Hydrolytic stability of three-Step Etch-and-rinse adhesives in occlusal class-I cavities
Clinical oral investigations, 2012Co-Authors: Jan De Munck, Atsushi Mine, Marcio Vivan Cardoso, Kirsten Van Landuyt, Anne Katrin Lührs, André Poitevin, Masao Hanabusa, Takuo Kuboki, Bart Van MeerbeekAbstract:Objectives A dental adhesive without small and hydrophilic monomers such as 2-hydroxyethyl methacrylate (HEMA) and triethylene glycol dimethacrylate (TEGDMA) would be beneficial in order to avoid contact allergies. However, these monomers are important to increase infiltration and polymerization of the adhesive. Therefore, the purpose of this study was to evaluate the bonding effectiveness and bond durability of a more hydrophobic and biocompatible adhesive as compared to a conventional three-Step Etch-and-rinse adhesive.

Effect of low-shrinking composite on the bonding effectiveness of two adhesives in occlusal Class-I cavities.
Dental materials journal, 2012Co-Authors: Atsushi Mine, Jan De Munck, Marcio Vivan Cardoso, Kirsten Van Landuyt, André Poitevin, Takuo Kuboki, Yasuhiro Yoshida, Kazuomi Suzuki, Bart Van MeerbeekAbstract:The purpose of this study was to evaluate if a low-shrinking composite can improve the bonding effectiveness of adhesives in highly constrained conditions. A low-shrinking composite ('els-extra low shrinkage', Saremco) was bonded in standardized occlusal Class-I cavities using a three-Step ('cmf', Saremco) and a two-Step Etch-and-rinse adhesive ('XP Bond', Dentsply). Both adhesives were also combined with a conventional composite ('Z100', 3M ESPE). Half of the restored cavities were exposed to 20,000 thermo-cycles. 3-way ANOVA revealed a significant effect for the factors 'adhesive' and 'composite' (both p

Clinical effectiveness of a one-Step self-Etch adhesive in non-carious cervical lesions at 2 years.
Clinical oral investigations, 2011Co-Authors: R Banu Ermis, Jan De Munck, Marcio Vivan Cardoso, Kirsten Van Landuyt, Bart Van Meerbeek, Marleen PeumansAbstract:A 2-year randomized, controlled prospective study evaluated the clinical effectiveness of a one-Step self-Etch adhesive and a “gold-standard” three-Step Etch-and-rinse adhesive in non-carious Class-V lesions. The null hypothesis tested was that the one-Step self-Etch adhesive does perform clinically equally well as the three-Step Etch-and-rinse adhesive. A total of 161 lesions in 26 patients were restored with Clearfil AP-X (Kuraray). The restorations were bonded either with the “all-in-one” adhesive Clearfil S3 Bond (Kuraray) or with the three-Step Etch-and-rinse adhesive Optibond FL (Kerr). The restorations were evaluated at baseline and after 6 months, 1 and 2 years, regarding their retention, marginal adapation, marginal discoloration, caries occurrence, preservation of tooth vitality and post-operative sensivity. Retention loss, severe marginal defects and/or discoloration that needed intervention (repair or replacement) and the occurrence of caries were considered as clinical failures. The recall rate at 2 years was 93.8%. Only one Clearfil S3 Bond restoration was lost at the 2-year recall. All other restorations were clinically acceptable. The number of restorations with defect-free margins decreased severely during the 2-year study period (to 6.7% and 25.3% for Clearfil S3 Bond and Optibond FL, respectively). The Clearfil S3 Bond restorations presented significantly more small marginal defects at the enamel side than the Optibond FL restorations (Clearfil S3 Bond: 93.3%; Optibond FL: 73.3%; p = 0.000). Superficial marginal discoloration increased in both groups (to 53.3% and 36% for Clearfil S3 Bond and Optibond FL, respectively) and was also more pronounced in the Clearfil S3 Bond group (p = 0.007). After 2 years, the simplified one-Step self-Etch adhesive Clearfil S3 Bond and the three-Step Etch-and-rinse adhesive Optibond FL were clinically equally successful, even though both adhesives were characterized by progressive degradation in marginal integrity. Clearfil S3 Bond exhibited more small enamel marginal defects and superficial marginal discolorations.

