NCT02913248

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.

Outcome Measures

Primary Outcomes (1)

  • Changes in α-diversity in saliva samples collected .

    Comparison of α-diversity in saliva samples collected before periodontal treatment and 12 weeks after treatment

    Baseline and 12 weeks

Secondary Outcomes (1)

  • Specis specific changes in saliva samples collected

    Baseline and 12 weeks

Study Arms (1)

Conventional periodontal treatment

EXPERIMENTAL

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.

Procedure: Conventional periodontal treatment

Interventions

Non-surgical periodontal treatment including thorough instruction in self-performed oral hygiene

Conventional periodontal treatment
