Paediatric dentistry: Glass ionomer or giomer? [PDF]

International Journal of Applied Dental Sciences, 2021
Introduction: Giomers are composed of PRG fillers which in turn contain some ions, in addition to fluoride, which are beneficial to enamel so, it could be used for remineralization. Glass ionomer also contains fluoride and has been a commonly used material for many years.

Comparison of modern light‐curing hybrid resin‐based composites to the tooth structure: Static and dynamic mechanical parameters

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 110, Issue 9, Page 2121-2132, September 2022., 2022
Abstract The study aims to compare the way modern resin‐based composites (RBCs) respond to mechanical stress related to the tooth structure they are designed to replace. Eight representative light‐cured RBCs, including ormocers, giomers, RBCs with nano and agglomerated nanoparticles, prepolymerized, or compact fillers, were selected. Flexural strength,

Comparative Evaluation of Microleakage of Bioactive, Ormocer, and Conventional GIC Restorative Materials in Primary Molars: An In Vitro Study Microleakage of Three Restorative Materials

International Journal of Dentistry, Volume 2022, Issue 1, 2022., 2022
This in vitro study aimed to evaluate and compare the microleakage of bioactive, ormocer, and conventional glass ionomer cement (GIC) restorative materials in primary molars. In this study, class V cavities were prepared on the buccal surface of 75 noncarious extracted primary molars. The teeth were then restored as per the groups assigned.

Microleakage of pit and fissure sealings placed after enamel conditioning with phosphoric acid or with self‐etching primers/adhesives

Clinical and Experimental Dental Research, Volume 7, Issue 5, Page 763-771, October 2021., 2021
Abstract Background It is still not fully understood what pretreatment is best for achieving maximum tightness for pit and fissure sealings (PFS). Aim This study investigated microleakage of PFS placed after etching with phosphoric acid or after the application of self‐etching primers/adhesives (SEPA).

Assessing Fracture Resistance of Restored Premolars with Novel Composite Materials: An In Vitro Study

International Journal of Dentistry, Volume 2021, Issue 1, 2021., 2021
During restorative treatment, premolars restored with resin filling materials using the conventional incremental‐fill technique take longer restoration time and undermine the integrity of the tooth. The aim of this study was to assess fracture resistance of premolars restored by various types of novel bulk‐fill composite resin materials. Forty‐eight (n
