NCT ID: NCT06377423 Completed - Dental Leakage Clinical Trials

Comparison Between Direct Composite and Indirect Ceramic Laminate Veneers in Multiple Diastema Closure Cases

Start date: August 1, 2021
Phase: N/A
Study type: Interventional

Thus, the present study aimed to evaluate the longevity of direct composite compared to indirect ceramic laminate veneers in multiple diastema closure cases using USPHS criteria. The formulated null hypothesis was that there is no significant difference in the clinical performance of direct composite and indirect ceramic laminate veneers in multiple diastema closure cases over two years.

NCT ID: NCT04515069 Completed - Clinical trials for Discoloration, Tooth

Survival of Hybrid Laminate Veneers Using Two Different Tooth Preparation Techniques:Randomized Clinical Trial

Start date: April 13, 2017
Phase: N/A
Study type: Interventional

The aim of this study was to evaluate the survival of laminate veneers constructed using a recent polymer-infiltrated ceramic network material following the aesthetic pre-evaluative temporary (APT) technique of tooth preparation in comparison to traditional technique.

NCT ID: NCT04244903 Recruiting - Clinical trials for Destructive Attachment of Labial Frenum

Prevalence of MLFA Types and MD in Egyptian Children With Erupted Canines

diastema

Phase:
Study type: Observational

Descriptive observational cross sectional study Outpatient at faculty of dentistry Cairo university pediatric dentistry department clinic with midline diastema and fully erupted canines will be examined and assess type of frenal attachment to see if correlation present or not

NCT ID: NCT03136276 Not yet recruiting - Tooth Discoloration Clinical Trials

One Year Clinical Evaluation of IPS Empress CAD Versus Polished Celtra Duo Ceramic Laminate Veneers

Start date: July 2017
Phase: N/A
Study type: Interventional

When restoring teeth with IPS Empress laminate veneers, fracture of restorations may occur. So, material with higher mechanical properties is required. Celtra Duo is a new material with glass ceramics infiltrated by 10% zirconia particles which increase the fracture resistance of the material.

NCT ID: NCT02893735 Completed - Diastema Clinical Trials

Clinical Comparison of Two Resin Composites on Diastema Closure and Reshaping at Four Years

Start date: December 2011
Phase: N/A
Study type: Interventional

The aim of this study was to evaluate the clinical performances of nano-hybrid resin composite systems used for anterior diastema closure and tooth reshaping at 4 years in service using FDI Criteria. Twenty-three patients with diastema problem were enrolled. Nano-hybrid resin composites to be used on each patient were randomly selected. Thirty-seven teeth (10 patients) were restored with Filtek-Z550 (3M/ESPE) in combination with Adper™ Single Bond 2 (3M/ESPE) in Group 1; whereas 39 teeth (13 patients) were restored with Charisma-Diamond (Heraeus Kulzer) in combination with Gluma2 Bond (Heraeus Kulzer) in Group 2, by two operators. Esthetic, functional and biological properties of the restorations were evaluated at baseline, 1-4 years using FDI Criteria establishing a score-range of 1-5. The data were evaluated using the Fisher's Chi-Square (p=0.05).