A 13-year clinical evaluation of two three-Step Etch-and-rinse adhesives in non-carious class-V lesions
Clinical oral investigations, 2010Co-Authors: Marleen Peumans, Jan De Munck, Kirsten Van Landuyt, André Poitevin, Paul Lambrechts, Bart Van MeerbeekAbstract:This 13-year randomized clinical trial compared the clinical effectiveness of two three-Step Etch-and-rinse adhesives in combination with a hybrid, stiffer composite versus a micro-filled, more flexible composite. The influence of composite stiffness on the clinical performance of one of the adhesives was assessed as well. One hundred and forty-two non-carious cervical lesions were restored with composites with contrasting stiffness. Seventy-one patients randomly received two cervical restorations placed following two out of three adhesive procedures: (1) the three-Step Etch-and-rinse adhesive Permaquick applied with the stiff micro-hybrid composite Amelogen Hybrid (PMQ-H, Ultradent), (2) Permaquick applied with the more flexible micro-filled Amelogen Microfill (PMQ-M, Ultradent), or (3) the “gold-standard” three-Step Etch-and-rinse adhesive Optibond FL applied with the micro-hybrid composite Prodigy (OFL-P, Kerr). The restorations were evaluated after 6 months, 1, 2, 3, 5, 7, and 13 years of clinical service regarding their retention, marginal integrity and discoloration, caries occurrence, preservation of tooth vitality, and post-operative sensitivity. Retention loss, severe marginal defects, and/or discoloration that needed intervention (repair or replacement) and the occurrence of caries were considered as clinical failures. The recall rate at 13 years was 77%. Bond degradation after 13 years was mainly characterized by a further increase in the presence of small but clinically acceptable marginal defects and superficial marginal discoloration. Twelve percent of the OFL-P restorations were clinically unacceptable. In the PMQ group, 22% of the PMQ-M restorations and 26% of the PMQ-H restorations needed repair or replacement. Regarding the clinical failure rate, Optibond FL scored significantly better than Permaquick (McNemar; p = 0.015). No statistically significant differences were found between the micro-filled and the hybrid composite for each of the parameters evaluated (McNemar, p > 0.05). After 13 years of clinical functioning, the clinical effectiveness of the three adhesive/composite combinations remained highly acceptable.

bonding effectiveness and interfacial characterization of a hema tegdma free three Step Etch rinse adhesive
Journal of Dentistry, 2008Co-Authors: Atsushi Mine, Jan De Munck, Kirsten Van Landuyt, André Poitevin, Takuo Kuboki, Paul Lambrechts, Yasuhiro Yoshida, Kazuomi Suzuki, Bart Van MeerbeekAbstract:Summary Objectives Small and hydrophilic monomers as HEMA and TEGDMA can easily penetrate human tissues. For biocompatibility issues it is therefore better to avoid such monomers in dental adhesive formulations. The purpose of this study was (1) to determine the micro-tensile bond strength (μTBS) to enamel/dentin of a HEMA/TEGDMA-free three-Step Etchr the μTBS to dentin was however significantly lower (p Conclusions The new three-Step adhesive cmf Adhesive System showed indications of good bonding effectiveness, certainly to enamel and only significantly lower to dentin, when compared to the gold-standard adhesive. The latter may be related to the adapted HEMA/TEGDMA-free formulation and the somewhat lower mechanical properties.

