Abstract
The aim of the present clinical trial was to evaluate the effect of different modes of periodontal therapy on patients with moderately advanced periodontal disease and to express the findings in terms of probing pocket depth and attachment level alterations at periodontal sites with different initial probing depths.The material consisted of 16 patients, 35–65 years of age. Following a Baseline examination including assessments of oral hygiene status, gingival conditions, probing pocket depths and probing attachment levels, the patients were subjected to periodontal treatment. A “split‐mouth” design approach of therapy was used and the jaw quadrants were randomly selected for the following different treatment procedures: (1) scaling and root planing, (2) scaling and root planing in con junction with a gingivectomy procedure, (3) scaling and root planing m conjunction with an apically repositioned flap procedure without bone recontouring. (4) scaling and root planing in conjunction with an apically repositioned flap procedure including bone recontouring, (5) scaling and root planing in conjunction with a modified Widman flap procedure without bone recontouring and (6) scaling and root planing in conjunction with a modified Widman flap procedure including bone recontouring. The patients were following active treatment enrolled in a supervised maintenance care program including “professional tooth cleaning” once every 2 weeks during a 6‐month period of healing, after which a final examination was performed.The investigation demonstrated that active therapy including meticulous subgingival debridement resulted in a low frequency of gingival sites which bled on probing, a high frequency of sites with shallow pockets (6 mm. Between the Baseline examination and the 6‐month re‐examination, the probing attachment level for initially shallow‐pockets remained basically unaltered, but with a tendency of a minor apical shift. This occurred in all 6 treatment groups. For sites with initial probing depths of 4–6 mm and >6 mm, there was in all groups some gain of probing attachment. This gain was most pronounced in the initially deeper (>6 mm) pockets.With the use of regression analysis, the “critical probing depth” (CPD) value (i.e. the initial probing depth value below which loss of attachment occurred as a result of treatment and above which gain of probing attachment level resulted) was calculated far each of the 6 methods of treatment used‐ A comparison of the CPD‐values between the 6 treatment groups did not reveal any major differences.
