ABSTRACT

Interceptive orthodontic is an orthodontic treatment procedure that aims to minimize malocclusion's effect and decrease the need for more complex, high-cost treatment, eventually declining the need for corrective orthodontic treatment. Jakarta and Kepulauan Seribu have more than 763,666 primary school-aged children; thus, screening for the need for interceptive orthodontic treatment would be beneficial in identifying these children who may benefit from treatment. This study aims to investigate the need for interceptive orthodontic treatment and identify its related factors in 8-11 years old children in Jakarta and Kepulauan Seribu. This study was observational analytic with a cross-sectional design utilizing the Index of Interceptive Orthodontic Treatment Need (IIOTN). Each indicator was scored based on the subjects’ intra-oral conditions and then analyzed by the Spearman correlation test. Based on 2,020 subjects, it was found that 18.96% of subjects do not need orthodontic treatment, 59.36% need interceptive orthodontic treatment, and 21.68% need corrective orthodontic treatment. There was a significant correlation between the need for interceptive orthodontic treatment with parents’ income (r= -0.07; p= 0.02). IIOTN could be used as an interceptive orthodontic treatment screening instrument. More than half of the subjects require interceptive orthodontic treatment. Parents’ income is the only demographic factor related to the need for interceptive orthodontic treatment.
