The dental microabrasion treatment is an effective and conservative procedure against enamel surface defects. The white spots appear frequently in children because inactive enamel caries, hypoplasia and fluorosis. When these spots affect anterior teeth produce an aesthetic effect. We describe two cases of enamel microabrasion of the upper incisors for both cases using 37 % H3PO4 and a mechanical technique (micromotor) in a 7 year old child with enamel hypoplasia and a 7 year old boy with inactive enamel caries. The aim of study was to compare affectivity of enamel microabrasion with 37% H3PO4 and pumice using different gadgets for this mechanical technique. After the first microabrasion session, the best result was the one using resin polishing burs and home made acrylic pads respect to the group which use rubber points, but these differences did not longer appeared in the afterward sess...

La microabrasión dental es un procedimiento efectivo y conservador frente a los defectos superficiales del esmalte. Las manchas blancas del esmalte dental, aparecen frecuentemente en los niños por caries de esmalte inactiva, hipoplasias y fluorosis. Cuando estas manchas afectan a los dientes anteriores producen un efecto antiestético. Se describe dos casos clínicos de microabrasión del esmalte utilizando H3PO4 al 37 % y piedra pómez, mediante una técnica mecánica (micromotor), en un niño de 7 años con diagnóstico de hipoplasia del esmalte y otro niño de 7 años con diagnostico de caries de esmalte inactivo, en ambos casos la manchas blancas fueron localizados en el sector anterosuperior.

a Organización Mundial de la Salud (OMS), recomienda a las poblaciones con alta prevalencia de caries dental, la aplicación de agentes fluorados más el uso de antimicrobianos (ambos agentes quimioterapéuticos), especialmente en los pacientes con alto riesgo estomatológico junto con el uso de pastas dentales fluoradas, medida preventiva más empleada en el mundo y siendo la aplicación tópica de barnices, la presentación recomendada para devolver la salud bucal en menor tiempo, cuando la enfermedad ya está instalada (1-4) (13). Entre los agentes antimicrobianos más representativos, tenemos al Triclosán y la Clorhexidina, demostrando ésta última tener mayor efecto antiplaca (48), además de tener efectividad en el control y reducción de los niveles de streptococcus mutans y aparición de nuevas lesiones (18-21). Varios estudios aprueban la asociación de los barnices de Clorhe...

This article reviews the different reactions of the dental pulp before the injuries caused by dental caries and by the different restoration treatments performed on it. Therefore, it was concluded that the main objective is to provide the general practice dentist with the pertinent knowledge to orient, prevent and maintain the dental pulp health.

This article reviews main publications about Mineral Trioxide Aggregate (MTA) for its use and application in dental pulp treatments for young permanent teeth (immature apices) such as apexification. First, MTA cement was used to resolve a complication of root perforations, as well as retrograde fillings. Besides, it has features that differentiate it from Portland cement. For choosing treatment for pulpa1 injury in non-vital and vital teeth, we review root formation process from embryological point of view, different stages of root and apical development the immature tooth, comparing them to Nolla's 'stage classification of calcification. Therefore, apexification is a widely used altemative treatment for non-vital pulp, being calcium hydroxide and MTA materials the most common election.Afterwards, when there is formation of new tissue fpr apical closure, conventional root canal treatrnen...
