The development of orthodontics has improved thanks to the introduction of adhesives which are physically and chemically akin to tooth enamel and brackets. These materials often fall short of the required durability standards. The objective was to evaluate the real strength of the adhesives and to introduce a proprietary device, generating multiple vectors of strength between dental brackets an...

AIM To evaluate the capability to reinforce tooth structure and sealing ability of temporary filling materials in premolars with MOD cavities. The hypothesis is that temporary filling materials can concomitantly prevent microleakage and increase fracture resistance. MATERIALS AND METHODS Premolars received root canal treatment and MOD cavities. Cavities were restored with non- eugenol cement ...

Glass Ionomer Cement (GIC) is one of the most popular materials among the available dental restorative materials. They have desirable properties like direct adhesion to the tooth structure, thermal compatibility [1] and good biocompatibility [2,3]. Despite these advantages, brittleness, low tensile and flexural strengths have limited their use only to certain low stress-bearing sites. As such, ...

To evaluate the effect of a dentin adhesive on sclerotie dentin, contraetion gap width and shear bond strength were measured, Dent{n cavity wall was pretreated with an experimental dentin bonding system w{th and without a dentin primer, or with a commercial dentin bonding system. In the experimental dentin bonding groups, contraction gap width of sclerotic dentin was signifieantly smaller than ...

In this study, the intra- and interobserver reliability of the Semmes-Weinstein monofilaments (SWMFs) was determined in the hands of 15 patients with Charcot-Marie-Tooth disease. In addition, the amount and distribution of sensory loss in the hand, and the relation between sensory loss, intrinsic muscle strength, and hand dexterity was explored in 45 patients. SWMF testing had good intra- and i...

BACKGROUND Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) is applied for remineralization of early caries lesions or tooth sensitivity conditions and may affect subsequent resin bonding. This in vitro study investigated the effect of CPP-ACP on the shear bond strength of dental adhesives to enamel. MATERIALS AND METHODS Sixty extracted human molar teeth were selected and randomly...

ARTICLE INFO Abstract Article History: Received 2 August 2015 Accepted 2 November 2015 Statement of Problem: There is no enough published data about the shear bond strength of resin modified glass ionomer adhesives on caries-affected primary tooth dentin excavated using minimally invasive systems. Objectives: To evaluate the shear bond strength of 2 different adhesives (one resin modified glass...

PURPOSE The aim of this study was to determine whether the push-out bond strengths between the radicular dentin and fiber reinforced-composite (FRC) posts with various resin cements decreased or not, according to the coronal, middle or apical level of the root. MATERIALS AND METHODS FRC POSTS WERE CEMENTED WITH ONE OF FIVE RESIN CEMENT GROUPS (RELYX UNICEM: Uni, Contax with activator & LuxaCo...

BACKGROUND Lack of seal and adhesion between the final restoration and tooth structure adversely affects the results of root canal treatment. Lots of adhesive bonding agents are marketed to overcome this deficiency and achieve successful restoration. So the study compares and evaluates the micro shear bond strength of coronal dentin and pulp chamber dentin using three different generation denti...

BACKGROUND To compare the microtensile bond strength of resin cements to enamel and dentin and to determine the type of bond failure using stereomicroscope. MATERIALS AND METHODS In this in-vitro study 40 teeth were embedded in acrylic resin and divided into two main groups i.e., Group A for enamel and Group B for dentin. Each group is again subdivided into four subgroups, which are as follow...
