Reciprocation vs Rotational Single-file Systems in Postoperative Pain

Influence of Reciprocating and Rotational Single-file Systems on the Postoperative Pain: A Randomized Clinical Trial.

In this study, the researchers will investigate the effect of single-file reciprocating versus single-file rotational file systems on the postoperative pain in adult patients who have necrotic pulp and apical periodontitis. The participants will be assigned by chance to separate groups that compare 2 different treatments, reciprocating single-file system (Reciproc Blue) and rotational single-file system (OneShape). As a reference, Mtwo multi-file (full-sequence) will be used.

The infected root canal treatments will be performed using one-visit approach with either a reciprocating single-file system or a continuous rotational single-file system. (Reciproc Blue reciprocating single-file system vs OneShape rotational single-file system). The root canals will be completed in single-visit. The patients will record their postoperative pain during the follow-up period using a VAS scale.

Inclusion Criteria:

• Participants who have in their mandibular or maxillary molar teeth necrotic pulp and apical periodontitis.

Exclusion Criteria:

• Pregnancy, drug hypersensitivity, cardiac problems, previously performed endodontics treatment.
