Abstract
Background: The aim of this study was to evaluate the radiographic technical quality of root fillings and the incidence of iatrogenic errors in treatments performed by endodontists and dentists.Methods: 1135 radiographic records of endodontic treatments performed by endodontists and dentists were qualified to be further investigated. Radiographs were assessed by two independent endodontists. The length and the density of the obturations and iatrogenic errors were investigated. Chi-square tests were used for statistics.Results: According to iatrogenic errors; the presence of instrument fractures was significantly higher in the endodontists, and likewise, in the mesiobuccal canals of the mandibular teeth (p<0.05). dentists were found more likely to treat the root canal in poor radio-opacity and short filling-overfilling (p<0.05). no significant difference was found between the groups in other iatrogenic errors (p>0.05).Conclusion: The results of this retrospective study show that the canal treatment performed by endodontists were better in terms of the quality of the root canal filling than dentists.