Journal of dentistry, 2018Co-Authors: Lidiane Costa De Souza, Vicente De Paulo Aragao Saboia, Victor Pinheiro Feitosa, N S Rodrigues, D A Cunha, Sérgio Lima Santiago, Alessandra Reis, Alessandro Dourado Loguercio, Thalita De Paris Matos, Jorge PerdigãoAbstract:Abstract Objective To compare the clinical behavior of Proanthocyanidins (PA)-free and PA-containing two-Step Etch-and-rinse adhesive used underneath resin composite restorations in non-carious cervical lesions (NCCLs) over a 6- (6 M) and 24-month (24 M) period. Methods 135 restorations were randomly placed in 45 subjects. The NCCLs were conditioned (37% phosphoric acid for 15 s) and distributed into 3 groups: Control (EX0) - ExciTE F (Ivoclar Vivadent) adhesive applied following the manufacturer's recommendations; EX2 and EX5 – 2 wt% and 5 wt% of PA were added to ExciTE F, respectively, and applied as in EX0. Resin composite was placed incrementally and light-cured. The restorations were evaluated at baseline, 6 M and 24 M, using FDI and USPHS criteria. Statistical analyses were performed using Friedman and Wilcoxon tests (α = 0.05). Results The retention rates were 98% (95% confidence interval 88–99%) for EX0, 92% (80–97%) for EX2; and 85% (72–93%) for EX5 at 6 M. A significant difference was found only for EX5 at 6 M when compared with the respective baseline findings (p = 0.03) and when compared with EX0 and EX2 (p = 0.001) at 6 M. After 24 M, the retention rates were 98% (88–99%) for EX0, 73% (59–84%) for EX2, and 71% (56–82%) for EX5. Only EX0 did not result in significant difference in retention rate at 24 M when compared with baseline but showed a significant higher retention rate when compared with those of EX2 and EX5 (p = 0.001). Conclusion Adding proanthocyanidins to the adhesive solution jeopardized the retention of composite resins restorations in non-carious cervical lesions after 24 months. Clinical relevance In spite of being user-friendlier than when used separately, the incorporation of proanthocyanidins into the adhesive solution impairs the longevity of composite restorations.

The journal of adhesive dentistry, 2016Co-Authors: André Mattos Brito Souza, Nadine Luísa Guimarães Albuquerque, Juliano Sartori Mendonça, Lidiany Karla Azevedo Rodrigues, Sérgio Lima SantiagoAbstract:PURPOSE To evaluate the use of oxalic acid in restorations of noncarious cervical lesions. MATERIALS AND METHODS Twenty volunteers of both sexes between 24 and 55 years old, with at least two lesions that were restored with the techniques to be evaluated, were selected. Ninety teeth were randomly divided into two groups: group 1, two-Step Etch-and-rinse adhesive technique (control) and group 2, pretreatment with oxalic acid followed by the application of a two-Step Etch-and-rinse adhesive system. The adhesive system used was XP Bond (Dentsply) and the restorative composite resin was Durafill (Heraeus Kulzer). A modified USPHS method was employed for the clinical evaluation, taking into account the following criteria: retention (R), marginal integrity (MI), marginal discoloration (MD), postoperative sensitivity (S), caries (C), and anatomic form (AF). Clinical assessments were conducted by two examiners at baseline and after 6 months, 1 and 2 years. RESULTS After two years, the results of clinically satisfactory restorations (Alpha and Bravo) obtained for the control and experimental groups were: R (90.9%/93.33%), MI (100%/100%), MD (100%/100%), S (100%/100%), C (100%/100%), AF (100%/100%). CONCLUSION Over a 2-year period, the use of oxalic acid as an agent of dentin pretreatment did not influence the clinical performance of restorations in noncarious cervical lesions.

