Evaluation of novel programs in health counseling – their effectiveness in the oral health of young children, and their acceptance by parents and professionals in public dental service.

Aim and design: To evaluate family-based health counseling for young children, and to study the significance of adding parental self-care or the training of professionals to the programs. The effectiveness and acceptability of the programs were evaluated by comparing two new programs with an earlier one. Subjects and methods: The study was carried out in Vantaa, which was divided into three study areas. The subjects consisted of children born in 2008, particularly fi rstborn children, while children born in 2006 formed the historical control. The fi rst of the new programs emphasized oral hygiene and use of fl uoride, and the second program focused on proper diet and use of xylitol. The main outcome measure was mutansstreptococci (MS) in the dental biofi lm of two-year-olds, and the opinions of parents and dental professionals were evaluated using questionnaires. Results: The programs found wide acceptance among dental professionals. There were no group-related differences found in the MS scores of the two-year-olds. However, all groups combined, father’s advanced level of education and child’s proper use of xylitol were associated with negative MS scores. In the opinion of parents, the oral healthcare guidance at least somewhat met their expectations. Conclusions: The present fi ndings suggest that providing training and support for professionals in health education is important. The addition of parental self-care to supplement programs aimed at young children does not improve the program, although it may improve parental readiness to change their own health habits. Counseling for families might be best carried out through a routine patient-centered program.

Effectiveness of cleaning and sanitizing procedures in controlling the adherence of Pseudomonas fluorescens, Salmonella Enteritidis, and Staphylococcus aureus to domestic kitchen surfaces

The effectiveness of cleaning and sanitizing procedures in controlling Staphylococcus aureus, Salmonella Enteritidis, and Pseudomonasfluorescens adhered to granite and stainless steel was evaluated. There was no significant difference (p > 0.05) in the adherence of pure cultures of these microorganisms to stainless steel. The numbers of P. fluorescens and S. Enteritidis adhered to granite were greater (p < 0.05) than the numbers of S. aureus. Additionally, the adherence of P. fluorescens was similar to the adherence of S. Enteritidis on granite surface. In a mixed culture with P. fluorescens, S aureus adhered less (p < 0.05) to stainless steel surfaces (1.31 log CFU.cm-2) than when in a pure culture (6.10 log CFU.cm-2). These results suggest that P. fluorescens inhibited the adherence of S. aureus. However, this inhibition was not observed in the adherence process for granite. There was a significant difference (p < 0.05) between the number of adhered cells before and after pre-washing for S. aureus on stainless steel and granite surfaces, and after washing with detergent for all microorganisms and surfaces. The efficiency of the cleaning plus sanitizing procedures was not significantly different (p > 0.05) between the surfaces. However, a significant difference was observed (p < 0.05) between the sanitizer solutions. Sodium hypochlorite and peracetic acid were more bactericidal (p < 0.05) than a quaternary ammonium compound. With regard to microorganisms, S. aureus was the least resistant to the sanitizers. These results show the importance of good cleaning and sanitization procedures to prevent bacterial adherence and biofilm formation.
