the intercanine line and the incisive papilla was established using a novel method. Data was analyzed statistically using the Statistical Package for the Social Sciences (SPSS) software. Results: The mean intercanine distance and anteroposterior length of incisive papilla were found to be 35.45 ± 1.84 mm and 7.84 ± 1.30 mm, respectively. The results of the analysis of variance (ANOVA) test showed no ethnic differences. The intercanine line passed through the middle third of incisive papilla in 60, 63.3, and 56.7% of subjects from Karnataka, Kerala, and Tamil Nadu, respectively. The results of the Chi-squared test showed no gender difference. Conclusion: It can be concluded that the intercanine line fells within the middle third of the incisive papilla in the majority of the study population, inferring that there is no variation between these different ethnic groups. Clinical significance: Incisive papilla may be used as a biometric guide during teeth arrangement in complete denture prosthesis in the absence of preextraction records.
