Prevalence and characteristics of intracoronal resorption in unerupted teeth in the permanent dentition: a retrospective study

Abstract

Objective To determine the prevalence, types of teeth, and distribution of intracoronal resorption in permanent dentition in a large population. Methods A total of 9,570 panoramic radiographs were screened, and 2,922 unerupted teeth were examined. Results The prevalence of intracoronal dentine defects was 1.55% in subjects and 0.95% in teeth. The highest prevalence of intracoronal radiolucencies was noted in the mandibular second molar (9.5%), followed by the maxillary second premolar tooth (4.7%). To our knowledge, this is the first report of coronal radiolucency in maxillary supernumerary teeth. Of the lesions identified, 39.3% were two-thirds of the dentine thickness, and 21.4% included the enamel; 85.7% of the defects were located at the central aspect of the crown. Ectopically positioned teeth showing intracoronal resorption accounted for 14.3% of the cases. Conclusions Intracoronal resorption in an unerupted tooth occurs frequently and can be seen in more than one tooth in an individual. This condition is usually associated with not only an ectopic position but also resorption, which may be a progressive process. Dental clinicians should conduct periodic follow-ups, both clinical and radiographic, of these unerupted teeth.

Cone Beam Computed Tomographic Analysis of Pre-Eruptive Intracoronal Resorption in a Primary Tooth: A Very Rare Case

“…6 According to some studies, surgical intervention and restoration of an unerupted tooth or after eruption root canal treatment are recommended. [2][3][4][5][6] In the present case, the maxillary primary second molar tooth with PIR was extracted due to obstruction of the maxillary second premolar. The patient was then referred to an orthodontist for additional dental treatment.…”

“…[1][2] However, some studies suggested that PIR was associated with local factors, such as chronic apical inflammation and ectopic eruption, or systemic factors. [3][4] A number of case reports described this defect in permanent teeth, using panoramic or bitewing radiographs. 1-6-8 As conventional radiographs Cone Beam Computed Tomographic Analysis of Pre-Eruptive Intracoronal Resorption in a Primary Tooth: A Very Rare Case A AB BS S T TR RA AC CT T Pre-eruptive intracoronal resorption (PIR) is very rare in primary teeth, and the etiology and factors associated with the resorptive process remain unclear.…”

“…Hence, defects might be missed, especially in mixed dentition. 3 Recently, cone beam computed tomography (CBCT) has been used to evaluate the internal and external morphology of teeth. 5 CBCT offers highresolution and three-dimensional (3D) views, without superimposition, thereby overcoming the limitations of 2D imaging.…”

Pre-eruptive Intracoronal Resorption of Dentin in a Permanent Molar: Case Report

“…[8][9][10] No amelogenesis imperfecta, dentinogenesis imperfecta, hypophosphatemic rickets, or other dental or medical pathology that can affect the dental structure of teeth has been observed. 12 The aims of this report were to explain a case of PEIR, histopathologically analyze it, and provide awareness of this rare occurrence.…”

Pre-Eruptive Intracoronal Resorptions of Mandibular First Molars and Their Treatments with Laser Therapy: Two Case Reports

“…[1][2][3]13,14 Süt dişinin periapikal inflamasyonun altında gelişmekte olan daimi dişi etkileyebileceği, ancak bu teorinin literatürdeki tüm olguları, özellikle üzerlerinde süt dişi yer almayan daimi molar diş-lerin defektlerini açıklamada yetersiz kaldığı bildirilmiştir. 1,2,[15][16][17] İntrakoronal radyolüsensiler radyografta çürük benzeri görüntü verse de, çürük teşhisi konulabilmesi için histolojik değerlendirmelerin dentinal tübüllerde bakteri varlığını göstermesi gerektiği, ancak pek çok olguda birincil amaç dişin ağızda tutulması olduğundan, histolojik delilin yetersiz olduğu, bazı araştırmacılar çalışmalarında çürük ve bakteri varlığı rapor etmekle birlikte, bunların parsiyel ya da tamamen ağız florasına açıl-dığı, gömülü sürmemiş bir dişte çürük görülebile-ceğini destekleyen ya da reddeden bir kanıtın bulunmadığı bildirilmiştir. 7,13,15,18 Rezorpsiyon pek çok sürmemiş dişte görülen intrakoronal radyolüsensinin etiyolojisiyle ilgili olarak rapor edilmiştir.…”
