Hoy en día la realización de una adecuada lactancia materna en la población está disminuyendo, esto gracias al modernismo y el mundo globalizado en que viven las mujeres de hoy en día. Se presenta a continuación un estudio de tipo experimental que tuvo como objetivo demostrar la influencia positiva de la lactancia materna en el crecimiento cráneo - maxilar en cobayos recién nacidos. La población estuvo compuesta por 40 cobayos recién nacidos de la misma especie, edad y sexo, los cuales fueron asignados aleatoriamente en 2 grupos: GRUPO I: Grupo control, 20 cobayos que sirvieron como grupo control, los cuales lactaron normalmente. GRUPO II: Grupo experimental, 20 cobayos a los cuales se les aisló de sus madres evitándoles la lactancia materna. A los 21 días los cobayos fueron sacrificados con éter y luego decapitados. Se realizaron mediciones directas en cráneos y en trazad...

We report the rehabilitation of a total edentulous patient with cleft palate. Being a complex case involving one of the factors of stability (retention), we had to use materials with grater hydrophilicity to take impressions. The technique without pressure was used for primary impressions and technique of selective pressure (elastomer) for making the final impression; obtaining more intimate contact between the prosthesis and the mucosa, for better adhesion and cohesion. Completely relieved cuvettes were used to take impressions with a minimal pressure. The purpose of this treatment was to rehabilitate the masticatory system of total edentulous patient with cleft palate, unlike ordinary cases, the adaptation of the prosthesis to the mucosa should be intimate; maintaining the resilience of the mucosa and allowing good retention.

Reportamos la rehabilitación de un paciente edentulo total que presenta paladar hendido. Por tratarse de un caso complejo que afecta a uno de los factores de la estabilidad (retención), se tuvo que utilizar materiales de mayor hidrofilicidad para tomar las impresiones. Se usó la técnica sin presión para la impresión primaria y la técnica de presión selectiva (elastómero) para la toma de la impresión definitiva; obteniendo así mayor intimidad de contacto entre la prótesis y la mucosa, para mejor adhesión y cohesión. Se utilizaron cubetas completamente aliviadas para que la presión del material de impresión sea mínima. El propósito de este tratamiento fue rehabilitar el sistema masticatorio del paciente edentulo total con paladar hendido, que a diferencia de los casos comunes, la adaptación de la prótesis a la mucosa debe ser íntima; manteniendo la resilencia de la muc...

The purpose of this study was to determine the injuries that occur in soft tissue support in patients carrying total denture attended at dental clinic of San Marcos University in 2012. There were 40 evaluated patients between 53 and 86 years old, previous calibration. In order to determine the changes into the mucosa of support, all patients underwent a cytological smear. Each sample was stained with the Papanicolaou technique and performed with Bethesda system. The results indicated that 95 % had mucosal lesions, of which 10 % had dysplasia cells, 7.5% leukoplakia stomatitis 55 %, 17.5 % hyperplasia, 5 % ulcer. The 90 % of the prostheses presented instability. No significant difference was observed in the different occlusal schemes. Therefore, we concluded that the majority of patients with unstable prosthesis have developed sub-prosthetic injuries; therefore we emphasize that the prost...

Now we have various materials to for direct restorations in the previous sector. In this case the direct resin was used Beautiful II, which is a nanohybrid compound with optical characteristics of natural teeth. Likewise for indirect restorations exists materials which reproduce the optical characteristics similar to the dental tissues, in this case indirect laboratory resin Ceramage was used, which is a zirconium silicate that combine the advantages of ceramic and resin. In the present clinic case it’s detailed the protocol of the application of the resin Beautiful II and Ceramage. Results: the result high patient expectations because it was possible to restore the teeth involved restoring function loss and especially aesthetics in a suitable manner biomimicking both materials. Conclusions: deep knowledge of both materials to be used as well as the protocols and techniques to follow, ...

This investigation evaluates the clotting effect of extracts of two varieties of coca leaves: Erytrhoxylum coca var. Coca and novogranatense Erytrhoxylum var. Truxillense. The aim of the study was to determine the shortest time of clotting of the blood samples of the albin rats. 34 males and female rats were selected to have 3 ml. of blood of each one. The blood samples were distributed in three probes containing: 0,06 ml. of physiological serum (control group), 0,06 ml. extract of E. coca lam var. coca (coca group), and 0,06 ml. of extract E. novogranatense var. truxillense (truxillense group). The clotting time for the control group was of 1,42 (±0.31) min, coca group: 1,38 (±0.26) min, truxillense group 1,83 (±0.55) min. The Anova analysis of the results showed significant differences between groups (p<0.01). The coca group showed the shortest clotting time of all groups. The tr...

En la presente investigación se evaluó el efecto coagulante de los extractos de dos variedades de hoja de coca: Erytrhoxylum coca lam var. Coca y Erytrhoxylum novogranatense var. Truxillense. El objetivo fue determinar el menor tiempo de coagulación de muestras de sangre de ratas albinas, tratadas con los extractos. Se seleccionó una muestra de 34 ratas, machos y hembras, a las cuales se le extrajeron 3 ml de sangre a cada una, colocando 1ml de sangre en tubos que contenían 0.06 ml de suero fisiológico (grupo control), 0.06 ml de extracto de E. coca lam var. Coca (grupo coca), y 0.06 ml de extracto E. novogranatense var. Truxillense (grupo truxillense). Los tiempos de coagulación de las muestras del grupo control fue de 1.42 min (±0.31), el grupo coca obtuvo 1.38 min (±0.26) y el grupo truxillense 1.83 min (±0.55). Los promedios fueron comparados con Anova obteniendo diferencia...
