About

This study compared the gain of periodontal attachment after concomitant one-stage removal of bacterial biofilms and subgingival calculus with a two-stage procedure removing subgingival calculus 6 weeks after the initial removal of soft subgingival bacterial biofilms.

Full description

The concomitant removal of subgingival calculus and soft bacterial biofilms in a one-stage procedure might impair periodontal healing in deep infrabony pockets due to the mechanical disruption of demineralized bone sections at the bottom of periodontal lesions. This randomized controlled clinical trial therefore aims at comparing the resulting attachment gain 6 months after one-stage antiinfective periodontal therapy comprising the concomitant subgingival removal of soft bacterial biofilms and calculus with a two-stage approach removing subgingival calculus only 6 weeks after the initial removal of soft subgingival bacterial biofilms.

44 participants in 2 patient groups

Two-Stage Subgingival Debridement

Experimental group

Description:

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

Treatment:

Procedure: Subgingival Debridement

One-Stage Subgingival Debridement

Active Comparator group

Description:

Soft subgingival bacterial biofilms, as well as subgingival calculus are concomitantly removed from periodontal lesions by mechanical scaling and root planing

Treatment:

Procedure: Subgingival Debridement
