Prolonged application methods of self-etching primer: Effect of aging on micro-shear bond strength to lithium disilicate and zirconia-reinforced lithium silicate ceramics Camilo Pulido, Omaira Prieto‐Torres, Cristhian Carvajal‐Garzón, Andrés Dávila‐Sánchez, Claudia Gonzalez‐Vaca, et al. Journal of Prosthodontics, 2026 Purpose To evaluate the effect of different self‐etching primer (Monobond Etch & Prime—MEP) application protocols and aging on micro shear bond strength (µSBS) and surface etching patterns of zirconia‐reinforced lithium silicate (ZLS) and lithium disilicate (LD) ceramics. Materials and Methods Twenty‐eight blocks of Vita Suprinity (VS), Celtra Duo (CD), and IPS e.max CAD (EM) were cut into two sections each ( n = 56 specimens per ceramic) and divided into groups: 5% hydrofluoric acid with silane (HF + S, control), and MEP scrubbing for 20, 40, and 60 s, with a 40‐s reaction time ( n = 14 per condition; n = 10 for µSBS and n = 4 for scanning electron microscopy [SEM]). For µSBS, resin cement was applied and light‐cured; half of the resin cylinders were stored for 24 h, while the other half underwent thermocycling (TC) (10,000 cycles; dwell time of 30 s between 5°C and 55°C) before testing. Data were analyzed using three‐way repeated measures analysis of variance (ANOVA) and Bonferroni post hoc tests ( α = 0.05). Results The HF + S group showed higher µSBS for EM than VS and CD ( p < 0.001). MEP100 achieved comparable µSBS with HF + S for CD ( p < 0.001) and improved µSBS for VS and EM ( p = 0.128). TC decreased the µSBS values in most groups. The only exception was observed when the VS and CD surfaces were treated with MEP100, and when the CD surface was treated with MEP80. Adhesive fractures were predominantly seen. SEM revealed MEP100 produced etching patterns like HF, with lithium metasilicate and orthophosphate crystals present. Conclusions Prolonged MEP application (MEP100) produced etching patterns and µSBS values comparable to HF + S, making it a viable surface treatment alternative for ZLS and LD ceramics.
Effect of the Use of Modeling Liquids on Vickers Hardness, Degree of Conversion, and Light Transmission of Bulk-Fill Resin Composites: Part II Paul Álvarez, Camila Falconi‐Páez, Alejandra Núñez, Newton Fahl, Paulina Aliaga, et al. Journal of Esthetic and Restorative Dentistry, 2026 Objective To evaluate the effect of modeling liquids on Vickers microhardness (VHN), degree of conversion (DC), and light transmittance in bulk‐fill resin composites (BFRC). Materials and Methods One hundred and thirty‐two specimens were prepared using three BFRC (TNBF: Tetric N‐Ceram Bulk‐fill; OBF: Opus Bulk‐Fill; and FBF: Filtek One Bulk‐Fill) and three modeling liquids (AM: Ambar Universal; MR: Modeling Resin, and WR: Wetting Resin). VHN and DC were evaluated at 1‐, 2‐, 3‐, and 4‐mm depths. Light attenuation was assessed using a calibrated integrated sphere. Confocal laser scanning microscopy (CLSM) was used to assess the presence and thickness of the modeling liquid layer on the specimen surface. VHN data were analyzed with 2‐way repeated measures ANOVA, followed by Bonferroni post hoc test; light transmittance and DC data were analyzed using Kruskall‐Wallis followed by Bonferroni post hoc test and Spearman test followed by Dwass‐Steel‐Critchlow‐Finger post hoc test. Results FBF‐AM presented lower VHN values at 1‐mm ( p < 0.05). All experimental groups increased DC, with WR in all BFRC ( p < 0.016), AM in the TNBF and FBF ( p < 0.0016; p < 0.001), and MR exclusively in OBF ( p < 0.001). MR increased light transmittance in all BFRC; WR in FBF and TNBF; and AM in FBF ( p < 0.05). CLSM images showed the presence of modeling liquids post‐polishing. Conclusion Modeling liquids may enhance VHN, DC, or light transmittance when used in BFRC, depending on the modeling liquid and BFRC type. Clinical Significance The choice of modeling liquid can influence the physical and chemical properties of bulk‐fill resin composites. Proper selection may enhance the degree of conversion and hardness without compromising material performance.
