AIM The objective of this study was to assess the effect of heat application on the mechanical properties of glass ionomer cements. MATERIALS AND METHODS STUDY DESIGN experimental design. The effect of heat on glass ionomer cements during their setting was evaluated by measuring compressive strength, flexural strength and microhardness. Moroever, temperature changes from one surface of the...

Under clinical conditions, conventional glass-ionomer dental cements can be cured by application of heat from dental cure lamps, which causes acceleration in the setting. In order for this to be successful, such heat must be able to spread sufficiently through the cement to enhance cure, but not transmit heat so effectively that the underlying dental pulp of the tooth is damaged. The current st...

First generation glass ionomer bone cement was introduced by Wilson and Kent in 1970s and used in dental procedures . In 1989 Hehl et al. reported their experiences of fixing incudostapedial joint with glass ionomer cement . After this study many authors have presented their glass ionomer bone cement ossiculoplasty series [3,5] They showed that very satisfactory hearing improvements can be obta...

This study investigated the proliferation and differentiation potential of pluripotent mesenchymal cells on three resin-based restoratives using a typical pluripotent mesenchymal precursor cell line, C2C12. C2C12 cells were cultured for 3-21 days on cured specimens of a Bis-GMA/TEGDMA-based composite resin (APX; Clearfil AP-X), a 4-META/MMA-based resin cement (SB; Superbond C&B) or a HEMA-conta...

The purpose of this study is to compare the marginal leakage of two aesthetic cervical restorative materials viz the newly introduced light cured nano glass ionomer cement and nano ceramic composites, and also to evaluate the effect of unfilled resin sealant coating on marginal leakage of these aesthetic restorations. Thirty freshly extracted human upper premolars were used for the study. Class...

BACKGROUND Glass ionomer cements are widely used in pediatric practice due to their advantage of fluoride release and chemical bond to tooth structure. Adherence of the restorative material to the cavity walls is one of the most important characteristic for it to be proven as an ideal material as it prevents microleakage. AIMS AND OBJECTIVES This study was aimed at evaluating the microleakage...

BACKGROUND Chlorhexidine gluconate is a widely used antimicrobial agent. Adding chlorhexidine and quaternary ammonium compounds to filling materials, such as composite resins, acrylic resins, and glass ionomer cements increases the antibacterial property of restorative materials. This study includes antibacterial property of glass ionomer restorative cements with chlorhexidine gluconate. AIM ...

OBJECTIVE To do a comparative study of microleakage of glass ionomer cement (GIC) and chitosan modified glass ionomer cement and evaluate which exhibited lesser microleakage. MATERIALS AND METHODS Sixty freshly extracted sound primary molar teeth were obtained. Two groups of samples were created for the study which comprised of group I (glass ionomer cement-GIC) and group II (Chitosan modifie...

OBJECTIVE Glass carbomer cement represents a new generation of dental material, which mineralizes gradually into fluorapatite. The aim of this study was to evaluate the microleakage and marginal integrity of newly developed glass carbomer cement with and without protective surface coating (SC) in primary molars. METHODS Standardized cavities were prepared on extracted human primary molars, an...
