[Effects of the CO2 laser on mandibular bone. Preliminary study]. / Effets du laser CO2 sur l'os mandibulaire. Etude préliminaire.

A study of the effects of the CO2 laser on bone was undertaken using human mandibles obtained from cadavers. Different series of shots were used, varying the power and duration of the shots, as well as the latent period between two impacts with intermittent shooting. For a given impact duration, the depth of penetration increased in proportion to power up to 25 watts. Beyond, penetration was less deep but more extensive. For a given intensity, the duration of the shot did not result in any variation in penetration. These findings and their possible clinical implications are discussed.
