Radiographic quality of root canal fillings performed by undergraduate students of the Dental School of Athens
Summary:
Introduction: Between 2004 and 2006 a study on the radiographic quality of undergraduate students was conducted. As a result several educational measures were taken to improve the preclinical education in Endodontics.

Aim To evaluate the radiographic quality of root fillings and the incidence of iatrogenic errors in root canal treatments provided by undergraduate students and investigate whether the changes introduced had a positive effect on their performance.


Methodology Periapical radiographs of 570 teeth and their 976 root filled canals, performed by undergraduate students of the 4th and 5th year during the academic years 2012-15, were randomly selected. The sample was digitalized and assessed, by two independent investigators, as acceptable or non-acceptable according to two variables: the length and density of the root filling. Iatrogenic errors including ledges, perforations (root and apical foramen) and fractured instruments were also recorded. Root canal was the unit of assessment. Chi-square tests and multivariable random effects logistic regression models were used for statistical analysis.
Results Acceptable root fillings were found in 62.7% of canals, with similar percentages between the 4th and the 5th year students. Iatrogenic errors were noted in 19.4% of all cases, with the presence of ledges significantly reduced in the root canal treatments of the 5th year students (P < 0.05). Molars exhibited the majority of problems concerning quality and iatrogenic errors.
Conclusions The quality of the root fillings was improved (62.7% vs 54.8%) and the incidence of iatrogenic errors was decreased (19.4% vs 31,6%) in comparison with the previous research in Dental School of Athens. Significant attention must be given to the root canal treatment on molars through additional improvements on the educational system.
