A comparison of mesio-distal crown dimensions of the permanent teeth in subjects with and without fluorosis

The pathogenesis of malocclusions, which are common among the population of all countries, is well represented in the professional literature. The occurrence of malocclusions is associated with genetic and various environmental factors. Among the latter, fluorides which affect the prevalence of some dental diseases are of particular interest. However, there are few publications reflecting the frequency of malocclusion among the population in the regions with different levels of fluoride in drinking water. This problem seems to be significant in the context of the increasing impact of fluorine compounds on human health, including dental health.The aim of the study. To analyze the literature on the frequency of malocclusion among the population living in conditions of variable fluoride content in drinking water. A manual search of domestic and foreign literature was performed in the search databases PubMed, Medline and Google Scholar. From the initial list of publications, eighteen articles that met the inclusion criteria for the study were selected for analysis. We revealed significant variability of the research results. Some authors note a higher prevalence of malocclusions among the population under conditions of increased fluoride intake, others note a lower one, and still others did not reveal any differences between the values obtained in both samples. Most of the assessed publications did not methodologically meet modern international standards, and therefore were of little evidence.The literature data do not provide grounds for an unambiguous assessment of fluorine compounds as an environmental factor that indirectly affects the process of occlusion formation in humans and animals.The review did not allow to make a definitive conclusion on the possible impact of systemic fluorides on the prevalence and pattern of malocclusion in humans and animals. It requires the implementation of studies that comply with the principles of evidence-based medicine.

Introducción:La fluorosis dental es una hipomineralización delesmalte producida como respuesta a la ingesta deflúor por un período prolongado durante la formacióndel esmalte.Es una alteración irreversible, que clínicamentese caracteriza por la presencia de delgadas líneasblanquecinas distribuidas en el esmalte dentalcorrespondientes a la disposición de las periquimatías,y en grados más avanzados de la enfermedad seobservan cambios en toda la superficie del esmalte,que adquiere un aspecto opaco, como de piedracaliza.En los niveles más severos de fluorosis dental, lapresencia de hipomineralización, y el aumento en laporosidad del esmalte dental propicia la pérdida deporciones importantes de su estructura, produciendofracturas, por lo que se deteriora la apariencia yfuncionalidad de los dientes afectados. La OMSrecomienda que el valor de referencia para el fluoruroen el agua potable es de 1,5 mg / l. El flúor esun gas halógeno, el más electronegativo de loselementos de la tabla periódica, con número atómico19, prácticamente no existe libre en la naturaleza, sinoasociado a otros elementos como: calcio y sodio.La principal vía de incorporación del flúor en elorganismo humano es la digestiva. Es absorbidorápidamente en la mucosa del intestino delgado y delestómago, por un simple fenómeno de difusión. Unavez absorbido, el flúor pasa a la sangre y se distribuyeen los tejidos, depositándose preferentemente enlos tejidos duros; se elimina por todas las vías deexcreción, principalmente por orina. Objetivo:saber diferenciar los tipos de materialesy conocer los diferentes métodos paraeliminación de flúor así como mostrar ladiferencia entre tratamientos. Metodología:El tipo de estudio es explicativo y conel cual se espera contribuir al desarrollodel conocimiento científico.Su realización supone el ánimo decontribuir al desarrollo del sabercientífico. Consistió en seleccionar 16pacientes, masculinos y femenonos yde distintas edades de entre 15 y 40años. Se dividieron al azar, en 2 gruposde 8 personas cada uno para tratarloscon 2 productos diferentes. El primergrupo fue tratado con ácido clorhídricoal 18% y el segundo grupo con la marcacomercial Antivet. Resultado y conclusión:La fluorosis dental es causada poringestas excesivas de flúor. El usodel ácido clorhídrico es corrosivo, suaroma es penetrante y los cuidadoscon el paciente son mayores, ya queun mal uso al tener contacto con piel omucosa creará necrosis. El Antivet tienedesventajas de costo y disponibilidad,pero su ventaja es que brinda másseguridad en su manipulación.
