Abstract

In Part I, a computer imaging technique was used to measure the volumetric fill that occurred in surgically created grade II molar furcation defects after they had been treated using the principles of guided tissue regeneration. In Part II, the volumetric fill for each of the specific tissues comprising the defect fill (epithelium, connective tissue, bone, and cementum) was compared. The histologic material consisted of defects treated using one of three types of surgical treatment as well as untreated control sites. All volumetric measurements were expressed as a percentage of the original surgically created defect size, with 100% indicating complete healing of the defect. The results indicate that none of the defects achieved complete healing. Teeth receiving flap debridement had the most overall defect fill (79.50% comprised of 17.13% bone, 35.81% connective tissue, 37.35% epithelium, and 9.71% cementum). Teeth that received a biodegradable barrier showed a mean overall defect fill of 74.98% (7.41% bone, 47.13% connective tissue, 36.20% epithelium, and 9.26% cementum. Sites treated with an exclusion barrier showed 70.75% overall fill (9.63% bone, 40.89% connective tissue, 39.00% epithelium, and 10.48% cementum). The untreate...Continue Reading

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.
