4 Clinical Trials for Various Conditions
The main objective of this study is to determine the feasibility of optimizing the IMRT treatment plan based on dosimeter measurements of mucosal radiation dose adjacent to the dental fillings to reduce such dose to \< 35 Gy without compromising tumor coverage and/or increasing the dose to the remaining oral cavity or nearby parotid glands.
Head and Neck Cancer
The purpose of this study is to determine whether there are detectable health effects of low-level mercury exposure (from normal exposure to mercury-containing dental fillings) in the known target organs/systems affected by elemental mercury exposure.
Caries, Dental
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.
Cavities of Teeth, Dental Decay
The purpose of this study is to determine whether a new tooth-colored composite material is effective for load-bearing dental fillings.
