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...

BACKGROUND Amalgam that is used for dental fillings contains approximately 50% elemental mercury. During dental student training, amalgam is often removed by drilling without the use of water spray and suction, which are protective measures in preventing mercury aerosol. In this study we measured mercury vapor levels in ambient air during amalgam removal as is typically performed in dental trai...

AIM The purpose of the present study was to determine the influence of glass ionomer cement and amalgam restoration on the level of Streptococcus mutans in the interproximal plaque at periodic intervals and also to compare these values. MATERIALS AND METHODS Seventeen adult patients having two proximal carious lesions on any quadrant of the jaw (either opposing or contralateral) were selected...

The aim of this study was to verify the ability of different adhesive materials to prevent microleakage in bonded amalgam restorations. Standard cavities were prepared in both buccal and lingual surfaces of 35 bovine incisors. The gingival wall was located in cementum/dentin and the occlusal wall in enamel. Teeth (n=35) were divided into 5 groups, according to material employed (one glass-ionom...

Several European countries have guidelines suggesting that women should not receive mercury-containing dental amalgam fillings during pregnancy. One concern raised by several studies is that mercury exposure during pregnancy may lead to decreased birth weight. A population-based, case-control study was designed to investigate whether placement of mercury-containing fillings in 1993-2000 during ...

Nowadays, in endodontic field mineral trioxide aggregate (MTA; Dentsply, Tulsa Dental, Tulsa, OK, USA) has been introduced and widely used in many indications such as root-end filling, perforation repair, apexification, and pulp capping. Traditionally, various materials, such as amalgam, zinc oxide eugenol (ZOE), Intermediate Restorative Material (IRM; Dentsply Caulk, Milford, DE, USA), and sup...

Introduction: Mineral trioxide aggregate (MTA) has a variety of possible uses, including root-end filling material due to its excellent sealing ability in the presence of moisture and a high degree of biocompatibility. Aim: This case report demonstrates the use of MTA as an obturating material to promote periapical healing of root canals with large apical rarefactions. Materials and Methods: An...

Dental amalgam has been maligned as a filling material, both because of its clinical properties and its alleged effects on systemic health, but reports of its demise have been premature. As of 2008, 57 percent of dentists were placing amalgam (March 2008 Dental Products Report Survey). A large 2011 survey showed that dentists in the United States place more dental amalgam than composite for fir...

Aim The study evaluated the antibacterial effects of dental restorations such as nano-hybrid composite (Empress), a glass ionomer cement (GIC Gold label Type 9) and silver amalgam against Streptococcus mutans. Materials and Methods A modified bacterial suspension within the material assay was used to study the antibacterial effects. A volume of 20 μl of bacterial suspensions were placed in a ...

Adhesive techniques are now used for many dental restorative materials, including amalgam. Several generations of dentine bonding agents have been developed, mainly for bonding composite resins. When bonding is used with amalgam restorations, the need for retention and resistance form is reduced, the seal is improved, and some procedures, such as amalgam sealants, which were not previously poss...
