This review included 12 small in vitro and in vivo studies of Cone Beam Computed Tomography (CBCT) for the diagnosis of a root fracture. While the data suggest the ability to detect root fractures in non-endodontically treated teeth, the findings should be interpreted with caution.

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.

The review of sleep bruxism was only able to identify 12 small low quality RCTs covering a range of treatments. Most evidence was available for oral appliances but there is no sufficient evidence to state that the occlusal splint is effective for treating sleep bruxism.

This review of dental implants failure in males and females included 91 studies. The majority were retrospective with only 4 RCTs. While suggesting higher failure rates in males than females, the study quality and confounders mean that the results should be treated with caution.

Only 12 small studies of limited quality were available for this review on CAD-CAM-fabricated implant-supported restorations. While they showed promising short-term outcomes, they should be interpreted with caution.

This review of antibiotic prophylaxis during dental implant placement considered both systematic reviews and RCTs. Evidence from the 10 included RCTs suggests a small reduction (2%) in the risk of implant loss. These results are similar to a recent Cochrane review.
