Association between periodontal status and degree of maxilla
It is well known that periodontitis can stimulate the thickening of the maxillary sinus mucosa. The objectives of this study were to investigate the effect of the periodontal status of maxillary molars on the degree of maxillary sinus mucosal thickening (maxMT).

Retrospective analysis of cone-beam computed tomographic (CBCT) images of 203 periodontitis cases with maxMT. Parameters related to periodontitis in maxillary molars were measured and recorded on CBCT images. The dimension and length of the maxMT were also recorded.

The factors affecting the degree of maxMT were mainly the amount of alveolar bone loss (ABL) and the minimum residual alveolar bone height (miniRABH). Compared to mild ABL, severe and moderate ABL were more likely to display severe maxMT. And the lower the miniRABH, the more severe the maxMT.

In particular, the severity of the periodontal status of maxillary molars can influence the degree of maxMT.
