Cluster randomized control trial of nursing home residents' oral hygiene following the Mouth Care Matters education program for certified nursing assistants.

AIMS: The purpose of this study was to determine if the number of certified nursing assistants (CNAs) trained with the Mouth Care Matters (MCM) oral health educational program had an impact on nursing facility (NF) resident oral health. MATERIALS AND METHODS: Three NFs participated in a cluster randomized control trial. In NF-A: all CNAs were offered the MCM program, NF-B: 3 CNAs were offered the MCM program, and NF-C: Control (no CNAs were offered the MCM program). Demographic information, systemic health data, and oral health data at baseline, 3-month, and 6-month intervals were collected and analyzed using Kruskal-Wallis, Wilcoxon signed-rank and Wilcoxon rank-sum tests. A total of 24 dentate residents participated in this study. Plaque control record scores for NF-A were significantly reduced compared to NF-B and NF-C (P < .001 and P = .002 respectively) and gingival bleeding index for NF-A were significantly reduced compared to NF-B and NF-C (P = .002 and P < .001 respectively). CONCLUSION: Increasing the number of CNA's trained in the Mouth Care Matters educational program positively impacted NF residents' oral hygiene.
