Abstract
ABSTRACTAims The periodontal ligament injection in isolated areas of the mandible was clinically evaluated us-ing only a conventional dental cartridge syringe. Materials and Methods: One hundred subjects requir-ing extractions of either premolars or molars participated in the study. Results: A high percentage of success rate (85%) was achieved but with unfavorable comment from the patient in regard to a painful injection. Duration of surgical anesthesia following the injection proved to be adequate in almost all extractions performed. Conclusions: New devices for performing this injection appear to have some advantage over the conventional syringe technique. However, these devices were unfortunately unavail-able at the area of study. Further studies are recommended to further evaluate its success and also to determine the response of both the periodontal ligament and pulpal tissue in cases were restorative treatment of teeth is to be undertaken for example crowns, bridges and fillings
