Assessment of Maxillary Local Anesthesia Infiltration Using Needle-free Jet vs Conventional Syringe in Tooth Extraction

Assessment of Maxillary Local Anesthesia Infiltration Efficiency and Adult Patient Satisfaction: Needle-free Jet vs Conventional Syringe in Simple Tooth Extraction in a Single-blinded, Randomized Controlled Trial

Managing pain and anxiety during dental anesthesia remains a key concern, particularly in procedures involving needle-sensitive adult patients. Needle-free jet injection systems, such as Comfort- InTM, offer a potential alternative to conventional syringes by minimizing invasiveness and enhancing patient comfort during simple tooth extractions.

the study aimed to compare the efficacy, patient comfort, and pain perception between the conventional syringe injection technique and the needle-free jet injection system (Comfort-In) in dental anesthesia for simple tooth extractions.

Inclusion Criteria:

• KAUDH patients aged 18 to 65 years.
• Bilateral posterior dentition suitable for the split-mouth technique.
• Classified as American Society of Anesthesiologists (ASA) I or ASA II.

Exclusion Criteria:

• Pediatric patients (<18 years).
• Medically compromised individuals.
• Patients with unilateral teeth indicated for extraction,
• Patient with upper anterior teeth requiring a nasopalatine nerve block.
• Patient with lower teeth requiring a nerve block.
