Abstract

Introduction: Evidence suggests that periodontal disease can lead to inflammation and degeneration within dental pulp, highlighting the need for dental professionals to understand this association better.

Objective: The objective for this study was to establish a correlation between pulp volume and periodontal disease using Cone-Beam Computed Tomography (CBCT) imaging.

Methods: A cross-sectional study design was employed for the collected data from 148 patients aged 39.51 years using dental images obtained by CBCT and analyzed by medical software to create three-dimensional (3D) images. Pulp-volume analysis was performed using Amira software and measurements were derived using bio-models generated from CBCT images. Obtained data was analyzed using SPSS-27 statistical software.

Results: The mean pulp volume between healthy and teeth with periodontitis showed certain differences. The mean low and largest pulp volumes of 9.15 ± 3.3 mm³ and 15.24 ± 4.2 mm³ were observed involving teeth # 41 and teeth # 13, respectively. Furthermore, a higher mean of pulp volume was observed in healthy teeth than in periodontitis-diagnosed teeth except for teeth # 33 and 43. The significant difference (p < 0.05) was easily detected involving teeth # 22, 23, 11, and 13. However, the lowest difference, with non-significant difference (p > 0.05), involving teeth # 43, 31, and 33 was observed.

Discussion: The study's findings underscore a significant correlation between periodontitis and reduced pulp volume, suggesting that periodontal inflammation may influence pupal remodeling.

使用CBCT评估牙周炎患者的牙髓变化：体积分析。

有证据表明，牙周病可导致牙髓内的炎症和变性，这突出了牙科专业人员更好地了解这种联系的必要性。目的：本研究的目的是利用锥形束计算机断层扫描（CBCT）成像建立牙髓体积与牙周病之间的关系。方法：采用横断面研究设计，收集148例年龄39.51岁患者的数据，利用CBCT获得的牙齿图像，通过医学软件进行分析，生成三维图像。使用Amira软件进行纸浆体积分析，并使用CBCT图像生成的生物模型进行测量。所得数据采用SPSS-27统计软件进行分析。结果：正常牙与牙周炎牙的平均牙髓体积有一定差异。41号牙和13号牙的平均牙髓体积最小（9.15±3.3 mm3），最大（15.24±4.2 mm3）。此外，除33号和43号牙齿外，健康牙齿的平均牙髓体积高于诊断为牙周炎的牙齿。在第43、31、33牙组中，差异有统计学意义（p < 0.05）。讨论：研究结果强调了牙周炎和牙髓体积减少之间的显著相关性，表明牙周炎症可能影响牙髓重塑。
