The lack of pulpal pathosis in rice rats with the periodontal syndrome.
The purpose of this study was to determine in the rice rat model whether a relationship exists between the severity of periodontal disease and the presence of severity of pulpal lesions. The results indicated that, even in the presence of severe loss of alveolar bone, extending close to the root apices, there were no detectable changes in the pulpal tissues as compared to the pulps of teeth in which there was no loss of alveolar bone. The scarcity of accessory pulp canals in the rice rat may be related to our findings.
