ABSTRACT This study evaluated the radiographic technical quality of preclinical and clinical root canal fillings (RCF) performed by undergraduate students on single-rooted teeth. Two independent calibrated endodontic specialists evaluated 94 preclinical radiographs (group 1) and 96 clinical radiographs (group 2). The apical length of each RCF was categorized as acceptable (0-2.0 mm short of the radiographic apex), underfilled (2.0 mm or more short of the radiographic apex) and overfilled (extruded beyond the radiographic apex). Inadequate or adequate homogeneity were also evaluated based on the presence of voids and the uniform density of the RCF. Cohen's kappa and Chi-square tests (p < 0.05) were used for statistical analysis. The interexaminer agreement level was almost perfect (>0.80). Approximately 80% of RCF had acceptable length in both groups, with no significant differences among them (p > 0.05). The rate of adequate homogeneity was higher in Group 2 when compared with group 1 (p < 0.05). Overall, the quality of RCF was satisfactory with better homogeneous seal at the clinical level.

Aim. The aim of this study was to evaluate the radiographic technical quality of endodontic treatment performed by undergraduate students at the School of Dentistry, Faculty of Medicine, University of Novi Sad, Serbia.Materials and Methods. Electronic records of 220 patients treated by final-year undergraduate students during the school year 2011/2012 were examined, and the final sample consisted of 212 patients, 322 teeth, and 565 root canals. The criteria for overall radiographic adequacy of root canal fillings were defined as the presence of adequate length and density and absence of iatrogenic errors (ledge, fractured instrument, untreated canal, and apical transportation). Chi-square test was used to determine statistical significance between different parameters.Results. Adequate root canal fillings were found in 74.22% of the teeth. The percentage of root fillings with adequate length and density was 89.73% and 92.6%, respectively. Fractured instruments and ledges were present in 16 root canals (2.8%), while the presence of missed canal and apical transportation was observed in 2 cases, each (0.3%).Conclusions. Overall, the technical quality of root canal fillings performed by undergraduate students was satisfactory.

The aim of this study was to evaluate the quality of root canal filling performed by undergraduate students at the Federal University of Espirito Santo (UFES). A total of 368 periapical radiographs of endodontic treatment performed by undergraduate students between 2012 and 2014 was assessment. The quality of root canal filling was based on two criteria: length of root canal filling and adequate density of the obturation. Root canal fillings were considered adequate if had no voids and were located at 0-2 mm below the radiographic apex. Statistical analysis was conducted using chi-square tests, with a 5% significance level. In 93.8% of the cases the root canal filling was considered adequate. The density of the obturation was considered inadequate in 3% of the cases. When the length of root canal filling was observed, 1.2% of cases were considered as over-filled and 2.2% were considered under-filled. Non-significant differences were observed among the tooth type (incisive, canines and pre-molars) and the quality of root canal filling. Most of root canal filling performed by undergraduate students at the UFES were considered adequate, regardless of tooth type.

ABSTRACTObjectives: The purpose of this study was to evaluate the radiographic quality of root canal fillings performed by first and second clinical year dental students at the Faculty of Dentistry in Süleyman Demirel University, Turkey. Methods: The technical quality of 833 root canal fillings was evaluated by three examiners according to the density of the filling and the distance between the end of the filling and the radiographic apex. A root canal with acceptable filling length and homogeneous root filling was defined as being good quality endodontic work (GQEW). A treated tooth was defined as having good quality endodontic work tooth (GQEW-T) when all its canals had a GQEW rating. Results: A Chi-square (χ2) test at the 0.05 significance level was used for the statistical analysis of the data. Of a total of 833 root canals, 662 (79.47%) root fillings were classed as GQEW. Two hundred fifty canals (73.4%) (135 teeth) treated by first clinical year dental students were defined as GQEW-T while 412 canals (204 teeth) (73.9%) treated by second clinical year dental students were defined as GQEW-T (P>.05). Most of the GQEW-T were defined in anterior teeth (90.1%), whereas the fewest were in molar teeth (46.6%) for both first and second clinical year dental students (P<.001). Conclusions: The quality of root canal fillings in anterior teeth performed by undergraduate dental students in Isparta, Turkey was satisfactory. However, to improve the success with molar teeth, education about newer techniques and instruments must be incorporated into the preclinical and clinical curriculum. (Eur J Dent 2011;5:324-330)

