Summary

The aim of the study is to evaluate the efficacy of Laser Doppler flowmetry in determining the changes in the pulpal blood flow during the post-traumatic period of traumatised permanent teeth.

Detailed description

Traumatic injuries of permanent teeth in children and adolescents are very common. The conventional pulp vitality tests are inaccurate and unreliable techniques in assessing the pulp vitality during the post-traumatic period, as well as during the immature teeth examination. The aim is to evaluate the efficacy of Laser Doppler flowmetry in determining the changes in the pulpal blood flow during the post-traumatic period of traumatised permanent teeth. The study is designed as a randomized, split-mouth, controlled clinical trial. The measurement of the blood flow of the dental pulp of both, traumatised and non-traumatised teeth, will be performed, using a laser doppler flow monitor, emission wavelength 785nm±10nm, dual-channel laser Doppler monitoring option.

Type	Name	Description
DIAGNOSTIC_TEST	Measurement of pulpal blood flow of traumatised tooth	Measurement of the blood flow of the dental pulp will be performed, using a laser doppler flow monitor "mVMS-LDF2TM" (Moor Instruments Ltd Millwey Axminster Devon, UK), emission wavelength 785nm±10nm, dual-channel laser Doppler monitoring option. Two probes will be used, each consisting of one afferent and one efferent optic fiber to conduct the light to and from the tooth surface. The probe is stainless steel needle-like tube, which is 10-80 mm long and 1.5 mm in the diameter. The utilised parameter settings will be: Average power - 1.0 mV; Diameter of the probe - 1.5 mm; Frequency - 40 Hz; Monitoring time-180 seconds (sec)
