Challenging Differential Diagnosis of Mandible Angle Metastasis from Breast Cancer.

Breast cancer is the most common cancer in women and the second leading cause of cancer-related death. Breast cancer manifestations in the head and neck are relatively rare, and they are mostly bony metastasis to the mandible and maxilla. In this paper, we present a case report of a metastatic tumor in the mandibular angle originating from breast carcinoma.

Evaluation of the Oral Microcirculation in Patients Undergoing Anti COVID-19 Vaccination: A Preliminary Study.

Videocapillaroscopy allows the study of both the morphological and architectural structure of the microcirculation and its hemodynamic conditions; these parameters are directly involved in autoimmune and/or inflammatory pathologies. The purpose of this research, based on capillaroscopy, is to establish whether a patient who receives an anti-COVID 19 vaccine has any changes in their oral microcirculation. A complete capillaroscopic mapping of the oral cavity of the subjects examined was made; the investigated mucosa sites were the following: cheek, labial, chewing-gingival and back of the tongue.

Stereolithography in oral implantology: a comparison of surgical guides.

This article presents the use of stereolithography in oral implantology. Stereolithography is a new technology that can produce physical models by selectively solidifying an ultraviolet-sensitive liquid resin using a laser beam, reproducing the true maxillary and mandibular anatomic dimensions. With these models, it is possible to fabricate surgical guides that can place the implants in vivo in the same places and same directions as those in the planned computer simulation.

Prevention of postoperative bleeding in anticoagulated patients undergoing oral surgery: use of platelet-rich plasma gel.

Purpose: This study evaluated the effectiveness of a protocol using platelet-rich plasma (PRP) to prevent bleeding after dental extraction in patients treated with anticoagulant oral therapy.

Materials And Methods: Forty patients with mechanical heart-value replacement who were treated with anticoagulant oral therapy were selected for the study. Each patient was treated with PRP gel placed into residual alveolar bone after extraction without heparin administration after suspension of oral anticoagulant drugs (36 hours).
