Filter by:Effect of CPP-ACP pastes with/without Fluoride on White spot lesion progression, salivary pH and fluoride release in high caries risk Patients, over 3 month period using VistaCam, Digital pH meter and Selective ion electrode.
The sample will be, at least, 90 primary molars, randomly distributed into three groups: Group 1: IPC; Group 2: SE; Group 3: SCR. Teeth must present deep caries lesions (at least 2/3 of dentin depth), pulp vitality (no clinical or radiographical signs of pulp disease, such as abcesses, fistulae, root resorption, abnormal tooth mobility). This study received approval by the Ethics Committee of Fluminense Federal University (UFF; Brazil) - # CAAE: 58812816.8.0000.5626. The study started in January, 2017; and will finish in December, 2020. Patients will be selected from the public schools in Nova Friburgo. The dental exams and treatment procedures will be done at the clinics from the School of Dentistry, Health Institute of Nova Friburgo (ISNF). Laboratory proceedings will be done at: - Clinical and Microbiological Research Laboratory (LAB PECMA - ISNF) - Sample storage, bacterial cultivation and identification. - University of North Carolina at Chapel Hill - Rio de Janeiro Federal University
This trial is a Phase III, multisite, randomized, placebo-controlled trial, with two parallel groups. The groups are SDF or placebo and they are applied every 6 months. The primary hypothesis of the trial is that SDF is better than placebo for stopping cavities with dentin exposed in baby teeth when assessed at 6 months after initial application.
Preformed metal crowns (PMCs) have high success rates in restoring primary molars in children but they were not generally used by dentists, especially in developing countries due to its demand of high clinical skills with the conventional technique (CT). The biological approach, Hall technique (HT), requires less training and can be placed by less experienced dental operators including therapists. Previous studies were mainly carried out in developed countries. The aims were to investigate and compare the efficacies and cost-effectiveness of PMCs placed by these two techniques.
This application, BeReady2Smile, will promote dental health behavioral parenting strategies among parents by incorporating a behavioral program for their children. Parents use a multimedia coordinated oral health prevention intervention program to promote dental health targeted at parents of young children attending parenting education classes and families receiving home visiting services through Head Start. Once developed, BeReady2Smile will be field tested for usability and usefulness with a group of parents of young children. Parents will rate the level of support needed, confidence in the system, and ease of use at each stage in the development, initiation, and maintenance of the system.
The hypothesis is that Addition of copper or zinc nanoparticles to a dental adhesive confers antimicrobial and enzymatic degradation-resistant properties, retaining its adhesion mechanical properties and biocompatibility. To corroborate this hypothesis two groups of a dental adhesive doped with copper or zinc nanoparticles should be develop with a respective structural characterization by SEM-EDX, AFM and FTIR. This should be followed by a test of the antimicrobial activity of adhesive and a study of the influence of adhesive nanocomposites on matrix metalloproteases levels and/or activity in vitro to determine some concentrations more relevant. These would proceed to next stage. With the selected adhesive doped concentrations should be evaluate mechanical properties of doped adhesives and assess the biocompatibility by assays in primary cultured gingival fibroblast and cells type odontoblasts. Finally, once the concentration of either Cu- or Zn-doped adhesives is known, these will be evaluated with a clinical design phase in an in vivo model to study antimicrobial properties, matrix metaloproteases levels and/or activity. We will also study biocompatibility of adhesive nanocomposites and mechanical properties to corroborate the in vitro and ex vivo properties determined. There are results using copper nanoparticle on biomaterials that corroborates some properties such as antimicrobial activity against various species and copper release. All the evidence suggests that at low concentrations of copper nanoparticles, there are no significant effects on mechanical properties but with added antibacterial properties on the adhesive
Maintaining dental pulp vitality is crucial for tooth preservation and functionality. Untreated dental caries may lead to pulp necrosis and infection, affecting children's growth and well-being. The first permanent teeth erupt around 6 years old. These are the first molars (FPM), which are frequently affected by caries, soon after their eruption. In the present application, our main goal is to determine whether two treatment groups (MTA and TheraCal) are long-term effective in preserving pulp vitality among children' FPM affected by deep caries.
Evaluate the effect of propolis extract mouthwash and pomegranate extract mouthwash on taste alteration, salivary pH and antibacterial activity against streptococcus mutans in high caries risk patients.
Scientific background(Statement of the problem): Dental caries is a disease that occurs through complex interaction of four major factors: the host, acidogenic bacteria, fermentable carbohydrates and time. There are many factors which contribute to dental caries incidence but do not seen in clinical examination. Those things are considered as dental caries risk factors, such as socioeconomic, attitudes, knowledge and behavior toward oral health. These risk factors play an important role in incidence of the disease, significantly associated with disease progression . The traditional "drill and fill "concept has served to restore function and esthetics but it has failed to prevent development of new carious lesions. In recent years; better understanding of nature of carious process has changed this operative treatment concept to non destructive risk -based caries management. Caries risk assessment is a procedure used to predict dental caries development before clinical onset of disease, through assessing risk factors contributing to progress of dental caries and let oral health care professionals to be more active in identifying and referring high risk patients for proper treatment and required prevention. Rationale for carrying out this study : Many studies have measured dentists' knowledge toward caries risk assessment all over the world, but no studies have examined Egyptian Dentists' subjective ratings of the importance of specific caries risk factors or tested whether they use this information in treatment planning. So the aim of this study to assess knowledge, attitude and practice toward caries risk assessment and management among group of dental interns in Egypt. Benefits to the Dental interns: - Challenge the knowledge of the intern dentists regarding caries risk assessment. - Encourage the concept of minimally invasive dentistry to be applied in clinical practice. - Accurate caries risk assessment in patients can guide clinician to give attention of their resources to high risk patients. Benefits to the patients: - Will benefit from proper knowledge, attitude and practice of dentists, thus proper treatment will be provided. - Behavioral modification of patients toward oral hygiene practices. - Reducing patient risk of developing advanced disease and may even arrest disease process. Benefits to the Community: -Imparting knowledge of Caries risk assessment to dentists will benefit their patients especially high-caries risk patients by giving proper preventive interventions that help to reduce the expected elevated incidence and severity of caries in the future, therefore the whole community will benefit.
