Artificial Intelligence Versus Human Dental Expertise In Diagnosing Periapical Pathosis On Periapical Radiographs: A Multicenter Study, Fatma E.A Hassanen, Radwa R. Hussein, Mohamed Riad Elgarhy, Shaymaa Mohamed Maher, Marwa Ezz, Ahmed Hassen, Sherif Heidar, Amr Edress, Asmaa Abou-Bakr

Dentistry

Periapical pathosis in periapical radiographs must be properly diagnosed for the success of endodontic treatment but is often muddled by 2D imaging limitations and subjective interpretation. Artificial intelligence (AI) offers a solution, but whether the diagnostic granularity of AI versus human clinicians in everyday clinical practice has been adequately explored remains to be addressed. The purpose of this study was to evaluate the diagnostic accuracy of ChatGPT-5 in detecting periapical radiographic abnormalities compared with the three-expert consensus reference standard. Methods: In this diagnostic accuracy retrospective study, 270 periapical radiographs were independently read by a large language model (ChatGPT-5) and a …

Dentistry

Objective: This study aimed to compare the accuracy of condylar positioning between 2 computer-guided orthognathic surgical protocols: a waferless screw hole plate locating (WSL CPD) technique versus an occlusal splint with distal extending arms (OWDA-CPD) approach. Materials and Methods: Twenty-four patients requiring mandibular orthognathic surgery (class II or III deformities) were randomly allocated into 2 groups (n=12 each). Group I underwent a waferless protocol utilizing 3D-printed osteotomy and screw hole locating guides, while group II received an occlusal splint with distal extensions for condylar positioning. Preoperative and postoperative cone-beam computed tomography (CBCT) scans were used to assess condylar displacement in …

Dentistry

Aim: This study aimed to compare digitally fabricated auricular prostheses to conventional prostheses, regarding adaptation to defect site in patients with auricular defects.

Subjects and methods: Fifteen patients were recruited for auricular prosthetic reconstruction. Endosseous implants were placed, then patients were assigned into two groups. In control group, ear models were processed on stone cast obtained from conventional impression. In intervention group, computed tomography and optical scanning were combined to obtain a virtual model with digital analogues over which ear models were designed and printed. Ear models of both groups were seated, and adaptation was measured on the patient using …

Clinical Effectiveness Of High Definition Fluorescence Camera In Detection Of Initial Occlusal Caries, Mohamed Salama, Olfat Hassanein, Omar Shaalan, Asmaa Yassen

Dentistry

Background: Although visual inspection is the preferred route in everyday clinical practise for detecting early caries lesions, novel technologies like light fluorescence-based devices (Vista Proof iX HD smart) have been developed to enhance early caries detection. Material and Methods: Occlusal surface of 45 molar and 49 premolar teeth from 34 adult participants who fulfilled the eligibility criteria were examined by two observers using three diagnostic methods. Examination was performed visually using the International Caries Detection and Assessment System (ICDAS-II) followed by Vista Proof. Fissurotomy was applied for histological validation. Intra- and inter-observer agreement were measured for ICDAS-II and light-induced fluorescence …

Cone Beam Computed Tomography Versus Intraoral Digital Radiography In Detection And Measurements Of Simulated Periodontal Bone Defects Diagnostic Accuracy Study, Marwa Ezz, Hossam Kandil

Dentistry

Detection and accurate assessmentof periodontal disease is important to determine the tooth prognosis and treatment. Radiographic assessment provides information about the pattern and extent of the alveolar bone loss. Digital radiography has ability to enhance images and make direct measurements. CBCT provides unique 3D images used for diagnosis and treatment plans, but its use in periodontology not well-reviewed as there is few number of studies searched about the role of CBCT in periodontology. We compare digital radiography with CBCTin the detection and measurements of different bone defects. Dry jaws with simulated bone defects were imaged by CBCT and Digital radiography …

Materials and methods The authors performed a cross‑sectional study with 605 adult dental patients. All patients filled a questionnaire inquiring about the risk factors. An oral examination was performed to each participant to determine presence or absence of oral ulcers; and the type of the oral …

The Effect Of Smoking On Clinical Presentation And Expression Of Tlr-2 And Cd34 In Oral Lichen Planus Patients: Clinical And Immunohistochemical Study, Enji Ahmed Mahmoud, Nermin Yousif, Nermin Raouf

Dentistry

Background: Oral lichen planus is a chronic inflammatory disease which is considered as a potential precancerous condition. Numerous studies have confirmed that inflammation is a strong risk factor for cancer development. Smoking is associated with potentially malignant disorders of the oral and oropharyngeal mucosa. The adverse consequences of smoking in various pathologies are mediated by its effects on the immune-inflammatory system. Little is known about the influence of cigarette smoke content on the course of OLP and inflammatory response. Methods: Twenty oral lichen planus smoker patients, 20 oral lichen planus non-smoker patients and 20 control patients were included in this …

Expression Of Endocan And Vascular Endothelial Growth Factor In Recurrent Minor Aphthous Ulcers, Enji Ahmed Mahmoud, Wesam Abdelmonem, Olfat Gamil Shaker, Dalia Mohey-Eldien Ghalwash

Dentistry

Background: Recurrent aphthous ulcers (RAU) are common painful inflammatory lesions of the mucous lining of the mouth. Endocan, previously identified as endothelial cell specific molecule-1, is implicated as a vital player in the regulation of several inflammatory processes. A number of inflammatory cytokines and pro-angiogenic growth factors including VEGF upregulate endothelial cells synthesis and expression of endocan. Material and Methods: Clinical scores of pain and ulcer size as well as level of endocan and VEGF were determined in swaps from aphthous ulcer and contra lateral normal mucosa in 30 patients (nine males and twenty one females) with age ranging from …
