Pain During Infiltration Injection in Anterior Maxillary Region by Transcodent Painless Needle Tips Versus Regular Needle Tips

This randomized split-mouth controlled clinical trial will compare pain experienced during anterior maxillary infiltration anesthesia using Transcodent painless needle tips and conventional dental needle tips. Sixty adult patients requiring bilateral maxillary anterior infiltration anesthesia will receive injections with both needle types in a randomized order. Pain perception will be assessed immediately after each injection using a 100-mm Visual Analog Scale (VAS). The study aims to determine whether the Transcodent needle tip reduces injection-related pain compared with a conventional needle tip, thereby improving patient comfort during routine dental procedures.

Inclusion Criteria: Adults aged 18 to 60 years. Patients requiring bilateral maxillary anterior infiltration anesthesia for dental treatment. Patients undergoing endodontic procedures involving maxillary canines or premolars. Presence of healthy maxillary teeth on both sides suitable for infiltration anesthesia. Individuals with no systemic disease or neurological disorder affecting pain perception. Ability to understand the study procedures and provide written informed consent. Both male and female participants. Exclusion Criteria: Pregnant or lactating women. Use of analgesics, sedatives, or other pain-modifying medications within the previous 12 hours. Known allergy or hypersensitivity to local anesthetics, benzocaine, lidocaine, or epinephrine. Presence of active infection, inflammation, swelling, or pathology at the injection site. Severe dental anxiety, needle phobia, or inability to cooperate with study procedures. Individuals unable or unwilling to provide informed consent.
