Abstract

Introduction: Lasers have recently entered dentistry and the application has grown much to be used in different fields like pediatrics, periodontics, cavity preparation and Endodonthics.

Aim of the study; It is intended to find a replacement for the conventional method to be less harmful with better results.

Description and evolution; Laser has been used as an adjunct for pulpotomy treatment of tooth 85. After cavity preparation by usual methods with a bur, Diode 810 nm with the setting of 1,5w has been used for pulp fixation and the rest followed the conventional method.

The next case involved a premolar tooth with a lesion in the apex area. All steps have been as the conventional method. Finally, before obturation, Diode 810nm with the setting of 1.5w with a fiber of 200 nm was used (rotationally from apex to the coronal, 4 times, each 1 mm 2 sec).

Another case included frenectomy of a high attached frenulum of upper lip healed by Diode 810nm with the fiber of 400nm and the setting of 4w cw. The process happened much easier in a highly sterilized environment with no bleeding so the sight was crystal; hence, no sutures or bandages.

The last case is the cavity preparation of tooth 46 with Er:YAG with the setting of 250 mj, 20 Hz for enamel removal and 220 mj,15 Hz for dentin .

Discussion: Laser has some priorities over conventional method in that pain is much less with sooner healing. The results of Endodonthics showed a successful treatment due to high sterilization and tooth saving from apex surgery. In the frenectomy, the surgery occurred faster and easier with quick healing and much less pain. Carries removal proved no need to anesthesia. Moreover, fully considering conservative dentistry in this case, unlike bur preparation, the lesion areas around the tooth remain safe.
