Assessment of the Effect of Periodontal Disease Prediction System on Oral Hygiene Motivation

Effects of Periodontal Disease Prediction System on Oral Hygiene Motivation in Patients With Periodontitis: A Prospective Randomised Controlled Clinical Study

The aim of this trial is to evaluate the effect of patient specific periodontal disease prediction (PDP) system, a part of motivational interview, (MI) on probing depth (PD), Rustogi modified Navy Plaque Index (RMNPI), and papillary bleeding index (PBI) scores in patients with periodontitis following non-surgical periodontal therapy.

A total of 120 participants included in our study and were then randomly assigned to three groups: a) conventional method (CM) (n=40), b) three-dimensional animation (3DA) (n=40), and c) Periodontal Disease Prediction (PDP) interaction (n=40). PD, PBI, and RMNPI values were recorded before periodontal therapy (T0). Following periodontal treatment, individuals in the CM group were instructed on oral hygiene via a model and brochure. Individuals in the 3DA group were informed using 3D video visuals. Participants in the PDP group were informed in a computer-based three-dimensional manner, providing projections of their current status and potential future gingival recessions after viewing the first and second parts of the 3D animation. Clinical periodontal measurements were repeated at 3, 6, and 12 months post-treatment. Data obtained after the study were analyzed using appropriate statistical methods. It was concluded that the proposed approach in this project could enhance periodontitis individuals' awareness about periodontal disease and personal oral hygiene especially for interdental cleaning over a long period. By this way, this PDP system can lead clinical benefits in reducing the recurrence of periodontal disease. It was hypothesized that patients in the PDP group could achieve significantly better plaque control and have lower bleeding scores compared to patients in the control groups, which include traditional oral hygiene motivation and three-dimensional video education.
