Intra‐coronal resorption of unerupted molars

Abstract

Abstract— Histological and clinical evidence exists to show that external coronal resorption of unerupted molars does not extend to the pulp chamber. This paper recommends surgical exposure and restoration of these teeth before progression of the resorptive process weakens the coronal tissue to such an extent that a satisfactory restoration is difficult to achieve. Failure to eliminate the defect before eruption may result in microbial contamination, rapid destruction of the underlying dentine, pulpal and periapical pathosis and possibly loss of the tooth.

Evaluation of pre‐eruptive intracoronal resorption on cone‐beam computed tomography: A retrospective study

“…In the present study, all the cases of intracoronal resorption were located just beneath the dentinoenamel junction, as reported in previous studies (Grundy et al ., ; Seow et al ., ; Hata et al ., ; Özden and Acikgoz, ; Al‐Batayneh et al, ; Uzun et al ., ). Al‐Batayneh et al .…”

Diagnosis and Management of Hidden Caries in a Primary Molar Tooth

“…2-478 Although the etiology and factors associated with the initiation of resorption remain unknown, resorptive cells originating from the surrounding bone are thought to enter the dentin through a break in the dental follicle and enamel or cementum. 39 …”

“…Usually, the occlusal enamel surface is intact (Johnson & Harkness, 1997;Kupietzky, 1999;Seow, 1998;Singer & others, 1991;Wood & Crozier, 1985), with a chalky, grayish, dry, flaky dentin that has a different consistency from caries-induced demineralized dentin (Kunz, 1997;Seow, 1998). Histological examination has shown resorption (Grundy, Pyle & Adkins, 1984;Rankow, Croll & Miller, 1986) and scalloping of the enamel at the DEJ, suggesting osteoclastic activity (Seow, 1998;Singer & others, 1991). Johnson and Harkness (1997) performed a histological study of a pre-eruptive intracoronal resorption lesion found in a pre-molar extracted for orthodontic therapy.…”
