Changes in Maxillary Sinus Mucosal Thickening following the Extraction of Teeth with Advanced Periodontal Disease: A Retrospective Study Using Cone-Beam Computed Tomography

Figure 1

Sagittal section showing changes in SL and ST before and after tooth extraction in patients with MT. (a) Before tooth extraction. (b) Four months after tooth extraction. SL is the distance from the beginning to the end of the total area of sinus mucosal thickening (that is, the distance between points A and B). ST is the distance between the sinus floor and the highest point of the mucosa in the total area exhibiting sinus mucosal thickening (that is, the distance between points C and D).
