What is a "compomer"? (1/59)

"Compomers" are recently introduced products marketed as a new class of dental materials. These materials are said to provide the combined benefits of composites (the "comp" in their name) and glass ionomers ("omer"). Based on a critical review of the literature, the author argues that "compomers" do not represent a new class of dental materials but are merely a marketing name given to a dental composite.  (+info)

Resin content in cement liquids of resin-modified glass ionomers. (2/59)

Qualitative and quantitative analyses were conducted on four kinds of resin-modified glass ionomer (RMGI) cement liquids, LC, LC II, LC III (hereinafter referred to as LCs) and VM, using HPLC and laser Raman spectroscopic methods. HPLC revealed that among the RMGI liquids LCs contain 31-32% HEMA (2-Hydroxyethyl methacrylate), and VM contains 18% of the same. The composition of RMGI cement liquids varied significantly between manufacturers. In Raman spectroscopic analyses, the spectra of liquids of various ratios of polyacrylic acid and HEMA were measured, and calculations were made on the peak intensity ratios of C=C stretch vibration to C=O stretch vibration, common in both HEMA and polyacrylic acid. The composition ratio of polycarboxylic acid to HEMA of commercial glass ionomer cements was assessed by the regression curve generated by a combination of peak intensity ratios and composition ratios. In addition, Raman spectroscopy was able to identity the differences in form of the methacryloyloxy group.  (+info)

The influence of configuration factors on cavity adaptation in compomer restorations. (3/59)

The effect of configuration factor (C-factor) on cavity adaptation was investigated in three compomer and one resin composite restorations. Eighty-four cylindrical dentin cavities (C-factor: approximately 2.5, 3.0 or 4.0) prepared on flat coronal dentin surfaces were filled with the materials in combination with their proprietary adhesive systems. Cavity adaptation was microscopically examined after 15 minutes storage in water at the top surface and at other four sites along the cavity walls. Additionally, indentation testing was performed for each material at 20 minutes and 24 hours after irradiation. Regression analysis revealed no relationship between C-factor and gap dimension in compomer restorations at any of the measuring sites, while a logarithmic relation was found only at the cavity floor of the composite fillings. All materials showed maturation of mechanical properties. The elastic component of the indentation was smaller in compomers than in the composite. It was concluded that C-factor had no influence on the cavity adaptation for compomer restorations. This might be due to reduced stress generation at the bonding interface caused by relatively low mechanical properties immediately after curing, less elasticity, and water absorption in compomers.  (+info)

The effect of primers on bond strength of polyacid-modified resin composites (compomers). (4/59)

This study evaluated the effect of primer on shear bond strength and marginal gaps of six new compomers immediately after light-activation. A resin-modified glass ionomer cement, a conventional glass-ionomer cement and a microfilled composite were used for comparison. The marginal gap widths of each of the four compomers and a microfilled composite used with the primer were significantly smaller compared with those used without the primer. The bond strength values of five compomers used with the primer were significantly higher than those used without the primer. The bond strength of conventional glass-ionomer was not affected by the primer (or the conditioner).  (+info)

Release and recharge of fluoride by restorative materials. (5/59)

This study investigated the release and recharge of fluoride by restorative materials. Resin-modified glass ionomers (RGIs), polyacid-modified composite resins (PMCRs) and resin composite containing fluoride were used for comparison of fluoride release. Non-fluoride-releasing resin composite was used as a control. The amounts of fluoride release from RGIs and PMCRs remarkably increased in the citrate-phosphate acid buffer compared with distilled water. The amounts of fluoride recharged in RGIs increased with the concentration of NaF solution, but those of PMCRs exposed to all concentrations of NaF solutions were less than 1.5 ppm. Neither resin composite containing fluoride and non-fluoride-releasing resin composite gave any evidence of recharge. RGIs and PMCRs affected by acid buffer solution could not recharge much fluoride even if they were immersed in the 1000 ppmF NaF solution. The results suggested that the matrix of RGIs and PMCRs functioned as a reservoir of fluoride, but the functions were lost by acid attack.  (+info)

An ex vivo assessment of resin-modified glass ionomer bonding systems in relation to ceramic bracket debond. (6/59)

