Abstract
Aim: This observational study investigated the correlation of nail form to tooth form.Materials and Methods: Measurements of the length and width of left maxillary central incisor and the nail of the left hand’s forefinger of 110 subjects were taken with the help of a calibrated manual vernier caliper. The information obtained was statistically analyzed using Pearson’s correlation test.Results: A positive correlation existed between incisor length and nail length (P = 0.001), and incisor width and nail width (P = 0.001). Consistent relationships were also observed between these measurements.Conclusion: A definite correlation exists between nail form and anterior tooth form. It can be inferred that nail form can be considered amongst other parameters in determining the anterior tooth form.

Summary
Selection and replacement of the anterior teeth is one of the key determinants in the rehabilitation of the oral and stomatognathic system. In the absence of preextraction records, various parameters like intraoral anatomic landmarks, extra oral anatomical landmarks, geometric and mathematical measurements have been proposed as aids for effective artificial tooth selection. Williams classification[1] of facial form proposed in 1974 has been accepted as the universal method of determining anterior tooth form. Nails have been accepted as relatively good indices of the health of an individual. They have a high sensitivity to many internal and external factors. They have been used as a diagnostic tool in detecting recent health imbalances