In vitro assessment of the role of air spray on pulp temperature changes for preheated resin composite Class V restorations in lower incisor Vinicius Borges Oliveira, Juliana Anany Gonzales Guarneri, Milena Ferreira Machado, Lucas Arrais Campos, Cesar Augusto Galvão Arrais Odontology, 2026 To evaluate the effect of 15- and 30-psi air spray on in vitro pulp temperature (PT) during light-curing of buccal Class V restorations in lower incisors using preheated resin composites (RBCs). After ethical approval, a Class V cavity was prepared in a sound lower central incisor. A T-type thermocouple was inserted into the pulp chamber and connected to a temperature measurement system (Thermes WiFi, Physitemp). Simulated pulpal fluid flow was maintained at a rate of 0.001 mL/min. Real-time PT and working time were recorded during restoration with Viscalor Bulk-fill (VOCO) and Filtek One Bulk-fill (Solventum) preheated to 68 °C. Air spray (15 or 30 psi) was directed to the lingual surface, starting 3 s before and maintained throughout light-curing ( n = 9). Vickers hardness (VHN) was measured at the middle and inner surfaces near the top and bottom of each specimen. PT and VHN data were analyzed using nonparametric mixed ANOVA, and working time was analyzed using nonparametric two-way ANOVA, both followed by Bonferroni’s post hoc tests ( α = 0.05). Light-curing of preheated RBCs significantly increased PT (42.5 ± 1.3 °C; p < 0.001). Air spray at 15 and 30 psi reduced PT values (28.4 ± 1.3 °C and 26.8 ± 1.8 °C, respectively; p < 0.001) without affecting VHN values. Air spray during light-curing effectively minimized pulp temperature rise during restorative procedures using preheated RBCs on lower incisors.
Effect of Three Heating Guns on the Temperature of Two Bulk-Fill Resin-Based Composites Juliana Anany Gonzales Guarneri, Cristiane Maucoski, Fabrício Mezzomo Collares, Richard Bengt Price, Cesar Augusto Galvão Arrais Journal of Esthetic and Restorative Dentistry, 2025 ObjectiveTo evaluate the effect of three heating guns—Phasor (Vista Apex, Racine, USA), VisCalor (VOCO, Cuxhaven, Germany), and Compex HD (AdDent Inc. Danbury, USA)—on the temperature changes of two bulk‐fill resin‐based composites (RBCs): VisCalor Bulk (VBF, VOCO) and Filtek One Bulk Fill Restorative (OBF, Solventum, St. Paul, USA).Materials and MethodsTemperature changes were measured using a thermal camera (PI 640i, Optris Infrared Measurements, Berlin, Germany) during insertion and photocuring in a simulated proximal box of a Class II cavity and within the RBC capsules during heating. The RBCs were photocured using the Bluephase PowerCure (Ivoclar, Schaan, Liechtenstein) for 20s. Data were analyzed using repeated measures ANOVA and Tukey's test for each RBC (α = 0.05). The temperature of the RBCs at the same depth were analyzed by t‐test (α = 0.05).ResultsOBF heated with Compex produced the lowest temperature rise at the pulpal floor (2.7°C ± 0.4°C), while VBF heated with Phasor produced the highest (8.8°C ± 2.4°C). The greatest temperature increases were at the top of the restoration. OBF heated with Phasor reached 48.6°C ± 4.7°C. The Phasor and VisCalor produced two temperature peaks in the RBC inside the capsule, while the Compex maintained a steady peak temperature.ConclusionThe heating gun and RBC produced different temperatures when heating, inserting, and light‐activation of the RBCs.Clinical SignificanceThe choice of RBC and heating gun can substantially affect the temperature of the RBC and influence its handling properties.
How Universal Adhesive Systems With Nanoencapsulated Flavonoids Improve Long-Term Bonding to Caries-Affected Dentin Camila Falconi‐Páez, Mayra Alejandra Nuñez Aldaz, Tobia Gastón Navarro, Claudia Carolina González‐Vaca, Lucas Arrais Campos, et al. Journal of Esthetic and Restorative Dentistry, 2025 ObjectivesTo determine the presence of nano‐encapsulated flavonoids and their effect in universal adhesives on resin‐dentin bond‐strength (μTBS) and nanoleakage (NL) on artificial caries‐affected dentin (CAD) after 24‐h and 6 months of water storage (WS).Materials and MethodsArtificial CAD was created on the occlusal dentin surfaces of 60 human third molars by a microbiological assay. Nanoencapsulated quercetin (Q) and naringin (N) were incorporated into Prime&Bond Universal (PBU; Dentsply‐Sirona) and Single Bond Universal (SBU, 3M ESPE). The adhesive systems with and without (control) flavonoids were applied to the CAD surface, and a 4‐mm resin composite block (TPH Spectrum, Dentsply Sirona) was built up and light‐cured. Specimens were sectioned into resin‐dentin beams (0.8 mm2). The hybrid layer (HL) was subjected to micro‐Raman analysis to detect N and Q. The specimens were tested in tension in a universal testing machine at 0.5 mm/min. μTBS and NL tests were performed after 24‐h and WS. μTBS and NL data were analyzed using a nonparametric three‐way ANOVA test followed by Bonferroni's test (α = 5%).ResultsQ and N were detected within the HL. N and Q nanocapsules increased μTBS and reduced NL values after WS. At 24 h, the PBU group showed higher NL values than the SBU group, and the values decreased after WS.ConclusionsIncorporating nanoencapsulated flavonoids may improve the longevity of universal bonding systems applied to CAD.Clinical RelevanceAdhesive restorations incorporating nanoencapsulated quercetin or naringin might be a promising alternative for achieving long‐term bonding stability.
