About

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.

Full description

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.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

120 participants in 3 patient groups

Conventional Method (CM)

Active Comparator group

Description:

Individuals in this group receive instructions on oral care after initial periodontal treatment from the physician (SG) who is familiar with the patient groups. The physician verbally explains the development of periodontal disease, its causes, symptoms, and the potential consequences of irregular oral care, using a brochure to reinforce these points.

Treatment:

Procedure: scaling root planing

Three-Dimensional Animation (3DA)

Active Comparator group

Description:

The video used in the study was created by DentalMaster (MD Stimulation Ltd) by combining their own footage (http://www.mdsimulation.com/). This video is divided into three parts, summarized below: * i. Overview of the causes and symptoms of periodontal disease (section 1) * ii. Treatment of periodontal disease and daily oral care practices for individuals (section 2) * iii.Consequences of periodontal disease (such as gingival recession and tooth loss) that individuals may face if periodontal diseases are not treated and if they do not perform regular oral care (section 3). In this group, patients watch the video together with the physician (SG), who is familiar with the randomized patient groups.

Treatment:

Procedure: scaling root planing

Behavioral: Three-Dimensional Animation (video1-2)

Behavioral: Three-Dimensional Animation (video 3)

Periodontal Disease Prediction (PDP)

Experimental group

Description:

The patients in the test group viewed sections 1 and 2 videos in the same manner as the 3DA group. However, unlike the 3DA group, they did not view section 3. Instead, they were shown estimates of their current condition and potential future periodontal tissue loss (gingival recession) for 1-5 years, 5-10 years, and 10-20 years (1). These projections were presented to the patients in three dimensions with PDP visualisation.

Treatment:

Procedure: scaling root planing

Behavioral: Periodontal Disease Prediction (PDP)

Behavioral: Three-Dimensional Animation (video1-2)
