Effect of Gingiva on laser Doppler pulpal blood flow measurements
Akpinar, KE; Er, K; Polat, S; Polat, NT (ELSEVIER SCIENCE INC, 2004)The purpose of this study was to evaluate the effect of labial and palatinal gingiva on laser Doppler pulpal blood flow measurements. Twenty upper central incisor teeth determined to be vital from 20 volunteers were included ... -
The effects of Niguldipine pretreatment on cerebral vasospasm after subarachnoid haemorrhage in rabbits
Gurelik, M; Bolat, M; Ozturk, M; Polat, S; Goksel, HM (JOHN WILEY & SONS LTD, 2004)Several different mechanisms contribute to the pathogenesis of cerebral vasospasm after subarachnoid haemorrhage. Whatever these mechanisms are, the vessel contraction is ultimately induced by an increase of free intracellular ... -
The effects of the electrical stimulation of the nasal mucosa on cortical cerebral blood flow in rabbits
Gurelik, M; Karadag, O; Polat, S; Ozum, U; Aslan, A; Gurelik, B; Goksel, HM (ELSEVIER IRELAND LTD, 2004)The cerebral vessels have sympathetic, parasympathetic, and sensory innervations. A sensory innervation of the cerebral vessels originating in the trigeminal ganglion has been described in a number of species by several ... -
The lamp effect of laser Doppler flowmetry on teeth
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 ... -
Lipiodol UF retention in dental sialography
Ozdemir, D; Polat, NT; Polat, S (BRITISH INST RADIOLOGY, 2004)Lipiodol is a lipid based contrast medium and is very useful in sialography. It gives very fine images and clearly shows the details of the gland. It is viscous and has a relatively high iodine content. However, lipiodol ... -
Penetration depth of laser Doppler flowmetry beam in teeth
Objective. The aim of this study was to determine the penetration depth of laser light in teeth for contact and noncontact probe tip. Study design. Fifty-one freshly extracted human mature maxillary and mandibular single ... -
Pulpal blood flow: effects of corticotomy and midline osteotomy in surgically assisted rapid palatal expansion
Ozturk, M; Doruk, C; Ozec, I; Polat, S; Babacan, H; Bicakci, AA (CHURCHILL LIVINGSTONE, 2003)Introduction/purpose: Surgically assisted rapid palatal expansion is used for the management of transverse maxillary deficiency in the early permanent dentition. The success depends on the maintenance of an adequate blood ... -
The sources of laser Doppler blood-flow signals recorded from vital and root canal treated teeth
Polat, S; Er, K; Akpinar, KE; Polat, NT (PERGAMON-ELSEVIER SCIENCE LTD, 2004)Objectives: The aim was to determine the strength of signals derived from the dental pulp and those from the surrounding tissues in human teeth using the laser Doppler flowmetry (LDF). Methods: Twenty-six vital teeth (13 ...
