Background: Preeruptive caries are an abnormal, well-circumscribed, radiolucent area, occurring within the coronal dentinal tissue close to the dentinoenamel junction of unerupted teeth. OPGs are commonly taken in children for assessing the dental age and eruption sequence. It can be used as a good diagnostic source for detection of PEIR defects.
Aim: The aim of this study is to determine the prevalence of Preeruptive intracoronal dentin radiolucencies in unerupted permanent teeth from orthopantomogram.
Settings And Design: A total of 1000 standard orthopantomographs of children below 12 years of age were collected and examined.
Methodology: The OPGs were examined for PIER defects in the unerupted teeth. The prevalence of PEIR defects was assessed with respect to age, sex, tooth, and the arch involved.
Statistical Analysis: The data obtained were tabulated and analyzed. The prevalence was calculated in percentage.
Results: The participant prevalence was 13.6%. The teeth prevalence was 1.20%. The majority (38.9%) of defects were seen in the in the mandibular first premolar. Almost half of the lesions were located on the mesial side (52.3%), with a size less than one-third of dentine thickness (53%).
Conclusion: PIER defects constitutes an important part of anomalies associated with unerupted teeth and thus needs a proper understanding of its prevalence, etiology, manifestations, and complications. These defects are usually overlooked by clinicians while interpreting radiographs; however, it is of utmost importance to promptly diagnose these defects thus preventing further complications.

A dentigerous cyst (DC) is the most common developmental cystic lesion of the jaws. Histologically, these cysts derive from the odontogenic epithelium that includes the reduced enamel epithelium, epithelial cell rests of Serres, and epithelial cell rests of Malassez. Radiographically, DCs are usually presented as well-defined radiolucencies associated with the crown of an unerupted tooth at the level of the cementoenamel junction (CEJ).

Renal tubular acidosis (RTA) is a group of disorders in which there is an alteration in acid-base homeostasis because of the impairment of nephrons to excrete hydrogen ions or reabsorb bicarbonate ions, resulting in chronic metabolic acidosis. RTA is an important cause of rickets, particularly 'resistant rickets'. Dental manifestations frequently reported in patients with RTA include enamel hypoplasia and amelogenesis imperfecta, affecting permanent dentition.

Tooth impaction and eruption failure present common challenges in pediatric dentistry. We report a case of a 10-year-old boy of Indian origin presenting with a missing left mandibular primary second molar and impacted first permanent molar. Radiographic examination revealed an ankylosed primary molar obstructing the path of an unerupted premolar.

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.
