RESUMO

BACKGROUND: Due to increased formaldehyde exposure, carcinogenic to humans, several researches have been studying the potential toxicity and the safe levels for human beings. The aim of this study was to investigate mutagenicity and cytotoxicity in buccal epithelial exfoliated cells (BEC) of students subjected to formaldehyde (FA) during anatomy classes. MATERIAL AND METHODS: BEC were collected periodically from 17 volunteers of undergraduate programs, who had participated in practical anatomy classes, before and after FA exposure. Cells were stained according to Feulgen method and then micronucleus test was applied. A total of 1,500 cells were assessed per individual in this study for the micronucleus frequency and other parameters of cytotoxicity. RESULTS: There was statistically significant increase in number of micronucleated BEC after FA exposure (after 1 month p=.034 and after 3.5 months p=.017). However, FA exposure caused no significant increase in other nuclear alterations closely related to cytotoxicity (p≥.05). CONCLUSIONS: FA induced mutagenicity during anatomy classes. Cell death increased, but it was not statistically significant. Efforts have to be made to improve air quality and reduce exposures during anatomy classes.

RESUMO

El quiste nasolabial es un raro quiste no odontogénico, su origen embriológico es poco claro. Son lesiones decrecimiento extraóseo, que se presentan como una tumefacción que eleva el ala nasal, indoloro, desplazable y fluctuante. Se localiza en la apófisis alveolar cercana a la base del ala de la nariz. El tratamiento consiste en la enucleación quirúrgica de la lesión. En este artículo se presenta un caso de quiste nasolabial, que acomete a una paciente de sexo femenino de 51 años de edad, de la cual se discuten los datos clínicos, aspectos diagnósticos, imagenológicos, histopatológicos, así como su tratamiento (AU)


The nasolabial cyst is a rare nonodontogenic cyst with its embryological origin little clear. They are extraosseous lesions with growth that appears like a swelling that lifts the nasal wing, painless, sliding and fluctuating. It is located in the alveolar apophysis near the base of the wing of the nose. The treatment consists of surgical enucleating of the lesion. This article presents a case of nasolabial cyst in a female patient of 46 years age, describing clinical, diagnostic, imaging, and histopathological aspects as well as the treatment employed (AU)

RESUMO

El fibroma osificante central (fibroma cementificante / fibroma cemento osificante) es un tumor benigno óseo bien delimitado, se localiza principalmente en los maxilares aunque se puede presentar en los huesos orbital, frontal, paranasal y temporal. Se caracteriza por presentar un crecimiento y una tumefacción deformante de evolución lenta con una incidencia mayor en la mandíbula. El tratamiento consiste en la extirpación quirúrgica de la lesión. En este artículo se presenta un caso de fibroma osificante central localizado en la región posterior derecha del maxilar superior, de gran dimensión, que acomete a una paciente de sexo femenino de 46 años de edad, revelando datos clínicos, aspectos diagnósticos, imagenológicos, histopatológicos así como su tratamiento (AU)


Central ossifying fibroma (cementing fibroma / cemento ossifying fibroma) is a bone benign tumor almost exclusively from maxillary region but can be in the orbital bones, frontal, paranasal and temporal. Progressive growth and disfiguring swelling of slow evolution are characteristics with more prevalence in the mandible. The treatment choice is a surgical excision of the lesion. This article presents a case of central ossifying fibroma located in the region of the right posterior maxilla of large dimension of a female patient of 46 years of age, describing clinical, diagnostic, imaging, and histopathological aspects as well as the treatment employed (AU)

RESUMO

Los dientes natales y neonatales son anomalías relativamente raras en los recién nacidos, que pueden causar trastornos en la alimentación, ulceraciones traumáticas sublinguales (enfermedad de Riga-Fede) y preocupaciones en cuanto a la aspiración de los mismos. La diferencia entre los dientes natales y neonatales está en el momento de la erupción. Los dientes natales son dientes que aparecen en la cavidad oral en el momento del nacimiento y los dientes neonatales son los que aparecen durante las primeras semanas de vida. El objetivo de este artículo es presentar a través de una revisión de la literatura, los aspectos más relevantes de los dientes neonatales y la presentación de un caso clínico de un recién nacido con pocos días de vida con diente neonatal, donde el tratamiento aplicado fue la extracción (AU)


Natal and neonatal teeth are rare anomalies in newborns that can cause feed disturbances, tongue ulceration(Riga-Fede disease) and risk of aspiration of them. The difference between natal and neonatal teeth is based on time of eruption. The natal teeth are those that are already present in the oral cavity since birth, and neonatal teeth are those that appear in the oral cavity in the first month of life. The aim of this paper is to present a case of neonatal tooth as well as to discuss, with literature basis, the most relevant aspects concerning the diagnosis and treatment employed (AU)

RESUMO

La Osteomielitis es una infección del tejido óseo que involucra a todas las estructuras del hueso provocada por microorganismos. El cuadro clínico se caracteriza generalmente por la presencia de fístula de drenaje, dolor intenso, inflamación, movilidad de los dientes involucrados en la zona afectada, fiebre y edema. El tratamiento consiste en medicamentoso y/o quirúrgico. En este artículo se presenta un caso de Osteomielitis crónica supurativa en el maxilar superior, que acomete a un paciente del sexo femenino de 82 años, en el cual se discuten los aspectos diagnósticos e histopatológicos como el tratamiento correspondiente del caso (AU)


Osteomyelitis is an infection of bone tissue that involves all structures of the bone caused by microorganisms. The clinical picture is generally characterized by the presence of fistula drainage, severe pain, swelling, mobility of teeth involved in the affected area, fever and edema. Treatment involves medication and / or surgery. This article presents a case of chronic suppurative osteomyelitis in the maxilar superior of a female 82 years old patient, as well as a discussion of clinical and histopathological aspects and the treatment employed (AU)
