Treatment Protocol in Failed Endodontics

Introduction the causes of endodontic failure are many. It is proposed a treatment protocol in failed endodontics. Material and methods in a private clinic in the city of Salamanca, 544 endodontics were performed from March 2015 to February 2018. The proportion of failures and the type of treatment was studied. Results 3.12 % endodontics gave problems, but the dentist had considered correct 2.57 % and only 0.55 % with the possibility of failing. The patients came to the dental clinic after an average of 6.3 months. Medication was done in 100 % of the cases, nonsurgical retreatment in 35.29 %, periapical surgery in 5.88 % and extractions in 17.64 %. Discussion Failed endodontics and areas of periapical radiolucency can occur even in teeth with apparently well-instrumented canals. A periapical radiolucency is not always a failure of endodontics. Conclusions it is proposed Step 1 medication antibiotic + anti-inflammatory. Step 2 nonsurgical retreatment, with * Disposal of material and disinfection (different days, several months). * Over-instrumentation with files can be done to try to periapical lesion react to the healing. * When there is no infection in 3 consecutive months will be filled with gutta-percha and finished. Step 3 periapical surgery. Step 4 extraction.
