Fluoride release by glass ionomer cements, compomer and giomer.

Dental research journal, 2009
To measure the amounts of fluoride released from fluoride-containing materials, four glass ionomer cements (Fuji IX, Fuji VII, Fuji IX Extra and Fuji II LC), a compomer (Dyract Extra) and a giomer (Beautifil) were used in this study.Twenty cylindrical specimens were prepared from each material.

In vitro assessment of cytotoxicity of giomer on human gingival fibroblasts [PDF]

African Journal of Biotechnology, 2009
Root coverage on restored root surfaces has been considered as a challenging issue. The evaluation of cytotoxic effects of restorative materials is a fundamental requirement for sustaining the cellattachment and the clinical success of root coverage. The aim of the present study was to compare the human gingival fibroblast cytotoxicity of the recently ...

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).

Cervical Microleakage in Giomer Restorations: An In Vitro Study

The Journal of Contemporary Dental Practice, 2020
The purpose of this in vitro study was to determine the effect of different composite placement techniques on gingival microleakage of giomer restorations.Sixty class II preparations were created in 30 extracted molar teeth with cervical margins 1 mm below the cementoenamel junction. The teeth were divided into three groups of 10 teeth each. In group I,

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

Optical properties and masking capacity of flowable giomers

Medicine and Pharmacy Reports, 2020
Background and aims. To assess the color, translucency and masking properties of novel flowable giomers. Methods. Three flowable giomers were used for the fabrication of 1-mm thick samples (n=126) in three consistencies (Beautifil flow Plus X F00; Beautifil flow F02; Beautifil flow Plus X F03, Shofu Dental Corporation, Japan) and two shades (A2 and A3)
