ABSTRACT

Los logros de los avances obtenidos en el manejo actual de la caries han dado la oportunidad a los odontólogos de detectar lesiones de caries en sus estadios incipientes. A pesar de la existencia de una gran variedad de materiales restauradores directos disponibles en el mercado actual y que pueden utilizarse para restaurar lesiones pequeñas de caries, el material que tiene más posibilidades de éxito para este tipo de lesiones es sin duda alguna el oro cohesivo, también conocido como oro directo (AU)


The goals obtained with the current management of dental caries has given the dentists the opportunity to detect incipient caries lesions in early stages. Although, the current existence of a great variety of direct restorative materials available in the market to restore small caries lesions, the material that may show better success for these type of lesions, is without any doubt: the gold foil or direct gold (AU)

ABSTRACT

Tooth preparation is the primary and core operation technique for dental esthetic restoration treatment, due to its effect of providing restoration space, bonding interfaces and marginal lines for dental rehabilitation after tooth tissue reduction. The concept of microscopic minimal invasive dentistry put forward the issue of conducting high-quality tooth preparation, conserve tooth-structure, protect vital pulp and periodontal tissue simultaneously. This study reviewed the concepts, physiology background, design and minimal invasive microscopic tooth preparation, and in the meantime, individualized strategies and the two core elements of tooth preparation (quantity and shape) are listed.

ABSTRACT

La remoción y reemplazo de las restauraciones durante la vida del paciente puede resultar en anchas y profundas cavidades, por lo que es necesario ser conservador cuando se requiere un reemplazo. Evaluar el incremento de volumen en cavidades clase I en molares humanos, posterior a la remoción de restauraciones de resina compuesta y amalgama dental por diferentes grupos de operadores. Se seleccionaron 60 individuos pertenecientes a 4 grupos: Estudiantes de pregrado G1, estudiantes de postgrado G2, Profesores del Departamento de Odontología Restauradora G3 y Odontólogos Generales de Servicios Públicos G4. Cada operador respondió el Test de Conocimientos de Mínima Intervención en Odontología (MIO), y luego removió dos restauraciones; una de resina (RC) y otra de amalgama (AD). Para la preparación de las muestras se realizó una copia de la cara oclusal de los dientes con acrílico y se obtuvo un molde del diente sano. Posteriormente, se hizo la preparación Oclusal (Clase I Black), se tomó el registro del volumen inicial con material de impresión polivinil siloxano aplicando la ecuación v = m/d; se obturaron las cavidades y luego de la remoción se hizo un segundo registro para evaluar el incremento de volumen. Para el análisis se usaron modelos estadísticos descriptivos y modelos estadísticos inferenciales (ANOVA Bifactorial Univariante, MANOVA Bifactorial y relación lineal). Al comparar conocimientos de MIO y grupos de operadores (ANOVA) no encontró diferencia estadísticamente significativa. El diferencial de volumen (MANOVA) no encontró diferencia significativa entre grupos de operadores y materiales. En el estudio de relación lineal no existe relación predictiva entre Puntaje del Test de MIO e incremento de volumen de las cavidades. En las condiciones que se realizo esta investigación el incremento de volumen de las cavidades posterior al recambio no dependen de la experiencia individual de los diferentes grupos de operadores


The removal and substitution of restorations during the patient's life can result in wide and deep cavities. Hence, it is necessary to be conservative when a substitution is required. The purpose of this research was to evaluate the increment of volume in class I cavities after removing composite and amalgam restorations by different groups of operators. 60 people belonging to one of these groups were selected: undergraduate students G1, graduate students G2, professors of the department of restorative dentistry G3, and general dentist working in public services G4. Each operator answered the test of knowledge on Minimal Invasive Dentistry (MID), and the he/she removed two restorations: one of composite (C) and other of amalgam (DA). For the reparation of the sample teeth a copy of the occlusal surface with acrylic and a mold of the healthy tooth were obtained. Later, occlusal preparation was performed (Class I Black). Initial volume was registered with polivinil siloxane material and using the equation v=m/d. then, cavities were filled and a second register or volume was performed after remotion to evaluate volume increment. Inferential statistical tests were performed to analyze the data (1-way ANOVA, MANOVA and lineal regression). When comparing knowledge about MID and groups of operators, the ANOVA did not show statistically significant differences. The MANOVA analysis indicated that differential volume was not statistically significantly different among the groups of operators and materials. The lineal regression analysis indicated that there is not predictive relationship between the test of MIO's scores and increment of volume in cavities. Under the conditions of the present study, cavities volume increment does not depend on operator's experience
