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

Aim To measure pulp blood flow rates of clinically normal maxillary anterior teeth of healthy adults using ultrasound Doppler flowmetry ( UDF). Methodology A total of 359 anterior teeth from 63 patients (mean age, 29.8 years; range, 22-52 years; 26 females and 36 males) were included. The data were collected according to tooth type (three groups: central incisors, lateral incisors and canines). An MM- D- K ( Minimax, Moscow, Russia) ultrasound Doppler imaging instrument was used to measure pulp blood flow. Differences between the tooth types were analysed with one-way anova and a Bonferroni correction at the 95% confidence level. Results The mean average linear velocities during the systolic period ( Vams) of the central incisors, lateral incisors and canines were 0.58, 0.58 and 0.52 cm s−1, respectively. There were no significant differences in the mean Vams between the tooth types ( P > 0.05). Conclusions 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. [ABSTRACT FROM AUTHOR]
