Salivary Bacterial Profiles in Relation to Periodontal Treatment

February 2, 2017 updated by: Daniel Belstrøm, DDS, PhD, University of Copenhagen

Short and Long Term Alterations of Subgingival and Salivary Microbiota in Relation to Periodontal Treatment

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.

Conditions

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Conventional periodontal treatment
35 subjects diagnosed with manifest periodontitis, which will all receive standardized treatment according to protocol. In brief, this treatment includes professional tooth cleaning and thorough instruction in self-performed oral hygiene procedures. Clinical registrations and collection of microbiological samples (subgingival and saliva) will performed at baseline and 2, 6 and 12 weeks after treatment.
Non-surgical periodontal treatment including thorough instruction in self-performed oral hygiene
