Bone Morphogenetic Proteins And Periodontal Repair, Michael B. Lee

Loma Linda University Electronic Theses, Dissertations & Projects

For over thirty years now, research has been carried out to isolate and purify bone morphogenetic protein (BMP), a substance which has been shown to induce heterotopic bone formation in various animal species. Recent advances in the fields of developmental biology, molecular biology and genetics, have shown that the BMPs not only are responsible for postfetal bone induction (including normal bone remodeling, healing and repair), but are also critical during embryogenesis - not only in regards to the skeletal system, but quite possibly in the morphogenesis and pattern formation of other tissues and organs as well.

Due to their bone …

Periodontal Repair In Dogs : Effect Of Recombinant Human Transforming Growth Factor Beta-1 On Guided Tissue Regeneration, Saghi Shayan Razi

Loma Linda University Electronic Theses, Dissertations & Projects

The objective of this study was to evaluate bone and cementum regeneration in the critical size, supraalveolar, periodontal defect model following surgical implantation of recombinant human transforming growth factor beta-1 (rhTGFß-1) in conjunction with guided tissue regeneration (GTR). Five male beagle dogs were used in a split-mouth design. Alternate jaw quadrants in consecutive animals received GTR with rhTGFß-1 in a resorbable calcium carbonate carrier. Contralateral jaw quadrants received GTR with carrier only (control). The healing interval was 4 weeks. Clinical healing was generally uneventful, however, minor membrane exposures were observed for both treatments with limited gingival inflammation. All defects with …
