Caries removal and cavity preparation using Er: Yag laser in dental practice: literature review

Caries removal and cavity preparation are associated with restorative treatment in carious teeth. Cutting dental hard tissue is challenging to remove the carious tissue and maintain the healthy tissue to support the restoration. In recent decades, the laser has been widely used in dental practices and played a significant role in non-invasive treatment approaches. The laser with the highest efficiency for hard tissue and useful for dental caries is the Er:YAG laser, which is approved by the Food and Drug Administration (FDA). This literature review aims to list the benefits of employing Er:YAG lasers in dentistry practices for cavity preparation and caries eradication. More healthy tissue can be preserved with more precision, a clean surface, and a smear-layer-free surface thanks to use the Er:YAG laser to remove cavities. Using Er:YAG laser in dental practice can reduce the risk of infection because it provides a surface decontamination effect and generates less aerosol. Patients will also feel more comfortable and painless during the treatment. Dental practitioners and patients have significantly benefited from cavity preparation and using the Er:YAG laser to remove dental cavities.
