Measurement of pulp blood flow rates in maxillary anterior teeth using ultrasound Doppler flowmetry

Abstract

Within the limitations of this study, the pulp blood velocities of clinically normal, maxillary anterior teeth of healthy adults were between 0.5 and 0.6 cm s(-1) . There were no significant differences in mean blood flow rates between maxillary central incisors, lateral incisors and canines.

Effects of age, sex, and blood pressure on the blood flow velocity in dental pulp measured by Doppler ultrasound technique

“…Tooth type had no significant effect on the PBFV, and this was in agreement with a previous study that analyzed the mean PBFV of 359 maxillary anterior teeth . The mean PBFV was 0.508 cm/s in this study, which was roughly comparable to the results of the previous study (0.56 cm/s).…”

“…Changes in the PBFV can be identified after infiltration with an anesthetic agent containing epinephrine . The mean PBFV of normal maxillary anterior teeth was successfully measured and found to be approximately 0.56 cm/s regardless of tooth type . These results imply that Doppler ultrasound can be an effective clinical diagnostic tool for the dental pulp.…”

“…The unit of analysis was the tooth, with the subject being the cluster. The PBFV was a dependent variable, and the Vam from each Doppler spectrum was used for the analysis as described in a previous study . Age, sex, systolic BP, and tooth type were examined for significance in a generalized linear model analysis.…”

The diagnostic accuracy of laser Doppler flowmetry in assessing pulp blood flow in permanent teeth: A systematic review

“…Thus, vitality testing involves assessing the pulp's blood supply offering an objective approach to assessing pulp blood flow that is not reliant on the patient's understanding and response to stimuli . Vitality tests include laser Doppler flowmetry (LDF), pulse oximetry and more recently the use of ultrasound Doppler flowmetry …”

“…5 Vitality tests include laser Doppler flowmetry (LDF), pulse oximetry and more recently the use of ultrasound Doppler flowmetry. 6,7 LDF was first described in the dental literature in 1986. 8 The primary technique utilized a light beam originating from a helium-neon (He-Ne) laser emitting with a wavelength of 632.8 nm.…”
