Abstract: Un diagnóstico correcto es la base para el tratamiento de todas las enfermedades. En caries, el enfoque general va dirigido a entender que sucede en el sitio de la destrucción. Sabemos que la caries se ha establecido antes que la superficie dentaria esté completamente cavitada. Por tanto, el tratamiento estará orientado al control de la infección y a la remineralización de la lesión inicial de caries a través del uso de preparados que contengan fluoruro, tales como, sal de mesa fluorurada, tabletas fluoruradas, dentífricos fluorurados, geles fluorurados, etc. A correct diagnosis is the basis for treatment of all diseases.

Abstract: The widespread use of fluoride has been fundamental in reducing the prevalence and severity of dental caries in the United States of America and in other developed countries. When used appropriately, fluoride is safe and effective in preventing and controlling dental caries. Today, nearly all the residents of the United States are in some measure exposed to fluoride, which can come from multiple sources. This document is based on a report prepared by a working group assembled by the Centers for Disease Control and Prevention of the United States. The report details recommendations on fluoride use to prevent and control caries in the United States, but some aspects of the report could also be valid for other countries. Frequent exposure to small amounts of fluoride on a daily basis is the best way to reduce the risk of caries in all age groups. Therefore, it is recommended that all people drink water with an optimal fluoride concentration and that they brush their teeth twice a day with a fluoride toothpaste. Individuals with a high risk of caries may need additional fluoride sources. These recommendations attempt to provide dentists and other health professionals, public health professionals, and the general public with guidelines for fluoride use so that there is maximum protection against caries but without increasing the risk of enamel fluorosis, and with an efficient use of available resources. The recommendations are divided into four major groups: 1) public health and clinical practice, 2) self-care or individuals, 3) consumer-product industries and professional health care organizations and public health agencies, and 4) new research. Adopting these recommendations could reduce even further the prevalence of dental caries in the United States and save both public and private resources.

Abstract: Se establecieron las características más sobresalientes de la lipoproteína (a), así como los mecanismos patogénicos de esta partícula lipoproteínica relacionados con la aterotrombogénesis. La lipoproteína (a) [Lp (a)], descubierta por Kare Berg en 1963, posee una composición similar a la de la lipoproteína de baja densidad (LDL). En su estructura también presenta a la apolipoproteína (a) [apo (a)], la cual está unida a la apo B100 mediante un enlace disulfuro. El aspecto más interesante de la biología de la Lp (a) lo constituye, sin dudas, la sorprendente homología estructural que existe entre el plasminógeno y la apo (a); esta apolipoproteína, además, es la responsable de las propiedades metabólicas y bioquímicas de la lipoproteína (a). Por su estructura peculiar y la correlación existente entre los niveles elevados de la Lp (a) y el desarrollo de complicaciones aterotrombóticas, esta lipoproteína se ha convertido en el objeto de numerosas investigaciones. The most outstanding characteristics of lipoprotein (a) as well as the pathogenic mechansism of this lipoproteinic particle related to atherothrombogenesis are established. Liopoprotein (a) [Lp (a)] discovered by Kare Berg, in 1963, has a similar composition to that of low density lipoprotein (LDL). In its structure it also presents apolipoprotein (a) [apo (a)], which is bound to apo B100 by a disulfur bond. The most interesting aspect of the biology of Lp (a) is undoubtedly the surprising structural homology existing between plasminogen and apo (a). This apolipoprotein is also the responsible for the metabolic and biochemical properties of lipoprotein (a). Due to its peculiar structure and to the correlation existing between the elevated levels of Lp (a) and the development of atherothrombotic complications, this lipoprotein has become the object of numerous researches.

