Clinical Trial Summary

The goal of this clinical trial is to learn about the influence of providing visual feedback on brushing technique and habits on oral health of patients undergoing periodontal treatment.

The main question[s] it aims to answer are:

• Is patients' oral health improved by providing visual feedback on their brushing technique using the smartphone brushing app?

• Is there behavioural change of patients based on this daily visual feedback? Participants will receive oral hygiene instructions after initial periodontal treatment and will be randomized in group 1, 2 or 3. Participants will be asked to

• fulfill a brushing diary with the time of brushing every day.

• come back for a check-up appointment every 3 weeks during the study to evaluate oral hygiene.

Researchers will compare manual toothbrush, electric toothbrush without daily personal feedback and electric toothbrush with daily personal feedback to see if visual feedback provide improved oral health

Description:

Periodontitis is gum disease with jawbone deterioration. Diagnosis is based on clinical examination: plaque score, pocket measurement (measuring the pockets or gum pockets around the teeth with a probe), gingival bleeding index (= bleeding after probing) and radiographic examination. Smoking, genetic factors, and systemic diseases such as diabetes, for example, are known risk factors for this condition. Treatment consists of a deep cleaning, where the tooth roots are freed of plaque and tartar under local anaesthesia, complemented by the necessary oral hygiene instructions. It is important that patients follow these oral hygiene instructions carefully at home and perform them daily, as the aim is to achieve optimal oral hygiene. Good oral hygiene is fundamental in the treatment of periodontitis (Arweiler et al, 2018).

Despite many patients undergoing the proposed professional treatment (deep cleaning), they are often insufficiently able to remove the dental plaque present on a daily basis. To optimise brushing efficiency, both behavioural change and improved brushing technique should be obtained at the patient level.

The primary aim of this randomised clinical trial is to improve patients' oral health by providing visual feedback on their brushing technique using the smartphone brushing app. The secondary aim of the study is to investigate possible behavioural changes of patients based on this daily visual feedback.

Patients requiring periodontal treatment will be recruited at the Department of Periodontology & Oral Implantology at Ghent University Hospital. Patients will be assigned to three groups by randomisation. In group 1, patients will receive oral hygiene instructions and a new manual toothbrush. In group 2, patients receive the same oral hygiene instructions and a basic electric toothbrush without daily personal feedback using the brushing application. In group 3, patients receive the same oral hygiene instructions and an electric toothbrush with daily personal feedback using the brushing app (Oral-B app). No raw study data will be transferred to Oral B. The only data that will be available to Oral-B is the data that will be included in the publication of this study (A1 article). The use of the app does not require registration of personal data. Brushing time, tooth surface cleaning and brushing pressure will be recorded. Patients will only complete the brushing time in the brushing diary.

Oral hygiene will be evaluated at the start and every 3 weeks during the study through a check-up appointment. Only the first (after 3 weeks) and the last check-up appointment (after 12 weeks) are standard protocol, the remaining appointments (after 6 and 9 weeks) are study-specific. Oral hygiene will be assessed by: plaque score, gingival bleeding index, brushing frequency and brushing duration. The full study will take 12 weeks. Pocket depth will be measured according to usual protocols, namely at intake and at the last check-up (after 12 weeks). The patient's brushing technique and frequency will be recorded through a brushing diary completed by the patient. Where necessary, oral hygiene can be adjusted during each sitting. The check-up after 3 weeks and 12 weeks with measurement of plaque scores, gingival bleeding index and pocket depth are part of the standard protocol for treating periodontitis and are therefore not study-specific. Monitoring after 6 and 9 weeks are study-specific. The primary goal will be evaluated by comparing plaque scores and gingival bleeding index at intake with those at the final check. The secondary goal will be evaluated by brushing frequency and brushing duration throughout the study course. All data collected will be pseudonymised.

Overview:

• Consultation 1 - at start:

o Standard treatment: Evaluation of oral hygiene Determination of clinical score: plaque score, gingival bleeding index Determination of pocket depth

o Study-specific treatment (duration: 10 minutes): Clinical photographs

• Consultation 2 - after 3 weeks:

o Standard treatment: Evaluation of oral hygiene and brushing frequency. Determination of clinical score: plaque score, gingival bleeding index

o Study-specific treatment (duration: 10 minutes): Clinical photographs

• Consultation 3 - after 6 weeks:

o Study-specific treatment (duration: 30 minutes ): Evaluation of oral hygiene + clinical photographs Determination of clinical score: plaque score, gingival bleeding index

• Consultation 4 - after 9 weeks:

o Study-specific treatment (duration: 30 minutes ): Evaluation of oral hygiene + clinical photographs Determination of clinical score: plaque score, gingival bleeding index

• Consultation 5 - after 12 weeks:

o Standard treatment: Evaluation of oral hygiene and brushing frequency. Determination of clinical score: plaque score, gingival bleeding index Determination of pocket depth

o Study-specific treatment (duration: 10 minutes): Clinical photographs

• Completion of the brushing diary by the patient:

• Brushing time, cleaning of tooth surfaces, brushing pressure, brushing technique, frequency and motivation

• 2x a day, 2 min per brushing
