Radiological assessment of the quality of root canal fillings in teeth endodontically treated at students’ practical sessions

Abstract

Introduction The main goal of obturation is prevention of reinfection of the root canal system and consequently appearance of periapical lesion. Epidemiological studies have confirmed high prevalence of periapical lesions in endodontically treated teeth with inadequate root canal fillings. The aim of this study was to assess the quality of root canal fillings in teeth treated at students' practical sessions. Iatrogenic errors during endodontic interventions were also assessed. Methods Two hundred dental records of the patients treated by students in the study program Dentistry at the School of Medicine in Foca during the academic year 2010/2011 were randomly chosen. The length and homogeneity of the fillings or the presence of iatrogenic errors were recorded. A root canal filling was considered adequate if it had correct length and homogeneity in the absence of iatrogenic errors. Two students' curricula V 1 and V 2 were evaluated for the treatment outcome. Results Out of 128 endodontically treated teeth, adequate length of the canal filling to the physiological apex was observed in 57% of teeth, homogeneity in 78.9%, while both of these criteria were satisfied in 66 teeth (51.6%). Better quality of root canal fillings was achieved by students of the study curricula V 2 and the difference between these two programs was significant (p<0.05). Better quality of root canal fillings in both study programs was recorded for incisors and canines as compared to premolars. Conclusion The quality of endodontic treatment performed by students was considered adequate in 51.6% of cases. The type of curriculum for endodontic course had a significant impact on the quality of endodontic treatment performed by students.

Prevalence of the root canal treatment errors and its related factors in patients treated by undergraduate dental students

“…In this study, similar to Kulic et al (2011), multi root teeth which had error during treatment, even in one canals, was considered as unacceptable treatment. Unal et al (2011) reported highest prevalence of acceptable treatment in anterior teeth was 90.1% and the least prevalence was reported in 46.6% molars.…”

“…Kelbauskas et al (2009) reported that 5.42% had overfi lling which was compatible with this study. Kulic et al (2011) reported3.3% overfi lling which this low prevalence can be due to less numbers of their samples (306 canal). Er et al (2006) reported 13% overfi lling cases and Khabbaz et al reported 22.6% overfi lling.…”

“…Er et al (2006) reported that 48.8% fi lling had inadequate density. In addition, Khabbaz et al (2010) stated that 33.5% fi lling had inadequate density and Kulic L et al (2011) in 25% and Dadresanfar et al reported that 29.2% fi lling had inadequate density. Statistical difference of these results with mentioned studies can be stemmed from increase of assistants and professors' numbers and continuous study of patients during treatment by professors via providing constancy control radiographies during obscuration which reduces prevalence of errors during canal fi lling.…”

“…Epidemiologic studies introduced errors in mentioned procedure as the main reason of treatment failures and imposing higher costs (Lynch 2006;Mozayeni 2006;Yousuf, 2015). It has been indicated that acceptable RCT refers to treatments in which root fi llings terminate within 2mm of the radiographic apex and that are of adequate homogene density and without void from crown to apical area (Bramanten 1987;Kulic 2011). Applied method for studying quality of root treatment is assessing PA Radiographs that are provided before and after root treatments, radiographically (Kelbauskas 2009;Mosby Co. 2009).…”

Evaluation of the Quality of Endodontic Treatment among a Sample of Jordanian Population : A Radiographic Study

“…(3) Therefore, in order to evaluate the endodontic status, numerous studies have focused on the prevalence and quality of root canal treatment. (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) Several reports indicated that the prevalence of root canal treatment varies from 2.1% to 23.4% (15)(16)(17)(18)(19)(20)(21) and increases with age (22)(23) and the prevalence of apical periodontitis varies from 1.6% to 27.0% (1,4,5,7-10, [15][16][17][18]20,[22][23][24][25][26] Radiology is especially important for diagnosis in the detection of periapical lesions, and to assess treatment success including post-treatment healing. (1,4,5,7,9) The interpretation of radiographs is the only method that can be used to evaluate periapical health in an epidemiologic study.…”
