This study investigated the influence of nitrous oxide on treatment time when it is used as an additional aid to behavior management. Different parts of the treatment of highly anxious child dental patients may vary during sequential dental visits, and separate consecutive parts of the treatment were considered in terms of their duration. Fifty-six children between the ages of six and eleven, each with a previous negative dental experience, were selected. They were randomly assigned into one of two matching groups: one with behavioral management only (control); the other also having nitrous oxide sedation (experimental). Interval 1, involved getting used to the procedures; interval 2 was sedation; interval 3, local anesthesia; and interval 4, preparation and filling. Most children required between four and six sessions. Results show that in terms of total treatment time (TTT), the use of nitrous oxide does not save time, although dental treatment did not require a greater number of sessions. For the dentist to erase the negative imprint of a previous dental experience, special skills are required. Further research is advised concerning the anxiety levels of this age-group.
本研究调查了一氧化二氮作为行为管理辅助手段时对治疗时间的影响。在连续的牙科就诊过程中，高度焦虑的儿童牙科患者治疗的不同部分可能会有所不同，并且根据治疗的连续部分的持续时间进行了考虑。选择了56名年龄在6至11岁之间、之前有过负面牙科经历的儿童。他们被随机分为两个匹配组之一：一组仅采用行为管理（对照组）；另一组同时采用一氧化二氮镇静（实验组）。阶段1是适应程序；阶段2是镇静；阶段3是局部麻醉；阶段4是准备和补牙。大多数儿童需要4至6次就诊。结果表明，就总治疗时间（TTT）而言，使用一氧化二氮并不能节省时间，尽管牙科治疗所需的就诊次数并没有增加。为了消除儿童之前牙科经历的负面印记，牙医需要特殊技能。建议针对该年龄组的焦虑水平进行进一步研究。
