Résumé
Dentists earnestly try to practice painless treatment. Conventional inferior alveolar nerve block technique is preferred by most of the dentists despite its various modifications.However its failure rate as per literature is quite high. Inexperienced dentists face difficulty in obtaining effective anesthesia. This may be due to limited access to inferior alveolar nerve,greater density of alveolar bone,bulky soft tissues,damage to nerve or due to risk of intravascular injection. The aim of this study is to review and clinically assess the factors causing difficulty or failure of inferior alveolar nerve block in predoctoral students and to review the mandibular nervve blocks. Dental interns of riyadh elm university were monitored during administration of inferior alveolar nerve block for difficulty factors influencing inferior alveolar nerve block. Onset of anesthesia, efficacy anesthesia of inferior alveolar nerve, lingual nerve and long buccal nerve were ascertained. Difficulty index was used to assess the "item difficulty" with a score of 0.0 which indicates that none of the dental interns anesthetised correctly to 1.0 suggesting all the dental interns anesthetised correctly. Complete failure of inferior alveolar nerve block was noticed in 2.4% of predoctoral students. The most common cause for inferior alveolar nerve block failure was attributed to the difficulty in palpating the landmarks (77%), 22% of the patients refused multiple needle penetrations,and 19% of inferior alveolar nerve block failure was due to the fear of potential complications by the predoctoral students. Clinical skill of predoctoral students need adequate training in nerve blocks. Revising the current literature on alternative inferior alveolar nerve block techniques or use of evidence based dentistry to update and practice alternative nerve block techniques would aid in improving the clinical skills and treatment outcome which would therefore enable to remove the stumbling blocks in successful anesthesia.
