“…All hemodynamic values were recorded at initial, 3 min before the injection and every 3 min after anesthetic injection up to the 15 th min. Follow-up periods were determined according to Knoll-Köhler, et al 15 (1989) and Fernieini, et al 10 (2001). The monitoring procedures were standardized by keeping the cuff on the patient’s left arm, in supine position.…”

ObjectiveLocal anesthetic solutions with vasoconstrictors are not contraindicated in hypertensive patients, but due to their hemodynamic effects, local anesthetics without vasoconstrictors are mainly preferred by the clinicians. The aim of this study was to compare hemodynamic effects of three different local anesthetics without vasoconstrictors during tooth extraction in hypertensive patients.Material and MethodsSixty-five mandibular molars and premolars were extracted in 60 hypertensive patients (29 females and 31 males; mean age: 66.95 ± 10.87 years; range: 38 to 86 years old). Inferior alveolar and buccal nerve blocks were performed with 2% lidocaine hydrochloride (HCl), 2% prilocaine HCl or 3% mepivacaine HCl without vasoconstrictor. Hemodynamic parameters namely systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), saturation rate (SR), rate pressure product (RPP) and pressure rate quotient (PRQ) were investigated before and at different intervals after anesthetic injection.ResultsThe hemodynamic effects of the three agents were similar to each other, although some significance was observed for DBP, MAP, RPP and PRQ values in the lidocaine, prilocaine and mepivacaine groups.ConclusionLidocaine, prilocaine and mepivacaine solutions without vasoconstrictor can be safely used in hypertensive patients. It is advisable that dental practitioners select anesthetic solutions for hypertensive patients considering their cardiovascular effects in order to provide patient comfort and safety.

“…An increase in pulpal temperature can be affected by dentin thickness, 8,11,14 duration of light exposure and the type of light-curing device used in the curing process. 4,9,12 The pulpal blood flow rate changes in many clinical situations, such as local anaesthesia, [15][16][17] trauma to the tooth, [18][19][20][21] orthodontic movement [22][23][24] and age [18]. Many composite restorations are placed under these circumstances.…”

©Operative Dentistry, 2010, 35-3, 353-361 S-H Park • J-F Roulet • SD Heintze Clinical RelevanceBecause increase in temperature is related directly to light intensity and exposure time, curing devices with high power density (>1200 mW/cm 2 ) should only be activated for a short time (<15 seconds), even in teeth without cavity preparation. SUMMARYThis laboratory study examined the effects of curing lights with different light intensities and changing flow rate on the increase in pulpal temperature during the light curing process and the rate of the subsequent decrease in temperature after the termination of light curing.The tip of a temperature sensor was positioned on the pulpal dentinal wall of the buccal side of the maxillary premolar. Metal tubes were inserted in the palatal and buccal root of the tooth, one for water inflow and the other for water outflow. The tubes were connected to a pump to control the flow rate. The water flow rate was set to 4.2 µl/minute, 28 µl/minute or 70 µl/minute. At each flow rate, the unprepared tooth was light cured from the buccal side 1 mm from the buccal surface, using four different curing lights. The temperature data were recorded and stored on a computer every second for three minutes. The curing lights that were used were: Astralis 10 (QTH high , Ivoclar Vivadent), Bluephase 16i (LED conv , Ivoclar Vivadent) and two experimental LED-curing lights (LED exp2000 , LED exp3000 , Ivoclar Vivadent Clinical Implication: Because the increase in temperature is directly related to the light intensity and exposure time, curing devices with high power density (>1200 mW/cm 2 ) should only be activated for a short period of time (<15 seconds) even in teeth without cavity preparation. The flow rate had only a negligible effect on the temperature increase.

Laser Doppler flowmetry in endodontics: a review

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.