Objectives: This study aimed to evaluate the technical quality of root canal treatment performed by fifth-year underperforming students, in the extra sessions of the 2018–2019 academic year. Methods: Periapical radiographs of teeth endodontically treated by underperforming undergraduate students at King Abdulaziz University Faculty of Dentistry, were collected. The quality of obturation was evaluated radiographically in relation to the length of obturation to root apex, homogeneity and density of obturation, root canal tapering, and incidence of mishaps (such as perforation, ledge, missed canal, separated instruments). The data were subjected to descriptive analysis. Results: The periapical radiographs of 70 treated teeth showed acceptable length, filling density and root canal taper in 96 (80%),50 (41.7%) and 66 (55%) root canals, respectively. Only four teeth were subjected to mishaps. Conclusion: Under the circumstances of this study, the quality of endodontic treatment performed by underperforming students at the extra session was low. More studies are needed to address the student underperformance source and hence amend the quality of root canal filling.

SUMMARYAim: To evaluate technical quality of root canal treatments performed in extracted anterior single-rooted teeth in an undergraduate dental clinic, and to record the associated iatrogenic errors.Material and Method: 287 root canal treatments performed by 114 preclinical undergraduate students in extracted anterior teeth at the Department of Endodontology were radiographically evaluated, based on the following parameters: access cavity dimensions and direction, root canal instrumentation, and root canal filling quality.Results: The access cavity was found of adequate dimensions in 28.9% and straight in direction in 71.1% of the material. Erroneous position, overextension of the access cavity and non-straight access were noted in 39.7 %, 21.6% and 28.9% of the cases, respectively. The frequency of ledged root canals was 10.1%, while 84.7% of the teeth had no instrumentation related iatrogenic errors. Regarding root canal filling, incomplete density apically and technical inadequacies in the middle and cervical thirds were observed in 76.3% and 82.3% of the cases. The percentage of flawless endodontic treatments was 3.1%.Conclusions: Most of the endodontic treatments evaluated were classified unacceptable. Inadequate root canal filling density in the middle and cervical third and ledge formation were the most common faults.

ABSTRACT Objective to investigate the quality of root canal treatments performed by undergraduate students. Methods 274 root-filled teeth (excluding molars) from the Department of Endodontology of the Federal University of Santa Catarina in a nine-year period were selected and evaluated by two calibrated examiners. The evaluation was based on tooth type, number of root canals, presence or absence curvature, length of filling material considered the radiographic apex as reference (considered adequate shorter than 2mm from radiographic apex), filling material density, filling taper, and overall quality of RCT. Chi-square and Fisher exact tests were performed to analyze associations between variables of interest (p<0.05). Results 197 RCT were classified as acceptable (71.9%). The frequency of adequate RCT was significantly higher in incisor (79.4%) than in premolars (66.4%) or canines (58.1%) (p=0.015). The number of canals did not influence root canal quality in this sample (p>0.05). The factor more frequently identified as unacceptable was filling length (26.6%). All RCT performed in curved teeth and classified as unacceptable were underfilled. Procedural errors, such as perforations or instrumental separation, were not found in this sample. Conclusion The most common criteria identified as unacceptable was the length of the filling material. Incisors had better quality assessment rates than canines and premolars. The high-quality rates found in this sample may be linked to the professor/student rates.

