The relationship of body heights, gender and anterior teeth dimensions in Malaysian population

To investigate the correlation between participants body heights and gender to the size particularly the widths and heights of anterior teeth of Malaysian population. The study samples consisted of 363 participants, including 67 males and 296 females, aged between 20 and 40 years from the Malaysian population. Digital impressions were taken of all six anterior teeth, from the right canine to the left canine and were imported into 3D software to measure tooth widths and heights digitally. Body heights of participants were recorded. Data was analyzed to see the correlation of the body heights of the participants to the measurements of the teeth using Pearson correlation coefficients and descriptive analyses for the differences of the widths and heights of teeth according to gender. Pearson correlation analysis showed that several tooth measurements positively correlate with body height, indicating an increase in tooth length, particularly in right lateral incisor height, right canine height, left central incisor height, left lateral incisor height, and left canine height as height increases. On gender differences, males showed to have wider and taller teeth than females, with a notable similarity in right lateral incisor width. This study concludes that tooth length increases with body height. Additionally, males exhibit larger tooth dimensions in both width and height across all six anterior teeth.
