Filter by:The purpose of this study is to evaluate and compare the clinical retention of a resin-based fissure sealant placed with prior application of etch-and-rinse and self-etch modes of universal adhesives.
Currently, the real scope of sealants (AS) is poorly documented in temporary dentition and its effectiveness has not been demonstrated. Yet it seems reasonable that the AS in temporary dentition could slow the specific development of carious lesions in early childhood. In addition, this non-invasive approach could delay the conventional food and thus save financial costs for more complex treatments. Finally, the installation of AS could afford, as demonstrated in adult teeth, lowering the cariogenic bacteria prevalence engaged in the caries process.
This study will examine the clinical performance of Class II restorations over a three year period with 3 composite resins - a conventional composite resin, a flowable composite resin and a bulk placed and cured composite resin.
The aim of this clinical trial was to compare the clinical performances of a glass ionomer restorative system with a micro hybrid resin based composite in class I and class II cavities. A total of 140 (80 class I and 60 class II) lesions in 59 patients were restored with a glass ionomer restorative system (Equia) or a micro hybrid composite(Gradia Direct). Restorations were evaluated at baseline and yearly during 6 years according to the modified-USPHS criteria. Data were analyzed with Cohcran's Q and McNemar's tests (p<0.05).
The aim of this randomized, prospective clinical study was to compare the clinical performance of a universal light-curing, ultra-fine particle hybrid composite with a new version of this product produced by the same manufacturer in Class 1 and Class 2 lesions.
This study is observational only and is intended to evaluate changes in the makeup and function of bacteria naturally present in the mouth during treatment with braces to straighten teeth.
Despite the availability of free health dental service in Sri Lanka, the prevalence and severity of dental caries among 6year old school children stand at a very high level according to the results of national oral health survey in 1983/84, 94/95 and 2002/2003. Professional fluoride varnish application has become popular as variety of studies has found that it is an efficient method in reducing dental caries. The simplicity of its application makes it very suitable and practical for use in dental clinics and outreach dental services, especially in young children. Aim of this study is to evaluate the cost effectiveness of 6 monthly application of sodium fluoride varnish in prevention of dental caries in permanent incisors and molars in children between 6 and 7 years in a suburban setting in Sri Lanka. This will be a double-blind, randomized controlled trial. A sample of school children (6-7 years) will be randomized into varnish and control groups. All the children will receive routine caries preventive measures of oral hygiene instructions, dietary advice and professional cleaning. Children in varnish group will receive fluoride varnish professionally applied after prophylaxis every 6 months. Clinical examinations of all children will be performed at the beginning of the study and 1 year and 2 years later. All the caries at the dentinal level of both groups will be stabilized with temporary restorations at the beginning. During this period, each school will be visited four times at 6-month interval for recruitment, dental examinations, and fluoride varnish applications. Recruited children will be randomly assigned to either a treatment (5% NaF varnish) or a control group. Caries examinations will be conducted using the International Caries Detection and Assessment System (ICDAS). The cost for the dental team's school visits; cost involved in the treatment of dental caries throughout the course of the study in both groups will be evaluated and compared at the end of the study. The sample size is calculated as 160 each arm to detect 5% caries change with 80% power. Analysis The effect of intervention will be measured by number of caries prevented. New caries in the usual care and intervention group will be calculated after the completion of the study. The costs for intervention will be estimated. The costs will be estimated for the dental material, time for human resources and indirect costs.
A comparison of caries detection rates between conventional intraoral bitewing radiography and a stationary intraoral digital tomosynthesis (s-IOT) using a carbon nanotube X-ray source array. The secondary objective is to assess participants experience with the s-IOT device.
The aim of this study is to compare the effect of new bioactive dentine substitute (Biodentine) versus glass ionomer cement in very deep carious lesions clinically and radiographically using digital radiography in the terms of postoperative pain and biocompatibility to the pulp.
The aim of this study was to investigate the clinical effectiveness of direct resin composite restorations placed with different placement techniques (incremental or bulk) and with different flowable linings (conventional or bulk-fill flowable) used in open-sandwich technique, in endodontically treated Class II cavities (mesio-occlusal or disto-occlusal), in a randomized controlled comparison.
