title: Influence of different post-interventional maintenance concepts on periodontal outcomes: an evaluation of three systematic reviews.
abstract: BACKGROUND
  To selectively review the existing literature on post-interventional maintenance protocols in patients with periodontal disease receiving either non-surgical or surgical periodontal treatment.
  
  
  METHODS
  Three systematic reviews with different periodontal interventions, i.e. scaling and root planing (SRP), SRP with adjunctive antibiotics or regenerative periodontal surgery were evaluated focusing on their post-interventional maintenance care. Due to the early publication of one review an additional literature search update was undertaken. The search was executed for studies published from January 2001 till March 2015 through an electronic database to ensure the inclusion of resent studies on SRP. Two reviewers guided the study selection and assessed the validity of the three reviews found.
  
  
  RESULTS
  Within the group of scaling and root planing alone there have been nine studies with more than three appointments for maintenance care and five studies with more than two appointments in the first 2 months after the intervention. Chlorhexidine was the most frequently used antiseptic agent used for 2 weeks after non-surgical intervention. Scaling and root planing with adjunctive antibiotics showed a similar number of visits with professional biofilm debridement, whereas regenerative studies displayed more studies with more than three visits in the intervention group. In addition, the use of antiseptics was longer and lasted 4 to 8 weeks after the regenerative intervention. The latter studies also showed more stringent maintenance protocols.
  
  
  CONCLUSIONS
  With increased interventional effort there was a greater tendency to increase frequency and duration of the maintenance care program and antiseptic agents.
