“…About 52.78% of the students in our study also constrict the curing time to 20 s, but with no correlation to the intensity, although 18.21% cure their restorations for 30 s and 23.77% cure their restorations for 40 s also in no correlation to the intensity of the LCU. In 2019, in Punjab, India two-thirds of dentists did not use barriers for infection control on the light-curing tip, while only one-third of dentists did use barriers [9]. In comparison, 68.52% of our students answered yes on the question "Do you check the light cure tip before curing your restoration?."…”

“…Maintenance is required because with lack of monitoring VLC units' qualities diminish over time resulting from heat buildup within the unit, bulb frosting, tip contamination with remains of composite, and sterilization problems [7], [8]. When the LCU's intensity is lower than 400 mW/cm 2 , it means that the bulb is deteriorating and needs to be replaced [9].…”

AIM: The aim of this study is interpreting the dental student’s knowledge of light-curing units from different universities and colleges in Riyadh city and to evaluate the intensity of the light output of light-emitting diode (LED)-curing devices in dental school clinics in Riyadh, Saudi Arabia. METHODS: One hundred eighty-two visible light-curing (VLC) units were randomly selected to have their light intensity output evaluated using Demetron® L.E.D. Radiometer – Kerr among dental school clinics in Riyadh city. The university hospitals we visited are King Khalid University Hospital, King Saud bin Abdulaziz University Hospital, Dar Al Uloom University Hospital, Alfarabi colleges’ dental clinics, and Princess Nourah Bint Abdulrahman University Hospital. To evaluate the knowledge of dental students about light intensity output, a questionnaire was given to the students. RESULTS: Out of the VLC units, 22 units (12%) measured inadequate intensity, 91 units (50%) measured marginal intensity, and 69 (37%) measured adequate intensity. The statistical significance was up to p < 0.05, p = 0. Most students and interns did not think that light-curing unit intensity influenced the tooth pulp (55.8%) and also reported not know the minimum wavelength of light cure intensity (62%). CONCLUSION: A significant difference was found between the light cure intensities in universities. As for the students’ knowledge, the research revealed poor insight toward basic concepts of VLC units and its maintenance.

“…[ 20 21 ] Each layer has to be light cured for at least 20s to achieve proper degree of conversion[ 10 ] and to avoid negative repercussions of inadequate polymerization that include discoloration, sensitivity, and pulpal irritation. [ 3 5 , 6 22 , 23 ] In a clinical survey, Bansal et al [ 24 ] found that 54% of the 1000 tested devices gave output values <400 mW/cm 2 . On the contrary of this and in accordance with our findings, Soares et al [ 10 ] reported that only 2 of 22 tested LCDs produced irradiance values of <400 mW/cm 2 .…”

A BSTRACT Aim: The aim of this study was to test the irradiance values of different curing modes of commonly available light cure devices (LCDs). Materials and Methods: An in vitro investigation was carried out to compare the irradiance output of 10 brands of LCDs available in Saudi Arabia measured using a digital radiometer. Values were recorded for three time points when applicable (0, 10, and 20s). This technique was repeated five times for each LCD. Normal, high-intensity, and soft-start modes were evaluated for all brands with the features available. Irradiance values between brands were analyzed using one-way analysis of variance followed by Bonferroni method. Changes in irradiance between different time points were analyzed using one sample t test for normal and high-intensity modes and using paired t test for soft-start mode. All comparisons were carried out at 0.05 significance level. Results: The highest values were reported for Ortholux Luminous, Elipar DeepCure-S, Elipar DeepCure, and KaVo mini-LED with values above 1000 mW/cm 2 . All LCDs showed values above 600 mW/cm 2 . Three LCDs had high-intensity mode and only one device had soft-start mode. Changes over the different time points were not statistically significant exept for soft-start mode. Conclusion: All tested LCDs had irradiance values sufficient for adequate polymerization of resin composite. Only four of these are capable of curing bulk-fill composites.

A eficiência clínica de uma unidade de fotopolimerização é crucial para obter uma polimerização ideal e um resultado bem-sucedido. O objetivo deste estudo observacional foi avaliar e analisar a intensidade da potência luminosa das lâmpadas de fotopolimerização de clínicas odontológicas privadas na cidade de Cuenca, Equador. A intensidade da luz foi avaliada usando o radiômetro CK12024 (mede o tempo de cura até 2000). Foi classificado de acordo com os seguintes parâmetros: baixo desempenho (<300mw/cm2), desempenho regular (300 - 800 mw/cm2) e alto desempenho (>800 mw/cm2), em um tempo de 20 segundos e 40 segundos. Tabela em “Microsoft Excel”, para acompanhar todos os dados necessários: número da lâmpada, tipo de lâmpada, intensidade da potência luminosa em 20 segundos, intensidade da potência luminosa em 40 segundos, fratura da fibra ótica e resíduos de biomateriais na fibra ótica. Obteve-se como resultado que das 58 lâmpadas avaliadas, um percentual de 0,6% (n=1) do total de unidades de fotopolimerização tem baixo desempenho, 5,2% (n=3) tem médio desempenho e 93,1% (n= 54) deles tiveram um alto desempenho. A polimerização adequada é crucial para obter boas propriedades mecânicas e físicas e excelentes resultados clínicos. De acordo com os resultados obtidos no presente estudo, observa-se que a maioria das lâmpadas de fotopolimerização utilizadas em consultórios particulares na cidade de Cuenca tem um alto desempenho clínico.
