An oral care programme for adults- Evaluation after 15 years

The present retrospective analysis sought to investigate the impact of the oral care programme (OCP) for adults provided at the Department of Conservative and Preventive Dentistry, Justus-Liebig-University of Giessen, Germany, on oral health parameters. The OCP was modular and included oral hygiene instruction/professional toothcleaning, nutrition counselling, fluoridation and re-motivation. From 1999–2014, data from 1665 patients (55.1% female, 44.9% male; median age 33 years, range 15;80) were available. Type/date of modules, % of proximal sites with plaque (PP) and with bleeding after probing (PB) and D(3/4)MFT/D(3/4)MFS were recorded. PP and PB values are given as median (min;max). Overall, 60.2% of the patients attended the OCP once, 19.1% twice, and 20.7% ≥ three times. Initially, PP/PB were 0.68(0;1)/0.08(0;1) resp. decreasing at visit two (0.62(0;1)/0.07(0;1) resp.; p≤0.001 each) with no further improvement over next visits. Patients with poor oral hygiene improved, but those with good oral hygiene worsened (p≤0.001 each). Shorter intervals between visits were more effective than longer intervals. Attendance patterns changed significantly over the years: earlier, patients attended more visits with different modules; later, patients preferred the oral hygiene module and the intervals between visits lengthened. Prevalence and incidence of caries was associated with higher PP levels. Attendance patterns changed over time and had a significant impact on the outcome of the OCP. The improvement of oral hygiene was limited and occurred within the first two visits; repeated sessions maintained this improvement. The results indicate the need for new strategies improving patients’ skills for efficient hygiene techniques.
