This study found that while high neuroticism is linked to lower oral quality of life before treatment, removable partial dentures significantly improve it. Prosthetic rehabilitation enhances satisfaction even in neurotic patients.
Area of Science:
- Oral health
- Psychology
- Prosthodontics
Background:
- Neuroticism can influence patient perception of oral health.
- Understanding this link is crucial for effective prosthetic treatment.
Purpose of the Study:
- To investigate the relationship between neuroticism and oral health-related quality of life (OHRQoL) before and after prosthetic treatment.
- To assess treatment efficacy in improving OHRQoL, particularly in relation to neuroticism.
Main Methods:
- Prospective cohort study of 63 patients receiving removable partial dentures (RPDs).
- Assessed OHRQoL using the Oral Health Impact Profile (OHIP-J) and neuroticism using the NEO Five-Factor Inventory (NEO-FFI).
- Statistical analyses included Spearman's correlation, Wilcoxon signed-rank test, and logistic regression.
Main Results:
- Higher neuroticism scores correlated with poorer OHRQoL before treatment (r=0.41, P=0.001).
- This association disappeared after prosthetic treatment (r=0.07, P=0.566).
- Neuroticism and baseline OHRQoL significantly impacted treatment efficacy.
Conclusions:
- Prosthetic rehabilitation with RPDs significantly improves OHRQoL in patients with high neuroticism.
- Oral rehabilitation can lead to improved patient satisfaction, even in individuals prone to higher neuroticism.
