ABSTRACT
AIMS: Radiation caries (RC) is a highly prevalent and chronic complication of head and neck radiotherapy (HNRT) and presents a challenge for clinicians and patients. The present study aimed to assess the impact of RC on the morbidity and mortality outcomes of head and neck squamous cell carcinoma (HNSCC) patients. METHODS AND RESULTS: Patients were divided into three groups: (1) RC (n = 20), (2) control (n = 20), and (3) edentulous (n = 20). Information regarding the number of appointments, dental procedures, osteoradionecrosis (ORN), prescriptions, and hospital admissions were collected. Mortality outcomes were assessed through disease-free survival (DFS) and overall survival (OS) rates. RC patients required more dental appointments (p < .001), restorations (p < .001), extractions (p = .001), and antibiotic and analgesic prescriptions (p < .001). Kaplan-Meier subgroup analyses showed a significantly increased risk of ORN in RC compared to edentulous patients (p = .015). RC patients presented lower DFS rates (43.2 months) than the control and edentulous groups (55.4 and 56.1 months, respectively). CONCLUSIONS: RC impacts morbidity outcomes among cancer survivors due to increased demand for medication prescriptions, multiple specialized dental appointments, invasive surgical treatments, increased risk of ORN, and increased need for hospital admissions.

O objetivo do presente estudo foi relatar, por meio de um caso clínico, a reabilitação de uma paciente com uma prótese nasal implantorretida. A mesma possuía 68 anos de idade e foi encaminhada para a reabilitação nasal pela equipe que realizou a cirurgia oncológica de um tumor de pele na região do seu nariz. A paciente reportou queixa com relação à estética da face e problemas no convívio social. Foi proposta reabilitação com prótese nasal, com implantes osseointegráveis associados ao sistema de retenção por magnetos. Após cinco anos e dez meses, três novas próteses foram fabricadas devido a queixas da paciente em relação à descoloração da peça. Na última consulta, a prótese foi removida e inspecionada, e se constatou problemas na higienização, motivo das pigmentações escurecidas na superfície interna da peça e do exsudato no tecido mole ao redor dos pilares protéticos. Foram realizadas a limpeza da barra e do tecido mole, e a confecção de novas próteses nasais implantorretidas à base de silicone elastomérico, além de instrução sobre a necessidade de higienização. Constatou-se que próteses nasais implantorretidas à base de silicone elastomérico são eficientes e seguras para a reabilitação de defeitos na região do nariz. Além disso, é extremamente necessário que o profissional transmita aos pacientes a necessidade de uma higienização satisfatória, solicitando retornos periódicos para obter o máximo do desempenho clínico de suas próteses e implantes.
The aim of present study was to report the rehabilitation of a patient with magnet-retained nasal prosthesis. A 68-year-old female patient was referred to nasal rehabilitation by the surgical team that performed the removal of a skin nose tumor. The patient complained about her facial aesthetics and also reported fearing social interactions. The rehabilitation with nasal prosthesis associated with osseointegrated implants, and retained by magnets was proposed to the patient. After 5 years and 10 months, 3 new prostheses have been fabricated because the patient complained about their discoloration. In the last check-up, the prosthesis was removed and visual inspection revealed lack of hygiene maintenance, which resulted in dark pigments in the intaglio surface as well as exudate in the peri-implant soft skin. The prosthetic components and soft tissue were cleaned, the fabrication of new magnet-retained nasal prosthesis was performed and instructions about the necessity of oral hygiene were also transmitted. The implant-retained nasal prosthesis is an effi cient and safe method for the rehabilitation of defects in the nasal area. Furthermore, it is extremely necessary that clinicians advise patients to perform satisfactory hygiene maintenance and periodic controls in order to obtain long-term success in such cases.
