Dentin caries

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 study compares two ways to treat deep cavities in young permanent teeth without exposing the nerve. In selective excavation, the dentist removes only the outer decay and seals the tooth. In stepwise excavation, they place a temporary filling first and remove more decay a few…

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 study tests a special tooth-colored filling called alkasite composite (Cention Forte) for baby molars that have had pulp treatment. Twenty-five healthy children with deep cavities received this filling. Researchers are checking how well the fillings hold up over time using s…

This study tests whether using a diode laser before placing a special filling material (Biodentine) helps preserve more healthy tooth and reduces staining compared to using Biodentine alone. 48 adults with deep cavities in permanent back teeth are being treated and followed with …

This study tests three materials—amniotic membrane, mineral trioxide aggregate putty, and biodentine—for treating deep cavities in children's permanent molars that are still growing. The goal is to help the tooth root finish developing and avoid root canal or extraction. Seventy-…

This study tests whether a virtual reality (VR) game can lower anxiety and pain in children aged 6 to 10 during their first dental treatment. Half of the 88 kids will wear VR glasses showing an interactive game that explains each step, while the other half gets the standard 'tell…
