Interactive Power Toothbrush With or Without App vs Manual Toothbrush

The Effects of Interactive Powered Toothbrush With Application-assisted on Plaque, Gingivitis and Gingival Abrasion: A Randomized Controlled Clinical Trial.

It has been suggested that interactive power toothbrushes (PTBs), developed in recent years, provide more successful results in plaque control and effective use of brushing time by enabling patient collaboration and self-treatment, thanks to the application features associated with mobile phones. Interactive PTB synchronized with smartphones, including real-time feedback, session length, applications that prevent excessive brushing force, and focus brushing on specific areas with position detection technology, increases the brushing performance by increasing oral hygiene motivation.

Studies report that both power and manual toothbrushes cause gingival abrasion, a localized reversible lesion of the epithelium. While the opinions about the cause of gingival abrasion are not clear yet, the discussions regarding brush strength yet continue. While it is possible to control the interactive PTB force thanks to the mobile application, it is known that these high-speed rotating brushes control plaque effectively, but there is not enough evidence about its effect on gingival abrasion.

The primary purpose of this clinical study is to determine whether interactive PTB with application feature provides an additional benefit on plaque removal efficacy and reduction of gingival inflammation. In addition, this study aims to determine the effect of interactive power toothbrush with application on gingival abrasion by comparing it to interactive PTB without application and manual toothbrush. The study's null hypothesis in terms of gingival abrasion is that interactive PTB do not show a significant difference from other brushing methods.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Oral-B Genius® 8000 power toothbrush with Cross Action brush head with smartphone app for 8 weeks; Interactive PTB with Bluetooth® 4.0 connectivity smartphone app with Cross Action brush head using visually position detection feature. A triple pressure control system stops vibration, gives a visual warning, and reduces rotation speed in Daily Cleaning Mode-1.	Device: Oral-B Genius® 8000 power toothbrush with CrossAction brush head with smartphone app(Procter&Gamble,Ohio, USA); All the participants were asked to brush with fluoride toothpaste (Pro-Expert Professional Protection- Ipana, Gross-Gerau, Germany) with a pea-sized amount (0.25 g) of the toothbrushes, which were given oral and applied instructions for use, twice a day in the morning and evening. The installation and operation of the toothbrush application (app) on the smartphone was activated in the PTB with the app group
Active Comparator: Oral-B Genius® 8000 power toothbrush with CrossAction brush head without smartphone app for 8 weeks; PTB without Bluetooth® 4.0 connectivity without smartphone app with Cross Action brush head without using visually position detection feature triple pressure control system stops vibration, provides visual warning and reduces rotation speed. The group was asked to use PTB with daily cleaning mode 1 and brush head, but without using the Bluetooth app (without using the position detection system).	Device: Oral-B Genius® 8000 power toothbrush with CrossAction brush head without smartphone app(Procter&Gamble,Ohio, USA); All the participants were asked to brush with fluoride toothpaste (Pro-Expert Professional Protection- Ipana, Gross-Gerau, Germany) with a pea-sized amount (0.25 g) of the toothbrushes, which were given oral and applied instructions for use, twice a day in the morning and evening. The installation and operation of the toothbrush application (app) on the smartphone were not activated in the PTB without the app group.
Active Comparator: Manual toothbrush: Oral B ClinicLine Pro-FlexSoft (Procter&Gamble,Ohio, USA) for 8 weeks; They were instructed to brush according to the Modified Bass technique.	Device: Oral B ClinicLine Pro-FlexSoft (Procter&Gamble,Ohio, USA); All the participants were asked to brush with fluoride toothpaste (Pro-Expert Professional Protection- Ipana, Gross-Gerau, Germany) with a pea-sized amount (0.25 g) of the toothbrushes, which were given oral and applied instructions for use, twice a day in the morning and evening. They were instructed to brush with the Modified Bass technique.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Turesky modification of the Quigley-Hein Plaque Index (QHPI-TM) index measurement	Tooth surfaces stained with Mira-2 Toneblue® were evaluated with six different scores: Score 0 = No plaque, Score 1 = Plaque stains on the cervical edge of the tooth, Score 2 = A thin, continuous strip of plaque (up to 1 mm) at the cervical edge of the tooth, Score 3 = band of plaque wider than 1 mm but covering less than one-third of the dental crown, Score 4 = Plaque covering at least one-third but less than two-thirds of the dental crown, Score 5 = Plaque covering two-thirds or more of the dental crown.	2 weeks

Bleeding on marginal bleeding index (BOMP) index measurement	The presence/absence and amount of bleeding were graded on a 0-2 scale within 30 seconds of probing by probing the gingival margin at an angle of approximately 60 to the long axis of the tooth (0 = no bleeding, 1 = punctate bleeding, 2 = excessive bleeding).	2 weeks

Staining with Mira-2 Toneblue® to detect the gingival abrasion scores	Blue or purple visible abrasions were classified by measuring with a Williams periodontal probe placed along the long axis of the lesions ("small" if ≤2 mm, "moderate" if ≥3 mm and ≤5 mm, and "large" if >5 mm).	2 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Brushing times	The records in PTB group without-app and MTB were obtained with digital timer. In contrast, these records were obtained at the last appointment of the study; in Group PTB-A, the last brushing time records were sent to the researcher via e-mail by using the integral timer of the toothbrush, which is a feature of the mobile application.	8 weeks
Questionnaire	Questionnaire was applied to the participants including post-brushing pain/tenderness, cleaning capacity, manageability, and willingness to purchase via Visual Analogue Scale. Subjects were asked to mark a point on a 10 cm long uncalibrated line, with both ends interpreted as negative (left) or positive (right) ends.	8 weeks
