Powered versus manual toothbrushes for plaque removal and gingival health amongst 55 and older individuals: A systematic review and meta-analysis.

OBJECTIVE

To compare manual and powered toothbrushes in older adults and to culminate available clinical evidence concerning efficiency with respect to plaque removal and reduced gingivitis.

BACKGROUND

Manual dexterity decreases with age, negatively impacting daily activities, including oral hygiene practices. Effective plaque control in this age group is directly related to nutrition and overall health. Therefore, developing oral health interventions tailored to the ageing population is essential.

MATERIAL AND METHODS

This systematic review was registered with PROSPERO (Registration No. CRD42023415876). Five electronic databases were searched to identify randomized controlled trials published from inception until March 2023. The risk of bias was assessed using the Cochrane Risk of Bias Tool. Meta-analyses were also performed for gingival, plaque, and bleeding indices.

RESULTS

A total of 2118 records were identified, and six eligible publications were retrieved. Comparison of Plaque Indices between powered and manual toothbrushes showed a Standard mean difference (SMD) of -0.10; 95% CI [-0.37, 0.18] (p = .38). Comparison of the gingival index and bleeding index between powered and manual toothbrushes showed an SMD of -0.28; 95% CI [-0.72, 0.16] (p = .22) and SMD of -0.03 [-0.38, 0.32] (p = .84), respectively.

CONCLUSION

According to the available literature, this study suggests the need for more streamlined research to support the superiority of either powered or manual toothbrushes in improving oral health (as measured by the indices) among the older population. The results will hence have significant reverberations for older adults looking to improve their oral hygiene practices.
