本临床实验选３０例儿童，年龄从４岁到９岁，患下颌乳磨牙牙髓炎，需行失活干髓术。按就诊顺序随机分成两组，使用自身对照方法：单数组（Ａ组）初诊给予暗示信号，在治疗时收集唾液，复诊时给予空白信号，同样收集唾液。双数组（Ｂ组）反之。实验结果经统计学处理，暗示组与对照组相比，两者差别有高度显著性（ｔ＝５．２９５５，ｐ＜０．００００１），证明暗示法在儿童牙病治疗中有显著抑制唾液分泌作用，是一种可行的隔湿方法。
The clinical trials selected 30 cases of children, aged from 4 to 9 years old, suffering from mandibular molars dental pulp, in need of in-line dry pulp surgery. The patients were randomly divided into two groups according to the order of treatment. The self-control method was used. A single group (group A) was initially given the suggestive signal, saliva was collected during treatment, and a blank signal was given at the time of referral. Saliva was also collected. Double array (group B) and vice versa. The results of the experiment were statistically analyzed, suggesting that the difference between the two groups was highly significant (t = 5.2955, p <0.00001), indicating that the suggestive method significantly inhibits salivary secretion in children with dental treatment Role, is a viable wet method.
