A Clinical Comparison of Decalcification Following Orthodontic Treatment Using Composite Resin and Reinforced Modified Glass Ionomer Cements


Book Description

Background and significance. Even with the advent of direct bonding, decalcification remains a problem in orthodontics today. Glass ionomer cements have been used in dentistry for fluoride release for years and may have beneficial use in orthodontics to reduce decalcification. Purpose. This study aims to evaluate the incidence in decalcification between orthodontic patients bonded with either composite resin or resin modified glass ionomer (RMGI) cements. Varying levels of hygiene and treatment time were also evaluated. Methods. Intraoral pre-treatment and post-treatment photographs from patients bonded with either RMGI or composite resin were evaluated for changes in decalcification. Patients were treated by the same practitioner and the data was gathered retrospectively. Results. Patients bonded with glass ionomer cement demonstrated significantly less decalcification than those bonded with composite resin. Treatment time and hygiene were not significant. Conclusions. Glass ionomer cements used for direct bonding reduce decalcification in orthodontic patients on a fluoride protocol.

Glass-Ionomers in Dentistry


Book Description

This concise handbook covers all aspects of glass-ionomer cements, from the development of these materials in the early 1970s through to the current state of the art. Their physical, chemical, biological, and clinical properties are described as well as how their formulation and usage have evolved over time, giving rise to newer subcategories of the parent materials. Detailed coverage is provided on the clinical use of glass-ionomer cements in restorative and pediatric dentistry and in widely taught and practiced newer approaches, including atraumatic restorative treatment and minimal intervention dentistry. The authors are internationally acclaimed experts who present information in an easy-to-follow format that will appeal to readers. With the renewed worldwide quest for substitute materials for the more traditional amalgam, glass-ionomer cements have the potential for further development and may play a significant role in future trends.​




Glass Ionomer Cement


Book Description

The glass ionomer cements are more aesthetically pleasing than metallic restoratives, although less so than resin composites, and they are considered one of the safest restorative materials. When reviewing the dental luting cements, glass ionomers possess several advantages compared to the resin composite, zinc phosphate and other dental cements. The glass ionomer cements can be used in a wide range of clinical applications. They also have anticariogenic potential produced by incorporated fluorine, good biocompatibility, better chemical adhesion to the tooth structure, well balanced physical properties, and good manipulability. The clinical applications of glass ionomer cements are as luting agents, fillings for anterior and posterior teeth, linings, bases and cores, fissure protection materials for prevention of caries, sealants for patients with allergic reactions to resin based materials, bonding agents for composite resin, root canal fillings, and adhesive cements for orthodontic brackets. The reason glass ionomer cement is widely applicable is that it can exhibit varied physical properties by changing the powder liquid ratio or the powder and liquid formulation.

An Atlas of Glass-Ionomer Cements


Book Description

The status of glass-ionomers as a restorative material continues to improve along with their reputation for longevity. They have now been shown to be moderately bioactive, so they have a very important role to play in remineralizing tooth structure and helping to heal carious lesions. This comprehensive clinical guide to their uses in operative dentistry has been updated throughout.
