A comparison of the use of cone-beam computed tomography and panoramic radiography in the assessment of pre-eruptive intracoronal resorption

Abstract

CBCT detected more cases of PIR than panoramic radiography. The mandibular third permanent molar was the most commonly affected tooth.

Prevalence of pre‐eruptive intracoronal radiolucencies in Thai children and adolescents: A retrospective study

“…Tooth prevalence in the present study (0.32%) was lower than that in all previous studies (0.5%‐3.47%) (Table ) . The majority of prevalence studies reported tooth prevalence of less than 1% . This low prevalence could imply that panoramic radiographs should not be prescribed to screen for PEIR, but rather, all panoramic radiographs should be routinely screened for PEIR.…”

“…The lack of a significant difference in PEIR prevalence between the sexes also corresponded to the prevalence in previous studies . The highest patient prevalence in a previous study was in a Malaysian population (27.3%), whereas most other studies reported patient prevalence to be lower than 10% (0.85%‐8.1%) (Table ) . The different prevalences between studies could be due to differences in ethnicity, the types of teeth examined, or the age range of the population (Table ).…”

“…reported that PEIR were not present in a younger age group (4‐8 years, 0%) whereas they were almost equally present in intermediate (9‐12 years, 46.2%) and adult age groups (13‐53 years, 53.8%) . Additionally, the patient prevalences in more recent studies, which had expanded population age ranges, were not much different from those in younger populations (Table ). Consequently, the wide variations in the reported patient prevalence might not be affected by differences in age range included in those studies, but rather, might result from differences in the samples in each study (ethnicity or the types of teeth examined) and different PEIR screening protocols (radiographic technique used, PEIR diagnostic criteria, diagnostic difficulties from radiographic quality, or examiner experience of this rare condition).…”

“…Pre‐eruptive intracoronal radiolucencies (PEIR) are usually incidentally detected in routine intra‐oral or extra‐oral radiographs . Most previous articles on PEIR are sporadic case reports, whereas there are limited studies explaining the prevalence and nature of the lesion . PEIR usually present as radiolucent lesions in coronal dentin adjacent to the dentino‐enamel junction on unerupted teeth .…”

“…Prevalence studies of PEIR from different countries with different populations have been published from 1999 until the time of this review . Almost all of those studies used panoramic radiographs for the screening of PEIR, except four, with two using bitewing radiographs, and other two using cone‐beam computed tomography (CBCT) . As shown in Table , these studies reported a wide range of patient prevalence, between 0.7% and 27.3%, but with a narrower range of tooth prevalence, between 0.5% and 3.47%.…”
