CLINICAL RESULTS OF THE STUDY OF THE CONDITION OF DENTAL RESTORATIONS

The article is devoted to optimization of clinical approaches to the formation of enamel edges in Black class I caries cavities on the occlusal surface of posterior teeth by applying a two-stage algorithm of direct restoration using light-activated composite resin materials.Formation of an enamel bevel in such cavities usually requires additional removal of intact dentin and enamel.Gentle preparation with preservation of these hard tissues is possible by applying the developed two-stage algorithm of direct restoration with strengthening of enamel edges with light-activated composite resin.Clinical evaluation of direct restorations of posterior teeth performed using different approaches to the formation of enamel edges was carried out at 18 and 24 months.According to clinically significant assessment criteria, which concerned the marginal fit of the material to the enamel, marginal staining at the restoration border and secondary caries, in the case of formation of enamel edges in cavities of the indicated localization using traditional approaches, 12 violations were detected in 10 restorations (23.3%) within 18 months, and 16 violations in 13 restorations (40.6%) within 24 months; when using the two-stage algorithm, significantly fewer complications were detected within the given time periods, in particular, 7 violations in 6 restorations (11.1%) and 8 violations in 7 restorations (15.2%), respectively.The results obtained in the clinical study indicate certain advantages of the developed two-stage algorithm for direct restoration of posterior teeth with Black class I cavities on the occlusal surface using light-activated composite resin materials.
