With developments in computer science and data science, the field of artificial intelligence known as machine learning entered the dental field. It has been used in endodontics, for example, to locate periapical lesions in the radiographs, Identification of the root canal morphology, detection of root fracture etc. The majority of studies employ supervised machine learning, wherein humans provide a labeled input data set for the computer to train using statistical equations, producing intricate mathematical models. Once the created model has proven to be sufficiently efficient, it is then put into use, and its performance is reviewed. Convolutional neural network (CNN) learning techniques are utilized to extract crucial data for model creation from imaging and radiography data, which make up most of the data used in endodontic research. Most research has concluded that machine learning is effective. Enhance decision-making speed while increasing operational precision. It might serve as a supplementary mechanism to improve operational efficiency.

Apical Debris Extrusion in Endodontics: Unraveling Influential Factors

Debris generated primarily during chemical-mechanical root canal preparation is composed of dentine fragments, residual dental pulp remnants, microorganisms, and irrigants. The unintended extrusion of this debris toward the periapical region gives rise to postoperative pain or flare up, which can significantly impact the patient's quality of life. Furthermore, in certain scenarios, the apical extrusion of debris can foster the development of extraradicular infections. In this review, we provide a comprehensive overview of apical debris extrusion, with a specific focus on the determinants influencing this phenomenon. Notably, the curvature of the root canal, an inherent property of the tooth itself, is a pivotal factor that exerts a discernible influence on the apical debris extrusion. Additionally, other procedural elements during root canal treatment, such as the access cavity, the working length determination, the mechanical instrumentation process, and the root canal irrigation method, play crucial roles in modulating the amount of apical debris extrusion.

This article provides an in-depth exploration of the concept of reliability, its significance, and various methods used for its assessment. Reliability is crucial in research and evaluation as it represents consistency and reproducibility in various contexts. High reliability instills confidence in the research or evaluation outcomes, advancing knowledge in several domains. Conversely, unreliable data can lead to erroneous analyses. Key aspects of reliability discussed include its definition and types. Test-retest reliability focuses on the consistent outcomes of repeated measurements over time. Inter-rater reliability examines the consistency of evaluations between different assessors of the same data, while intra-rater reliability emphasizes the consistency of a single assessor over different times. Various methods to assess reliability, such as percent agreement, Cohen’s kappa, and Intra-Class Correlation (ICC), among others, are also detailed.

Endodontic microsurgery is one approach for managing root canal treatment failures, especially when obstacles such as post and core with crown restorations are involved. However, cases with anatomical limitations, such as an exostosis impeding the surgical site, may result in more complex planning and treatment processes than usual. This case report aims to document a successful treatment procedure with an interdisciplinary approach to carry out a one-visit endodontic microsurgery concurrent with an exostosis removal in a 48-year-old Thai female patient. The patient presented with an acute apical abscess on her upper right central incisor due to a failure of the preceding primary root canal treatment. The tooth was previously restored with a post and core with crown, which remained in good condition with an intact margin. At the surgical site, a large exostosis was found to obstruct the endodontic surgical intervention. Moreover, the patient also had food impaction and cleaning difficulty in this area. As a result, the patient underwent apical surgery with the exostosis removal simultaneously. A one-year follow-up revealed that the patient had remained asymptomatic. The crown was still in good condition without any gingival recession. Furthermore, the size of the exostosis decreased, resulting in the patient’s improvement of oral hygiene care. Radiographic assessments confirmed a complete resolution of the periapical lesion.
