Purpose: This study was performed to investigate the incidence and configuration of bifid mandibular canal in a Korean population by using cone-beam computed tomography (CBCT) imaging.Materials Methods: CBCT images 1933 patients (884 male 1049 female) were evaluated PSR-9000N Alphard-Vega 3030 Dental CT units (Asahi Roentgen Ind. Co., Ltd, Kyoto, Japan).Image analysis OnDemand3D software (CyberMed Inc., Seoul, Korea).The identified classified into four types, namely, forward canal,...
Abstract Objectives The objective of this study is to evaluate the anatomical structures in maxillary sinus with relation lateral approach elevation utilizing cone beam computed tomography ( CT ) scans taken prior surgery. Materials and methods A total 150 images were acquired from patients (90 men 60 women; mean age, 49.4 years, range 23–86 years) who being treated implant‐supported restorations posterior edentulous maxilla. Of scans, 65 right 85 left sinus. Measurements conducted on...
Our objective was to examine whether adjunct teriparatide administration and local application of recombinant human bone morphogenetic protein-2 (rhBMP-2) is beneficial for the regeneration jaw in patients with medication-related osteonecrosis (MRONJ). This study enrolled 17 diagnosed MRONJ. All received sequestrectomy under general or anesthesia suspension bisphosphonate. The ratio compared on cone beam computed tomography (CBCT) scans, acquired immediately post-operation after 6 months....
Abstract Objectives The purpose of this study was to confirm volume stability biphasic calcium phosphate ( BCP ) through the changes grafted over time by 3 D CT analyzing software program. Patients and Methods Fifteen patients, 16 sinuses who were scheduled a staged implantation sinus floor elevation SFE )–lateral window technique from 2009 2011 included in study. Of 15 eight male seven female (mean age 50.1). For augmentation, with local blood packed loosely into maxillary site covered...
To validate the accuracy of a cone-beam computed tomography (CBCT)-guided surgical stent for orthodontic mini-implant (OMI) placement by quantitatively evaluating difference between CBCT-prescribed and actual position mini-implants in preoperative postoperative CBCT images.A was fabricated using Teflon-Perfluoroalkoxy, which has appropriate biological x-ray attenuation properties. Polyvinylsiloxane impression material used to secure custom-made onto swine mandibles. scanning done with place...
Although overexpression of the nuclear factor κB inhibitory and ubiquitin-editing enzyme A20 is thought to be involved in pathogenesis inflammatory diseases, its function periodontal disease remains unknown. The aims present study were evaluate expression patients with periodontitis effects overexpression, using a recombinant adenovirus encoding (Ad-A20), on response osteoclastic differentiation lipopolysaccharide (LPS)- nicotine-stimulated human ligament cells (hPDLCs).The concentration...
The positions of the mandibular foramen (MnF) and lingula affect success rate inferior alveolar nerve block. objective this study was to investigate aspects MnF relevant for block anesthesia using cone-beam computed tomography (CBCT).Fifty CBCT scans were collected from a picture archiving communications system. All taken an Alphard Vega 3030 (Asahi Roentgen Co. Ltd., Kyoto, Japan). Fifty-eight MnFs 30 subjects included in study. position MnF, size lingula, shape measured recorded. data...
This study aimed to establish updated diagnostic reference levels (DRLs) for dental imaging modalities in South Korea. In cooperation with the Korea Disease Control and Prevention Agency, various types of institutions (dental clinics, hospitals university hospitals) were selected investigate status radiation equipment use. Subsequently, over 300 units randomly each device type (intraoral, panoramic cone-beam computed tomography [CBCT]) as measurement samples. DRLs defined 75th percentile...
Sublingual traumatic ulceration is rare and a benign, ulcerative granulomatous process that occurs as result of repetitive trauma the oral mucosal surfaces by teeth. Treatment should begin conservatively focus on eliminating source trauma. In our cases, we chose conservative treatment grinding teeth placing composite resin over offending applied orabase. At follow-up, confirmed lesion was resolved infant feeding normally.
Malignant transformation of fibrous dysplasia (FD), which was first introduced by Coley and Steward1 is very rare. We present a case malignant monostotic mandibular FD after 2 surgical excisions, 20 15 years ago, respectively. The treatment choice usually conservative. With the advanced techniques, radical excisions followed immediate reconstruction have been reported. However, decision criteria are still controversial we might think that good method for recurrent lesions based on recent...
Neuropathic pain is a complex state showing increased response with dysfunctional inhibitory neurotransmission. The TREK family, one of the two pore domain K⁺ (K2P) channel subgroups were focused among various mechanisms neuropathic pain. These channels influence neuronal excitability and are thought to be related in mechano/thermosensation. However, only little known about expression role TREK-1 TREK-2, It performed know whether and/ or 2 positively dorsal root ganglion (DRG) mouse model,...
Two-pore domain K(+) (K(2P)) channels that help set the resting membrane potential of excitable and nonexcitable cells are expressed in many kinds tissues. However, expression K(2P) has not yet been reported bovine germ cells. In this study, we demonstrate for first time reproductive organs Korean cattle. RT-PCR data showed members channel family, specifically KCNK3, KCNK9, KCNK2, KCNK10, KCNK4, were ovary, testis, oocytes, embryo, sperm. Out these channels, KCNK2 KCNK4 mRNAs abundantly...
A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward among elite Korean Taewondo athletes.Survey questionnaires were given 152 athletes participating in Korea National Taekwondo team selection event for 2010 Guangzhou Asian Games. Questionnaires consisted three sections, reasons not wearing last section test acceptance on current when identified problems resolved. For analyzing difference response, χ(2) used significant (α) set up...
Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare carcinoma, which arises within the jaws without connection to oral mucosa and presumably develops from remnant of odontogenic epithelium.We present case solid type PIOSCC in 52-year-old male patient complaining dull pain on his left lower molar.In this case, early stage mimicking periapical lesion might lead one-year delay treatment due misdiagnosis osteomyelitis after extraction third molar.The clinical, radiological,...
This study was performed to investigate the influence of object shape and distance from center image on volumetric accuracy cone-beam computed tomography (CBCT) scans, according different parameters tube voltage current.Four geometric objects (cylinder, cube, pyramid, hexagon) with predefined dimensions were fabricated. The consisted Teflon-perfluoroalkoxy embedded in a hydrocolloid matrix (Dupli-Coe-Loid TM; GC America Inc., Alsip, IL, USA), encased an acrylic resin cylinder assembly. An...
Bisphosphonates (BPs) used for treating skeletal diseases can induce bisphosphonate-related osteonecrosis of the jaw (BRONJ). Despite much effort, effective remedies are yet to be established. In present study, we investigated feasibility polydeoxyribonucleotide (PDRN) extracted from salmon sperm treatment BRONJ, in a BRONJ-induced rat model. Compared with samples, PDRN-treated samples exhibited lower necrotic bone percentages and increased numbers blood vessels attached osteoclast...
Abstract Introduction This study aimed to validate a three‐dimensional (3D) printed model provide training for supernumerary teeth (SNTs) extraction. Materials and Methods Each of the 30 participants, grouped as experienced without experience, conducted two identically simulated surgeries on 3D‐printed replica human mixed dentition with SNT. The surgery time, area bony window volume removed material were measured; subsequently, responses five‐item questionnaire recorded. collected data...
