Summary
Temporomandibular dysfunction (TMD) signs and symptoms did not significantly impact maximal bite force in complete denture wearers. Denture condition and TMD did not affect bite force in this study.
Area of Science:
- Dentistry
- Oral Health
- Biomedical Engineering
Background:
- Temporomandibular dysfunction (TMD) can affect bite force and muscle activity.
- Complete denture wearers may experience TMD, potentially influencing oral function.
Purpose of the Study:
- To compare maximal bite force between complete denture wearers with and without TMD.
- To investigate the influence of TMD and denture status on bite force.
Main Methods:
- A comparative study involving two groups of complete denture wearers (n=9 each): one with TMD and one healthy group.
- Assessment of dysfunction level using the Helkimo Index.
- Measurement of maximum bite force using a digital dynamometer adapted for oral conditions.
Main Results:
- The group with TMD exhibited lower mean bite force values compared to the healthy group.
- This difference in mean bite force was not statistically significant (p>0.05).
Conclusions:
- TMD signs and symptoms, along with denture structural conditions, did not significantly affect maximal bite force in complete denture wearers.
- Further research may be needed to explore subtle effects or different populations.
