Purpose:
The purpose of this study was to evaluate differences in Oral Health-Related Quality of Life (OHRQoL) among orthognathic patients with different skeletal malocclusions before initiating orthodontic treatment.
Methods:
150 patients were evaluated for OHRQoL at the Oral and Maxillofacial Surgery Department at Boston University Goldman School of Dental Medicine. OHRQoL was measured using: (1) Oral Health Impact Profile-14 (OHIP-14) for generic OHRQoL; (2) Orthognathic Quality of Life Questionnaire (OQLQ) for condition-specific OHRQoL; and (3) the 12-item oral quality of life instrument (12-item OQOL) for generic OHRQoL. Cephalometric measurements were used to categorize facial types then two-sample t-tests and one-way ANOVAs were employed to analyze OHRQoL across groups.
Results:
OHIP-14, OQLQ, and 12-item OQOL baseline scores were statistically different between skeletal Class I, II, and III patients (p < 0.05), with Class II patients showing the highest scores. No significant differences were found between vertical patterns (p > 0.05).
Conclusion:
OHRQoL is different between skeletal Class I, II, and III patients with Class II patients reporting lower quality of life.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Oral Cavity
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
