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.

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.

Influence of maternal attitudes and parenting style on children`s dental caries experience.

Objective: To evaluate the effect parental attitudes have on the dental caries experience of children.

Methods: The cross-sectional observational study was conducted at Yeditepe University, Istanbul, Turkey, from March to September 2019, and comprised mothers of children who came to the Department of Paediatric Dentistry for treatment of children. Multi-variable poisson regression model was run to predict prevalence of dental caries.

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.

Effect of pediatric multivitamin syrups and effervescent tablets on the surface microhardness and roughness of restorative materials: An in vitro study.

Background/purpose: Multivitamin syrups and effervescent tablets are commonly used for dietary support in children; however, these preparations may have detrimental effects on the surface of restorative materials. The aim of this study was to evaluate the effect of two multivitamin syrups and two effervescent tablets taken daily on the surface microhardness and roughness of two different restorative materials.

Materials And Methods: The study groups were comprised of a conventional glass ionomer cement, Ketac Molar, and a giomer, Beautifil II.

Assessment of shear bond strength and microleakage of fissure sealant following enamel deproteinization: An study.

Background: To evaluate the effect of two different deproteinizing agents (5.25% sodium hypochlorite and Papacarie®) prior to acid etching on the shear bond strength and microleakage of a fissure sealant material.

Material And Methods: A total of 123 extracted noncarious human third molar teeth were randomly divided into three groups for each test: acid etching alone (control) (C), sodium hypochlorite (NaOCl), and Papacarie Duo® (PC).

Effect of two different polishing systems on fluoride release, surface roughness and bacterial adhesion of newly developed restorative materials.

Objectives: To evaluate the effects of two different polishing systems on fluoride release, surface roughness and bacterial adhesion of five restorative materials MATERIALS AND METHODS: The study groups were comprised of five different restorative materials, Beautifil II (B); GCP Glass Fill (G); Amalgomer CR (A); Dyract XP (D); Fuji IX GP (F) and 21 specimens were prepared from each material. Each group was divided into three subgroups according to the polishing system: Mylar (control) (C), Sof-lex (S), and Enhance-Pogo (EP). The amount of fluoride release was measured using a fluoride ion-selective electrode and surface roughness was investigated with a profilometer.

Antibacterial efficacy of diode and Er:YAG laser irradiation in experimentally contaminated primary molar root canals.

Objective: In vitro comparison of the antibacterial efficacy of Diode and Er:YAG laser irradiation with that of NaOCl irrigation in contaminated primary molar root canals.

Study Design: 96 root canals prepared from 32 extracted primary molar teeth were mechanically enlarged and the teeth were randomly divided into 4 subgroups. The roots were inoculated with an overnight culture of Enterococcus faecalis in tryptic soy broth for 24 hours.

Short-term effect of ice-cream containing Bifidobacterium lactis Bb-12 on the number of salivary mutans streptococci and lactobacilli.

Objective: Probiotic bacteria are thought to reduce the risk of some infectious diseases. The aim of the present study was to examine whether or not short-term consumption of ice-cream containing bifidobacteria can affect the salivary levels of mutans streptococci and lactobacilli in young adults.

Material And Methods: A double-blind, randomized crossover study was performed and 24 healthy subjects (mean age 20 years) were followed over 4 periods.

Management of an unerupted dilacerated maxillary central incisor: a case report.

A case with a dilacerated maxillary permanent central incisor, treated with forced eruption technique is illustrated and the results of the 4-year follow up are presented. After the successful eruption of the tooth, the root development was completed and the root canal was obliterated. The 4-year follow-up results revealed the tooth to be still functional and the radiographic evaluation showed that the periodontal and periapical tissues were intact and healthy.

Evaluation of the fluoride release from orthodontic band cements.

Purpose: To compare the fluoride levels released from a polyacid-modified resin composite (Ultra BandLok), a resin-modified glass-ionomer cement (Multicure) and a conventional glass-ionomer cement (Meron).

Methods: Fluoride concentration in the deionized water was measured at 1, 2, 3, 7, 14 and 28 days. Fluoride measurement was undertaken using a fluoride ion selective electrode connected to an ion-analyzer.
