ABSTRACT

Osteomas são tumores de crescimento ósseo benigno, que se apresentam sob a forma periosteal ou endosteal e acometem comumente os ossos do esqueleto craniofacial, sendo raramente encontrados em outras partes do corpo. Quando presentes, frequentemente são encontrados na mandíbula, maxila, nos seios paranasais e no osso frontal. São neoplasias de crescimento lento, geralmente assintomáticas, que podem se desenvolver em osso esponjoso ou compacto. O osteoma periférico apresenta-se, geralmente, como um tumor solitário, unilateral, encontrado mais frequentemente no corpo da mandíbula. Neste artigo, é descrito um relato de caso de um osteoma periférico em uma paciente do sexo feminino, na oitava década de vida, sintomático, localizado em corpo mandibular, com 10 anos de evolução.


Osteomas are benign tumors of growing bone that present in a periosteal or endosteal form and commonly affect the craniofacial skeleton bones, being rarely found in other parts of the body. When present, they are often found in the mandible, maxilla, frontal bone and paranasal sinuses. They are slow-growing neoplasms, usually asymptomatic, which can develop in compact or cancellous bone. The peripheral osteoma usually presents as a solitary unilateral tumor, most often found in the body of the mandible. This paper presents a case report of a peripheral osteoma located in the mandibular body in a symptomatic female patient in her eighth decade of life with ten years of progression.

ABSTRACT

Introduction: Violence against women has become a public health problem, and the dentist is the main responsible for the treatment of their victims, since numerous cases with a high incidence of impaired maxillomandibular complex occurred. Objective: The aim of this study was to analyze the prevalence and evolution of jaw fractures in woman due to domestic violence. Material and methods: The medical files from the Hospital and Maternity of São José dos Pinhais/PR (HMSJP) was searched for female patients diagnosed with jaw fractures caused by trauma, considering the aggressor and the prevalence in the period from January 2001 to May 2003. Results: There were 23 women with jaw fractures, aged from 15 to 43 years. Nasal fractures were the most prevalent, followed by the zygomatic complex and mandible fractures. The husbands were the main responsible for the attacks. The fractures treated by reduction had satisfactory bone consolidation. Conclusion: Patients with jaw fractures had favorable bone consolidation after being submitted to surgical treatment. Nasal fractures were the most prevalent type and the husband was most responsible for the attacks.

ABSTRACT

Dentro do grupo dos pacientes pediátricos, as fraturas de ossos faciais no recém-nascido são pouco relatadas na literatura. É um acontecimento raro, quando ocorre no momento do parto. A mandíbula é o osso da face mais envolvido, sendo sua incidência aumentada com o passar da idade. O presente artigo relata um caso de fratura de mandíbula ocorrida no momento de um parto prematuro, tratada de forma conservadora, com acompanhamento pós-operatório de 5 anos.


Within the group of pediatric patients, facial bone fractures in the newborn are rarely reported in the literature. They are of rare occurrence at the time of delivery. The mandible is the facial bone most involved in fractures, the incidence of which tends to increase with age. This article reports a case of mandibular fracture that occurred at the time of premature obstetric labor, which was treated conservatively and followed up for 5 years.

ABSTRACT

O odontoma complexo é um tumor odontogênico misto, benigno, sendo composto por uma massa desordenada de tecidos dentários duros. O cisto dentígero de desenvolvimento é uma lesão revestida por uma cápsula de tecido epitelial odontogênico, caracterizada por seu envolvimento com dentes irrompidos e pelo acúmulo de líquido em seu interior. A associação entre lesões de origem odontogênica pode ser explicada pelo potencial de diferenciação do tecido epitelial durante a odontogênese. O diagnóstico é estabelecido por critérios clínicos e pela análise radiográfica, associado ao exame anatomopatológico. O presente artigo tem como objetivo apresentar dois relatos de caso de odontoma complexo associado a cisto dentígero, tratados com excisão cirúrgica simples do odontoma e enucleação do cisto dentígero. São discutidos pontos relacionados ao diagnóstico, ao tratamento e à origem de tais lesões.


Complex odontoma is a mixed benign odontogenic tumor, consisting of a disorganized mass of hard dental tissue. The developmental dentigerous cyst is a lesion lined by a capsule of odontogenic epithelial tissue, characterized by its involvement with an unerupted tooth and the accumulation of fluid within it. The association between lesions of odontogenic origin can be explained by the differentiation potential of epithelial tissue during odontogenesis. The diagnosis is established by clinical and radiographic analysis in association with the anatomopathological examination. The aim of this paper is to present two case reports of complex odontoma associated with a dentigerous cyst treated with the surgical excision of the odontoma and enucleation of the dentigerous cyst. Topics related to the diagnosis, treatment and origin of such lesions are discussed.

ABSTRACT

O tratamento das maxilas severamente reabsorvidas é um grande desafio para a Implantodontia atual. Quando se deseja a reabilitação de maxilas atróficas através de implantes osseointegrados, necessitamos utilizar enxertos ósseos autógenos de fonte extraoral, o que acarreta em maior morbidade pós-operatória, associada a um maior tempo de tratamento. O implante zigomático é uma alternativa viável, na reabilitação dos pacientes relutantes ao procedimento de reconstrução, através de enxertia óssea. Esse método de tratamento tem altas taxas de sucesso, aliadas a baixas taxas de complicações. Objetivamos, através deste relato de caso clínico, demonstrar uma complicação incomum (fístula extraoral causada pela exteriorização do ápice do implante no corpo do osso zigomático) e o seu respectivo tratamento.


Treatment of severely resorbed maxilla is a great challenge for current implant practice. When atrophic maxilla are rehabilitated by means of osseointegrated implants, extra-oral autogenous bone grafts are need resulting in increased postoperative morbidity and longer treatment periods. In such cases, the zygoma implant is a viable option for those avoiding reconstruction with bone grafts. This treatment method has high success rates, combined with low complication rates. The aim of this case report is to demonstrate an uncommon complication (extra-oral fistula caused by exteriorization of the implant apex of the implant into the body of the zygoma bone) and its treatment.

ABSTRACT

O câncer de boca é uma das neoplasias malignas mais freqüentes, sendo a região labial um dos sítios mais acometidos. O carcinoma epidermoide de lábio (CEL) acomete pessoas de pele clara e com pouca capacidade de bronzeamento, estando diretamente relacionado a exposição solar prolongada. Cerca 90% dos casos ocorrem no lábio inferior, sendo o lábio superior raramente acometido (7%). O presente artigo relata um caso raro de CEL em lábio superior em um paciente feoderma.


Oral cancer is one of most common malignant neoplasia worldwide, and the lip is the most frequent location. Lip squamous cell carcinoma is more common on fairy-skinned people with low tanning capacity, directly related to chronic sun exposure. Nearly 90% of cases occur in the lower lip, and the upper lips rarely committed (7%). Here, we report a rare case of squamous cell carcinoma of the upper lip in a brown-skinned pacient.