Clinical effectiveness of contemporary adhesives: A systematic review of current clinical trials
The Journal of Prosthetic Dentistry, 2006Co-Authors: Marleen Peumans, Paul Lambrechts, J. De Munck, K.l. Van Landuyt, P. Kanumilli, B. Van MeerbeekAbstract:Objectives The purpose of this paper was to review current literature on the clinical effectiveness of contemporary adhesives when used to restore cervical non-carious class-V lesions. Restoration retention in function of time was recorded in order to find out if adhesives with a simplified application procedure are as clinically effective as conventional three-Step adhesives. Data Sources Literature published from January 1998 up to May 2004 was reviewed for university-centred clinical trials that tested the clinical effectiveness of adhesives in non-carious class-V lesions. Restoration-retention rates per adhesive reported in peer-reviewed papers as well as IADR-AADR abstracts and ConsEuro abstracts were included and depicted as a function of time in graphs for each of the five adhesive classes (three- and two-Step Etch-and-rinse adhesives, two- and one-Step self-Etch adhesives, and glass ionomers). The guidelines for dentin and enamel adhesive materials advanced by the American Dental Association were used as a reference. Per class, the annual failure rate (%) was calculated. Kruskal–Wallis analysis and Dwass–Steel–Chritchlow–Fligner pairwise comparisons were used to determine statistical differences between the annual failure percentages of the five adhesive categories. Results Comparison of retention of class-V adhesive restorations as a measure to determine clinical bonding effectiveness of adhesives revealed that glass ionomers most effectively and durably bond to tooth tissue. Three-Step Etch-and-rinse adhesives and two-Step self-Etch adhesives showed a clinically reliable and predictably good clinical performance. The clinical effectiveness of two-Step Etch-and-rinse adhesives was less favourable, while an inefficient clinical performance was noted for the one-Step self-Etch adhesives. Significance Although there is a tendency toward adhesives with simplified application procedures, simplification so far appears to induce loss of effectiveness. Clinical performance can be correlated with, and predicted by, appropriate types of laboratory study.— Reprinted with permission of The Academy of Dental Materials.

Hydrolytic stability of three-Step Etch-and-rinse adhesives in occlusal class-I cavities
Clinical oral investigations, 2012Co-Authors: Jan De Munck, Atsushi Mine, Marcio Vivan Cardoso, Kirsten Van Landuyt, Anne Katrin Lührs, André Poitevin, Masao Hanabusa, Takuo Kuboki, Bart Van MeerbeekAbstract:Objectives A dental adhesive without small and hydrophilic monomers such as 2-hydroxyethyl methacrylate (HEMA) and triethylene glycol dimethacrylate (TEGDMA) would be beneficial in order to avoid contact allergies. However, these monomers are important to increase infiltration and polymerization of the adhesive. Therefore, the purpose of this study was to evaluate the bonding effectiveness and bond durability of a more hydrophobic and biocompatible adhesive as compared to a conventional three-Step Etch-and-rinse adhesive.

Clinical effectiveness of a one-Step self-Etch adhesive in non-carious cervical lesions at 2 years.
Clinical oral investigations, 2011Co-Authors: R Banu Ermis, Jan De Munck, Marcio Vivan Cardoso, Kirsten Van Landuyt, Bart Van Meerbeek, Marleen PeumansAbstract:A 2-year randomized, controlled prospective study evaluated the clinical effectiveness of a one-Step self-Etch adhesive and a “gold-standard” three-Step Etch-and-rinse adhesive in non-carious Class-V lesions. The null hypothesis tested was that the one-Step self-Etch adhesive does perform clinically equally well as the three-Step Etch-and-rinse adhesive. A total of 161 lesions in 26 patients were restored with Clearfil AP-X (Kuraray). The restorations were bonded either with the “all-in-one” adhesive Clearfil S3 Bond (Kuraray) or with the three-Step Etch-and-rinse adhesive Optibond FL (Kerr). The restorations were evaluated at baseline and after 6 months, 1 and 2 years, regarding their retention, marginal adapation, marginal discoloration, caries occurrence, preservation of tooth vitality and post-operative sensivity. Retention loss, severe marginal defects and/or discoloration that needed intervention (repair or replacement) and the occurrence of caries were considered as clinical failures. The recall rate at 2 years was 93.8%. Only one Clearfil S3 Bond restoration was lost at the 2-year recall. All other restorations were clinically acceptable. The number of restorations with defect-free margins decreased severely during the 2-year study period (to 6.7% and 25.3% for Clearfil S3 Bond and Optibond FL, respectively). The Clearfil S3 Bond restorations presented significantly more small marginal defects at the enamel side than the Optibond FL restorations (Clearfil S3 Bond: 93.3%; Optibond FL: 73.3%; p = 0.000). Superficial marginal discoloration increased in both groups (to 53.3% and 36% for Clearfil S3 Bond and Optibond FL, respectively) and was also more pronounced in the Clearfil S3 Bond group (p = 0.007). After 2 years, the simplified one-Step self-Etch adhesive Clearfil S3 Bond and the three-Step Etch-and-rinse adhesive Optibond FL were clinically equally successful, even though both adhesives were characterized by progressive degradation in marginal integrity. Clearfil S3 Bond exhibited more small enamel marginal defects and superficial marginal discolorations.

