Abstract

Introduction

This study aimed to determine the correlation between proximal caries and the extent and site of pulp canal obliteration (PCO) in cone-beam computed tomographic (CBCT) scans of mandibular molar teeth.

Methods

A total of 1491 CBCT scans of patients 18–49 years of age were selected from the database (2002–2022). From them, 328 teeth with proximal caries and satisfying inclusion criteria were evaluated by 2 calibrated evaluators. PCO was observed in the sagittal and coronal planes. PCO and proximal caries were compared concerning different age groups, sexes, and sites using an independent sample t test.

Results

The prevalence of PCO among patients with proximal caries is 47%. In mesial proximal caries, the extent of PCO is significantly greater in the distal root canal (73.4%), whereas in distal proximal caries, PCO is more often found in the mesial canal (77.3%). The mean extent of intraradicular calcification was higher in the distal canal (P < .001). Moreover, mesial proximal caries showed a greater extent of intraradicular obliteration (P < .001). The probability of developing PCO was significantly higher in females (P = .003).

Conclusions

Within the limitations of this study, it can be concluded that the extent of calcification is more common on the opposite side of the location of the proximal caries. Moreover, such intraradicular calcification is greater in a distal canal compared to a mesial canal. Sex plays a significant role in the calcification process, showing higher predilection in females compared to males.

基于 CBCT 扫描的龋病位置与牙髓腔阻塞相关性评估：辅助治疗规划。

研究目的本研究旨在确定下颌磨牙 CBCT 扫描中近端龋（PC）与牙髓管阻塞（PCO）的程度和部位之间的相关性：从数据库（2002 年至 2022 年）中选取了 1491 例 18-49 岁患者的 CBCT 扫描结果。两名经过校准的评估员对其中 328 颗符合纳入标准的 PC 牙进行了评估。在矢状面和冠状面上观察 PCO。采用独立样本 t 检验比较了不同年龄组、性别和部位的 PCO 和 PC：结果：PC 患者的 PCO 患病率为 47%。在中线型 PC 中，远端根管的 PCO 程度明显更高（73.4%）；而在远端型 PC 中，中线根管的 PCO 程度更高（77.3%）。根管内钙化的平均程度在远端根管较高（p结论：在本研究的局限性范围内，可以得出结论：PC位置相反一侧的钙化程度更常见。此外，与中轴管相比，远端管内的钙化程度更高。性别在钙化过程中起着重要作用，女性比男性更容易发生钙化：临床相关性：了解 PC 与 PCO 之间的相关性有助于减少牙髓治疗过程中的错误，从而改善患者的治疗效果。

期刊介绍： The Journal of Endodontics, the official journal of the American Association of Endodontists, publishes scientific articles, case reports and comparison studies evaluating materials and methods of pulp conservation and endodontic treatment. Endodontists and general dentists can learn about new concepts in root canal treatment and the latest advances in techniques and instrumentation in the one journal that helps them keep pace with rapid changes in this field.
