Oral health problems such as periodontal disease, dental caries, and tooth loss have been suggested to associations with cardiovascular disease. This study aimed evaluate whether oral hygiene behaviour can alleviate risk associated status using a nationwide population-based cohort.The data of 247 696 healthy adults aged 40 years or older who underwent an screening programme had no history major events were extracted from the National Health Insurance System-National Screening Cohort. After...
Insufficient bone volume is one of the major challenges encountered by dentists after dental implant placement. This study aimed to evaluate efficacy a customized three-dimensional polycaprolactone (3D PCL) scaffold fabricated with 3D bio-printing system facilitate rapid alveolar regeneration. Saddle-type defects were surgically created on healed site extracting premolars from mandibles four beagle dogs. The radiologically examined using computed tomography for designing PCL block fit defect...
In this study, we designed scaffolds coated with gold nanoparticles (GNPs) grown on a polydopamine (PDA) coating of three-dimensional (3D) printed polycaprolactone (PCL) scaffold.
Abstract Background Previous studies have suggested that frequent toothbrushing is associated with a lower risk of future cardiovascular events. We sought to investigate further the relationship between toothbrushing, factors, and lifestyle behaviours. Methods analysed cross-sectional survey including 13,761 adults aged 30 years or older without history diseases from Korean National Health Nutritional Examination Survey. Conventional factors (blood pressure, lipid profiles, fasting glucose),...
Root resection is one treatment option for preserving molars with furcation involvement. This study evaluated the prognosis of root-resection therapy retrospectively and examined factors influencing survival rate resected molars.Root-resection was performed on 691 in 579 patients. The associated were from 342 402 that had been followed up >1 year. Survival analysis used to statistically analyze factors.Over past 10 years, 102 cases (29.8%) failed. classified into four groups analyzed...
Peri-implantitis is a chronic inflammatory process with advanced bone loss and impaired healing potential. For peri-implantitis treatment, tissue engineering can be applied to enhance regeneration of peri-implant defects. This study aimed evaluate ex vivo morphogenetic protein 2 (BMP2) gene delivery using canine periodontal ligament stem cells (PDLSCs) for Canine PDLSCs were transduced adenoviral vectors containing BMP2 (BMP2/PDLSCs). After was induced by ligature placement in six beagle...
Bone tissue healing is a dynamic, orchestrated process that relies on multiple growth factors and cell types. Platelet-derived factor-BB (PDGF-BB) released from platelets at wound sites induces cellular migration proliferation necessary for bone regeneration in the early process. morphogenetic protein-2 (BMP-2), most potent osteogenic differentiation inducer, directs new formation of defects. This study evaluated combinatorial treatment protocol PDGF-BB BMP-2 critical-sized defect model. To...
Purpose: Chronic periodontitis is an inflammatory disease induced by pathogenic bacterial accumulation.A novel index, the periodontal inflamed surface area (PISA), represents sum of pocket depth bleeding on probing (BOP)-positive sites.It advantageous for data processing and analysis because it can be treated as a continuous variable to quantify inflammation.In present study, we evaluated correlations between PISA classifications, examined index integrating discrete conventional...
Recombinant human bone morphogenetic protein 2 (rhBMP-2) has been widely used in tissue engineering to enhance regeneration because of its osteogenic inductivity. However, clinical outcomes can vary depending on the scaffold materials deliver rhBMP-2. In this study, 3D-printed scaffolds with a ratio 1:1 polycaprolactone and beta-tricalcium phosphate (PCL/T50) were applied as carriers for rhBMP-2 mandibular defect models dog models. Before vivo application, vitro experiments conducted....
Purpose: Micro-computed tomography (micro-CT) has been widely used in the evaluation of regenerated bone tissue but reliability micro-CT not yet established.This study evaluated correlation between histomorphometric analysis and performing new formation measurement.Methods: Critical-size calvarial defects were created using a 8 mm trephine bur total 24 Sprague-Dawley rats, collagen gel mixed with autogenous rat marrow stromal cells (BMSCs) or BMSCs transduced by adenovirus containing...
Posterior maxillary region is considered to be the most challenging area for dental implant placement. Lateral window opening gold standard procedure sinus augmentation in this area. The purpose of study evaluate lateral wall thickness using computed tomography (CT) edentulous patients. Computed images 302 patients were analysed. Using floor as reference point regions, was measured on CT scans. After drawing a tangent line at lowest floor, another perpendicular drawn same floor. Thickness...
Abstract As a case study, the fate of pollutants subjected to long‐range transport over northeast Asia was investigated. These originated as emitted particulate from Chinese source area, moved across Yellow Sea (YS), and entered Korean Peninsula (KP) during Megacity Air Pollution Studies Seoul (MAPS‐Seoul) 2015 aircraft field campaign. The MAPS‐Seoul campaign, designed precampaign Korea‐United States Quality (KORUS‐AQ) performed diagnose air quality around KP YS. Of particular interest...
Purpose: Direct application of atmospheric-pressure plasma jets (APPJs) has been established as an effective method microbial decontamination.This study aimed to investigate the bactericidal effect direct APPJ using helium gas (He-APPJ) on Porphyromonas gingivalis biofilms sandblasted and acid-etched (SLA) titanium discs.Methods: On SLA discs covered by P. biofilms, with (He) a discharge was applied at 3 different time intervals (0, 3, 5 minutes).To evaluate itself, He gas-only group used...
Purpose: Oral lichen planus (OLP) is a chronic oral mucosal disease that has been recognized as an immune condition.The purpose of this study was to evaluate factors affecting the clinical outcomes topical corticosteroid application on OLP lesions using dexamethasone gargle and ointment.Methods: The charts patients who were clinically diagnosed with treated from July 2003 August 2017 at Section Dentistry Seoul National University Bundang Hospital thoroughly evaluated identify subjects...
This study evaluated decontamination methods using a dental water jet and floss on microthreaded implants for regenerative periimplantitis therapy.In 6 beagle dogs, experimental was induced, procedures, including manual saline irrigation (control group), (group 1) with flossing 2), were performed. After in situ some of the implant fixtures (n = 4 per group) retrieved analysis by SEM, whereas other underwent therapy. 3 months healing, animals killed.The SEM examination indicated that surfaces...
