The aim of this study was to examine the effectiveness of antifungal gels incorporated into a tissue conditioner which inhibits the growth of Candida albicans in vitro.
The release of drugs from relining materials has been demonstrated earlier. However, the incorporation of antifungal agents in gel form has not yet been studied.
Visco-gel(®) tissue conditioner was prepared with chlorhexidine digluconate and miconazole in gel form in a concentration of 5, 10, 15, 20 and 25% by volume. Sample discs were prepared and placed on Sabouraud Dextrose Agar (SDA) plates which had been previously inoculated with C. albicans, and incubated aerobically at 37 °C. To investigate antifungal activity over time, Visco-gel discs containing 20%v/v miconazole were prepared and immersed in water for different time periods before being placed on SDA plates inoculated with C. albicans.
Chlorhexidine digluconate gel added to tissue conditioner had no inhibition effect on the growth of C. albicans. Incorporation of miconazole gave a dose-related inhibitory effect on candidal growth. Immersion of the discs in water showed an inverse relationship between time of immersion and degree of inhibition.
Miconazole added in gel form to Visco-gel(®) had an inhibitory effect on the growth of C. albicans in vitro.
本研究旨在检验一种含有抗真菌剂的义齿基托材料的凝胶体,以抑制体外白色念珠菌生长的有效性。
先前已有研究表明药物可从衬垫材料中释放。但是,凝胶形式的抗真菌剂的加入尚未被研究。
用洗必泰葡萄糖酸和咪康唑以体积浓度 5%、10%、15%、20%和 25%的比例制成了含凝胶的 Visco-gel(®)组织调节剂。制备了样品盘,并将其放置在预先接种了白色念珠菌的沙氏葡萄糖琼脂(SDA)平板上,在 37°C 下有氧孵育。为了研究随时间的抗真菌活性,制备了含有 20%v/v 咪康唑的 Visco-gel 圆盘,并在将其放置在接种了白色念珠菌的 SDA 平板上之前,将其浸入水中不同时间。
添加到组织调节剂中的洗必泰葡萄糖酸凝胶对白色念珠菌的生长没有抑制作用。咪康唑的加入对白色念珠菌的生长具有剂量相关的抑制作用。圆盘的浸泡时间与抑制程度呈反比关系。
以凝胶形式添加到 Visco-gel(®)中的咪康唑对体外白色念珠菌的生长具有抑制作用。
