| dc.description | Objetivos: Evaluar la influencia de un desensibilizante a base de glutaraldehído (GL) sobre la sensibilidad postoperatoria (POS) en restauraciones posteriores de composite de resina bulk-fill utilizando un adhesivo aplicado en las estrategias de autograbado (SE) y etchand-rinse (ER); y evaluar el rendimiento clínico de las restauraciones. Métodos: Se insertaron restauraciones posteriores de composite de resina (n = 228) de al menos 3 mm de profundidad en 57 sujetos utilizando un diseño de boca dividida. El adhesivo se aplicó con/sin aplicación previa de un GL. En todas las restauraciones se utilizó un composite de resina. Se evaluó la POS espontánea (riesgo e intensidad), así como la POS provocada por la estimulación con un chorro de aire y se valoró la respuesta a la percusión horizontal y vertical mediante dos escalas en la línea de base y después de 7, 14 y 30 días. Además, se evaluaron algunos parámetros utilizando los criterios del IED hasta los 24 meses de servicio clínico. Resultados: No se observó ningún TPV significativo (p > 0,05). Se observó un mayor riesgo absoluto e intensidad de POS espontánea a los 7 días (35,1%), sin diferencias estadísticamente significativas entre grupos. A los 24 meses 5 restauraciones se consideraron clínicamente insatisfactorias, y 73 restauraciones mostraron discrepancias menores en la adaptación, sin diferencias significativas entre grupos (p > 0,05). Significado: Un agente GL no influye en el POS en restauraciones posteriores con composite de resina bulk-fill. Puede considerarse un paso clínico prescindible en el protocolo restaurador. | |
| dc.description.abstract | Objectives: To evaluate the influence of a glutaraldehyde-based desensitizer (GL) on postoperative sensitivity (POS) in posterior bulk-fill resin composite restorations using an adhesive applied in the self-etch (SE) and etchand-rinse (ER) strategies; and to assess the clinical performance of the restorations. Methods: Posterior resin composite restorations (n = 228) at least 3 mm deep were inserted in 57 subjects using a split-mouth design. The adhesive was applied with/without prior application of a GL. A resin composite was used for all restorations. Spontaneous POS (risk and intensity), as well as POS caused by stimulation with an air blast and assess the response to horizontal and vertical percussion was assessed using two scales in the baseline and after 7, 14, and 30 days. In addition, some parameters were evaluated using FDI criteria up to 24 months of clinical service. Results: No significant POS was observed (p > 0.05). A higher absolute risk and intensity of spontaneous POS was observed within 7 days (35.1%), without statistically significant differences among groups. At 24 months 5 restorations were considered clinically unsatisfactory, and 73 restorations showed minor discrepancies in adaptation, with no significant differences between groups (p > 0.05). Significance: A GL agent does not influence POS in posterior restorations with bulk-fill resin composite. It may be considered a dispensable clinical step in the restorative protocol. | |
