Peri-implant tissue response following connective tissue and bone grafting in conjunction with immediate single-tooth replacement in the esthetic zone: a case series.

Purpose: This case series evaluated the peri-implant tissue response following extraction and immediate placement and restoration of an implant in conjunction with subepithelial connective tissue grafting (SCTG) and bone grafting in the esthetic zone. Implant success rates and the peri-implant tissue response were also reported.

Methods And Materials: Ten patients (four men, six women) with a mean age of 48 years (range, 35 to 70) underwent extraction and immediate tooth replacement with SCTG and were evaluated clinically and radiographically presurgically (T0), immediately after immediate tooth replacement and SCTG (T1), and at 3 months (T2), 6 months (T3), and 12 months (T4) after surgery.

Prognostic value of LYVE-1-positive lymphatic vessel in tongue squamous cell carcinomas.

The density of lymphatic vessels in 52 cases of human tongue squamous cell carcinoma (TSCC) and normal portions was analyzed. TSCC specimens were immunostained with antibodies against lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1) and podoplanin monoclonal antibody (D2-40). The significance of the LYVE-1-positive vessel density (LVD) was calculated in 6 topographic areas and investigated on the basis of specific clinical and histo-pathological parameters.

Detection of fascin and CCR-7 positive mature dendritic cells in oral lichen planus.

Background: Dendritic cells (DC) play a crucial role in the pathogenesis of oral lichen planus (OLP) with respect to antigens presented to T cells. We performed immunohistochemical analysis to elucidate the process of activation of DC in OLP.

Methods: Thirty biopsy specimens were obtained from the patients with OLP.
