Clinical preconditions and treatment modality: Effects on pulp surgery outcome
Abstract
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 emitting@9.3 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.Many UC-authored scholarly publications are freely available on this site because of the UC's open access policies. Let us know how this access is important for you.
