“…Manning reported that the Asians tend to have a low index to ring finger ratios [27]. In our study, the mean index and ring finger ratio in male children is significantly lower than females in both hands similar to the observations in the earlier studies [21,22,27,31,[35][36][37] where on an average, males demonstrated lower digit ratios than females. Findings of our study with regard to sexual dimorphism of index and ring finger ratio in South Indian children are similar to those observed in the South Indian adult and adolescent population [21,22].…”

“…McIntyre et al [20] based on a study of hand radiographs indicate that relative digit lengths are sex-dimorphic in children. Index and ring finger ratio has been found to be a useful sex determinant in South-Indian adult and adolescent population [21,22]. The present research investigates the sexual dimorphism of index and ring finger ratio in South Indian children.…”

To investigate the sexual dimorphism of index and ring finger ratio in South Indian children. The index finger length (IFL) and the ring finger length (RFL) were measured in 350 subjects aged between 2 and 12 years using a steel measuring tape. The index and ring finger ratio was computed by dividing index finger length by ring finger length. The data obtained were analyzed statistically using SPSS, version 11.0. Mean RFL was greater than mean IFL in both males and females. The mean ring finger length was longer in males than females and mean index finger length longer in females than males. However, these sex differences observed for index and ring finger length were not significant in both hands. Statistically significant sex differences were observed from the derived index and ring finger ratio. The mean index and ring finger ratio was found to be higher in females than males. Significant correlation was found between age and index and ring finger lengths. Index and ring finger ratio however, did not show any significant correlation with age. This study suggests that among South-Indian children, the index and ring finger ratio of 0.97 and less is indicative of male, and a ratio of more than 0.97 is indicative of female sex. The ratio can be a useful sex indicator irrespective of the age of the individual.

Abstract:Purpose: The aim of this study was to find the correlation between vertical dimension of occlusion (VDO) with length of fingers and distance from hair line to nasion. Materials and Methods: A cross-sectional study was conducted on 400 dentate subjects comprising of 200 males and 200 females. Anthropometric measurements of VDO, length of index finger, length of little finger and distance from hair line to nasion were recorded clinically using digital vernier caliper. Correlation between VDO and length of fingers and distance from hair line to nasion was studied using Pearson"s correlation method. Results: VDO was significantly and positively correlated with all the parameters studied in females but not in males. In females, VDO had strongest correlation for length of little finger (r-0.550, p value<0.001) followed by length of index finger(r-0.413, p value<0.001), measured distance from hairline to nasion (r-0.294, p value<0.001) in the Gujarati populations. In males VDO was correlated with length of little finger(r-0.375, p value<0.001) but not with other 2 parameters studied. Conclusion: In females, pearson"s correlation for little finger is 0.550 and p value is less than 0.001, so length of liitle finger is the best parameter to predict VDO in females. Prediction of VDO through this method is reliable, and reproducible, this method is also simple, economic, and non-invasive; hence, it could be recommended for everyday practice. Abbreviations VDO= vertical dimension at occlusion.
