Purpose: To evaluate the effects of etching mode (self-etch and etch-and-rinse) on acid-base resistant zone (ABRZ) formation at the resin cement/enamel interface and enamel etching pattern, as well as the effects of thermocycling (0, 5000, and 10,000 cycles) on the enamel microshear bond strength (μSBS) mediated by dual-cure resin cements (DCRC).

Materials And Methods: Two DCRC were used in 4 groups: Panavia V5 in self-etch (V5NE) and etch-and-rinse mode (V5E); and Estecem II in self-etch (ENE) and etch-and-rinse mode (EE). For ABRZ observation, the bonded interface was subjected to a demineralizing solution.

Article Synopsis
  • Tooth loss causes various oral issues, and while many treatments exist, none can replace a missing tooth with a completely new natural one.
  • Research in tissue engineering has focused on developing methods to regenerate whole teeth, utilizing animal models to study this process.
  • Results indicate that over 58% of the test animals experienced successful tooth eruption after implanting engineered tooth germs, suggesting that whole tooth regeneration is feasible; however, significant challenges remain before this can be tested in humans.

Objectives: to evaluate the probability of survival and failure modes of lithium-disilicate, feldspathic-ceramic, and resin-nanoceramic anterior veneers cemented on dentin analog substrates after sliding-contact step-stress accelerated life testing (SSALT).

Methods: A virtual incisor tooth preparation was produced with a reduction of 1.5mm at the incisal edge and of 0.

Objective: To evaluate the influence of the degree of dentin moisture on interfacial ultramorphology and bond strength (μTBS) of universal adhesives.

Materials And Methods: Futurabond U (FBU), Scotchbond Universal (SBU), Adhese Universal (ADU), and Prime&Bond active (PBA) were used. After acid-etching, moist or over-dried dentin surfaces were tested.

Purpose: To evaluate the bond strength to dentin produced by experimental adhesives formulated with an elastomeric methacrylate monomer (EMM) and an alternative initiator system based on a Thioxanthone derivative (QTX).

Materials And Methods: A self-etching primer was used. For the bonding resin, a model adhesive (G1) was formulated containing bis-GMA/TEG-DMA/HEMA (co-monomeric blend) + CQ/EDAB (initiator system).

Objective: To test the effects of different adhesive protocols and silane application on the adhesive durability to a Lithium Disilicate reinforced glass ceramic.

Methods: Forty disks of 13 mm diameter (E.max Press) were used.

Purpose: To evaluate the microtensile bond strength (μTBS) of a bulk-fill low-stress resin-based composite to dentin from gingival walls of Class II MOD cavities.

Materials And Methods: Class II MOD cavities were prepared in 44 human molars with the distal and mesial proximal boxes 4 and 6 mm deep, respectively. Eight experimental groups (n = 11) were obtained by a factorial design including 1.
