ROOT CANAL MORPHOLOGY SYSTEM ANDENDODONTIC IRRIGANTS USED FOR TREATMENTIN CHRONIC APICAL PERIODONTITIS

Abstract

Introduction. Chronic apical periodontitis develops as a consequence of complications of pulpitis and affects periodontal
tissues. And also, it ranks third in incidence among oral diseases, being the cause of tooth extraction and various
complications. One of the main reasons for the occurrence of disease is the lack of knowledge of the features of the anatomy
of root canals and the peculiarities of drug treatment in endodontic treatment, which is considered in this review article.

The aim is to analyze the current literature on the study of the morphology of root canals depending on the population
and the effect of drugs for drug treatment on microbial biofilm, a lubricated layer in endodontic dental treatment in chronic
apical periodontitis.
Search strategy. The literature search was carried out using PubMed, GoogleScholar, e-library, Cochrane library
databases. The search was performed by keywords: "morphology of root canals", "chronic apical periodontitis", "irrigation of
root canals", "additional canals", "microbial biofilm".
Results and conclusions.The study of the number and possible variations of additional channels, depending on the
affiliation of the tooth and possibly the ethnic race, will help to improve and properly plan the treatment of patients with HAP.
Most studies of the effects of irrigants on biofilm and the lubricated layer are carried out ex vivo, in vitro and intermediate
results are evaluated. It is necessary to reconsider the priorities of research in this area and to study more deeply the
penetration of irrigants, their effect on biofilm, dentine tubules and long-term treatment results.
