OBJECTIVE: Introduction: The issues on identifying criteria for teeth aesthetic and teeth size evaluation regarding body constitutional characteristics are still remaining undeveloped. The aim of this study was to specify the peculiarities of teeth size in adolescents who were diagnosed with Angle's Class I malocclusion and display different somatotypes.
PATIENTS AND METHODS: Materials and methods: The study included 63 male and 66 female subjects diagnosed with Class I malocclusion by E. Angle classification (1906).
RESULTS: Results: It has been determined that the 33rd tooth in hypersthenic female individuals is of a greater mesiodistal size than in normosthenic and asthenic body types (p <0.05). Left maxillary incisor in hypersthenic individuals is of a larger size than in asthenic and normosthenic (p <0,05). The normosthenic male individuals have been found out to have significantly larger size of all canines than that in the females (p <0,05). The asthenic male adolescents compared with females of the same somatotype there has been revealed the difference in the size of the left mandibular canine (p <0.05). The hypersthenic male adolescents demonstrate an increase in the size of the lateral maxillary incisors and the first right premolar (p <0,05) compared with those in female individuals of the same somatotype.
CONCLUSION: Conclusions: Some peculiarities of mesiodistal size typical for adolescents with Angle's Class I malocclusion and their somatotypes should be taken into account in treatment planning and maintaining the stability of orthodontic treatment results.
