Article Synopsis
- This study focuses on the changes in palatal rugae (the ridges on the hard palate) following orthodontic treatment, investigating whether their shape, complexity, and area are affected by treatment with or without tooth extractions.
- Researchers analyzed pre- and post-treatment plaster models from a sample of 61 cases, using advanced software to measure changes in the outlines, fractal dimensions (complexity), and area occupied by the rugae.
- Results showed significant differences in the distance between pre- and post-treatment outlines for extraction versus non-extraction groups, but no significant changes in the complexity of the rugae before and after treatment.
In an era of increasing life expectancy and growing patient demands towards lifelong natural tooth retention, accurate assessment of gingival recessions is crucial for diagnosing periodontal diseases, planning preventive or restorative interventions, and evaluating their outcomes. The traditional two-dimensional (2D) methods, while useful, often fall short in capturing the complex topography of gingival tissue margins and their changes over time. By examining relevant published studies, this review highlights the transition from 2D to 3D techniques, analyzing the limitations of widely used 2D approaches, while emphasizing the potential of novel 3D tools and techniques.

- Sleep apnea, specifically obstructive sleep apnea (OSA), is linked to tooth loss (edentulism), which can worsen breathing during sleep, showing a positive relationship across 23 clinical studies reviewed from 1999 to 2023.
- The severity of OSA tends to increase with the extent and duration of tooth loss, with edentulous patients showing significantly higher apnea-hypopnea index scores compared to those with teeth.
- While there is evidence supporting the association between edentulism and OSA, the research is limited and sometimes inconsistent, indicating the need for more extensive studies to clarify these findings.
Background/objectives: It is unclear whether palatal canine impaction is related to genetic or local/environmental factors. If a genetic origin is assumed, then it could be expected that palatal canine impaction is associated with overall craniofacial development. Within this context, the aim of this study was to evaluate the craniofacial morphology of individuals with palatal canine impaction and compare it to a matched group of normal controls.

Here, we aimed at creating a 3D atlas of the human mandible in an adult sample using dense landmarking and geometric morphometrics. We segmented 50 male and 50 female mandibular surfaces from CBCT images (age range: 18.
