“…No direct correlation between Er,Cr:YSGG laser power and surface roughness of lased dentin was found [27]. Different laser parameters and their effect on dentin bond strength were previously evaluated [38]. It was shown that all dentin lased groups exhibited decreased bond strength and no significant differences were observed regardless of the laser parameters used [38].…”

Over time teeth are exposed to several physical-chemical alterations, which may change the dental structure. Therefore, dental clinicians must be aware of how to manage the altered tissue. Laser irradiation and self-etch adhesives may be an option in this situation. This study aimed to evaluate the bond strength of self-etch adhesive systems associated with different treatments on hypermineralized dentin. 80 bovine incisors were distributed into two groups: Universal (3M ESPE; n = 40) and Optibond All in One (Kerr; n = 40). Five treatments were performed for each group (n = 8): (T1) adhesive system (control); (T2) acid + adhesive; (T3) Er,Cr:YSGG laser + adhesive; (T4) acid + Er,Cr:YSGG laser + adhesive; (T5) Er,Cr:YSGG laser + acid + adhesive. After bond and restorative procedures, teeth were submitted to microshear bond strength test. ANOVA two-way followed by Games-Howell Test was performed. Statistical significance difference was observed for adhesive systems and treatments (p ⩽ 0.001). For the adhesives used, Universal adhesive system presented the highest average bond strength. The highest bond strength was obtained in the control group (T1), T3 and T4. Laser irradiation may be a viable option as a surface pretreatment on hypermineralized dentin when self-etch adhesives are used.

“…The µTBS of self-etch adhesive on bovine teeth was compared with the control group. The results showed that different laser irradiation settings negatively affected the bonding strength of the adhesive systems at the resin-dentin interfaces (42). In another study, the µTBS of dentin surfaces irradiated with Er:YAG and Er, Cr: YSGG lasers were examined, and samples treated with laser irradiation had lower µTBS values than the control group (43).…”

The purpose of this study was to compare the effect of different disinfection protocols of dentin on bond strength of an MDP-containing universal adhesive. Twelve extracted mandibular third molars were separated horizontally at the mid-coronal of crown to get smooth and sound dentin surfaces using low-speed diamond saw. The teeth were randomly fallen into four groups: chlorhexidine (CHX), ozone, Er,Cr:YSGG laser irradiation (LASER) and no treatment (control). After cavity disinfection application, a universal adhesive (G-Premio Bond) was applied to the surface of dentin according to self-etch mode as instructed by the manufacturer. After incremental built-up of composite resin (Charisma Smart), the specimens were immersed in distilled water at 37°C for 24h. Dentin/composite beams with 1 mm² cross sectional area were produced and micro-tensile bond strength (µTBS) was applied on these beams (n=20). Failure mods were determined under a stereomicroscope at ×40. The resin penetration of samples stained with Rhodamine B fluorochrome dye was examined with a confocal laser scanning microscope. Statistical analysis was performed with SPSS-22. Test results were analyzed using One-way Anova and Tukey HSD Post-Hoc tests (p<0.05). The µTBS value of control (35.13±6.20) was the highest statistically among the groups (p<0.05). The lowest µTBS were obtained by LASER (19.25±4.66) and CHX (23.07±7.01). There was no significant difference between CHX and LASER, and between CHX and ozone (p>0.5). All applications of cavity disinfection procedures decreased the µTBS of the resin-dentin interface.

“…28,29 These morphological alternations might negatively affect resin hybridization. 30 During dentin laser irradiation, heat is generated, resulting in thermal denaturation of the collagen, breaking of the hydrogen bonds, and three-polypeptide chains in a triple helical molecular structure, which results in an irreversible transformation and shrinkage of the collagen fiber network. 31 To minimize the effect of erbium laser irradiation on dentin, proper laser parameters should be selected.…”

Introduction: The presence of gaps at the bonding interface of resin composite restorations is known to have an impact on restoration longevity. This study aimed to evaluate the effect of erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er, Cr:YSGG) laser irradiation on gap formation at the tooth–resin interface and to compare the reliability of micro-computed tomography (µCT) and scanning electron microscopy (SEM) scans for gap formation assessment. Methods: Thirty standardized non-retentive class V cavities were prepared on sound human premolars using either an Er,Cr:YSGG laser or a round carbide bur (n=15 for each). A universal adhesive and A nano-filled resin composite were applied in accordance with the manufacturer’s recommendations. After water storage for 24 hours at 37°C, the teeth were subjected to thermocycling. Gap formation assessments were performed by µCT (Skyscan 1173 µCT, Brucker, Belgium) and SEM (JEOL JSM-6610LV, Japan), and SPSS version 24.0 (IBM Inc., Chicago, USA) was used to analyze the data at P value<0.05. Descriptive statistics were used to describe the gap formation percentages. To compare the impact of both preparation and assessment methods, a non-parametric Mann–Whitney U test was used. Results: In enamel, similar gap formation values were detected for the two preparation methods (bur and laser). However, the laser-prepared group showed higher gap formation values in dentin. Additionally, higher gap formation values were reported for both preparation methods when µCT was used for assessment. Conclusion: Cavity preparation using a Waterlase laser led to higher gap formation percentages at the dentin–resin interface. In addition, SEM assessment is more reliable for assessing the tooth–resin interface.
