Special Issue Information

Dear Colleagues,

This Special Issue, “Advances in Dental Adhesive Technology”, explores new and improved solutions in dental adhesive technology, from the composition of materials to the treatment of tooth substrate and material–tissue interactions, the effectiveness of clinical techniques and the longevity of adhesively bonded restorations. The concept of adhesion continues to evolve from an acid-etch to a self-etch strategy, taking into consideration the complexities of enamel and dentine in normal and pathological conditions. The latest additions to the heterogeneous group of adhesive systems are the universal adhesives, marketed for use with different application protocols on tooth tissues and with materials for indirect restorations. Recent adhesive systems contain 10-MDP, a monomer with a confirmed ability to chemically bond to hydroxyapatite, whose role in long-term bonding has not yet been fully elucidated. Different dentine treatment options are investigated for improved resin–dentine interaction, polymerization, and bond strengths as well as the retarded or mitigated biodegradation of resin-dentine bonds due to hydrolysis and enzyme-mediated degradation. To this effect, various clinical techniques have been tested, such as multi-step adhesive application and additional hydrophobic layering. The repair of esthetic restorations, especially the interface between the old and the new restoration, requires further scrutiny of adhesive technology for optimized and predictable bonding effectiveness.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

(1) Background: The aim of this in vitro study was to evaluate the micro-tensile bond strength (µ-TBS) of universal adhesives to primary tooth dentin after different storage periods. (2) Methods: Dentin of 100 extracted primary molars was exposed. Dentin surfaces were bonded with six universal adhesives (Adhese®Universal [AU], All-Bond Universal® [ABU], G-Premio Bond [GPB], iBond®Universal [IBU], Prime&Bond active™ [PBa], and Prime&Bond®NT as control [PBN]) and restored with a resin composite build-up (Filtek™ Z250). After 24 h, 6 months, and 12 months of water storage, specimens were cut into sticks, and µ-TBS was measured and analyzed using one-way ANOVA (p < 0.05) for normal distributions and the Mann–Whitney U-test (p < 0.05) for non-normal distribution. Pretesting failures were recorded as 0 MPa. Fracture modes were analyzed under a fluorescence microscope; interfaces were visualized with SEM/TEM. (3) Results: Compared with the reference group (PBN: 32.5/31.2 MPa after 6/12 months), two adhesives showed a significantly higher bond strength after 6 months (AU: 44.1 MPa, ABU: 40.9 MPa; p < 0.05) and one adhesive after 12 months (AU: 42.9 MPa, p < 0.05). GPB revealed significantly lower bond strengths in all storage groups (16.9/15.5/10.9 MPa after 24 h/6 months/12 months; p < 0.05). AU and IBU did not suffer pre-test-failures [PTF]. (4) Conclusions: After 12 months, PBN, IBU, AU, and GPB showed significantly lower results compared ithw initial µ-TBS, whereas AU revealed the highest µ-TBS and no PTF. Full article
