Pulpal Hyperemia—A Correlation of Clinical and Histologic Data from 706 Teeth

A Clinical and Histological Report of a Tooth with an Open Apex Treated with Regenerative Endodontics Using Platelet-rich Plasma

“…Examination of the soft tissue removed from the canal showed the absence of any signs of severe pathosis. However, there is little or no correlation between the histologic findings of pulpal pathosis and clinical symptoms (34). The presence of a few inflammatory cells in the periphery of the specimens and scattered small calcific materials could be because of the reaction of the pulp-like tissue to the external irritants.…”

Identify and Define All Diagnostic Terms for Pulpal Health and Disease States

“…Clinically, however, only a limited number of pulpal conditions can be described on the basis of examination findings for a patient. Several studies have shown that there is little or no correlation between clinical diagnostic findings and the histopathologic state of the pulp (54)(55)(56)(57)(58)(59)(60)(61)(62)(63). Because histopathologic diagnosis is not truly available to the endodontic clinician and because diagnosis is needed to perform clinical endodontic treatment, then the various disease states of the pulp must be described by using a clinical classification scheme.…”

“…Occasionally, the necrotic pulp might respond to heat application (49). Of all the histopathologic pulpal states, necrosis is the one that is most reliably predicted from clinical testing (54,56), with high correlations between negative pulp tests and necrosis of the pulp, although this finding is not universally supported (58). Partial pulp necrosis (necrobiosis) (65) is very difficult to diagnose especially in multi-rooted teeth, which might have different pulp states in different roots within the same tooth.…”

Pulse Oximetry and Electric Pulp Test in Intact Teeth and Teeth with Hyperaemia Pulpae

“…Some studies have shown that pulp conditions, clinically defi ned as hyperemia, histologically very rarely correspond to this diagnosis [7]. Therefore, it is spoken about pulp hypersensitivity [4,6,13,14].…”
