Effects of nanosecond‑ and microsecond‑pulse Er, Cr: YSGG laser on the morphology and pulp temperature of dentin in dental restoration debonding.

Objective: This study evaluated dentin morphology and pulp cavity temperature changes during nanosecond‑ and microsecond‑pulse Er, Cr: YSGG laser debonding restoration and residual adhesive.

Materials And Methods: Ten caries-free teeth had their enamel removed perpendicular to the long axis, followed by bonding of glass ceramic restorations. The samples were randomly divided into two groups and subjected to Er, Cr: YSGG laser (3 mJ, 100 Hz, 100 ns), (3 mJ, 100 Hz, 150 µs) for debonding of restoration and residual adhesive on dentin surfaces.

Safety and Efficacy of the Erbium Laser in Debonding Dental Accessories: A Narrative Review.

This article aims to review the safety and efficacy of the Er:YAG laser in debonding dental accessories. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Articles published between 2010 and 2022 on the removal of dental accessories using erbium laser were searched.

Effect of nanosecond- and microsecond-pulse Er,Cr:YSGG laser ablation on dentin shear bond strength of universal adhesives.

Objective: The study aimed to evaluate the bond strength of universal adhesives to dentin after Er,Cr:YSGG laser irradiation with nanosecond-domain and microsecond-domain pulses.

Methods: Eighty extracted caries-free, sound human molars were divided into eight groups. The enamel was removed until the dentin occlusal flat dentin surface was exposed.

Effects of Dentin Ablation by a Q-Switching Er:YSGG Laser with a High Pulse Repetition Rate.

The aim of the study was to evaluate the characteristics of dentin ablation with a high pulse repetition rate Q-switching 2.79 μm laser. Dentin was ablated using a homemade Q-switching Er:YSGG laser with a high pulse repetition rate.
