Aim: The study was intended to evaluate the efficacy of piezotome versus periotome extractions of non-re- storable endodontically treated teeth in relation to prevention of marginal bone loss, operating time of the procedure, and postoperative sequalae. Methods: Forty-two patients with age range of 30–55 years requiring extraction of maxillary single rooted teeth that failed endodontically were randomly divided into two equal groups, a piezotome group and a periotome group. Clinical assessment was performed through measuring the marginal bone loss, time taken for extraction, postoperative pain and any complications related to the extraction procedure. The data was recorded then analyzed using IBM SPSS software package version 22.0.
Results: The difference between the times required for extraction in both groups was not statistically significant, although slightly longer time was recorded in the piezotome group. The piezotome group showed a statistically significant lower value regarding the marginal bone loss when compared to the periotome group. On the other hand, concerning the severity of postoperative pain, both groups did not show a statistically significant differ- ence.
Conclusions: The results of the present study support that the piezotome was a more efficient choice for pre- servation of marginal bone in endodontically failed teeth indicated for extractions compared to the periotome.
