Active clinical trials for "Dental Caries"

Single-blind study to evaluate whether C16G2 Strip administered in multiple doses can effectively kill the bacteria in the oral cavity that cause dental caries..

An open-label and single-blind phase 2 study to evaluate the oral microbiology, safety and tolerability of multiple C16G2 Varnish and Strip applications in male and female dental subjects 12-75 years of age. The study will compare multiple study drug administrations of C16G2 Varnish and/or C16G2 Strip in three study arms. In Study Arm 1 eight subjects will be enrolled in an open-label manner and will receive a daily dose of C16G2 Varnish application over 3 days followed by 14 doses of C16G2 Strip administered over 7 days. Following the three C16G2 Varnish applications, each subject will receive 7 days of AM and PM dosing with C16G2 Strip and will be followed for microbiology for up to 2 months after the last study drug administration. Study Arm 2 will enroll 12 subjects in a single-blind manner. Subjects will receive four C16G2 Varnish or Placebo applications over 7 days, followed by 3 additional weekly varnish administrations. Subjects will be followed for microbiology for up to 2 months after the last study drug administration.The treatment allocation will be 1:1 (6 subjects receiving C16G2 Varnish, 6 subjects receiving Placebo). Study Arm 3 will be initiated based on the Sponsor's review of all microbiology data up to two week post last study drug administration from Study Arm 2. If initiated, Study Arm 3 will enroll 6 subjects in an open-label manner. Subjects will receive daily single doses of C16G2 Varnish over 10 days, for a total of 10 doses and will be followed for microbiology for up to 2 months after the last study drug administration.

The teeth of the patients that meet inclusion criteria will be anesthetized, isolated with a rubber dam. Cavity opened using conventional high-speed rotary instruments. The central cariogenic biomass and the superficial parts of the necrotic dentine will be removed with round burs. Caries lesion will be completely removed in the enamel/dentin junction. The excavation procedure will be terminated as soon as the soft and wet dentine was removed and the remaining tissue was leathery but not hard on exploring. A dentinal sample will then be collected from the base of the cavity using sterile spoon excavator as a baseline for bacteriological assessment. Then, application of either intervention or control agent, another dentinal sample will be collected using a sterile excavator and transferred into sterile tubes and transferred to the laboratory for microbiological analysis. Filling of the cavity with resin composite restoration. All clinical procedures will be carried out at the same visit.

This study aimed to test whether sealing microcavitated ICDAS 3 carious lesions in permanent molars may be arrested by sealing using two different types of materials; a glass ionomer and a resin sealant. A Randomized controlled clinical trial was designed. Children between 6 and 12 years old were recruited and a total of 150 ICDAS 3 lesions in first permanent molars were allocated to one of the two arms of the study. Clinical and radiographic lesion progression were the main outcome. Integrity of the material and retention were secondary outcomes. A follow up period of 24 months with check-ups at 6 and 12 months was considered.

The research project "SEAL-DK" is focusing on advantages and disadvantages of two treatment strategies: non-invasive fissure sealing and invasive restorative treatment of manifest occlusal caries lesions in permanent teeth in children and adolescents. The purpose of the project is to promote the understanding of the possibilities of non-invasive treatment of occlusal caries lesions in the permanent dentition, and to increase the present knowledge about the optimal threshold for sealing or restoration, respectively, when treating such lesions. The project is carried out as a randomized study of the two treatment strategies: non-invasive versus invasive treatment of occlusal caries. When organizing the study, it is emphasized that no treatment shall be carried out, if conflicting the participating dentists' perception of clinically proper caries treatment, and that the results shall have a high reliability and consistency. The hypothesis is that caries progression can be stopped by non-invasive fissure sealing changing the threshold and postponing the time for invasive restoration.

The aim of this, two-arm, parallel group, patient-randomised controlled, superiority trial is to evaluate the survival rate of approximal Atraumatic Restorative Treatment (ART) restorations compared to the Hall Technique (HT) placed in a school setting. The investigators will recruit 120 schoolchildren (5-10 years) with at least one occlusal-proximal carious lesion in primary molar. They will be randomized and treated following best-practice protocols to either receive an ART restoration using the high-viscosity glass ionomer cement (EQUIA Forte, capsules, GC Corp.) or a preformed metal crown placed using the HT (3M ESPE) cemented with glass ionomer luting cement (Fuji I Capsules, GC Corp.). Baseline measures and outcome data (at reviews over a three year period) will be assessed through participant report, clinical examination and parent report/ questionnaires.

The purpose of this study is to evaluate if C16G2 Gel administered over a certain period of time either with a toothbrush or a custom dental tray can effectively kill bacteria in the mouth that cause dental cavities.

The main purpose of this trial is to determine which material, between ceramic and composite, is best to manufacture dental inlays and onlays in the treatment of moderate dental substance losses, generally due to dental caries. Restorations will be done using direct Computer Assisted Design and Manufacturing (CAD-CAM). Another aim of this study is to determine which factors influence the success of these restorations.

To evaluate the efficacy of a papain-based gel in caries removal.

The purpose of this study is to determine whether two tooth-colored glass ionomer materials are effective for load-bearing dental fillings.
