This review aimed to assess the effect of bioactive glass on bone and periodontal regeneration and included 20 RCTs. The included studies were small, involved numerous comparisions with only two being at low risk of bias. The findings showed a statistically signiciant benefit for probing depth with bioglass but this may not be clinically significant and the limited quality of thei included studies mean the findings should be interpreted cautiously.

This review of the effectiveness of locally delivered adjunctive antibiotic treatment during periodontal surgery on clinical outcomes included 9 RCTs. While the findings suggested that adjunctive locally delivered antibiotics could improve some clinical sutcomes they evidence was limited and of very low certainty.

Mark-Steven Howe looks in detail at a recent network meta-analysis (NMA) of periodontal outcomes following third molar surgery. However the limited number of studies available for the NMA mean the reviews findings need to be interpreted with caution.

Eight small studies were identified for this review of the use of regenerative techniques as an adjunct to periapical surgery. The findings suggest that they improve outcomes after 1 year, but they should be interpreted with caution.
