Abstract Aim This study aimed to investigate the association between work patterns and periodontal disease. Materials methods Data were collected from Korea National Health Nutrition Examination Survey 2007 2012, data 22,508 subjects aged ≥19 years included. An individual's pattern was classified as either daytime or shift work. Sleep duration categorized into three ranges: ≤5, 6–8, ≥9 h/day. A multivariate logistic regression model used determine adjusted odds ratio (OR) for CPI (Community...
Recent several reports have demonstrated that periodontitis is prevalent and adversely affects the survival in patients with chronic kidney disease (CKD) or end-stage disease. However, its impact on transplant outcomes remains uncertain.This retrospective cohort study included 136 167 patients, respectively, who underwent living donor transplantation (KT) at Seoul National University Hospital from July 2012 to August 2016 Korea April 2008 October 2018. We divided into three groups according...
The significance of keratinized tissue for peri-implant health has been emphasized. However, there is an absence clinical evidence the use a xenogeneic collagen matrix (XCM) to manage mucositis and peri-implantitis. Therefore, purpose this study was investigate outcomes after augmentation using XCM management diseases.Twelve implants (5 with 7 peri-implantitis) in 10 patients were included study. Non-surgical treatments first performed, but inflammation persisted all implant sites. sites...
Abstract It is well known that periodontitis, diagnosed mainly by periodontal probing, associated with adverse pregnancy outcomes. However, probing time-consuming, highly discomforting, inaccurate, and invasive. We aimed to assess whether periodontitis severity based on radiological staging in accordance the 2017 new consensus classification was related neonatal The medical records of 165 mothers who underwent panoramic radiography within 5 years before after time delivery their singleton...
We present simple p–i–n structures with single-emitting and mixed emitting layers for highly efficient phosphorescent blue organic devices. Using a high-triplet-energy-hole-transporting material of 1,1-bis(4-methylphenyl)-aminophenyl-cyclohexane (TAPC) high-triplet-energy-electron-transporting 1,3,5-tris( m -pyrid-3-ylphenyl)benzene (Tm 3 PyPB), the structure has been realized by doping MoO as p-dopant Cs 2 CO an n-dopant. A very low onset voltage 3.0 V driving 4.0 to obtain brightness 1000...
We present excellent polymeric buffer materials based on the poly(9,9-dioctylfluorene-co-N, N-di(phenyl)-N,N-di(3-carboethoxyphenyl)benzidine) (BFE) for highly efficient solution processed organic light emitting diodes (OLEDs). Doped BFE with 3,5-dinitrobenzonitrile (35DNBN), a strong electron acceptor results in significant improvement of current flow and driving voltage. Maximum current- power-efficiency value 7.2 cd/A 5.5 lm/W are demonstrated from blue OLEDs these doped anode system. The...
The aim of this study was to measure the convexity lateral wall maxillary (Mx) sinus and identify locational distribution antral septa in relation zygomaticomaxillary buttress (ZMB), order suggest another anatomical consideration surgical modification floor elevation procedures. This designed as a cross-sectional study, total 134 patients 161 sinuses containing edentulous alveolar ridges were analyzed. angle between anterior walls Mx (lateral [LSA]), midpalatal line (anterior [ASA])...
The method for prediction of an ideal doping concentration in phosphorescent organic light emitting devices (PHOLEDs) is proposed by consideration filling imaginary spherical molecules 4×4×4 face-centered cubic lattice. Calculated about 0.93 mol % similar size host and guest molecules. Two different materials are selected to demonstrate this concept. 4,4'-N,N '-dicarbazolebiphenyl (CBP) with fac-tris(2-phenyl-pyridinato)iridium(III) [Ir(ppy)3] system predicted be 1.19 wt (0.93 %), which...
Nitrogen-containing bisphosphonates lead to the depletion of geranylgeranyl pyrophosphate involved in mevalonate pathway. The effect geranylgeraniol (GGOH) on human osteoblast and osteoclast activities suppressed by zoledronate was investigated this study. GGOH osteoblasts osteoclasts subjected treatment with analyzed assessing cell viability, differentiation, resorption ability, gene expression, protein synthesis. Cell viability osteoprogenitor cells restored GGOH. Osteoclast...
The present study aimed to report (1) the sequela of sinus floor elevation (SFE) in posterior maxilla with severe membrane thickening and an undiagnosed fungal colonization but a patent ostium (2) treatment course without implant removal. A 73-year-old woman underwent dental placement left maxillary area. Although patient was asymptomatic, Haller cells observed on radiographic examination, patent. After SFE simultaneous placement, developed acute sinusitis referred otolaryngologist....
It is generally recommended that severe sinus membrane (SM) thickening should be treated prior to maxillary augmentation (MSA), but during lateral MSA, inflammatory tissue/product may removed by puncturing the SM. The present case report demonstrates surgical experience of MSA with simultaneous removal for sinuses opacification. In three patients requiring dental implant placement in posterior maxilla, SM was observed, they were asymptomatic. gently elevated, followed SM, removing tissue via...
This study aimed to investigate the effects of shift work on periodontal disease in blue-and white-collar workers and examine interaction between occupation patterns. Data were collected from Korea National Health Nutrition Examination Survey conducted by Korean Ministry Welfare for a total nine years 2007 2015. Participants with missing outcome variables excluded analysis 32,336 participants included final analysis. Univariable odds ratios (OR) calculated using logistic regression model 95%...
Abstract Background This study aimed to demonstrate the efficacy of erbium, chromium-doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser-assisted nonsurgical periodontal therapy in periodontitis patients during 8 weeks healing. Methods A split-mouth, single-blinded, randomized controlled clinical trial was conducted on 12 diagnosed with stage III/IV had a minimum two teeth probing pocket depth (PPD) > 5 mm at least quadrants. Upon randomization, each quadrant assigned for...
Periodontitis is a potential risk factor for preterm birth (PTB) in women; however, the causal relationship or exact mechanism remain unknown. This study aimed to compare oral microbiome features of mothers with full-term (FTB) those who had delivery.
