This study examined the surface staining mechanism of a photopolymerized composite by coffee, oolong tea, and red wine. Dental was subjected to an experimental 24-hour cycle: 17-hour immersion in artificial saliva solution containing 0.3% mucin followed 7-hour or After one, two, four weeks, digital images were analyzed grayscale mode with imaging analyzer. Specimens polished but not immersed used as baseline measurement for color change. Additionally, effects mechanical brushing...
The purpose of this study was to evaluate the short-term µTBS (Micro-tensile bond strength) and microscopic (SEM TEM) observation four recent adhesives. One adhesive an experimental step-less 1-step system (LLB-2, Tokuyama Dental), which is all-in-one without light-curing step in application process. other two were self-adhering light-cured flowable composite resin systems FLD (Fusio Liquid Dentin, Pentron Clinical Technologies) VF (Vertise Flow Dental Restorative Materials, Kerr...
Abstract The purpose of this study was to evaluate the morphological appearance resin‐dentin interface produced by 1‐step adhesive systems in order classify them, using TEM. It hypothesized that all interfaces each show characteristics similar conventional self‐etching system rather than etch‐and‐rinse system. flattened dentin surfaces were subjected bonding treatment either a 2‐step adhesive: single bond, mega unifil bond; or Prompt L‐Pop, absolute, xeno CF, AQ one‐up bond F, G and SSB‐200....
Why Is This Important?There are often different interpretations by clinicians, manufacturers, and researchers regarding what defines a bioactive material.This has led to confusion amidst varying claims individual stakeholders.Unlike the more traditional passive materials, materials designed elicit desired therapeutic or beneficial response.Such have been described as releasing ions molecules produce an antimicrobial, remineralizing, regenerating effect within living organism.Given...
The purpose of this study was to evaluate the optical properties--not only translucency but also colours--of opaque-shade resin composites. CIELAB parameters (L*, a* and b*) disks A2 opaque (OA2) shades Charisma (Heraeus-Kulzer), Solare (GC) Filtek Supreme (3M) were evaluated on backings black, white material itself calculate parameter (TP) colour differences (delta E*) between OA2. A two-way analysis variance (anova) for TP indicated a less statistically significant value in OA2 shade than...
The tooth interface with resin-modified glass-ionomer cements (RM GICs) is poorly understood. This study examined the interface, especially dentin. Cervical cavities in extracted teeth were restored Fuji II LC, Vitremer, Photac-Fil, or a conventional GIC, Cap II. Fluorescent dye was placed pulp chambers for 3 hrs before specimens sectioned. Examination of tooth/material confocal microscope showed that uptake by restoration varied among materials. A "structureless", non-particulate,...
The dimensional change, including hygroscopic of adhesive dental materials is a clinically important topic, since excessive changes could cause debonding from tooth structure. water balance glass-ionomer cements arises mainly their sensitivity to the environment; depending on surroundings, they can gain or lose water, either which be potentially damaging. These effects become less noticeable as cement ages. maturity newer resin-modified and responses in moisture are unknown. Using confocal...
Glass-ionomer cements (GICs) are regarded as aqueous gels made up of polyalkenoic acid salts containing ion-leachable glass fillers. The consequence water permeation across the GIC-dentin interface is unknown. This study used SEM, field-emission/environmental SEM (FE-ESEM), and TEM to examine ultrastructure GIC-bonded moist dentin. Dentin surfaces bonded with 6 auto-cured GICs were examined along fractured interfaces. Additional specimens 3 mm away from interfaces controls. revealed...
This study evaluated color and translucency changes caused by light curing resin composite materials.The CIELAB parameters (L*, a* b*) of disks A2 opaque shades Charisma (Heraeus-Kulzer), Solare (GC) Filtek Supreme (3M) were on the backings black, white material itself both before after to evaluate (by means calculating deltaE* parameter, respectively).Solare showed significantly smaller during than Charisma; however, value all products/shades was still in clinically unacceptable range....
To evaluate the anatomical relationship between roots of mandibular second molars and inferior alveolar nerve (IAN) in relation to risk potential injury during root canal treatment.Cone-beam computed tomography (CBCT) images from patient record database at a dental hospital were selected. The anonymized CBCT reconstructed examined three planes (coronal, axial sagittal) using 3D viewing software. each apex IAN was evaluated by measuring horizontal vertical distances coronal sections, actual...
