Dry socket – oral contraceptives may increase incidence
This review included 16 low-moderate quality studies, which overall suggest that the use of oral contraceptives leads to a higher incidence of dry socket. Risk ratio = 1.80 (95% CI; 1.33–2.43).

This review included 13 small studies of limited quality. While the available evidence suggests there may be no difference, further long-term high quality studies are required to confirm if this is the case.

8 studies were included in this review comparing amalgam with composite in posterior restorations. There was a statistically significant benefit in favour of amalgam for both restoration failure and secondary caries.

This 3-centre randomised trial, involving 138 patients, found no clinically significant difference in treatment efficiency between treatment with a self-ligating bracket system and a conventional ligation system.

This review included 11 small low quality studies that suggest clinical benefits at 6 months. Further high quality longer term studies are needed to assess the clinical relevance.

This Cochrane review only identified 4 small short-term trials providing limited evidence for the effectiveness of surgical approaches to accelerate orthodontic treatment. Further research with longer follow up is needed to confirm any possible benefit.

This review of periodontal surgery for multiple gingival recessions includes 9 small RCTs with relatively short follow up periods and suggests that the percentage root coverage can be improved although complete root coverage was more variable.
