background and aims. current infiltration techniques for achieving anesthesia in dental procedures are not applicable in posterior mandibular region because of its dense cortical bone. the aim of this study was to evaluate the efficacy of a specific infiltration anesthesia in posterior mandibular teeth instead of inferior alveolar nerve block for restorative procedures. materials and methods. c...

background and aims. inferior alveolar nerve block injection is one of the common intra oral anesthetic techniques, with a failure rate of 15-20%. the aim of this study was to evaluate the position of the lingula as an index for this injection. materials and methods. thirty eight panoramic radiographs of 7–11 year old patients were analyzed and the distance between the lingula index and occlusa...

background in spite of common usage of the inferior alveolar nerve block (ianb), this method has some well-defined restrictions. objectives the purpose of the present study was to compare these two techniques for the surgical removal of impacted lower third molars. patients and methods a total of 44 similarly impacted lower third molars (22 patients with two similar teeth) were selected. in eac...

background and aims . dentists administer thousands of local anesthetic injections every day. injection to a highly vascular area such as pterygomandibular space during an inferior alveolar nerve block has a high risk of intravascular needle entrance. accidental intravascular injection of local anesthetic agent with vasoconstrictor may result in cardiovascular and central nervous system toxicit...

most often in the posterior of the mandible of patients who need implants, the inferior alveolar nerve (ian) is too high to insert the implants, and the surgeons have to reposition ian. in conventional techniques (to make the windows in the buccal aspect of the mandible) removal of the corticocancellous bone may cause weakness of the mandible. here we present a new technique in which the bone i...

Precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. Recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. In this study, the spatial relationship of two surgi...

Inferior alveolar nerve block obtained maximum anesthetic effect using a small dose of local anesthetic agent, which also has low a complication incidence. Complications of an inferior alveolar nerve block include direct nerve damage, bleeding, trismus, temporary facial nerve palsy, and etc. Among them, the major iatrogenic complication is dental needle fracture. A fragment that disappears into...
