Root fillings with Endoflas in primary teeth: a retrospective study.

The aim of this retrospective study is to report the success rate of root canal treatments (RCT) using Endoflas as a filling material in primary teeth. Fifty-five (55 teeth, 27 maxillary incisors and 28 molars) of 47 children fulfilled the criteria to be included in the study. The immediate post-operative radiograph was evaluated and the root filling was rated overfilled, flush or underfilled. Thirty-one (31) teeth were overfilled; of these 9 (29%) were normal pre-operatively and the remaining 22 (71%) presented with bone pathology. Twenty-four (24) teeth were flush or underfilled; of these, 50% had preoperative bone pathology. The children were examined clinically and radiographically at follow-up visits ranging from 6 to 52 months. Approximately 70% of the cases were successful at the last followup examination. The remaining 30% presented with pathology (Po); however, only one tooth had to be extracted (Pi). Overfilling led to a success rate of 58%, while in the combined flush and underfilled the success rate was 83%.
