Background/Purpose:
Despite the existing knowledge on osteogenesis imperfecta (OI), there is a notable lack of research focused on determining the optimal number and types of teeth that individuals with OI should keep to ensure effective chewing. This study aimed to identify variables influencing masticatory ability among patients with OI.
Materials And Methods:
A total of 37 patients with OI participated in the study. Data were collected through questionnaires and dental examinations. The questionnaire assessed sociodemographic information, oral habits, self-perceived health, and self-rated masticatory ability, utilizing 14 common Taiwanese food groups. Dental information was evaluated through clinical examinations. Statistical methods, including the Mann-Whitney U and Kruskal-Wallis tests, were employed to identify factors associated with self-rated masticatory ability. Subsequently, multiple logistic regression analysis was conducted to identify predictors of masticatory ability.
Results:
The multiple logistic regression analysis identified the number of posterior functional tooth units (P-FTUs) as a significant predictor of masticatory difficulty in patients with OI.
Conclusion:
Enhancing masticatory ability in patients with OI requires not only a sufficient number of natural teeth or fixed prosthetics but also a focus on the optimal arrangement and functionality of these dental supports.
