Dental pulp represents a specialized connective tissue enclosed by dentin and enamel, the most highly mineralized tissues of the body. Consequently, the direct examination as well as pathological evaluation of dental pulp is difficult. Within this anatomical context, our study aimed to evaluate the correlation between dental pulp lesions and clinical diagnosis.
Pulpectomies were performed for 54 patients with acute and chronic irreversible
pulpitides and for 5 patients (control group) with orthodontic extractions. The morphological features were semiquantitatively assessed by specific score values. The clinical and morphological correspondence was noted for 35 cases (68.62%), whereas inconsistency was recorded for 16 cases (31.38%). The results of the statistical analysis revealed the correlations between clinically and pathologically diagnosed acute/chronic
pulpitides. No significant differences were established between the score values for inflammatory infiltrate intensity,
collagen depositions, calcifications and
necrosis, and acute, respectively chronic
pulpitides. We also obtained significant differences between acute
pulpitides and inflammatory infiltrate and calcifications and between chronic
pulpitides and inflammatory infiltrate,
collagen deposition, and calcifications. On the basis of the predominant pathological aspects, namely, acute and chronic
pulpitis, we consider that the classification schemes can be simplified by adequately reducing the number of clinical entities.
