Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The maintenance consultations will be scheduled every 3 months for 24 months. The hypothesis is that the effect of the supragingival control (conducted over 24 months) will be similar to the effect of the supra- and subgingival control combined, above the restoration and progression of periodontitis.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Supragingival biofilm control
Group 1 - Supragingival biofilm control
30 days after the end of periodontal treatment, participants assigned to this group, will receive every 3 months (over 24 months):
* Scaling, planning and polishing coronary surface;
* Education and motivation for oral hygiene and daily supragingival biofilm control by the patient.
Supra- and subgingival biofilm control
Group 2 - Supra- and subgingival biofilm control
30 days after the end of periodontal treatment, participants assigned to this group, will receive every 3 months (over 24 months):
* Scaling, planning and polishing of coronary surface;
* Education and motivation for oral hygiene and daily supragingival biofilm control by the patient;
* Subgingival scaling and root planning in sites with persistent bleeding on probing and probing depth unchanged.
