“…Considerable shunting occurs in the apical half of the pulp. 48 When the intrapulpal pressure rises during inflammation, these shunt vessels may open up to reduce the intrapulpal pressure so that the normal blood flow is maintained. 49 …”

The dental pulp is a unique tissue and its importance in the long-term prognosis of the tooth is often ignored by clinicians. It is unique in that it resides in a rigid chamber which provides strong mechanical support and protection from the microbial rich oral environment. If this rigid shell loses its structural integrity, the pulp is under the threat of the adverse stimuli from the mouth, such as caries, cracks, fractures and open restoration margins, all of which provide pathways for micro-organisms and their toxins to enter the pulp. The pulp initially responds to irritation by becoming inflamed and, if left untreated, this will progress to pulp necrosis and infection. The inflammation will also spread to the surrounding alveolar bone and cause periapical pathosis. The magnitude of pulp-related problems should not be underestimated since their most serious consequence is oral sepsis, which can be life threatening, and hence correct diagnosis and management are essential. Clinicians must have a thorough understanding of the physiological and pathological features of the dental pulp as well as the biological consequences of treatment interventions.

“…47 Numerous shunt vessels have also been observed in the dental pulp, although their function is less well understood. 39,48 These vessels can be arterio-venous anastomoses, venous-venous anastomoses or U-turn loops. They provide a direct communication between arterioles and venules, hence bypassing the capillary bed.…”

“…Several experimental methods have been used to evaluate pulpal circulation. These include invasive techniques such as radioisotope clearance (4) and H 2 gas desaturation (5) and noninvasive methods such as laser Doppler flowmetry (6)(7)(8)(9)(10)(11), pulse oximetry (3,(12)(13)(14), dual wavelength spectrophotometry (15), photoplethysmography (16), and measurement of surface temperature (17)(18)(19)(20).…”

“…As studied by vital microscopy 14) , a clearance technique 15,16) , or laser Doppler flowmetry 17) , PBF has been shown to be increased by heating and decreased by cooling of the tooth in anesthetized animals. Kim et al 18) , measured the changes in PBF (in ㎖/min/100g pulpal tissue) in dogs in response to an incremental increase in tooth surface temperature using the Xenon 133 washout method. PBF increased slightly and gradually as the tooth surface temperature was raised from 35 to 40℃.…”
