CO2 laser application in stomatology

The CO2 laser has found great acceptance in the stomatologic field of dentistry. This article gives an overview of the most important bene fits. The absorption of the laser light produces photothermal effects such as coagulation, vaporization and photoablation. The main indications in stomatology are pain alleviation and prevention of recurences in aphthae and cold sores (minor aphthae, herpes simplex), ablation of benign and irritant tissue excess (stimulus fibroma), lip and tongue band correction and soft tissue hemostasis. One great advantage is the minimal bleeding in the surgical field, which allows for optimal visibility. In addition, the CO2 laser offers high patient comfort since no primary wound closure with sutures are required. However, in suspect of malignancy a sharp excision with a scalpel is still preferred due to possible compromisation of the histopathologic evaluation.
