To determine whether adult patients' dental anxiety levels decrease following exodontia carried out under inhalational conscious sedation with nitrous oxide and oxygen (IHS) and local anaesthetic (LA).
Retrospective analysis of pre- and post-operative modified dental anxiety score (MDAS) questionnaires completed by patients treated in a primary care oral surgery service between 21 July 2010 and 17 December 2010.
138 patients who had undergone exodontia were divided into three groups: moderate to severe anxiety (MDAS scores 11-25) treated under IHS and LA (n = 60), mild anxiety (MDAS scores 5-10) treated under IHS and LA (n = 43) and mixed anxiety (MDAS scores 5-15) treated under LA only (n = 35). The mean pre- and post-operative MDAS scores were analysed by means of one-tailed, paired t-tests.
The moderate to severely anxious group treated under IHS and LA showed a statistically significant decrease of 3.68 between the mean pre- and post-operative MDAS scores (p = 0.000). The IHS mildly anxious group showed a decrease of 0.07 (p = 0.392) and the LA group showed a decrease of 0.23 (p = 0.227). Neither of these results were statistically significant.
These results support the use of IHS, to reduce anxiety of exodontia, in moderate to severely anxious adults undergoing minor oral surgery (MOS) procedures under LA in primary care oral surgery.
确定在氧化亚氮和氧气吸入性镇静（IHS）和局部麻醉（LA）下拔牙后，成年患者的牙科焦虑水平是否降低。
对 2010 年 7 月 21 日至 2010 年 12 月 17 日在初级保健口腔外科服务中接受治疗的患者在术前和术后完成的改良牙科焦虑量表（MDAS）问卷进行回顾性分析。
将 138 名接受拔牙的患者分为三组：中重度焦虑（MDAS 评分 11-25）在 IHS 和 LA 下治疗（n = 60），轻度焦虑（MDAS 评分 5-10）在 IHS 和 LA 下治疗（n = 43）和混合焦虑（MDAS 评分 5-15）仅在 LA 下治疗（n = 35）。通过单尾，配对 t 检验分析平均术前和术后 MDAS 评分。
在 IHS 和 LA 下治疗的中重度焦虑组，平均术前和术后 MDAS 评分之间有统计学显著降低 3.68（p = 0.000）。IHS 轻度焦虑组降低 0.07（p = 0.392），LA 组降低 0.23（p = 0.227）。这些结果均无统计学意义。
这些结果支持在初级保健口腔外科中，在 LA 下对接受小口腔手术（MOS）的中重度焦虑成年人使用 IHS 来降低牙科焦虑。
