Tooth extraction

This trial tests whether a graft made from a patient's own extracted tooth can preserve the jawbone that normally shrinks after tooth removal. Researchers compare four approaches: no graft, dentin graft alone, dentin graft combined with platelet-rich fibrin (PRF) from the patient…

This trial tests two bone-grafting materials placed around dental implants immediately after tooth extraction in the front upper jaw. One group receives a graft made from processed tooth dentin, while the other gets dentin mixed with a concentrate of the patient's own blood prote…

This study tested whether adding a bone growth protein (rhBMP-2) to dental implants placed right after tooth removal improves implant stability and preserves jawbone. Twenty-four adults with damaged upper front or premolar teeth received either the protein or standard implant pla…

This study tested whether a gel made from a patient's own blood (PRGF) can help preserve bone after a tooth extraction, compared to a standard cow-bone graft. Thirty adults who needed a tooth pulled and later a dental implant took part. Researchers measured bone changes with CT s…

This study tested two types of natural membranes used during dental implant surgery after a tooth is pulled. Forty adults with a non-restorable molar in the lower jaw received an implant right away, covered with either a membrane made from their own tooth or one made from their b…

This study tested whether using a patient's own extracted tooth as a bone graft (AMDG) works better than a synthetic material (β-TCP) or no graft at all for preserving the jawbone after tooth removal. Twenty-two adults who needed a maxillary premolar pulled received one of the th…

This study tested whether placing a thin bone layer (cortical lamina) over the extraction site helps preserve the jawbone's shape and size. Forty adults needing a tooth pulled were randomly assigned to get the lamina or standard care. After six months, bone changes were measured …

This completed pilot study tested two different IV drug combinations used to sedate people during wisdom tooth removal. One combo used ketamine, the other used propofol instead. Researchers measured how quickly patients recovered, whether they remembered the procedure, and how sa…

This study tested whether a special electronic syringe (Dentapen) causes less pain and stress during dental numbing shots compared to a regular syringe. Forty healthy adults getting teeth pulled for braces took part. Researchers measured pain using a 0-100 scale and stress by tra…

This study looked at 60 adults who needed a single tooth replaced right after extraction. Researchers compared two types of implant surfaces and whether adding low-level laser therapy helped. The goal was to see which approach gave the best implant stability and least bone loss o…

This study tested whether a Post-Dental Extraction Care Kit (PDEC-kit) helps patients better understand and follow care instructions after a tooth extraction, and whether it reduces anxiety. 208 adults having routine tooth removal were split into two groups: one received standard…

This study looked at two ways of teaching dental students how to evaluate patients before a tooth extraction. One group used an OSCE (a hands-on exam), the other used traditional methods. Researchers measured their clinical skills, anxiety, and satisfaction. The goal is to find b…

This study tested whether a computer-guided dynamic navigation system helps dentists place dental implants more accurately right after a tooth is pulled. Twenty healthy adults with a tooth that needed extraction and replacement received an implant using either dynamic navigation …

After a tooth is removed, a bone graft is often placed to prevent the bone from shrinking. This study tested whether hydrating the bone graft with dexamethasone (a steroid) instead of saline improves healing. 44 adults who needed a tooth extraction and planned dental implant took…
