“…Modern pulse oximeters now provide an inexpensive and efficient method to measure blood oxygenation. Pulse oximetry can detect oxygen saturation levels of the pulp tissue based on spectrophotometry using a light source (wavelengths 760 and 850 nm) 65, 66, 67, 68. In one of the first studies demonstrating the utility of pulse oximetry in dentistry, Schnettler and Wallace showed that a pulse oximeter could detect pulse rate and oxygen saturation for vital teeth and not for root canal treated teeth.…”

Dentists regularly employ a variety of self‐report and sensory techniques to aid in the diagnosis and treatment of tooth‐related disease. Many of these techniques leverage principles borrowed from psychophysics, the quantitative measurement of the relationship between stimuli and evoked sensations, which falls under the larger umbrella of quantitative sensory testing (QST). However, most clinicians fail to meet the bar for what could be considered quantitative sensory testing, and instead focus on qualitative and dichotomous “yes/no” aspects of sensory experience. With our current subjective measurements for pain assessments, diagnosis and treatment of dental pain in young children and individuals (any age) with severe cognitive impairment rely extensively on third‐party observations. Consequently, the limitation of inadequate pain diagnosis can lead to poor pain management. In this review, it discusses mechanisms that underlie acute and chronic dental pain. It details the measurement of somatosensory responses and pulpal blood flow as objective measures of tooth health and pain. It proposes that bridging these varied methodologies will significantly improve diagnosis and treatment of orofacial pain and pathology. It concludes that improving the precision of sensory measurements could yield important improvements in diagnostic challenges in pulpal pathology for noncommunicative and cognitively impaired individuals.

“…A noninvasive method, Dualwavelength spectrophotometry (DWS), is also used to test pulpal blood flow. Oxygen saturation level in vascular supply of pulp is evaluated by a spectrometer that uses simultaneously released beams (760 and 850 nm) (38,39). Devital or degenerative status of pulp can be detected using this instrument (38).…”

“…Oxygen saturation level in vascular supply of pulp is evaluated by a spectrometer that uses simultaneously released beams (760 and 850 nm) (38,39). Devital or degenerative status of pulp can be detected using this instrument (38). Teeth without pulp, with fixed pulp, and teeth filled with blood rich in oxygen were tested (39) to investigate the validity of DWS and its derivative technique Pulse oximetry which is commonly used to measure oxygen saturation during the administration of intravenous anesthesia (39) performed for sedation and analgesia (40).…”

Introduction LASER (Light Amplification by Stimulated Emission of Radiation) was developed in 1960 by a scientist working for the Hughes Aircraft Corporation, Theodore Maiman, who proposed its mechanism based on the emitted beam coming from a ruby crystal (1).Lasers were tested for dental use first between 1970-1980, and laser devices such as carbon dioxide (CO 2 ) and neodymium:doped yttrium aluminum garnet (Nd:YAG) were considered suitable for hard dental tissues, while lasers were already in use for soft-tissue procedures in the middle of 1970s. Since then, many type of laser devices and applications have been used in dentistry, and new laser models and applications are still being created (2).The most common dental lasers in use today are erbium, Nd:YAG, diode, erbium, chromium doped: yttrium, scandium, gallium and garnet (Cr:YSGG), and CO 2 . Naturally, different types of lasers possess specific biological effects, are used in different procedures and, thus, are coupled with specific applicators. Nd:YAG LasersMarketed solely for dental use, these are the first true pulse lasers with a near infrared wavelength of 1064 nm (3). Primarily used for Öz 1971'de Weichman tarafından endodonti alanında ilk lazer uygulanmasının ardından, lazer teknolojisinin hızlı gelişimi ile yeni lazer cihazları ile ilgili çalışmalar hız kazanmıştır. Bu makalenin amacı, endodontide lazer uygulama alanlarıyla ilgili bilgileri güncellemek ve lazer cihazlarının avantaj ve kısıtlamaları hakkında bilgi vermektir.Since the first laser application in endodontics by Weichman in 1971, search for new laser devices is being proposed with the rapid development of laser technology. The purpose of this article is to update the information on laser application fields in endodontics and give information regarding the advantages and limitations of the laser devices.Received/Geliş Ta rihi :

ÖZETDiĢ hekimliğinde bir tedavinin baĢarısını etkileyen önemli faktörlerden biri diĢin vitalitesinin doğru bir Ģekilde belirlenmesidir. Fakat pulpanın, kalsifiye dokularla çevrili bir alanda, tamamen kapalı durumda olmasından dolayı vitalitesinin değerlendirilmesi karmaĢık bir olaydır. Bu yüzden pulpanın canlılığının değerlendirilmesinde indirekt metotlar kullanılır. Pulpa vitalite testleri pulpa kan akıĢını tespit eder, hassasiyet testlerinden daha güvenilir ölçüm metodu olarak görülür. AraĢtırmalar pulse oksimetre ve lazer doppler flowmetry gibi kan akımı ölçüm cihazlarının, pulpal vitalite değerlendirmesinde umut verici olduğunu belirtmektedir. Bu derlemenin amacı literatür bilgilerin kapsamlı olarak incelenmesi sureti ile klinisyenlere pulpa vitalite testleri hakkında güncel bilgilerin sağlanmasıdır. Anahtar Kelimeler: pulpa, vitalite, kan, akıĢ 1.PULPA VĠTALĠTE TESTLERĠPulpa hassasiyet testleri, pulpal sinirlerin uyarılmasına dayalı metotlardır. Pulpa kan akımı ile doğrudan ilgileri olmadığından, pulpanın kanlanmasıyla iliĢkili direkt bilgi vermezler. DiĢlerin vitalitesinin değerlendirilmesi sırasında, pulpal vaskülarite ile ilgili bilgi edinmek önemlidir.1 Bu nedenle geleneksel vitalite testlerini baĢlıca tanı aracı olarak kullanan diĢ hekimleri için, kök ucu kapanmamıĢ ve/veya travma geçirmiĢ diĢlerin vitalitesinin değerlendirilmesinde, pulpanın vasküler sirkülasyonu hakkında güvenilir sonuçlar verebilecek yeni test metotları geliĢtirilmiĢtir. Doku kanlanmasını ölçen yöntemlerin bir kısmı invaziv tekniklerdir. Bazılarında radyoaktif madde kullanılmakta, devamlı dinamik bir ölçüm ABSTRACTThe vitality assessment of teeth is one of the crucial diagnostic procedures in the practice of dentistry. But it is complicated by the fact that the dental pulp is enclosed within calcified tissue. Therefore, indirect methods must be used to determine pulpal vitality. Pulp vitality tests attempt to examine the presence of pulp blood flow, as this is viewed as a better measure of true health than sensibility. Investigations have stated that diagnostic devices that examine pulpal blood flow, such as the pulse oximeter and laser doppler flowmetry, show promising results for the assessment of pulp vitality. The aim of this paper is to provide the clinician with a contemporary information about the pulp vitality testing methods by detailed investigation of recent literature.