This ex vivo study assessed three new resin-modified glass ionomer cements (Fuji ORTHO LC, Vitremer, and Dyract-Cem) in relation to ceramic bracket removal. It was hypothesized that the use of these cements would facilitate bracket removal and eliminate debond complications Eighty extracted premolar teeth were divided into four groups of 20 teeth and bonded with Intrigue brackets using each of the resin-modified cements (groups 1, 2, and 3), the control group 4 was bonded with Concise chemically-cured adhesive. The teeth were debonded by applying a shear load using an Instron universal testing machine. The mean force to debond was calculated for each group and each tooth was examined under the stereomicroscope to record the site of bond failure and the Adhesive Remnant Index (ARI). The results showed that the resin-modified cements were very effective at eliminating ceramic bracket debond problems. Bracket fracture was eliminated compared with a 40 per cent fracture rate with the control and the ARI scores were all reduced. The elimination of debond problems appears to be related to the significantly reduced (P < 0.001 using ANOVA and Tukey tests) mean and maximal debond forces compared with the control.  (+info)

Evaluation of the surface roughness of compomer by laser scanning microscopy. (7/59)

The purpose of this study was to evaluate the effect of alcoholic and low pH soft drinks on the surface roughness of compomer restorative materials. There were five tested materials and four immersion media. Specimens were immersed in test solutions for a 10-day period at a temperature of 37 degrees C. Measurement of the surface texture was carried out using a laser scanning microscope (a non-contact laser stylus tracing method). This was also used to produce the Laser Scanning Microscope Image (LSM Image). Specimens immersed in orange juice and whisky displayed higher values for Ra & Rz than specimens immersed in soft drinks and deionized water. LSM Image showed a difference between the control and the examined side, especially for specimens immersed in low pH soft drinks this could be due to the erosive effect of the media. Alcoholic and low pH soft drinks caused deterioration of the materials surface, which may lead to a clinically detectable rough and dull surface.  (+info)

Fatigue of restorative materials. (8/59)

Failure due to fatigue manifests itself in dental prostheses and restorations as wear, fractured margins, delaminated coatings, and bulk fracture. Mechanisms responsible for fatigue-induced failure depend on material ductility: Brittle materials are susceptible to catastrophic failure, while ductile materials utilize their plasticity to reduce stress concentrations at the crack tip. Because of the expense associated with the replacement of failed restorations, there is a strong desire on the part of basic scientists and clinicians to evaluate the resistance of materials to fatigue in laboratory tests. Test variables include fatigue-loading mode and test environment, such as soaking in water. The outcome variable is typically fracture strength, and these data typically fit the Weibull distribution. Analysis of fatigue data permits predictive inferences to be made concerning the survival of structures fabricated from restorative materials under specified loading conditions. Although many dental-restorative materials are routinely evaluated, only limited use has been made of fatigue data collected in vitro: Wear of materials and the survival of porcelain restorations has been modeled by both fracture mechanics and probabilistic approaches. A need still exists for a clinical failure database and for the development of valid test methods for the evaluation of composite materials.  (+info)

... is a compomer-based light-curing dental restorative with high fluoride release. It combines the benefits of glass ionomers and composites in one material with its special chemical composition of a polymer matrix and fillers.
The demand for esthetic restorative materials for the replacement of decayed or damaged tissue in the posterior teeth has increased significantly. The growing controversy about amalgam s mercury content is one of the forces behind this trend: There is increasing environmental concern about the use of mercury in a number of industries, including the dental materials industry. Many manufacturers of dry batteries and manufacturers of house paints are now producing mercury-free products. Mercury in amalgam restorations is present in a reacted compound form that is much less toxic than the elemental form. In spite of this, mercury content remains an issue for health and environmental reasons. Another force behind the trend away from amalgam is that many people perceive these restorations as unsightly. Finally, excessive tarnish and corrosion are problems with conventional amalgam formulations; however, high-copper-content alloys tend to perform better in this respect (Fig. 1).

A tube body includes an interior bore to carry a material flow into bone. The tube body includes a dispensing end having an opening communicating with the bore to dispense the material flow. One embodiment provides a cutting element, which extends in the opening to permit passage of the material flow and to sever the material flow in response to rotation of the tube body. Another embodiment deflects the dispensing end from the main axis of the tube body, to facilitate targeted introduction of flowable material, even when the access path does not align the tube body along the natural geometric axes of the treatment site. Another embodiment provides a connector having a rotating fitting, which releasably connects the tube body to a cement injecting tool. The rotating fitting allows the physician to rotate the injection nozzle assembly to control orientation and position in the treatment site, without rotating the associated injection tool itself.
Ionomers - Glass ionomers are tooth-colored materials made of a mixture of acrylic acids and fine glass powders that are used to fill cavities, particularly those on the root surfaces of teeth. Glass ionomers can release a small amount of fluoride that help patients who are at high risk for decay. Glass ionomers are primarily used as small fillings in areas that need not withstand heavy chewing pressure. Because they have a low resistance to fracture, glass ionomers are mostly used in small non-load bearing fillings (those between the teeth) or on the roots of teeth. Resin ionomers also are made from glass filler with acrylic acids and acrylic resin. They also are used for non-load bearing fillings (between the teeth) and they have low to moderate resistance to fracture. Ionomers experience high wear when placed on chewing surfaces. Both glass and resin ionomers mimic natural tooth color but lack the natural translucency of enamel. Both types are well tolerated by patients with only rare ...

