Objectives:
This study aimed to explore factors influencing satisfaction with medical services among medically underserved populations at the free medical clinic, providing data to improve free medical services for these populations.
Methods:
We employed a descriptive correlational study design involving 112 individuals (aged 19 years and older) from medically underserved populations who visited the clinic. Data were collected through face-to-face surveys from September to October 2023, and statistical analyses (t-tests, analysis of variance, Pearson correlation, and hierarchical multiple regression) were used to identify key predictors of satisfaction.
Results:
Perceived support from healthcare providers emerged as the strongest predictor ofsatisfaction with medical services, demonstrating a significant positive association. While socialsupport was positively correlated with perceived support from healthcare providers, it did not independently predict satisfaction.
Conclusion
These findings underscore the importance of healthcare provider and social supportin increasing satisfaction with medical services among medically underserved populations.Developing tailored healthcare programs and specialized healthcare provider training are essential strategies to improve healthcare access and outcomes for these vulnerable groups.

PURPOSE:
The purpose of this clinical study was to evaluate the extent of intraoral occlusal adjustment required for zirconia crowns designed with a dynamic jaw motion tracking method compared to a conventional approach.
MATERIALS AND METHODS:
Fifteen patients needing zirconia crown restorations in the anterior or posterior regions participated in this study. Following tooth preparation, dynamic jaw motion tracking records were gathered using a tracking device. These records were imported into computer-aided design software and aligned with scanned upper and lower jaw data to design each crown's occlusal surface. Two crowns were fabricated for each patient: one using motion tracking data and another without it. Crowns were scanned pre- and post-adjustment following standard protocols. The scanned data were analyzed with 3D inspection software to calculate occlusal adjustments in the segmented occlusal area as root mean square values, with a paired t-test used for statistical analysis (α = 0.05).
RESULTS:
Crowns designed with motion tracking data required significantly less intraoral occlusal adjustment than those designed conventionally (P = .028).
CONCLUSION
Dynamic jaw motion tracking in crown design reduces the extent of intraoral occlusal adjustment, potentially enhancing clinical efficiency.
