Study Design:
The mouth will be split in half using a split mouth study. The lower anterior teeth will be injected with a conventional local anesthetic syringe on one side, and the patient will be injected with an electronic anesthetic syringe on the other side.
The study will be conducted on a sample of volunteers aged 18 to 30 years at the Faculty of Dentistry at Al-Andalus University.
The objectives and procedure will be explained to each group of patients, and informed consent will be obtained from each patient to accept the research procedures.
A 2% non-vasoconstrictor lidocaine local anesthetic will be used for all patients.
