Mid–palatal suture: evaluation of the ossification degree in human skulls

Jussara ENNES, Alberto CONSOLARO

Objectivs: To analyze the mid-palatal suture ossiication rate on human skulls. Sample: Human skulls (28) divided among four groups according to chronological developmental phases: child, teen-ager, adult and elderly. Material: Maxillary Total Occlusal radiographs from different groups of skulls (28). Digitalized images from Maxillary Total Occlusal radiographs (28). Methods: The presence of ossiication bridges on the mid-palatal suture were identiied, registered and qualiied. The radiographs of the skulls were taken using the Maxillary Total Occlusal technique, modifying the horizontal position of the ilm. These radiograph images were digitalized and submitted to brightness and contrast adjustments to investigate mid-palatal suture ossiication rate. Conclusion: The ossiication of mid-palatal suture starts mainly at adult phase and on the posterior segment. The Maxillary Total Occlusal radiographic technique does not provide an adequate image to mid-palatal suture ossiication rate identiication.

Keywords: Mid-palatal suture. Rapid maxillary expansion. Inter-maxillary disjunction. Maxillary total occlusal radiograph.
