The sealing abilities of three therapeutic varnishes were compared with that of a conventional copal varnish in vitro under Tytin silver amalgam restorations. The therapeutic varnishes comprised two commercial fluoride varnishes and one experimental chlorhexidine-containing varnish. Leakage was traced using a basic fuchsin dye and was found to be considerable, particularly on root surfaces. The therapeutic varnishes performed as well as, and in some cases better than, the control. It is suggested that the use of preventive therapeutic varnishes in operative dentistry merits attention and further study.
在体外,将三种治疗性清漆的封闭能力与传统的柯巴清漆在钛银汞合金修复体下进行了比较。治疗性清漆包括两种市售氟化物清漆和一种含洗必泰的实验性清漆。使用碱性品红染料追踪渗漏情况,发现渗漏相当严重,尤其是在牙根表面。治疗性清漆的表现与对照相当,在某些情况下甚至优于对照。建议在牙体手术中使用预防性治疗性清漆值得关注和进一步研究。
