Changes of PGE_2, PGI_2 and TXA_2 concentration in rat traumatic pulpitis / 中国病理生理杂志

ABSTRACT

AIM: To study the relationship between prostaglandins and acute pulpitis. METHODS: Rat traumatic pulpitis model was established by pulp exposure. The kinetic pathological changes in dental pulpal tissues and changes of PGE 2?6-Keto-PGF 1? and TXB 2 concentration in dental pulp were observed. RESULTS: After pulpal trauma, the dental pulp showed inflammatory changes and the concentrations of PGE 2?6-Keto-PGF 1? and TXB 2 were increased, which peaked at 6 hour post-trauma. CONCLUSION: Prostaglandins play a significant role in the pathogenesis of pulpitis.
