Mini-invasive nonsurgical treatment of class 4 invasive cervical resorption: a case series

Invasive Cervical Resorption (ICR) is a pathological process that can lead to a progressive tooth destruction over time, as dentin is gradually replaced by granulomatous tissue. Unfortunately ICR is difficult to diagnose because it is often asymptomatic and can easily be mistaken for a carious lesion, especially in the early stages. According to the existing literature, class IV ICR treatment shows a success rate of 12.5% when the lesion affects more than one third of the root. In this paper we describe the conservative, nonsurgical approach we adopted in treating 5 cases of class IV ICR with the help of cone-beam computed tomography and operating microscope. Resorptions were filled with MTA in three cases and with Biodentine in two cases. The follow-up period ranged from 3 months to 2 years. All patients were found to be asymptomatic and check-up radiographic examinations did not show any signs of ICR relapse
