MORPHOFUNCTIONAL CHARACTERISTICS AND FEATURES OF SECONDARY DENTITION DEFORMITIES IN DIFFERENT AGE PERIODS

Abstract

Introduction. Currently, there is no consensus in the literature about the incidence of secondary deformities of the dentitions and their age characteristics. Thus, the question of the prevalence and features of secondary dentoalveolar deformities and anomalies of the dental arches in different age groups is relevant. Aim of the research. To study the prevalence, nature, features of secondary dentoalveolar deformities and anomalies of the dentition in different age groups. Materials and methods. For our study, we selected patients of different age groups who consulted the orthopedic dentistry clinic of the FSBEI HE Novosibirsk State Medical University of the Ministry of Health of Russia, as well as the 2–5 year students of the Faculty of Dentistry. Group 1 — 150 students aged 18–27 years, group 2 — 130 patients aged 30–45 years, group 3 — 140 patients aged 46–60 years. Results. In group 1, 150 second-fifth year students of the Faculty of Dentistry of the Novosibirsk State Medical University, aged 18–27 years, were examined. In 13 of them, the teeth were intact. Signs of secondary dentition deformities in patients of the first group were observed in 63 (42%) students. In group 2, 130 patients aged 30 to 45 years were examined, in 5 patients the dentitions were intact. Signs of secondary deformities of dentitions in the examined group 2 were observed in 71 (56%) patients. In group 3, 140 patients aged 46 to 60 years were examined, 18 of them had intact dentitions. In 122 of them, partial loss of teeth was observed. Signs of secondary deformities of the dentition in the examined group 3 were observed in 55 people (40%). Conclusion. The study shows that secondary dentition deformities can be observed both with preserved dentition in cases of multiple carious lesions of the occlusal surfaces of the teeth, anatomically incorrect restoration of the occlusal surfaces of the crowns of chewing teeth, or their contact surfaces after filling, and with partial loss of teeth in all age groups.
