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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Epinephrine Group (1:100,000)
Participants in this group received local anesthesia consisting of 2% mepivacaine hydrochloride with 1:100,000 (0.01 mg/mL) epinephrine prior to simple mandibular tooth extraction. This arm served as the comparator for evaluating hemodynamic changes and pain control.
2% Mepivacaine with 1:100,000 epinephrine
A standard vasoconstrictor-containing local anesthetic used in dental procedures to minimize bleeding and prolong anesthetic effect.
Epinephrine Bitartrate Group (1:55,000)
Participants in this group received local anesthesia consisting of 2% mepivacaine hydrochloride with 1:55,000 (0.018 mg/mL) epinephrine bitartrate prior to simple mandibular tooth extraction. This arm was evaluated for its effects on hemodynamic parameters and pain perception compared to standard epinephrine.
2% Mepivacaine with 1:55,000 Epinephrine Bitartrate
An alternative formulation of vasoconstrictor-containing local anesthetic evaluated for its safety and analgesic effectiveness in dental extractions.
