    Prevention of Inflammatory Complications upon Surgeries in Maxillofacial Region
    (Journal of Diagnostics and Treatment of Oral and Maxillofacial Pathology, 2017-06-30) Tymofieiev, Oleksii; Ushko, Natalia; Tymofieiev, Oleksandr; Yarifa, Maria; Fesenko, Ievgen
    Conducting of prophylactic antibiotic therapy in patient after surgical interventions in oral and maxillofacial surgery reduces the incidence of postoperative infectious complications. The analysis of the clean, conditionally clean, dirty (potentially infected), and purulent surgeries is performed. The general questions of prophylaxis of infection complications in plastic, orthognathic, purulent surgeries, and oral microflora are considered. Consecutive cases of postoperative complications and purulent conditions at the head and neck areas are presented. Recommendations on the antibiotic prophylaxis in oral and maxillofacial surgery are given.

    Purpose: To determine the severity of potentiometric parameters in patients with malignant neoplasms of the oral mucosa and the presence of metal inclusions in the form of non-removable dentures made of dissimilar metals and their alloys. Methods: We examined of potentiometric parameters in 39 patients with metallic inclusions in the oral cavity, in which malignant tumors of the mucous membrane of the oral cavity (tongue, palate, mucous membrane of the alveolar process and the bottom of the oral cavity) were detected. All subjects were between the ages of 40 and 68 years. Results: High potentiometric indicators were revealed in patients with non-removable metal dentures, which are made of dissimilar metals and their alloys. The presence of defects in the lining of dentures, as well as metal parts of a non-removable structure or metal protective coating ("bald zones") increase the potentiometric parameters and increase the risk of malignant neoplasms of the mucous membranes. Conclusions: The presence of metal inclusions in the oral cavity in the form of permanent dentures can be one of the reasons for the development of malignant neoplasms of the mucous membranes. A significant increase (more than 3 times higher than the normal values) of potentiometric parameters in patients with malignant tumors of the mucous membranes with metallic inclusions in the oral cavity is observed not only between the metals of immovable dentures, but also between the metal denture and the mucosa of the alveolar process of the jaw, between different parts of the mucous membranes of the alveolar process.
