Thirteen healthy Beagles, 3 1/2–5 years of age with moderate to advanced periodontal discase received a thorough scaling and prophylasis followed by four weeks of daily tooth cleaning. After one month, each of the fourposterior quadrants of each dog was subjected to one of the following treatments: 1) subgingival curettage, 2) modified Widman flap surgery with root planing, 3) apically repositioned flap and bone surgery for pocket elimination and 4) scaling and root planing as a control. Toothbrushings was carried out daily. In addition, every 14 days the dogs received a rubber cup and pumice prophylaxis throughout the entire length of the study. At the baseline, 1, 6, 12, 24 and 36 months following treatment, oral hygiene and gingival health were scored and the level of periodontal attachment and pocket depth were measured. The results at one Month suggested an increase in attachment levels which was grater after scaling or subgingival curettage than after flap procedures. Up to 36 months, the established attachment levels were maintained for all treatment groups and no significant difference was found between any of the treatments and the scaled controls. However, in advanced periodontal lesion attachment levels were not maintaned with scaling alone. The present study has shown that the more conservative approaches to the treatment of periodontal disease such as subgingival curettage and Widman flap surgery may be as effective in maintaining clincal attachment levels as elaborate surgical procedures involving osteoectomy.
