Laser Doppler Flowmetry for monitoring traumatized teeth

Dental Traumatology, 2001
Abstract – Laser Doppler Flowmetry (LDF) has been shown to be valuable in monitoring revascularization of immature incisors following severe dental trauma. Several investigators have demonstrated the ability of LDF to record blood flow signals from vital tooth pulps.

Waveform analysis applied to laser doppler flowmetry

Microsurgery, 1986
AbstractLaser Doppler flowmetry (LDF) has been found useful in monitoring free flaps. In the present study, waveform analysis has been applied to the LDF waveform. Waveform changes were investigated in the microcirculation during varying degrees of arterial or venous occlusion in the saphenous island and flap of the dog and the human digit.

Principles of Laser-Doppler Flowmetry

1990
Light scattering has long been used to probe properties of bulk matter. In transparent media such as air or clear water, measurements can be analyzed easily and remote sensing can be done over great distances. The basic principles relating the intensity of scattered light to underlying molecular structure were established by Lord Rayleigh in his ...

Vaginal Laser Doppler Flowmetry Pre- and Posthysterectomy

Journal of Sex & Marital Therapy, 2004
The objective of this study was to demonstrate the applicability of laser doppler flowmetry to pre- and posthysterectomy vaginal blood flow assessment. We used laser Doppler flowmetry to measure pre-and postoperational vaginal blood flow in 8 premenopausal women undergoing benign hysterectomies; we also measured serum E2, FSH, FT and administered a ...

The lamp effect of laser Doppler flowmetry on teeth

Journal of Oral Rehabilitation, 2005
summary  The aim of this study is to analyse the intra and extracoronal scattering of laser light. Twelve vital teeth from 12 volunteer individuals (aged 22–29 years) were used. The camera removing the charge coupled device's infrared cut filter was used for imaging the laser Doppler flowmetry light during pulpal blood flow measurement.

The anatomy of the human promontory for laser Doppler flowmetry

European Archives of Oto-Rhino-Laryngology, 1997
Studies of the dynamic characteristics of cochlear blood flow (CBF) utilizing laser Doppler flowmetry (LDF) in laboratory animals have provided a new approach to the understanding of control mechanisms of CBF and the role of the CBF in cochlear disorders. However, few studies exist indicating that LDF of human CBF may be possible. Since bone thickness,

The use of laser Doppler flowmetry in paediatric dentistry

European Archives of Paediatric Dentistry, 2011
An early determination of pulpal vitality is crucial with respect to a correct differential diagnosis of revascularisation or necrosis and its treatment.Sensibility tests (cold, heat, electrical pulp test) in combination with radiographs are commonly promoted. However these tests are arbitrary, based on sensations and therefore not always reliable.

Quantitative testing of sympathetic function with laser doppler flowmetry

Journal of Clinical Monitoring, 1992
The objective of this study was to develop an indirect technique for evaluating dynamic changes in sympathetic function in humans.We used laser Doppler to monitor sympathetic mediated vasoconstrictive responses (VRs) produced by 3 different provocative stimuli: 4-second inspiratory gasp (IG), ice-water immersion (Ice), and a spring-loaded pin prick ...

Laser doppler flowmetry in neurosurgery

1991
Laser Doppler Flowmeter (LDF) is a new, reliable and simple method to monitor regional Cerebral Blood Flow (RCBF). Our group began to perform intraoperative LD recordings in 1986. Recently, the advent of new special probes and the use of computer techniques, allowed two important improvements: an easy and safe postoperative LDF monitoring in Intensive ...
