Antibacterial effects of dentifrices against in children: a comparative study.

Fluoridated dentifrices have antibacterial effects on children's teeth. On the other hand, the side effects encountered with the use of them have led researchers to look for safe alternatives. This study aimed to determine the antibacterial effect of different commercially available fluoride-free dentifrices on () in comparison with different concentrations of fluoridated dentifrices.

Effects of maternal anxiety and sociodemographic factors on fluoride knowledge and opinions about fluoride-containing oral products. A cross-sectional study.

Aim: To assess the relationship between maternal anxiety and so- cioeconomic status, focusing on mothers' knowledge of fluoride and their views on fluoride-containing oral products.

Methods: In a cross-sectional study design involving 224 mother- child pairs, mothers' socioeconomic status, level of knowledge on fluoride, and perspectives on fluoride toothpaste and topical fluoride gel/varnish were assessed through self-administered questionnaires. Maternal anxiety levels were measured using the Spielberg State-Trait Anxiety Inventory.

Evaluation of the usefulness and quality of YouTube™ videos about children's electric toothbrushes.

Objectives: The effectiveness of mechanical tooth cleaning, which plays a crucial role in biofilm control, depends on the type of brush and technique. Parents can refer to websites such as YouTube™ for guidance on the selection and use of electric toothbrushes. The objective of this study was to examine the usefulness, quality and accuracy of the information on YouTube™ videos about electric toothbrushes for children.

The Effect of Two Different Light-Curing Units and Curing Times on Bulk-Fill Restorative Materials.

This study aimed to evaluate the effect of two different light-curing units and curing times on the surface microhardness (SMH), compressive strength (CS), and volumetric shrinkage (VS) of four restorative materials (Filtek Z250, Filtek Bulk Fill Posterior, Beautifil Bulk Restorative, ACTIVA BioACTIVE). For all tests, each material was divided into two groups depending on the curing unit (Woodpecker LED-E and CarboLED), and each curing unit group was further divided into two subgroups according to curing time (10 s and 20 s). SMH was evaluated using a Vickers hardness tester, CS was tested using a universal testing machine, and VS was measured using video imaging.

Antibacterial effects of saliva substitutes containing lysozyme or lactoferrin against Streptococcus mutans.

Objective: To determine the antibacterial effects of different saliva-substitutes-containing-lysozyme(LYZ) or-lactoferrin(LF) on Streptococcus mutans(S. mutans) in comparison with human saliva.

Design: In vitro wound-healing assay was performed with L929 mouse fibroblast cell line by using various concentrations of LYZ and LF to determine optimum concentrations and to confirm do not show any cytotoxicity of proteins according to cell culture studies.
