There is a close relationship between perception of umami, which has become recognized as the fifth taste, and human physical condition. We have developed clinical test for umami taste sensitivity using filter paper disc with range six monosodium glutamate (MSG) concentrations. recruited 28 patients disorders (45–78 years) 184 controls no (102 young [18–25 years] 82 older [65–89 participants). Filter discs (5 mm dia.) were soaked in aqueous MSG solutions (1, 5, 10, 50, 100 200 mM), then...
We analyzed the diagnostic performance of MR imaging findings parotid, submandibular, and sublingual glands to discriminate between patients with without Sjögren's syndrome.We retrospectively correlation histopathological obtained from 69 clinically suspected syndrome. evaluated heterogeneous signal intensity distribution on T1- T2-weighted images, multiple high-signal-intensity spots sialograms, volume salivary glands.The in parotid gland showed highest sensitivity accuracy (82% 83%,...
Abstract Background The impact of the jaw bone condition, such as quantity and quality in implant placement site, affecting accuracy with computer-guided surgery (CGS) remains unclear. Therefore, this study aimed to evaluate influence i.e., density, width, cortical thickness at crestal on CGS. Methods A total 47 tissue-level implants from 25 patients placed posterior mandibular area were studied. Implant position was planned simulation software, Simplant® Pro 16, by superimposing...
Children are sensitive to radiation; therefore, it is necessary reduce radiation dose as much possible in pediatric patients. In addition, crucial investigate the optimal imaging conditions they considerably affect dose. this study, we investigated effect of different on image quality and optimized for dental cone-beam computed tomography (CBCT) examinations diagnose ectopic eruptions impacted teeth children. To achieve our aims, evaluated doses subjective objective quality. The CBCT scans...
Abstract Background We aimed to construct an artificial intelligence‐based model for detecting oral cancer and dysplastic leukoplakia using cavity images captured with a single‐lens reflex camera. Subjects methods used 1043 of lesions from 424 patients squamous cell carcinoma (OSCC), leukoplakia, other mucosal diseases. An object detection was constructed Single Shot Multibox Detector detect diseases their locations images. The trained 523 cancer, its performance evaluated ( n = 66), 49),...
Abstract – The purpose of this study was to investigate the effect an increase in laser power on transmitted signals from vital and non‐vital teeth, hope achieving a better assessment human pulp vitality with laser‐light flowmeter. experiments were carried out total 61 teeth no restoration (19 upper central incisors, 16 lateral canines, 10 first premolars) five incisors (the root canals which filled gutta‐percha) 15 subjects aged 22–28 years. For use light, fibers within probe conventional...
Objectives: To evaluate the usefulness of heavily T2 weighted (T2W) magnetic resonance (MR) images for differential diagnosis parotid tumours. Methods: Conventional T2W and obtained from 43 patients with tumours were reviewed retrospectively. Tumours classified pathologically into three types: pleomorphic adenoma (25 cases), Warthin's tumour (7 cases) malignant (11 cases). During interpretation each MR image, special attention was paid to homogeneity signal intensity displayed by solid...
We analysed the correlation between magnetic resonance images of parotid and submandibular glands salivary flow rate in patients with Sjögren's syndrome.We retrospectively reviewed (heterogeneous signal-intensity distribution gland volume on T1- fat-suppressed T2-weighted images, multiple high-signal-intensity spots sialograms glands) obtained from 66 who were diagnosed syndrome. evaluated relationship these imaging features their rates stimulated unstimulated conditions.We found that as...
To determine the risk of developing symptoms due to presence maxillary and mandibular third molars, we analyzed a reliable population sample by age, according third-molar position impaction level using long-term follow-up data under conditions good oral hygiene. Of 308 graduates from our dental school, total 776 molars were followed up for periods 11 27 years means intraoral radiographs. The development symptoms, participant's angular degree investigated. For both symptom correlated neither...
Idiopathic condylar resorption (ICR) is a morphological change of the head that occurs following orthodontic treatment or orthognathic surgery. This complication serious, as it can cause relapse after mandible treatment. The aim this experimental study was to evaluate mechanism influence on compressive mechanical stress in temporomandibular joint occlusal position by advancement.An osteotomy procedure at midline performed 15 rabbits, with left side moved forward 3.5 mm. Advancement resulted...
The purpose of the present study was to investigate efficacy perioperative oral managements (POMs) on nutritional conditions in patients undergoing surgery with general anesthesia. Medical records were retrospectively reviewed and effects POMs investigated based a large number cases using multicenter analysis. profile serum albumin levels assessed compared between without multivariate Seventeen Eleven thousand one hundred sixty (4,873 males 6,287 females) reviewed. Of these, 2710 (24.3%) had...
