Could a national oral health promotion program improve the oral hygiene of persons attending special care establishments in France? Evaluation of a pilot program.

This study aimed to investigate the effectiveness of an oral health promotion intervention implemented in special care establishments by dentists trained online. Twenty-six dentists intervening in 27 French special care establishments undertook a standardised oral health promotion intervention, including a conference presentation for care staff and hands-on toothbrushing workshops. Oral hygiene status of the residents was performed at baseline and at 6 months, and were compared using the McNemar test. Mixed logistic regression was performed to identify the factors associated with an improvement of dental plaque removal. The oral health intervention was completed by 890 residents: 445 children, 373 adults and 72 elderly adults. At baseline, dental plaque was observed for 79.8% of the 797 dentate residents. Among the 691 dentate residents included in the final analysis, dental plaque removal was improved for 34%. Improvement in dental plaque removal was recorded more often for the group of 13 to 20-year-old residents (OR = 1.97; 95% CI = 1.15-3.38). The results indicate that this programme failed to significantly improve the dental plaque removal of the residents. More research is needed to understand the limiting factors of such interventions.
