AI Article Synopsis
- The study examined how dental defects and gum diseases affect jaw function, focusing on both quantity and quality of changes.
- It found that there was muscle dysfunction and unbalanced interactions between the muscles that work together in the jaw.
- The coordinated activity of the jaw muscles decreased significantly with the severity of dental defects: 56.4% disordered in class I, 70.5% in class II, and 83.3% in class III defects.
Article Abstract
Quantitative and qualitative changes of the function of the jaws in dentition defects and periodontal diseases were assessed. Besides dysfunction of every muscle involved, disordered relationships between antagonist and synergic muscles were revealed. Coordinated activity of maxillofacial muscles was 56.4% disordered in class I defects of dentition, 70.5% impaired in class II defects, and 83.3% disordered in class III defects.

The aim of this study was to explore the factors influencing the quality of new bone formation after distraction osteogenesis in children with Pierre Robin sequence (PRS). Using cone-beam computed tomography (CBCT), bone density relative grayscale values of the region of new bone formation before and 3 to 4 months after mandibular distraction osteogenesis (MDO) were measured in 80 children with PRS, and correlation analysis was conducted with the potential clinical influencing factors of the children. CBCT reconstruction of the panoramic film showed that the new bone formation was good at 3 to 4 months after MDO.

Background: Myoepithelial carcinoma is a very rare yet aggressive tumor in children. Surgical intervention and local radiotherapy often lead to post-therapy complications, affecting both the aesthetic and functional quality of life in survivors. Hyaluronic acid (HA) dermal fillers offer a minimally invasive option to improve the appearance and quality of life for these patients once they are declared tumor-free.
