title: Efficacy of MTA and CEM Cement with Collagen Membranes for Treatment of Class II Furcation Defects.
abstract: OBJECTIVE
  This study aimed to compare the efficacy of MTA and CEM cement in Class II furcation defects in human mandibular molars.
  
  
  METHODS
  Forty furcation defects were treated in 16 patients with chronic periodontitis. The clinical parameters of probing depth (PD), vertical and horizontal clinical attachment levels (VCAL and HCAL), open vertical and horizontal furcation depths (OVFD and OHFD), and gingival margin level (GML) were measured at baseline and at 3- and 6-month (re-entry surgery) postoperatively. Data were analyzed at a significance level of P<0.05.
  
  
  RESULTS
  Use of MTA and CEM caused significant decreases in PD, VCAL, HCAL, OVFD and OHFD at re-entry, with no statistically significant differences between the two treatment options in soft and hard tissue parameters.
  
  
  CONCLUSIONS
  Both treatment modalities caused significant gains in attachment levels and bone fills, proving efficacy for treatment of Class II furcation involvements.
