Purpose: The aim of the study was to assess the correlation between various anthropometric measurements of hand and the Vertical Dimension of Occlusion (VDO).
Methods: A total number of 500 dentate subjects were selected in a time span of six months for the study. The hand anthropometric measurements included the length of index finger, length of little finger, length of thumb and the distance between tip of thumb and tip of index finger for the left and the right hand. The distance between sub-nasale and base of chin was taken as control for assessing VDO. All measurements were recorded using a digital Vernier caliper with an accuracy of ± 0.01 mm.
Results: For males, the thumb length showed a highly significant correlation (Pearson correlation coefficient-0.258, p-value-<0.001) with the VDO. For females, the tip of thumb to tip of index finger length showed a highly significant correlation (Pearson correlation coefficient-0.306, p-value-<0.001) with the VDO. Accordingly regression formulae were derived.
Conclusions: In the absence of any pre-extraction records, thumb length in males and the tip of thumb to tip of index finger length in females can be used to derive the vertical dimension using the respective regression formulae reliably.
