✦ Synopsis

Background:

The purpose of this research was to evaluate the factors affecting the outcome of localized laser pulp surgery in the canine model.

Study design/materials and methods:

Pulpal exposures 2 mm and 5 mm in diameter were prepared in eight healthy teeth in each of five dogs. the total of 40 teeth were left open to infection from the oral cavity for 3 hours or 72 hours; 2-3 mm of surface pulpal tissue were then removed using a fresh diamond bur or a co2 laser [email protected] microns, at 3.5 w average power in the superpulse mode. teeth were monitored clinically and radiographically by one blinded, pre-standardized clinician for 3 months.

Results:

Chi-square test and fisher's exact test (2-tail) results associated laser treatment with significantly better clinical and radiographic outcome (p < 0.001). using regression analysis, duration of pulpal exposure to contamination by the oral environment was identified as primary determinant for treatment outcome within the laser-treated and control groups (p = 0.0018).

Conclusion:

Clinical preconditions significantly affect the outcome of pulp surgery treatments.
