Filter by:The study is a multi-site, double blind, parallel arm, community-based randomized controlled trial (phase III RCT) to evaluate the effectiveness of new referral approaches to increase receipt of dental care among inner-city urban and rural elementary school children who were screened at school and have restorative treatment needs. The study has 5 arms: The experimental intervention is the use of a theoretically driven CSM referral letter alone, the letter plus a Dental Information Guide, a reduced CSM referral letter alone, or a reduced CSM referral letter plus a reduced Dental Information Guide. The control strategy is the use of a standard referral letter. All participating K-4 grade children will receive a screening at the beginning of the school year and at the study end point 7 months later to determine if the child received dental care. Due to lower than expected enrollment in both the Ohio and Washington sites, a second year of recruitment was added to include Bedford School District and East Cleveland School District (only KG and other grades if they did not enroll in the first year). The same study procedures, schedule and design was utilized for the second year of recruitment. The primary aim is to evaluate the effectiveness of experimental (new) versus standard referral approach given to parents/caregivers in increasing receipt of dental care among their children in grades K-4. The secondary aim is to assess changes in parent/caregiver illness representation/perception and behavioral intention between enrollment (beginning of school year) and follow-up (end of school year) to understand the underlying mechanisms of the new vs. standard referral approach that result in receipt of dental care. The hypothesis is that CSM-based interventions will increase receipt of dental care compared to the standard referral letter.
This study aimed to evaluate the clinical performance of a novel vitro-ceramic biomaterial (Biosilicate®) as treatment of caries-affected dentin in posterior resin restorations. A total of 94 restorations of 66 participants were selected and assigned at random into four groups: 1 (Biosilicate / Two-step etch and rinse system), 2 (Control / Two-step etch and rinse system), 3 (Biosilicate / Two-step self-etching system) and 4 (Control / Two-step self-etching system). Two operators carried out the adhesive protocols and restored the cavities with a nano-hybrid resin composite (IPS Empress, Ivoclar) using the incremental technique. Participants were recalled at one week, 6, 12 and 18 months for clinical evaluation performed by two blinders and calibrated examiners according FDI criteria.
Background: Tooth decay in children (Early childhood caries, or ECC) is a common childhood disease. Poor dentition significantly affects the nutrition, growth, development and general health of children. Conventional dental care for ECC is neither affordable nor accessible, particularly for the disadvantaged communities. Silver diamine fluoride (SDF) is a safe, cost-effective caries-arresting agent that appears to conform to the World Health Organization's Millennium Goals. SDF is commercially available at 38% and 12%, and topically used yearly or half-yearly to arrest ECC. The SDF regimens used for ECC treatment lack an evidence base. Therefore it is necessary to find the most suitable SDF concentration and application interval to arrest ECC. The purpose of this randomised controlled trial is to compare the efficacy of two commercially available SDF solutions at pre-prepared concentrations of 38% and 12% when applied at yearly or half-yearly intervals over 36 months in arresting caries in primary teeth. Methods / Design: This double-blinded study has recruited 888 kindergarten children aged 3-4 years with caries. The sample size is sufficient for the appropriate statistical analyses. The children were classified into high and low caries rates and equally allocated into four groups for the caries treatment: Group A - semi-annual application of 12% SDF; Group B - annual application of 12% SDF; Group C - semi-annual application of 38% SDF; Group D - annual application of 38% SDF. The children will be followed for 36 months in their kindergartens until they enter primary school. Clinical examinations at 6-month intervals will be conducted to assess whether the caries are arrested. Information on confounding factors, such as oral hygiene habits and the use of other fluoride agents, will be collected through a parental questionnaire at the baseline and follow-ups. Discussion: This study will help determine the most suitable SDF concentration and application interval to arrest caries in children. Because SDF use for caries arrest is painless, simple, and low-cost, it can be widely recommended and promoted for caries control in young children or those with difficulty accessing and affording conventional dental care. The applicability of the findings and their impact on public health would be immense.
The aim of this study is to evaluate the survival rate and the cost-effectiveness of occlusal-ART restorations using three GIC brands (Fuji IX, GC Europe; Maxxion R, FGM; Vitro Molar, DFL) in primary molars.
Children will be recruited from the pediatric dentistry clinic of Marquette University at their first or recall appointment and will be asked to fill a questionnaire regarding their dietary habits. Afterwards a dietary analysis will be performed using a computer software, developed for this study and dietary instructions will be given to the children.
The fact that dental caries remains a major public health problem mandates that oral-health researchers explore new strategies for assessment of caries risk, as well as for caries prevention and management. Dental caries occurs when acids produced by bacterial glycolysis of dietary carbohydrates causes demineralization of the tooth enamel. A major focus of caries research has been on identifying and characterizing acid-generating bacteria and the mechanisms of acid resistance. The purpose of this study is to investigate the type of bacteria that grows in the mouth and on teeth.
Demineralisation and white-spot caries often occures during MB treatment. While resin infiltration has been proved to stop progression of enamel demineralisation, there is still a paucity of information in the literature concerning the best time point of infiltration: During or following MB treatment. Infiltration during treatment requires debonding respective brackets prior to infiltration, with subsequent re-bonding. In terms of preventing enamel damages by progression of demineralisation and enamel damages by de-bonding, it is unclear whether it was better to infiltrate enamel immediately, or to better postpone until completion of MB treatment. This study thus aimes to evaluate if resin infiltration can prevent enamel damage due to bracket de-bonding.
The proposed test is intended to enable dentists to differentiate between cavitated and non-cavitated tooth decay in the areas where teeth are in contact (interproximal surfaces). In these areas, dentists cannot visually inspect for caries, and currently bitewing X-rays (BWs) only correctly detect the presence of enamel decay 15-25% of the time. This low sensitivity can lead to late treatment resulting in unnecessarily large fillings, crowns, pain, root canals, and possible later loss of teeth.
The objective of this clinical study is to evaluate whether the use of the new CO2 - 9.3μm short-pulsed laser increases the caries resistance of occlusal pit and fissure surfaces in patients in addition to fluoride therapy. This will be quantified by visual exams with the International Caries Detection and Assessment System (ICDAS II), SOPROLIFE daylight and blue fluorescence, and DIAGNOdent Laser Light-induced Fluorescence. This is a randomized, single blind, prospective, split mouth controlled, clinical trial over 12 months.
The purpose of this study is to determine whether Fluoride varnish + calcium (Clinpro White Varnish) and polipeptide solution (Curodont Repair) are effective in the treatment of remineralization therapy. The investigators will diagnose their alone or in combination effects on white spot lesions. Aesthetics (tooth-colored), remineralization, microbiological effects will be evaluated separately. Spectrophotometer (Vita Easy Shade) , Quantitative Light Fluorescence (QLF), Diagnodent(Cavo Diagnodent) and culture methods in microbiology laboratories are used for aesthetic, remineralization and microbiological assessments. The measurements will be made baseline, 6 weeks, 3 months and 6 months later after the applications and recorded.
