Extra oral sinus of odontogenic origin occurs when the purulent by-products of dental pulp necrosis spread along the path of least resistance from the root apex to the skin on the face. Patients presenting with cutaneous sinus usually visit a general physician or dermatologist first, as the lesion can mimic various dermatologic pathologies, ranging from an infected sebaceous cysts to a basal cell carcinoma. Despite systemic antibiotics, symptoms often persist causing further confusion, and at times leading to unnecessary surgical interventions. The location of this sinus in the head and neck region should lead the physician to seek a dental opinion in order to avoid misdiagnosis.
Placental mesenchymal dysplasia (PMD) is an uncommon vascular anomaly of the placenta characterized by placentomegaly with multicystic placental lesion on ultrasonography and mesenchymal stem villous hyperplasia on histopathology. Placental mesenchymal dysplasia should be considered in the differential diagnosis of cases of multicystic placental lesion such as molar pregnancy, chorioangioma, subchorionic hematoma, and spontaneous abortion with hydropic placental changes. However, lack of high-velocity signals inside the lesion and a normal karyotype favor a diagnosis of PMD. PMD must be differentiated from gestational trophoblastic disease because management and outcomes differ. We report the case of an 18-year-old female at 15 weeks of gestation with sonographic findings suggestive of placental mesenchymal dysplasia. The diagnosis was confirmed on histopathology.
Introduction: This in-vitro study aimed to test the accuracy and reproducibility in detection of incipient occlusal caries and treatment decision making using unenhanced visual-tactile technique and low level magnification by the use of loupes and surgical operating microscope (SOM).Methodology: Sixty extracted human posterior teeth were assessed by two examiners using ICDAS-II index and CPI-TN probe, with and without magnification. Histopathology was used as gold standard for diagnosis of caries and treatment decision making. Inter and intra examiner reproducibility was determined using Kappa statistics.
Root fracture has been defined as a fracture involving dentin, cementum, pulp and periodontal ligament. Depending on the level of the fracture line various treatment modalities may be employed by the clinician to promote healing. The following case reports highlight how changes in technique allow for conservative management of horizontal root fractures at different levels. This approach allows the patient to retain their natural dentition at an affordable cost and provide a viable alternative to the use of more invasive and expensive alternatives. These patients presented with complaints of pain and mobility in upper front tooth region following trauma. Diagnosis was confirmed on the basis of intra-oral periapical radiographs following which non-surgical root canal treatment was performed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
