Cone beam computed tomography (CBCT) imaging techniques are the recent rage in the field of oral diagnostic imaging modality. It is noninvasive, faster and lacks anatomic superimposition. Earlier maxillary occlusal radiographs were used to assess and evaluate the mid palatal suture, but being a two dimensional imaging modality it could not assess the ossification process which takes place in multiple planes mostly due to curved nature of the palate. In this study we assessed the mid palatal suture morphology and classify them according to the variants using CBCT images.
A total of 200 CBCT scans (95 males and 105 females) were evaluated in the present study from the archives of an imaging center. As per Angelieri classification the midpalatal suture was classified into five categories (A-E) depending on the degree of ossification that had taken place. Statistical analysis was done by Chi Square test using SPSS version 23.0.
There is statistically significant difference present in the stages of maturity of mid palatal suture in various age groups with Stage B is most common in Group 1 (50%), Stage C most common in Group 2 (60%) and Group 3 (40%) and Stage E more common in Group 4 (50%).
The results of the present study showed a wide variation in the initiation time and the degree of ossification and morphology of the midpalatal suture in different age groups. Although there was an increase in the closure of the suture with aging, age is not a reliable criterion for determining the open or closed nature of the suture. This finding is important in providing an idea as to how diverse is the ossification of maxillary sutures.
锥形束计算机断层扫描（CBCT）成像技术是口腔诊断成像领域的最新热点。它是非侵入性的，更快，并且没有解剖叠加。早期的上颌咬合片用于评估和评估中隔骨缝，但作为二维成像方式，它无法评估发生在多个平面上的骨化过程，主要是由于 palate 的弯曲性质。在这项研究中，我们使用 CBCT 图像评估中隔骨缝的形态，并根据变体对其进行分类。
本研究共评估了来自成像中心档案的 200 例 CBCT 扫描（95 名男性和 105 名女性）。根据 Angelieri 分类，中隔骨缝根据已发生的骨化程度分为五类（A-E）。使用 SPSS 版本 23.0 通过卡方检验进行统计分析。
不同年龄组中隔骨缝成熟度的阶段存在统计学显著差异，其中 B 期在第 1 组（50%）中最常见，C 期在第 2 组（60%）和第 3 组（40%）中最常见，E 期在第 4 组（50%）中更常见。
本研究的结果表明，不同年龄组中隔骨缝的起始时间、骨化程度和形态存在广泛差异。尽管随着年龄的增长，骨缝的闭合程度有所增加，但年龄并不是确定骨缝开放或闭合性质的可靠标准。这一发现对于了解上颌骨缝的骨化多样性非常重要。
