ABSTRACT

La coloración rosa de los dientes puede originarse por diferentes factores. En el ámbito forense se ha descrito al fenómeno denominado post mortem pink teeth como un signo asociado a muertes violentas de etiología diversa. En la práctica clínica también es posible observar pacientes con dientes rosados, fre-cuentemente ocasionados por traumatismos o iatro-genia proveniente de ortodoncia, cuyo mecanismo de producción obedece a distintas etiopatogenias, destacándose las reabsorciones dentinarias inter-nas, cemento-dentinarias externas y calcificaciones dentinarias. El presente artículo expone el caso de un individuo adulto con antecedente de trauma óseo-dentario por accidente vial que, luego de un prolon-gado tiempo, asiste al Servicio de Urgencias Odon-tológicas y Orientación de Pacientes de la Facultad de Odontología de la Universidad de Buenos Aires, en donde se le detecta, a modo de hallazgo exploratorio, una ostensible coloración rosada en el canino infe-rior derecho. La situación motivó un pormenorizado abordaje clínico y radiográfico, indagando respecto a los probables factores que intervinieron en su ge-neración y desarrollo (AU)


The pink coloration of the teeth can be caused by dif-ferent factors. In the forensic field, the phenomenon called post mortem pink teeth has been described as a sign associated with violent deaths of various etiology. In clinical practice, it is also possible to ob-serve patients with pink teeth, frequently caused by trauma or iatrogenesis from orthodontics, whose production mechanism is due to different etiopatho-genesis, highlighting internal dentin resorption, ex-ternal cemento-dentinal resorption and dentin calci-fications. This article presents the case of an adult individual with a history of bone-dental trauma due to a road accident who, after a long time, attends the Dental Emergency and Patient Guidance Service of the Faculty of Dentistry of the University of Bue-nos Aires, where an ostensible pink coloration was detected in the lower right canine as an exploratory finding. The situation motivated a detailed clinical and radiographic approach, inquiring about the probable factors that intervened in its generation and development (AU)

ABSTRACT

This study evaluated the electromyographic characteristics of masticatory and neck muscles in subjects with vestibular lesions. Surface electromyography of the masseter, temporalis and sternocleidomastoid muscles was performed in 19 patients with Ménière's disease, 12 patients with an acute peripheral vestibular lesion, and 19 control subjects matched for sex and age. During maximum voluntary clenching, patients with peripheral vestibular lesions had the highest co-contraction of the sternocleidomastoid muscle (analysis of covariance, p=0.02), the control subjects had the smallest values, and the patients with Ménière's disease had intermediate values. The control subjects had larger standardized muscle activities than the other patient groups (p=0.001). In conclusion, during maximum voluntary tooth clenching, patients with vestibular alterations have both more active neck muscles, and less active masticatory muscles than normal controls. Results underline the importance of a more inclusive craniocervical assessment of patients with vestibular lesions.

ABSTRACT

Se intenta llamar la atención sobre un problema frecuente en odontología, que no suele estudiarse de modo sistemático: las causas, efectos y posibles soluciones de las pérdidas de sustancia dentaria que se extienden hasta la zona subgingival. Dado que la mayoría de los colegas pueden hallarse ante esta situación, se les pide también que comuniquen sus opiniones sobre ella y su experiencia en la materia

ABSTRACT

Estudo comparativo da distribuiçäo das tensöes internas em um dente natural e em dente endodonticamente tratado, pelo método do elemento finito em modelo bidimensional de segundo pré-molar inferior, sob carga axial de 30 kgf em três pontos (contato primário e estabilizante) e, processados pelo programa SAP90. Os resultados indicaram maior acúmulo de tensöes, na metade vestibular, no dente natural e no dente restaurado. As tensöes foram mais intensas sob o ponto de aplicaçäo de cargas, nos dois modelos. As tensöes foram maiores no dente restaurado, por causa do maior módulo de elasticidade dos materiais restauradores, demonstrando que existem diferenças na distribuiçäo das tensöes no dente e na base óssea nos dois modelos

ABSTRACT

A despeito da enorme importância das vitaminas e sais minerais no metabolismo celular dos tecidos e no correto desenvolvimento, crescimento e desempenho funcional dos órgäos, na manutençäo das funçöes vitais e resistência às infecçöes, pouca atençäo têm estes recebido no que diz respeito à sua influência na saúde bucal. A carência de vitaminas apresenta repercussöes na saúde bucal, na higidez da mucosa, língua e estruturas de suporte dos dentes, e mesmo os dentes podem sofrer a açäo dessa carência se sua ocorrência se verificar no estágio de desenvolvimento dentário
