[Clinical study on guiding parents to promote oral health of pre-school children through self-made oral science video].

Abstract

Purpose: To evaluate the clinical effect of self-made oral science video on guiding parents to promote oral health of pre-school children, and to explore a more effective new technology in oral hygiene education.

Methods: One hundred and four 3-6 years old children with early childhood caries from Shanghai Xuhui District Dental Center were randomly recruited and divided into intervention group(n=52) and control group (n=52) during July to September 2022. At recruitment and 1 month after recruitment, the control group received routine oral health education, while the intervention group parents watched self-made oral health video and received routine oral health education. Plaque index (PLI), decayed missing filled tooth surface (dmfs) as well as oral health knowledge, attitude, practice(KAP) score of parents were compared between the two groups 1 and 6 months after recruitment.SPSS 26.0 software package was used for statistical analysis of the data.

Results: At 1 and 6 months after recruitment, the KAP score of intervention group （86.445±7.156, 85.694±5.880）was significantly higher than that of the control group [82.571(77.286, 88.142)，81.853±7.482]（P＜0.05）. The PLI of intervention group [2.014±0.403, 1.895(1.250, 2.100)] was significantly lower than that of the control group（P＜0.05）. There was no significant difference of dmfs between the intervention group and control group(P＞0.05).

Conclusions: As a new oral hygiene education technology, self-made oral science video is effective on improving oral health condition of pre-school children and the KAP condition of their parents.
