3D Printed vs. Milled Occlusal Splints in Dentistry

This crossover study aims to evaluate the wear comfort, retention, and stability of 3D-printed and milled occlusal splints in healthy subjects. The main question it aims to answer is: Research questions \- How do healthy subjects experience the wear comfort, fitting, retention and stability of a printed and milled occlusal splint? and how do clinicians experience the fitting, retention and stability of the splints? By systematically assessing self-reported outcomes, this research seeks to contribute valuable insights into the practical applications of both technologies. The findings may not only enhance our understanding of patient preferences but also guide future developments in the design and manufacturing of occlusal splints, ultimately improving patient care in dental practice.

Clinical Trial Recruitment and Retention Strategies for Family Members in the ICU

There is a need to identify strategies that improve the conduct of clinical trials involving family members of intensive care unit (ICU) patients. The purpose of the present study is to evaluate recruitment and retention strategies for clinical trials involving family members of ICU patients. 4 strategies (2 recruitment and 2 retention) will be tested. Investigators will integrate the strategies into three existing studies that involve family members of ICU patients. Participants will be randomized using a 2x2 factorial design. The co-primary outcomes are recruitment percentage (participants enrolled/participants approached) and retention percentage (participants completing follow-up/participants enrolled).

Restoration of Non-carious Cervical Lesions With Different Resin Composites and Universal Adhesive

patients with non carious cervical lesions suffer from dentin sensitivity and presence of cavitations and gingival recession. Restoring these lesions with different composites and evaluation of restorations every 6 months will be done to know the effect of different composite types and consistencies in retention of restorations of such lesions.
