    Background: Esthetic appearance of the maxillary anterior teeth to large extent influences facial esthetics. In case of partially or completely edentulous dentition or implant-supported prosthesis determining length of the maxillary central incisors is quite challenging due to consideration of esthetic factors such as available interocclusal space and amount of the tooth that should be visible and that which should not be. Aim: The aim of the study was to evaluation of correlation between bizygomatic width and nail size as a guide in teeth selection. Materials and Methods: Twenty subjects were selected for the study. Measurement of cervical incisal height of maxillary central incisors. Mesiodistal dimension of maxillary central incisors was measured at its greatest diameter with divider and ruler. Length and width of maxillary central incisor assessed using Berry’s and H pound formula for teeth selection were used as standard reference values. Results: The mean of length of the index finger length in 0.99 and index finger width is 0.95. The mean of length and width of ring finger is 1.02 and 1.05, respectively. Table 1 shows correlation between index fingernail width and mesiodistal dimension of maxillary central incisors with P = 0.0479 which is statistically significant. Table 2 shows correlation between ring fingernail width and mesiodistal dimension of maxillary central incisors with P = 0.6941) which is statistically insignificant. Conclusion: In anthropometric system of teeth selection, various anatomical entities such as maxillomandibular relations, contour of the residual ridge, vertical distance between the ridges, lips etc. which are used as guides to select teeth, fingernail size can also be used as a guide for teeth selection. Furthermore, variation in correlation between nail size and bizygomatic width among various populations can be assessed. From our point of view, to achieve high degree of accuracy, large sample size of participant from different ethnic group can be recruited into the study.
