A qualitative study of barriers and facilitators to the implementation of a pilot school-based, toothbrushing programme.

Background: While supervised toothbrushing programmes have been established in many countries of the world, little is known about different perspectives on their implementation. The aim of the study was to explore stakeholders' barriers and facilitators to implementation of a school-based toothbrushing programme in Taiwan.

Methods: Focus groups and interviews were used to explore the views of elementary school students, teachers, staff, and nurses in a piloted school-based toothbrushing programme.

A scoping review of intervention components of school-based oral health-related behavioural interventions using the Theoretical Domains Framework.

The aim of this study was to review the intervention components of school-based oral health-related behavioural interventions using the Theoretical Domains Framework (TDF). We identified relevant papers from the review of Cooper et al., and these papers came from both the original inclusion and exclusion article lists.

Outcome comparison between diode laser pulpotomy and formocresol pulpotomy on human primary molars.

Background/purpose: Diode laser is widely used in dentistry, especially on treating soft tissues. Currently neither the effect of diode laser pulpotomy nor its comparison with formocresol (FC) pulpotomy has been fully investigated. Therefore the purpose of this study was to investigate the clinical and radiographic outcomes of diode laser pulpotomy and formocresol pulpotomy on human primary molars.

Portland cement induces human periodontal ligament cells to differentiate by upregulating miR-146a.

Background/purpose: Bioaggregates such as Portland cement (PC) can be an economical alternative for mineral trioxide aggregate (MTA) with additional benefit of less discoloration. MTA has been known to induce differentiations of several dental cells. MicroRNAs are important regulators of biological processes, including differentiation, physiologic homeostasis, and disease progression.

A 10-year trend of dental treatments under general anesthesia of children in Taipei Veterans General Hospital.

Background: General anesthesia (GA) as a pediatric dental procedure is a well-established method of behavior management. However, studies of pediatric dentistry under GA have mostly focused on handicapped patients, and various retrospective studies in Taiwan have mainly reviewed only a limited number of years. The purpose of the present study was to report trends in pediatric dental treatment performed under GA over the past 10 years.

The impact of kiddy dentures on maxillary arch growth.

Background: Kiddy dentures are used to restore the self-confidence, chewing function, and pronunciation of children or when a care provider is concerned about the loss of incisor teeth. However, most studies to date have investigated normal dental arch development, and only a few have explored the effect of kiddy dentures on upper arch development.

Methods: Fourteen Taiwanese children (7 male and 7 female) who were wearing kiddy dentures due to the loss of their upper anterior teeth were enrolled in this study.

Clinical evaluation of the timing of mesiodens removal.

Background: Mesiodens is a common clinical finding among children and has a higher prevalence in Asian populations. The timing of the removal of mesiodens remains controversial. Clinical studies comparing early versus late removal are lacking.

Microleakage in different primary tooth restorations.

Background: Microleakage may cause tooth sensitivity, secondary caries, discoloration and even failure of the restoration. In order to overcome these potential problems, materials that are able to bind to the tooth structure have been developed, such as composite resin and glass ionomer cement. The purpose of the study was to compare microleakage arising from amalgam (Am), composite resin (CR), glass ionomer (GI), Ketac-Silver (KS), and GI filling with banding (GI+B) when these materials are used for class II restoration of a primary molar.

MicroRNA-31 upregulation predicts increased risk of progression of oral potentially malignant disorder.

Objectives: MicroRNAs (miRNAs, miRs) have shown diagnostic and prognostic potential for oral cancer but their role in oral potentially malignant disorder (OPMD) has been less investigated. We aimed to assess whether miR-21 and miR-31, two of the most relevant miRNAs in oral cancer, are useful as prognostic factors for OPMD progression.

Materials And Methods: miR-21 and miR-31 in 20 saliva samples and 46 tissue samples from patients with OPMD (mean follow-up of 820days) were analyzed by quantitative reverse transcription PCR and in situ hybridization, respectively.

Lipopolysaccharide induces the migration of human dental pulp cells by up-regulating miR-146a.

Introduction: MicroRNAs are small noncoding RNAs that play crucial roles in regulating normal and pathologic functions. Bacterial lipopolysaccharide (LPS) is one of the key regulators of pulpal pathogenesis. This study investigated how LPS regulates microRNA expression and affects the phenotype of human dental pulp cells (DPCs).
