NCT01522131

Brief Summary

Purpose: The proposed study will evaluate and compare the clinical response of using bioresorbable collagen membrane alone or defect debridement with erbium Laser irradiation in conjunction with bioresorbable collagen membrane in the treatment of Class II furcation defects in maxillary and mandibular teeth. The study will examine whether there is a superior regeneration potential when the laser energy is combined with membrane defect isolation. Procedure: The study will use 2 groups, a control group and a test group with 16 patients in each group, with severe chronic periodontitis having clinical or radiographic evidence of Class II furcation defects in the buccal or lingual of the mandibular molars or Class II furcation defects on the buccal of maxillary molars. 16 patients will serve as the control group and open flap debridement with bioresorbable collagen membrane will be the mode of treatment. Group 2: 16 patients will serve as the test group and will undergo open flap debridement in conjunction with Er, Cr: YSGG laser irradiation and a bioresorbable collagen membrane will be used.

Outcome Measures

Primary Outcomes (1)

  • Change in Clinical Attachment( Gain or Loss) Measured by Horizontal Clinical Attachment Loss(in mm) From Baseline to 6 Months.

    Patients with periodontitis lose bone and clinical attachment over a period of time. In both control and test a Nabers probe( curved probe) marked in mm was used to quantify this loss or gain of clinical attachment in a horizontal direction from the cemento-enamel junction to the the most apical extent of the bone at the furcation entrance at baseline and after 6months after the procedure. These measurements were done intrasurgery and before opening of the flaps,again both at initial visit and 6 months after the procedure was done. This measurement will be measured in mm in postive numbers and then will be compared to measurements ( in mm) at intial and baseline. If there is a loss in attachment it will be denoted by negative number. If theres a gain in attachment it will be denoted by a positive number after the comparison.

    At Baseline and 6 months

Secondary Outcomes (1)

  • Clinical Evidence of Regeneration of Class 2 Furcation Defects Based on Changes in Vertical Pocket Depth Measurement(in mm)

    At Baseline and 6 months

Study Arms (2)

Bioresorbable membrane will be used as the control

OTHER

Bioresorbable membrane alone (control)

Procedure: bioresorbable membrane alonewill be used for regeneration of the periodontium(control)

laser with bioresorabable membrane (test)

EXPERIMENTAL

Interventions

bioresorbable membrane with laser will be used for regeneration of the periodontium(test)

Bioresorbable membrane will be used as the controllaser with bioresorabable membrane (test)
