Aim: Resin-containing restorative materials are widely used in the restoration of teeth. Our aim in this study is to examine the color change of beverages consumed cold on resin-containing restorative materials. Methodology: Samples were prepared using composite resins and resin-based CAD/CAM blocks. All prepared samples were kept in cold tea, cold coffee, coke, energy drink, and distilled water after polishing. The color values of the samples were measured with a spectrophotometer at the beginning, on the 1st, 7th and 30th days, and the color change values were calculated with the CIEDE2000 formula. Statistical analysis of color change values was performed using two-way analysis of variance (ANOVA) and Tukey multiple comparison tests (p0.05), at the end of the 7th and 30th days, cold tea caused the statistically highest color change (p0.05). Composite resins showed more color change than resin-based CAD/CAM blocks (p<0.05). Conclusion: Cold tea causes the most discoloration on resin-based materials. While the resin-containing CAD/CAM blocks showed a color change under the AT value in all cold drinks, the composite resins showed a color change above the AT value in cold tea and coffee.

All patients may not be able to correctly carry out mechanical teeth brushing methods in varied circumstances since they need for dexterity and specific motivation. On the other hand, since over-the-counter mouthwashes have various side effects, more natural counterparts are being researched. Oil pulling is an application that has been applied in India for 3000-5000 years and is good for various systemic diseases. This method, which is applied with different oils, provides various benefits to the teeth and surrounding tissues. The aim of this review is to provide an overview of the research on the oils used in oil pulling and their benefits.

Objective: The aim of our study is to evaluate in vitro the cytotoxic effect of the use of 2 mm and 4 mm bulk fill composites on gingival keratinocyte cells and the effect on antioxidant enzymes.Methods: In this study, various bulkfill composite resins(BCR) (Admira Fusion X-tra (VOCO GmbH, Cuxhaven, Germany), Reveal (Bisco, Japan), Estelite Bulk Fill Flow (Tokuyama, Japan) and Beautifil Bulk Flowable (Kyoto, Japan)) were prepared as 2 mm and 4 mm. The cell viability of the filtered composite resin extracts was examined with the MTT test, while the monomer rates released at the end of the 1st and 3rd days were measured with the HLPC device. ELISA method was used to evaluate the antioxidant enzymes Malondialdehyde, glutathione, catalase, superoxide dismutase, glutathione peroxidase 1 in the extracts that were incubated for 72 hours. Cell viability results obtained from the MTT test were evaluated using the Kruskal-Wallis and Mann-Whitney multiple comparison tests.(p

Hydrogels have a polymeric structure that can hold water in their three-dimensional networks thanks to their hydrophilic structure. Hydrogels have become a popular material used in the health field because they can hold water or biological fluids and have a structure similar to living tissues and are a biocompatible material with the ability to swell and shrink with various effects. In addition, providing the desired functionality, being recyclable and sterilizable are the positive aspects of this material. Due to these positive features, hydrogels are considered a material worth working on because they are suitable for dentistry practice. Therefore, various studies have been conducted with hydrogels due to the need for biocompatible materials in dentistry. These studies have also shown that they have found an area of use in dentistry as in the medical world and have provided useful developments. This review aims to examine the studies conducted with hydrogels in terms of dentistry.

Metformin is the most commonly prescribed drug in the treatment of diabetes. It has become popular in the field of dentistry with the discovery of the odontogenic, osteogenic and angiogenic effects of metformin in recent studies. The purpose of this review is to provide an overview of the studies conducted with metformin in the field of dentistry.
