Buccal Infiltration Anesthesia Versus Inferior Alveolar Nerve Block Anesthesia

Comparative Evaluation of the Effectiveness of Buccal Infiltration Anesthesia Versus Inferior Alveolar Nerve Block Anesthesia for the Extraction of Primary Mandibular Molars: A Randomized Controlled Study

This study aims to evaluate the effectiveness of single buccal local infiltration when compared to buccal local infiltration with intrapapillary infiltration and inferior alveolar nerve block anesthesia in primary mandibular molar extractions.

Effective pain control is essential in providing children with successful dental treatment. Without it, negative experiences may result in anxiety and fear-related behaviors towards subsequent dental treatment. Local anesthesia is the cornerstone of pain control in dentistry. Choosing the right local anesthetic technique is of special significance .

The inferior alveolar nerve block (IANB) is a common practice for anesthetizing mandibular molars and/or premolars on one side of the jaw. It is achieved by depositing local anesthetic solution at the entrance to the mandibular canal, which inhibits the transmission of action potentials along the inferior alveolar nerve.

Administering an IANB can be technique sensitive and failure rates are reported to be up to 20%, due to anatomical variations in the position of the mandibular foramen and accessory innervations. This effect may be compounded for those who are not used to anesthetizing children .

However, Supraperiosteal infiltration has the advantages of easier administration when compared to block anesthesia, shorter anesthetic duration, and generally does not anesthetize the lips .

An ideal local anesthetic should provide maximum efficacy, through a minimal number of injections, using techniques that provide the least discomfort, causing negligible adverse effects .

Inclusion Criteria:
