Filter by:This is a double blind, cross-over, controlled clinical trial utilizing thirty (30) adults to evaluate remineralization of early caries lesions.
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.
This study is a randomized clinical trial lasting for 30 months. A total of 300 subjects will be recruited from social centres for elders located in different districts in Hong Kong. Baseline clinical examination will be conducted by a single calibrated examiner in the social centres using an intra-oral LED light, mouth mirrors and probes. Subjects will be randomly allocated into the three study groups and receive interventions accordingly. Follow-up examinations at 6-month intervals will be carried out to assess the clinical outcomes, i.e. whether new root caries has developed and whether the active root caries found at baseline have become arrested (remineralized and hardened) or not. Photographs of the arrested lesions will be taken to assess their colour. Results of this study will provide the much needed evidence to guide the dental professionals in Hong Kong and worldwide in deciding on the most appropriate intervention for the prevention and treatment of this common dental disease of the older adults.
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.
