Abstract

Objective: The aim of this study was to examine the quality of root canal fillings and their relationship with apical periodontitis (AP) in a selected Turkish population. Material and Methods: The cases in this study was formed of patients attending routine dental treatment at the Faculty of Dentistry, University of Birun. 1024 patients were examined with panoramic radiographs and 1780 endodontically treated teeth with present periapical radiographs. Endodontic treatment quality was evaluated by obturation length, density, taper quality and iatrogenic errors. Presence of AP was analysed according to Ørstavik’s periapical index (PAI). The chi-square test was used for statistical analyses. Results: Statistically significant relationship was found between both the tooth type and location with obturation quality (p: 0.000; p < 0.05). Obturation quality of maxillary and mandibular molars are significantly less than the other tooth types in the same location. Apical periodontitis were noticed in 740 teeth (41.6%). Inadequate obturation quality was found to be significantly effective on the periapical status of tooth types both in maxilla and mandible (p < 0.05). Conclusion: The frequency of inadequate root canal obturations of endodontically treated teeth of the selected Turkish population was high, especially in molar teeth and women. Even though radiographic obturation quality is not the only success criteria in endodontic treatment, it is still one of the most important criteria regarding the positive correlation of “inadequate” obturations with AP.KEYWORDSPeriapical periodontitis; Radiography; Root canal obturation; Root canal theraphy.

Highlights

Apical periodontitis (AP) is an inflammatory status of the periapical tissues that might evolve if microorganisms are introduced into the pulp tissue [1]
The main inclusion criteria in the study was the availability of a panoramic radiograph and a periapical radiograph taken from the section of the endodontically treated tooth
Root canal obturation length and density were examined on Apical periodontitis in relation to radiographic quality of endodontic treatment in a selected adult Turkish population: a cross-sectional study the basis of European Society of Endodontology guidelines [19]

Summary

Introduction

Apical periodontitis (AP) is an inflammatory status of the periapical tissues that might evolve if microorganisms are introduced into the pulp tissue [1]. Different studies indicated that the prevalance of root canal treatment ranged from 22% to %72 and most of AP cases appear to be located in formerly endodontically treated teeth [2,3,4]. The existence of AP in root canal treated teeth after a certain time might be recognized as evidence of endodontic treatment failure. A descriptive approach with a cross-sectional study model is generally used in studies of the success and quality of root canal therapy, too [10]. Data from these studies might be very beneficial in the assessment and designing of dental education as well as in dental care planning [11]
