Endoscopic sinus surgery poses unique training challenges due to complex and variable anatomy, the risk of major complications. We sought create provide validity evidence for a novel 3D-printed simulator nose paranasal sinuses.Sinonasal computed tomography (CT) images patient were imported into 3D visualization software. Segmentation bony soft tissue structures was then performed. The model printed using simulated bone materials. Rhinologists otolaryngology residents completed 6 prespecified...
Background The incidence of colorectal cancer (CRC) is increasing nationally, emphasizing the importance early detection. Late-stage diagnosis, particularly with peritoneal metastasis (PM), associated poor outcomes despite advancements in treatment. PM poses a challenge owing to lack standardized treatment, although cytoreductive surgery (CRS) hyperthermic intraperitoneal chemotherapy (HIPEC) shows promise improving survival rates. This study aimed document and risk factors for patients...
Patients with head and neck squamous cell cancer (HNSCC) are at a greater risk of developing pulmonary metastases and/or second primary lung cancer. However, it remains uncertain whether screening in these patients, when the initial staging studies negative, confers any survival benefit. To evaluate long-term outcomes patients HNSCC undergoing chest radiography vs low-dose computed tomography for metastasis This randomized parallel trial was conducted large academic hospital Canada enrolling...
Advancements in endoscopic sinus and skull base surgery created a need for standardized terminology to describe sphenoid surgery. Although classification systems exist other sinuses, one is lacking. Developing such system would standardize procedure descriptions promote common language among surgeons. This study aimed develop new Consensus on novel by running the Delphi with 16 rhinology experts from around world. Four rounds were required reach consensus all stages of classification. The...
Interleukin-10 regulates pro-inflammatory cytokines, including those implicated in alveolar bone resorption. We hypothesized that lack of interleukin-10 leads to increased Male interleukin-10(−/−) mice, on 129/SvEv and C57BL/6J background, were compared with age-, sex-, strain-matched interleukin-10(+/+) controls for loss. Immunoblotting was used analysis serum reactivity against bacteria associated colitis periodontitis. Interleukin-10(−/−) mice had significantly greater loss than (p =...
Many risk factors that might contribute to the pathogenesis of atherosclerosis have been proposed, including chronic inflammation and infection. Furthermore, systemic inflammatory responses periodontal bacteria suggested as a pathogenetic link between disease atherosclerosis. The purpose this study was estimate white blood cell (WBC) platelet counts in periodontitis patients.Fifty patients with 50 healthy periodontium were included study. Oral hygiene status, pocket probing depth (PPD)...
Background: Use of collagen membrane (CM) with xenograft and recombinant human platelet‐derived growth factor (rhPDGF) in guided bone regeneration (GBR) is debatable. The aim this microcomputed tomographic experiment was to assess the efficacy using PDGF (with or without CM) for GBR around immediate implants dehiscence defects. Methods: Ten beagle dogs underwent atraumatic bilateral second fourth premolar extractions from both arches. A standardized defect (6 × 3 mm) created on buccal were...
Objective and background: Interleukin‐10 (IL‐10) is an anti‐inflammatory cytokine regulating immune responses. We have previously reported that IL‐10(–/–) mice experience accelerated alveolar bone loss. The purpose of the present study was to examine timing manifestation loss in mice. Materials methods: Twenty‐four 21 IL‐10(+/+) age‐matched male 129/SvEv were used. Sacrifice times occurred at 1, 3 9.5 months age. Alveolar determined morphometrically on defleshed jaws. Enzyme‐linked...
Background: Previous studies assessed bone remodeling after a single tooth extraction; however, the effect of multiple contiguous teeth extractions around immediate implant remains unknown. The aim this microcomputed tomographic investigation is to analyze alveolar implants placed in accordance with extraction socket classification (ESC). Methods: Under general anesthesia, 10 beagle dogs underwent atraumatic extractions. Animals were randomly divided into three groups, 16 sites per group: 1)...
To determine the clinical features of patients with chronic rhinosinusitis at a tertiary hospital in Riyadh, Saudi Arabia.A cross-sectional study was carried out King Abdulaziz University Hospital, Arabia. We enrolled 660 male and female participants medical records indicating history between 2021 2022. Quantitative descriptive analyses age, gender, nationality, presence polyps, aspirin sensitivity, urticaria, asthma, allergies were performed.Of patients, 60% (n=396) 40% (n=264) female....
To study the osseointegration of dental implants placed with a modified surgical technique in Beagle dogs and to compare it conventional method.Dental were bilaterally mandible using press-fit as well undersized implant bed preparation technique. Micro computer tomography (micro-CT) histometric methods used analyze bone contact volume (BV) around implants.The bone-to-implant percentage (BIC: expressed %), first BIC (1st BIC: mm), sulcus depth (SD: mm) connective tissue thickness (CT:...
Several factors cause relapse of orthodontically de-rotated teeth after appliance removal. Circumferential supracrestal fiberotomy (CSF) may release the tension on supra-alveolar fibers following tooth de-rotation, thereby reducing risk. However, careful identification amount and location enables proper clinical evaluation. We aimed to determine orthodontic CSF for anterior teeth.Eleven patients with 90 were enrolled. was performed treatment, during fixed retainer placement. Rotational...
Periodontal regenerative techniques have been proposed; however, the outcomes remain debatable. The present investigation assessed regenerated cementum following enamel matrix derivative application in dehiscence‐type defects. Buccal osseous dehiscences were surgically created on maxillary cuspid, and second fourth premolars five female beagle dogs. treatment group (n=15 sites) received derived application, whereas control groups (n=15) did not. dogs sacrificed 4 months specimens...
Background: Vertical bone augmentation (VBA) remains unpredictable and challenging for most clinicians. This study aims to compare hard tissue outcomes of VBA, with without recombinant human morphogenetic protein (rhBMP)‐2, under space‐making titanium mesh in a canine model. Methods: Eleven male beagle dogs were used the study. Experimental ridge defects created form atrophic ridges. VBA was performed via guided regeneration using allografts. In experimental hemimandibles, rhBMP‐2/absorbable...
