Filter by:Dental materials with antibacterial properties can prevent the harmful effects caused by oral cariogenic bacteria. This double-blind controlled clinical trial evaluated the performance of antibacterial cement for sealing infected dentin in atraumatic restorations of primary molars.
Nearly half of the 12-year-old children in China have dental caries (tooth decay) and most of the lesions are in the fissures of the first permanent molars. This study aims to investigate the effectiveness of three methods in preventing fissure caries in permanent teeth in Chinese children, namely resin fissure sealant, sodium fluoride varnish, and silver diamine fluoride solution. The cost-effectiveness of these methods will also be compared. About 400 children, aged 8 to 9 years, will be recruited. Clinical examination of the children will be conducted in school using portable dental lights and instruments to identify teeth that need caries prevention. The children will be randomly allocated to one of the three test or the control groups. Treatments will be provided in the study primary schools according to standard clinical protocols. Follow-up examinations will be carried out every six months for 30 months to assess whether the preventive methods are successful, i.e. no dental caries develops in the treated teeth. The findings of this study will be of great value to dentists and public health authorities in deciding on the most appropriate dental caries prevention programme for school children in China and other developing countries.
Sealants have been shown to be the most effective caries preventive measure in permanent dentition. Sealants of the primary molars soon after they erupt would reduce the total caries experience of the primary teeth of the children and could possibly also postpone the caries process in the permanent dentition. The aim of this study is to measure the caries preventive effect of sealants in primary molars. The specific objectives are: 1) to compare the number of new caries experience teeth and surfaces among the intervention group of 4-years old pre-school children during the 1 year follow-up period, 2) to compare the preventive effect of sealants with fluoride varnish on the caries experience on the occlusal surfaces of the primary molars and on the total caries experience of all the primary and permanent teeth, 3) to test the feasibility of the sealant program in one kindergarten in Kuwait city.
The purpose of this study was to compare with a clinical randomized controlled split-mouth design study the changes in the therapeutic effect of infiltrating versus sealing proximal caries lesions and placebo treatment after 1, 2 and 3 years. The outcome was lesion progression, evaluated by radiographic techniques.
Study hypothesis: Etching the enamel followed by use of a self-etching adhesive on enamel and dentin is as effective as a one-step etch and rinse approach.
Study hypothesis: a new, low polymerization stress flowable composite performs no differently to a conventional, highly filled composite filling material when used as a restorative in small cavities in back teeth. Study will evaluate the clinical performance of a low shrinking flowable composite filling material, compared with a conventional, highly filled composite restorative when used to permanently fill small cavities in molar and premolar teeth in adult patients.
The goal of this study is to address the effectiveness of a modified cavity prevention protocol for 5-9 year-old children which emphasizes better diet modification, more frequent professional fluoride applications, and xylitol product usage based on individual risk status in a 1-year randomized controlled clinical trial in the University of California, San Francisco (UCSF) Tenderloin Community Pediatric Dental Clinic. The investigators hypothesize that the regimen will help to reduce new cavities in children who are at risk for dental cavities.
The purpose of this study will allow us to observe and follow the subjects' treatment from DPBRN Prevalence of Questionable Occlusal Caries Lesions Study over a 24 month period.
This study focused on improving the quality of dental care by fostering movement of the latest scientific advances into daily clinical practice.
Providing child nutrition information is a major goal of every pediatric well-child visit. Unfortunately, due to a wide array of issues, doing this effectively during clinic visits is challenging and insufficient. It is because of this that some have looked for innovative ways to enhance the delivery of this information. One such way is the use of touch screen computer programs containing nutritional information. Several studies have documented the value of patients receiving health information in such a manner. Nonetheless, the use of this medium has not been well studied in Spanish-speaking care providers of young children. The investigators recently conducted a study that evaluated user's perception of the usability of such technology, finding that most users thought that the touchscreen was easy to use, despite their low computer confidence levels. The investigators also evaluated the impact of using nutrition modules on user's nutrition knowledge, finding that immediately after use; participant's nutrition knowledge was improved. I now propose to evaluate this technology further through a 4 armed randomized controlled trial. The goal here is to evaluate the longer term impact of the educational modules on nutrition knowledge and the impact, if any, of additional web access to the modules, on longer term knowledge. A secondary goal is to better understand nutritional habits in this population and perceptions of weight.
