PURPOSE The aim of this study was to evaluate the capability of a configured titanium mesh (CTM) to serve as a mechanical and biologic device for restoring a vertically defected/resorbed alveolar ridge. MATERIALS AND METHODS The study comprised 10 severely resorbed sites in 10 patients. Pre- and post-operative ridge measurements were taken with reference(More)
The hypothesis of the present study was that immediate loading of implant-supported restorations replacing single missing teeth could be a successful procedure. The present study compared the clinical success of immediately loaded single-tooth implants placed in fresh extraction sites to that of immediately loaded single-tooth implants placed in healed(More)
Collagenolytic activity in human carious and non-carious dentine matrix was compared. Results confirmed the presence of latent collagenase in demineralized dentine and indicated a slow rate of degradation of collagen substrate. Collagenolytic activity was enhanced with the addition of trypsin-TPCK to the demineralized dentine. More activity was observed in(More)
We examined cancer-associated fibroblasts (CAFs) and a panel of immunohistochemical markers of epithelial-mesenchymal transition (EMT) in 19 pair-matched oral tongue squamous cell carcinoma (SCC) and metastatic tumors to regional lymph nodes (RLNs). alpha-Smooth muscle actin (alpha-SMA) was studied to identify CAFs. EMT was studied with syndecan-1,(More)
BACKGROUND Nodular fasciitis (NF), a soft tissue lesion mainly composed of myofibroblastic cells, is well documented in various body locations however, in the oral cavity it is rare. The NF has non-specific histologic characteristics that might result in misdiagnosis and mistreatment. The aim of the study was to analyze clinico-pathologic correlations of NF(More)
Liposarcoma (LS), one of the most common malignant tumors, is considered as a rarity in the oral cavity, the tongue being the most frequent site for its occurrence. The purpose of the present study was to review and analyze the clinico-pathologic correlations of 32 cases of LS of the tongue, including four new cases from the files of our department. A total(More)
Nodular fasciitis of the oral mucosa is a rare lesion. The present article describes an additional case and discusses the difficulties in the histologic diagnosis. The final diagnosis is based on immunohistochemistry and electron microscopic morphology. Nodular fasciitis should be considered in the differential diagnosis of swellings in the oral mucosa.
Salivary gland neoplasms - pleomorphic adenoma, polymorphous low-grade adenocarcinoma, and adenoid cystic carcinoma - share a common histogenetic trait, but differ markedly in their biological properties. The objective of the study was to assess the polarization colors of picrosirius red-stained stromal collagen fibers in these salivary gland neoplasms to(More)
BACKGROUND Nonoperative management (NOM) of splenic injuries is a common practice in stable trauma patients. Nevertheless, age-related differences in the success rate of NOM have prompted inclusion of age among the criteria of patient selection. Elucidation of the cellular mechanism of splenic wound healing in the young versus that of adults may explain why(More)
Polarization colors of various purified collagens were studied in fibers of similar thickness. Three different soluble collagens of type I, insoluble collagen type I, lathyritic collagen type I, two p-N-collagens type I, pepsin extract collagen type II, two soluble collagens type III, p-N-collagen type III, and soluble collagen type V were submitted to a(More)
