Effect of Laser Use on Guided Tissue Regeneration in Treatment of Molar Teeth With Class 2 Furcation Affected by Periodontitis

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.
