This study examined the effectiveness of suctioning devices in reducing oral fluoride retention after professional 4-minute applications of a 1.23% fluoride gel. The value of patient expectoration was also evaluated in the child subjects. The suction devices were statistically significant adjuncts in reducing oral-retained fluoride in all cases; however, the oral-retained fluoride doses after the suctioning procedures were still distinct in both adults (10.3 +/- 2.3 mg) and children (7.7 +/- 1.0 mg). These amounts of oral-retained fluoride would result in substantial elevations in body fluid fluoride concentrations. One minute of expectoration after the suctioning procedures in children was a statistically significant method of further reducing oral fluoride retention to a clinically acceptable level (1.6 +/- 0.5 mg). We recommend that suction devices be used during topical fluoride treatments, but most importantly that the patients be requested to expectorate thoroughly after topical treatment.
本研究考察了在专业应用4分钟1.23%氟凝胶后，抽吸装置在减少口腔氟潴留方面的效果。还对儿童受试者的患者咳出情况进行了评估。在所有情况下，抽吸装置在减少口腔留存氟方面均为具有统计学意义的辅助手段；然而，抽吸程序后的口腔留存氟剂量在成人（10.3±2.3毫克）和儿童（7.7±1.0毫克）中仍有显著差异。这些口腔留存氟量会导致体液氟浓度大幅升高。儿童在抽吸程序后咳出1分钟是将口腔氟潴留进一步降低至临床可接受水平（1.6±0.5毫克）的具有统计学意义的方法。我们建议在局部用氟治疗期间使用抽吸装置，但最重要的是要求患者在局部治疗后彻底咳出。
