Abstract

Health Background: Tooth decay is a fairly common condition, causing many serious consequences for oral health as well as health in general. Tooth decay in young children can increase the risk of developing deviations in jaw structure, bite formation as well as future permanent tooth development and clinical treatment of tooth decay in children. At this age, it is very difficult and expensive. Objective: Assessment of Dental Caries Status in Children Under 48 Months at Preschools in Thanh An Commune, Ho Chi Minh City. Subjects and research method: children under 48 months old, through clinical examination and assessment of oral hygiene status, applying DI index of OHI S, classified into 3 levels: good, average, poor. Results: The rate of children with tooth decay was 63.9%; In which the common age for tooth decay is 36 to 48 months old (accounting for 64.9%). Only 11.7% of children achieved good oral hygiene (VSRM), while the average rate of VSRM was 24.4% and poor oral hygiene was 63.9%. The rate of tooth decay is highest in the group of children with poor dental hygiene (statistically significant difference with p < 0.05). The number of children's decayed teeth is 251 teeth, accounting for 63.9%; which is mainly in the lower jaw. Conclusion: The highest rate of tooth decay is in the group with poor oral hygiene, accounting for 98.7%, the highest rate of tooth decay is concentrated in the age group 36 to 48 months old (accounting for 55.4%). The molar group is the group most affected, especially the lower molar group. The rate of children achieving good oral hygiene is still very low, accounting for 17.3%. The rate of poor oral hygiene is quite high, accounting for 60.3%. Recommendation: There should be propaganda and education measures for parents about how to care for and take care of their children's teeth. In addition, there also needs to be measures to overcome the current tooth decay situation of children in the study.
