Outcomes of dental fracture injury as related to laser Doppler flow measurements of pulpal blood-flow level Rüdiger E et al. - A logistic regression analysis was used to compute the odds ratios for the outcome features for incisor non-injury controls vs two outcome groups: type II and type III. PBF measurements that were significantly associated with more severe outcome were PBF levels of perfusion units (PU) (106.70 odds ratio). Significant increase in the risk of a PBF level of < = 6 PU occurred with a type III outcome (32.49 odds ratio). [more...]
