MDP-based universal adhesive system irradiated with Er,CR:YSGG: Analysis of its performance up to 6 months

Abstract

This study aimed to analyze the interaction of a MDP-based universal dentin bonding system (DBS) with Er, Cr: YSGG laser irradiation, measuring the microtensile bond strength to dentin over a six-month period. The experimental design involved three factors: DBS (Adper Scotchbond Universal; Clearfil SE Bond, Adper Scotchbond Multipurpose and Adper Single Bond 2), laser (Control and Er, Cr: YSGG), and time (initial-7 days and 6 months). Eighty dentin samples from molars were prepared (n=10) with laser irradiation after primer and DBS application. After 7 days, were subjected to micro tensile bond strength test. The data were analyzed by three-way ANOVA and Tukey tests (p<0.05). Both DBS and laser significantly affected the bonding performance and their interaction was statistically significant (p=0.0194). The self-etching mode of the MDP-based universal DBS maintained the bond strength on dentin irradiated with ER, Cr: YSGG after 6 months, while bonding with all other DBS deteriorated.

Effect of Er, Cr: YSGG laser irradiation in the physics properties of different dentin bonding systems

“…Irradiated groups were affected negatively, with exception SU-L that did not present a significant drop in the MS values. These data corroborate the work of Zabeu et al,2021 however in the period of 6 months. Drop in bond strength values over time are expected (Yoshida et al, 2012) regardless of the adhesive type, however the laser irradiation promoted a significantly greater drop.…”

Comparación In Vitro de la resistencia adhesiva microtraccional de la unión resina-dentina usando dos sistemas adhesivos

“…Los resultados del presente estudio muestran que la media de la resistencia adhesiva microtraccional del sistema adhesivo de sexta generación presenta una media de 23.29 MPa y del sistema adhesivo de octava generación reportó una media de 18.75 MPa, discrepando con los resultados del estudio de Costa y Cols., 10 Cols., 20 evaluaron la interacción de un sistema de unión universal en dentina (DBS) basado en metacriloiloxidocil dihidrógeno fosfato (MDP) con Er, Cr:…”
