Pak Oral Dental J Jan ;37(4):551-6.

The objective of this study was to evaluate the interest and appreciation among dental practitioners of the importance of refreshing their knowledge from the available literature regarding the most frequently performed procedure i.e administration of local anesthesia, applicable to all fields of dentistry. A 2 component questionnaire was designed directed towards information regarding frequency and cause of failure of inferior alveolar nerve block in the participants’ understanding, how frequent the participants refresh their knowledge from a reference book of local anesthesia and some technical questions regarding local anesthesia in mandible. The questionnaire was first pilot tested with 10 teaching faculty members and then distributed to 242 practicing dentists. Data were entered and analyzed using SPSS version 16. The relationship between the professional status with the rate of local anesthesia failure and interest in refreshing the knowledge were analyzed using Kruskal Wallis Test. Only 15.3% participants claimed that they had never experienced failure of inferior alveolar nerve block. No significant relationship was found between the professional status and the frequency of failure of inferior alveolar nerve block. It was concluded that 16.5% participants claimed that they often revise the anatomical landmarks and no significant relationship was found between the professional status and the interest of the participants in revision of anatomy.
