The pulpo‐dentinal complex responds to external injuries with dentin sclerosis (DS), dead tracts (DT), or reparative dentin (RD). This investigation correlates the prevalence of these responses with age, sex, type and surface location of tooth lesions (caries, restorations, attrition, abrasion and erosion) utilizing ground sections, microradiographs and decalcified paraffin‐embedded tooth sections treated with the Pollak trichome stains (270 teeth from 113 patients). The main response to caries, restorations and erosion was DS, followed by RD and DT. DS, RD and DT occurred equally in any tooth, on any tooth surface and even beneath the same lesion. DS did not necessarily prevent RD. Root and furcation DS and RD in the floor of the pulp chamber and root canals were unrelated to particular lesions but did relate to increasing age. Root DS extended from apical to cervical area with increasing age. Beneath caries and restorations DS and RD were more prevalent in males, but DT was more prevalent in females. Pollak staining of decalcified paraffin sections for DS was approximately 80% as accurate as ground sections and micro‐radiography. In pulp studies, where the result is contrary to previous experience, the Pollak stains reveal whether DS has decreased dentin permeability.
