Abstract

Abstract: Objective: To investigate the anatomical variability of greater palatine groove (GPG) and to explore its relationship with palatal vault morphology of young Han population. Methods: Cone-beam computerized tomography (CBCT) images of 214 young patients were measured. The morphology and relative locations, as well as the above mucosal thickness, of GPG were assessed and the relationship of the palate vault morphology was discussed. Results: 98.0% male and 98.2% female subjects were found at least onegreater palatine groove.Depending on morphology, all grooves were divided into depressed type, deepgroove with crest type, double grooves type, and tubular type. The distance between GPG and the relative molar's CE Jin the male was longer thanthat of the female(P<0.05). It was the same with the mucosal thickness of the GPG at the second molar.The distance of GPG-CEJin high-vault group was longer than low-vault group(P<0.05). Conclusion: The morphology of GPG in young Han population is diverse, mainly in depressed type and deep groove with crest type. And the gender and the palatal vault morphology are related to the relative position of GPG. CBCT assessment can be an efficient and accurate used in treatment design and reduce the postoperative complications.
