Background: Dental mutilations (DM) were and are still common among people in Africa. The purpose of this study was to examine DM in 33 skulls from Cameroon, which have been collected around the turn of the 20th century (anthropological collection, Berlin Museum of Medical History).
Materials And Methods: From the files of the museum, locations and/or tribal origin were recorded. DM classification described by De Almeida was used (1957).
Results: DM of the inverted V-shaped type was most common (30.3%). Pulp exposure was seen in 10 cases (30.3%). Periapical ostitis/radicular cysts were seen in nine cases (27.3%). General loss of alveolar bone was seen in all cases with a marked loss of the maxillary anterior labial alveolar bone plate in six cases (18.2%).
Conclusions: DM may result in alveolar bone pathology characterised by inflammatory changes such as periapical ostitis or formation of radicular cysts.

Delayed tooth extraction socket (TES) healing can cause failure of subsequent oral implantation and increase socioeconomic burden on patients. Excessive amounts of M1 macrophages, apoptotic neutrophils (ANs), and neutrophil extracellular traps (NETs) impair alveolar bone regeneration during TES healing. In the present study, we first discovered that conditioned medium (CM) collected from berberine-treated human bone marrow mesenchymal stem cells (BBR-HB-CM) accelerated TES healing.

Objectives: WNT10A mutations are associated with tooth agenesis. This study aimed to assess the clinical outcomes of dental implants in patients carrying WNT10A mutations with different molecular statuses and phenotypes over a long-term follow-up period.
Materials And Methods: Patients with tooth agenesis were screened by whole-exome sequencing (WES) from January 2010 to September 2023.

Aim: To propose a modified method for establishing a peri-implantitis murine model, assess the gene expression profile and immune cell infiltration of the gingiva and alveolar bone, and evaluate the transcriptomic similarity between patients with peri-implantitis and the corresponding murine model.
Materials And Methods: A ligature-induced peri-implantitis murine model was established using an immediate implant placement approach. RNA sequencing was performed to determine the transcriptomic profiles of peri-implant tissues from mice, patients with peri-implantitis and healthy individuals.

Periodontitis is a chronic inflammatory disease that destroys tooth-supporting structures and poses significant public health challenges due to its high prevalence and links to systemic health conditions. Traditional treatments are effective in reducing the inflammatory response and improving the clinical symptoms of periodontitis. However, these methods are challenging to achieve an ideal treatment effect in alveolar bone repair.

Background: Aesthetics is a crucial consideration in the anterior region, alongside dental implant survival and marginal bone loss (MBL). Bone-level implants are advantageous in the esthetic zone as they create a natural emergence profile with the use of customized abutments. This study aimed to assess the esthetic outcomes of internally submerged, tapered, bone-level dental implants and to evaluate associated alveolar bone changes.
