Abstract

Introduction. The high prevalence of malocclusion in Indonesia, approximately 80%, highlights a significant public health issue. Malocclusion is an abnormal arrangement of the teeth or jaws. This problem is compounded by the limited number of orthodontists, emphasizing the need for preventive or interceptive orthodontic treatments. Developing an index to measure the need for interceptive orthodontic treatment is crucial for screening and early detection of malocclusion in children during the mixed dentition period. Purpose. The purpose of this study is to evaluate the validity of the Indonesian Interceptive Orthodontic Treatment Needs (IIOTN) index for assessing malocclusion in children with mixed dentition. Method. A qualitative study was employed to assess the validity of a questionnaire. Four domains (primary teeth, anterior and posterior permanent teeth and occlusion) were constructed. Data validity was measured by four expert reviews. Result. Expert opinions and reviews were provided for each domain to prevent or lessen malocclusion in permanent teeth, with a particular focus on the correlation with occlusion development in children. These studies supported the face validation of the index for measuring interceptive orthodontic treatment need. Conclusion. The Indonesian IOTN index could be used to screen for malocclusion requiring interceptive orthodontic treatment. This index can be broadly applied within the community to reduce the impact on quality of life and self-confidence in children. Future research should focus on longitudinal studies to further validate the Indonesian IOTN index and its applicability in diverse populations.
