“…Results indicate that 18% of analyzed units presented an inadequate light intensity (< 400 mW*cm-2). Similar results were obtained by Eren D et al, where values below recommended intensity constituted 10, 7% [7], as well as Alquria T et al, with 13% [13]. However, Madhusudhana K et al, reported an increase of up to 44% of units with inadequate intensities [31].…”

“…Light sources are available in four types: Halogen, Light Emission Diode (LED), Xenon Plasma Arc (PAC) and Laser [12]. Halogen and LED are the most used in private dental clinics [13,14]. Halogen lamps were introduced in the '70s [15] and were considered as standard units for several years [16].…”

“…On the other hand, LED units started to be used in the '90s [20], this use joints with semiconductors to generate light, emitting wavelengths from 450 up to 486 nm [3,11] with intensities ranging between 1000 to 2000 mW*cm-2. These units present a lifetime of about 100 hours [13,18] and can be presented as wire or wireless devices, they are noiseless due to no need for ventilation, with less weight, producing less heat [18], and allow less work time [21,24]. Therefore, LED devices replaced halogen units and up to date are the most used and commercialized [16].…”

Introduction: Light intensity emitted by the curing lamps represents an essential factor in the activation of photosensitive materials. The adequate supply of intensity, as well as the correct functioning of the device, it ensures a correct dental treatment. Objective: To know the light intensity, type, and fiber state of the curing lamps used in private dental offices in the city of Cuenca - Ecuador. Materials and methods: The cross-sectional descriptive study assessed the light intensity of 366 light-curing lamps from private clinics with the use of a Bluephase Meter II radiometer, besides the Likert-scale based evaluation of its type and condition. Data analysis was done with the software R v.3.2 and its interface R-Studio v.1.2. Results: Inadequate light intensities were observed in 18% of the total analyzed units. Inadequate light intensities corresponded at 46% of Halogen lamps, and 12% of LED units. Likewise, 17% of units presented fiber fracture, while 52% showed residues of biomaterials on it. The predominant diameter in the units was 8mm, representing 65% of the total of light-curing lamps analyzed. Conclusions: LED lamps presented adequate light intensities in higher proportion in comparison to halogen lamps. It was shown that the presence of fractures and residues decrease the intensity of the photocuring units. Furthermore, we indicate that a periodic control of the light-curing units is necessary to prevent future problems in oral treatments.

“…Their mean value was 862.3 mW/cm 2 [14]. Another study done in private clinics in cities Dammam and Khobar also found a higher mean intensity of LED light-curing units, which was 865.2 mW/cm 2 [15]. That difference in mean value could be due to higher maintenance in private clinics.…”

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.

“…4 A recent study done by Alquria et al, 2019 also showed trends of LED over QTH in private dental clinics. 11 One possible reason for the low usage of LED light could be the outdated knowledge of practitioners in Karachi, as LED lights were introduced at the end of the '90s and many practitioners are still not aware of their superior properties over blue light. 12 The biggest advantage of using LED units is their easy maintenance.…”

Aim:The aim of this cross-sectional study was to identify and analyze the attitudes and practices of general dental practitioners of Karachi, Pakistan while performing dental composite restorations. Material and methods:A self-applied questionnaire was furnished to 150 general dental practitioners. A total of 125 practitioners filled and returned the filled questionnaire. The questionnaire mainly enquired about the commercial brand of composite resin used, dispensing and curing methods, handling techniques, finishing/polishing practices, and discoloration complaints made by the patients (if any). The results were collected and analyzed statistically. Results:The response rate was 83% (n = 125). The results indicated that 80% (n = 100) of the respondents claimed that they use a single paste system and blue light for curing. The number of dentists who covered the lid of single paste composite after usage was 68% (n = 85), whereas 72% (n = 90) used transparent matrices after placement the final layer of the composite restoration. Majority of the practitioners preferred finishing discs 53% (n = 66), and 84% (n = 105) of the patients returned with the discoloration complaint after two years. Conclusion:Majority of the general dental practitioners in Karachi, Pakistan preferred single paste system, blue light for curing, and discs for finishing restorations. Most patients returned after two years with a complaint of discoloration. Clinical significance:The study is relevant clinically as it deals with the techniques used by general dental practitioners while performing composite resin restorations. The study highlights clinical practices which are in line with evidence-based dentistry and also with techniques adapted by dentists which are obsolete and require an update.
