Resumen
La lesión cervical corresponde a la pérdida patológica de tejido del límite
amelocementario de etiología multifactorial. Los materiales restauradores
incluyen resina compuesta, vidrio ionómero convencional y modificado con
resina. El objetivo de esta investigación fue comparar el comportamiento clínico
de restauraciones cervicales de resina compuesta y vidrio ionómero a 2 años
de su realización, según criterios Ryge.
Este estudio analítico de cohorte contó con una muestra de 102
restauraciones cervicales: 52 de resina compuesta y 50 de vidrio ionómero.
Para obtener la muestra se citaron pacientes que recibieron restauraciones
cervicales el año 2009, realizadas por alumnos de Odontología de la UNAB.
Posteriormente los datos se analizaron con la prueba de Chi-cuadrado.
De 102 muestras, 1 O se encontraron ausentes, 8 correspondientes a
vidrio ionómero, existiendo una asociación directa entre ausencia-restauración
(Pr=0.039). Para los criterios Ryge, igualdad de color, textura superficial y
contorno se obtuvo una asociación directa a favor de las restauraciones de
resina compuesta (Pr=0.000, Pr=0.000 y Pr=0.005). La decoloración, integridad
marginal y presencia de caries recurrente no presentaron una asociación
significativa con la restauración (Pr=0.080, Pr=0.568 y Pr=0.901 ).
Las restauraciones cervicales de resma compuesta poseen mejor
permanencia y comportamiento clínico en Igualdad de color, textura superficial
y contorno que el vidrio lonómero a los 2 años. La decoloración, integridad
marginal y presencia de caries recurrente no presentaron diferencias
significativas.
The cervical lesion corresponds to the pathological loss of tissue of the enamel-cement limit of multifactorial etiology. The restorative materials include composite resin, conventional glass ionomer and resin modified ¡onomer. This investigation aimed to compare the clinical performance of cervical restorations of composite resin and glass ionomer upon 2 years from their realization, foliowing the Ryge criteria. This analytical study of cohort consisted in a sample of 102 cervical restorations; 52 of composite resin and the remaining 50 using glass ionomer. Observations were obtained from patients receiving cervical restorations performed by dental students of UNAB, in 2009. Data were statistically analyzed with the chi-square test. Of 102 samples, 10 were found absent, with 8 of them being glass ionomer restorations. A direct association between absence and restoration was found (Pr=0.039). For the Ryge criteria of evenness of color, surface texture and contour, direct associations were obtained for composite resin restorations (Pr=0.000, Pr0.000 and Pr=0.005). Discoloration, marginal integrity and presence of recurrent caries showed no significant association with restoration (Pr=0.080, Pr=0.568 and Pr=0.901). The cervical restorations of composite resin possessed better permanency and clinical performance in terms of equality of color, superficial texture and contour than the glass ionomer after 2 years. Discoloration, marginal integrity and presence of recurrent caries did not present significant differences.
