4 RCTs involving 96 patients were included in this review of osseous resective surgery (ORS) in the treatment of residual periodontal defects.
The findings suggest some benefit from ORS but they should be interpreted cautiously because of the limited number of small studies.
This review of the effect of cortical perforations in bone regeneration considering the surgical technique included 16 small studies. All but one of teh studies was conducted in an animal model providing very little clinically relevant data.

38 RCTs were included in this Cochrane review of the effects of autologous platelet concentrates (APC) used as an adjunct to periodontal surgery. Very low quality evidence was found for two approaches involving open flap debridement.

This review of periodontal regeneration therapies included 52 trials. While the results suggest some statistically significant improvements they may not be clinically important. There is also limited data for outcomes longer than 12 months.

This review of surgical approaches for the management of labially impacted canines only identified 3 small studies at high risk of bias. These provide insufficient evidence to determine the best approach.

Eight small trials were identified for this review of lasers as an adjunct to surgical periodontal treatment. The limited number of studies and variation in the types of lasers used means there is insufficient evidence to support their effectiveness.
