This review of whether supportive care is effective in preventing recurrence or progression of peri-implantitis included 15 studies. However none of the included studies was specifically designed to test supportive care regimens so there is a need for new well conducted and reported randomised trials of appropraite size and duration to provide better quality evidence.

This review comparing of air polishing devices with conventional periodontal therapy (hand instrumentation and/or ultrasonic debridement), in patients undergoing periodontal maintenance therapy included 14 RCTs. The findings suggest that they have comparable clinical efficay although the evidence is of low certainty.

This review of adjunctive therapies during supportive periodontal care (SPC) in patients with residual/relapsing pockets included 12 studies that currently provide insufficient/poor evidence to determine the efficacy of adjunctive strategies to improve SPC.

This review of air polishing devices (APDs) in comparison with hand instruments and/or power-driven instruments in supportive periodontal treatment and implant maintenance included 6 RCTs. 4 of the 6 included studies were considered to be at high risk of bias so the findings should be interpreted cautiously.

This review evaluating risk factors / predictors of tooth loss in patients with periodontitis having periodontal therapy and long-term periodontal maintenance (PM) included 33 studies only 3 of which were prospective. There findings suggest that patients having long-term PM suffer the loss of 1 tooth per patient every 10 years.

This review of the impact of supportive periodontal treatment (SPT) following implant placement on peri-implant disease and survival rates included 9 studies. While the findings suggests that SPT can improve peri‐implant health the quality of the available evidence is limited so high quality well conducted prospective studies are needed.

This review of predictors of tooth loss in patients with periodontitis undergoing treatment and receiving supportive care included 20 studies. Findings suggest older, non‐compliant patients, smokers, diabetics, those with IL‐1‐polymorphism, and teeth with bone loss, high probing pocket depths, mobility, as well as molars, especially with furcation involvement, are at higher risk of tooth loss.

This Cochrane review of the effects of supportive periodontal therapy (SPT) in the maintenance of the dentition of adults treated for periodontitis included 4 RCTs providing is insufficient evidence to determine the superiority of different protocols or adjunctive strategies to improve tooth maintenance during SPT.

In patients with moderate to advanced periodontitis this longitudinal study demonstrated that long-term tooth retention is possible for compliant patients using a non-regenerative treatment concept.

This review of the impact of furcation involvement on tooth loss in periodontal disease found 21 pro- and retrospective studies. The data suggests that the risk of tooth loss may be doubled where there is furcation involvement.
