Tooth we...

BACKGROUND Individuals with Mibyeong are difficult to identify. Although extensive research has attempted to introduce an easy and clear method for Mibyeong diagnosis, the indices used to categorize Mibyeong severity are unclear. We hypothesized that individuals with severe Mibyeong have reduced physiological function, thus activating homeostatic regulatory functions and inducing alterations in...

The present study assesses the validity and reproducibility of two occlusal indices for epidemiological studies--the Dental Aesthetic Index (DAI) and the Dental Health Component of the Index of Orthodontic Treatment Need (DHC-IOTN) for the identification of orthodontic treatment needs.
