About

No clinical evidence has been yet published regarding the comparison of postoperative pain after removal of the root canal fillings with or without solvent. The aim of this study was to evaluate the effect of combined usage of ProTaper retreatment instruments and a gutta-percha solvent, on the postoperative pain intensity after retreatment.

Full description

Scientific literature contains a few studies regarding the amount of apically extruded debris caused by solvent or solvent free use of rotary instruments. It was reported that the use of ProTaper retreatment instruments in combination with gutta-percha solvent reduced the amount of apically extruded debris compared to their solvent free use. Nevertheless,no clinical evidence has been yet published regarding the comparison of postoperative pain after removal of the root canal fillings with or without solvent. The aim of this study was to evaluate the effect of combined usage of ProTaper retreatment instruments and gutta-percha solvent, on the postoperative pain intensity after retreatment. The adult patients (18-59 ages) who referred to Department of Endodontics with a diagnose of failed root canal treatment were examined radiographically and clinically. Endodontically treated, clinically asymptomatic, single-rooted teeth with one canal exhibiting chronic periapical infection were included. A hundred cases who matched the determined criteria were selected and randomly allocated to two groups:

Non-solvent Group (n=50):

ProTaper retreatment instruments were used in combination with with X-Smart electric motor for the removal of root canal fillings.

Solvent Group (n=50):

ProTaper retreatment instruments were used with the abovementioned technique but in combination with a gutta-percha solvent

Enrollment: 90 patients
