Summary
Girls with normal occlusion have better chewing function than those with Class II malocclusion. Temporomandibular disorder (TMD) symptoms also negatively impact chewing efficiency and ability.
Area of Science:
- Orthodontics
- Dental Health
- Temporomandibular Disorders
Background:
- Masticatory function is crucial for overall health.
- Class II malocclusion can affect oral function.
- Temporomandibular disorders (TMD) may impact chewing.
Purpose of the Study:
- To compare masticatory efficiency and ability in girls with normal occlusion versus Class II malocclusion.
- To examine the relationship between masticatory function and TMD signs/symptoms.
Main Methods:
- 183 girls (11-15 years) with normal occlusion (n=60) or Class II malocclusion (n=123) were studied.
- TMD signs and symptoms were assessed.
- Masticatory efficiency was tested, and ability was self-reported via visual analog scale.
Main Results:
- Normal occlusion group showed significantly better masticatory efficiency and ability.
- Reduced masticatory efficiency was linked to fewer occlusal contacts, larger overjet, and TMD symptoms like jaw clicking.
- 30% of masticatory efficiency variation was explained by regression analysis.
Conclusions:
- Masticatory efficiency and ability are influenced by occlusion type.
- TMD symptoms significantly affect masticatory function in adolescent girls.
