✦ Synopsis

Background and Objective: A previous study [Moritz et al., Z

Stomatol 1996; 93:451-454] had shown that favourable results in direct pulp capping could be achieved using a continuous wave CO 2 laser in addition to the conventional calcium hydroxide dressing technique. In this study, these results are compared to those achieved using a CO 2 laser working in superpulsed mode. Study Design/Materials and Methods: A total of 260 direct pulp capping procedures were carried out; 130 were performed with a superpulsed CO 2 laser, followed by a calcium hydroxide dressing, and 130 conventionally by applying only a calcium hydroxide preparation. Recall examinations were performed after 1 week and monthly for 18 months after treatment. A final examination was carried out 2 years after treatment. Thermal tests were used for vitality assessments and laser Doppler flowmetry for direct measurement of pulpal blood flow. Results: In the group of pulps treated with the superpulsed CO 2 laser, the last recall examination at 2 years revealed that 93% of the teeth had remained vital. In the control group, the success rate was considerably lower (66.6%). Exposure site sizes and average patient age were nearly identical in both groups.

Conclusion:

The CO 2 laser seems to be a valuable aid in direct pulp capping; the efficiency of laser treatment can be increased by using a pulsed CO 2 laser.
