Abstract


Background- In current generation, the patient tends to perceive more aesthetically driven smile and facial appearance, resulting in an increased interest in achieving optimal treatment outcomes. And hence, requirement of proper determination of appropriate dimension of maxillary anterior teeth has become more relevant. The relationship between facial measurements and tooth size provide guidance for selection of maxillary anterior tooth size.

MATERIALS AND METHODS- Thirty undergraduate students were enrolled in the study. They were divided into two groups.  Group A - contains 15 female and    Group B – contains 15 males. Two standardized colour photographs of each participant were made at the rest vertical dimension from a frontal and a profile view. The frontal parameters-bizygomatic width, interpupillary distance, intercanthal distance, interalar width, and intercommissural width were measured . The images were entered into image processing software (AutoCAD 2006; Autodesk, Inc) that allowed the photographs to be calibrated and facial parameters to be measured with digital caliper. Impressions of the maxillary arches were made with irreversible hydrocolloid impression material. The measurements of the teeth were made on a maxillary cast using digital sliding caliper. The width of each anterior tooth was recorded, and the combined width of the 6 anterior teeth on the straight line was calculated. The means and standard deviations from descriptive measurements were calculated and analyzed for face and maxillary anterior tooth ratios and correlations using statistical analysis.

RESULTS- No significant difference was found in tooth measurement among male and females. Mean overall facial measurement for in male was 54.01±31.76 and in female it was 54.13±32.23. By using students unpaired t test statistically no significant difference was found in overall facial parameter among male and female (t=1.21, p=0.23).

CONCLUSION: No consistent ratio was found between the facial dimensions and mesiodistal dimensions of the 6 maxillary anterior teeth among the males and females
