title: Early postoperative healing following buccal single flap approach to access intraosseous periodontal defects.
abstract: OBJECTIVE
  This study aims to evaluate the early postoperative healing of papillary incision wounds and its association with (1) patient/site-related factors and technical (surgical) aspects as well as with (2) 6-month clinical outcomes following buccal single flap approach (SFA) in the treatment of intraosseous periodontal defects.
  
  
  METHODS
  Forty-three intraosseous defects in 35 patients were accessed with a buccal SFA alone or in combination with a reconstructive technology (graft, enamel matrix derivative (EMD), graft + EMD, or graft + membrane). Postoperative healing was evaluated at 2 weeks using the Early Wound-Healing Index (EHI).
  
  
  RESULTS
  EHI ranged from score 1 (i.e., complete flap closure and optimal healing) to score 4 (i.e., loss of primary closure and partial tissue necrosis). SFA resulted in a complete wound closure at 2 weeks in the great majority of sites. A significantly more frequent presence of interdental contact point and interdental soft tissue crater, and narrower base of the interdental papilla were observed at sites with either EHI > 1 or EHI = 4 compared to sites with EHI = 1. No association between EHI and the 6-month clinical outcomes was observed.
  
  
  CONCLUSIONS
  At 2 weeks, buccal SFA may result in highly predictable complete flap closure.
  
  
  CONCLUSIONS
  Site-specific characteristics may influence the early postoperative healing of the papillary incision following SFA procedure. Two-week soft tissue healing, however, was not associated with the 6-month clinical outcomes.
