Regional Nerve Blocks for Equine Dentistry.

This research article focuses on the procedures for implementing regional nerve blocks for dental surgery procedures in standing, sedated horses.

Overview

The abstract discusses the necessity of regional nerve blocks for equine oral surgeries, providing a step-by-step procedure for common nerve blocks such as infraorbital, maxillary, middle mental, and inferior alveolar nerve blocks. Emphasizing the importance of the procedure, the authors claim that regional nerve blocks are integral to conducting dental surgery on horses.

• Infraorbital and Maxillary Nerve Blocks: The infraorbital and maxillary nerve blocks are needed for providing anesthesia to the infraorbital nerve, a branch of the maxillary nerve. This allows for conducive anesthesia during maxillary dental procedures.
• Injection Process: Special care must be given while injecting the infraorbital nerve block, as the needle needs to precisely enter the infraorbital foramen to successfully anesthetize the caudal maxillary teeth.

Mandibular Procedures

For procedures on the mandible, anesthesia from the inferior alveolar nerve, a branch of the mandibular nerve, is required.

• Local Anesthesia: Local anesthesia at the mental foramen level results in anesthesia of the ipsilateral incisors and canines.
• Anesthesia at Mandibular Foramen Level: An anesthesia at the mandibular foramen level is required to anesthetize the whole mandibular dental quadrant on the same side.

Preparation and Execution

Aseptic preparation of the injection site prior to the procedure is crucial. The abstract then provides a detailed, step-by-step process for the four most common dental nerve blocks.

Remarkably, the authors successfully provide an exhaustive, yet simple guide for an essential equine oral surgical procedure. They meticulously enumerate each step, enhancing the overall understanding and implementation of the nerve block process.
