Salivary Bacterial Profiles in Relation to Periodontal Treatment

Not Applicable

Completed

• Conditions: Periodontitis

• Registration Number: NCT02913248
• Lead Sponsor: University of Copenhagen

Brief Summary

The purpose of the present investigation is to record and compare bacterial compositions in subgingival plaque samples and saliva samples in subjects receiving periodontal treatment. The hypothesis is that the composition of the salivary microbiota might reflect local bacterial alterations in relation to periodontal treatment.

Detailed Description

In this study we plan to enroll 35 subjects with manifest periodontitis, which will be treated according to national and international guidelines. Clinical registration and collection of subgingival plaque samples and saliva samples will be performed at baseline and 2, 6 and 12 weeks after treatment.
