Analysis of blood pressure during tooth extraction

ABSTRACT

Introduction: Surgical procedures have a history of dental pain, apprehension and fear reported by patients. Because of these reasons, they trigger a series of modifications that lead to changes in blood pressure and stress occurrences. Objective: This study aimed to monitor changes in blood pressure pre-, trans-, and postoperatively and assess whether the differences would be significant. Material and methods: One hundred and ninety-four patients, both genders, aged between 14 and 65 who were undergoing surgery for tooth extraction were selected. They had their systolic and diastolic blood pressures measured at four different times preoperative (M1), post-anesthesia (M2), post-extraction (M3) and at the end, after the suture (M4), with the aid of a digital tensiometer. Results: There were statistically significant differences between systolic blood pressure changes among all times, except between M1 and M4. Concerning the diastolic blood pressure measurement, there were statistical differences among all times except between M1xM4 and M2xM3. Conclusion: There were changes in blood pressure between different moments of extractions.
