Objectives: To examine mesiodens with regard to their status, influence on adjacent teeth and alteration during the follow-up period. Methods: From retrospective reviews of all patients who visited our institution from 1990–2001, we identified 200 (256 mesiodentes) were shown have mesiodentes basis a periapical radiograph, panoramic radiograph or an axial radiograph. Results: The number supernumerary was one in 146 cases (73%), two 52 (26%) three 2 (1%). Of 256 mesiodentes, direction crown...
The aim of this study was to investigate the characteristics implant sites on edentulous alveolar ridge in anterior maxilla. We studied bone quantity and quality at maxilla using CT images for 33 patients who underwent dental therapy our Department since 2006.Computed tomography (CT) (20 women: 13 men) encompassing were chosen examined. recipient placement determined based data an planning software (Simplant 11.0). mean density values Hounsfield unit (HU) recorded Simplant both simulated...
To evaluate the diagnostic value of MRI for odontogenic tumours.51 patients with tumours were subjected to pre-operative examinations. For liquid components, i.e. ameloblastomas and keratocystic (KCOTs), signal intensity (SI) uniformity their cystic components (UΣ) was calculated then UΣ values compared. solid that had been examined using dynamic contrast-enhanced (DCE-MRI), CImax (maximum contrast index), Tmax (the time when occurred), CIpeak (CImax × 0.90), Tpeak occurred) CI300 (i.e. CI...
To investigate the correlations among various temporomandibular joint (TMJ) findings on MRI and relationships between symptoms.425 patients (850 TMJs) with disorders (TMDs) who underwent were enrolled. Oblique sagittal proton density-weighted T2 weighted images in open- closed-mouth positions evaluated. included disc configuration, position, condylar morphology, bone marrow pattern, effusion. Symptoms TMJ pain, noise, limitation of mouth opening. For statistical analyses, Spearman's rank...
Total hip arthroplasty (THA), a critical surgery for joint pain relief and mobility restoration, involves careful consideration of various factors, including stem length. Short stems are often chosen their potential to reduce tissue damage thigh pain. Precise alignment is necessary alleviate complications such as loosening fractures. We aimed compare intramedullary insertion freedom changes between short standard in THA. This study based on preoperative planning simulations, highlighting the...
Background/Objectives: Mean kurtosis (MK) values in simple diffusion imaging (SDI)—a type of (DKI)—have been reported to be useful the diagnosis head and neck malignancies, for which pre-processing with smoothing filters has improve diagnostic accuracy. Multi-parameter analysis using DKI combination other image types recently performance. The purpose this study was evaluate usefulness machine learning (ML)-based multi-parameter MK apparent coefficient (ADC) values—which can acquired...
Abstract Objective To investigate the accuracy of artificial intelligence‐assisted growth prediction using a convolutional neural network (CNN) algorithm and longitudinal lateral cephalograms (Lat‐cephs). Materials Methods A total 198 Japanese preadolescent children, who had skeletal Class I malocclusion whose Lat‐cephs were available at age 8 years (T0) 10 (T1), allocated into training, validation, test phases (n = 161, n 17, 20). Orthodontists CNN model identified 28 hard‐tissue landmarks...
Cisplatin is a platinum-based compound that widely used for treating inoperable oral squamous cell carcinoma (OSCC) in Japan; however, resistance to cisplatin presents challenge and innovative approaches are required. We aimed investigate the therapeutic potential of targeting chemokine receptor CXCR4, which involved angiogenesis tumor progression, using CXCR4 inhibitor AMD3100, combination with cisplatin. AMD3100 induced necrosis bleeding OSCC xenografts by inhibiting angiogenesis....
Objectives: To examine radiographically the relationship between deciduous tooth and dentigerous cyst of permanent successor during transitional dentition. Methods: From a retrospective review all patients who visited our institution from April 1988 to August 2001, 70 under 16 years age had histologically confirmed cysts that developed central incisor second premolar were identified. These investigated using panoramic periapical radiographs. Results: In most cases (54 cases; 77.1%) was in...
To focus on the effects of presence mesiodens adjacent teeth and to investigate timing its safe removal.Cone-beam computed tomography examinations, obtained at Okayama University Hospital over a three-year period, were inspected. Data recorded including number mesiodens; associated abnormalities; relationship with neighboring structures. Depending multiple factors, risk developing complications due early extraction was divided into three categories: high, medium, low risk.A total 5,958...
Odontoma is the most common type of benign odontogenic tumor, and often causes disturbances in eruption its associated tooth. Odontomas usually occur permanent dentition, rarely solely primary dentition. This case report documents a six-year-old-child with compound odontoma located mandible, which caused impaction second molar.
