Eleven intrabony periodontal lesions in five volunteer patients received surgical debridement followed by site implantation of a porous particulate polymeric composite (HTR polymer). These patients were observed over time periods varying from 4 weeks to 26 weeks. At the end of the individual observation periods, treated sites were surgically removed in block for histologic analysis. Clinical ob...

We compared the clinical efficacy of orally administered valdecoxib and piroxicam for the prevention of pain, trismus and swelling after removal of horizontally and totally intrabony impacted lower third molars. Twenty-five patients were scheduled to undergo removal of symmetrically positioned lower third molars in two separate appointments. Valdecoxib (40 mg) or piroxicam (20 mg) was administe...

For some authors trabecular bone is highly visible in intraoral radiographs. For other authors, the observed intrabony trabecular pattern is a representation of only the endosteal surface of cortical bone, not of intermedullary striae. The purpose of this preliminary study was to investigate the true anatomical structures that are visible in routine dental radiographs and classically denoted tr...

PURPOSE THE PURPOSE OF THIS STUDY WAS TO ASSESS AND COMPARE THE CLINICAL AND RADIOGRAPHIC OUTCOMES OF GUIDED TISSUE REGENERATION THERAPY FOR HUMAN PERIODONTAL INTRABONY DEFECTS USING TWO DIFFERENT COLLAGEN MEMBRANES: a porous nonchemical cross-linking collagen membrane (NC) and a bilayer collagen membrane (BC). METHODS Thirty subjects were randomly assigned and divided into the following 3 gr...

Amebloblastoma as the most common epithelial odontogenic neoplasm may occur in two forms of central and peripheral. This report presents a case of a 41-year-old Iranian female with a six-month complaint from a painless mass in the right posterior portion of the mandible. The case was diagnosed as an exophytic epulis-like peripheral component with characteristics of peripheral ameloblastoma and ...

Context: This article reviews the available evidence about the barrier membranes utilized in Guided Tissue Regeneration process to prevent the migration of unfavorable cells to the wound area. Evidence Acquisition: Available evidence about membranes properties and their different uses were reviewed, and the results of clinical and animal studies and systematic reviews were gathered. Results: A ...

In the last decades, Guide Tissue Regeneration (GTR) technique has been applied for the treatment of various periodontal defects such as intrabony defects, furcation involvements and localized gingival recession defects. From early days of using membranes with the simple aim of minimizing toxic response in the host, membranes have come a long way. Third generation membranes not only act as barr...

Numerous animal and human studies have provided evidence supporting the belief that periodontal ligament stem cells (PDLSCs) can be harnessed for regeneration of periodontal tissues. Based on current literature on the use of ex vivo stem culture and associated problems, this case report describes a novel approach of direct application PDLSCs using stem cell assistance in periodontal regeneratio...

statement of problem: recent literatures show that accelerated portland cement (apc) and calcium hydroxide ca (oh) 2 may have the potential to promote the bone regeneration. however, certain clinical studies reveal consistency of ca (oh) 2, as one of the practical drawbacks of the material when used alone. to overcome such inconvenience, the combination of the ca (oh) 2 with a bone replacement ...
