Evaluation of the novel anti-inflammatory agent tetrandrine as a pulpotomy medicament in a canine model.

Tetrandrine, a bisbenzylisoquinoline alkaloid with unique broad-spectrum anti-inflammatory properties, was evaluated as a pulpotomy medicament in a canine model. Histological sections were evaluated after three days (acute inflammation) and six weeks (chronic inflammation) by two criteria: 1) intensity and degree of inflammation, and 2) extent of pulp involvement. The results of the three-day dressings revealed significant neutrophil infiltration in only 30% of teeth treated with tetrandrine, compared with 81%, 84%, and 100% of teeth treated with Ledermix, (Lederle Pharmaceuticals, Wolfrathausen, Germany), formocresol (Creighton Pharmaceuticals, Sydney, Australia) and saline (controls) respectively (P < 0.01). After six weeks, there was significant lymphocyte infiltration in only 30% of teeth treated with tetrandrine, compared with 66%, 90%, and 100% on teeth treated with Ledermix, formocresol, and saline controls respectively. (P < 0.01). In both three-day and six-week specimens in tetrandrine-treated teeth the extent of inflammation was limited to less than one-third of the coronal section of the pulp, whereas teeth treated with Ledermix or formocresol showed cellular infiltration extending to greater than two-thirds of the pulp (P < 0.01). Comparative studies with berbamine, a natural analog of tetrandrine, showed that it was less potent than tetrandrine, but significantly better than Ledermix and formocresol on both acute and chronic pulp inflammation (P < 0.05 and P < 0.01 respectively). These results suggest that tetrandrine may have value as a pulpotomy medicament.[1]
