Abstract
PURPOSE: This work aimed to study the rate and quality of maturation of the mineral component of retained teeth 3.8, 4.8 and lower jaw fragment of a human in connective tissue dysplasia in different periods of postpartum ontogenesis. METHODS: The study involved 102 men (76 with connective tissue dysplasia and 26 without connective tissue dysplasia) divided into groups by age: 31-40, 41-50, 51-60 years. One tooth 3.8, 4.8 and a fragment of the alveolar part of the lower jaw in the projection of teeth 3.8, 4.8 0.5*0.5 cm in size were extracted from each examinee for medical indications. RESULTS: Low optical density values are observed at the age of 41-50 years, at the age of 51-60 years, indicating decreased mineral density and the presence of total areas of hypomineralization from the age 31-40 years in connective tissue dysplasia. At the age of 41-50, 51-60 years, at the boundary of connective tissue structures and periosteum, a pronounced sclerosis and deformation of delineation elements were observed; at the age of 31-40 years, the indicated changes were less pronounced. At the age of 31-40 years, the level of bone plate dissection has a local character, after 40 years, it has a generalized character. CONCLUSION: Progressive osteoporosis of the mandible and incomplete amelogenesis are an obstacle to the correct and harmonious teething of the lower wisdom teeth after the age of 30.
