Title of Study: The Effect of Different Vasoconstrictive Agents on Hemodynamics Among Patients Undergoing Simple Mandibular Exodontia: A Triple-Blind Randomized Controlled Trial Location: King Abdulaziz University Dental Hospital (KAUFD), Jeddah, Saudi Arabia What Is This Study About? This study examines two types of vasoconstrictive agents used alongside local anesthetic during simple lower tooth extractions: * Epinephrine (1:100,000) * Epinephrine Bitartrate (1:55,000) What are vasoconstrictors? Vasoconstrictors help control bleeding and extend the numbing effect during dental procedures. They are usually added to local anesthetics (numbing agent) during dental procedures. This research aims to answer the following questions: 1. Which one of the vasoconstrictive agents has less effect on the heart rate and blood pressure 2. Which one offers better pain control? Who Can participate? * Adult patient +18 year/old or above (healthy or with well-controlled conditions like hypertension) * Patients who require non-surgical lower tooth extractions * Procedures will be done by supervised fifth and sixth-year dental students Potential Risks and Discomforts Like any medical procedure, there are some potential risks, including: From the anesthesia and vasoconstrictors: * Allergic reaction * Prolonged numbness * Changes in blood pressure and heart rate From the tooth extraction itself: * Bleeding * Pain or discomfort * Swelling or bruising * Infection * Dry socket * Delayed healing * Damage to nearby teeth or tissues * Fracture of the tooth or jawbone * Numbness or altered sensation (temporary or permanent) * Sinus complications (in upper tooth extractions) * The need for additional procedures Potential Benefits * Free tooth extraction * Blood pressure monitoring - with referral to a primary care provider if undiagnosed high blood pressure is detected Costs There are no additional costs to participate in this research. Treatment and extraction are provided free of charge. Compensation / Treatment for Injury If a participant is injured as a result of being in this study: * Necessary treatment and medical care will be provided by the research team. * No financial compensation is available from King Abdulaziz University Dental Hospital (KAUFD). Confidentiality Participants' identity and medical information will be kept confidential. Only authorized researchers and relevant oversight bodies may access Participants' medical/dental records for monitoring or auditing purposes, in accordance with laws and regulations. Any published results will not identify the participants.

A standard vasoconstrictor-containing local anesthetic used in dental procedures to minimize bleeding and prolong anesthetic effect.
An alternative formulation of vasoconstrictor-containing local anesthetic evaluated for its safety and analgesic effectiveness in dental extractions.

Change in Systolic and Diastolic Blood Pressure
To compare changes in systolic and diastolic blood pressure between the two groups (epinephrine vs. epinephrine bitartrate) at three time points: before administration of local anesthesia, 3 minutes after administration (intraoperative), and postoperatively following simple mandibular tooth extraction.
Time frame: Measured preoperatively, 3 minutes post-anesthesia (intraoperative), and immediately after the procedure (postoperative).
Change in Heart Rate
To evaluate changes in heart rate between the two intervention groups across the same three time points to assess the hemodynamic impact of the vasoconstrictors used.
Time frame: Measured preoperatively, 3 minutes post-anesthesia (intraoperative), and immediately after the procedure (postoperative).
Pain Score Using Visual Analogue Scale (VAS)
To compare pain perception during and after the dental procedure between the two groups using a 10-point Visual Analogue Scale (VAS). Patients reported pain at 30-minute intervals throughout the procedure and at the end of treatment. The minimum value on the VAS is 0 and the maximum is 10.
Time frame: Assessed every 30 minutes during the procedure and once at the completion of the extraction.
