Impact Evaluation of Personalized Oral Hygiene Education on Periodontal Patients Stage I/II/III

Study Overview
=================
Brief Summary
-----------------
Evaluation of personalized oral hygiene education on plaque accumulation and gingival inflammation in periodontal patients stage I/II/III. Evaluation of personalized oral hygiene education on clinical attachment level in periodontal patients stage I/II/III. Evaluation of personalized oral hygiene education on the psychological determinants described by the Health Action Process Approach (HAPA) and the mediating role of these psychological determinants in oral hygiene habits and clinical parameters in periodontal patients stage I/II/III.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Control group: Dental model<br>Patients diagnosed with periodontal disease stage I/II/III | Behavioral: Control group: Dental Model<br>* - Patients receive a demonstration of plaque control methods (modified Bass dental brushing technique and the use of the electric toothbrush) using a dental model.<br>|
| Computer-assisted teaching format group<br>Patients diagnosed with periodontal disease stage I/II/III | Behavioral: Computer-assisted teaching format group<br>* - Patients receive a Powerpoint presentation containing:<br>|
| Plaque-disclosing group<br>Patients diagnosed with periodontal disease stage I/II/III | Behavioral: Plaque-disclosing group<br>* - Patients place a few drops of a plaque-disclosing solution on the tongue and run the tongue over all the teeth and gums. With the aid of a hand mirror, patients can observe the stained plaque residue on their teeth<br>|
| Intra-oral Camera group<br>Patients diagnosed with periodontal disease stage I/II/III | Behavioral: Intra-oral camera group<br>* - An ACTEON Soprocare® intraoral camera is used during the examination and explanation of oral hygiene strategies.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of the plaque index | Plaque Index (Loë and Silness, 1963): Six surfaces per tooth (buccal, mesio-buccal, disto-buccal, lingual, mesio-lingual and disto-lingual) are examined in every permanent tooth (except for third molars). Each tooth is assessed with a score between 0 and 3. 0 : absence of dental plaque 1 : plaque disclosed after running the periodontal probe along the gingival margin 2: visible plaque; absence of plaque in the interdental spaces 3: abundant plaque; presence of plaque in the interdental spaces | 3 months | 
| Evaluation of the gingival index | Gingival Index (Loë 1967): Six surfaces per tooth (buccal, mesio-buccal, disto-buccal, lingual, mesio-lingual and disto-lingual) are examined in every permanent tooth (except for third molars). 0: absence of visual signs of inflammation 1 : slight change in color and texture o 2: Visual inflammation and bleeding tendency from the gingival margin right after a periodontal probe is briefly run along the gingival margin 3: Overt inflammation with tendency for spontaneous bleeding | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of probing pocket depth | Probing pocket depth (distance from the top of the marginal gingiva to the bottom of the pocket) | 3 months | 
| Evaluation of the gingival attachment level | Gingival attachment level (distance separating the cemento-enamel junction from the bottom of the pocket) | 3 months | 
| Psychological determinants of the HAPA (Health Action Process Approach) | Change in the psychological determinants of the HAPA questionnaire adapted to oral health, using a 7-point Likert scale from strongly disagree (1) to strongly agree (7) | 3 months |
