Evaluation of Guided Tissue Regeneration Following Third Molar Extraction by Bone Scintigraphy Using Tc99m-MDP

Extraction of impacted third molars is a well-established and documented procedure. Guided tissue regeneration can be used to aid in wound healing and increase osseous tissue formation. To assess the regenerative treatment outcome, several variables are routinely used; these include primarily histology and direct measurement of bone. Other proxy measurements, such as radiographic analysis, clinical attachment level and periodontal pocket depth are commonly used. This report describes the use of an ePTFE membrane following extraction of an impacted wisdom tooth, and the subsequent use of bone scan using Tc99m-Methylene Diphosphonate (MDP) to monitor the regenerative response.
