Florid OD, OF, and FD were the most common diagnoses, and the clinicopathologic and radiologic features were somewhat distinct from the characteristics of other populations.

Avascular bone necrosis is a serious oral side-effect of cancer chemotherapy, particularly in patients using biphosphonates, and antibiotic therapy and surgical debridation were not able to promote complete response in most cases.

The aim of this report was to present a case of endodontic sealer extrusion into the mandibular canal in a 42-year-old woman. The patient was referred to the Endodontology and Stomatology Clinics, School of Dentistry, Estácio de Sá University, complaining of 5-day duration intense spontaneous pain and paraesthesia, both arising after an endodontic intervention. Conventional radiographs and computed tomography of the mandible showed the presence of radiopacities inside the right mandibular canal. History and these radiographs confirmed extrusion of endodontic sealer. Treatment included an anti-inflammatory drug, completion of endodontic treatment and follow up. The patient reported gradual improvement, becoming asymptomatic after 2 months. Radiographs 30 months after initial examination revealed partial resorption of the foreign material. In conclusion, iatrogenic extrusion of endodontic materials should be included in differential diagnosis of endodontic pain and can sometimes be managed through non-surgical interventions in some cases.

The aim of this study was to report the frequency and clinical-radiological features of cases of lingual cortical mandibular bone depressions (LCMBD) diagnosed in consecutive panoramic radiographs and cone-beam computed tomography (CBCT) scans from a Brazilian population. The methods included a retrospective analysis of consecutive panoramic radiographs, charts from the Oral Medicine clinic and consecutive CBCT scans. All cases diagnosed as LCMBD were selected and clinical-radiological data were retrieved from the clinical charts and by the analysis of the image exams. Twenty LCMBD cases diagnosed in 18 patients were found, including 2 from 3,000 consecutive panoramic radiographs (0.07%), 6 from 2,421 Oral Medicine patients (0.25%) and 10 from 1,684 CBCT scans (0.59%). The 18 patients had a mean age of 51.5 years and 13 were males. Two patients presented bilateral lesions. Fourteen images (70%) were classified as well-defined. Eighteen affected the posterior area of the mandible and two affected the anterior mandible. Size of the lesions was larger in younger patients. In conclusion, there seemed to be a considerable radiological heterogeneity when comparing the LCMBD cases and it seemed that the images decreased in size with the increase of patient's age.

Although sarcoidosis is a systemic disease that rarely affects the gingiva, the possibility of gingival involvement as the sole manifestation of the disease should be considered in the differential diagnosis of gingival lesions.
