Restauração do dente tratado endodônticamente em pacientes com câncer de cabeça e pescoço

Abstract

Cancer is currently treated as a public health problem by the World Health Organization (WHO), with more than 20 million new cases estimated by 2025 worldwide, with most of them being located at developing countries. It is known that the treatment for such neoplasias can be several, but the most used are radiotherapy, chemotherapy and surgery. Several complications may arise from radiotherapy in the head and neck, such as mucositis, dysphalgia, trismus, ulcers, hyposalivation and changes in the dental structure and in materials used for coronary restoration, which it can directly influence the maintenance of the buccal element in the oral cavity. Endodontic treatment is indicated for the maintenance of the element and elimination of the infection focus and, when well planned and executed, gives full conditions for the maintenance of the dental element. The objective of this study was to evaluate the clinical condition and alterations in the restoration of the endodontically treated elements in patients with head and / or neck cancer who underwent radiotherapy. Fifteen patients were analyzed, obtaining a total of 39 teeth endodontically treated, where it was possible to observe a greater amount of resin as a final restorative material, but with a higher incidence of infiltrations and need of exchange when compared to the amalgam. Cement Ionomer of Glass (CIV) was the material that most presented property changes. The results found here do not contraindicate the use of adhesive materials for the restoration of the elements, but alert to the need of a reflection to when the odontologic intervention can be performed.
