STATE OF CERVICAL RESTORATION OF TEETH IN THE CONDITIONS OF ORTHODONTIC TREATMENT

Abstract

The aim of the study. Clinical evaluation of the state of direct photocomposite restorations of teeth in the cervical areas of teeth in persons with orthodontic pathology treated with fixed appliances. Research materials and methods. The condition of 123 direct photocomposite restorations in the cervical areas of teeth in 34 patients aged 26 to 44 years who were treated for orthodontic pathology for 1 year or longer using bracket systems fixed on the vestibular surfaces of the teeth of both jaws was examined. The term of operation of restorations made of various photocomposites before the start of orthodontic treatment was from 1 to 2 years. Clinical evaluation of restorations was carried out according to adapted criteria. Scientific novelty. It was found that 3 restorations (2.4% of the total number) were partially or almost completely destroyed, secondary caries was diagnosed next to them. The remaining 120 restorations (97.6%) retained their integrity. In the material of 1 restoration (0.8% of the number of wholes), a defect of anatomical shape was detected. Disruption of the marginal adhesion of photocomposites and marginal staining were established, respectively, in 28 (23.3%) and 31 restorations (25.8%). In 7 restored teeth (5.8%), signs of secondary caries were found with localization of the lesion exclusively on the periodontal wall. In 14 restorations (11.7%) a discrepancy in color was established. Absence of gloss was determined in 62 restorations (51.7%), increased roughness – in 33 restorations (27.5%). Conclusions. According to the results of the study, during the treatment of orthodontic pathology with fixed appliances in cervical tooth restorations, a large number of aesthetic deviations were established regarding the gloss and roughness of the surface of photocomposites, as well as violations of the marginal fit and the presence of marginal staining, which can be associated with insufficiently effective measures of individual oral hygiene and inadequate use of its means in conditions of the presence of fixed equipment.
