Psychosomatic indicators, such as heart rate (HR), salivary alpha amylase (sAA) activity, and behavior, can be used to determine stress. This study's aim was to assess the pattern of changes of salivary alpha amylase, heart rate, and cooperative behavior in previously naïve children receiving dental treatment under local anesthesia.
Included were 30 children with no prior dental experience who needed 4 or more sessions of dental treatment involving local anesthesia. In each session, sAA, HR, and behavior were assessed before and during the application of local anesthesia and at the end of the treatment.
The highest sAA value was always observed at the end of each session; overall, the value was lower in the fourth session. HR always increased during the local anesthesia, and did not vary across sessions. No significant relationship was found between child cooperation and either sAA or HR.
In this sample, child cooperation may not be an accurate indicator of stress. Based on salivary alpha amylase activity changes, dental treatment involving local anesthesia in naïve children appeared to be less stressful after 3 sessions.
诸如心率（HR）、唾液α淀粉酶（sAA）活性及行为等身心指标可用于测定压力。本研究旨在评估首次接受局部麻醉下牙科治疗的儿童唾液α淀粉酶、心率及合作行为的变化模式。
纳入30名无既往牙科治疗经历且需要4次或更多次局部麻醉下牙科治疗的儿童。在每次治疗中，于局部麻醉应用前、应用期间及治疗结束时评估sAA、HR及行为。
每次治疗结束时sAA值始终最高；总体而言，第四次治疗时该值较低。局部麻醉期间HR始终升高，且各次治疗间无变化。未发现儿童合作与sAA或HR之间存在显著关系。
在本样本中，儿童合作可能并非压力的准确指标。基于唾液α淀粉酶活性变化，首次接受治疗的儿童在3次治疗后接受局部麻醉的牙科治疗似乎压力较小。
