Low-level lasers (LLL) are used in the stomatology and oral surgery field of dentistry. Due to the biostimulation or biomodulation and photodynamic effect, the healing process of soft-tissue and bone wounds can be accelerated. The indication in oral surgery is to achieve a faster bone healing after tooth extraction, but also to improve the osseointegration in implants. The advantage in stomatology is pain alleviation and improved healing in aphthae and cold sores as well as symptom relief in mucositis. Due to the use free of side effects and low time effort, the LLL offers high patients' comfort.
