BACKGROUND: The treatment of molar @entity6876 remains a considerable challenge in clinical practice. The degree of success in the management of furcation involvement is highly variable and inversely related to initial @entity92 ( @entity92 ) measurements in these lesions. The identification of clinical measurements influential to the treatment outcomes is critical to optimize the results of surgical periodontal therapy. Therefore, the objective of this study was to evaluate the clinical response of mandibular buccal Class II furcation lesions to a combined regenerative treatment modality. METHODS: Sixty @entity1 were divided into two (n = 30) treatment groups. An experimental combined regenerative therapy (ET) was compared to open flap debridement (OFD). The ET was a combination of a composite graft consisting of bioabsorbable @entity692 and @entity803 (3:1), a guided tissue regeneration barrier, and a coronally advanced flap. The clinical variables evaluated were plaque, @entity548 on probing, @entity1464 , @entity92 , vertical attachment level (VAL), horizontal attachment level (HAL), furcation vertical height, furcation horizontal depth, and the amount of tissue under the barrier membrane at uncovering. Reevaluation was performed 12 months after the surgical procedure. RESULTS: Both treatments resulted in improvements in all clinical variables evaluated. Postoperative measurements revealed a reduction in @entity92 of 3.65 +/- 0.6 mm and 0.60 +/- 1.0 mm; VAL gains of 3.05 +/- 0.6 mm and 0.65 +/- 0.6 mm and HAL gains of 3.45 +/- 1.3 mm and 0.55 +/- 0.7 mm in the ET and OFD groups, respectively. In the ET group, significant positive correlations were found between baseline @entity92 and @entity92 reduction at 12 months, and the initial VAL correlated positively with @entity1017 . The horizontal furcation depth and amount of tissue formed under the membrane at uncovering correlated positively with @entity10273 . For the OFD group, the initial @entity92 correlated positively with @entity10273 and correlated negatively with recession. Initial VAL correlated positively with @entity10273 . The initial HAL correlated negatively with recession at 12 months. CONCLUSIONS: ET exhibited significantly better clinical results, with more @entity10273 , and a higher frequency of furcation closure compared to OFD and showed promise as a regenerative treatment technique. The ability to predict a response to treatment based upon pretreatment parameters was not consistent between groups; thus, prediction of treatment outcomes based on pretreatment measurements should be carefully evaluated for each treatment modality.
