Objective: This study aimed to investigate AI-based computer-aided diagnosis (AI-CAD) for panoramic radiographs, especially quantitative evaluation of mandibular cortical morphology in relation to age and gender.
Methods: 321 patients with jaw lesions who underwent panoramic radiography were prospectively included. The mandibular cortical morphology was analyzed with an AI-CAD that evaluated the degree of deformation of mandibular inferior cortex and mandibular cortical index (MCI) automatically. Those were analyzed in relation to age and gender, such as younger (≦ 20 years), middle (21-60 years) and older group (≧ 61 years) in men and women.
Results: The degree of deformation in older men (33.0 ± 18.5) was higher than those of middle (25.0 ± 15.3, p = 0.030) and younger (32.5 ± 16.9, p = 0.993), and those in older women (46.2 ± 22.5) was higher than those of middle (19.4 ± 16.5, p < 0.001) and younger (22.4 ± 14.5, p < 0.001). The MCI of women was a significant difference for aging (p < 0.001), although those of men was not significant difference for aging (p = 0.189).
Conclusion: The AI-CAD could be a useful tool for the quantitative analysis of mandibular cortical morphology.

Aim: This report highlights successful management of a rare case of a mandibular premolar with Oehler's Type IIIb Dens Invaginatus (DI) and peri-invagination periodontitis with guided intentional replantation (IR) without root canal treatment.
Methods: A 22-year-old female patient reported with discomfort and a sinus tract associated with tooth #21. Clinical examination and cone beam computed tomography revealed tooth #21 had an Oehler's Type IIIb DI with peri-invagination periodontitis.
Floor of the Mouth Hemorrhage Following Dental Implant Placement or Guided Bone Regeneration (GBR) in the Atrophic Interforaminal Mandible.

The authors present two cases of mouth floor hemorrhage consequences of implant placement within the atrophic anterior mandible. In one patient, the implant placement was associated with the guided bone regeneration (GBR) technique. This serious complication has been widely described in the literature, especially in the anterior mandible area.

Background: Determining the distal cantilever length in All-on-Four (All-on-4) implant-supported prostheses is a major factor in the long-term success of these prostheses. The difference in mechanical properties of materials used in the fabrication of these prostheses, such as polyether ether ketone (PEEK), may have an impact on the determination of the cantilever length that best distributes stress.
Aim: To study the distribution of stress in All-on-4 mandibular prostheses in the bone, implants, and framework according to difference cantilever length in PEEK prosthetic framework using three-dimensional finite element analysis.
Microstructural Analysis of the Human Scapula: Mandibular Bone Tissue Engineering Perspectives.

Mandibular bone defect reconstruction remains a significant challenge for surgeons worldwide. Among multiple biodegradable biopolymers, allogeneic bone scaffolds derived from human sources have been used as an alternative to autologous bone grafts, providing optimal conditions for cell recruitment, adhesion, and proliferation and demonstrating significant osteogenic properties. This study aims to investigate the bone microstructure of the human scapula as a source for allogeneic bone scaffold fabrication for mandibular tissue engineering purposes.

Objective: This study aimed to investigate the variables affecting the visibility of the submandibular fossa (SF) on panoramic images, including SF depth and types, age, gender, presence or absence of tooth, location of mandibular canal, and alveolar bone thicknesses.
Methods: Cone beam computed tomography (CBCT) images and conventional panoramic images of 150 patients were analyzed retrospectively. The visibility of the SF on panoramic images was compared with its depth and adjacent alveolar bone thicknesses on CBCT.
