NCT ID: NCT04929340 Suspended - Clinical trials for Dental Caries in Children

Prevention of Recurrent Caries With Lactobacilli PRECAL

Start date: May 1, 2017
Phase: N/A
Study type: Interventional

The aim of this study was to compare the effect of drops containing probiotic bacteria (Lactobacillus reuteri 17938, Lactobacillus reuteri PTA 5289, Biogaia AB, Sweden) on the incidence of dental caries with placebo drops in preschool children undergoing comprehensive restorative treatment under general anesthesia or conscious sedation. The project will be conducted at three specialist centers (Umeå University, Umeå, Sweden, Maxillo-facial unit, Halmstad Hospital, Sweden; Eastman Institute, Stockholm, Sweden) and employ a randomized placebo-controlled design with two parallel arms. The study will be performed double-blind and neither the parents nor the clinicians will be aware of the content of the drops. The follow-up period is one year.

NCT ID: NCT04213573 Suspended - Clinical trials for Dental Caries in Children

Efficacy of Silver Diamine Fluoride and Its Parental Perception

Start date: January 21, 2020
Phase: Phase 2/Phase 3
Study type: Interventional

This randomized clinical trial aims to compare the effectiveness of two topical fluoride application protocols, namely 38% silver diamine fluoride and sodium fluoride with added casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) in arresting dental caries in children.

NCT ID: NCT03827889 Suspended - Dental Caries Clinical Trials

Efficacy of Two Protocols for Applying Fluorine Varnish to Deciduous Teeth

CEPECO3
Start date: January 1, 2024
Phase: N/A
Study type: Interventional

Evidence that the data flow analysis tests, there are still no studies that show the clarity of the protocols of its application, including the interval and execution factors of applications, concentration of fluoridation and previous prophylaxis. That is, there are still large gaps regarding fluoride varnish applications. Thus, the objective of the present project is the selection of two protocols for application of fluid applications in active drugs in primary tooth enamel. The longitudinal follow-up will be performed in a period of 3, 6, 12, 18 and 24 months after the procedure. The progression of a subject will be evaluated clinically through the transition of ICDAS scores and assessment of the lesions (sound examination with superficial measurements) by visual examination, and the physician evaluates the efficacy and the ability to evaluate the therapeutic techniques and evaluation. treatment, cost and quality of life of participants

NCT ID: NCT03785730 Suspended - Dental Caries Clinical Trials

Non-restorative Cavity Control in Anterior Cavitated Caries Lesion of Primary Teeth

CEPECO2
Start date: April 30, 2019
Phase: N/A
Study type: Interventional

Background: Studies have questioned the necessity of restoring cavitated carious lesion on primary teeth, once the control of biofilm is the most important factor to arrest these lesions. This randomized clinical trial aimed to compare the survival of teeth treated with a non-restorative cavity control (NRCC) compared to resin composite restorations (RCR) on proximal carious lesion in anterior primary teeth, as well as the impact of these treatments on patient-centered outcomes. Methods: A randomized clinical trial with two parallels arms (1:1) will be conducted. Children between 3 and 6 years old will be selected from the Center of Clinic Research of Pediatric Dentistry of Ibirapuera University (UNIB), a dental trailer (FOUSP) located on Educational Complex Professor Carlos Osmarinho de Lima, the Pediatric Dentistry Clinic of Santa Cecília University and from the Pediatric Dentistry Clinic of University Center UNINOVAFAPI. One hundred and forty-eight teeth will be randomly distributed in two experimental groups: (1) Selective removal of carious tissue and RCR; or (2) NRCC through cavity enlargement using metallic sandpaper. The primary outcome will be tooth survival after 6, 12, 18, and 24 months. The duration and the cost of dental treatments will be considered for the estimation of the cost-effectiveness of the evaluated treatments. The discomfort reported by the participants will be measured after each treatment using the FIS scale. The participants' satisfaction and perception of the parents/legal guardians will be evaluated through questionnaires. For the primary outcome, Kaplan-Meier's survival and Long-Rank test will be used for comparison between the two groups. All the variables will be modeled by Cox regression with shared fragility. Significance will be considered at 5%.

NCT ID: NCT02568917 Suspended - Dental Caries Clinical Trials

Effectiveness of ART and Conventional Treatment - Practice-based Clinical Trial

Start date: August 2020
Phase: N/A
Study type: Interventional

Background: Dental caries is still a public health problem among Brazilian children and doubts still exist regarding the most effective restorative technique. The aim of this pragmatic randomized clinical trial is to evaluate the effectiveness of single and multiple-surfaces restorations performed following the Atraumatic Restorative Treatment (ART) premises compared with Conventional Treatment (CT) in primary and permanent teeth. Methods: A total of 1,214 5-to-13 years-old children with at least one single or multiple-surface dentin caries lesion in primary or permanent molars will be selected in the public schools of Barueri-SP. The participants will be randomly divided into 2 groups: CT (Filtek Bulk Fill - 3M) and ART (Ketac Molar Easy Mix - 3M) and treated by ten untrained dentists in a dental office inside the schools. The restorations will be evaluated after 6, 12 and 24 months by an independent trained and calibrated examiner. The restoration and tooth survival, the cost-effectiveness analysis between the two groups and the operator preference of the treatment regarding the techniques will be also evaluated. Kaplan-Meier survival analysis and log-rank test will be applied to the survival of restorations. All the average event rates in the two groups will be modelled and compared with a Cox proportional hazard shared frailty model since there is an operator cluster-effect. The significance level for all analyses will be 5%.
