Geminated Supernumerary Premolar Impacted in the Palate: A Report of a Rare Case and Review of the Literature.

Supernumerary teeth are dental anomalies characterized by the presence of an excessive number of teeth in relation to normal dentition. Among these, the supernumerary premolars have a prevalence of 0.29% to 0.

The Palatal Elevation Technique (PET) for Intra-alveolar Extraction of Grossly Decayed Maxillary Third Molars.

Intra-alveolar extraction of maxillary third molars always poses a challenge to dental practitioners owing to limited accessibility and minimal space for dental forceps application. Dental elevators facilitate the extraction of such teeth. In the traditional technique as described in the literature, the elevator is always introduced from the mesiobuccal aspect of the tooth to engage the space between the interdental bone and the offending tooth to use it as a fulcrum.

Applicability of the USPSTF Lung Cancer Screening Guidelines in a Predominantly Black Veteran Population.

Background: Black individuals and veterans are at higher risk for developing lung cancer compared with that of the general population. Evidence suggests the screening criteria have been too conservative for this population.

Methods: This study is a retrospective chart review examining the applicability of the 2013 United States Preventive Services Task Force lung cancer screening guidelines in a US Department of Veteran Affairs institution that served a a predominantly black population.

Cone-Beam Computed Tomography-Guided Electromagnetic Navigation for Peripheral Lung Nodules.

Background: Electromagnetic navigation bronchoscopy (ENB) is a minimally invasive technology for the diagnosis of peripheral pulmonary nodules. However, ENB is limited by the lack of real-time confirmation of various biopsy devices. Cone-beam computed tomography (CBCT) could increase diagnostic yield by allowing real-time confirmation to overcome the inherent divergence of nodule location.

HIV-associated large aggressive extranodal lymphoma of the oral cavity.

Malignant lymphomas form a heterogeneous group of neoplasms of the lymphoid tissue with different clinical courses, depending on the treatment and the prognosis. Human immunodeficiency virus (HIV) infection and acquired immune deficiency syndrome (AIDS) have been associated with an increased risk for the development of lymphoproliferative disorders. The incidence of lymphoma is associated with 60-fold increase in seropositive patients as compared to seronegative patients.

A comparative analysis of odontogenic maxillofacial infections in diabetic and nondiabetic patients: an institutional study.

Objectives: The increased prevalence of antibiotic resistance is an outcome of evolution. Most patients presenting with odontogenic space infections also have associated systemic co-morbidities such as diabetes mellitus resulting in impaired host defense. The present study aims to compare the odontogenic spaces involved, antibiotic susceptibility of microorganisms, length of hospital stay, and the infl uence of systemic comorbidities on treatment outcome in diabetic patients.

Mandibular metastasis from a pulmonary squamous cell carcinoma.

Metastatic tumors to the jaws and oral tissues are rarely encountered, accounting for less than 1% of all malignant tumors affecting the mouth. Although, metastasis to the mandible from a pulmonary carcinoma is extremely rare, when it does occur it mimics more common pathoses such as odontogenic cysts, osteomyelitis, space infections making its diagnosis even more challenging. Metastasis should be taken into account especially in patients with chronic history of smoking and sudden onset of paresthesia.
