Changes in the dynamic Young's modulus under flexure of self-cured and light-cured composite resins during setting were demonstrated to reflect accurately the condition of the curing composite resins. The rate of stiffness increase during setting varied considerably with the product, and the light-cured composite resins generally showed a faster rate of increase of stiffness. In the initial stage, the Young's moduli were very low, especially for the self-cured composite resins. This accounts for the damage (adhesion disruption and cross-linking interruption) that can be inflicted on a freshly

ABSTRACT:Composite resins are currently the most popular restorative material in dentistry. This is due to good aesthetics and maximum conservation ability. Behind these advantages, there are disbenefits of composite resin materials, such as polymerization shrinkage, which can lead to restoration failure. Various attempts have been investigated to reduce the shrinkage incidence of composite resins, one of which is the technique of placing the restorative material into the cavity. The restoration filling technique is recognized as a significant factor in shrinkage stress. By using a special fil

Summary Polymerization contraction of composite resins has been one of the most extensively studied phenomena in dentistry in recent years. Initial polymerization by low intensity light followed by polymerization high intensity light improves marginal adaptation of composite in tooth cavities. A number of studies have verified that less marginal leakage and lower marginal index (MI) exist in relation to standard polymerization (continuous high intensity light). The aim of the study was to quantittively evaluate the bond of composite materials to dentin and determine the MI values in dentin aft

Increasing numbers of resin-based dental restorations have been placed over the past decade. During this same period, the public interest in the local and especially systemic adverse effects caused by dental materials has increased significantly It has been found that each resin-based material releases several components into the oral environment. In particular, the comonomer triethyleneglycol di-methacrylate (TEGDMA), and the 'hydrophilic' monomer, 2-hydroxy-ethyl-methacrylate (HEMA), are leached out from various composite resins and 'adhesive' materials (e.g., resin-modified glass-ionomer ce

Abstract In general excellent results cannot be guaranteed when using resin-based composites for posterior restorations. This is due to polymerization shrinkage which can still be regarded as the primary negative characteristic of composite resins. A review of available literature regarding the polymerization process, its flaws, and suggested strategies to avoid shrinkage stress was conducted. Several factors responsible for the polymerization process may negatively affect the integrity of the tooth-restoration complex. There is no straightforward way of handlling adhesive restorative material

Abstract Currently, many composite materials have been used in the filling of access openings for screw-retained implant prosthesis. The main disadvantage of these materials is the compromise in esthetics that they place on the implant crown. An additional disadvantage is leakage of bacterial contaminants around traditional light-cured composites placed in the screw access hole. This article introduces a technique that uses opaqueing composites and the expansion properties of panacea (Zeza Inc, Chester, NY) resin to help remedy these problems. The fabrication of the silicone obturator is expla

SUMMARY The bulk-filling of deep, wide dental cavities is faster and easier than traditional incremental restoration. However, the extent of cure at the bottom of the restoration should be carefully examined in combination with the polymerization contraction and gap formation that occur during the restorative procedure. The aim of this study, therefore, was to compare the depth of cure, polymerization contraction, and gap formation in bulk-fill resin composites with those of a conventional resin composite. To achieve this, the depth of cure was assessed in accordance with the International Org

Composite resin is a caries filling material. Generally, dentists choose this type of resin as a restoration material because this material has a high compressive strength. There are several factors that influence the compressive strength of composite resins, including beverages consumed such as coffee. This study aims to determine the difference in the compressive strength of the composite resin with Sidikalang coffee immersion in 9 hours, 27 hours and 54 hours immersion time. This type of research is experimental laboratories with posttest only control group design. The research sample was c

SUMMARY This article describes the clinical technique of using the transparent plastic tips of the LM-Contact Former system for obtaining tight proximal contacts in direct Class II composite resin restorations using noncontoured circumferential matrix bands. With this technique, the composite resin is pressed with the tip, which adapts intimately to the walls of the proximal box. Moreover, the total working time is reduced by filling the cavity, which remains after removing the transparent tip, with a bulk-fill flowable resin-based composite.

Abstract The aim of this study was to investigate the effect of light intensity on polymerization shrinkage of resin composites. The five materials tested were Lite-Fil (A) (LFA), Lite-Fil (P) (LFP), Z100, Palfique, (PAL) and Tetric (TRC). Two types of measurements were made to determine the effects of environmental temperature and light intensity. Results were analyzed by two-way analysis of variance (ANOVA) and Newman-Keuls procedure at (P<0.05). The changes in temperature and/or light intensity strongly affected composite shrinkage. The amount of shrinkage for LFP at 100% light intensity

Background: Composite resin is filling material that used in dentistry fieldbecause of good aesthetic. Use of fiber as reinforced composite resin (FRC)begins to be developed because it has a lot of functions, such as increasestrength, stiffness, material hardness from fracture, and decrease shrinkage.Fiber composite resin has syntetic characteristic and needs chemical processalso has an expensive price. Therefore, natural fiber is easier to find, cheaper and can be developed as an alternative substitute of syntetic fiber. One of the natural alternative is sisal fiber. This study aims to know t

Root-end filling materials are commonly used following endodontic surgical procedures; however, their effect on adjacent soft tissues is poorly understood. We predict that, due to the differences in their chemical composition, these materials will have profoundly different effects on the survival and differentiation of fibroblasts. Many of the root-end filling materials examined were initially cytotoxic to both PDL and gingival fibroblasts in co-culture experiments; however, this was reduced after the materials were washed in either mineral trioxide aggregate (MTA) or hybrid ionomere composite
