T he purpose of this study was to compare, longitudinally, the effectiveness of scaling and root planing, osseous surgery, and the modified Widman procedures. The study was carried out in a private practice setting. Sixteen adult patients with moderate to advanced adult Periodontitis were treated with initial scaling and oral hygiene procedures. Posthygiene data were used for comparison of changes in probing depth, clinical attachment levels and gingival recession. The initial examination data were used to compare changes in plaque and gingival indices. Frequency distributions were used to compare changes that occurred at individual sites. At one year, plaque and gingival indices were significantly reduced when compared with the initial examination. At one year, shallow pockets (1‐3 mm) were reduced when compared to posthygiene. Four‐ to six‐millimeter pockets were significantly reduced by the three procedures. Osseous surgery and modified Widman had significantly greater pocket reduction when compared with scaling. For pockets >7 mm, osseous surgery and the modified Widman had significantly greater reduction when compared with scaling. For pockets 1–3 mm at one year osseous surgery had significantly greater clinical attachment loss when compared with scaling. For 4–6 mm pockets at one year, the three procedures had slight gains in clinical attachment levels. The results were similar for pockets with >7 mm. Interproximal soft tissue craters were measured for six postoperative weeks. Initially, the modified Widman had a higher percentage of soft tissue craters when compared with osseous surgery. At six weeks, however, there were no significant differences when the surgical procedures were compared. Recession was measured at each examination. Recession for 1– 3 mm pockets at one year was greater for osseous surgery when compared with scaling and the modified Widman. Recession for 4–6 mm and >7 pockets was greater for the surgical procedures than scaling. The results from this study indicate that with three‐month maintenance recalls, both the modified Widman and osseous surgery are effective for pocket reduction, and each will produce a slight gain of clinical attachment over one year. Scaling was effective at maintaining attachment levels but was not as effective in reducing pocket depth.
