Effectiveness of an oral hygiene program for Brazilian orphans.

The aim of this study was to examine the effectiveness of a preventive oral hygiene program in a group of 7-11-year-old children living in an orphanage in Brazil. The program was based on professional tooth cleaning, as well as dental health information and oral hygiene instruction during a 6-month period. A total of 80 children were examined and 42 who had all first molars erupted were selected for the study. Clinical measurements were recorded at baseline and after 3 and 6 months. Assessment of the efficacy of the program was based on plaque and gingivitis. At the final examination, the mean percentage of surfaces without visible plaque was 36.2% in the experimental group and 15.1% in the control group. These values were also reflected in improved gingival health. The test group showed bleeding upon probing from less than 20% of their interproximal areas, compared to 50% in the control group (p < 0.01). The results of this study indicate improved oral health through the implementation of preventive programs among children who have never been exposed to preventive dental treatment and who are living under adverse social conditions.
