In patients with human epidermal growth factor receptor-2 (HER2)-overexpressing breast cancer, treatment trastuzumab has been shown to markedly improve the outcome. We investigated role of on brain metastasis (BM) in HER2-positive cancer patients. From 1999 2006, 251 were treated palliative chemotherapy for metastatic at Samsung Medical Center. The medical records these analysed study effects BM prevalence and outcomes. Patients grouped according therapy: pre-T (no therapy) vs post-T...
Abstract This study aimed to evaluate the accuracy of automated deep learning (DL) algorithm for identifying and classifying various types dental implant systems (DIS) using a large-scale multicenter dataset. Dental radiographs pos-implant surgery were collected from five college hospitals 10 private clinics, validated by National Information Society Agency Korean Academy Oral Maxillofacial Implantology. The dataset contained total 156,965 panoramic periapical radiographic images comprised...
This study aimed to evaluate the efficacy of deep learning (DL) for identification and classification various types dental implant systems (DISs) using a large-scale multicenter data set. We also compared accuracy DL professionals. The set, which was collected from 5 college hospitals 10 private clinics, contained 37,442 (24.8%) periapical 113,291 (75.2%) panoramic radiographic images consisted total manufacturers 25 different DISs. evaluated pretrained modified ResNet-50 architecture,...
The aim of this study was to identify variables that can be used for osteoporosis detection using strut analysis, fractal dimension (FD) and the gray level co-occurrence matrix (GLCM) multiple regions interest develop an model based on panoramic radiography.A total 454 radiographs from oral examinations in our dental hospital 2012 2015 were randomly selected, equally distributed among osteoporotic non-osteoporotic patients (n = 227 each group). classified by bone mineral density (T-score)....
Abstract Regeneration of peripheral nerve injury remains a major clinical challenge. Recently, mesenchymal stem cells (MSCs) have been considered as potential candidates for regeneration; however, the underlying mechanisms remain elusive. Here, we show that human gingiva-derived MSCs (GMSCs) could be directly induced into multipotent NPCs (iNPCs) under minimally manipulated conditions without introduction exogenous genes. Using crush-injury model rat sciatic nerve, demonstrate GMSCs...
Abstract Background Medication-related osteonecrosis of the jaw (MRONJ) can cause significant pain and loss aesthetics function if not treated properly. However, diagnosis still relies on detailed intraoral examinations imaging. Prognosis varies even among patients with similar stages or conditions MRONJ, emphasizing need for a deeper understanding its complex mechanisms. Thus, this study aimed to identify oral microbiota MRONJ. Methods This single-center prospective cohort included...
The risk of locoregional recurrence in resected gastric adenocarcinoma is high, but the benefit adjuvant treatment remains controversial. In particular, after extended lymph node dissection, role radiotherapy questionable. Since 1995, we started a clinical protocol chemoradiotherapy D2 gastrectomy and analysed patterns failure for 291 patients. Adjuvant chemotherapy consisted five cycles fluorouracil leucovorin, concurrent was given with 4500 cGy from second cycle chemotherapy. With median...
Seo D‐G, Gu Y, Yi Y‐A, Lee S‐J, Jeong J‐S, Chang S‐W, J‐K, Park W, Kim K‐D, Kum K‐Y. A biometric study of C‐shaped root canal systems in mandibular second molars using cone‐beam computed tomography. International Endodontic Journal , 45 807–814, 2012. Abstract Aim To investigate the configuration canals molars, wall thickness and orientation thinnest area at 1‐mm intervals from orifice to apex by tomographic (CBCT) images. Methodology Three‐dimensional CBCT images 92 Korean having were...
The aim was to analyze the prevalence rate of proximal contact loss (PCL) between implant-fixed prostheses (IFPs) and adjacent teeth investigate associated factors.One hundred fifty participants were recruited for this prospective study from January 2009 December 2014. Two thirty-four IFPs supported by 384 implants posterior region followed up until June 2016. tightness had been recorded using aluminum strips different thicknesses with a regular interval after delivery. Proximal considered...
Dental clinics are exposed to various uncomfortable noises. The aim of this study was quantify the effectiveness active noise control devices in dental treatment conditions. Two types commercial headsets (Airpods Pro, QC30) and two (Alltalk, Quieton Dental) were used for experiment. Three sounds (high-speed handpiece, low-speed suction system) measured at three different distances from teeth model, typodont. 10, 40, 70 cm reflected positions patient, assistant, practitioner’s ears,...
ABSTRACT Introduction This study aimed to determine possible histological and radiological differences in alveolar ridge preservation (ARP), using moldable bone versus particulate bone. Methods After tooth extraction, 39 patients (40 teeth) were randomized (1:1) receive ARP materials (SBX group) or (PBX group). An absorbable collagen membrane was placed over the graft material surgical site sutured. Cone‐beam computed tomography taken immediately 5 months after ARP. Bone core samples from...
Abstract Background This study aimed to explore the effects of teriparatide (TPTD) on treatment duration, surgical procedures, and bone turnover markers in medication-related osteonecrosis jaw (MRONJ). Methods We analyzed 76 patients with MRONJ post-treatment divided them into conservative/surgical TPTD/non-TPTD groups. Key assessments included surgery count, changes (serum C-terminal telopeptide type 1 collagen [CTX], osteocalcin [OC], procollagen N-terminal propeptide [P1NP], parathyroid...
This randomized controlled trial aimed to educate patients and manage oral hygiene remotely via a smart toothbrush (ST) by using mobile applications improve habits evaluating the plaque state images from Q-ray cam, which is quantitative light-induced fluorescence (QLF) digital imaging device. In total, 68 children (aged 6–12 years) were randomly divided into three groups. Group I was assigned an electro-toothbrush (ET), group II (ST), III used manual (MT). Each checked after 1 3 months. Oral...
This study aimed to assess the effectiveness of an interactive education approach in oral and maxillofacial radiology for dentists, utilizing online educational program Mentimeter. Seven continuing sessions dentists were conducted employing Following these sessions, surveys gauged participants' responses learning method its effectiveness. The questionnaire comprised 20 questions categorized into convenience, active learning, academic achievement, time management, lecture quality. Among about...
Background: In patients with early-stage breast cancer, 5 years of treatment the selective estrogen receptor modulator (SERM) tamoxifen reduces cancer recurrence and mortality, whereas more than does not further reduce doubles risk endometrial cancer. We evaluated effects on tumor growth raloxifene, another SERM, after in mouse models cancers. Methods: Athymic, ovariectomized mice were bitransplanted tumors derived from human cells that either tamoxifen-naive or had been exposed to for short...