Some of the major indications for electrosurgery are described and illustrated in the following sections.. Electrosurgery to Facilitate Placement of Direct Composite Materials. Tissue management during direct restorative procedures is an area where dentists can benefit greatly from electrosurgery. During cavity preparation, patients are almost always anesthetized. Nonetheless, delivery of a small amount of anesthesia into the soft tissue is recommended when a soft-tissue electrosurgical procedure is planned. For example, when interproximal electrosurgery is planned prior to matrix placement around a maxillary tooth, the interproximal tissues still might not be sufficiently numb from a vestibular infiltration. One solution is to administer 2% lidocaine with 1:50,000 epinephrine circumcoronally around the tooth that is being restored. Intrapapillary and marginal injections will blanch the tissue and gain soft-tissue anesthesia circumcoronally, preparing the patient for a number of ...

Tooth-colored fillings are a great way to restore cavities, replace metal fillings & brighten your smile. Call Dunwoody general dentist, Dr. Rodgers, today!
A:) While the U.S. Public Health Service issued a report in 1993 stating that there is no health reason not to use silver fillings (amalgam), more patients today are requesting "white" or tooth-colored composite resin fillings. Dr. Wolffs office uses tooth-colored fillings because they "bond" to the tooth structure, helping to strengthen a tooth that has been weakened by decay. In addition, they are more aesthetically appealing and can be less sensitive to varying temperatures. In cases where composite fillings cannot be used, a crown is usually necessary to provide overall satisfaction for the patient.. ...

Once the injured patient arrives at the hospital, its time for the surgical team to work its magic -- and theres a complex series of steps they take in surgery to ensure the severed limb can survive once its reattached. First theyll reattach the bone, using pins or wire to hold it together. Then specialists will restart blood flow by suturing the arteries and blood vessels. Next, surgeons begin the laborious process of reconnecting tendons, muscle tissue and nerves, although nerve reattachment can be saved for a later date. Finally, using grafts from other parts of the patients body if necessary, the skin is stitched back together.. Limbs can be reattached as many as four days after amputation if refrigerated, but ideally surgery occurs within a day [source: Engber].

The purpose of this in vitro study was to examine the effect of various powder-liquid ratios of an experimental resin-modified glass-ionomer polymer cement on dye penetration when the cement was used as a pit and fissure sealant. Eighty extracted human third molars were randomly assigned to one of four pit and fissure sealant conditions; a resin-based sealant or one of three variations in powder-liquid rations (1.4:1.0, 1.8:1.0, and 2.0:1.0) of an experimental, light-activated, resin-modified glass-ionomer cement. After sealant placement the teeth were thermocycled and immersed in methylene blue dye. The teeth were sectioned, and the extent of the dye penetration along the sealant-enamel interface was measured linearly. The resin-sealed occlusal fissures showed statistically significantly less dye penetration than did the three powder-liquid ratios of the experimental resin-modified glass-ionomer-cement sealant ...
Wouldnt it be nice if dental fillings not only repaired decay but were completely unnoticeable? Well, they can be, says your Zanesville, OH, family dentist, Dr. Jeff Labishak. Modern dentistry offers so many wonderful treatments that improve your oral health and make your smile look great. Tooth-colored fillings are one of these outstanding restorative services offered at The Smile Shack Family Dentistry.. What is a dental filling?. Traditionally, dentists have repaired, or filled, tooth decay with silver-colored amalgam. While these types of restorations last for years and prove to be strongest for large fillings in the back most teeth, amalgam simply looks unattractive. Also, it requires extensive enamel reduction to stay in place.. The tooth-colored filling and its benefits. Enter the tooth-colored filling.

