Multicenter clinical trials have established that the adjunctive use of the subgingival controlled release of chlorhexidine, in the form of the PerioChip, significantly reduces pocket probing depth, improves probing attachment levels, and reduces bleeding on probing compared to scaling and root planing alone, for periods up to 9 months. The purpose of the present study was to report on the adjunctive use of the PerioChip for the long-term management of adult periodontitis for 2 years. A total of 836 patients with adult periodontitis from private dental offices were recruited into the trial. This interim report is on the first 72 patients to have completed the 2-year study. Treatments included initial definitive therapy followed by PerioChip placement in pocket sites with a pocket probing depth of > or = 5 mm after 1 month. Subsequently, the patients received routine periodontal maintenance therapy together with the placement of a PerioChip in pockets with pocket probing depths > or = 5 mm every 3 months. Results indicated that there was a continuous decrease in pocket probing depth over the 2 years (1.26 +/- 0.77 mm). This decrease in pocket probing depth was marked over the first 9 to 12 months, and then appeared to be less marked over the next 12 months. At 2 years, 60% of the patients had at least 2 pockets showing a reduction of 2 mm or more, and only 10% of the patients showed no change or increased pocket probing depth. The results indicate that adjunctive PerioChip use is a clinically effective treatment option for dental professionals and their patients for the long-term management of adult periodontitis.
