Abstract
BackgroundSalivary alpha-amylase (sAA) activity is thought to be an indicator of mental stress. However, the relationship between sAA activity and mental stress in patients undergoing dental implant treatment has not been investigated. The present study aimed to examine the correlation between sAA activity and changes in the patient’s vital signs during dental implant surgery.ResultssAA activity was higher after surgery compared to the pre-surgical measurements. A significant positive correlation was observed between sAA activity and heart rate (HR) (rs=0.434, p=0.007), as well as the peripheral blood oxygen (SpO2) (rs=0.392, p=0.016).ConclusionsAA activity and the patient’s stress levels tended to increase after the surgical procedure. A positive correlation was observed between SpO2 and sAA activity. A significant positive correlation was also observed between the between the HR and sAA activity, although there was no correlation between blood pressure and sAA activity. Thus, sAA may be a valuable indicator of the stress and anxiety accumulated during dental implant surgery.

Salivary alpha-amylase activity is thought to be an indicator of mental stress
blood pressure (BP) is controlled by the autonomic nervous system, which includes the sympathetic nervous system (SNS) and parasympathetic nervous system (PSNANS); in other words, the stress level in an individual is modulated by the balance between the Parasympathetic nervous system (PSNANS) and SNS [10, 11]
The present study aimed to examine the anxiety and stress levels of patients who underwent dental implant surgery based on the activity of Salivary alpha-amylase (sAA) before and after the procedure, in addition to the evalution of their vital signs
Summary
Oral rehabilitation with dental implants is a widely used clinically effective and predictable modality for patients with complete or partial edentulism [1,2,3]. In addition to the cornerstone implant placement surgery, dental implant treatment requires different surgical techniques, such as bone augmentation, soft tissue management, or a second surgery to deliver the healing abutment, depending on each individual case [4] These procedures may induce psychological and physiological stress in patients, which can be controlled in several cases, so that patients exhibit normal clinical conditions before and during surgical implant treatment [5, 6]. The present study aimed to examine the anxiety and stress levels of patients who underwent dental implant surgery based on the activity of sAA before and after the procedure, in addition to the evalution of their vital signs. The measurement of sAA activity acted as an adjunctive indicator for stress and anxiety and we assessed the relationship and correlation between sAA and these vital signs to test this hypothesis
