Following parameters were assessed , Plaque Index ( PI ) , Gingival Bleeding Point Index ( GBI ) , Relative gingival margin level ( RGML ) , Relative attachment level ( RAL ) and Probing pocket depth ( PPD ) Results : In the test group , mean percent defect coverage was 72.43 13.55 % and the predictability was 41.17 % for root coverage i.e 14 of 34 defects , while in the control group , mean percent defect coverage was 82.06 10.99 % and the predictability was 50 % for root coverage i.e 15 of 30 defects .
