Dentin caries

This Phase 2 trial tests whether a topical drug called KH001 can preserve the pulp (nerve) inside teeth with deep cavities. Adults with deep dentinal caries will receive either KH001 or a placebo applied to the cavity. The study tracks how many people develop irreversible pulpiti…

This study tests whether one or two applications of 38% silver fluoride can stop cavities in the baby teeth of children aged 4 to 6 years. Researchers compare a single treatment against two treatments given three months apart, and also measure how the children's oral health affec…

This study tests whether a robot can place dental implants more accurately than a computer-guided navigation system in the front upper jaw. Twenty-four adults needing an implant will be randomly assigned to one of the two methods. The main goal is to see which approach achieves b…

This study tests a new material made from treated dentin and calcium silicate for treating deep cavities that have reached the tooth's nerve. The goal is to see if it can keep the nerve healthy better than the current standard material. Fifty-six people aged 14 to 35 with deep ca…

This study tests a new material called NeoPutty MTA against a standard chemical, formocresol, for treating deep cavities in children's back baby teeth. About 68 kids aged 4 to 9 will get one of the two treatments to save the tooth and prevent pain or infection. Researchers will c…

This study tests two cavity-stopping liquids in 60 children aged 3-5 with active tooth decay. One is a well-known treatment that turns cavities black; the other is a newer version that may avoid staining. Researchers will check which works better over 12 months, and ask parents a…

This study tests whether a new bioactive filling material helps teeth repair themselves after deep cavities are removed. 66 adults with deep decay will get either the bioactive filling or a standard one. Researchers will check for new tooth layer formation and pain over 2 years.

This study compares two dental treatments for teeth with deep cavities and reversible pulpitis (early nerve inflammation). One treatment caps the exposed nerve directly, while the other removes a small part of the nerve before capping. The study will include 138 people aged 15-40…

This study compares two cavity removal methods in 144 adults with deep cavities and reversible pulpitis (tooth nerve inflammation that can heal). One method removes all decay, the other leaves some near the nerve. Researchers will check pain, tooth vitality, and X-rays over 12 mo…

This study tests a handheld scanner that uses safe near-infrared light to find early cavities without radiation. Fifty adults scheduled for a tooth extraction will get an extra 5-minute scan before their procedure. The scanner's results will be compared to standard X-rays and vis…
