RESUMOO fibro-odontoma ameloblástico é um tumor odontogênico misto benigno, assintomático e raro, que pode ser facilmente confundido radiograficamente e histopatologicamente com outras enfermidades. Normalmente atinge uma população entre a primeira e a segunda décadas de vida, sendo mais frequente em mandíbula e com predileção pelo sexo masculino. Este tumor caracteriza-se pela agenesia dentária no local do tumor, sem predileção por região anatômica, e por um aumento de volume intrabucal, podendo causar leve assimetria facial. Apresenta crescimento lento, porém expansivo; revela-se como uma lesão radiolúcida bem definida, normalmente unilocular, com radiopacidades no seu interior. Normalmente a remoção cirúrgica é conservadora e o prognóstico é favorável. O presente trabalho relata um caso clínico de fibro-odontoma ameloblástico tratado por meio de remoção cirúrgica e com acompanhamento de dois anos. O objetivo deste trabalho foi estudar o fibro-odontoma ameloblástico em sua integralidade, buscando expor ao cirurgião-dentista os melhores métodos de diagnóstico e tratamento para tal lesão.Termos de indexação: Diagnóstico.

Lichen planus (LP) is a relatively common mucocutaneous disease with autoimmune etiology. Considering its malignancy potential, it is important to define the correct diagnosis, treatment, and clinical follow-up for patients with LP so that the disease is not diagnosed late, thus hindering the chances of curing the disease. This study aims to describe a clinical case of oral squamous cell carcinoma, potentially originated from LP. The patient is undergoing clinical and histopathological follow-up. A 64-year-old Caucasian male patient presented with a proliferative verrucous lesion on the tongue and sought treatment at the School of Dentistry, University of Passo Fundo (UPF), Passo Fundo, Brazil. He claimed the lesion had been present since 1988, and had been initially diagnoses as “oral lichen planus.” The physical exam presented three diagnostic hypotheses: plaque-like oral LP, verrucous carcinoma, and squamous cell carcinoma. After incisional biopsy and histopathological analysis, squamous cell carcinoma was diagnosed, probably originating from oral LP. The case study shows that malignancy from oral LP is possible, which justifies periodic clinical and histopathological follow-up, as well as the elimination of risk factors for carcinoma in patients with oral LP.
In Dentistry, any user with one or more limitations, of temporary or permanent mental nature, of physical, sensory, emotional or medical growth, is considered to be a Patient with Special Needs, preventing him from being subjected to a conventional dental situation. These patients form a group which may be considered at high risk for the development of oral diseases, according to the kind of pathogen. Among them, is the Williams-Beuren Syndrome, a rare congenital disease with cardiovascular involvement, mental retardation, dysmorphic face, idiopathic hypercalcemia, musculoskeletal problems, dental and growth anomalies. Familial and sporadic cases are thought to result from deletion of genetic material from adjacent genes located on the long arm of chromosome 7. This article reports a clinical case involving a four-year-old boy with Williams-Beuren Syndrome, referred to the clinic of the Specialization Course for Patients with Special Needs, at the São Leopoldo Mandic Dental Research Center, Campinas (SP). As the patient was resistant to dental care, in order to reduce anxiety and increase collaboration in clinical sessions, the Hixizine® medication was administered. For atraumatic restorative treatment and restorations, the following materials were used: Cleanjoy®, Futurabond DC®, Ionofil Plus® Grandioso®, Grandio® and Profluorid®. As result, it was possible to reach a level of excellence using the indicated materials and specific protocols. Based on this work and the lived experience, it can be observed that these patients can receive welcoming dental care in specialized clinics.
Over dentures are removable prostheses with additional retention mechanisms on either the roots of remaining teeth or implants and provide improved stability and retention. This study the paper is not a study but a case report on the use of bar-clip overdentures. Aimed: The purpose of this paper is to describe a prosthetic clinical protocol for treating the edentulous with a mandibular mucosal-supported and implant-retained bar-clip overdenture. In the presented case, the patient had functional and aesthetic problems with her current conventional dentures. Three osseointegrated implants were first successfully placed in the anterior mandible between the mental foramens. After the osseointegration period, customized molding procedures Case Study
