Crossover study compared effectiveness of tripled and single headed toothbrush

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

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

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.
