A randomised controlled trial of a smartphone application for help oral hygiene

INTERVENTION: Behavioural Dental exams: visible plaque index; gingival bleeding index; probing depth; loss of clinical insertion; scaling and root planing; They will be held at Baseline, after 4 weeks, after two months. 28 control group 28 test group (mHealth intervention) Dental Scaling Device Other CONDITION: Gingivitis gingivitis; periodontitis; oral hygiene. ; Gingivitis ; Periodontitis ; Oral Hygiene Oral Hygiene Periodontitis PRIMARY OUTCOME: Primary outcomes:; We will observe the improvement in the periodontal parameters of the test and control groups, verified through the mean difference of the gingival bleeding index; from a variation of 5% in the pre and post‐intervention measurements. Primary outcomes:; We will observe the improvement in the periodontal parameters of the test and control groups, verified through the mean difference of the loss of clinical insertion, from a variation of 5% in the pre and post‐intervention measurements.; Primary outcomes:; We will observe the improvement in the periodontal parameters of the test and control groups, verified through the mean difference of the probing depth, from a variation of 5% in the pre and post‐intervention measurements.; Primary outcomes:; We will observe the improvement in the periodontal parameters of the test and control groups, verified through the mean difference of the visible plaque index, from a variation of 5% in the pre and post‐intervention measurements.; SECONDARY OUTCOME: Secondary outcome: ; We will observe the increase in knowledge about oral hygiene, checking the number of correct answers between tests of knowledge about oral hygiene, from a variation of 5% in the pre and post‐intervention measurements.
