Comparative Study of Oral Health Education Given by a Dentist and Schoolteachers in Thai Grade 3 Students.

OBJECTIVES

To compare children's knowledge and attitudes toward oral health (OH) and plaque score after receiving OH education (OHE) from a dentist or trained schoolteachers.

MATERIALS AND METHODS

Third-grade students in Amphoe Meuang, Nakhon Phanom, Thailand ( = 652), were randomly divided into a dentist group ( = 217), a teacher group ( = 216), and a control group ( = 219). The students' OH knowledge, attitudes, and plaque scores before the intervention were collected as baseline data. The dentist and the teacher groups received additional OH education sessions by a dentist and trained schoolteachers, respectively. Their immediate post-test knowledge was evaluated after each session, and plaque scores were determined after the brushing session. All groups continued a monthly tooth brushing activity for two months. The final assessment was done at the three-month follow-up.

RESULTS

The students who received additional OHE by either a dentist or teacher demonstrated improved knowledge and attitudes towards OH, including plaque score. Interestingly, at the three-month follow-up, the knowledge score in the teacher group was significantly higher than in the dentist group. However, the dentist group had a significantly lower plaque score compared with the teacher group.

CONCLUSIONS

Additional OHE in school significantly improved students' OH knowledge and positive attitudes regardless of the provider. However, the teacher tends to have a greater impact on their students; thus after appropriate training, schoolteachers can be efficient OH educators, especially in the long term.
