Effects of full-mouth scaling and root planing in conjunction with systemically administered azithromycin.
BACKGROUND
One-stage full-mouth disinfection (FMD), in which full-mouth scaling and root planing (SRP) is performed with adjunctive use of chlorhexidine, was introduced in 1995. There have been several reports on the effectiveness of this treatment protocol. However, FMD was reported to induce pyrexia frequently. We examined the effects of full-mouth SRP in conjunction with azithromycin administered orally before SRP to control the number of bacteria. The purpose of this study was to compare the effects of full-mouth SRP using azithromycin with conventional SRP.


METHODS
Thirty-four subjects (17 in the test group and 17 in the control group) with severe chronic periodontitis were selected. The subjects of the test group had azithromycin 3 days before full-mouth SRP. Clinical parameters (probing depth [PD], gingival index [GI], bleeding on probing [BOP], and gingival crevicular fluid [GCF]), total number of bacteria, and number of black pigment-producing rods (BPRs) were evaluated at baseline and 5, 13, and 25 weeks after baseline.


RESULTS
All clinical parameters improved in the test group more than in the control group. In the bacteriologic examination, the total number of bacteria did not change during the examination. In the test group, BPRs were not detected until 13 weeks. However, BPRs were detected in the control group by 13 weeks.


CONCLUSIONS
It was shown that full-mouth SRP using systemically administered azithromycin was a clinically and bacteriologically useful basic periodontal treatment for severe chronic periodontitis.
