Evaluating Knowledge and Practice Related to Light-Curing and Resin-Based Composites Polymerization.

Area of Science:

• Dental Materials Science
• Clinical Dentistry

Background:

• High-quality restorative care depends on understanding light-curing units (LCUs) and resin-based composite (RBC) polymerization.
• Existing research indicates knowledge gaps among dental professionals, impacting clinical practice.

Purpose of the Study:

• To assess knowledge gaps and clinical practices concerning LCUs and RBC polymerization.
• The study focused on dental students, general dentists, specialists, and consultants in Saudi Arabia.

Main Methods:

• A validated electronic questionnaire was used to gather data.
• Data collected included demographics, LCU/RBC selection, polymerization knowledge, and clinical practices.

Main Results:

• A significant percentage of participants (63.9%) were unaware of their LCU irradiance, and 52.6% lacked knowledge of the emission spectrum.
• Clinical practices, including maintenance and infection control, were suboptimal; only 7.9% performed daily irradiance checks.
• While specialists showed better knowledge than students and general dentists, gaps persisted across all groups. 81% desired further education.

Conclusions:

• Deficiencies in LCU selection, photoinitiator compatibility awareness, and maintenance were prevalent.
• Competency-based education and standardized protocols are vital for enhancing polymerization quality and restorative success.
• Addressing these gaps is essential for safeguarding patient care in restorative dentistry.
