This study was conducted on six rabbits, six rats and six human permanent teeth to evaluate histologically the effect of resin resorcinol in the periapical areas, the bacteriological aspect of the resin and the penetration of resin in the dentinal tubules. After 12 days period of observation plenty of lymphocytes and macrophages were evident along with granulomas which are suggestive of the tendency of the resin to stay longer. It was observed that the resin penetrate approximately three fourth distance inside the dentinal tubules. In the last phase the resin was found to be effective against the eight commonly found micro organisms. Though the histological results indicated that the periapical tissue would take longer time for complete repair, yet clinically the tooth functions well. Resinifying therapy is effective and economical method in root canal treatment.
本研究对6只兔子、6只大鼠和6颗人类恒牙进行,以组织学方式评估间苯二酚树脂在根尖区域的作用、树脂的细菌学情况以及树脂在牙本质小管中的渗透情况。经过12天的观察期,可见大量淋巴细胞和巨噬细胞以及肉芽肿,这表明树脂有停留较长时间的倾向。观察到树脂可渗透至牙本质小管内约四分之三的距离。在最后阶段,发现该树脂对8种常见微生物有效。尽管组织学结果表明根尖周组织完全修复需要更长时间,但临床上牙齿功能良好。根管治疗中,根管塑化治疗是一种有效且经济的方法。
