Preventing cavities with tooth sealant and laser
Part of Mouth & dental clinical trials.
This study tests a new type of tooth sealant (a protective coating) applied to your teeth, with or without a special laser treatment first. The goal is to see which method better prevents cavities and keeps the sealant in place, which may help you avoid future tooth decay.

This study compares two types of protective coatings (sealants) that can be painted on your child's partially grown back molars to prevent cavities. We want to see which works better and if it's easier for the dentist to apply.
This study compares two ways of cleaning teeth before placing protective sealants (thin plastic coatings that prevent cavities) on children's permanent back teeth. It looks at whether a newer, gentler cleaning method ('guided biofilm therapy') helps the sealants stay in place longer than the traditional polishing method.
This study tests two gentle cavity treatments for children's permanent molars. It aims to find which method works best over two years.
This study tests a new method to treat cavities that reach the middle layer of a tooth. It may help repair the tooth with a liquid that hardens into a filling. If you have a back tooth with a cavity that hasn't been filled yet, you might be eligible to join.
This study tests whether using a laser or a special rinse (chlorhexidine) to clean cavities before filling them changes the bacteria in your mouth. The goal is to see which cleaning method is better for keeping your tooth healthy.
This study tests whether rinsing off or blotting dry a special silver fluoride liquid before placing a tooth sealant helps the sealant last longer on molars affected by a common condition called molar-incisor hypomineralization. The goal is to find the best way to protect these teeth from cavities.
