Pulse Oximetry and Laser Doppler Flowmetry in Young Permanent Teeth

Objective: Current traditional methods of assessing pulp vitality are of limited use with children. Pulse Oximetry (PO) and Laser Doppler Flowmetry (LDF) are non-invasive methods to measure blood flow, which have been recently introduced as a new method to diagnose pulp vitality in human teeth.

The aim of this study was to evaluate the efficacy of PO and LDF in immature, young permanent teeth which have different root formation level (RFL).

Method: Recordings of PO and LDF and the responses of electrical pulp tests (EPT) were taken from 138 healthy maxillary permanent incisors (45 couple of central-24 couple of lateral) which have different RFL, in totally 45 children (between 8-12 years-old, mean: 9.7±1.1).

Results: The LDF values demonstrated a negative correlation between children’s age (r= -0.60, p=0.0001) and a positive correlation between root apex distance (millimeter) of teeth (r= 0.85, p=0.0001) although PO didn’t demonstrated any significant correlation. The calculated selectivity of PO and EPT was 0.97 and 0.95 respectively.

Conclusions: It was determined that the pulpal blood flow of young permanent teeth had decreased with age and the progression of root formation stage. LDF was found to be a more reliable and effective method in monitoring of pulpal blood flow and vitality of immature young permanent teeth. However, the improvement of LDF with further researches is indicated.