Abstract: Introducción: las concentraciones altas de fluoruros en aguas de consumo pueden provocar efectos adversos a la salud; sin embargo, las concentraciones óptimas ejercen una acción protectora ante las caries dentales. Objetivos: describir la distribución espacial de las concentraciones de fluoruros en aguas de fuentes de abasto subterráneas de cuatro provincias del país, sus posibles variaciones estacionales y asociaciones con algunos elementos químicos. Métodos: se realizaron determinaciones de fluoruros y otros compuestos químicos en fuentes de abasto subterráneas públicas en ambas épocas del a o, y el análisis de la correlación con otros compuestos químicos. Para el análisis estadístico se utilizó el programa SPSS y para el análisis espacial se empleó el Sistema de Información Geográfica MapInfo Professional. Resultados: se realizaron mapas de la distribución espacial de las concentraciones de fluoruros a nivel de localidades y municipios, y se identificaron 16 localidades con concentraciones de fluoruros superiores a 0,7 mg/L en al menos una de las dos determinaciones realizadas; las concentraciones de fluoruros revelaron diferencias significativas en lluvia y seca, y mostraron correlaciones con la temperatura, la dureza total, los cloruros, el calcio y el sodio. Conclusiones: En la gran mayoría de las fuentes los valores medios de las concentraciones de fluoruros fueron evaluados como bajos, lo que apoya la pertinencia de mantener el Programa de Fluoruración de la Sal de Consumo en Cuba. Por otra parte, el hallazgo de concentraciones de fluoruros consideradas altas en algunas fuentes aisladas, fundamentan la necesidad de incorporar el monitoreo de las concentraciones de fluoruros en el Sistema de Vigilancia de Calidad del Agua de Consumo. ntroduction: high concentrations of fluoride in drinking water can cause adverse health effects, however, optimal concentrations exert a protective effect against dental caries. Objective: to describe the spatial distribution of the concentrations of fluoride in water supply from underground sources of four provinces, possible seasonal variations and associations with some chemical elements. Methods: we measured fluoride and other chemicals in public groundwater supply sources in both seasons, analyzing the correlation with other chemical compounds. Statistical analysis was performed using SPSS for spatial analysis and was used GIS MapInfo Professional. Results: there were maps of the spatial distribution of fluoride concentrations at the level of towns and municipalities, identified 16 locations with fluoride levels

Abstract: Aguascalientes presenta contenido de fluoruros superior a 1.5 mg/L. A pesar de que existe una exposición crónica a los fluoruros a través del agua para consumo humano en este estado, se han realizado pocos estudios para establecer los da os en la salud pública ocasionados por la ingesta de fluoruros. El objetivo de este trabajo fue establecer las prevalencias de fluorosis y caries dental en 445 ni os con una edad entre 9 y 11 a os que residían en diferentes zonas de exposición a fluoruros del estado de Aguascalientes. Se encontraron prevalencias de fluorosis dental cercanas al 100 % en aquellas regiones donde el agua para consumo presentó concentración de fluoruros superior a 5.0 mg/L. Inclusive en las zonas donde el contenido de fluoruros en el agua para consumo era inferior a 1.5 mg/L, las prevalencias de fluorosis dental fueron superiores al 50 %. Se encontró que el 76 % de los ni os que participaron en este estudio presentaron caries dental. Los resultados obtenidos en este estudio confirman la presencia de un problema de salud pública de fluorosis dental en esta entidad mexicana.

Abstract: Desde finales del siglo XIX se reportan los primeros casos con dientes negros o esmalte moteado , pero no es hasta las décadas del 30 y 40 del siglo XX que se asocian a la presencia de flúor en el agua y a su vez a la menor prevalencia de caries en la población, por lo que se recomienda en los a os 50 por la OMS, la utilización de los fluoruros para prevenir la caries dental. Se expone información referente al desarrollo histórico que ha tenido la fluoruración del agua y de la sal en el mundo y en Cuba, así como las principales formas de utilización de los fluoruros para prevenir la caries de Since the end of the XIX century the first cases of black tooth or mottled enamel were reported , but it is not until the 30’s and 40’s of the XX century that they are associated with the presence of fluorine in water and with the lower prevalence of caries in the population. That’s why in the 50’s the WHO recommended the use of fluorides to prevent dental caries. Information referring to the historical development of the fluoridation of water and salt in the world and in Cuba, and about the main forms of utilization of fluorides to prevent dental caries is given
