Filter by:The aim of this study is to evaluate the remineralizing capacity of Gum Arabic varnish and its implementation into clinical practice.
Background: Early childhood caries (tooth decay, ECC) affected 55% 5-year-old Hong Kong children, and 70% of these children had gross destruction of the upper anterior teeth with negative long-term impacts on health and quality of life. The existing standard of care for prevention of ECC, topical application of 5% sodium fluoride (NaF) varnish, is inadequate. In Hong Kong and other parts of the world, 38% silver diamine fluoride (SDF) solution, applied topically to cavities, is used to arrest ECC. Work published by our research group suggests it likely also has a preventive effect of ECC. Moreover, SDF has been shown to be preventive in tooth decay in permanent teeth. Nevertheless, no pivotal clinical trial has been performed to support a change in usual practice. Aim: This is a Phase II single-centre randomized, double-blind, active-controlled, parallel-group pragmatic trial with two arms to assess the effectiveness of 38% SDF and 5% NaF in preventing new caries lesions in primary anterior teeth. Methods: 688 three-year-old kindergarten children who are healthy will be recruited, stratified by school, and block randomized to receive either 38% SDF (treatment group) or 5% NaF (standard treatment group) therapy on primary upper anterior teeth. This sample size is sufficient for a superiority trial with power at 90%, allowing for a 15% dropout rate. The primary outcome is the number of sound tooth surfaces that become cavitated caries per child at 12-month follow-up. The secondary outcome is the number of carious tooth surfaces developed after baseline that become arrested at 12-month for each child. Dental examinations for the status of caries (active or arrested) will be conducted by the same calibrated examiner. The examiner, children and children's parents will be blind to treatment allocation. Parents will be surveyed to study the children's oral health-related behaviours and socioeconomic backgrounds, which will allow the adjustment for effect modification. Possible results and implications: If the results are as anticipated, it will help change the standard of care for caries prevention. If adopted in Hong Kong, SDF therapy will prevent 20,800 (13% of the 160,000) kindergarten children from having caries developed in their anterior teeth, thus reduce significantly the burden of ECC of the children and related stress of their family. Moreover, the results will be widely available and increase adoption of SDF in other countries to reduce the global burden of ECC among children.
This study will be conducted to evaluate: 1. The remineralization potential of natural agents (egg shell powder and clove extract) versus bioadhesive polymers (carbopol and carboxymethyl cellulose) with or without PH cycling using microhardness test. 2. The clinical efficacy of all agents in patients with early carious lesions.
Pregnant women - living in thecatchment area of a public dental clinic with known higher caries experience and generally lower socioeconomical status than at other dental clinics in the Region - are recruited for the study. Repeated information and surveys of dental knowledge, dental habits and medical conditions etc. is sample. Before birth, one month after birth, and 12 and 18 months after birth of the Child, the mother repeatedly answers questionnaires and recieves information about dental care. At 18 months,and at the 3- and 6-year dental examinations the caries experience dmft/deft is registered. All Children and accompanying parent receives an individual caries preventive program between the examinations. Evaluation will be focused on possible caries sreduction and Health econimic aspects of the interventions.
The present study aimed to compare the remineralisation capacity of white spot enamel lesions between two commercially available tooth pastes (Remin Pro and MI PASTE PLUS), applied at home twice a day on the anterior upper primary teeth by the patient and parents.
The aim of this clinical study is to compare and evaluate the Success of Selective Caries vs Stepwise Caries Removal Techniques in treatment of dental caries.
Clinical trial to compare non-invasive and minimally-invasive therapies on the progression of the caries lesions. Clinical investigation of resin infiltration versus sodium fluoride (5% NaF) varnish application.
This is an investigator initiated randomized double-blind pilot study at the UCSF Pediatric Dental Clinics to compare effectiveness of a new toothpaste Livionex Dental Gel with a standard children's toothpaste containing 1500 ppm fluoride in reducing dental plaque and caries in healthy and well children every 3 months for up to 12 months.
The aim of the present study is to evaluate both Hall technique and atraumatic restorative technique in comparison to the conventional restorative technique in the management of carious lesions in primary molars.
The study is a randomized clinical trial that assesses the clinical success and the antibacterial effect on carious dentine of glass ionomer when modified with Chitosan and/or Titanium dioxide nano particles vs the control group of modification with Chlorhexidine as control when used in primary molars
