Abstract

Wistar rats given a single intraperitoneal injection of 75 mg cyclophosphamide revealed dental anomalies in the form of shortening or lengthening of incisors, and development of supernumerary teeth. Rats given additionally 5 mg/kg b. w. of a nitrosomethylurea solution over a period of four months showed the same dental anomalies, but with relatively shorter latency times. In a supplementary investigation examining the effects of benzo(a)pyrene and nitrosomethylurea applied locally to the organon dentale, neoplastic lesions and dental dysplasia were seen.

环磷酰胺、亚硝基甲基脲和苯并(a)芘对大鼠门牙的影响
单次腹腔注射环磷酰胺75 mg后,Wistar大鼠出现门牙缩短或延长、多牙发育等牙齿畸形。在4个月的时间里,给药5 mg/kg体重的亚甲基脲溶液的大鼠也出现了同样的牙齿异常,但潜伏期相对较短。在一项补充调查中,检查了苯并(a)芘和亚硝基somethylurea局部应用于齿状器官的影响,可以看到肿瘤病变和牙齿发育不良。
