This study compares two conservative methods for treating deep tooth decay that reaches close to the nerve. In one approach, dentists leave softer decayed tissue near the nerve; in the other, they remove more until firmer tissue remains. About 100 patients with deep decay in perm…

This trial compares two ways to treat a severely decayed tooth that has caused irreversible pulpitis, a painful condition where the tooth's inner pulp is inflamed. One method uses a standard solution to control bleeding after removing damaged pulp, while the other uses a diode la…

This study tests a procedure called pulpotomy, which removes damaged pulp tissue to save a tooth, in children under 14 with molar incisor hypomineralization (MIH) and deep decay. The goal is to see if this tooth-preserving approach can avoid root canals and keep the tooth functio…

This trial compares two dental procedures—direct pulp capping and partial pulpotomy—for treating permanent teeth with deep cavities that expose the pulp. Adults with deep caries and reversible pulpitis will be randomly assigned to one of the two procedures. The study will follow …

This study tests whether the level of a specific inflammatory marker (MMP9) in the dental pulp can predict the success of a full pulpotomy, a procedure that removes the inflamed pulp from the crown of a tooth and seals it with a special material. Adults with deep cavities causing…

This small pilot study tests two different stitching techniques during gum surgery to cover exposed tooth roots caused by gum recession. Seven healthy adults with multiple areas of gum recession will receive both techniques in different parts of their mouth. The goal is to see wh…
