Abstract Background This study explored dental students’ and dentists’ perceptions attitudes toward artificial intelligence (AI) analyzed differences according to professional seniority. Methods In September November 2022, online surveys using Google Forms were conducted at 2 colleges on websites. The questionnaire consisted of general information (8 or 10 items) participants’ perceptions, confidence, predictions, perceived future prospects regarding AI (17 items). A multivariate logistic...

Periodontitis is initiated by causative bacteria in the gingival sulcus. However, as lesion often deep and out of circulation system biofilm frequently formed on cluster, use antibacterial agents has been limited invasive method such curettage thought an only treatment. Here we designed non-invasive photodynamic therapy (PDT), with ointment which leads a photosensitizer deliverable into We assessed whether 650 nm light-emitting-diode (LED) penetrates 3-mm soft tissue effectively activates...

Odontomas, which are formed from an overgrowth of epithelial and mesenchymal cells, 1 classified as benign, one the most commonly occurring types odontogenic tumors. 2 Due to their limited slow-growing characteristics, they considered be hamartomas.Odontomas subdivided into compound complex odontomas depending on degree differentiation tooth material gross similarities normal teeth in terms whether have crowns roots. 3Generally, do not exceed 3 cm diameter. 4However, some rare cases, large ,...

This study suggests a hybrid method based on ResNet50 and vision transformer (ViT) in an age estimation model. To this end, panoramic radiographs are used for learning by considering both local features global information, which is important estimating age. Transverse longitudinal images of 9663 patients were selected (4774 males 4889 females with mean 39 years 3 months). compare ResNet50, ViT, the model, absolute error, square root coefficient determination (R2) as metrics. The results...

Ultraviolet B (UVB) radiation induces photoageing by upregulating the expression of matrix metalloproteinases (MMPs) in human skin cells. Dihydroavenanthramide D (DHAvD) is a synthetic analog to naturally occurring avenanthramide, which active component oats. Although anti-inflammatory, anti-atherosclerotic and antioxidant effects have been reported, antiphotoageing DHAvD are yet be understood. In this study, we investigated inhibitory on UVB-induced production reactive oxygen species (ROS)...

In this paper, we present the result of investigations pertaining to pipe stiffness (PS) glass fiber reinforced polymer plastic (GFRP) flexible pipes buried underground. PS formula for parallel plate loading condition is derived based on elasticity theory. Vertical and horizontal displacements are also derived. study, mechanical properties structural behavior GFRP investigated experimentally results used in analysis design these pipes. Pipe by test, finite element analysis, theoretical...

Langerhans cell histiocytosis is a rare disease of unknown pathogenesis involving clonal proliferation cells. 1 The term "Langerhans histiocytosis" was introduced by the Writing Group Histiocyte Society, 2 replacing X, which had been proposed in 1953 Lichtenstein 3 and encompassed disorders: eosinophilic granuloma, Hand-Schüller-Christian disease, Letterer-Siwe disease.Eosinophilic granuloma most benign common form histiocytosis, it involves localized lesions predominantly bones. 4It...

High glucose leads to physio/pathological alterations in diabetes patients. We investigated collagen production human gingival cells that were cultured high concentrations of glucose. Collagen synthesis and secretion increased when the exposed examined endoplasmic reticulum (ER) stress response because metabolism is related ER functional status. An including expression regulated protein 78 (GRP78), C/EBP homologous (CHOP), inositol requiring enzyme alpha (IRE-1α) phosphoreukaryotic...

The aim of this study was to present a method for endodontic management maxillary first molar with unusual C-shaped morphology the buccal root verified by cone-beam computed tomography (CBCT) images. This rare anatomical variation confirmed using CBCT, and nonsurgical treatment performed meticulous evaluation pulpal floor. Posttreatment image revealed 3 independent canals in obturated efficiently accepted lengths all canals. Our describes unique canal system molar, involving In addition, our...

Glandular odontogenic cyst (GOC) is known as a slowly growing, painless, but aggressive lesion.The potentially nature of the lesion was suggested by penetration cortical bone and high incidence recurrence after conservative treatment. 1GOC rare with an 0.2% cysts. 2 It affects males twice frequently females mandible almost three times maxilla. 3The age range 14-75 years, mean 45.7 years. recently described cystic among 4In 1987, Padayachee Van Wyk 5 first reported sialo-odontogenic cyst;...

The aim of this pilot study was to examine the kinetics alterations in alveolar ridge width and height following tooth extraction with without preservation, using anorganic bovine bone mineral (ABBM) a novel device (SocketKAP(™) ) designed for obturation socket orifice.Maxillary left right PM1 mandibular PM2 PM4 were extracted on six beagle dogs treated as follows: Group A: negative control; B: SocketKAP(™) alone; C: ABBM + . Serial cone-beam computed tomography (CBCT) taken at 0-, 1-, 2-,...

Fibrous dysplasia (FD) is an uncommon skeletal disorder in which normal bone replaced by abnormal fibro-osseous tissue. Mainly, FD found children, and adulthood it usually becomes quiescent. Our case showed of more than 14-year duration the left maxilla. evaluation was that growth ceased had achieved static stage. Because cases elderly patients are rarely reported, we hereby present a monostotic 65-year-old female. We presented sequential radiographic images scintigraphic this case, combined...

Mucocele of the paranasal sinuses is a benign, slow-growing, expansile lesion. Maxillary sinus mucoceles are usually associated with painless bulging cheek; however, orbital expansion rarely observed. can be classified as primary or secondary according to their etiology. An impediment ostium ventilation thought cause mucocele, while sequestering residual mucosa after surgery in wound and long-term retention tissue fluid have been suggested lead formation mucocele. This report presents 2...

This study was designed to evaluate whether magnetic resonance imaging (MRI) is appropriate for detecting early changes in the mandibular bone marrow and pulp tissue of rats after high-dose irradiation.The right mandibles Sprague-Dawley were irradiated with 10 Gy (Group 1, n=5) 20 2, n=5). Five non-irradiated animals used as controls. The MR images rat obtained before irradiation once a week until 4 irradiation. From images, signal intensity (SI) incisor interpreted. compared histopathologic...

Let [Formula: see text] be a prime number and positive even integer less than text]. In this paper, we find the strongly divisible modules corresponding to Galois stable lattices in each 2-dimensional semi-stable non-crystalline representation of with Hodge–Tate weights whose mod-[Formula: reductions are nontrivial extensions two distinct characters. We use these results construct irreducible components deformation rings non-split reducible residual representations

Radiotherapy, although used worldwide for the treatment of head, neck, and oral cancers, causes acute complications, including effects on vasculature immune response due to cellular stress. Thus, ability diagnose side-effects monitor vascular in real-time during radiotherapy would be highly beneficial clinical research applications. In this study, recently-developed fluorescence micro-endoscopic technology provides non-invasive, high-resolution, imaging at level. Moreover, with application...
