Surface temperatures of vital and nonvital teeth in humans

Influence of various polishing methods on pulp temperature

“…This volume and thus the transport of heat via perfusion are not realistic for the mandibular incisors used in this study. The surface temperature of the teeth before polishing -27.5°C -is only slightly under the published values of 28-32°C for in vivo measurements [2,6,37]. There are no in vivo measurements of intrapulpal temperature available.…”

“…Although Baysal et al [4] found that the temperature increase did not depend primarily on tooth morphology, Mizrahi et al [27] and Uzel et al [42] noted the greatest temperature increase in the mandibular incisors -hence our decision to use them in this study. To exclude the influence of [2,37]. Es wurde gefolgert, dass die Zahntemperatur hauptsächlich von passiver Konvektion [6] und weniger durch den intrapulpalen Blutstrom beeinflusst wird.…”

“…Dieses Volumen und damit die Wärme-transportfunktion über Perfusion ist für die in der vorliegenden Studie verwendeten Unterkieferfrontzähne nicht realistisch. Die Annahme, dass passive Konvektion für die Zahntemperatur wahrscheinlich wichtiger ist als Perfusion, wird [2,37]. They concluded that tooth temperature mainly depends on passive convection [6] and less on intrapulpal perfusion.…”

“…On the other hand, we noted individual increases in pulp temperature of 6.1-12.4°C. As Zach and Cohen [45] concluded that temperature auch durch die gemessene Oberflächentemperatur der Zähne von 27,5°C vor Politur gestützt, die nur leicht unterhalb der in der Literatur angegebenen In-vivo-Temperaturen von 28-32°C lag [2,6,37]. In-vivo-Messungen der intrapulpalen Temperatur liegen nicht vor.…”

Surfing the spectrum – what is on the horizon?

“…Attempts have been made to assess tooth vitality from the crown temperature but results have been inconclusive. Some studies demonstrate a higher temperature and quicker re-warm rate in vital than non-vital teeth [17][18][19] , whilst others have demonstrated no detectable difference 20 21 22 .…”
