Whitening efficacy and removal of extrinsic tooth stain of sodium phytate-containing whitening toothpaste: a randomized controlled trial.

Objective: The study aimed to evaluate the whitening efficacy and removal of extrinsic tooth stain of sodium phytate-containing whitening toothpaste, as well as to evaluate participant satisfaction.

Methods: A total of eighty participants were recruited for this randomized, triple-blind controlled trial and were randomly assigned to either the test group (toothpaste containing 0.875% sodium phytate, ST) or the control group (toothpaste without sodium phytate, CT).

An experiential service-learning project on oral health examination and education.

Background: It has been demonstrated that experiential service-learning is effective in fields including public health and medicine. Preventive Dentistry is a practical course, and Oral Health Examination and Education is a topic that is suitable for teaching with experiential service-learning. This study describes an example of experiential service-learning in Preventive Dentistry named "Oral Health Examination and Education Project" and also evaluates its effectiveness among dental students.

Parental Feeding Styles and Risk of a New Carious Lesion in Preschool Children: A Longitudinal Study.

Parents may influence children's intake of sweets and sugar-sweetened beverages through their feeding styles. This study prospectively assessed the association between parental feeding styles and caries risk in preschool children. In November and December 2021, we recruited 1181 preschool children aged 3-4 years in Guangzhou, China, and then conducted a follow-up visit after 15 months.

Comparison of modified bass, rolling, and current toothbrushing techniques for the efficacy of plaque control - A randomized trial.

Objects: This study aimed to compare the effectiveness of the modified Bass technique (MBT), the Rolling technique and the current brushing technique(CBT) for plaque removal and to assess the acceptability of the first two brushing techniques.

Methods: 180 participants were randomly assigned to PowerPoint-based training with a demonstration of either the MBT plus basic toothbrushing, the Rolling technique plus basic toothbrushing, or the basics of tooth brushing alone (CBT group). The participants were asked to brush their teeth based on what they had learned.

The Oral Microbiome Impacts the Link between Sugar Consumption and Caries: A Preliminary Study.

Background: The excessive and frequent intake of refined sugar leads to caries. However, the relationship between the amount of sugar intake and the risk of caries is not always consistent. Oral microbial profile and function may impact the link between them.

Oral Mycobiome Differences in Various Spatial Niches With and Without Severe Early Childhood Caries.

Severe early childhood caries (S-ECC) is a microbe-mediated disease with tooth hard tissue destruction. However, the role of the fungal community in various ecological niches of deciduous dental caries has not been fully elucidated. This study aimed to analyze the differences of mycobiome in diverse spatial niches with and without S-ECC.

Metagenomic Analysis of Dental Plaque on Pit and Fissure Sites With and Without Caries Among Adolescents.

Caries is one of the most prevalent infectious diseases worldwide and is driven by the dysbiosis of dental biofilms adhering to tooth surfaces. The pits and fissured surfaces are the most susceptible sites of caries. However, information on the taxonomic composition and functional characteristics of the plaque microbiota in the pit and fissure sites is very limited.

A New Model for Caries Risk Prediction in Teenagers Using a Machine Learning Algorithm Based on Environmental and Genetic Factors.

Dental caries is a multifactorial disease that can be caused by interactions between genetic and environmental risk factors. Despite the availability of caries risk assessment tools, caries risk prediction models incorporating new factors, such as human genetic markers, have not yet been reported. The aim of this study was to construct a new model for caries risk prediction in teenagers, based on environmental and genetic factors, using a machine learning algorithm.

A two-week single-group longitudinal test of a new sonic-powered toothbrush simulating the 'bass brushing technique' with tapered bristles on the brush head for reduction of dental plaque and gingivitis.

Objective: To investigate the effect of a new powered toothbrush with tapered bristles on the brush head for the reduction of dental plaque and gingivitis.

Methods: This was a single-centre, single-group, longitudinal clinical trial. Thirty-two participants who were typical manual toothbrush users were recruited and assigned the sonic-powered brush.

Enamel and Dentin Caries Risk Factors of Adolescents in the Context of the International Caries Detection and Assessment System (ICDAS): A Longitudinal Study.

The objective of this study was to identify risk factors for enamel and dentin caries in adolescents. This 1-year longitudinal study was conducted in 2018 and 2019; 13- to 14-year-old adolescents were recruited. The merged International Caries Detection and Assessment System (ICDAS) was used to identify caries.

Interactions with the aquaporin 5 gene increase the susceptibility to molar-incisor hypomineralization.

Objective: The aim of this study was to evaluate whether individual genetic factors involved in amelogenesis, the immune response and water channel proteins may increase the susceptibility to Molar-Incisor Hypomineralization (MIH) in Chinese children.

Design: DNA samples were collected from 86 cases with MIH cases and 344 controls. Sixteen single-nucleotide polymorphisms (SNPs) were investigated.

Effect of Different Glucose Concentrations on Small RNA Levels and Adherence of Streptococcus mutans.

Streptococcus mutans (S. mutans) adheres to the tooth surface, metabolizes carbohydrates, and produces acid products, leading to enamel demineralization-the onset of dental caries. Rapid acidification by S.

Variation in Enamel Formation Genes Influences Enamel Demineralization in a Biofilm Model.

Genetic studies have shown that variations in enamel formation genes are associated with caries susceptibility. The aim of this study was to test whether variants in these genes are associated with dental enamel demineralization in a biofilm model. DNA and enamel samples were obtained from 213 individuals.
