Laser in pediatric dentistry

Abstract

Introduction: Laser in pediatric dentistry has become an important tool in photobiomodulation, photodynamic therapy, and soft tissue surgeries, providing benefits through selective and precise interaction with tissues. Results: When used in soft tissue surgeries, hemostasis can be achieved without the need for sutures, with faster healing and less postoperative discomfort. Another benefit is related to the minimal need for local anesthesia, in addition to reduced chair time. Lasers demonstrate bactericidal properties in tissues, preventing infections and the prescription of antibiotics postoperatively. When used in photobiomodulation, they provide pain and inflammation relief. Furthermore, lasers can remove carious lesions with minimal impact on surrounding dental structures, without the noise and vibration of conventional dental handpieces. In hard tissues, Nd:YAG and erbium lasers have shown an analgesic effect, eliminating the use of local anesthesia during dental preparations. Discussion: Some disadvantages in the use of lasers in pediatric dentistry are related to the need to acquire different devices due to their various wavelengths, as well as the high cost of some equipment. However, the benefits of this technology outweigh these limitations. In addition, the use of lasers requires further training and education for the different clinical applications and types of lasers. Conclusion: The application of laser in pediatric dentistry offers an effective and safe approach, improving both the child patient’s experience and clinical outcomes.
