“…Furthermore, the results also showed that the students performed root canal treatments in both single and multirooted teeth. The findings are similar to those reported by Lynch & Burke (2006) who assessed the technical quality of root canal treatment in single-rooted teeth in Ireland and to those of Donnelly et al (2016) who used similar canal preparation technology for root canal treatment to the ones used in the current audit. Results of similar clinical audits, however, from other UK dental schools have found acceptable root filling rates as high as 80% and as low as 13%, respectively (Hayes et al 2001, Pettigrew et al 2007.…”

“…different whether performed on anterior or posterior tooth and this may be related to the use of rotary NiTi instrumentation as shown by Donnelly et al (2016) where the treatment outcome for posterior teeth has improved with the introduction of such technology. However, it is also likely that the limitation of periapical radiographs in assessing the quality of root fillings in posterior teeth may have overestimated the outcome compared to anterior teeth.…”

Aim To evaluate radiographically the technical quality of root fillings performed by undergraduate dental students and to assess whether students were exposed to an appropriate endodontic case mix during their clinical training. Accepted ArticleThis article is protected by copyright. All rights reserved. School at Queen's University Belfast, UK. Two final year dental students were trained and calibrated to evaluate post-operative intraoral periapical radiograph of completed root canal treatments using specific assessment criteria. Data was presented as frequencies, percentage and mean  standard deviation (SD). Comparisons of treatment outcomes between groups (posterior and anterior teeth) were calculated using Fisher's Exact Test and the level of significance was set at p<0.05. Intra-and inter-examiner reproducibility was assessed by Kappa statistics.Results A total of 222 teeth and 381 canals were assessed and of those 253 (66%) of the root fillings were found to be acceptable in all the assessment parameters namely, taper, length and lateral adaptation of the root filling. Sub-analysis of individual root filling parameters revealed that 372 canals (97%) exhibited good taper, 275 canals (72%) were considered to be of an appropriate length, with 89 canals (23%) found to be underfilled and 17 canals (5%) overfilled. Overall 346 (91%) of canals had good lateral condensation. Students treated both single and multi-rooted teeth and there was no significant association between tooth type and the quality of root filling provided (p>0.05). ConclusionIn the majority of the teeth treated by undergraduate students at Queen's University Belfast, the technical quality of the root filling was acceptable and students were exposed to an appropriate case mix for endodontic training.

“…Previous studies have used radiographic assessment of the technical quality of root fillings as criteria to audit the overall quality of treatment conducted by undergraduate students in various populations (Eleftheriadis & Lambrianidis , Donnelly et al . ). The technical quality parameters mainly assessed were the length of the root filling material in relation to the radiographic apex, the density of the filling material (i.e.…”

“…Auditing the work of undergraduate students regularly ensures that an adequate standard of treatment is being delivered (Donnelly et al . ) as there is no minimum level of knowledge or skill‐based input for dental students that can be deemed acceptable (European Society of Endodontology ). Moreover, current undergraduate students will be the clinicians of the future.…”

Technical quality of root canal treatment performed by undergraduate students using hand instrumentation: a meta‐analysis

Ribeiro DM, R eus JC, Felippe WT, Pacheco-Pereira C, Dutra KL, Santos JN, Porporatti AL, De Luca Canto G. Technical quality of root canal treatment performed by undergraduate students using hand instrumentation: a metaanalysis. International Endodontic Journal, 51, 269-283, 2018.The technical quality of root canal treatment (RCT) may impact on the outcome. The quality of education received during undergraduate school may be linked to the quality of treatment provided in general dental practice. In this context, the aim of this systematic review was to answer the following focused questions: (i) What is the frequency of acceptable technical quality of root fillings, assessed radiographically, performed by undergraduate students? (ii) What are the most common errors assessed radiographically and reported in these treatments? For this purpose, articles that evaluated the quality of root fillings performed by undergraduate students were selected. Data were collected based on predetermined criteria. The key features from the included studies were extracted. GRADE-tool assessed the quality of the evidence. MAStARI evaluated the methodological quality, and a meta-analysis on all studies was conducted. At the end of the screening, 24 articles were identified. Overall frequency of acceptable technical quality of root fillings was 48%. From this total, 52% related to anterior teeth, 49% to premolars and 26% to molars. The main procedural errors reported were ledge formation, furcation perforation, apical transportation and apical perforation. The heterogeneity amongst the studies was high (84-99%). Five studies had a high risk of bias, eight had a moderate risk, and 11 had low risk. The overall quality of evidence identified was very low. The conclusion was that technical quality of root fillings performed by undergraduate students is low, which may reveal that endodontic education has limited achievement at undergraduate level. A plan to improve the quality of root fillings, and by extrapolation the overall quality of root canal treatment, should be discussed by the staff responsible for endodontic education and training.

To compare the technical quality of root canal treatment (RCT) depending on the incidence of procedural errors performed by undergraduate students using nickel-titanium reciprocating and conventional hand instrumentation techniques, and to assess the impact of case difficulty and localization of the teeth (maxillary or mandibular molars).Methods: Dental records and periapical radiographs of molars that were treated with either hand or reciprocating WaveOne (WO) instruments were evaluated retrospectively. The technical quality of RCTs, the incidence of ledge formation, perforation, instrument fracture, overinstrumentation, underfilling, overfilling, inadequate root canal filling, and the effects of case difficulty and tooth localization were compared using the chi-square test with a significance of 5% (α = 0.05).Results: While overinstrumentation was more frequent in the WO group (247 teeth), the incidence of inadequate root canal fillings was higher in the hand instrumentation group (245 teeth) (p < 0.01). No significant difference was observed in the incidence of other procedural errors (p > 0.05). The number of teeth with acceptable technical quality in preparation and obturation was 172 (69.6%) in the WO group, whereas it was 142 (58%) in the hand instrumentation group, presenting a significant difference between the instrumentation techniques (p < 0.01). Higher technical quality rates were observed with WO instrumentation in the high difficulty category and in maxillary teeth (p < 0.01). Conclusion:Higher technical quality in preparation and obturation can be achieved with WO reciprocating instruments and file-matched greater tapered gutta-percha cones. No significant difference was observed between the groups in the incidence of procedural errors except for overinstrumentation and insufficient root canal filling. WO instrumentation and obturation with file-matched greater tapered gutta-percha cones provided better technical quality in the high difficulty category and in maxillary teeth.

A re‐audit of the technical quality of undergraduate root canal treatment after the introduction of new technology and teaching practices

Abstract: Changes to endodontic teaching practices significantly improved the technical standards of undergraduate root filling in multirooted teeth. The regular auditing of undergraduate teaching practice is necessary to inform current teaching, instigate change and improve standards.
