Eligibility

Age
18 Years to No maximum

Inclusion criteria

Inclusion criteria: Individual adultos of all age (at least 18 years); both man and women; clinical diagnosis of biofilm-induced gingivitis in an intact or reduced periodontium, receiving care in Primary Health Care in the municipality of Capão do Leão, Rio Grande do Sul, Brazil; volunteer patients treated by dentists participating in the study; patients who voluntarily agree to participate and sign the Informed Consent Form; dentists who are members of Family Health Strategy Teams or teams linked to the Primary Health Care Units included in the study, who voluntarily agree to participate and sign the Informed Consent Form

Exclusion criteria

Exclusion criteria: Patients receiving home dental care; patients who underwent periodontal treatment in the previous six months; patients who used antibiotics in the previous three months; patients with a diagnosis of periodontitis; dentists absent from work due to leave or other reasons during the implementation period; dentists who do not participate in the planned data collection stages

Design outcomes

Primary

MeasureTime frame
Evaluate the reduction in bleeding on probing. This outcome will be assessed by the method of full periodontal examination, performed at the initial treatment consultation and at four and six weeks after completion of periodontal treatment. This examination will assess periodontal clinical parameters at six sites of all natural teeth present in the patient’s mouth, except third molars. The following sites will be considered: mesiobuccal, buccal, distobuccal, mesiolingual or mesiopalatal, lingual or palatal, and distolingual or distopalatal. Bleeding on probing will be assessed after insertion of the periodontal probe during the probing depth procedure. In cases of bleeding, a score of 1 will be assigned, and in the absence of bleeding, a score of 0 will be assigned. The results will be recorded by an assistant on a periodontal chart. The percentage of sites with bleeding on probing in relation to the total number of sites evaluated will be observed, and the reduction in this percentage between the initial assessment and the reassessments performed at four and six weeks after periodontal treatment will be evaluated. The number of individuals with a healthy periodontium will also be calculated

Secondary

MeasureTime frame
Evaluate the reduction in the visible plaque index. This outcome will be assessed by the method of full periodontal examination, performed at the initial treatment consultation and at four and six weeks after completion of periodontal treatment. This examination will assess periodontal clinical parameters at six sites of all natural teeth present in the patient’s mouth, except third molars. The following sites will be considered: mesiobuccal, buccal, distobuccal, mesiolingual or mesiopalatal, lingual or palatal, and distolingual or distopalatal. The visible plaque index will be recorded based on the visible presence of bacterial plaque, with a score of 1, or visible absence of bacterial plaque, with a score of 0, without the use of a periodontal probe, after drying the tooth surfaces. The sites presenting bacterial plaque will be counted, and their relative percentage in relation to the total number of sites evaluated will be calculated, with the reduction in this percentage being evaluated between the initial assessment and the reassessments performed at four and six weeks after periodontal treatment; evaluate changes in oral health-related quality of life. This outcome will be assessed through the application of the Brazilian validated version of the Oral Health Impact Profile-14, at the initial treatment consultation and at four and six weeks after completion of periodontal treatment. The total Oral Health Impact Profile-14 score will be observed, ranging from 0 to 56 points, with higher scores indicating a greater negative impact on oral health-related quality of life; evaluate the number of procedures performed in the Primary Health Care Units. This outcome will be assessed through the analysis of dental records and health care indicators from each Primary Health Care Unit. The total number of consultations performed in Primary Health Care by the dentists of the team, the type of dental consultation, including first scheduled dental consultation, dental follow-
