RETROSPECTIVE ANALYSIS OF EFFICACY IN APPLYING MINERAL TRIOXIDE AGGREGATE AND CALCIUM-CONTAINING AGENTS FOR APEXIFICATION
Introduction. The algorithm for choosing a method of treatment for permanent teeth with incompletely formed root, described in the study of Shabahang S. (2013), involves the procedure of apexification in cases of irreversible pulpitis and pulp necrosis, and convalescent therapy in cases of diagnosis of recurrent pathological phenomena in the pulp structure. The aim of the study was to conduct a retrospective analysis of the effectiveness of applying mineral trioxide aggregate and calcium-containing agents in order to carry out the apexification procedure according to the data of previous studies. Materials and methods. Relevant publications were searched by Google Scholar search (https://scholar.google.com/), Pubmed databases (https://www.ncbi.nlm.nih.gov/ pubmed /) and ScienceDirect (https://www.sciencedirect.com/). Results. The data available to date are of varying evidence and do not confirm the fact that the mineral trioxide aggregate is more clinically effective than calcium hydroxide for the purpose of apexification in cases of endodontic treatment of incomplete root formation. However, a significant advantage of mineral trioxide aggregate is the possibility of one-stage root canal formation with subsequent permanent obturation of the root canal after complete curing of mineral trioxide aggregate. Conclusion. The reports analyzed are characterized by variability of designs and the use of different approaches to assess the formation of the apical part of the tooth; moreover, most publications do not evaluate the initial level of root formation, which can potentially affect the success of the manipulation. The lower success rate of calcium-containing aids for apexification reported in a number of studies is justified by the prolongation of treatment, during which there is a tendency for patients to miss the check-ups and to drop out of the generated study sample during the relevant monitoring period. In order to formulate appropriate clinical recommendations, it is necessary to ensure that the baseline and treatment outcomes are referenced to a unified system of criteria for interpretation of all quality indicators of apexification achieved.
