“…particularly at the critical wavelength of 440 nm falling within the typical emission range of LCUs. [28][29][30] Blue light penetrates the ocular medium and is absorbed by the retina, carrying the risk of causing rapid and irreversible harm to the retinal tissue. 30 It is widely believed that prolonged exposure to even low levels of blue light could accelerate the aging and degeneration of the retina, potentially worsening age-related macular degeneration.…”

BackgroundProper light curing is crucial for the success of restorative dentistry and to bond brackets to teeth, yet the responsibility is often delegated to dental assistants (DAs). This study assessed the proficiency and maintenance protocols of DAs when using light‐curing units (LCUs) in Saudi Arabia.MethodsSelf‐administered questionnaires were distributed to practicing DAs. The questionnaire contained sections on knowledge, adherence to best practices, and how to maintain the LCU. Demographic data were collected as well. Descriptive statistics and linear regressions at a significance level of (p = 0.05) were conducted to identify any relationships that influenced the DAs' LCU knowledge, practice, and maintenance protocols.ResultsAmong the surveyed DAs, 66% were responsible for using the LCU during treatment, 16% used their fingers for support when light curing, 50% held the LCU tip 1–2 mm from the restoration during curing, and 51% did not have a specific maintenance protocol at their workplace. 70% did not know the output from the LCU, and their educational background correlated with knowledge (b = −14.42, p < 0.001). The type of institution type correlated with adherence to best practices (b = −13.65, p = 0.011), and level of knowledge and adherence to maintenance protocols showed a direct correlation (b = 0.002, p = 0.041).ConclusionsThe findings revealed that a significant percentage of the DAs who replied had insufficient knowledge and did not follow the best practices and maintenance protocols for the LCUs they were using. Their educational background and workplace factors influenced this knowledge gap, while the absence of a maintenance protocol and suboptimal practices were associated with the type of institution.Clinical SignificanceTo maintain the best practice, clinicians and institutions should improve the education and training of DAs. Otherwise, inadequate light curing by the DAs may jeopardize the long‐term success of many dental procedures.

“…[ 118 ] The efficacies of CAs were further validated in three‐component photoinitiating systems under the irradiation of an ion laser at 514 nm (100 mW cm −2 ). [ 115 ] Considering that the currently used clinical curing lights emit blue light, which would cause severe ocular pathologies due to cumulative blue light exposure, [ 121 ] the discovered green‐light‐sensitive CA could serve as an alternative co‐initiator in dental resin to prevent or reduce the risk of retinal damage. Despite the development of near‐infrared light‐curing dental restoration materials, [ 122 ] which relied on the application of upconversion nanoparticles (UCNPs), the incorporation of additional UCNPs necessitates a thorough development of the composition of dental restoration materials due to the altered photopolymerization performance resulting from the transparency of dental resin.…”

Rapid manufacturing of medical devices during unforeseen pandemics is imperative. In striving for manufacturing efficiency, photopolymerization has emerged as a viable approach for diverse healthcare applications in recent decades. Photopolymerization‐based 3D printing offers significant potential with a range of biocompatible materials (e.g., poly(ethylene glycol), cellulose, etc.) while minimizing waste generation. However, prevalent commercial photoinitiators used in this process are synthetic and environmentally unfriendly. Therefore, the naturally occurring and derived photoinitiators have drawn tremendous research interest due to their bioactivities and inherent environmental safety. This review comprehensively outlines the medical applications implemented by these photoinitiators, highlighting their inherent photoinitiation abilities. Moreover, it delves into the impact of substituent effects on the photoinitiation abilities of naturally derived photoinitiators.

“…One of the most common whitening techniques involves applying a solution containing 25–40% hydrogen peroxide to the teeth’s surfaces. Halogen curing lights, LEDs, diode lasers, argon lasers, and plasma arc lamps are just some of the blue-light-producing units used in tooth bleaching, which have been developed to improve the activation of hydrogen peroxide in a shorter amount of time and thus produce more desirable cosmetic results [ 30 , 31 , 32 ]. For this reason, blue light is crucial in contemporary dental care.…”

Light is an emerging treatment approach that is being used to treat many diseases and conditions such as pain, inflammation, and wound healing. The light used in dental therapy generally lies in visible and invisible spectral regions. Despite many positive results in the treatment of different conditions, this therapy still faces some skepticism, which has prevented its widespread adoption in clinics. The main reason for this skepticism is the lack of comprehensive information about the molecular, cellular, and tissular mechanisms of action, which underpin the positive effects of phototherapy. However, there is currently promising evidence in support of the use of light therapy across a spectrum of oral hard and soft tissues, as well as in a variety of important dental subspecialties, such as endodontics, periodontics, orthodontics, and maxillofacial surgery. The merging of diagnostic and therapeutic light procedures is also seen as a promising area for future expansion. In the next decade, several light technologies are foreseen as becoming integral parts of modern dentistry practice.
