“…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]. Recently, it was reported that increasing the distance of laser application and time of irradiation promoted a significant effect on dentin bond strength and microleakage scores to resin-based composites [42]. However, in a systematic review that aimed to find out which might be the most adequate adhesive and laser parameters for adhesion in dentin prepared with Er,Cr:YSGG laser, the following parameters: 2 W of power, pulse duration of 140 µs, repetition rate of 20 Hz and energy density of 50.96 J cm −2 were highlighted as the most adequate parameters.…”

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.

“…Los estudios han evaluado el efecto de los láseres de erbio en la morfología superficial de la dentina y han mostrado un aspecto irregular, sin capa de frotis y con túbulos dentinarios abiertos, con un patrón morfológico microretentivo favorable a los procedimientos de adhesión y haciéndola más resistente a la desmineralización a pH bajo. Dicho sistema de fototerapia funciona con el principio de microexplosión durante la ablación de tejido, lo que da como resultado irregularidades micro y macroscópicas en la superficie sin daños colaterales significativos a la estructura del diente, efectos térmicos o malestar del paciente 16 .…”

Objetivo: Analizar el daño pulpar por microfiltración en restauraciones con resina en dientes posteriores. Método: De tipo bibliográfica documental, Se escrutaron 18 investigaciones. Resultados: La contracción de polimerización provoca el desprendimiento de los márgenes del esmalte y / o pueden formar espacios que resultan en microfiltración marginal que permite el paso de bacterias, fluidos, moléculas o iones entre la superficie de la cavidad y resina compuesta. Conclusión: La microfiltración es un proceso por el cual se da una invasión bacteriana por la permeabilidad o brecha que existe entre la superficie dental y la restauración debido a la contracción del material después de la polimerización, fuerzas de masticación o condiciones del ambiente bucal, que da como resultado caries recurrentes y patología pulpar.

“…However, due to polymerization shrinkage and consequently the gaps created at the resin-tooth interface, the use of these materials increases the risk of microleakage, tooth and pulpal sensitivity, and recurrent caries. [1][2][3][4] Population aging has elevated the cases with gingival recession and subsequently the incidence of root caries, which are confined to dentin with no enamel involvement. This has given rise to more research on the restoration of root caries.…”

Introduction: This study was conducted to assess the microleakage in Er:YAG laser-ablated and bur-prepared root and coronal dentin cavities using self-etch and total-etch adhesive systems. Methods: Sixty extracted caries-free human third molars were sectioned for dentin exposure. Then, two standard class V cavities were prepared in the root and coronal dentin of each tooth and allocated to one of the following conditioning groups randomly (n=12/Group): G1: Diamond bur for cavity preparation and single bond (BESB) etch-and-rinse adhesive for bonding, G2: Er:YAG laser (160 mJ, 20 Hz, 29.88 J/cm2 ) and SB (LESB), G3: Er:YAG laser and SB without acid etching (LSB), G4: Diamond bur and Clearfil SE Bond (BCSE) self-etch system, and G5: Er:YAG laser and Clearfil SE Bond (LCSE). The cavities were filled with Z100 composite resin. Dye penetration was assessed after thermocycling. Data analysis was done by Kruskal–Wallis and Mann–Whitney U tests. Statistical significance was set at P<0.05. Results: The results showed there were no statistically significant differences in microleakage between the two preparation methods (bur and laser) or the bonding agents applied (P>0.05). Regardless of the cavity preparation method, dye penetration was significantly higher in coronal dentin than in root dentin (P<0.05). Conclusion: The Er:YAG laser had the same efficacy as the conventional method for cavity preparation, and microleakage did not depend on the bonding agent. Microleakage was significantly higher in coronal restorations than in root restorations.
