Evaluating the Efficacy of Chewable Toothbrushes: A Scoping Review

Abstract

Introduction: The Chewable Toothbrush (CB) is a recent innovation in mechanical plaque removal methods. With its unique design, this tiny compressible brush can be used in both chewing and brushing actions without the need for toothpaste or water. Aim: To provide an overview of the indications, contraindications, advantages, and disadvantages of CBs. Furthermore, the present study aims to summarise the current evidence on the efficacy of plaque removal compared to powered or manual toothbrushes in all age groups and in both orthodontic and non orthodontic patients. It also aims to report the evidence on the ability of CBs to prevent dental caries. Materials and Methods: The electronic databases of ‘Google Scholar,’ ‘PubMed,’ ‘Cochrane Database,’ and ‘Science Direct’ were searched for all studies that evaluated the efficacy of CBs in removing dental plaque or controlling dental caries. The eligibility criteria included any study written in English, involving all types of populations without any restrictions. A total of 14 articles were identified and included in the present review. A data-charting form was utilised to extract relevant information from eligible studies. Results: A review of the current published studies revealed inferior efficacy for CB compared to the powered brush, with inconsistent findings compared to the manual brush. Additionally, CB has demonstrated promising caries prevention capabilities in most studies. Conclusion: Based on its indications, CB might be an appropriate oral hygiene tool in situations where manual toothbrushing is difficult to perform, such as in individuals with physical disabilities, reduced manual dexterity, and those who lack brushing motivation or the appropriate brushing technique. The use of CB could be beneficial in individuals with a high-risk of caries due to its unique anticaries properties. However, more research is required to confirm these findings.
