Surgical lasers and hard dental tissue

Area of Science:

• Dental materials science
• Biomedical engineering
• Laser physics

Background:

• Conventional dental cutting methods pose challenges in selectively removing carious tissue while preserving healthy tooth structure.
• Patient-driven demand for less invasive treatments has spurred the development of alternative dental instrumentation.
• Current laser technologies have demonstrated beneficial effects in dental hard tissue procedures.

Purpose of the Study:

• To explore the interaction of laser energy with dental hard tissues and bone.
• To review the integration of current laser wavelengths into restorative and surgical dentistry.
• To evaluate the potential of ultra-short pulsed lasers for improved hard tissue ablation.

Main Methods:

• Literature review of existing studies on laser applications in dentistry.
• Analysis of laser-tissue interactions, focusing on dental hard tissues and bone.
• Exploration of current and emerging laser technologies, including ultra-short pulsed lasers.

Main Results:

• Current laser machines offer beneficial effects in dental procedures.
• Ultra-short pulsed lasers (nano- and femtosecond) show potential for efficient hard tissue ablation.
• These advanced lasers may reduce the risk of collateral thermal damage compared to conventional methods.

Conclusions:

• Laser technology is advancing for dental hard tissue applications.
• Ultra-short pulsed lasers represent a promising frontier for minimally invasive restorative and surgical dentistry.
• Further development of stable and commercially viable ultra-short pulsed lasers is warranted.
