Abstract: (3370 Views)
Background and Aim: Considering the importance of teeth dimensions in their adequacies and aesthetics, their significant racial differences, and various statistics regarding the dimensions of symmetrical teeth in previous articles, we aimed to evaluate the dimensions of symmetrical permanent teeth on two sides of the maxillary and mandibular dental arches and related factors in different occlusions of students and patients of Islamic Azad Dental University of Tehran.
Materials and Methods: This cross-sectional study was conducted on 210 people. A dental cast was made for each individual. The mesiodistal, labiolingual, and occlusogingival dimensions of the clinical crowns were measured using a caliper with the accuracy of 0.1 mm along with their adaptation and symmetry on two sides of the maxillary and mandibular dental arches and related factors. Data were analyzed using Chi-square test.
Results: 67.1% of the patients were females and 32.9% were males. There were 69.3% symmetric and 30.7% asymmetric cases; there were no significant differences in terms of the dimensions, gender, and jaws (P<0.8). Regarding teeth types and variations in maxillary and mandibular central incisors, symmetrical values were 10.3%, while non-symmetrical values were 31.3%. Asymmetrical values in central incisors of both dental arches were significantly greater than symmetrical values.
Conclusion: It seems that on the left and right sides of both dental arches of permanent teeth in both genders, symmetrical values are greater than asymmetrical values. Asymmetrical values in central incisors of both arches were significantly greater than symmetrical values.
