The purpose of this study was to systematically review the scientific literature concerning the effect of playing background music on anxiety and physiological parameters in patients undergoing dental treatment. MEDLINE-PubMed, Cochrane-CENTRAL, and EMBASE were searched for papers up to September 2020. Inclusion criteria were randomized clinical trials (RCTs) or controlled clinical trails (CCTs) among adolescents and adults that assessed anxiety (AX), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), or respiratory rate (RR). Data before and after treatment were extracted and the potential risk of bias was estimated. Descriptive analysis and meta-analysis were performed. Thirteen eligible studies (12 RCTs, 1 CCT) were retrieved, with an estimated low to high risk of bias. Descriptive analysis showed an effect on AX in favor of music intervention, while no effect on SBP and DBP was found. The effect on HR and RR was inconsistent among studies. Meta-analysis showed a significant difference of means (DiffM) for the end scores of AX (State-Trait Anxiety Inventory and Corah’s Dental Anxiety Scale (CDAS)) and incremental scores (CDAS) in favor of music intervention. Dental care professionals may consider playing background music while treating adolescent and adult patients. There is a moderate certainty that this can provide a small reduction in dental anxiety. With very low to moderate certainty, no effect on physiologic parameters can be expected.

这项研究的目的是系统地回顾有关播放背景音乐对正在接受牙科治疗的患者的焦虑和生理参数的影响的科学文献。检索MEDLINE-PubMed，Cochrane-CENTRAL和EMBASE直至2020年9月的论文。纳入标准为评估焦虑（AX），收缩压（ SBP），舒张压（DBP），心率（HR）或呼吸率（RR）。提取治疗前后的数据，并估计潜在的偏倚风险。进行描述性分析和荟萃分析。检索了13项符合条件的研究（12篇RCT，1篇CCT），估计有偏低的风险。描述性分析表明，对AX的影响有利于音乐干预，而对SBP和DBP则没有影响。在研究之间对HR和RR的影响不一致。荟萃分析显示，AX的最终得分（状态特质焦虑量表和Corah牙科焦虑量表（CDAS））和增量得分（CDAS）在音乐干预方面的均值（DiffM）存在显着差异。牙科保健专业人员可能会在治疗青少年和成人患者时考虑播放背景音乐。可以肯定地说，这可以使牙科焦虑症有所减少。具有非常低至中等的确定性，不会对生理参数产生影响。荟萃分析显示，AX的最终得分（状态特质焦虑量表和Corah牙科焦虑量表（CDAS））和增量得分（CDAS）的平均得分（DiffM）有显着差异，有利于音乐干预。牙科保健专业人员可能会在治疗青少年和成人患者时考虑播放背景音乐。可以肯定地说，这可以使牙科焦虑症有所减少。在非常低至中等的确定性下，预期不会对生理参数产生影响。荟萃分析显示，AX的最终得分（状态特质焦虑量表和Corah牙科焦虑量表（CDAS））和增量得分（CDAS）的平均得分（DiffM）有显着差异，有利于音乐干预。牙科保健专业人员可能会在治疗青少年和成人患者时考虑播放背景音乐。可以肯定地说，这可以使牙科焦虑症有所减轻。具有非常低至中等的确定性，不会对生理参数产生影响。可以肯定地说，这可以使牙科焦虑症有所减少。具有非常低至中等的确定性，不会对生理参数产生影响。可以肯定地说，这可以使牙科焦虑症有所减少。具有非常低至中等的确定性，不会对生理参数产生影响。
