Objectives-A systematic review of the literature was undertaken to assess the evidence to support a specific time interval between periodontal maintenance (PM) visits.Methods-Relevant articles were identified through searches in MEDLINE, EMBASE and PubMed using specific search terms, until April, 2014, resulting in 1095 abstracts and/or titles with possible relevance. Critical Appraisal Skills Programme (CASP) guidelines were used to evaluate the strength of studies and synthesize findings. If mean recall interval was not reported for study groups, authors were contacted to attempt to retrieve this information.Results-Eight cohort studies met the inclusion criteria. No randomized control trials were found. All included studies assessed the effect of PM recall intervals in terms of compliance with a recommended regimen (3-6 months) as a primary outcome. Shorter PM intervals (3-6 months) favored more teeth retention but also statistically insignificant differences between RC and IC/EC, or converse findings are also found. In the 2 studies reporting mean recall interval in groups, significant tooth loss differences were noted as the interval neared the 12 month limit.Conclusions-Evidence for a specific recall interval (e.g. every 3 months) for all patients following periodontal therapy is weak. Further studies, such as RCTs or large electronic database evaluations would be appropriate. The merits of risk-based recommendations over fixed recall interval regimens should be explored.

Implementation and dissemination of an oral care initiative enhanced the safety and well-being of Veterans at the Salem VA Medical Center by reducing the risk of non-ventilator-associated hospital-acquired pneumonia (NV-HAP). The incidence rate of non-ventilator-associated hospital-acquired pneumonia decreased from 105 cases to 8.3 cases per 1000 patient-days (by 92%) in the initial VA pilot, yielding an estimated cost avoidance of $2.84 million and 13 lives saved in 19 months postimplementation. The team was successful in translating this research into a meaningful quality improvement intervention in 8 VA hospitals (in North Carolina, Texas, and Virginia) that has promoted effective and consistent delivery of oral care across hospital service lines and systems, improved the health of Veterans, and driven down health care costs associated with this largely preventable illness. The steps needed for successful replication and dissemination of this nurse-led, evidence-based practice are summarized in this article.
