The efficacy and effectiveness of electric toothbrushes in comparison to manual toothbrushes lead to superior full-mouth and interproximal plaque removal and reduction of gingivitis, periodontitis and dental caries. Additionally, the use of an irrigator has been shown to improve the overall oral health. The aim of this study was to design and develop a utility model for the combined effect of the oral irrigator and tooth brush for maintaining oral health. The design of the modified toothbrushing unit comprises of an electric toothbrush and an oral irrigator. This was achieved by removing the electric toothbrush head to place a drill in the centre of the brush head for the insertion of irrigator head. The irrigator which was attached to a 50 ml water container with a detachable irrigator head powered by a 12 V external battery source was used to pump the water. The outcome was that a multifunctional working model combining the electric tooth brush and oral irrigator is designed successfully. Aqua Brush can be incorporated into the regular oral hygiene regimen making it convenient for the patient as it can be used as a single brushing unit and/or with the added irrigation enhancing the maintenance of oral hygiene.
