氟化

Results: The instant effects of Green Or (94.32%) and Gluma desensitizer (93.41%) were better than that of sodium fluoride glycerin (71.83%). One month later, there were no significant differences between 3 groups.

结果：极固宁脱敏组和Gluma脱敏剂的即刻有效率分别为94.32%、93.41%，显著优于氟化钠甘油脱敏组(71.83%)，而脱敏后1个月，3组间无显著性差异。

Methods A total of 147 patients with dentin hypersensitivity were randomly divided into two groups, 74 patients with 215 teeth in treatment group were treated with GLUMA desensitizer, and 73 patients with 186 teeth in control group were treated with 750 g/L sodium fluoride.

选取牙齿感觉过敏症病人147例401个牙，随机分为两组：治疗组74例215个牙，用GLUMA系统处理剂脱敏；对照组73例186个牙，用750g/L氟化钠甘油脱敏，观察两组即刻，1个月，3个月后的疗效。

Objective: To observe the clinical effects of Green Or, Gluma desensitizer and 75% sodium fluoride glycerin on the treatment of root-dentin hypersensitivity after subgingival scaling with ultrasonic instruments and discuss its desensitization mechanism.

目的：评价极固宁、Gluma脱敏剂、75%氟化钠甘油治疗超声龈下刮治所致根面牙本质敏感症的临床疗效，探讨其作用机制。

Methods: 774 dentin hypersensitivity teeth of 99 patients were randomly divided into three groups: Group A-Green Or, Group B-Gluma desensitizer, Group C-75% sodium fluoride glycerin. The results of desensitization in 3 groups were evaluated immediately and 1 month after treatment by using a visual analogue scale.

将99例龈下刮冶术所致的774颗根面牙本质过敏症患牙随机分为3组，即极固宁脱敏组、Gluma脱敏剂组和氟化钠甘油脱敏组，分别进行脱敏治疗，观察即刻、1个月疼痛的VAS值。

Results show that the best value of w is 7~10% and 5~7%, i is 0.08~0.2 A/cm^2 and 0.03~0.05 A/cm^2 respectively, during the electrolysis fluorination of pyridine and tributylamine; the addition of N-butyl mercaptan into the organic mixture can stabilize electrolysis process with its mass fraction 15~20% at best; impulse current polarization work status of low load is helpful to the electrolysis process and reduces corrosion rate of anode; electrolysis temperature is suitable at 0~20℃; electrobath can use electrolyte inner circulation structure, exterior circulation structure or blending structure.

结果表明：吡啶和N-三丁胺电解氟化的最佳值w分别为7%~10%和5%~7%，i分别为0.08~0.2A/平方公分和0.03~0.05A/平方公分；有机混合物中添加N-丁基硫醇可稳定电解过程，其质量分数最佳为15%~20%；采用低负荷的脉冲电流极化工况有利电解过程，降低阳极的腐蚀速度；电解温度0~20℃为宜；电解槽可采用电解液内循环、外循环结构，或其混合结构。

Aluminium Fluoride, molecular formula: AlF3, is mainly used to adjust the molecular ratio in aluminium electrobath, lower the smelting point of media and increase the conductivity of electrolyte. It is also used as the inhibitor in alcoholic fermen tation, the flux of vitreous enamel around the ceramics and the flux of the non-iron metal etc.

氟化铝，分子式：AlF3，白色粉状固体，主要用于调整铝电解槽电解质的分子比，降低熔点和提高电解质的导电率，还用于生产酒精时作发酵的抑止剂，陶瓷外层釉彩的助熔剂，非铁金属的熔剂等。

The influences of the original organic compound structure,content,active additive,anode current density,polarization work status,electrolyte circulation rate and temperature as well as electrobath structure during electrolysis fluorination are researched in the Center.
