KUNERT, Gustavo Golgo et al. Endodontic retreatment: Analysis of three specialists' retreatment rates. Stomatos [online]. 2015, vol.21, n.41, pp. 35-43. ISSN 1519-4442.

Endodontic retreatment is a clinical intervention intended to correct errors that have occurred in a treatment performed previously. There are several causes of failures. The anatomical variations between root canals and the difficulties of achieving microbial disinfection are reported as two of the main causes. However, in the dental offices of both general practitioners and specialists, it is very common that the causes of indications for endodontic retreatment are technical failures due to poorly executed treatment. In view of this, the objective of this study is to analyze the records of three specialists in Endodontics and analyze the causes for referral of their endodontic retreatment patients. Examination of 24,553 treatments conducted over varying periods revealed that cases of retreatment accounted for a considerable proportion of the routine work performed by these specialists, at an average of 23% of cases. The majority of retreatment indications were due to technical failure of the initial treatment, in combination with microbial factors caused by contamination of coronal restorations and poorly executed endodontic preparation and filling.
