Phase: Phase 3
Study type: Interventional

The objective of this clinical research study is to evaluate the stain removal efficacy of a toothpaste containing stannous fluoride as compared to negative control toothpaste in adults.

NCT ID: NCT06125132 Recruiting - Tooth Discoloration Clinical Trials

Evaluation of 2-year Clinical Performance of Two Different Single Color Universal Composite Resin Restorative Materials.

Start date: October 1, 2023
Phase: N/A
Study type: Interventional

Dentists have recently preferred to use composite materials and restorative techniques that allow the use of simplified clinical protocols in order to reduce the time the patient spends in the dentist's chair and minimize technical sensitivity. Color selection in the clinic is a very sensitive process and is affected by environmental factors and operator-related variables. This has led to the development of single-color universal composite resins that aim to facilitate color selection. These materials have a universal opacity and several Vita shades and are recommended by manufacturers to be used in a single color layer that can match different tooth colors. In recent years, monochromatic universal composites have been developed that are supposed to be compatible with all Vita Classic Scale shades from A1 to D4. Manufacturers report that single-color universal composites can be applied to teeth of all colors without using the layering technique using different color composites. Therefore, the aim of this study is to compare the clinical performance of 2 different single-color universal composite resin materials (OMNICHROMA and Zenchroma) in the restoration of non-carious cervical lesions with the control group (Filtek Z250, 3M), which is a multi-color composite resin material, using modified US Public Health Service (USPHS) and World Dental Federation (FDI) criteria.

NCT ID: NCT05998980 Completed - Dental Diseases Clinical Trials

6-year Clinical Performance of Prefabricated and Composite Veneers ( Componeer)

Start date: July 1, 2016
Phase: N/A
Study type: Interventional

The aim of this study is to compare the clinical performance of composite veneers performed in two different ways, indirect and direct methods over a period of 6-year. 30 volunteer patients without systemic diseases and who applied to Ege University School of Dentistry for the esthetic restoration of their anterior diastema (gap) were selected according to inclusion and exclusion criteria. The closure of 102 diastema was randomly performed with prefabricated composite resin veneers (n=15; indirect method- Componeer, Coltène, Altstätten, Switzerland) or direct composite resin veneers (n=15; direct method- Essentia, GC, Japan). These restorations were clinically evaluated at baseline, 1-2-6-year by two experienced and blind examiners according to modified Ryge criteria (USPHS criteria). Color match, marginal discoloration, anatomic form, marginal adaptation, secondary caries, surface roughness, retention, and polishing retention were evaluated for that purpose. Statistical analysis was performed with McNemar and Chi-square tests (p<0.05).

NCT ID: NCT05984472 Completed - Dental Diseases Clinical Trials

3-year Clinical Performance of Prefabricated and Composite Veneers

Edelweiss
Start date: January 15, 2019
Phase: N/A
Study type: Interventional

The aim of this study was to evaluate the clinical performances of Edelweiss prefabricated veneers and direct resin composite restorations (Ceram-X Duo SphereTec) performed with U- veneer transparent templates used for anterior diastema closure and tooth reshaping over 3-year. The patient group consisted of individuals who applied for aesthetic complaints on their anterior teeth. 21 volunteer individuals without systemic disease were included in the study. Patients were randomly selected for each group. In Group 1; 38 teeth (10 patients) were restored with Edelweiss prefabricated veneers (Edelweiss Dentistry) in combination with Edelweiss nanohybrid resin composite (Edelweiss Dentistry) and Prime&Bond Universal (Dentsply Sirona) adhesive system. In Group 2; 36 teeth (11 patients) were restored with Ceram-X Duo SphereTec (Dentsply Sirona) resin composite in combination with U- veneer (Ultradent) transparent templates and Prime&Bond Universal adhesive systems. Properties of the restorations were evaluated at baseline, 6, 12, 24, and 36 months using Modified Ryge Criteria (USPHS Criteria). Data were evaluated using Chi-Square and Fisher's Exact tests (p=0.05).

NCT ID: NCT05938400 Completed - Clinical trials for Endodontically Treated Teeth

Start date: July 2, 2023
Phase: N/A
Study type: Interventional

This randomized controlled trial is to clinically assess and compare impression quality of polyvinylsiloxane impression material using one step (experimental) and two step (control) impression techniques and its effect on marginal fit of prosthesis and proximal contact of prosthesis.
