OBJECTIVE To determine whether an amorphous calcium phosphate (ACP)-containing adhesive has an acceptable level of shear bond strength to be used as an orthodontic adhesive. MATERIALS AND METHODS Sixty extracted premolars were randomly divided into three groups for orthodontic bonding. Group 1 used a composite resin adhesive (Transbond XT), group 2 was bonded with an ACP-containing adhesive (...

This study evaluated the simulated localized wear of resin luting cements for universal adhesive systems using different curing modes. Five resin luting cements for universal adhesive systems were evaluated and subsequently subjected to wear challenge in a Leinfelder-Suzuki wear simulation device. Overall, 20 specimens from each resin luting cement were photo-cured for 40 s (dual-cure group), a...

An "adhesive bridge" technique permitting the chairside replacement of missing single anterior teeth was evaluated over a 19-month period in 18 subjects. Results indicated that "adhesive bridges" offered definite advantages in ease of construction, oral tissue compatability, and esthetics, particularly to the Navy dentist without access to laboratory support. These advantages were offset to a c...

Purpose: This study evaluated the influence of surface treatments on the microtensile bond strength between a glass fiber post surface and resin cements. Methods: Forth-five posts (Reforpost, Angelus, Londrina, PRBrazil) were assigned to three groups with different surface treatment: Group 1: No treatment and silane application only (G1); Group 2: immersion in 96% ethyl alcohol for 10 minutes f...

Aim: To evaluate the long-term post push-out bond strength to dentin, water sorption, solubility and swelling of conventional and self-adhesive dual-cure resin cements. Methods: Forty-eight bovine roots were prepared for fiber post cementation with RelyX ARC and RelyX U100. According to resin cement and storage time (24 h and 6 months), 4 groups were assessed using the push-out test. Water sorp...

Aims and Objectives To evaluate the influence of indirect chair-side polymerization of resin composite cores on the fracture resistance of overlaying IPS e.max Press crowns. Materials and Methods Root canals of 60 extracted premolars were prepared to receive #2 fiber posts after the crowns were sectioned 2 mm above the cervical line. In Groups 1-3 (n = 10 each), posts were luted to the prepar...

STATEMENT OF THE PROBLEM Structural integrity and dimensional stability are the key factors that determine the clinical success and durability of luting cements in the oral cavity. Sorption and solubility of self-adhesive resin luting cements in food-simulating solutions has not been studied sufficiently. PURPOSE This study aimed to compare the sorption and solubility of 2 conventional and 2 ...

Objective: To evaluate the influence of immediate dentin sealing (IDS) and mechanical methods for removing thetemporary cement on bond strength between resin cements. Material Methods: Bovine incisorswere ground until exposure divided according to two factors: “dentin surface treatment”’ - cleaningwith manual dental excavator (DE), with Robinson bristle brush pumice paste (PP) or IDS applicatio...
