了解牙根尖与上颌窦下壁之间的关系对于诊断和治疗上颌窦病变以及辅助牙种植至关重要。因此，确定根尖和窦下壁之间的接近度，并明确窦下壁的皮质厚度，对于确定上颌窦内扩散性牙齿感染的地形图至关重要。因此，了解牙根尖和上颌窦下壁之间的地形对于诊断和计划牙种植、牙髓手术和正畸治疗非常重要。本研究旨在阐明上颌窦的形态和临床特征，特别是韩国人上颌窦的下壁，并确定上颌窦下壁与上颌牙根之间的关系。在这项研究中使用了24侧的上颌骨的半切韩国人的头。所有标本均进行脱钙和冠状切片。在切片标本上，使用图像分析系统测量了21个项目。测量各根尖与上颌窦下壁的距离。根尖至上颌窦下壁的距离以第二磨牙区最短，第一前磨牙区最长。上颌窦下壁皮质板厚度在第一前磨牙区最薄，在第二前磨牙区最厚。上颌磨牙下壁与牙根的垂直关系可分为五种类型。Ⅰ型（上颌窦下壁位于颊、舌牙根尖连接平面以上）占优势（第一磨牙区54.5%，第二磨牙区52.4%）。上颌窦下壁与根尖的水平关系可分为三种类型。第二型（上颌窦下壁的牙槽窝位于颊根和舌根之间）最常见（80%在第一磨牙和第二磨牙区）。本研究揭示了上颌窦的解剖学特征，并确定了上颌窦与周围结构的关系。这些发现可能对患者的临床管理产生影响。
Knowledge of the relationship between the root apex and the inferior wall of the maxillary sinus are crucial for diagnosing and treating a sinus pathosis as well as in assisting in dental implantation. Therefore, identifying the proximity between the root apex and the inferior wall of the sinus and clarifying the cortical thickness of the inferior wall of the sinus is essential for determining the topography of a spreading dental infection into the maxillary sinus. Accordingly, knowledge of the topography between the root apex and the inferior wall of maxillary sinus is important for diagnosing and planning dental implantation, endodontic procedures, and orthodontic treatment. This study was undertaken to clarify the morphological and clinical characteristics of the maxillary sinus, particularly the inferior wall of the sinus in Koreans, and to identify the relationship between the inferior wall of the maxillary sinus and the roots of the maxillary teeth. Twenty-four sides of the maxillae of hemi-sectioned Korean heads were used in this study. All specimens were decalcificated and sectioned coronally. On the sectioned specimens, 21 items were measured using an image analyzing system. The distances between the each root apex and the inferior wall of the maxillary sinus were measured. The distance from the root apex to the inferior wall of the sinus was the shortest in the second molar area and the longest in the first premolar area. The thickness of the cortical plate of the inferior wall of the maxillary sinus was thinnest in the first premolar area but it was thickest in the second premolar area. The vertical relationship between the inferior wall and the roots of the maxillary molars was classified into five types. Type I (the inferior wall of the sinus located above the level connecting the buccal and lingual root apices) dominated (54.5% in the first molar area, 52.4% in the second molar area). The horizontal relationship between the inferior wall of the sinus and the root apex was classified into three types. Type 2 (the alveolar recess of the inferior wall of then sinus was located between the buccal and lingual roots) was most common (80% in the first and second molar area). Overall this study demonstrated the many anatomical characteristics and determined the relationships between the maxillary sinus and their surrounding structures. These findings may have an impact on the clinical management of patients.
