Clinical Trial Summary

The specific aims of the present study were to evaluate sAA responses to impacted third molar extractions at different time points in the patients under conscious sedation with local anesthesia and to examine the relationship between sAA, conscious sedation and dental anxiety. The null hypothesis was that conscious sedation could be considered to reduce salivary alpha amylase level during the wisdom tooth surgery.

Description:

In oral and maxillofacial surgery, surgical extraction of impacted third molars is one of the most common surgical techniques performed in the oral cavity. Conscious intravenous sedation could be administered for the patients to provide anxiolysis, sedation, and analgesia for the patient. Salivary alpha-amylase (sAA) which reflect stress-related changes in the autonomic nervous system (ANS), has been proposed as a non-invasive stress biomarker. The aim of the present study was to investigate whether salivary alpha amylase (sAA) levels could be decreased by conscious sedation in the patients undergoing impacted third molar extraction. A total of 18 male patients were recruited. All patients were administered Modified Dental Anxiety Scale (MDAS) test. Patients were divided into two groups: test group (procedures under sedation) and control group (procedures under local anesthesia). The following parameters were monitored at different study time-points: systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation (SO2), and heart rate (HR). Five samples of saliva were taken from each patient: the first time patient came to clinic, the patient sat in the chair for extraction, before local anesthesia, immediately after extraction, at 4 h after extraction. The concentrations of sAA were measured and compared across the different stages of the study between two groups.

Intervention

Procedure:
• Procedures of wisdom tooth removal surgery under conscious sedation
The first specimen of saliva was taken at the first time patient came to clinic (t1). Saliva was allowed to flow in the floor of mouth an 1 ml was then collected using a Pasteur pipette. First day after examination, patient was given an appointment. The second time of the saliva was taken was when the patient sat in the chair for extraction (t2). The other times of saliva samples were taken were before local anesthesia (t3), immediately after extraction (t4) and at 4 h after extraction (t5). Due to the localization and position of the third molar, osteotomy was performed using a 20,000-rpm hand piece under irrigation for all patients. Some cases required tooth sectioning. 3-0 silk suture was used at the end of the surgery.
