Comparing tooth sensitivity after two types of molar fillings
Part of Mouth & dental clinical trials.
This study compares two types of tooth-colored fillings for back teeth with cavities. One is a newer 'bulk-fill' material placed in one layer, and the other is a traditional filling placed in thin layers. The goal is to see which one causes less tooth sensitivity after the filling is placed.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 40 years old.
- You have a cavity in a back tooth (first or second molar) that is on the biting surface.
- The cavity is about 4 mm deep (but not too deep).
- The tooth has no existing filling, no pain or sensitivity, and no signs of infection (confirmed by X-ray).
- You are not taking painkillers for the tooth, do not grind or clench your teeth, and do not have cracked tooth syndrome.

This study compares two types of tooth-colored filling materials for cavities on the chewing surface of back teeth. It aims to see which one works better for simple cavities that haven't reached the nerve.
This study compares three types of tooth-colored fillings for cavities between teeth. It aims to see which filling works best over 18 months, so you can keep your natural teeth healthy.
This study compares two types of tooth-colored filling materials used to repair cavities in back teeth. The goal is to see which material works better and lasts longer, helping you keep your natural teeth healthy.
This study compares a newer type of tooth-colored filling material (called bulk-fill composite) to standard fillings for cavities in back teeth. It tests how well the fillings hold up over time, which could help you get a filling that lasts longer.
This study tests two types of dental fillings for deep cavities to see which one helps the tooth form a protective layer over the nerve. It aims to find a better way to treat cavities that are close to the nerve, potentially avoiding more invasive procedures.
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.
