Diagnostic accuracy of Transmitted-light plethysmography for the assessment of pulpal circulation in traumatized young permanent incisors.

ABSTRACT: Transmitted light plethysmography (TLP) is a noninvasive, objective optical method used to assess dental pulp circulation and evaluate pulp vitality. This study aimed to develop a quantitative diagnostic approach for TLP and assess its accuracy through cross-correlation analysis of plethysmographic signals obtained from both the tooth and the finger. A total of 131 maxillary incisors from 97 pediatric patients (aged 6-17 years) were categorized into three groups: nontraumatized teeth, traumatized vital teeth, and traumatized nonvital teeth. Standard diagnostic procedures, including assessments for discoloration, percussion sensitivity, periapical translucency, and electric pulp testing (EPT), were performed alongside TLP evaluation, 3 to 18 months following dental trauma.
