Resumen
El presente documento presenta un estudio piloto realizado
durante el 2014 de acuerdo al año académico de la clínica odontológica de la
Universidad Andrés Bello, sede Santiago.
Una causa frecuente de consulta al odontólogo es la hipersensibilidad
dentinaria posterior a la cementación de restauraciones en piezas vitales. Sin
embargo, en la actualidad existen diferentes cementos y técnicas adhesivas
que podrían dar solución estos problemas.
Objetivo: Determinar clínicamente la presencia de hipersensibilidad dentinaria
pre-operatoria y posterior a la cementación de restauraciones indirectas
(incrustaciones estéticas) en piezas vitales (premolares y molares) utilizando
cemento de resina: convencional y autograbante.
Materiales y métodos: Se evaluaron 30 pacientes y se conformaron 2 grupos
de 15 personas cada uno. Utilizando cementación adhesiva con grabado
convencional del sustrato dentario para grupo I vs cementación adhesiva
autograbante para el grupo II. Se realizó un test de sensibilidad inicial como
referencia “T1” de frío con spray refrigerante y calor con barra de gutapercha. Y
un segundo test realizado posterior a la cementación “T2”. Para finalmente,
comparar ambos grupos entre sí. La sensibilidad percibida por el paciente fue
objetivada a través de la escala de evaluación de sensibilidad de Schiff. (26)
Resultados: Al realizar el test U de Mann-Whitney (nivel de significancia
α=0,05),se obtiene que Ucrit>Umin (U1,U2), por lo tanto se acepta ho y se
concluye que la respuesta a la sensibilidad no se ve influida por el tipo de
cemento utilizado en las muestras analizadas.
Conclusión: Se determinó que, no hay diferencias estadísticamente
significativas al utilizar cemento de resina autograbante vs cemento de resina
de grabado total, aceptándose la hipótesis nula.
Palabras claves: cementación adhesiva, cementación adhesiva convencional,
cementos autograbantes, hipersensibilidad post-operatoria, test de
sensibilidad, cementos de resina.
This paper presents a study done during the 2014 according to academic year at the dental clinic of the Andres Bello university in Santiago. A frequent cause for consulting to the dentristy is dentin hypersensitivity postcementation of restorations in vital dental pieces . However, at present there are differents cements and adhesive techniques may provide solutions to these problems. Objective: To determine clinically the presence of dentin hypersensitivity preoperatory and post-cementation of indirect restorations (inlays esthetics) in vital dental pieces (premolars and molars) using resin cements: total etch (conventional) and self-etching. Materials and Methods: 30 patients were evaluated, conforming 2 groups of 15 people each one. Using conventional etching adhesive cementation for group I vs self-etch adhesive cementation for group II. For have a reference Initial, was performed a reference sensitivity test "T1" with cool spray and hot with gutapercha. And second test post cementation "T2" . To finally compare both groups. Perception by the patient was objectivized through the rating " Schiff scale sensitivity ". (26) Results: While testing Mann-Whitney test (α = 0.05 level of significance), we obtain that Ucrit> Umin (U1, U2), therefore accepts ho and concludes that the answer to the sensitivity is not is affected by the kind of cement used in the samples tested. Conclusion: It was determined that there are no statistically significant differences when using resin self-etch cement vs total etch resin cement, accepting the null hypothesis.
