ABSTRACT

Objective:

To assess the six-month clinical outcome of restorations of non-carious cervical lesions (NCCL) with two composite resins Bulk-Fill and nanohybrid resin. Materials and

methods:

Fifty-one patients, with three NCCLs each, were randomly allocated into three restoration groups Tetric-N-Ceram Bulk-Fill (TB); Filtek Bulk-Fill (FB); y Filtek Z350XT (Z350). Adhesive techniques and restorative procedures were performed according to the manufacturers' instructions for the different materials. A 4mm increment was applied in TB and FB, and increments of ≤2mm depth were applied in Z350. Restorations were assessed by two calibrated examiners at baseline and at six months according to the FDI World Dental Federation guidelines (1 excellent, 2 acceptable, 3 sufficient, 4 unsatisfactory, 5 unacceptable) in Marginal Staining (MS), Fracture-Retention (FR), Marginal Adaptation (MA), Postoperative Sensitivity (S) and Caries (C). Wilcoxon test was used for the comparison between baseline and 6 months, and Kruskal-Wallis for the comparison of the three groups at six months (95% significance).

Results:

Forty-six patients with a total of 138 restorations attended a check-up at six months and were evaluated with excellent clinical outcome. In MS, 91.2% for Z350 and 97.8% for FB and TB; in FR, 97.8% for Z350 and 100% for FB and TB; in MA, 95.6% for Z350, 97.8% for FB and 100% for TN; in S, 95.6% for all three groups; and 100% for C. No statistically significant differences were found between the three groups nor in the comparison between the baseline and 6 months (p>0.05)

Conclusion:

No significant differences are observed between the three groups of resins in the parameters of MS, MA, S, FR and C regarding clinical outcome at six months.
RESUMEN

Objetivo:

Evaluar el comportamiento clínico a 6 meses en restauraciones de lesiones cervicales no cariosas (LCNC) con dos resinas compuestas Bulk-Fill y una resina nanohíbrida. Materiales y

métodos:

En 51 pacientes se restauraron 3 LCNC distribuidas aleatoriamente en 3 grupos, TB Tetric-N-Ceram Bulk-Fill, FB Filtek Bulk-Fill y Z350 Filtek Z350XT. Las técnicas adhesivas y procedimientos restauradores fueron realizados según las instrucciones de los fabricantes para los diferentes materiales. En TB y FB se aplicó un incremento de 4mm y en Z350 se aplicó incrementos ≤2mm de profundidad. Dos operadores calibrados evaluaron las restauraciones al baseline y 6 meses mediante los criterios clínicos FDI (1 excelente, 2 aceptable, 3 suficiente, 4 insatisfactorio, 5 inaceptable) en Tinción Marginal (TM), Fractura-Retención (FR), Adaptación Marginal (AM), Sensibilidad Postoperatoria (S) y Caries (C). Se utilizó Wilcoxon para la comparación entre baseline ­ 6 meses y Kruskal-Wallis para la comparación de los 3 grupos a 6 meses (significancia de 95%).

Resultados:

A los 6 meses asistieron 46 pacientes con un total de 138 restauraciones siendo evaluados con comportamiento clínico excelente; en TM 91,2% para Z350 y 97,8% para FB y TB; en FR, Z350 presentó 97,8% y en FB y TB el 100%; en AM, 95,6% para Z350, 97,8% para FB y 100% para TN; en S presentó 95,6% para los tres grupos; en C se presentó el 100%. No hubo diferencias estadísticamente significativas entre los 3 grupos y en la comparación de baseline - 6 meses (p>0.05).

Conclusión:

No existen diferencias significativas en el comportamiento clínico a 6 meses entre los 3 grupos de resinas en los parámetros TM, AM, S, FR Y C.
