“…Experimental results by Rechman et al showed that Er:YAG laser can debond all ceramic crowns (lithium‐disilicate and zirconium‐oxide) without damaging underlying tooth structures. Similar results have been reported in other experimental and clinical studies. However, to date there are no guidelines available for laser‐assisted removal of all ceramic FDPs.…”

“…A limited number of studies have reported the use of erbium lasers as a suitable alternative to remove all ceramic FDPs. Erbium lasers such as erbium, chromium:yttrium scandium gallium‐garnet (Er:CrYSGG) and erbium:yttrium‐aluminum‐garnet (Er:YAG) emit light at a wavelength ranging between 2780 nm and 2940 nm .…”

“…Rechmann et al evaluated temperature changes in the pulp chamber during laser assisted removal of all ceramic crowns. Gurney et al compared the time required to remove lithium disilicate crowns using erbium laser and high‐speed with diamond burs. The results showed that laser assisted removal of lithium disilicate crowns can be fulfilled in 60–90 s, compared with approximately 360 s with high‐speed and diamond burs .…”

“…This mechanism involves vaporization followed by hydrodynamic ejection . The restoration can be removed intact without any residual cement in the inner surface; the residual cement remains attached to the tooth structure and can be easily removed with a polishing cup, a dull instrument or gauze . It is therefore tempting to speculate that erbium lasers are a valuable and predictable tool for the removal of all ceramic FDPs.…”

Benefits of lasers over mechanical instrumentation for crown removal encompass efficient restoration retrievability without restoration or teeth surfaces damages; and relatively easier and time effective procedure with no prerequisite for anesthetic agents. It is however imperative for clinicians to be well-trained and exhibit adequate knowledge regarding recommended power settings and laser-safety parameters with reference to interactions between light and different tissues and ceramics.

Laminate veneer removal is becoming a routine procedure at the dental clinic and the use of laser can facilitate its removal. This work aimed to evaluate the morphological, elemental, and optical changes in the remaining enamel after veneer removal using Er,Cr:YSGG laser. Forty‐four enamel slabs were prepared and randomly distributed into nine experimental groups, for bonding using lithium disilicate laminates with three different luting agents (Variolink Veneer, RelyX U200, and RelyX Veneer). Then each agent was debonded using Er,Cr:YSGG laser (2.78 μm) using two different protocols:3.5 W, 48.14 J/cm2, 20 Hz non‐contact and 3.0 W, 48.14 J/cm2, 20 Hz non‐contact. The morphological, optical, and elemental analysis of enamel was performed before cementation and after laser debonding, using scanning electron microscopy (SEM), optical coherence tomography (OCT), and energy‐dispersive X‐ray spectroscopy (EDS). The level of statistical significance adopted was 5%. The EDS analysis of enamel after debonding revealed a significant increase in silane and carbon, as well as a decrease in calcium and phosphate contents. Analysis showed the presence of residual cement in most experimental groups but the morphological analysis showed alteration of the enamel's prisms only in the groups that used RelyX Veneer and Variolink Veneer cements. There was no evidence of deleterious morphological changes resulting from irradiation. However, an increase in the optical attenuation coefficient by the OCT was observed due to the presence of the remaining cement. It can be concluded that the Er,Cr:YSGG laser, in the mean powers used, is efficient for veneer removal without causing deleterious effects for the enamel.
