Histopathologic examination compared to the traditional electric pulp testing, revealed that 24.48% of dental pulps showed complete pulp necrosis and 5.75% exhibited normal pulp tissue by histopathology. There were no significant differences in other histopathologic changes.

The frequency of a complete odontoblastic layer, vacuolar degeneration of the odontoblastic layer, pulp edema, and reticular atrophy in group 1 were significantly lower than in group 2 (P<0.05). The frequency of pulp necrosis in group 1 was significantly higher than that in group 2 (P<0.05). The dental-pulp status of histopathologic changes was analyzed. Two groups of teeth were sliced and stained with hematoxylin and eosin. According to the height of the residual periodontal membrane, all teeth were divided into two groups: group 1< (3 mm) and group 2 (3-6 mm).

Before extraction, electric pulp tests were conducted to explore the real state of the pulp. Sixty teeth were extracted from patients with advanced periodontitis. This study aimed to evaluate the dental-pulp status in patients with chronic advanced periodontitis. Fibrosis and pulpal edema were seen in 36.84% of cases.Ĭonclusion: In the presence of moderate to severe chronic periodontitis, degenerative changes such as inflammation, fibrosis, edema, calcification and necrosis were observed to variable degree. Pulp with complete necrosis was seen in 26.32% of cases. Inflammation, which was found in 47.38% of the cases, ranged from mild to severe in most sections and was always chronic. Results: Pulpal calcification (52.62%) and partial necrosis of pulp (52.62%) were found to be the most common findings. The collected teeth were stored in formalin for 24 h and were then decalcified and examined histologically after staining with hematoxylin and eosin to note the changes that occurred in pulp. Materials and Methods: Forty caries-free teeth affected with severe periodontitis were collected from patients aged between 18 and 55 years. Thus, this study aimed to evaluate the changes in pulp due to advanced periodontal disease. Nonetheless, practitioners are of the opinion that teeth having deep periodontal pockets show variable pulpal response, which may necessitate root canal treatment. Introduction: Over the past century, the dental literature has consistently reflected a controversy related to the effect of periodontal disease on the dental pulp.
