This review compared the survival of mandibular overdentures supported by 1- or 2- implants. Only two small RCTs were identified that suggest no difference between 1- or 2- implants. However only a small number of patients were included in these trials so the evidence is weak and more high quality trials are required.

This large Swedish questionnaire survey conducted on a random sample of patients achieved a high response rate (83%) . Those who had received dental implant supported restorative treatment reported very high levels of satisfaction (94%). However, 31% had experienced implant related complications although only 6% reported that these complications occurred frequently.

This review compared root fracture rates of metal and fibre root canal posts and found not difference. While 14 studies were included only 7 were randomised trials and all were of low quality so higher quality studies are needed.

This review of caries excavation strategies identified 28 studies including 19 RCTs. None were considered to be at low risk of bias . The results suggest that not attempting to remove all softened or stainable dentine could reduce the risk of complications

This review looks at dental implants placed in the maxillary tuberosity only 5 low quality studies involving 113 patients were found in total. While good survival rates were found these should be interpreted with caution.

This small study found good short term success rates for a new MTA derived pulp capping material in permanent teeth. Larger well-conducted longer-term studies are necessary to establish its clinical utility.

This new review identified 22 studies but no randomised trials and found a higher dental implant failure rate in periodontally compromised patients than health ones. However concerns over study quality means the findings should be interpreted with caution.
