The effect of food simulants upon the enamel-composite bond strength of two orthodontic adhesive composites was studied. Thirty extracted premolars were used in each experimental group. Orthodontic brackets were bonded with either Transbond (3M Unitek) or Right-On (TP orthodontics) and were then exposed to either distilled water (control), 8 per cent ethanol (aqueous food), 50 per cent ethanol (alcoholic food), buffered lactic acid pH4 (acidic food), or corn oil (fatty food) for 12 weeks. Bond strength and Adhesive Remnant Index was recorded. It was found that 50 per cent ethanol had a significant effect upon the bond strength of both Transbond and Right-On. Right-On was affected to a greater extent. The clinical significance of this finding is that alcoholic mouth rinses, and alcohol-containing foods and drinks may be a causative factor in bond failure. However, the use of an alcoholic mouthrinse late in treatment may aid bracket removal. This potential use requires more research. Refereed Scientific Paper
研究了食品模拟物对两种正畸粘结复合材料与牙釉质粘结强度的影响。每个实验组使用30颗拔除的前磨牙。用Transbond（3M Unitek）或Right-On（TP正畸）粘结正畸托槽，然后将其置于蒸馏水（对照）、8%乙醇（水性食品）、50%乙醇（含酒精食品）、pH4的缓冲乳酸（酸性食品）或玉米油（脂肪性食品）中12周。记录粘结强度和粘结剂残留指数。发现50%乙醇对Transbond和Right-On的粘结强度均有显著影响。Right-On受到的影响更大。这一发现的临床意义在于，含酒精的漱口水以及含酒精的食品和饮料可能是粘结失败的一个致病因素。然而，在治疗后期使用含酒精的漱口水可能有助于托槽去除。这种潜在用途需要更多的研究。经同行评审的科学论文
