Background and Objective Successful non‐devitalizing treatment of localized pulpal lesions in mature teeth is not ensured using conventional endodontic techniques. The objective of this study was to evaluate CO 2 laser surgical treatment of pulpal exposures in canine patients. Study Design/Materials and Methods 17 permanent teeth with pulpal exposures of ≤48h duration received localized laser pulp surgery. Laser Parameters: pulse duration: 0.01s, pulse interval: 1.0s, spot size: 0.004cm 2 , fluence: 276J/cm 2 . Exposures were dressed with CaOH and Glass ionomer. Clinical and radiographic evaluations were performed by one blinded clinician 24 and 52 weeks after treatment. Results 15/17 laser‐treated teeth assessed over ≥1 year post‐treatment remained clinically and radiographically healthy. Conclusion These results demonstrate the feasibility of using the CO 2 laser for localized pulp surgery. Further studies must optimize laser parameters and identify the range of clinical pathologies which can be treated using this modality. Lasers Surg. Med. 21:432–437, 1997. © 1997 Wiley‐Liss, Inc.
