RELATIONSHIP OF THE HORIZONTAL FACIAL DIMENSIONS WITH THE WIDTH OF PERMANENT MAXILLARY ANTERIOR TEETH
To determine the correlation between the width of permanent maxillary anterior teeth and the horizontal facial dimensions. This cross-sectional descriptive study included 82 participants. The inclusion criteria were adult patients of both genders, with complete set and good alignment of maxillary anterior teeth. Data were collected for age, gender, facial dimensions, and dental widths. Vernier calliper was used to measure the mesiodistal width [MDW] of the maxillary anterior teeth and facial dimensions (inter-pupillary distance [IPD], inter-canthal distance [ICD], and bi-zygomatic width [BZW]). The student t-test was used to compare facial and dental measurements between genders, while the Pearson correlation test was used to determine the relationship between dental and facial dimensions. The mean age of the participants was 24.54±4.94 years, with 44 (53.66%) of them being females. Statistically, dental and facial dimensions were larger in males than in females (p<0.05). There was a moderately positive and significant correlation between the central incisor and IPD (r=0.54, p<0.001), as well as the lateral incisor with IPD (r=0.4, p<0.001), and the canine with IPD (r=0.54, p<0.001). The correlation between the central incisor and ICD was high, positive, and significant (r=0.71, p<0.001), and similar results were found for the canine with IPD (r=0.71, p<0.001). The correlation between dental widths and BZW was moderately positive and statistically significant. Facial parameters can be used to predict the maxillary anterior tooth sizes.
