High glucose condition aggravates inflammatory response induced by Porphyromonas gingivalis in THP-1 macrophages via autophagy inhibition.

Background: Porphyromonase gingivalis (P. gingivalis) is a type of bacteria that causes periodontitis, which is strongly correlated with systemic diseases such as diabetes. However, the effect of hyperglycemia on periodontitis are unclear.

Myxoid lipoma in the perioral mandibular region: two case reports.

Lipomas are one of the most common mesenchymal tumors in the human body, exhibiting a heightened prevalence between the ages of 40 and 60 years. However, primary intraoral lipomas are rare. Myxoid lipoma, which is characterized by abundant mucoid components, is a particularly rare histological subtype of lipoma.

Delayed Soft Tissue Changes after Clockwise Rotation of the Maxillo-Mandibular Complex.

Objective: The purpose of this study was to evaluate delayed soft tissue changes of the maxilla-mandibular complex MMC using three-dimensional (3D) cone-beam computed tomography after clockwise repositioning orthognathic surgery.

Methods: This study included 21 patients that underwent maxilla-mandibular complex clockwise rotational orthognathic surgery by 1 doctor from January 2015 to June 2019. Radiographic images (panorama, lateral cephalogram, posteroanterior view, and conebeam computed tomography) were taken and 3D analysis was performed using the Invivo 5 (Anatomage Inc, Santa Clara, CA) to acquire 3D images before surgery, immediately after surgery, at 6 months after surgery and 21 months after surgery.

Effects of photobiomodulation on bone remodeling in an osteoblast-osteoclast co-culture system.

The general bone anabolic effect of photobiomodulation (PBM) is largely accepted. As a result, PBM therapy is expected to be beneficial in the medical fields of dentistry and bone healing. However, most of the previous in vitro studies on PBM and bone metabolism were performed with single-cell cultures of osteoclast-lineage cells or osteoblast-lineage cells.

Automatic three-dimensional analysis of bone volume and quality change after maxillary sinus augmentation.

Introduction: Maxillary sinus augmentation is a widely used surgical procedure to increase the bone volume before implant placement. In order to predict the stability of the implant, analysis of the change in bone volume and quality after a sinus graft procedure is necessary. The purpose of this study was to analyze the change in volume and quality of bone graft material after maxillary sinus augmentation using cone beam computed tomography (CBCT).