A 13-year clinical evaluation of two three-Step Etch-and-rinse adhesives in non-carious class-V lesions
Clinical oral investigations, 2010Co-Authors: Marleen Peumans, Jan De Munck, Kirsten Van Landuyt, André Poitevin, Paul Lambrechts, Bart Van MeerbeekAbstract:This 13-year randomized clinical trial compared the clinical effectiveness of two three-Step Etch-and-rinse adhesives in combination with a hybrid, stiffer composite versus a micro-filled, more flexible composite. The influence of composite stiffness on the clinical performance of one of the adhesives was assessed as well. One hundred and forty-two non-carious cervical lesions were restored with composites with contrasting stiffness. Seventy-one patients randomly received two cervical restorations placed following two out of three adhesive procedures: (1) the three-Step Etch-and-rinse adhesive Permaquick applied with the stiff micro-hybrid composite Amelogen Hybrid (PMQ-H, Ultradent), (2) Permaquick applied with the more flexible micro-filled Amelogen Microfill (PMQ-M, Ultradent), or (3) the “gold-standard” three-Step Etch-and-rinse adhesive Optibond FL applied with the micro-hybrid composite Prodigy (OFL-P, Kerr). The restorations were evaluated after 6 months, 1, 2, 3, 5, 7, and 13 years of clinical service regarding their retention, marginal integrity and discoloration, caries occurrence, preservation of tooth vitality, and post-operative sensitivity. Retention loss, severe marginal defects, and/or discoloration that needed intervention (repair or replacement) and the occurrence of caries were considered as clinical failures. The recall rate at 13 years was 77%. Bond degradation after 13 years was mainly characterized by a further increase in the presence of small but clinically acceptable marginal defects and superficial marginal discoloration. Twelve percent of the OFL-P restorations were clinically unacceptable. In the PMQ group, 22% of the PMQ-M restorations and 26% of the PMQ-H restorations needed repair or replacement. Regarding the clinical failure rate, Optibond FL scored significantly better than Permaquick (McNemar; p = 0.015). No statistically significant differences were found between the micro-filled and the hybrid composite for each of the parameters evaluated (McNemar, p > 0.05). After 13 years of clinical functioning, the clinical effectiveness of the three adhesive/composite combinations remained highly acceptable.

bonding effectiveness and interfacial characterization of a hema tegdma free three Step Etch rinse adhesive
Journal of Dentistry, 2008Co-Authors: Atsushi Mine, Jan De Munck, Kirsten Van Landuyt, André Poitevin, Takuo Kuboki, Paul Lambrechts, Yasuhiro Yoshida, Kazuomi Suzuki, Bart Van MeerbeekAbstract:Summary Objectives Small and hydrophilic monomers as HEMA and TEGDMA can easily penetrate human tissues. For biocompatibility issues it is therefore better to avoid such monomers in dental adhesive formulations. The purpose of this study was (1) to determine the micro-tensile bond strength (μTBS) to enamel/dentin of a HEMA/TEGDMA-free three-Step Etchr the μTBS to dentin was however significantly lower (p Conclusions The new three-Step adhesive cmf Adhesive System showed indications of good bonding effectiveness, certainly to enamel and only significantly lower to dentin, when compared to the gold-standard adhesive. The latter may be related to the adapted HEMA/TEGDMA-free formulation and the somewhat lower mechanical properties.