What does dental bonding involve?. To begin, the dentist will isolate the teeth included in the procedure, etching them in preparation for bonding. After applying the etching conditioning liquid, the surface of the teeth will have small crevices that allow the tooth stronger adhesion with the bonding agent. The dentist will then apply a bonding resin which cements the composite in place. After several layers of tooth-colored composite are applied, the composite and bonding resin are shaped and hardened with a specially calibrated light. Once the composite is fully set, the bonded areas are smoothed, buffed, and polished to blend in naturally with the surrounding teeth. If you want to regain confidence in your smile, contact our practice to learn more about bonding.. ...

TY - JOUR. T1 - Water-dependent interfacial transition zone in resin-modified glass-ionomer cement/dentin interfaces. AU - Tay, F. R.. AU - Sidhu, S. K.. AU - Watson, T. F.. AU - Pashley, D. H.. PY - 2004/8. Y1 - 2004/8. N2 - The function of the interfacial transition zone (absorption layer) in resin-modified glass-ionomer cements bonded to deep dentin remains obscure. This study tested the hypotheses that the absorption layer is formed only in the presence of water derived from hydrated dentin and allows for better bonding of resin-modified glass-ionomer cements to dentin. Ten percent polyacrylic acid-conditioned, hydrated, and dehydrated deep dentin specimens were bonded with 2 resin-modified glass-ionomer cements and sealed with resins to prevent environmental water gain or loss. A non-particulate absorption layer was identified over hydrated dentin only, and was clearly discernible from the hybrid layer when bonded interfaces were examined with transmission electron microscopy. This layer ...
Composite resin is a suitable restorative material to restore an existing failed restoration, however it is unsuitable to restore a carious lesion due to the large amount of remineralizable dentin required to achieve a reliable adhesive base.. Glass ionomer cements (GIC) will adhere to caries affected dentin, minimizing the amount of tooth removal required to restore the tooth. Glass ionomer cement can be used as a restorative material in its own right or as a base for a composite resin overlay (sandwich restoration) where the remaining tooth structure is unsupported and requires a bonded composite to maintain its structural integrity.. For the following reasons glass ionomer cements are the material of choice for treating an active carious lesion:. • The weak bond strength of glass ionomer cement to sound and caries affected tooth structure does not affect the integrity of the restoration as there is not the polymerization shrinkage stress associated with composite resins.. • Glass ionomer ...
By the time a typical American reaches adulthood, at least one cavity has developed in a tooth, and every year, dentists fill millions of cavities. Unfortunately for most people, dental restorations dont last a lifetime. And every time a filling is replaced, the dentist must remove the old filling. Repeating this process whittles down the tooth until the remaining tooth structure is insufficient to hold a filling in place.. The lifespan of a dental restoration depends on many factors, including the ability of the restoration material to hold up in the harsh environment of the mouth. For tooth-colored composite fillings, the dental restoration may wear out in about seven to ten years.. "The composite-tooth interface is characteristically identified as the weak link in the composite restoration," explained Paulette Spencer, Ackers Distinguished Professor in the Department of Mechanical Engineering and Director of the Bioengineering Research Center at the University of Kansas School of ...
Restorations will be placed on four primary molar teeth with occlusal caries, in a split mouth design. 100 patients will be included in the study. The teeth will be randomized into four groups according to the restorative materials..

MATERIALS AND METHODS: Sixty standardized Class II box cavities were prepared under simulation of intrapulpal pressure with gingival margins located 1 mm below the cementoenamel junction (CEJ) in dentin. The samples were evenly distributed into six groups (A to F). After adhesive (XPBond) application, box preparations were filled with a first increment of either a nanohybrid composite (A, D) Ceram.X mono, or with one of two flowable materials SDR (B, E) or x-Flow (C, F). The first increments were 1 (A,B,C) or 4 mm (D,E,F) thick. All cavities were finally filled incrementally with Ceram.X mono. Replicas were prepared before and after TML (1.2 x 106 cycles; 5/50°C; maximum load 49 N). Replicas were evaluated for marginal adaptation (tooth/composite) using scanning electron microscopy (200X). The percentage of continuous margins was compared between and within groups before and after TML using ANOVA and Scheffés post-hoc tests ...

The other day I went to the dentist for a filling and a crown, a gold one. Or rather, I got fitted for it. They dental-dammed me up after a few rounds of Novocain shots, I looked like a right idiot. Or at least I imagined that I did. The dam was suffocating me, I could barely swallow. The drilling was louder than I ever remember. Is going to the dentist always this bad? Yes, apparently it is when you wait three and a half years between visits. I had dental insurance the entire time but refused to go. So basically, the work they were doing today was by my own choice. Some sort of self imposed torture. My ears were filled with tunes from my Ipod, my cavity with tooth-colored composite resin.
