RESUMO
BACKGROUND: A proportion of oral squamous cell carcinoma (OSCC) is preceded by oral potentially malignant disorders (OPMD), and the rest might not be associated with any well-established OPMD. Chronic traumatic ulcer (CTU) has been suggested as a lesion with potential for malignant transformation, but the evidence is inconclusive. OBJECTIVE: The aim of this study was to describe clinicopathological features of non-healing CTU (NHCTU) that later developed to OSCC. MATERIALS AND METHODS: A retrospective cohort study was performed of patients attending the Facultad de Odontología Universidad Nacional de Córdoba (2013-2019). The study included patients with a provisional diagnosis of CTU. CTUs without complete healing after removal of traumatic factors-non healing CTU (NHCTU)-were investigated by biopsy. A detailed description of cases where a malignancy was diagnosed is presented. RESULTS: A total of 107 CTU were included. Of these, 32 CTUs were considered NHCTU and two cases showed histological features of OSCC in the background of NHCTU. In both cases, lesions were found on the lateral tongue. Both were non smoking, non alcohol drinking individuals. Absence of any well-known OPMD was also registered. CONCLUSIONS: The possibility of malignant transformation in a subset of tongue NHCTU should not be underestimated. CLINICAL RELEVANCE: In a subgroup of patients, NHCTU could be considered an OPMD. Although the potential malignant transformation rate is low, these conditions should be always followed up.

Introdução: a Odontologia vem conquistando um espaço fundamental no ambiente hospitalar, especialmente nas Unidades de Terapia Intensiva (UTI), onde o cirurgião-dentista (CD) atua em diversas situações, sendo desde o diagnóstico de patologias bucais até os diversos procedimentos necessários para a saúde bucal e a manutenção da qualidade de vida do paciente. Dentre as complicações bucais que podem ocorrer em paciente desse perfil estão as lesões traumáticas, que quando presentes, requerem tratamento e acompanhamento odontológico. Objetivo: o presente caso ilustra a atuação do CD em uma UTI neurológica onde uma paciente em estadio avançado de câncer de mama apresentou uma úlcera traumática em lábio inferior requerendo planejamento preventivo e tratamento para a afecção. Método: trata-se de um relato de caso com método descritivo. Resultados e Discussão: a paciente seguiu acompanhada pela equipe de um Hospital privado que assistia aos pacientes uma vez ao dia, entretanto, quando ocorreu um novo trauma não havia um CD de plantão e a gravidade foi maior. Conclusão: diante disso, com este artigo enfatizamos a importância da presença integral de um CD na UTI com o intuito de minimizar as complicações bucais e proporcionar melhor qualidade de vida ao paciente.
Introduction: dentistry has been gaining a fundamental place in the hospital environment, especially in Intensive Care Units (ICUs), where the dental surgeon (CD) acts in several situations, ranging from the diagnosis of oral pathologies to the various procedures required for oral health And maintenance of the patient's quality of life. Among the oral complications that may occur in patients with this profile are traumatic lesions, which, when present, require dental treatment and follow-up. Objective: the present case illustrates the performance of CD in a neurological ICU where an advanced stage breast cancer patient presented a traumatic ulcer on the lower lip requiring preventive planning and treatment for the condition. Method: this is a case report with a descriptive method. Results and Discussion: the patient was followed by the staff of a private hospital who attended the patients once a day. However, when a new trauma occurred, there was not on-call CD and the severity was greater. Conclusion: therefore, with this article we emphasize the importance of the integral presence of a CD in the ICU in order to minimize oral complications and provide a better quality of life for the patient.

This is a report of a case of an unusual oral lesion after the placement of mini implants for the retention of a mandibular overdenture. A patient received four 2-mm-wide dental implants in the anterior mandible and had her mandibular denture relined with a soft material. After 3 months, she was not wearing her mandibular denture, and two nodular ulcerated lesions were observed near the mini implants. The lesions ceased following excision and regular denture wearing. Clinical and microscopic examination led to the diagnosis of traumatic ulcerative granuloma with stromal eosinophilia (TUGSE). TUGSE is rare lesion with a benign course that may occur following injury of the oral mucosa by mini implants under certain circumstances.
