Evolution of outpatient parenteral antibiotic therapy

The aim of this study was to evaluate clinically and microbiologically the effects of a preventive oral health program in a long-term care facility. A total of 116 dentate elderly residents agreed to participate, and half of them were included in an experimental group. Almost all of the residents were mentally or physically handicapped, and many were dependent on care-givers for daily living activities. Oral examination and microbiological sampling were performed at baseline and 18 months later. The experimental group benefited from a preventive program, including an oral hygiene course for the health care providers and regular recalls by dental hygienists of the residents. After 18 months, the plaque indices were statistically similar to those at baseline in both groups. Mutans streptococci counts and active root caries at 18 months were lower compared to baseline in the experimental group but did not change significantly in the control group. Thus, it seems that, while the preventive program failed to decrease plaque indices, it was effective in reducing mutans streptococci colonisation and caries prevalence.
