Abstract: Objective: To analyze the correlation between Schneidirian membrane thickness and periodontal tissue characteristics through CBCT images. Methods: Fifty-five participants who met the inclusion criteria were included in the study to measure the width of the labial keratinized gingiva of the upper anterior teeth. CBCT was conducted to radiograph the distance between cemento-enamel junction and bone crest of the upper anterior teeth, the gingival thickness, and the thickness of the schneiderian membrane, with aim to analyze the correlation between the thickness of mucous membrane of maxillary sinus and the characteristics of periodontal tissue. Results: The correlation coefficient of Person-related analysis between gingival thickness and Schneiderian membrane thickness was 0.275, indicating a weak positive correlation. The correlation coefficient between gingival thickness to keratinized gingival width was 0.662, suggesting a correlation between them. There was no significant correlation between the rest of indicators. The correlation between Schneiderian membrane thickness and gingival thickness was conducted with univariate and multivariate linear regression analysis and the regression coefficients were 0.324 and 0.337 (P<0.05). Conclusion: There may be some correlation between the gingival thickness and the thickness of the maxillary sinus mucosa, however, further research is required to confirm this.

Key words: cone-beam computed tomography, Schneiderian membrane thickness, gingival thickness, width of keratinized gingiva, the distance between cemento-enamel junction and bone crest
