Abstract
Endodontic treatment is accompanied by the loss of a significant amount of tooth crowns, which leads to a significant decrease in their strength characteristics. The restoration of endodontically treated teeth, as a rule, is carried out by the direct method, however, a unified approach regarding direct or indirect restoration has not yet been determined. The aim – retrospective analysis of the clinical condition of direct restorations of endodontically treated teeth. Materials and methods. 284 patients aged 25 to 60 years were examined; they studied the state of 888 previously performed direct restorations of the anterior and posterior teeth after endodontic treatment in a period of 2 to 10 years. Restorations were evaluated according to the adapted clinical criteria “integrity of the restoration”, “marginal fit of the material”, “marginal staining”, “anatomical shape”, “colour correspondence for the restoration”, “roughness of the surface of the material”, as well as the criterion “condition of the contact point” for located on the contact surfaces of the teeth of the restorations. Results. Of the 888 examined direct restorations, 760 restorations (85.6±1.18 %) were located in the posterior teeth, with 562 restorations in the molars (63.3±1.62 % of the total) and 198 in the premolars (22 , 3±1.40 %), and 128 restorations (14.4±1.18 %) were detected in the anterior teeth, while in the incisors - 80 restorations (9.0±0.96 %), in the fangs – 48 (3.5±0.76 %). 720 restorations (81.1±1.31 %) were made from photocomposite materials, 97 restorations (10.9±1.05 %) from chemical curing composites, 71 (8.0±0.91 %) from glass-ionomer cements . The most common violations were colour mismatch – in 511 restorations (57.5±1.66 %), marginal staining - in 470 restorations (52.9±1.68 %), surface roughness - in 357 restorations (40.2±1.0, 65 %). More often than others, in the reconstructions of their photocomposites and glass ionomers there was a colour mismatch, and surface roughness for chemical composites. Conclusions. For direct tooth restoration after endodontic treatment in 81.1±1.31 % of cases, photocomposite materials are used, less often chemical curing composites and glass ionomers. Of the violations of such restorations, the most frequent are colour mismatch, surface roughness and edge staining.

In the course of assessing the state of direct restorations, their localization, as well as their belonging to a particular class of cavities according to Black, was studied, restorations were assessed using the adapted clinical criteria “restoration integrity”, “marginal fit of the material”, “marginal staining”, “anatomical shape”, “color correspondence of the restoration”, “surface roughness of the material”, as well as according to the additional criterion “state of the contact point”, which was used in case of restoration of the contact surfaces of the teeth [11]
Summary
Or poor-quality treatment of dental caries, as you know, leads to the development of complications, as a result of which endodontic intervention or tooth extraction becomes necessary. The inevitable task of adequately restoring the crown of the teeth arises. Removal of hard tissues pathologically altered due to the carious process and creation of free access to the root canal mouths for their full instrumental (2020), «EUREKA: Health Sciences» Number 4 processing and obturation, often the search for additional canals or removal of the material of the previous restoration, if necessary, repeated endodontic intervention leads to a significant decrease in the strength characteristics of such teeth [3, 4]. The weakened and thinned walls of the cavities after endodontic manipulations, especially in the teeth of the lateral group, need hardening in order to withstand high chewing pressure
