Dental filling materials for managing carious lesions in the primary dentition

Abstract

Introduction: Atraumatic restorative treatment (ART) has been in use for the last couple of years. The survival rate of multi-surface restorations using this method has generally been very low for any given follow-up period. Most commonly quoted as the causes for the low survival rate included early restoration loss, poor choice of the cavity to be restored, operator factors, material factors and patient related factors, among other factors. Speculation has been that the premature loss may not actually denote failure to preserve the carious dental element, and that probably, the fluoride leach from the glass ionomer cement used with the technique, might be helping elongate the survival of the restored tooth. The question is whether, therefore, it is important to only look at the survival of the ART restoration or to also consider the survival of the tooth with premature restoration loss. Objective: To determine the current general survival rates of multi-surface ART restorations in the primary dentition, while simultaneously considering any consequences of the premature loss of these restorations in the primary dentition. The data for the study was obtained through Pubmed/Medline search for publications on multi-surface ART restorations from 2000 to 2011. Only publications on ART in the primary dentition were included and analyzed for survival rate, premature loss of restoration and effect of such loss. Conclusion: While the survival rates of multi-surface ART restorations in the review studies were low, the restorations appeared to provide some beneficial effects to the retention-longevity of the restored tooth even after the premature loss of restorations.

Bacterial Adhesion of Streptococcus mutans to Dental Material Surfaces

“…Because gold alloys are widely used in dentistry [ 34 ], not only for their preferred golden color but also because they maintain an extremely high chemical stability in the mouth, an Au-Pt alloy was selected for testing. This type of Au-Pt alloy also possesses several desirable mechanical properties such as high strength, ductility, and elasticity; moreover, its shows good biocompatibility due to the corrosion resistance of high noble elements [ 9 ].…”

Survival of extensive restorations in primary molars: 15‐year practice‐based study

“…When carious and developmental defects require operative therapy, there are several different materials and techniques available: resin composites (RC), glass‐ionomer cements (GIC), polyacid‐modified RC (PAMRC)/compomer, resin‐modified GIC (RMGIC), amalgam, different types of preformed crowns and techniques as well as indirect restorations. Preformed metal crowns (PMCs) in primary teeth are recommended in current guidelines of professional associations and societies such as American Association of Paediatric Dentistry and British Society of Paediatric Dentistry (BSPD).…”

“…RCs/PAMRC are more esthetic and allow conservative tooth preparation, although technique sensitive, indications in primary molars being also class II cavities, which do not extend beyond the proximal line angles. Amalgam restorations are generally less technique sensitive, esthetic and require macro‐retention in cavity preparation, thus, more loss of healthy tooth tissue, indications in primary molars being extensive lesions.…”

Mercury Contamination from Dental Amalgam

“…Additionally, dental materials such as zinc oxide-eugenol cements, polyacidmodified resin composite, also known as compomer, and resin modified glassionomer cement are commonly used worldwide. 18,59 Conclusions Mercury use in products and processes, including dental amalgams, is a cradle-to-grave deadly poison and a global pollutant. Even after the last mercury dental amalgam is placed, its toxic legacy will continue Review for decades, because of its pervasive bioaccumulation in the environment.…”
