Pulse oximetry better than Pulp Sensibility Tests for Assessing Pulpal Health in Permanent Teeth
Researchers have found in a new study that Pulp Vitality Tests are better than Pulp Sensibility Tests for Assessing Pulpal Health in Permanent Teeth.
Pulp Vitality testing techniques include pulse oximetry (PO) and Laser Doppler flowmetry (LDF) out of which pulse oximetry demonstrated greater diagnostic accuracy when compared to sensibility testing.
The study has been published in the journal Evidence-Based Dentistry.
In vivo observational studies and clinical trials assessing the diagnostic accuracy of pulp vitality tests and sensibility tests in adult human teeth were screened. Exclusion criteria included non-English articles, deciduous teeth, case reports and in vitro studies.
Data extracted included basic study location, sample size, age of participants, pathology of teeth, type of teeth and the vitality (pulse oximetry or Laser Doppler flowmetry) or sensibility test (cold, hot and electric pulp testing) used. Measures of diagnostic accuracy were synthesised (sensitivity, sensibility, predictive values, and likelihood ratios). Meta-analysis was performed using a bivariate random-effects model producing summary values for sensitivity and specificity. Results were presented as a ROC curve. Risk of bias and the quality of the studies were assessed using the QUADAS-2 tool.
