Assessing motivational interviewing integrity in the Toddler Oral Health Intervention study.

Objectives: The Toddler Oral Health Intervention (TOHI) was launched in 2017 to promote oral health prevention at well-baby clinics, with a focus on parents with children aged 6-48 months. This study aims to evaluate the integrity of motivational interviewing (MI) as one of the core intervention pillars in the TOHI study.

Methods: The TOHI study was conducted at nine well-baby clinics in the central and southern regions of the Netherlands, with 11 trained oral health coaches (OHCs) delivering a tailored individual counselling programme.

Validation of an improved questionnaire assessing the social cognitive constructs of the Health Action Process Approach among parents regarding brushing their children's teeth.

Objective: The Health Action Process Approach (HAPA) describes social cognitive constructs related to behaviour change. A validated questionnaire is needed to measure these constructs in paediatric dentistry. The aim of this study was to improve an existing HAPA-based questionnaire for parents regarding brushing their children's teeth and to assess its validity and reliability in a population of parents of high caries risk children.

Mechanical plaque removal in step-1 of care.

Maintaining a regular oral hygiene routine is essential for taking care of our mouths, ensuring healthy teeth, and achieving fresh breath. Patient education on oral hygiene is an important component of their overall treatment. Firstly, patients should be informed about the direct connection between bacteria in dental plaque and oral diseases.

Construction of a questionnaire based on the Health Action Process Approach for psycho-social cognitive determinants of parents in brushing children's teeth in the Netherlands.

Background: The health action process approach (HAPA) model is promising to increase the frequency of brushing children's teeth by parents to improve their children's oral health. A validated HAPA questionnaire is needed as one of the measures of the effects of such an intervention.

Objectives: The aim of this study was to evaluate whether our data, based on a translated and adopted version of the Health Action Process Approach (HAPA)-based questionnaire on dental flossing, supported the constructs of the HAPA model.

Exploring the development, evaluation and implementation of complex health interventions to prevent early childhood caries in preschool children: A scoping review protocol.

Objective: This scoping review aims to identify complex health interventions (CHI's) to prevent early childhood caries (ECC), explore the level of complexity of the identified CHI's, and explore the details of their development, evaluation, and implementation.

Introduction: Many interventions to prevent ECC have multiple interacting components and can be seen as CHI's. Recent reviews on these interventions have found inconclusive effects, which may be due to differences in the development, evaluation, and implementation of CHI's.

Health action process approach in oral health behaviour: Target interventions, constructs and groups-A systematic review.

Objective: The aim of this study was to systematically map the Health Action Process Approach (HAPA)-based interventions in dentistry in relation to the type of intervention, the target groups and the constructs of the HAPA model that are used in the study and to assess the clinical relevance of the studies.

Methods: A search in the databases of the National Library of Medicine (MEDLINE-PubMed), PsychINFO and Cochrane-CENTRAL was conducted. A quality assessment to estimate the risk of bias and a qualitative descriptive analysis were performed.

Oral Health Coaches at Well-Baby Clinics to Promote Oral Health in Preschool Children From the First Erupted Tooth: Protocol for a Multisite, Pragmatic Randomized Controlled Trial.

Background: Early childhood caries is considered one of the most prevalent diseases in childhood, affecting almost half of preschool-age children globally. In the Netherlands, approximately one-third of children aged 5 years already have dental caries, and dental care providers experience problems reaching out to these children.

Objective: Within the proposed trial, we aim to test the hypothesis that, compared to children who receive usual care, children who receive the Toddler Oral Health Intervention as add-on care will have a reduced cumulative caries incidence and caries incidence density at the age of 48 months.

The Effect of Various Fluoride Products on Dentine Lesions during pH-Cycling.

This study compared the effect of topically applied fluoride products on dentine lesions in an in vitro experiment. Demineralized bovine dentine specimens were treated once with either SDF solution (35,400 ppm F), NaF varnish (22,600 ppm F), TiF4 solution (9,200 ppm F), SnF2 gel (1,000 ppm F), no treatment (control), or preserved as baseline lesions. After the application and subsequent removal of the fluoride products, the specimens were subjected to pH-cycling.

Parents' Willingness to Invest in Primary Oral Health Prevention for Their Preschool Children.

There is growing evidence for the beneficial effects of starting oral health prevention early in life. Preventing dental caries in very young children requires considerable investment from parents. Therefore, this cross-sectional study aimed to explore parents' willingness to pay (WTP) and willingness to invest in time (WTIT) for primary oral health prevention in preschool children and describe whether these are related to the parents' demographic, socio-economic and behavioural characteristics.

Saliva-derived microcosm biofilms grown on different oral surfaces in vitro.

The microbial composition of a specific oral niche could be influenced by initial bacterial adherence, nutrient and physiological property of the local surface. To investigate the influence of nutrient and surface properties on microbial composition, saliva-derived biofilms were grown in agar on three substrata: Reconstructed Human Gingiva (RHG), a hydroxyapatite (HAP) surface, and a titanium (TI) surface. Agar was mixed with either Brain Heart Infusion (BHI) or Thompson (TP) medium.

