8 Clinical Trials for Various Conditions
This study is to determine if a new bone adhesive is useful in stabilizing dental tooth implants. Data collected from the study will examine the strength, performance, and the safety of the material.
Purpose: To evaluate the performance of several dental adhesives used for bonding tooth-colored fillings to teeth 6 years after the fillings have been placed. Participants: Subjects which had participated in the study entitled "Clinical Evaluation of New Total-Etch and Self-Etch Dental Adhesives" (IRB Study #07-0673). Procedures (methods): Fillings that had been placed 6 years ago will be evaluated by a direct, visual examination. Close-up intra-oral clinical photographs of each filling will be made. An impression of the filling may be obtained. The specific study aim of this 6-year recall of the patients treated in IRB Study #07-0673 is to evaluate the fillings placed according to the following characteristics: Retention; Color match; Cavosurface margin discoloration; Secondary caries; Anatomic form; Marginal adaptation and/or integrity; Post-operative sensitivity.
The purpose of this study is to compare the clinical performance of three dental adhesive systems used to bond Class V cavity fillings in adult teeth.
This is a prospective, controlled, within-subject, randomized, single-center study comparing Scotchbond Universal Plus and Scotchbond Universal adhesives when used with Filtek restorative. The study will enroll a minimum of 46 Subjects with Class-V non-carious cervical lesion (NCCL) on a minimum of two teeth.
This research study is looking at a new bond-promoting substance (a dental adhesive called 3M™ Scotchbond™ Universal Plus Adhesive) used between the tooth and dental restoration (filling). This study will evaluate whether Scotchbond™ Universal Plus Adhesive (SBU+) is as effective at bonding dental fillings as Scotchbond™ Universal Adhesive (SBU) for preparation of posterior Class I and Class II restorations in adult patients. Participants must have at least two (2) back teeth that need a filling either on the chewing surface alone (Class I) and/or on the chewing surface and between your teeth (Class II). One tooth will be restored using SBU+ and the other tooth will be restored using SBU adhesive, both filled using Filtek™ Universal Restorative as the filling material.
The purpose of this prospective clinical trial will be to evaluate the efficacy of an FDA approved and marketed universal dental adhesive formulation in adult noncarious cervical lesions using self-etch and selective etch approaches. The hypothesis is that using a selective enamel etch with this universal adhesive will enhance the restoration margin performance.
To compare a newly developed filling composite to a current filling composite system. Two restorations will be placed in each subject, one using system A and one using system B. The first system listed in the randomization pair will be placed on first tooth (#4-#13), and the second system on 2nd tooth (#4-#13). The same three researchers will be responsible for placement of all the restorations.
Study hypothesis: Etching the enamel followed by use of a self-etching adhesive on enamel and dentin is as effective as a one-step etch and rinse approach.
