Evaluating Knowledge and Practice Related to Light-Curing and Resin-Based Composites Polymerization.
Article in Oral health & preventive dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeDelivering high-quality restorative care requires clinicians to possess a solid understanding of light-curing units (LCUs) and resin-based composite (RBC) polymerisation. Despite growing research highlighting knowledge gaps among dental professionals, a disconnect remains between evidence-based recommendations and clinical implementation. This study assessed knowledge gaps and clinical practices related to LCUs and RBC polymerisation among dental students, general dentists, specialists and consultants in Saudi Arabia. MATERIALS AND
methodsA validated, electronic questionnaire collected data on demographics, LCU and RBC selection criteria, knowledge of polymerisation, and related clinical practices.
resultsAmong the 291 respondents, 63.9% of participants were unaware of their LCU irradiance, and 52.6% were not aware of the emission spectrum. Related clinical practices, maintenance routines, and infection control were suboptimal, with only 7.9% performed daily irradiance checks and 38.5% lacking a defined maintenance routine. Specialists demonstrated better knowledge than students and general dentists (P 0.05), yet knowledge gaps persisted across all groups. Notably, 81% of respondents expressed interest in continuing education on LCUs.
conclusionSignificant deficiencies in LCU selection, photoinitiator compatibility awareness, and maintenance practices were identified across all practitioner categories. Integrating competency-based education and standardised protocols is essential to improve polymerisation quality, ensure long-term restorative success, and safeguard patient care.
