Abstract:
A case is described of a 13-year-old boy who presented with infra-occluded primary molars in three quadrants. Creation of space allowed the second premolars in two quadrants to erupt spontaneously. The first premolar in the remaining quadrant did not erupt spontaneously, failing to reach occlusal contact despite orthodontic traction. CPD/Clinical Relevance: This case demonstrates apparent intermittent ankylosis of a maxillary first premolar.

Abstract:
In dental textbooks, the mandibular premolar occlusal morphology has been described as having a predominantly “U-shaped” central groove on the first premolar and a “Y-shaped” central groove on the second premolar. In this study, we examined students (n = 400) of Isfahan high schools (Iran) and first and second premolars were examined bilaterally. Morphological features of the crown, number, height and position of cusps, central grooves shape and sex of the teethwere recorded. For the mandibular first premolars, 21.5% of students exhibited H-shape grooves bilaterally; 70.0% had bilateral U-shap

Introduction: Mandibular premolars are considered an enigma in dentistry because of their variability in anatomical and morphological features making it difficult to treat endodontically. This study was conducted to determine the root and canal morphology of mandibular premolars in the Nepalese population by using cone beam computed tomography imaging. Methods: One hundred and thirty-four cone beam computed tomography images of the Nepalese population were collected by convenience sampling method from April 1 to August 31, 2022 in Bir Hospital, Kathmandu, Nepal.
