Abstract(s)
O bloqueio do nervo alveolar inferior convencional é a técnica mais comumente utilizada para obtenção de analgesia pulpar em dentes posteriores inferiores e na região posterior da mandíbula. Contudo, esta técnica possui altos índices de insucesso, e estas taxas tornam-se ainda menores quando se tratam de pulpites agudas. A correta identificação das causas da falha anestésica dentária é essencial para adoptar as medidas necessárias para um bloqueio anestésico bem-sucedido. Este trabalho apresenta uma revisão acerca dos fatores anatómicos associados às falhas anestésicas do bloqueio do nervo alveolar inferior, com ênfase no papel do plexo cervical na inervação acessória do bordo posterior da mandíbula, através do nervo cervical transverso e do nervo grande auricular; bem como o canal mandibular bífido e as suas diferentes configurações anatómicas. As opções terapêuticas e evidências científicas disponíveis para uma melhor abordagem do bloqueio do nervo alveolar inferior serão discutidas.
Inferior alveolar nerve block is the most commonly technique used in order to obtain pulpal analgesia in lower posterior teeth and posterior region of mandible. However, this technique has high failure rates, and these rates become even lower when it comes to acute pulpitis. The correct identification of the causes of dental anaesthetic failure is essential to adopt the necessary path for a successful anaesthetic block. This paper presents a review of the anatomical factors associated with anaesthesia failure of the inferior alveolar nerve block, with emphasis on the role of the cervical plexus in the accessory innervation of the posterior border of the mandible, through the transverse cervical nerve and the great auricular nerve; as well as the bifid mandibular canal and its different anatomical configurations. The therapeutic options and scientific evidence available for a better approach to the inferior alveolar nerve block are discussed.
