Outcome of nonsurgical endodontic treatment: A 5-year recall

Abstract

Background: Prognosis of nonsurgical endodontic treatment has been extensively studied over the last decades; however, the data obtained is insuffi cient. The purpose of this study was to retrospectively analyze the outcomes of initial endodontic treatment, and tooth retention over 5 years. Materials and Methods: In this study, the treatment database of the King Khalid University Dental Clinics (KKUCD) is used to identify patient's undergone nonsurgical endodontic treatment in the year 2009. 779 patients were treated by students, interns, and specialists in KKUCD. 205 patients (217 teeth) were recalled and examined their teeth presence (retention), endodontic lesion healing status, and medical history status. Results: Among the 217 teeth, 208 were retained and 9 were extracted in 5 years. The 217 teeth, 34 treated by specialists, 90 by interns, and 93 by students. The 9 extracted teeth were 3 treated by specialists, 1 by interns, and 5 by students. The 9 extracted teeth were 4 maxillary premolars, 2 maxillary molars, 2 mandibular premolars, and 1 mandibular anterior. Using Chi-square tests, survival endodontic cases which had uncertain to successful endodontic healing are 27 treated by specialists, 86 by interns, and 75 by students. There was a signifi cant diff erence (P = 0.000) in endodontic success and survivability between the normal medical status and insulin-dependent diabetes patients. Conclusions: Within the limitations of this study, the survivability of nonsurgical endodontic treatment is very highly predictable 90%. Prosthodontics consideration is highly important since all extracted teeth in the study were not crowned. Nonsurgical endodontic treatment within insulin-dependent diabetes patients has fair to poor prognosis, which shows a less rate of success in comparison to other compromised patients.
