Active clinical trials for "Dental Caries"

The aim of this study is to evaluate the effect of shortening the etching time on the 18-month clinical performance of resin composite restorations in primary molars after partial carious removal. This randomized clinical trial will include subjects (5-10 year-old children) selected at Pediatric Clinic of Federal University of Santa Maria. The sample will consist of 70 primary molars presenting active cavitated carious lesions (with radiographic involvement of the outer half of the dentin), located on the occlusal surface. The sample will be randomly divided into two groups according to the etching time of the dentin prior adhesive application (Adper Single Bond 2; 3M ESPE): recommend by manufacturers (15 seconds) and half-reduced etching time (7 seconds). The restorations will be clinically followed every 6 months for up to 18-month using the FDI criteria for clinical evaluation. Survival estimates for restoration longevity will be evaluated using the Kaplan-Meier method.

The sealing of fossae and fissures is an effective procedure in preventing occlusal caries lesions. However, there are gaps regarding its efficacy in the treatment of initial enamel lesions. In addition, there are no studies in the literature that have compared the longevity of sealings performed with the different sealants available in the market. Thus, the objective of this study is to evaluate the efficacy of fossae and fissures sealings performed with a low-cost resinous sealant in occlusal lesions in enamel in permanent and deciduous molars. This is a multicenter clinical study of non-inferiority, randomized, controlled, double blind (patient and operator) with 60 deciduous molars and 340 permanent molars of children 4 and 9 years of age. The sample unit will be the tooth, which will be randomized into two groups using a distributed randomization list in mixed envelopes that will be open only at the time of the procedure. The teeth allocated in the test group will be treated with the sealant preventâ; Those allocated in the control group will employ the Fluroshieldâ sealant. In both groups the procedure will follow the manufacturer's standards. The efficacy of the sealant will be evaluated by means of clinical and radiographic control at 6, 12 and 18 months after the procedure. Secondary outcomes, such as retention, cost, acceptability and quality of life, will also be evaluated.

The aim of the study is to assess the efficacy of a modified version of the behaviour management technique Latent inhibition in combination with Er:YAG laser for achieving reduction of dental anxiety in paediatric dental patients. The main objectives are to compare dental anxiety felt during the laser and conventional dental treatment. The outcomes will be dental anxiety assessment by a self-reported anxiety during treatment in both group as well as measurement of heart rate dynamics during the procedures.

•To investigate clinical and radiographic outcomes of Hall Technique and conventional restorative care using RMGIC in occulusoproximal carious lesions of primary molars in children.

This clinical trial will be conducted to compare the efficacy of grape seed extract oil versus sodium fluoride mouth wash in the management of remineralization in adult patients with white spot lesion over six months.

This Randomized Clinical Trial will be conducted to compare the efficacy of ethanolic extract of Aloe vera versus chlorhexidine cavity disinfectant in reducing total bacterial count of Streptococcus mutans (SM) and Lactobacilli (LB).

The study was designed to assess the effectiveness of conservation ridge preservation (horizontal and vertical dimension) after tooth extraction with and without combination of bone substitutes based on synthetic (calcium sulfate mixed with phosphate.

Atypical cavities, which involve more than two surfaces being one of them vestibular or lingual/palatine, are a challenge for restorative dentistry, since the risk of failure of the restorations are related to the number of surfaces involved. Thus, the objective of this project is to conduct a randomized clinical trial in order to evaluate the efficacy and patient-centered outcomes of a chemically-activated alkasite composite resin in atypical lesions of deciduous molars. Deciduous molars of children between 4 and 7 years of age with at least one atypical cavity lesion in deciduous molars will be selected for the ECR. The selected teeth will be randomly divided into two groups: Chemically activated composite resin Alkasite and resin-Modified glass ionomer cement. Clinical and radiographic follow-up of the lesions will be performed for 6 and 12 months. The efficacy of the treatments will be evaluated by the longevity of the restoring procedures and the arrestment of the caries lesions. Patient-centered outcomes will also be evaluated.

Atypical cavities, which involve more than two surfaces, one being buccal or lingual/palatal, are a challenge for restorative dentistry, since the risk of restorative failure is related to the number of surfaces involved. Thus, the purpose of this umbrella project is to conduct a randomized controlled trial (RCT) to evaluate the efficacy and patient-centered outcomes of a chemically activated composite alkasite resin in atypical deciduous molar lesions. Primary molars of children aged 4 to 7 years with at least one atypical cavitary lesion in primary molars will be selected for the RCT. The selected teeth will be randomly divided into: Alkasite chemically activated composite resin and Bulk fill composite resin. Clinical and radiographic follow-up of the lesions will be performed for 6 and 12 months. The effectiveness of the treatments will be evaluated by the longevity of the restorative procedures and paralysis of the lesions. Patient-centered outcomes will also be evaluated.

Permanent teeth with carious pulp exposure and indicated for full pulpotomy will be treated using three different materials using aseptic technique and will be subsequently followed up clinically and radiographically at 6 months, 1 year and yearly up to 5 years.
