Abstract：BACKGROUND:Hard palate mucosa serves as a main donor material in periodontal plastic surgery and its thickness is crucial for the surgical outcomes. OBJECTIVE: To analyze the thickness of hard palate mucosa in Han population, and analyze the consistency between cone-beam CT image analysis and trans-gingival probing method. METHODS: A total of 30 Han volunteers (300 teeth) were recruited, and the thickness of hard palate mucosa was measured using cone-beam CT image analysis or trans-gingival probing method, to analyze their consistency. RESULTS AND CONCLUSION: The two methods showed a higher consistency in the thickness of hard palate mucosa at the cuspid, first and second premolars as well as first and second molars. The thickness of the hard palate mucosa related to the distance from the gingival margin and tooth position, the thickness from the canine region to the second premolar region thickening gradually, and became the thickest at the second molar, and the thinnest at the cuspid. This study for the first time analyzed the thickness of hard palate mucosa in Chinese Han population, and confirmed there is a high consistency between cone-beam CT image analysis and trans-gingival probing method.
