Objectives Bonding of fiber posts to intracanal dentin is challenging in the clinical setting. This study aimed to compare the effect of self-adhesive and separate etch adhesive dual cure resin cements on the bond strength of fiber post to dentin at different parts of the root. Materials and Methods This in-vitro experimental study was conducted on 20 single-rooted premolars. The teeth were d...

OBJECTIVE The purpose of this study was to evaluate the influence of Er:YAG laser irradiation on shear-bond strength of self-adhesive resin cements to dentin. BACKGROUND DATA Different laser-irradiation settings are used for dentin-surface pretreatment, which may affect the bond strength of resins. METHODS Fourty-five extracted third molars were selected, sectioned in a mesiodistal directio...

OBJECTIVE The purpose of this study was to evaluate, by shear bond strength (SBS) testing, the influence of different types of temporary cements on the final cementation using conventional and self-etching resin-based luting cements. MATERIAL AND METHODS Forty human teeth divided in two halves were assigned to 8 groups (n=10): I and V (no temporary cementation); II and VI: Ca(OH)2-based cemen...

OBJECTIVE The aim of this study was to compare the resistance to vertical root fracture of root-filled teeth restored with four different fiber-reinforced composite (FRC) post systems and two types of dual-cured resin luting agents. MATERIALS AND METHODS Ninety extracted human maxillary central incisors were selected and decoronated to obtain a standardized root length of 14 mm. After root ca...

The objective of this study was to investigate the effect of various luting cement systems on bond strength of fibre-reinforced posts to root canal dentine. 40 extracted single rooted sound premolar teeth were root filled, decoronated and randomly divided into four groups. Fibre posts, AesthetiPlusTM (Bisco,Inc. Schaumburg, IL, USA) were cemented using four luting cements: Group A (control): El...

OBJECTIVES Computer-aided design (CAD) and manufacturing (CAM) allows the milling of high strength zirconia fixed partial dentures (FPD), however bonding to an inert ZrO(2) ceramic surface may effect the marginal integrity of the FPDs. The aim of this investigation was to evaluate the marginal adaptation of zirconia FPDs at the interfaces between zirconia, cement, and tooth. METHODS 32 3-unit...

OBJECTIVES To evaluate microleakage and marginal gaps in full cast crown restorations bonded with six different types of cementing agents. METHODS Sixty non-carious human premolars and molars were prepared in a standardized manner for full cast crown restorations. The mesial and distal margins were located in dentin, while the vestibular and palatal/lingual margins were located in enamel. Cro...

PURPOSE This study was performed to evaluate shear bond strength (SBS) between three dual-cured resin cements and silica coated zirconia, before and after thermocycling treatment. MATERIALS AND METHODS Sixty specimens were cut in 15 × 2.75 mm discs using zirconia. After air blasting of 50 µm alumina, samples were prepared by tribochemical silica coating with Rocatec™ plus. The specimens were ...
