OBJECTIVE The purpose of this study was to investigate the root/number of roots and morphology of mandibular premolars and molars in a Korean population, and to evaluate the prevalence of three-rooted mandibular first molars having distolingual (DL) roots, three-rooted mandibular second molars, and C-shaped roots in mandibular second molars. METHODS(More)
There is increasing interest in the therapeutic potential of stem cells because stem cells are promising candidates for the regeneration of tissue and treatment of diseases. Increasing evidence supports, multipotent stem cells may be obtained postnatally in different organs and tissues including bone marrow, synovium, adipose tissue, muscle and dental pulp.(More)
Albuminuria and periodontitis are both commonly associated with systemic inflammation. However, the association between urinary albumin excretion (UAE) and periodontitis in patients with type 2 diabetes has not been fully investigated. This study aimed to investigate the association between UAE and periodontitis in Korean adults with type 2 diabetes.This(More)
Stem cells can be isolated postnatally in different tissues including bone marrow, adipose tissue, muscle, and periosteum. Research has been performed using stem cell combined with scaffold to regenerate bony defect. The aim of this study was (1) to establish the chronic bone defect model for studying bone regeneration in alveolar process of rabbit mandible(More)
PURPOSE There is a lack of sufficient data in comparison of optical coherence tomographic (OCT) findings between first- and second-generation drug-eluting stents (DES). Compared to first-generation (i.e., sirolimus- or paclitaxel-eluting stents), second-generation DESs (i.e., everolimus- or biolinx-based zotarolimus-eluting stents) might have more favorable(More)
BACKGROUND A prolonged PR interval is known to be a poor prognostic factor in cardiovascular disease. The aim of this study was to investigate the association between PR interval and clinical outcome in patients undergoing radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF). METHODS AND RESULTS We prospectively included 576 patients with(More)
Tacrolimus is a 23-membered macrolide lactone with potent immunosuppressive activity that is effective in the prophylaxis of organ rejection following kidney, heart and liver transplantation. Tacrolimus also exerts a variety of actions on bone metabolism. The aim of the present study was to evaluate the effects of different concentrations of tacrolimus on(More)
This study was performed to evaluate the effect of surface treatment of titanium, including: machined (MA), sand-blasted and acid-etched (SA), and hydroxyapatite-coated (HA) surfaces, and application of bone morphogenetic protein-2 (BMP-2) on attachment, proliferation, and differentiation of stem derived from buccal fat pad. Stem cells were isolated from(More)
PURPOSE Actinomycosis is an uncommon chronic granulomatous disease that presents as a slowly progressive, indolent, indurated infiltration with multiple abscesses, fistulas, and sinuses. The purpose of this article is to report on a case of actinomycosis with clinical findings similar to periodontitis. METHODS A 46-year-old female presented with recurrent(More)
An 80-year old woman suffered from sudden onset of chest pain and dyspnea, and visited the emergency room. She received stent implantation with a biolimus A9-eluting stent (Nobori® 3.0×24 mm) at a the mid-portion of the left anterior descending artery 5 months prior to admission. The emergency 5-month follow-up angiogram was performed under the impression(More)
