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 (n = 652), were randomly divided into a dentist group (n = 217), a teacher group (n = 216), and a control group (n = 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.

Oral Health Education Improved Oral Health Knowledge, Attitudes, and Plaque Scores in Thai Third-grade Students: A Randomised Clinical Trial.

PURPOSE: To compare students' knowledge, attitudes towards oral health, and plaque scores after oral health education sessions delivered by trained schoolteachers vs the control group. MATERIALS AND METHODS: The participants, comprising third-grade students in Amphoe Meuang, Nakhonphanom province (N = 435), were randomly divided into an experimental group (n = 216) and a control group (n = 219). Baseline data of the students' oral health knowledge, attitudes, and plaque scores were collected at the beginning of the study. The experimental group was given oral health education sessions by trained schoolteachers using a specifically designed student handbook, while the control group did not receive extra oral health education other than the national curriculum. The immediate post-test knowledge was evaluated after each session, and plaque scores were determined after the brushing session. After the oral health education programme ended, the experimental and control groups performed a monthly toothbrushing activity for 2 months. Final assessment of the students' knowledge, attitudes, and plaque score was done at the 3-month follow-up. RESULTS: The experimental group's oral health knowledge statistically significantly improved immediately after each session and was still statistically significant during the following three months. This improvement was also statistically significantly higher compared with the control group. The attitudes towards oral health care, foods related to caries, and dental visit improved. The plaque score of the experimental group was statistically significantly lower immediately post-brushing, but was not statistically significantly different at the 3-month follow-up compared with baseline. CONCLUSION: The children receiving oral health education provided by trained schoolteachers had statistically significantly greater oral health knowledge and more positive attitudes towards oral health than the children who had not received the programme. No statistically significant differences in plaque scores were found after 3 months.
