“…During follow-up examinations the traumatized tooth can be unresponsive to traditional vitality testing during the first 6 months; however, LDF indicated that revascularization had occurred much sooner. Until recently, CO 2 ice has been the most effective method for sensitivity testing in trauma cases but LDF is able to give the assurance that we could defer invasive care during critical time period when the root canal therapy might have been initiated for the patient [63]. The information obtained by LDF is of additional importance for the treatment planning.…”

This chapter presents the most important features of laser Doppler (LD) techniques: LD flowmetry (LDF) and LD imaging (LDI), together with examples of their clinical applications in dentistry. LDF gives a constant estimation of blood flow at a specified point, whereas LDI gives a 'snapshot' of perfusion at a given point. These methods are non-invasive laser-based techniques for monitoring gingival and pulpal blood flow and could be used as a diagnostic tool. In paediatric dentistry and odontology, LDF proved to be an atraumatic real-time method used for determining the tooth vitality by monitoring the pulp microcirculation in traumatized teeth, fractured teeth and teeth undergoing different conservative treatments (e.g. bleaching, dental preparation for prosthetic restorations, etc.). In periodontology, recent studies showed the ability of LDF to evaluate the health of gingival tissue in different types of periodontal diseases. By using LDF, it is also possible to evaluate the outcome after different periodontal treatments. The laser Doppler line scanning can be used for recording the gingival healing process after a surgical procedure in the anterior area of the oral cavity.

Despite the many journal articles and reviews that have been published regarding the treatment of trauma to teeth, the endodontic management of these injuries is often still not fully understood. The purpose of this review is to establish clear and up-todate guidelines for practitioners who are faced with treating dental injuries on a day-to-day basis, based on an assessment of current available scientific information relating to the endodontic management of these injuries. Treatment is discussed under the headings: infractions, uncomplicated crown fractures, complicated crown fractures, crown-root fractures, root fractures, luxation injuries, avulsion, root resorption, pulp canal obliteration and open-apex teeth. Emphasis is placed on the treatment of traumatized immature teeth where maintenance of pulp blood supply is important to encourage continued development of the root system. Only the treatment of traumatized permanent anterior teeth is reviewed. Information contained in this article is based on a review of the literature on dental trauma which involved a MEDLINE search using the key words "dental trauma" and the individual topics listed above. The guidelines produced by the International Association of Dental Traumatology, the American Academy of Pediatric Dentistry and the American Association of Endodontists were also reviewed and the recommendations contained in this paper are in concert with the major recommendations of these bodies.

“…If endodontic treatment is initiated whilst blood vessels are attempting to regrow through the apical foramen, the pulp healing is arrested and there is no further development of the root in immature teeth. LDF is an accurate and objective technique for assessment of pulpal vitality in these teeth , Andreasen 1989, Heithersay & Hirsch 1993, Andreasen & Andreasen 1994, Ebihara et al 1996, Mesaros & Trope 1997, Evans et al 1999, Lee et al 2001, Roeykens et al 2002, Strobl et al 2003,b, 2005,b,c,d, Emshoff et al 2008, Winzap-Kälin et al 2005.…”

Vascular supply is the most accurate marker of pulp vitality. Tests for assessing vascular supply that rely on the passage of light through a tooth have been considered as possible methods for detecting pulp vitality. Laser Doppler flowmetry (LDF), which is a noninvasive, objective, painless, semi-quantitative method, has been shown to be reliable for measuring pulpal blood flow. The relevant literature on LDF in the context of endodontics up to March 2008 was reviewed using PubMed and MEDLINE database searches. This search identified papers published between June 1983 and March 2008. Laser light is transmitted to the pulp by means of a fibre optic probe. Scattered light from moving red blood cells will be frequency-shifted whilst that from the static tissue remains unshifted. The reflected light, composed of Doppler-shifted and unshifted light, is returned by afferent fibres and a signal is produced. This technique has been successfully employed for estimating pulpal vitality in adults and children, differential diagnosis of apical radiolucencies (on the basis of pulp vitality), examining the reactions to pharmacological agents or electrical and thermal stimulation, and monitoring of pulpal responses to orthodontic procedures and traumatic injuries. Assessments may be highly susceptible to environmental and technique-related factors. Nonpulpal signals, principally from periodontal blood flow, may contaminate the signal. Because this test produces no noxious stimuli, apprehensive or distressed patients accept it more readily than current methods of pulp vitality assessment. A review of the literature and a discussion of the application of this system in endodontics are presented.
