AI Article Synopsis
Article Abstract
This report describes the treatment of a 13-year-old girl with unerupted maxillary permanent canines. It illustrates how recognizing an unexpected problem influenced the decision-making process. Despite 6 months of closed-eruption traction, the left canine had not erupted. However, the neighboring teeth were intruded, suggesting a diagnosis of canine ankylosis. When the site was surgically reopened, the wire chain used for the orthodontic traction appeared to be osseointegrated. It was renewed, and traction was applied for another 16 months, and the tooth was successfully brought into the arch. Bone tissue passing through the chain might have prevented forced eruption. In young patients with unerupted maxillary permanent canines, failure of closed traction can be attributed to ankylosis, and this accounts for tooth extraction as the treatment of choice. However, this clinical report suggests that additional measures might be warranted before the definitive diagnosis of ankylosis can be made and the tooth extracted.

Aim: Pre-eruptive intracoronal resorption (PIER) defects constitute an important part of anomalies associated with unerupted teeth. However, these defects are usually overlooked by clinicians whilst interpreting radiographs. This systematic review was thus orchestrated to find the global prevalence of PEIR.

Introduction: Accuracy and user experience of dental diagnosis for a patient with cleidocranial dysplasia (CCD) using immersive virtual reality (VR) and cone-beam computed tomography multiplanar reconstruction methods were evaluated.
Methods: Dental students (n = 40) were randomly assigned to VR or MP groups. VR participants manipulated and visualized the rendered 3-dimensional model using VR hardware and software.

Odontoma is an occasionally encountered condition that disturbs the eruption of adjacent teeth. Few reports have described multiple odontomas occurring at two adjacent sites, resulting in eruption disturbances of both primary and permanent teeth. An 8-year 2-month-old boy was referred to our hospital.

Class III malocclusion presents many challenges due to its varying elements of imbalance in skeletal, dental, and soft tissues. This necessitates a comprehensive treatment plan, including growth modification during the pre-pubertal growth phase, and long-term retention to reduce the chances of orthognathic surgery later. The components of Class III malocclusion include maxillary retrognathism, mandibular prognathism, or, in some cases, a combination of both.

Objectives: Accurate estimation of unerupted permanent canines and premolars is a crucial step for effective orthodontic treatment planning during mixed dentition. This study aimed to evaluate the validity of Moyers' charts and the Tanaka-Johnston equation in predicting tooth sizes in a sample of the Madina population in Saudi Arabia and propose a new regression equation.
Methods: Dental casts from 219 subjects (113 males and 106 females) were analyzed.
