title: Bioactive glass granules for regeneration of human periodontal defects.
abstract: OBJECTIVE
  A comparative study which evaluated the effectiveness of bioactive glass granules of uniform size (300-335 microns) for the regenerative treatment of interproximal intrabony periodontal defects was conducted.
  
  
  METHODS
  Twelve pairs of advanced periodontal lesions in 12 patients (6 males and 6 females) were treated in a split-mouth design with open flap débridement in the control sites and open flap débridement with bioactive glass particles placed in the test sites.
  
  
  RESULTS
  At 6 months post-treatment, both treatment modalities demonstrated a gain in clinical attachment level (CAL), with the test sites having a significantly (p < .01) greater gain in CAL than the control sites. Reentry procedures were performed to assess the amount of hard tissue fill. The test sites demonstrated significantly (p < .001) more gain in hard tissue fill than the controls.