The effect of equal fluoride concentrations in silver diamine fluoride and potassium fluoride on demineralized dentin during pH-cycling: chemical data.

The actual contribution of silver in silver diamine fluoride (SDF) towards the anti-demineralizing effect is unclear. This study compared the effects of single applications of three concentrations of fluoride (4.1%, 1.

Chapter 7: Sugar and Dental Caries.

Sugar is added to food for a multitude of functions: fermentation, preservation, physical and chemical, and also to satisfy the consumer's preference for sweetness. Unfortunately, sugar consumption is also a main aetiological factor for dental caries. The relationship between sugar and caries was established in the latter half of the 19th century.

The effect of using a mobile application ("WhiteTeeth") on improving oral hygiene: A randomized controlled trial.

Objective: To evaluate the effectiveness of the WhiteTeeth mobile app, a theory-based mobile health (mHealth) program for promoting oral hygiene in adolescent orthodontic patients.

Methods: In this parallel randomized controlled trial, the data of 132 adolescents were collected during three orthodontic check-ups: at baseline (T0), at 6-week follow-up (T1) and at 12-week follow-up (T2). The intervention group was given access to the WhiteTeeth app in addition to usual care (n = 67).

Biomineralization of dentin.

A single biomineralization of demineralized dentin is significant to restore the demineralized dentin due to dental caries or erosion. In recent years, meaningful progress has been made regarding the mechanisms involved in the biomineralization of dentin collagen. Concepts changing from the classical ion-based crystallization to non-classical particle-based crystallization, inspired a different strategy to infiltrate the demineralized dentin collagen.

Genetic Loci Associated With Fluoride Resistance in .

The prolonged exposure of the cariogenic bacterial species to high concentrations of fluoride leads to the development of fluoride resistance in this species. Previous studies confirmed the involvement of a mutation in a single chromosomal region in the occurrence of fluoride resistance. The involvement of multiple genomic mutations has not been verified.

Multi-species oral biofilm promotes reconstructed human gingiva epithelial barrier function.

Since the oral mucosa is continuously exposed to abundant microbes, one of its most important defense features is a highly proliferative, thick, stratified epithelium. The cellular mechanisms responsible for this are still unknown. The aim of this study was to determine whether multi-species oral biofilm contribute to the extensive stratification and primed antimicrobial defense in epithelium.

Effects of bacterial physiological states and bacterial species on host-microbe interactions.

This study investigated how the physiological states of Aggregatibacter actinomycetemcomitans (Aa) and Streptococcus mitis affect their intracellular invasion capabilities and the resulting host cell responses. The physiological states included two forms of planktonic states, floating or sedimented (by centrifugation) and the biofilm state (with centrifugation). Confluent epithelial Ca9-22 cells were challenged with floating or sedimented planktonic cultures, or with 24-h biofilms for 3 h.

A Mobile App (WhiteTeeth) to Promote Good Oral Health Behavior Among Dutch Adolescents with Fixed Orthodontic Appliances: Intervention Mapping Approach.

Background: The insertion of fixed orthodontic appliances increases the risk of dental caries, particularly in adolescents. Caries can be prevented through good oral health behavior. To support adolescents with fixed orthodontic appliances and for promoting oral health behavior, we developed a theory- and evidence-based mHealth program, the WhiteTeeth app.

Sugar Restriction for Caries Prevention: Amount and Frequency. Which Is More Important?

The World Health Organization guideline to use less sugar may be an opportunity and support for dentistry in its goal to get the message of using less sugar across to the public. Two ways (with all the combinations of these) to achieve a reduction of sugar consumption are the reduction of the amount of sugar in products or the reduction of the frequency of consumption of sugar-containing products. Which sugar-reducing strategy is best for caries prevention? To answer this question, this manuscript discusses the shape of the dose-response association between sugar intake and caries, the influence of fluoridated toothpaste on the association of sugar intake and caries and the relative contribution of frequency and amount of sugar intake to caries levels.

Dental caries and externalizing behaviour problems in a high-risk child population.

The aim of this study was to assess the association between externalizing behaviour problems and dental caries in children. A further objective was to explore direct and indirect pathways between sociodemographic factors, family functioning and parenting factors, oral health behaviours, externalizing behaviour problems, and dental caries using structural equation modelling. Cross-sectional data were collected on 251, 5- to 8-yr-old children from a paediatric dental practice in the Netherlands.

European Organization for Caries Research Workshop: Methodology for Determination of Potentially Available Fluoride in Toothpastes.

Toothpastes are the most universally accepted form of fluoride delivery for caries prevention. To provide anti-caries benefits, they must be able to release fluoride during the time of tooth brushing or post brushing into the oral cavity. However, there is no standard accepted procedure to measure how much fluoride in a toothpaste may be (bio) available for release.

Efficacy of probiotics: clinical and microbial parameters of halitosis.

Background & Aim: Halitosis is defined as an offensive breath odour of whatever source and therefore may affect a person's social interactions. Intra-oral halitosis is a result of bacterial activity. Therefore, probiotics may offer an appropriate and biological solution as a part of the therapy of intra-oral halitosis.
