Abstract

Objectives: The objective of this study was to find out if exposure since birth to a naturally fluoridated drinking water supply has any impact on sexual dimorphism as assessed by measurement of the mandibular canine index. Materials and Methods: Children from two areas were selected for the study: Aaspur (Dungarpur) and Chikhalwas (Udaipur), which are high-fluoride (4.0 ppm) and optimal-fluoride (1.1 ppm) areas, respectively. Data were obtained from 145 school children in the 14-15 year age-group. Of these, 75 were from the high-fluoride area and 70 were from the optimal-fluoride area. Alginate impressions of the mandibular arch were made for all subjects and these were poured immediately in type IV dental stone to minimize dimensional shrinkage. The parameters considered were canine width, intercanine distance, and mandibular canine index. All the measurements were recorded using a modified vernier calipers and divider. Data were statistically analyzed using SPSS/PC+ (SPSS Inc., Illinois, USA). Results: Significant differences were found between optimum-fluoride and high-fluoride areas in all the considered parameters except for the right canine width and the intercanine distance. Standard mandibular canine index is a quick and easy method for determining sex. Conclusion: Fluoride level does not have any particular impact on assessment of sexual dimorphism using the mandibular canine index.
