Periodontitis is a widespread chronic inflammatory disease caused by interactions between periodontal bacteria and homeostasis in the host. We aimed to investigate performance reliability of machine learning models predicting severity periodontitis. Mouthwash samples from 692 subjects (144 healthy controls 548 generalized periodontitis patients) were collected, genomic DNA was isolated, copy numbers nine pathogens measured using multiplex qPCR. The are as follows: Porphyromonas gingivalis...
Abstract Background Type 2 diabetes mellitus (DM) is a complex metabolic disorder that causes various complications, including periodontitis (PD). Although bidirectional relationship has been reported between DM and PD, their immunological remains poorly understood. Therefore, this study aimed to compare the immune response in patients with PD alone those both (PDDM) expand our knowledge of complicated connection DM. Methods Peripheral blood mononuclear cells were collected from 11 healthy...

All examinations before treatment, 1 month after 3 months treatment.There no significant differences between test group control group. Microbiological analysis revealed that...
The aim of this study was to evaluate the ability Porphyromonas gingivalis (P. gingivalis) induce oxidation high-density lipoprotein (HDL) and determine whether oxidized HDL induced by P. exhibited altered antiatherogenic function or became proatherogenic.P. THP-1 monocytes were cultured, extent evaluated a thiobarbituric acid-reactive substances (TBARS) assay. To proatherogenic properties gingivalis-treated HDL, lipid quantified TBARS assay, tumor necrosis factor alpha (TNF-α) levels...
Abstract Type 2 diabetes mellitus (T2DM) and periodontitis (PD) have intricated connections as chronic inflammatory diseases. While the immune response is a key factor that accounts for their association, underlying mechanisms remain unclear. To gain deeper understanding of connection, we conducted research using multiomics approach. We generated whole genome methylation profiling array data from periodontium PD patients with DM (PDDM) without to confirm genetic epigenetic changes....
Purpose: Few studies have examined periodontal pathogens from saliva samples in periodontally healthy young adults.The purposes of this study were to determine the prevalence periodontopathic bacteria and quantify using real-time polymerase chain reaction (PCR) assays Korean adults under 35 years age.Methods: Nine major analyzed by PCR 94 adults.Quantification Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Prevotella intermedia,...
Cathepsin K (CTSK) is a cysteine protease that mainly produced from mature osteoclasts and contributes to the destruction of connective tissues mineralized matrix as consequence periodontal disease (PD). However, few studies have reported its regulatory role in osteoclastogenesis-supporting cells inflammatory conditions. Here, we investigated CTSK cells, focusing on modulation paracrine function. Microarray data showed was upregulated PD patients compared with healthy individuals, which...
This study aimed to profile differentially expressed (DE) exosomal RNAs in healthy subjects and periodontitis patients compare their levels before after treatment.Plasma samples from with (pre-/post-periodontal treatment) were collected for this case-control study. After isolation of exosomes the plasma, RNA was extracted small sequencing performed (3 samples, 4 pre-treatment 5 post-treatment samples). Two-way analyses conducted according treatment status group, unpaired analysis (grouping...
A strong correlation between chronic periodontitis and systemic diseases (e.g., cardiovascular disease, metabolic disorders) has been suggested for several decades. However, the evidence supporting this is restricted primarily to epidemiologic studies, with only a few experimental outcomes confirming such providing information about underlying molecular mechanisms. To reveal as well relevant pathway, we investigated effects of Porphyromonas gingivalis Fusobacterium nucleatum, which play...
Abstract Background Periodontitis is a major inflammatory disease of the oral mucosa that not limited to cavity but also has systemic consequences. Although importance chronic periodontitis been emphasized, immune response induced by and its therapeutic effects remain elusive. Here, we report transcriptomes peripheral blood mononuclear cells (PBMCs) from patients with periodontitis. Methods Using single-cell RNA sequencing, profiled PBMCs healthy controls paired pre- post-treatment We...
Periodontitis is an infectious disease that associated with microorganisms colonize the tooth surface. Clinically, periodontal condition stability reflects dynamic equilibrium between bacterial challenge and host response. Therefore, pathogen assessment can assist in early detection of periodontitis. Here we developed a grading system called index (PPI) by analyzing copy numbers multiple pathogens both healthy chronic periodontitis patients. We collected 170 mouthwash samples (64...
This study aimed to apply fluoride formulations enamel with cold atmospheric plasma (CAP) and analyze the uptake, retention, acid resistance quantitatively. Human specimens were divided randomly into 2 groups: group APF1, 1.23% acidulated phosphate (APF) gel; APF2, APF gel CAP. Fluoride CAP applied samples 4 times at 1-wk intervals. The also stored in artificial saliva for wk evaluate retention of fluoride. content on fluoride-treated was measured by an electron probe microanalyzer. To...

The keys to successful esthetic implant therapy in the anterior region are natural-looking restorations and an adequate alveolar ridge volume. Destruction of periodontal tissue resulting from and/or endodontic inflammation causes problems. Forced eruption is a valuable adjunct augmenting soft hard where insufficient for esthetics. In this article, forced was adopted site development prior placement augmented vertically using technique. This technique simplified surgical procedure without...
Periodontitis is an inflammatory disease caused by Porphyromonas gingivalis (P. gingivalis) in the oral cavity. This periodontal causes damage to ligament and alveolar bone can cause tooth loss, but there no definite treatment yet.
