Abstract: AIM: Insufficient awareness among clinicians regarding the performance of light-curing devices may lead to inadequate polymerization, which can ultimately compromise the long-term success of dental restorations. This study aimed to examine the radiant power of different light-curing unit (LCU) brands by using three types of radiometers in terms of clinic and LCU types, age, tip diameter, and LCU tip condition in the Aseer region. METHODS: LCUs were assembled from selected dental centers. LCU brands and data, including clinical dental age (<1, 1–3, and ˃3 years), nozzle state (intact, damaged, and presence of debris), and tip diameters (6–7, 8–9, and 10 mm), were recorded. The radiant power was categorized into ≤1000, 1000–1200, and >1200 mW/cm2, which were labeled as adequate, sufficient, and adequate and sufficient, respectively, and recorded with three brands of digital radiometers (Woodpecker, Ivoclar, and Rogin). Analysis of Variance (ANOVA) and t-test were performed to determine the difference between and within groups, with a significance value of <0.05. RESULTS: Among 132 LCUs surveyed and assessed, a significant difference in the radiant power of LCUs was observed between governmental and private dental clinics, particularly with the Ivoclar radiometer (p < 0.05). No significant differences in radiant power values were detected between the radiometers and the assessed LCUs' nozzle. Older LCUs demonstrated higher radiant power in the ≤1000 mW/cm2 category when measured with the Ivoclar radiometer. Differences in radiant power were noted on the basis of tip diameter and the presence of remaining bond and composite materials (p < 0.05). CONCLUSIONS: The assessed LCU brands recorded marginally sufficient radiant power values in governmental and private dental clinics. The Rogin radiometer consistently demonstrated increased radiant power values across LCU brands and intact tip conditions. Differences in radiant power were noted in terms of tip diameter and the remaining bond and composite materials.
