“…This suggests that plasma shielding on composite surfaces for the shorter 150-ns Er:YSGG laser pulses greatly restricts the ablation rate and reduces efficiency. Previous studies have indicated that shorter laser pulses are advantageous for reducing thermal damage to peripheral dentin [28,29], however if the pulses are too short plasma shielding reduces the ablation rate and efficiency and it is only necessary to reduce the pulse duration to near the thermal relaxation time which is on the order of tens of microseconds for enamel and dentin at erbium wavelengths to minimize thermal damage [30].…”

New diode-pumped solid state (DPSS) Er:YAG lasers have become available operating at high pulse repetition rates. These lasers are ideally suited for integration with laser scanning systems for the selective removal of dental decay and composite restorative materials from tooth surfaces. The purpose of this study was to determine if a DPSS Er:YAG laser system is suitable for the selective removal of composite from tooth surfaces. Relative ablation rates of composite and enamel were determined and composite was removed from tooth surfaces using a DPSS Er:YAG laser. Composite was removed very rapidly with ablation rates approaching 50-µm per pulse. A fluence of ~50 J/cm 2 appeared optimal for the removal of composite and damage to the enamel was limited to less than 100-µm after the removal of composite as thick as 700-800-µm; however, dentin is removed at similar rates to composite. The DPSS Er:YAG laser appears to be better suited for the removal of composite than conventional flash-lamp pumped Er:YAG lasers since composite is ablated at higher rates than dental enamel and the high pulse repetition rates enable greater selectivity while maintaining high removal rates.

“…The development of near-infrared transillumination for caries detection started around 1995 [103]. This method uses near-infrared wavelength interactions with the dental substance allowing visual discrimination between healthy and demineralized tissue [103,[117][118][119]. Fried et al demonstrated that dental enamel becomes highly transparent when illuminated with NIR light, while dentine scatters strongly the visible and NIR light.…”

“…Several studies have shown NIR to have higher sensitivity than BW to detect both proximal and occlusal caries and may be used for monitoring [122][123][124][125][126]. Over the past ten years, NIRT imaging was further examined for multiple indications including primary and secondary caries detection on occlusal and proximal surfaces, early caries monitoring, caries removal, caries detection and monitoring under sealants, and guided caries removal [55,117,118,127,128].…”

Dental caries remains a significant global health issue. It was highlighted by the World Health Organization’s 2022 reports that despite the efforts and scientific advancements in caries detection and management, the situation has only marginally improved over the past three decades. The persistence of this problem may be linked to outdated concepts developed almost a century ago but are still guiding dentists’ approach to caries management today. There is a need to reconsider professional strategies for preventing and managing the disease. Contemporary dentistry could benefit from embracing new concepts and technologies for caries detection and management. Dentists should explore, among others, alternative methods for caries detection such as optical-based caries detection. These tools have been established for over a decade and they align with current disease understanding and international recommendations, emphasizing early detection and minimally invasive management. This narrative review presents the current state of knowledge and recent trends in caries detection, diagnosis, monitoring, and management, offering insights into future perspectives for clinical applications and research topics.
