About this study
Official title: The Study of Parental Toothbrushing Efficacy Assessment With Triple-Headed and Single-Headed Toothbrushes in Preschool Children With Developmental Disability: A Randomized Crossover Study
The Objectives
- To evaluate the efficacy of dental plaque removal between triple-headed and single-headed toothbrushes in preschool children with developmental disabilities through parental brushing
- To assess the parental satisfaction with triple-headed toothbrushes
Read the detailed description
This study was a single-blind, randomized crossover study. 24 Parents of children with developmental disabilities (DD) were invited to participate in the study. Baseline data including demographic information, plaque index, and dmft, were collected. Participants were randomly assigned to receive their first toothbrush, either a single-head toothbrush (Berman®; soft and flat bristles for preschool children) or a triple-head toothbrush (Dr. Barman's Superbrush®; soft and flat bristles, size 0-6 years). Parents received toothbrushing instruction via a video clip according to the randomly assigned sequence of toothbrush type. Parents were then allowed to perform toothbrushing for their children. The quality of toothbrushing performance for each sextant was evaluated by the examiner using a toothbrushing performance form. Overall toothbrushing time was also recorded.
All participants were advised to use their own toothbrush during the washout period. After a four-week washout period, participants crossed over to the alternate toothbrush type, and all procedures were repeated. At the end of the study, parents completed a satisfaction questionnaire regarding the triple-headed toothbrush.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Triple-headed toothbrushDevice
The triple-headed toothbrush has been introduced to enhance brushing effectiveness as a design of three sides bristles, with each head capable of cleaning the buccal, lingual, and occlusal surfaces simultaneously. It is particularly suitable for individuals with limited manual skills, such as those with physical and mental handicaps, young or preschool children, especially important for caregivers when patient cooperation during brushing is limited.The round-end design is beneficial for easier brushing, reducing time, and improving cleaning efficiency, as proven in numerous studies

What is being measured
The primary outcome is the main question the study is designed to answer.
Dental Plaque Reduction Score Assessed by the Greene and Vermillion Plaque Index
Dental plaque removal efficacy was assessed by the change in dental plaque scores measured using the Greene and Vermillion Plaque Index (score range: 0-3). Dental plaque was disclosed using Disclosing PCA 260 Liquid Solution (Curaprox, Switzerland) and evaluated on the labial/buccal and lingual/palatal surfaces of six primary teeth (teeth no. 51, 55, 65, 71, 75, and 85). Dental plaque scores were recorded immediately before and immediately after parent-performed toothbrushing using either a triple-headed toothbrush or a single-headed toothbrush, according to a randomized crossover design. The outcome measure was calculated as the difference between pre-brushing and post-brushing plaque index scores for each toothbrush type. Mean plaque score changes were compared between toothbrush types. A randomized crossover design with a four-week washout period was used to minimize carryover effects. Brushing time (in seconds) was recorded as a secondary parameter to support interpretation of pla
Measured: 4 weeks per participant
Secondary outcomes (1)
Parental Satisfaction With the Use of a Triple-Headed Toothbrush
Parental satisfaction with the triple-headed toothbrush was assessed using a self-administered satisfaction questionnaire completed after parents used the triple-headed toothbrush to brush their child's teeth.
The questionnaire consisted of two sections. The first section collected parent demographic information, including age, sex, educational level, and relationship to the child with developmental disability. The second section assessed overall satisfaction with the triple-headed toothbrush, including ease of use, perceived effectiveness, and overall acceptance. Satisfaction responses were summarized using descriptive statistics.
Measured: 4 weeks per participant
