ABSTRACT

INTRODUCCIÓN: La recesión gingival localizada es un problema de salud bucodental fundamental porque su progresión conduce a la pérdida dentaria. El propósito de este trabajo fue evaluar la influencia de distintos parámetros clínicos sobre la recesión gingival localizada. MATERIAL Y MÉTODOS: Se estudiaron 40 pacientes con recesión gingival localizada en los que se analizaron diversos parámetros clínicos relacionados con la recesión gingival. Para la comparación de variables cuantitativas se utilizó el test de Student (t-Student) y para la de variables cualitativas el test chi-cuadrado. RESULTADOS: En este estudio, según la clasificación de Miller, el 37,5% de los pacientes tenían recesiones de tipo I, el 60% de tipo II y el 2,5% restante, de tipo III. Los siguientes parámetros: edad, frecuencia de cepillado, tipo de cepillo, uso de colutorios y de seda dental, otros hábitos orales y el tratamiento de ortodoncia, no tienen influencia sobre la severidad de la recesión gingival (p > 0,05 en todos los casos). Presentan recesión gingival más severa, los varones (p = 0,03), los sujetos fumadores (p = 0,007) y los que tienen técnicas de cepillado horizontal (p = 0,02). En los cuatro momentos de seguimiento del estudio (inicial, 6, 12 y 18 meses), la profundidad de sondaje, la pérdida de inserción, el índice de placa y el índice de sangrado mejoraron a los 6 meses para luego empeorar en el resto de períodos. DISCUSIÓN: El sexo, el tabaco y la técnica de cepillado son los tres factores que tienen influencia sobre la severidad de la recesión gingival localizada en este estudio


INTRODUCTION: Localised gingival recession is a major problem of oral health because its progression leads to the dental loss. The aim of this study was to evaluate the possible influence of different clinical parameters in localised gingival recession. MATERIAL AND METHODS: Forty patients with localised gingival recession were studied. Data from several clinical parameters related to gingival recession were collected. RESULTS: In this study, 37.5% of patients had recessions of Miller's type I, 60% Miller's type II, and the remaining 2.5% of Miller's type III. Age, frequency of toothbrushing, toothbrushing technique, use of mouthwash and/or dental floss, other oral habits, and orthodontic therapy, have no influence on the severity of gingival recession (p > 0.05 in all cases). More severe gingival recession was observed in males (p = 0.03), smokers (p = 0.007) and those with horizontal toothbrushing techniques (p = 0.02). In the four follow-up periods of the study, probing depth, attachment loss, plaque index and bleeding index improved after 6 months and then got worse in the rest of the follow-up intervals. DISCUSSION: Gender, smoking and toothbrushing technique were the three factors that influenced the severity of localised gingival recession

ABSTRACT

Introducción: La recesión gingival localizada es un problema de salud bucodental fundamental porque su progresión conduce a la pérdida dentaria. Discusión: El criterio de actuación será controlar periodontalmente al paciente para asegurar un adecuado control de placa de las zonas más susceptibles a presentar la recesión (AU)


Introduction: The localized gingival recession is a fundamental problem of oral health because its progression leads to the dental loss. Discussion: The criterion of acting will be to control periodontally the patient to ensure an adequate plaque’s control of the areas that are more likely to develop the recession (AU)

ABSTRACT

Las lesiones periapicales resultado de la necrosis de la pulpa dental son las patologías que más frecuentemente ocurren encontradas en el hueso alveolar. El tratamiento consiste en la eliminación de los agentes infecciosos mediante el tratamiento del canal radicular, permitiendo la cicatrización de la lesión


Periapical lesions, which are a result of the necrosis of the dental pulp, are the most frequently occurring diseases found in the alveolar bone. The treatment involves the removal of infectious agents by treating the root canal, allowing the wound healing

ABSTRACT

The recovery of small elements of the skeleton (e.g. hyoid, carpals, and hand and foot phalanges) is one of the established tasks of the archaeologist and physical anthropologist when working in the field, whether in an archaeological or forensic context. In the present work, we illustrate the field location of ossified laryngeal cartilages, hand sesamoids, and the medial clavicular epiphyses. The potential information offered by these elements is briefly summarized. The frequency of these elements observed in a cemetery dating from 1943 indicates the possibility that these elements could be found in other contexts at a higher frequency than expected.

ABSTRACT

The use of reactive barriers is one of the preferred remediation technologies for the remediation of groundwater contamination. An adequate design of these barriers requires the understanding of the kinetics of the reaction between the target contaminant and the solid phase in the barrier. A study of the kinetics between metallic iron and aqueous nitrate is presented in this paper. Published literature regarding this reaction indicates that researchers are far from a consensus about the mechanism of this reaction. This paper presents the results obtained from experiments performed at different constant pH values and iron dosages, together with a mathematical analysis of the kinetic results. We have found that an Eley-Rideal kinetic model yields a good explanation of the relatively complicated dependence between rate of nitrate reduction and the pH value of the solution.
