CLINICAL STATE OF DIRECT RESTORATION OF SIDE TEETH IN ORTHODONTIC PATIENTS

Abstract

Relevance. During long-term orthodontic treatment, there are favorable conditions for the development of dental caries and periodontal diseases.
 Aim of the study. Retrospective clinical evaluation of direct restorations of teeth in patients during treatment of orthodontic pathology with fixed appliances.
 Materials and methods. The condition of 227 direct photocomposite restorations of lateral teeth with localization on the occlusal and one of the contact surfaces and duration of functioning from 1 to 5 years was studied in 57 people who were treated with the use of fixed orthodontic equipment. Marginal fit, secondary caries and contact points were evaluated.
 Research results. In restorations with terms of 1-2 years, a violation of the marginal fit on the occlusal surface was found in 5 restorations (6.4% of their number with the given terms), on the vestibular and oral surfaces – in 7 (9%), in the area near the gums – in 10 restorations (12.8%). Secondary caries was detected on the vestibular surface in 2 restored teeth (2.6%), in the area near the gums – in 8 teeth (10.3%). There were violations of the contact point in 4 cases (5.1%). With terms of 4-5 years, in 3 restorations (10.3% of the number with these terms), violations of marginal fit were established on the occlusal surface, in 9 (31%) on the vestibular and oral surfaces, in 17 restorations (58.6%) – in the area near the gums. Secondary caries on the occlusal surface was found in 2 teeth (6.9%), on the vestibular and oral surfaces in 4 (13.8%), in the area near the gums – in 16 teeth (55.2%). Defects of the contact point were established in 19 cases (65.5%). Conclusions. In the conditions of orthodontic treatment with fixed equipment, the risk of developing disorders in photocomposite restorations in the area near the gums of the contact surfaces of the lateral teeth increases significantly.
