Abstract

Background: Root canal therapy in primary teeth is exceedingly complex due to the unique internal geometry of the pulp cavity.

Aim: The purpose of this study was to evaluate variations in primary teeth root canal morphology and applicability of the Ahmed et al. (Int Endod J, 50, 2017, 761) alphanumeric system for classifying them.

Design: A retrospective analysis of 2024 primary teeth from an existing CBCT database was performed for assessing variations in root canal morphology. Descriptive statistics and the chi-squared test were used for data analysis.

Results: The maxillary canines exhibited splitting levels of 5.9% (right) and 6.6% (left), and merging levels of 1% (both sides); maxillary lateral incisors showed splitting levels of 2.6% (right) and 0.8% (left), with no merging observed; mandibular second molars had splitting levels of 1.5% (right) and 0.8% (left), with no merging observed; and mandibular lateral incisors exhibited a merging level of 0.9% (right), with no splitting observed.

Conclusion: This study provides new insights into the variations in root canal morphology of primary teeth, particularly highlighting the variations found in primary canines. The Ahmed et al. (Int Endod J, 50, 2017, 761) classification system was found to be a useful tool for categorizing these variations.

利用锥形束计算机断层扫描对基牙根管形态进行三维评估。

背景：目的：本研究旨在评估基牙根管形态的变化以及Ahmed等人（Int Endod J, 50, 2017, 761）的字母数字系统对其分类的适用性：对现有 CBCT 数据库中的 2024 颗基牙进行了回顾性分析，以评估根管形态的变化。数据分析采用了描述性统计和卡方检验：结果：上颌犬齿的分叉率为 5.9%（右侧）和 6.6%（左侧），合并率为 1%（两侧）；上颌侧切牙的分叉率为 2.6%（右侧）和 0.8%（左侧），未观察到合并现象；下颌第二磨牙的分叉率为 1.5%（右侧）和 0.8%（左侧），未观察到合并现象；下颌侧切牙的合并率为 0.9%（右侧），未观察到分叉现象：这项研究为我们提供了关于基牙根管形态变化的新见解，尤其突出了基牙根管形态的变化。研究发现，Ahmed 等人（Int Endod J，50，2017，761）的分类系统是对这些变异进行分类的有用工具。

期刊介绍： The International Journal of Paediatric Dentistry was formed in 1991 by the merger of the Journals of the International Association of Paediatric Dentistry and the British Society of Paediatric Dentistry and is published bi-monthly. It has true international scope and aims to promote the highest standard of education, practice and research in paediatric dentistry world-wide. International Journal of Paediatric Dentistry publishes papers on all aspects of paediatric dentistry including: growth and development, behaviour management, diagnosis, prevention, restorative treatment and issue relating to medically compromised children or those with disabilities. This peer-reviewed journal features scientific articles, reviews, case reports, clinical techniques, short communications and abstracts of current paediatric dental research. Analytical studies with a scientific novelty value are preferred to descriptive studies. Case reports illustrating unusual conditions and clinically relevant observations are acceptable but must be of sufficiently high quality to be considered for publication; particularly the illustrative material must be of the highest quality.
