Abstract

The Dental Health Component (DHC) is part of the Index of Treatment Need, besides the aesthetic index, that is used to determine orthodontic treatment need. The DHC objectively assesses orthodontic treatment need using five assessment components: missing teeth, overjet, crossbite, displacement of contact point, and overbite including open bite (MOCDO). The results of MOCDO assessment are then used to determine the grade (grades 1-5) of orthodontic treatment needed based on the worst component. We aimed to describe orthodontic treatment need based on malocclusion severity using DHC at the orthodontic specialist clinic RSKGM FKG UI from 2010 to 2014. This study used 52 pre-treatment dental casts and used the five components (MOCDO from DHC) to determine the grade. Starting with the most common grade, patients' orthodontic treatment needs were 55.8% grade 4 (need for orthodontic treatment), 30.8% grade 3 (borderline need for orthodontic treatment), 9.6% grade 2 (little need for orthodontic treatment), and 3.8% grade 5 (great need for orthodontic treatment). There were no cases of grade 1, which describes patients with no orthodontic treatment need. This study objectively concluded that most patients who visited the orthodontic specialist clinic had significant orthodontic treatment need (grades 4) and great need of orthodontic treatment (grade 5) was the least.
