Measure
Two-Stage Subgingival Debridement
Initially soft subgingival bacterial biofilms are removed from periodontal lesions by an airpolishing device and erythritol cleaning powder. 6 weeks later subgingival calculus is mechanically removed in a second step by mechanical scaling and root planing Subgingival Debridement: Removal of subgingival bacterial biofilms and subgingival calculus from periodontal lesions
One-Stage Subgingival Debridement
Soft subgingival bacterial biofilms, as well as subgingival calculus are concomitantly removed from periodontal lesions by mechanical scaling and root planing Subgingival Debridement: Removal of subgingival bacterial biofilms and subgingival calculus from periodontal lesions

SECONDARY outcome

Timeframe: 168 days (24 weeks)

Population: In deviation from the original study protocol, the GI values were not recorded, as bleeding on probing is the relevant measure for assessing the extent of gingival inflammation according to the current classification adopted by the EFP/AAP.

Measuring the mean difference in Gingival Index (GI) scores between baseline and end of the study

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 168 days (24 weeks)

Measuring the difference in the extent of supragingival plaque coverage according to the criteria set by Silness and Loe between baseline and end of study
