Pak Oral Dental J Jan ;41(2):73-5.

The objective of this research was to assess how aware house officers and post graduate trainees are about periodontal ligament injections. 150 questionnaires were distributed but only 105 responses were received. The questionnaire consisted of 10 questions in which participants were asked basic questions about injection technique for extractions and knowledge about periodontal ligament injection. All 105 responses were sent for statistical analysis. Out of 105 participants; 49.5% used nerve infiltration, 35.2% used nerve block, 13.3% used both and 1% used periodontal ligament injection for extraction. The technique used for effective anaesthesia for extraction of tooth was nerve block 82.8%, periodontal ligament injection 7.6%, 6.7% Nerve infiltration, 2.9% pulpal injection. It is concluded that many house officers and post graduate trainees know about the PDL injection but they apply this method of anesthesia in circumstances when the routine infiltration and block (IANB) fail to be effective.
