Case ReportsIatrogenic pneumomediastinum with extensive subcutaneous emphysema after endodontic treatment: report of 2 cases.
Pneumomediastinum with subcutaneous emphysema is a relatively rare complication of dental treatment. The most common dental etiology of this complication is the introduction of air via the air-turbine handpiece during surgical extraction of an impacted tooth, but this complication is very rare after nonsurgical endodontic treatment. We report herein 2 cases of massive pneumomediastinum and cervicofacial subcutaneous emphysema that developed after opening an access cavity for endodontic retreatment. We describe its etiologies and guidelines for the prevention of this complication during nonsurgical endodontic treatment.

Randomized Controlled TrialComparative evaluation of anesthetic efficacy of Gow-Gates mandibular conduction anesthesia, Vazirani-Akinosi technique, buccal-plus-lingual infiltrations, and conventional inferior alveolar nerve anesthesia in patients with irreversible pulpitis.
Conventional inferior alveolar nerve block (IANB) has a poor success rate in inflamed pulps. Three alternative techniques of providing anesthesia to mandibular molars were evaluated and compared with conventional IANB. ⋯ Gow-Gates mandibular conduction anesthesia may increase the success rates in patients with irreversible pulpitis compared with conventional IANB. None of the techniques provided acceptable success rates.
