Preliminary report on use of CO₂laser treatment of traumatic pulpal exposure in dogs: a clinical study

Abstract

The objective of this study was to evaluate CO2 laser surgical treatment of pulpal exposures in canine patients. 17 permanent teeth with exposures of 48h were randomly allocated to receive either (a) localized laser pulp surgery to remove all compromised soft tissues or (b) localized pulp surgery using a large round sterile bur under sterile saline irrigation. Single laser pulses were used at O.Ols pulse duration, l.Os pulse interval, a spot size of 0.004cm2 and an energy density of 276J/cm2 . Exposures were dressed with CaOH and Glass ionomer. Clinical and radiographic evaluations were performed by one blinded clinician 4, 12, 24 and 52 weeks after treatment using standard scales of O-(-1).15/17 laser-treated teeth assessed over 1 year post-treatment remained clinically and radiographically healthy.

Clinical preconditions and treatment modality: Effects on pulp surgery outcome

“…Thus the CO 2 laser is able to fulfill the prerequisites for successful localized laser pulp surgery. Preliminary in vivo studies have demonstrated good clinical outcome in minimally exposed and infected pulps after localized CO 2 laser pulp surgery [26]. However, the effect of clinical preconditions on treatment success has not been addressed at this time.…”
