Laser vs. rinse for cleaning cavities in back teeth
Part of Mouth & dental clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older
- You have a cavity on the biting surface of a back tooth (molar or premolar) that extends no deeper than the middle layer of the tooth (dentin)
- You have good oral hygiene (regular brushing and flossing)
- You have no symptoms of infection or nerve damage in the tooth (like pain, swelling, or an abscess)
- The tooth is not dead and touches the opposite tooth when you bite

Other trials that look related to this one.
This study tests whether sodium fluoride and chlorhexidine (a prescription mouthwash) change certain markers in saliva that may relate to tooth decay in children with cavities. The goal is to understand if these common dental treatments affect the body's natural cavity-fighting substances.
This study tests whether an Er:YAG laser can be used to prepare cavities in teeth that are already scheduled for removal. It will likely use teeth that are healthy or have early decay to compare the laser with traditional drilling, helping to understand if lasers are a painless and safe alternative.
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 trial compares two types of tooth-colored fillings for teeth with deep cavities that extend below the gumline. One filling material is designed to release minerals to help protect the tooth, while the other is a standard strong resin. The goal is to see which material works better for this kind of repair.
This study tests whether a special laser (Er,Cr:YSGG) can prevent cavities in the deep grooves of children's permanent back teeth. It is for children ages 6–12 who are calm during dental visits and have healthy, groove-filled molars without visible cavities.
This study tests a gentler way to treat deep cavities in back teeth by removing only the decayed part and filling with a special glass-based filling material. It aims to preserve more of your natural tooth and may reduce the need for more invasive procedures.
