Objective. The purpose of this review paper is to review the literature regarding the toxicology of mercury from dental amalgam and evaluate current statements on dental amalgam. Materials and Methods. Two key-words "dental amalgam" and "toxicity" were used to search publications on dental amalgam biocompatibility published in peer-reviewed journals written in English. Manual search was also co...

Dental composites have almost entirely replaced amalgam restorations in the recent times. Amalgam were highly un-aesthetic and toxic to human body. prove be an aesthetic biocompatible alternative dental amalgam. But however, composite resins present with certain limitations such as inadequate mechanical properties wear resistance contact areas, primarily posterior teeth, contrast Therefore, not...

PURPOSE There is no data in the dental literature concerning the quality of the restorations performed in young children with early childhood caries (ECC) under sedation as compared with those treated under general anesthesia (GA). The aim of this study was to compare the quality of restorations and recurrent caries in 65 children with ECC who had dental treatment under GA or sedation. METHOD...

There has been dramatic progression in the adhesion of dental adhesives and resins to enamel and dentin in the 40 years since Buonocore1 introduced the technique of etching enamel with phosphoric acid to improve adhesion to enamel. The first dental adhesives bonded resins to enamel only, with little or no dentin adhesion. Subsequent generations have dramatically improved bond strength to dentin...

This article deals mainly with the development of dental casting techniques and formulation of the different groups of alloys used in the fabrication of ceramo-metal restorations. It is recognized that in order for the quality of dental cast restorations to be improved, having alloys with the proper composition is not enough. Biocompatibility, good mechanical and physical properties, longevity ...

The efficacy of restorative dentistry is dependent on a number of factors, including material quality, operator proficiency and the oral hygiene of the patient. The sum effect of all factors can be measured by recording the longevity of the restorations. Many studies focus on the age of restorations at the time of failure, others include the longevity of restorations which remain in situ. The s...

AIM At present, two different clinical procedures to ensure the adherence of indirect tooth restorations to the dental tissues are available: a traditional method based on a delayed dentin sealing (DDS) and an innovative approach that contemplates an immediate dentin sealing (IDS). In this study the authors highlight the advantages of the latter method (IDS), decribing the operating phases of t...

This retrospective study evaluated the clinical performance and the reasons for failure of anterior and posterior composite restorations placed by undergraduate dental students over a 3-year period. All cavities were restored using Prime & Bond 2.1 and TPH (Dentsply), according to the manufacturer's indications. One hundred and two patients who had received composite restorations by third and f...

The principal reason of gingival inflammation is bacterial plaque, along with other predisposing factors. These predisposing factors are calculus, malocclusion, faulty restorations, complications associated with orthodontic therapy, self- inflicted injuries, use of tobacco & radiation therapy. The contributing factors to gingival inflammation & periodontal destruction are deficient dental resto...
