the aim of this study was to determine the microleakage at the cervical margin of the class II composite resin syntac with and without a cervical amalgam base and to compare microleakage restoration at the occlusal margins of restorations and inferface of amalgam and composite.68 extracted sound permanent premolar were used.68 class II slot cavities were prepared in these teth.the teeth were ra...

Purpose: This study aimed to compare the antibacterial effect and microleakage of two types fissure sealants; Beautisealant Embrace wet Bond. Materials Methods: for evaluation effect, 30 saliva samples were obtained sent microbiology laboratory where streptococcus mutans isolated both materials was detected by agar diffusion method. For test extracted sound permanent molars obtained. Two groups...

OBJECTIVE To assess the efficacy of two sealants to preserve the apical seal after root canal preparation and cementation of posts at 24 h or 72 h after endodontic treatment. STUDY DESIGN Sixty human single-root teeth were instrumented and obturated using lateral compaction technique with EndoFill [30] or AH-Plus) [30] and were prepared in one of three ways, leaving a 3 mm gutta percha remnan...

The aim of this study is to evaluate the microleakage a self-adhesive cement recently marketed Rely X U100 (3M ESPE). Thirty roots of bovine teeth with 14 mm long were restored with self-adhesive cement and Glassix fiber post DC3 (FGM). Roots were randomly divided into three groups (n=10) according to the technique of placement of the cementing agent: G1 - Centrix syringe; G2 - Lentulo drill an...

Microleakage presents a major challenge to the success of all restorations placed in the oral cavity, resulting in postoperative sensitivity, pulpal irritation, and secondary caries formation. The objective of this study was to evaluate the effects of an adhesive cavity liner under amalgam restorations in primary teeth. Sixty class V amalgam restorations were placed on the buccal and/or lingual...

The objective of this study was to evaluate the effects of diode laser and a desensitizing dentifrice on dentin permeability. Fifty-two root dentin fragments were obtained (5 × 5mm) and treated with 24% EDTA gel. The samples were divided into 4 groups (n = 13): G1, control (no treatment); G2, diode laser (λ = 908 nm, 1.5 W, continuous mode, 20s); G3, application of abrasive dentifrice for 1 min...

OBJECTIVE One of the principle purposes of root canal obturation is to obtain hermetic sealing of the root canal system. According to the development of technology, many materials are now used in root canal filling. An in vitro dye leakage study was performed to evaluate the apical sealability of White-colored Mineral Trioxide Aggregate (WMTA) and Gray-colored Portland Cement (GPC) when used al...
