    Mandibular defect reconstruction utilizing preoperative 3D modeling, plate pre-bending and a novel triad graft: a case report

    Jon D. Wagner , Jeffrey P. Wagner , Stephen A. Wagner
    The reconstruction of boney defects of the mandible are a challenge in surgical therapy despite advances in bone grafting. This case study details a 30-year-old female who sustained a gunshot wound to the mandible leaving a 5 cm boney defect. This defect was reconstructed utilizing preoperative three-dimensional (3D) planning, an accurately pre-bent reconstruction plate, and a novel “triad” construct of autogenous bone graft, demineralized bone matrix, and an osteoprotective membrane. This reconstruction workflow allowed maintenance of the contour of the mandible and bone regeneration while... Read more

    Dilemmatic presentation of linear IgA disease: a case report

    Roopashri Rajesh Kashyap , Gopakumar R. Nair , Rajesh Shanker Kashyap
    Linear IgA disease is a rare blistering disease affecting the skin and less often the oral mucosa. This disease has a varied clinical presentation especially when the disease affects the oral mucosa. Certain drugs, autoimmune diseases, infection, chronic renal insufficiency, and malignancies have been implicated as the etiologic factors of this disease. The gold standard for diagnosis of linear IgA disease is direct immunofluorescence on fresh tissue. The immunofluorescence will demonstrate a homogeneous linear deposition of immunoglobulin A along the basement membrane. Multiple therapeutic... Read more

    Polytimi P. Paschalidi , Nikolaos G. Nikitakis , Dimosthenis Igoumenakis , George Kostakis
    Papillary cystadenocarcinoma (CAC) a rare malignant salivary gland tumor which commonly arises in the major glands, mainly the parotid, and less frequently in the minor salivary glands. Localization in the sublingual salivary gland is very rare. The authors present a case of papillary CAC originating from the right sublingual gland in a 78-year-old female. A review of the literature revealed only 3 previously published detailed cases (in addition to 2 cases as part of larger series) of papillary CAC of the sublingual gland. The salient demographic, clinical, and histopathologic findings of... Read more

    A case of periradicular surgery: apicoectomy and obturation of the apex, a bold act

    Lino Lucio Locurcio , Rachel Leeson
    This paper reports a case of a recurrent periapical cyst treated with enucleation of the lesion, apicoectomy, and root end obturation on a lower left first molar. In the case of conventional root canal treatment failure, non-surgical retreatment is the preferred option in most of the cases. Several factors such as a complex root canal system or previous procedural accidents may impede the success of non-surgical retreatment. The authors have performed root-end resection and preparation under local anesthesia on a lower left first molar; The root canal filling is placed within the new cavity... Read more