AbstractTechnical quality of endodontic treatment can influence dental prognosis. The aim of the present study was to evaluate radiographically the initial periapical condition and the technical quality of root canal fillings performed by endodontic residents at UEM in 2015 and 2016. After data collection and descriptive statistics, performed by two independent examiners, the Kappa coefficient was used to assess the agreement between them. The chi-square test was used to verify a possible association of sex, tooth and quality of the restoration, with the presence of a periapical lesion. Most referrals for endodontic treatment were molars (50.5%) and female patients (63.2%), with a mean age of 39.3 (± 13.3) years. Most teeth were diagnosed with pulp necrosis (44.1%), and this condition held 74% of the teeth with chronic periapical lesions. Bone rarefaction was seen mainly in molars (20%) and teeth without restorative treatments (43.5%). Chi-square test evidenced that sex (p=0.303), tooth (p=0.349) and quality of restoration (p=0.070) were not associated with the presence of periapical bone rarefaction. After finishing the 233 root canal fillings, the apical limit and condensation were satisfactory in 91% and 100% of cases, respectively. In conclusion, the presence of chronic periapical lesion was not associated with sex, tooth or quality of the restoration. The root canal fillings performed by endodontic residents was satisfactory. Keywords: Endodontics. Root Canal Therapy. Periapical Periodontitis. ResumoA qualidade técnica do tratamento endodôntico pode influenciar no prognóstico dentário. Este estudo teve como objetivo avaliar radiograficamente a condição periapical inicial e a qualidade técnica das obturações dos canais radiculares realizadas pelos residentes em Endodontia da UEM nos anos de 2015 e 2016. Após a coleta de dados e estatística descritiva, realizada por duas examinadoras independentes, empregou-se o coeficiente Kappa para avaliar a concordância entre as mesmas. O teste de qui-quadrado foi utilizado para verificar uma possível associação entre as variáveis sexo, tipo dentário e qualidade da restauração, com a presença de lesão. A maioria dos encaminhamentos para atendimento foram molares (50,5%) e pacientes do sexo feminino (63,2%), com idade média de 39,3 (± 13,3) anos. Uma grande parcela dos dentes foi diagnosticada com necrose pulpar (44,1%), sendo que esta condição abrangeu 74% dos dentes com lesão periapical crônica. A rarefação óssea foi visualizada sobretudo em molares (20%) e dentes sem tratamentos restauradores (43,5%). Por meio do teste de qui-quadrado, houve evidências amostrais de que o sexo (p=0,303), o tipo dentário (p=0,349) e a qualidade da restauração (p=0,070) não estiveram associados à presença da rarefação óssea periapical. Após a finalização dos tratamentos e um total de 233 canais obturados, o limite apical e a condensação da obturação se mostraram satisfatórios em 91% e 100% dos casos, respectivamente. Conclui-se que a presença da lesão periapical crônica não esteve associada ao sexo, tipo dentário ou qualidade da restauração. A obturação dos canais radiculares realizada pelos residentes em Endodontia se mostrou satisfatória. Palavras-chave: Endodontia. Tratamento do Canal Radicular. Periodontite Periapical.

SummaryBackground/Aim: To investigate the incidence of procedural errors with the use of a novel nickel-titanium rotary system (Hyflex CM, Coltene/Whaledent, Altstätten Switzerland), evaluate the technical quality of root canal treatments and assess a questionnaire completed by the participants themselves in an undergraduate dental clinic between 2014 and 2017 (Department of Endodontology, School of Dentistry, Aristotle University of Thessaloniki).Material and Methods: 118 undergraduate students in their first year of clinical practice performed a root canal treatment on a patient’s molar (maxillary/mandibular). None of the participants had previous experience in rotary instrumentation. The periapical radiographs were taken with the use of the paralleling technique for standardization and were collected and evaluated by the investigator. After the root canal treatment was performed the students completed a questionnaire in order to evaluate their training on rotary instrumentation.Results: The overall incidence of instrument separation, apical perforation, root perforation, straightening and ledges was 0.8%, 4.4%, 2.3%, 5.5% and 29% respectively on root canal level. Ledges were detected more often in mandibular mesiobuccal canals. The frequency of root canals with an ‘acceptable’ filling was 68.4%, while overfilled and underfilled canals were found to be 8.6% and 16.2% respectively. The response rate was high (94.9%), 35% of the participants encountered no difficulty in the use of rotary instrumentation and 98.2% would use it again.Conclusions: The incidence of procedural errors was considerably low and the technical quality of the filled root canals was superior to that of similar studies. The responses of the questionnaire demonstrated a positive attitude toward rotary instrumentation.
