ABSTRACT
@#Tooth absorption can be divided into physiological absorption and pathological absorption. Root absorption of mature deciduous teeth is physiological absorption. Pathological absorption includes internal absorption and external absorption. Internal absorption, also known as intramedullary absorption, includes inflammatory absorption and alternative absorption. External tooth absorption originates from the outer surface of the root or the neck of the tooth and can be divided into inflammatory absorption, alternative absorption, pressure resorption and invasive cervical resorption. Invasive cervical resorption (ICR) is pathological damage caused by many factors, which usually begins in the cemento-enamel junction and extends peripherally or horizontally in the dentin. It hardly invades the pulp. Orthodontic devices, trauma, bleaching, systemic diseases, and the use of certain medications can all lead to invasive cervical resorption. The clinical manifestations of ICR are usually asymptomatic or not obvious, and most of which are found in imaging examinations. Because caries and internal absorption are often misdiagnosed through plain apical radiography, cone beam computed tomography (CBCT) can help to better understand the situation of invasive cervical resorption. Because the pathogenesis and etiology of invasive cervical resorption are not fully understood, clinical negligence and inadequate treatment of invasive cervical resorption can even cause unnecessary tooth loss. This article reviews the latest research progress on the histopathologic features, pathogenic mechanism, susceptibility factors, diagnosis and treatment of ICR, with special emphasis on susceptibility factors and their mechanisms.
ABSTRACT
Introduction: This is a case report showing interdisciplinary management of a tooth with external and cervical root resorptionusing mineral trioxide aggregate (MTA).Case Report: A 35-year-old female with a complaint of pain in upper jaw with a history road traffic accident 8 year back.Non-surgical root canal therapy was performed with the use of calcium hydroxide and triple antibiotic paste as intracanalmedicament. About 2% chlorhexidine solution was used as the final irrigant. MTA obturation was done in both central incisors;external cervical resorption in the left central incisor was repaired by reflecting the mucoperiosteal flap and sealing with MTA:The 3-month follow-up of the present case shows satisfactory results both clinically and radiographically.Conclusion: Resorption cases has to be ruled out radiographically and clinically for successful management of these cases.Non-surgical and surgical treatment has been done hand in hand for management of this case.
