title: Six Month Clinical Evaluation of Interdental Papilla Reconstruction with Injectable Hyaluronic Acid Gel Using an Image Analysis System.
abstract: OBJECTIVE
  Obtaining predictable and aesthetically pleasing interdental papilla is challenging in dental reconstruction. Hyaluronic acid gel has been successfully used to reduce facial creases and similar abnormalities. The purpose of this study was to clinically assess the efficiency of interdental papilla reconstruction with injectable hyaluronic acid gel.
  
  
  METHODS
  Ten patients with 43 treated sites in the maxillary anterior region were studied. Photographic standardization devices were designed for image analysis before treatment. This treatment was repeated up to five times during 3-week intervals. Patients were followed 6 months after initial gel application.
  
  
  RESULTS
  Twenty-nine sites had complete papilla reconstruction and 14 sites improved from 39 to 96% of interdental papilla reconstruction rate. Complete interdental papilla reconstruction was performed when black triangle at initial examination had area of ≤0.25 mm(2) , height of ≤1mm, or width of ≤0.5mm.
  
  
  CONCLUSIONS
  Injectable hyaluronic acid gel may be a promising treatment for enhancing papillary esthetics.
  
  
  CONCLUSIONS
  Interdental papilla reconstruction with injectable hyaluronic acid gel can be suggested as a minimally invasive treatment option for interdental papilla deficiencies in small areas. However, long-term results of this treatment beyond 6 months are not yet known. (J Esthet Restor Dent 28:221-230, 2016).
