Painless cavity filling: new tools vs traditional drill
Part of Mouth & dental clinical trials.
This trial compares two newer methods for removing tooth decay (smart burs and a dissolving gel called Carisolv) to the traditional drill, to see which causes less pain during the procedure. It may help find a more comfortable way to treat cavities.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 45 years old.
- You have at least one cavity in a lower back tooth that has reached the dentin (the layer under the enamel) but has not caused pain.
- The cavity must be clearly visible and feel soft or leathery when touched with a dental probe.
- An X-ray must show a clear layer of healthy dentin between the cavity and the nerve (pulp).
- You are not pregnant, and you do not have heart disease, diabetes, high blood pressure, or severe gum disease.
- You have not had any signs of nerve damage (like pain, swelling, or no response to cold) in the affected tooth.

This trial compares a gentle chemical method for removing tooth decay with the traditional drilling method. The goal is to see which approach causes less anxiety, especially for people who are nervous about dental procedures.
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 study compares a new gel that softens tooth decay to the traditional drilling method for removing cavities in baby molars. If your child has a large cavity in a back tooth, they may be able to get treatment with less noise and vibration.
This study compares two ways of removing deep cavities in permanent back teeth to see which one keeps the tooth healthier. If you have a deep cavity that isn't causing constant pain, this trial may help preserve your natural tooth.
This study tests two cavity disinfectants to see which one better reduces pain and improves healing after removing deep decay from back teeth. It is for adults with deep cavities in their lower molars that are still alive (not needing a root canal).
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.
