Clinical technique for invasive cervical root resorption

Abstract

This clinical case report describes the diagnosis and treatment of an external invasive cervical resorption. A 17-year-old female patient had a confirmed diagnosis of invasive cervical resorption class 4 by cone beam computerized tomography. Although, there was no communication with the root canal, the invasive resorption process was extending into the cervical and middle third of the root. The treatment of the cervical resorption of the lateral incisor interrupted the resorptive process and restored the damaged root surface and the dental functions without any esthetic sequelae. Both the radiographic examination and computed tomography are imperative to reveal the extent of the defect in the differential diagnosis.

Endodontic management of a mandibular second premolar with perforating internal resorption by using MTA and cone beam computed tomography as a diagnostic aid

“…[5] However, even with the use of ultrasonic instruments, bacteria might still remain in confined areas. [7] Chemo mechanical debridement of the root canal space fails to consistently render the root canal system bacteria-free. Thus, an intracanal, antibacterial medicament should be used to improve disinfection of the inaccessible root resorption defects.…”

“…The advent of cone beam computed tomography (CBCT) has enhanced radiographic diagnosis providing greater 3D appreciation of the tooth, the resorption lesion, and the adjacent anatomy. [67] The true nature of the lesion might be assessed, including root perforations and whether the lesion is amendable to surgical or non-surgical treatment. Andearson has stated that an untreated internal resorption leads to premature loss of the tooth.…”

The effect of retreatment procedure on the pH changes at the surface of root dentin using two different calcium hydroxide pastes

“…[717] The alkaline environment created by the calcium hydroxide in the dentin may interfere with the resorptive activity of dentinoclasts that require an acidic environment to achieve mineral dissolution. [18]…”

“…[78] It is thought that absence of cemental layer following trauma may lead to the opening of dentinal tubules to the periodontal space. Therefore intra-canal medicaments could reach areas of resorption in the periodontal ligament space.…”

“…Intra-canal application of this medicament is also a well – established method for inhibition of external root resorption and stimulation of periapical healing in traumatized teeth. [ 7 8 ] It is thought that absence of cemental layer following trauma may lead to the opening of dentinal tubules to the periodontal space. Therefore intra-canal medicaments could reach areas of resorption in the periodontal ligament space.…”
