Abstract
The integration of laser technology into restorative dentistry has expanded significantly, offering innovative and minimally invasive approaches for the management of hard dental tissues. Laser systems are increasingly utilized for cavity preparation, selective ablation of caries, and surface modification to enhance restorative material adhesion. Laser irradiation can effectively remove the smear layer, create microretentive surface topographies, and induce physicochemical alterations in dental substrates, thereby influencing bonding performance and potentially reducing the need for conventional mechanical instrumentation.
Beyond hard tissue applications, lasers have also demonstrated clinical value in the management of dentin hypersensitivity through mechanisms such as dentinal tubule occlusion, protein coagulation, and modulation of neural responses. Furthermore, in aesthetic dentistry, laser-assisted tooth bleaching has gained attention for its ability to accelerate the activation of bleaching agents, shorten chair-side treatment time, and improve patient comfort.
In summary, laser technologies in restorative dentistry offer more accurate tissue management and enhanced patient comfort, which supports minimally invasive concepts. Lasers can be a useful complement to conventional methods when utilized with the right indications and parameters. However, careful case selection, operator expertise, and adherence to evidence-based protocols are necessary for long-term therapeutic success.
