Methods From March to October 2021, oral health education and behavioral interventions based on the Plan-Do-Check-Action (PDCA) cycle were carried out for second-grade children in a township school in Guiyang City for 6 months. The changes in oral health cognition, behavior habits and oral hygiene status of the children were observed in 3 months and 6 months after intervention. Results At the baseline survey, the total awareness rate of oral health knowledge, the rate of self-reported good behavior habits, plaque index and caries status value were 48.1%, 52.7%, 1.86±1.12, 1.53±0.62, respectively, which were 81.3%, 75.6%, 0.94±0.67, 1.39±0.68 in three months after intervention, and the difference was significant (χ2=175.072, 123.768, t=8.800, 2.381,P<0.05). At six months, the total awareness rate of oral health knowledge and the rate of self-reported good behavior habits were 76.9% and 71.2%, respectively, which were significantly different from those in three months after intervention(χ2=4.170, 5.193, P<0.05).The plaque index in six months after intervention was 1.07±0.73, which was not significantly different compared with that in three months. Conclusions Continuous intervention can effectively improve children's oral health awareness and promote the development of healthy behavior, but the maintenance of long-term effects needs to be continuously strengthened. Besides, it is suggested to improve the intervention program in the future from the perspective of organizational form and evaluation system. %U https://manu41.magtech.com.cn/Jwk_zgetbjzz/EN/10.11852/zgetbjzz2021-1669
