The palatine suture is wider in 6-14-year-old children with diastema than in normal ones; this suture is commonly direct and rarely tortuous. This may be due to its inadequate ossification. The width of the diastema does not depend on the suture width. An acuminate interalveolar septum predominates in normal children, but diastema and the child's age are conducive to its flattening. Orthodontic treatment normalizes the width of the palatine suture and the shape of the interalveolar septum, but in many patients the results are not stable.

Morphometric analysis of the greater palatine foramen: a CBCT study in Portugal.
Surg Radiol Anat
January 2025
Faculty of Dental Medicine, University of Porto, Porto, Portugal.
Purpose: The greater palatine foramen (GPF) represents the inferior opening of the greater palatine canal and is located posterolaterally on both sides of the hard palate. The aim of this study is to morphometrically characterise the GPF and to determine its anatomical relationships in a Portuguese population.
Methods: A retrospective study was performed based on the clinical records which included all permanent teeth erupted and a cone beam computed tomography (CBCT) of the entire maxilla.
Palatal segment contributions to midfacial anterior-posterior growth.
J Anat

Department of Anthropology, Stony Brook University, Stony Brook, New York, USA.
Anterior-posterior (A-P) elongation of the palate is a critical aspect of integrated midfacial morphogenesis. Reciprocal epithelial-mesenchymal interactions drive secondary palate elongation that is coupled to the periodic formation of signaling centers within the rugae growth zone (RGZ). However, the relationship between RGZ-driven morphogenetic processes, the differentiative dynamics of underlying palatal bone mesenchymal precursors, and the segmental organization of the upper jaw has remained enigmatic.

Exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in utero can result in osteogenic defect during palatogenesis, but the effects on other craniofacial bones and underlying mechanisms remain to be characterized. By treating pregnant mice with TCDD (40 μg/kg) at the vital craniofacial patterning stages (embryonic day 8.5, 10.

Department of Orthodontics, Beijing Stomatological Hospital, Capital Medical University, 100050, Beijing, China.
Purpose: We aimed to investigate early effects of regulating alpha‑7 nicotinic acetylcholine receptor (α7nAChR) agonists and antagonists on maxillary expansion in mice.
Methods: We allocated 36 six-week-old male C57BL/6J mice into three group: 1) expansion alone, 2) expansion plus the α7nAChR-specific agonist 3‑(2,4-dimethoxybenzylidene)-anabaseine dihydrochloride (GTS-21), and 3) expansion plus alpha-bungarotoxin (α-BTX), a competitive antagonist of α7nAChR. The groups were daily injected with saline, GTS-21 (4 mg/kg/day) or α‑BTX (1 mg/kg/day), respectively, from days 0-7.
Age-dependent effects of Delaire facemask therapy for class III malocclusion : Impact on maxillary sutures and palatal morphology.
J Orofac Orthop
December 2024
Department of Orthodontics, Saarland University, 66424, Homburg/Saar, Germany.
Background And Aim: Treatment effects of a combined rapid maxillary expansion (RME) and Delaire facemask (DFM) therapy have so far only been scientifically investigated through cephalometric analyses. The combination of cephalometric, dental cast and cone-beam computed tomography (CBCT) scan analysis was not yet used for investigating morphologic changes of the tooth-bearing palate. The aim of the present study was to determine whether patient age at treatment begin has an influence upon palatal length changes after RME/DFM therapy, and to what extent transverse palatal sutures contribute to these.
