When restoring primary teeth, many factors, including age, compliance, caries risk level, oral hygiene/plaque control, the type of tooth, cavitation status, moisture control, retention of the restoration, aesthetics, cost and parents' motivation, should be considered. [1][2][3][4] Despite the many advances in dentistry, there remain difficulties in obtaining satisfactory results in the restoration of primary teeth with excessive tooth structure loss. 5 In these cases, full-coverage crowns are preferred for the restoration of teeth with extensive, multisurface and subgingival carious lesions, as well
re-eruptive intracoronal resorption (PEIR) is an idiopathic lesion in the crown of an unerupted tooth. 1 PEIR has been described in the literature in sporadic case reports of unerupted teeth with radiolucency in the crown. [2][3][4] In articles, this type of lesion is also called an intracoronal radiolucent lesion, pre-eruptive caries, pre-eruptive intracoronal resorptive lesion, or pre-eruptive intracoronal defect.5-7 PEIR of a tooth looks like a caries lesion. PEIRs are often found within the dentin, adjacent to the amelodentinal junction in the occlusal aspects of the crown. 8,9 These defects have been found generally in a mandibular permanent molar or a maxillary permanent molar during radiographic examination. Pre-eruptive Intracoronal Resorption of Dentin in a Permanent Molar: Case Report A AB BS S T TR RA AC CT T Pre-eruptive coronal resorption (PEIR) appears as a radiolucent lesion in the coronal dentin, under the enamel-dentin junction of unerupted teeth and as caries on radiographs. This case report represents a rare case of PEIR of a semierupted second permanent molar, which was determined by chance on a radiograph of a young patient who was refered to our clinic for the pain complaint of another tooth. Semi-erupted permanent second molar's enamel structure was sound and abnormal pink color was realized. Panoramic and periapical radiographies were examined. The lesion was removed from the tooth after gingival tissue corresponding to the occlusal surface of the tooth was cauterized under regional anesthesia. The soft tissue and enamel fragments were histopathologically examined. This case report contains the diagnosis, histopathologic analysis, management of the lesion, and discussion of the probable etiology.K Ke ey y W Wo or rd ds s: : Tooth Resorption; dentin; dentition Ö ÖZ ZE ET T Sürme öncesinde görülen koronal rezorpsiyon (SÖKR), sürmemiş dişin mine-dentin sınırının altında, koronal dentinde görülen radyolusent lezyonlardır. Radyografik muayenede çürük olarak görülmektedir. Bu olgu raporunda, başka bir dişindeki ağrı şikayeti ile kliniğimize başvuran genç bir hastada radyografik muayenede rastlanan, nadir görülen SÖKR sunulmuştur. Yarı sürmüş daimi ikinci molar dişin mine dokusu sağlam olmakla birlikte anormal pembe renk dikkat çekmiştir. Hastadan ponoramik ve periapikal radyografiler çekilerek değerlendirilmiştir. Dişin distalden oklüzal yüzeyini saran gingival doku bölgesel anestezi altında koterize edilerek kaldırılmıştır. Sağlam mine dokusunun kaldırılmasının ardından lezyon çıkartılarak histopatolojik değerlendirme için gönde-rilmiştir. Bu olgu sunumunda, vakanın teşhisi, histopatolojik analizi, lezyonun tedavisi ve olası etiyolojik faktörler anlatılmıştır.A An na ah h t ta ar r K Ke e l li i m me e l le er r: : Diş rezorpsiyonu; dentin; diş çıkarma T Tu ur rk ki iy ye e K Kl li in ni ik kl le er ri i J J D De en nt ta al l S Sc ci i C Ca as se es s 2 20 01 15 5; ;1 1( (4 4) ): :2 23 37 7--4 41 1
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
