ABSTRACT
Craniosynostosis syndromes are birth defects characterized by the premature fusion of one or more cranial sutures before the completion of brain growth and development. Crouzon syndrome (CS) is the most common craniosynostosis condition. The CS manifestations result from the early fusion of superior and posterior sutures of the maxilla along the orbital wall and affect the cranial vault, base, orbital, and maxillary regions. This report presents a rare case of a 25-year-old male CS patient referred for orthodontic treatment with the chief complaint of severe irregularities in the arrangement of teeth and abnormal facial appearance. In this report, the clinical, cephalometric features, and initial orthodontic management of this patient are discussed as part of multidisciplinary management.
ABSTRACT
Objectives: The aim of this study was to evaluate the prevalence of bifid mandibular canal (BMC) using cone-beam computed tomography (CBCT) and panoramic images through meta-analysis. Methods: Databases of Scopus, PubMed, and Web of Science were searched to find the relevant studies. Studies the met the inclusion criteria were selected. Variables of prevalence, side, length and diameter of BMC and sex were assessed. Data was analyzed using STATA software version 17. Results: Of the 1164 articles initially selected, 36 were enrolled. A total of 38077 patients were considered. The overall prevalence of BMC was 18.0%. Studies that evaluated CBCT images reported higher prevalence of BMC compared to panoramic images (25.0% vs 3.0%). The prevalence of BMC was higher in men than women and slightly higher in right side than the left side of the jaw, but none of those differences were significant. Conclusion: The results have shown a total prevalence of 18.0% for BMC. Detection power of CBCT images were higher than panoramics. There was no significant relation between prevalence of BMC with sex or side of the jaw.
