Diabetes mellitus and periodontitis share a significant, bidirectional relationship. Diabetes raises the risk of periodontitis and influences its severity, impacting tissue repair and bone metabolism. Conversely, periodontal inflammation can disrupt glycemic control, further complicating this interlinked relationship.

LIPUS promotes osteogenic differentiation of rat BMSCs and osseointegration of dental implants by regulating ITGA11 and focal adhesion pathway.

BMC Oral Health

January 2025

Beijing Institute of Dental Research, Beijing Stomatological Hospital, School of Stomatology, Capital Medical University, Beijing, China.

Background: Low-intensity pulsed ultrasound (LIPUS) has been used as an effective noninvasive method for treating fractures and osteoarthrosis, but the application in the field of oral implantation is in its infancy. This study aimed to clarify the effect and mechanism of LIPUS on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and implant osseointegration, and to provide an experimental basis for future clinical applications.

Methods: Dental implants were inserted into Wistar rat femurs, and LIPUS was performed for 4 weeks.

Full-arch implant rehabilitation in extremely atrophic edentulous mandibles is still challenging due to the high risk of fracture and the limited bone availability. The approach proposes using short implants with immediate loading for final prostheses as a treatment option, which offers shorter treatment times and fewer invasive procedures. A 66-year-old female patient with an edentulous mandible and severe alveolar bone resorption was treated with four short implants in the interforaminal area.

Article Synopsis
  • - The study aimed to assess how effective a gel with active oxygen is in preventing Medication-Related Osteonecrosis of the Jaw (MRONJ) in a rat model.
  • - Twelve rats underwent surgery after receiving a drug (zoledronate) known to cause osteonecrosis and were divided into two groups: one treated with oxygen gel and the other left untreated.
  • - Results showed that the untreated group had more severe MRONJ symptoms, suggesting that the gel may help in preventing this condition, although further research is needed due to the pilot nature of the study.

Heliyon

November 2024

Department of Orthodontics, School of Stomatology, Beijing Stomatological Hospital, Capital Medical University, No.4 Tiantan Xili, Dong cheng District, Beijing, 100050, China.

Pathogenic genes in most patients with cleidocranial dysplasia have been confirmed to be runt-related transcription factor 2 (), which controls mutations in specific osteoblast transcription factors and affects skull ossification and suture adhesion. This study aimed to explore the role of mutations. Here, we report a rare case of a splice site mutation in a Chinese population with typical cleidocranial dysplasia symptoms, cranial suture insufficiency, clavicle dysplasia, and dental anomalies.

Effect of ultraviolet treatment on soft tissue healing and bacterial attachment to titania-coated zirconia.

Biomed Mater

November 2024

Beijing Institute of Dental Research, School of Stomatology, Capital Medical University, Beijing 100050, People's Republic of China.

Zirconia is the most promising implant abutment material due to its excellent aesthetic effect, good biocompatibility and corrosion resistance. To obtain ideal soft tissue sealing, the implant abutment surface should facilitate cell adhesion and inhibit bacterial colonization. In this study, pre-sintered zirconia was placed in a suspension of titania (TiO) and zirconium oxychloride (ZrOCl) and heated in a water bath for dense sintering.

Article Synopsis
  • Effective management of unique anatomical structures, like the nasopalatine canal, is crucial for implant success, and topical oral oxygen therapy (TOOT) has emerged as a promising treatment due to its antibacterial and healing properties.
  • A case involving a 33-year-old male showed postoperative palatal necrosis treated with TOOT gel after surgical intervention for a deficient maxillary ridge.
  • The patient experienced significant healing within 12 days and complete recovery by day 34, suggesting TOOT with active oxygen gel can enhance wound healing in dental procedures.

Oral lichen planus (OLP) is a chronic inflammatory disease that is associated with an increased risk of carcinogenesis. The typical pathological features of OLP include submucosal T-cell banding, infiltration, and liquefactive degeneration of basal epithelial cells. However, the histological appearance of basal cell death cannot be explained by apoptosis of keratinocytes alone.

Medication-related osteonecrosis of the jaw (MRONJ) can be a debilitating complication that can arise in patients who took or are taking antiresorptive (including bisphosphonates) or antiangiogenic agents, leading to visible bone or a fistula that continues for more than eight weeks, without any history of radiotherapy. This clinical case aimed to describe the treatment of MRONJ with topical active oxygen therapy using bluem oral gel. A 63-year-old female patient that had been taking weekly sodium alendronate (70 mg) for four years by oral via, presented discomfort and implant movement in the #46 region, by that underwent surgical extraction of the implant.
