Background: This human study was carried out to evaluate the possible effects of severe chronic periodontal disease on the different aspect of dental pulp structure. Materials and Methods: A total of 20 permanent teeth with a hopeless prognosis due to severe chronic periodontitis were extracted from systemically healthy adults, with a pocket probing depth of ≥8 mm and a mobility of grade 3. After extraction, the apical 2-3 mm of the roots were immediately sectioned with a fissure bur. Results: Inflammation was usual finding in the samples, however, only 15% of the teeth showed no inflammation. Pulpal necrosis (partial or complete) was seen in different sections, and it was observed that 50% sections had no necrosis. Partial necrosis was a common finding seen when compared to complete necrosis (6.7%). About 60% of samples showed edematous pulp. Only 6.7% of samples showed absence of fibrosis. Pulp with moderate fibrosis was seen commonly seen in many sections. A majority of teeth (70%) also displayed a loss of odontoblastic integrity. In only 25% of samples, pulp stones were detected. Conclusion: Our results revealed that severe chronic periodontitis can affect dental pulp. The cumulative effect of the periodontal disease, as indicated by the factors of calcifications, apposition of calcified tissue, resorption or inflammation from the root caries or from the involved lateral canals, is damaged pulp tissue, but total disintegration is a certainty only when all main apical foramina are involved by bacterial plaque. Proper evaluation and treatment of periodontal-endodontic involvement is recommended.
