Non-invasive recording of blood flow in human dental pulp.

摘要: Laser Doppler flowmetry was applied to human teeth study whether blood How in the pulp can be recorded. In sensitive, intact incisors level of output signal Ironi flowmeter clearly distinguishable from that obtained adjacent nonsensitive or pulpeetomized teeth. Heart beat synchronous oscillations, which were present recording normal teeth, absent nonvital Local injection lidocaine (20 mg/ml) with adrenaline (12.5 μg/ml) caused a pronounced and long-lasting reduction flowmetric values healthy The oscillations also reduced amplitude. Repeated recordings showed good reproducibility. Thus, changes (low may assessed tooth by tin's non-invasive method. instrument is promising tool clinical evaluation vitality following traumatic injuries.
