Abstract

Introduction: Many patients experience anxiety when they visit a dentist and anxiety causes an increase in the patient's blood pressure, as well as an injection of epinephrine, is also effective in increasing the blood pressure of the patients. The aim of this study was to investigate changes in blood pressure following injection of lower jaw blocking with lidocaine containing 1: 80000 epinephrine and its association with anxiety level in patients
Materials and Methods: In this cross sectional study, 129 patients referred to the dental school of Islamic Azad University of Khorasgan were selected and their blood pressure was measured before injection of anesthetic drug and ten minutes later. The anxiety level of the patients was determined using a dental anxiety inventory and the relationship between the level of anxiety and blood pressure in the patients before and after injection was measured. Data were analyzed by T-paired statistical test, regression and Pearson test.
Results: There is a positive correlation between the patient's systolic and diastolic blood pressure before the injection and the anxiety score is significant (p value < 0.001). There was also a significant association between the degree of correlation between mean pressure and anxiety score (p value < 0.001). There was a positive and significant correlation between injection pressure and anxiety scores. (p value < 0.001).
Conclusion: Lidocaine injection containing epinephrine 1: 80,000 in patients undergoing mandibular block is associated with a significant increase in patients' systolic blood pressure. There was also a significant relationship between patients 'levels of anxiety and blood pressure, which had a greater effect on patients' blood pressure than epinephrine injections.
