    摘要: 常喝酸性軟性飲料的矯正患者會造成牙齒表面牙釉質的腐蝕、矯正器的腐蝕、牙齒周圍黏著劑和樹脂變色、蛀牙率增高、肥胖，亦造成矯正器黏結的強度下降；但酸性軟性飲料對矯正線的影響卻鮮少被討論。因此，本研究目的將研究軟性飲料對兩種含鎳的矯正線的影響。實驗分成0.016英吋之不鏽鋼圓線、0.016英吋鎳鈦圓線和0.016英吋鈦鉬圓線三組進行討論，這三組再次分為四個浸泡小組，分別為可口可樂（Coca-Cola®）、雪碧（Sprite®）、紅茶（麥香紅茶®）、以及控制組人工唾液（欣露®人工唾液）。每天直接從冰箱拿出已冷藏之軟性飲料浸泡兩次，一次三十分鐘，共浸泡四週。後續從拉伸測試以及電子顯微鏡觀察這些軟性飲料對矯正線的影響。
    Orthodontic patients who love acidic soft drinks will increase the opportunity of enamel erosion, corrosion of orthodontic appliance, discoloration of resin and bonding agent, dental caries, obesity, decrease of orthodontic brackets bonding strength and so no. However, whether these acidic soft drinks would affect orthodontic wires were seldom discussed. The purpose of this study was to investigate the effect of acidic soft drinks on orthodontic wires. The orthodontic wires are divided into 3 groups: 0.016-inch stainless steel round wire, 0.016-inch NiTi round wire, and 0.016-inch TMA round wire. And each wire group subdivided by four subgroups: Coca-Cola, Sprite, black tea, and artificial saliva (control). The orthodontic wires were rinsed with cold soft drinks 30 minutes twice a day for 28 days. The orthodontic wires then were stretched with ＂universal testing machine＂ for tensile test. A scanning electron microscopes and metalloscope were used to determine the amount of corrosion of the wires. The results indicated that Coca-Cola and Sprite subgroups had significant corrosion effect over orthodontic wires than black tea. All 3 types of wires showed surface corrosion, especially TMA wires. NiTi wires had less corrosion than stainless steel wires. The orthodontic wires showed no significant difference between groups in tensile test, and also the tensile curve.
