Treatment of Maxillary Sinusitis of Odontogenic Origin: A Case Series.

Odontogenic infection is a possible cause of maxillary sinusitis. In this case series, the authors evaluated patients who presented with maxillary sinusitis symptoms before and after dental treatment. Intraoral periapical radiographs and cone-beam computed tomography (CBCT) scans were performed on three patients whose maxillary sinusitis symptoms included pain, sinus congestion, respiratory complaints, and what appeared on CBCT to be sinus mucosal thickening.

Technologic advances in endodontics.

This article addresses technologic advances in endodontics pertaining to new and emerging technology. Cone-beam computed tomography and optical occurrence tomography are 2 new imaging technologies that can assist the practitioner in the diagnosis of pulpal disease. The self-adjusting file and the Apexum device can be used for instrumentation and bulk debridement of an apical lesion, respectively.

Mandibular first molars with three mesial canals.

Five clinical cases demonstrate the presence of a middle mesial canal in the mandibular first permanent molar. This is not an extra canal but rather the sequelae of instrumenting the isthmus between the mesiobuccal and mesiolingual canals.
