introduction

Dilaceration is a term used to describe the abnormal curvature or angulation of the root or crown of a tooth. This dental anomaly can pose significant challenges in endodontic treatment due to the complex anatomy and potential difficulties in instrumenting and obturating the root canal system. The successful management of teeth with dilacerations requires a thorough understanding of the etiology, clinical assessment, and appropriate treatment strategies. In this article, we will explore the various aspects of endodontic management of teeth with dilacerations.

The etiology of dilacerations can be attributed to several factors, including trauma, genetic predisposition, and developmental disturbances. Traumatic injuries during tooth formation can result in deviations in the root or crown morphology, leading to dilacerations. Genetic factors such as hereditary anomalies and syndromes can also contribute to the development of dilacerated teeth. Additionally, disturbances in tooth development, such as localized infection or inflammation, can lead to alterations in root or crown shape.

The clinical assessment of teeth with dilacerations plays a crucial role in determining the appropriate treatment approach. Radiographic evaluation, including periapical and panoramic radiographs, is essential for visualizing the extent and severity of the dilaceration. Cone-beam computed tomography (CBCT) imaging can provide detailed three-dimensional information about the tooth’s anatomy, facilitating accurate diagnosis and treatment planning. Clinical examination should involve assessing the tooth’s mobility, vitality, and periodontal status to ensure a comprehensive evaluation.

The management of teeth with dilacerations requires a multidisciplinary approach involving endodontic, restorative, and orthodontic considerations. The primary objective of endodontic treatment in such cases is to achieve thorough cleaning, shaping, and disinfection of the root canal system. However, due to the complex anatomy associated with dilacerations, traditional endodontic instruments may not adequately negotiate the curved canals. Therefore, the utilization of specialized instruments, such as rotary or reciprocating files with greater flexibility and resistance to fracture, is often necessary.

Furthermore, the use of magnification aids, such as dental operating microscopes, enhances visualization and improves the precision of instrumentation in dilacerated teeth. The incorporation of ultrasonic instrumentation can also aid in negotiating the intricate root canal anatomy and removal of any calcified or obstructing structures. The root canal should be meticulously cleaned and shaped to facilitate effective irrigation and disinfection, reducing the risk of persistent infection.

Obturation of the root canal system in dilacerated teeth presents unique challenges. The irregular root canal anatomy may require the use of alternative obturation techniques, such as warm vertical compaction or thermoplasticized gutta-percha, to ensure optimal adaptation of the filling material. Additionally, the clinician must consider the potential for future restoration and potential orthodontic requirements when determining the appropriate obturation technique.

Post-endodontic restoration is a crucial aspect of managing dilacerated teeth. The choice of coronal restoration should provide adequate structural support and protect against potential fractures. In some cases, the placement of a custom-made post and core restoration may be necessary to ensure long-term stability. Collaboration with a restorative dentist or prosthodontist is often beneficial in achieving a successful outcome.

In conclusion, the endodontic management of teeth with dilacerations requires a comprehensive understanding of the etiology, careful clinical assessment, and appropriate treatment strategies. The use of advanced imaging techniques, specialized instruments, and magnification aids can enhance the clinician’s ability to navigate the intricate root canal anatomy. Successful endodontic treatment in dilacerated teeth relies on meticulous cleaning, shaping, and obturation of the root canal system, followed by appropriate post-endodontic restoration. By employing a multidisciplinary approach and tailoring the treatment plan to each patient’s unique circumstances, clinicians can achieve favorable outcomes in managing teeth with dilacerations.

Etiology and Classification of Dilacerations

Dilacerations of teeth can have various etiological factors and can be classified based on the location and severity of the curvature.
