Case ReportsTumor-induced osteomalacia associated with a maxillofacial tumor producing fibroblast growth factor 23: report of a case and review of the literature.
Tumor-induced osteomalacia (TIO) is a rare acquired paraneoplastic disease characterized by renal phosphate wasting and hypophosphatemia. Recently, it was reported that tumors associated with TIO produce fibroblast growth factor (FGF) 23, identified as the last member of the FGF family and of which excessive action causes several hypophosphatemic diseases whereas deficient FGF23 activity results in hyperphosphatemic tumoral calcinosis. In this case, although it was difficult to locate the associated tumor, an abnormal mass in the left maxilla was detected by imaging. ⋯ Histopathologic diagnosis of the tumor was phosphaturic mesenchymal tumor, mixed connective tissue variant. Immunohistochemical findings confirmed that the removed tumor produced FGF23. These results indicate that development of osteomalacia in this patient was related to the maxillary tumor, which overexpressed FGF23.

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.

Randomized Controlled TrialThe closure of oroantral communications with resorbable PLGA-coated beta-TCP root analogs, hemostatic gauze, or buccal flaps: a prospective study.
The aim of this study was to compare the treatment of oroantral communications (OACs) with bioresorbable root analogs made of poly(lactide-co-glycolide) (PLGA)-coated beta-tricalcium phosphate (beta-TCP), hemostatic gauze or a buccal flap technique. ⋯ Closures of OACs with PLGA-beta-TCP composite or hemostatic gauze are reliable minimally invasive methods that minimize atrophy of the alveolar ridge, swelling, and pain compared with a buccal flap technique.

Postoperative recovery after removal of a lower third molar: role of trait and dental anxiety.
The aim of this study was to evaluate trait and dental anxiety influence on postoperative recovery after lower third molar surgery and to determine the effect of anxiety on surgery duration. ⋯ Patients with high trait or dental anxiety may tend to require longer surgery times and have poorer postoperative recovery.
