Short-term effects of hygiene education for preschool (kindergarten) children: a clinical study

AIM: To evaluate the outcomes of short (15 minutes) oral hygiene vs. hand hygiene education for preschool children 4 weeks after these interventions. MATERIALS AND METHODS: Sixty-one preschool children (age range 4-6 years) attending four kindergarten classes participated in a 15-minute health education programme on the importance of body cleanliness for general health. In addition, specific instructions on oral hygiene were provided for two randomly selected classes (30 children), while the remaining two classes (31 children) were given instruction of hand and nail cleaning. The oral hygiene status was assessed usingthe plaque control record (PCR). The cleanliness of the hands and fingernails was determined using a hand hygiene index (HHI) and a nail hygiene index (NHI). All three parameters were assessed before the intervention as well as 4 weeks thereafter. RESULTS: Four weeks after education, the PCR had improved for all children from 79.95% to 72.35% (p < 0.001). The NHI had improved from 74.91% to 61.71% (p < 0.001). In addition, the mean PCR of the children given oral hygiene instruction decreased from 83.67% to 72.40%, while the mean PCR of the children given hand and nail cleaning instruction decreased from 76.23% to 72.29% (interaction effect 'time x type of instruction': p = 0.044). Girls' PCR improved significantly more than boys' PCR (Girls, 80.98 vs. 69.71; boys, 78.33 vs. 75.31; p = 0.021). CONCLUSIONS: The results of the study show that even a short, school-based educational intervention at an early age may affect children's oral health promotion significantly. Teachers should, therefore, be encouraged to educate children from an early age about oral hygiene promotion.

Changing the Face of Traditional Education

At large, research universities, a common approach for teaching hundreds of undergraduate students at one time is the traditional, large, lecture-based course. Trends indicate that over the next decade there will be an increase in the number of large, campus courses being offered as well as larger enrollments in courses currently offered. As universities investigate alternative means to accommodate more students and their learning needs, Web-based instruction provides an attractive delivery mode for teaching large, on-campus courses. This article explores a theoretical approach regarding how Web-based instruction can be designed and developed to provide quality education for traditional, on-campus, undergraduate students. The academic debate over the merit of Web-based instruction for traditional, on-campus students has not been resolved. This study identifies and discusses instructional design theory for adapting a large, lecture-based course to the Web.

The Prevalence and Focus of Medical Education Fellowships Across North America

Medical institutions have established medical education fellowships to equip faculty to meet the challenge of constant educational change and to empower faculty to assume programmatic leadership roles in medical education. The purpose of this study was to determine the prevalence and focus of these programs. [See PDF for complete abstract]
