Síndrome de Morquio, enfermedad de interés para la odontopediatría: presentación de un caso / Morquio syndrome, a disease of interest for pediatric dentistry: case report

El Síndrome de Morquio es un trastorno de almacenamiento de mucopolisacáridos se caracteriza principalmente por estatura corta y afectación ósea grave, pero el coeficiente intelectual es normal. La prevalencia es rara se estima que afecta a uno de cada 200.000 nacimientos hombres y mujeres por igual. La MPS IV A y B son enfermedades autosómicas recesivas con esto queremos decir que ambos progenitores son portadores del mismo gen afectado el cual se encuentra alterado produciendo así una deficiencia en la producción de la enzima. Las manifestaciones esqueléticas en esta displasia son retardo en el crecimiento, hipoplasia del odontoides, cifosis toracolumbar, displasia de cadera, genu valgo, manchas cutáneas y laxitud articular, en cuando a cuestiones dentales tenemos: el esmalte es delgado, rugoso e hipoplásico afectando dientes deciduos como permanentes. Se presenta el caso de un paciente masculino de 8 años 3/12 presentando MPS el cual requiere un protocolo de rehabilitación lo cual se realiza en el área de odontopedriatría del Hospital del Niño DIF.

Morquio syndrome is a mucopolysaccharide storage disorder is mainly characterized by short stature, severe bone involvement, but IQ is normal. The prevalence is rare is estimated to affect one in every 200,000 births men and women alike. The MPS IV A and B are autosomal recessive diseases with this we mean that both parents are carriers of the same gene affected which is altered thus producing a deficiency in the production of the enzyme. The skeletal manifestations in this dysplasia are growth retardation, hypoplasia of the odontoid, thoracolumbar kyphosis, hip dysplasia, genu valgus, skin blemishes and joint laxity, then dental issues are: the enamel is thin rugged and hypoplastic affecting deciduous theeth as permanent. The case of a male patient presenting eight years 3/12 MPS which requires a rehabilitation protocol which is done in the dental area of Hospital del Niño DIF is presented.

Diagnóstico diferencial de imagem sugestiva de lesão periapical / Diagnóstico diferencial de imagen sugestiva de lesión periapical / Differential diagnosis of periapical lesion suggestive image

Introdução: o conhecimento da anatomia radiográfica na área odontológica é muito importante para ajudar a estabelecer um diagnóstico correto, na diferenciação entre lesões ósseas e estruturas anatômicas. Objetivo: apresentar uma situação que demonstra confusão no diagnóstico entre o forame mental e lesões periapicais. Dados principais do caso: paciente que se queixava de dente escurecido, assintomático dois anos após um tratamento endodôntico. Na radiografia foi observada radioluscência no ápice do primeiro dente bicúspide inferior esquerdo, o que levou à suspeita de lesão periapical. Foram realizadas mais duas radiografias (mesializando e distalizando da região) observando-se o desligamento da área radiolúcida e um ligamento periodontal sem espaços. Principais comentários: a importância da compreensão da localização forame mentual está relacionada com o diagnóstico diferencial de lesões periapicais(AU)

Introducción: el conocimiento de la anatomía radiográfica en el área odontológica es muy importante para ayudar a establecer un diagnóstico correcto, y poder diferenciar las lesiones óseas de las estructuras anatómicas. Objetivo: presentar una situación que demuestra confusión en el diagnóstico entre el foramen mentoniano y lesiones periapicales. Datos principales del caso: paciente que se quejaba de diente que se oscureció, asintomático, dos años después de un tratamiento endodóntico. En la radiografía se observó radiotransparencia en el ápice de la primera bicúspide inferior izquierda, lo que llevó a la sospecha de lesión periapical. Se indicaron dos radiografías (mesializando y distalizando la región) y se observó la eliminación de la imagen radiolúcida y un ligamento periodontal sin espacios. Principales comentarios: Hay que tener en cuenta la ubicación del agujero mentoniano al realizar el diagnóstico diferencial con lesiones periapicales(AU)

Introduction: the knowledge of radiographic anatomy in the dental field is very important to subsidiary to establish of a correct diagnosis, in differentiation between bone lesions and anatomical structures. Objective: to present a situation that demonstrates confusion at diagnosis between the mental foramen and periapical lesions. Main data of the case: patient who complained of tooth darkened, asymptomatic two years after an endodontic treatment. Radiography was observed radiolucency at the apex of the first bicuspid tooth left lower, which led to suspicion of periapical lesion. There were over two radiographs (mesialing and distalizing the region) and observed the separation of radiolucent and a periodontal ligament without spacing. Main comments: The importance of understanding the location of the mental foramen is related to the differential diagnosis of periapical lesions(AU)

Cone beam computed tomography and intraoral radiography for diagnosis of dental abnormalities in dogs and cats

The development of veterinary dentistry has substantially improved the ability to diagnose canine and feline dental abnormalities. Consequently, examinations previously performed only on humans are now available for small animals, thus improving the diagnostic quality. This has increased the need for technical qualification of veterinary professionals and increased technological investments. This study evaluated the use of cone beam computed tomography and intraoral radiography as complementary exams for diagnosing dental abnormalities in dogs and cats. Cone beam computed tomography was provided faster image acquisition with high image quality, was associated with low ionizing radiation levels, enabled image editing, and reduced the exam duration. Our results showed that radiography was an effective method for dental radiographic examination with low cost and fast execution times, and can be performed during surgical procedures.

Clinical and radiological evaluation of zinc oxide-eugenol and Maisto's paste as obturating materials in infected primary teeth--nine months study.

The present study, performed in-vivo, included 30 infected primary teeth in 26 children in the age group of 3-8 years. The purpose of this study was to compare the efficacy of two obturating materials, zinc oxide-eugenol and Maisto's paste, in infected primary teeth. 30 teeth were divided into two groups of 15 teeth. Teeth in Group I were obturated using zinc oxide-eugenol and those in Group II were obturated using Maisto's paste. On clinical evaluation, teeth obturated with Maisto's paste showed 100% success. Five teeth that were overfilled with Maisto's paste showed complete resorption of excess material within 3 months while the two teeth overfilled with zinc oxide-eugenol showed incomplete resorption of the excess material even after 9 months. Zinc oxide-eugenol treated cases showed only 26.7% bone regeneration while in case of Maisto's paste, it was 93%. Complete healing of the inter-radicular pathology was seen with Maisto's paste. However, the pathology was present in 40% of the zinc oxide-eugenol treated teeth even after 9 months. Maisto's paste was thus seen to be superior to zinc oxide-eugenol both in clinical as well as radiological evaluation, done over a period of 9 months in relation to bone regeneration, healing of inter-radicular pathology and resorption of excess material.
