INVAZIVE CERVICAL RESORPTION: TWO CASE REPORTS

Invasive cervical resorption: two case reports Root resorption is the loss of hard dental tissue (ie, cementum and dentin) as a result of odontoclastic action. It might be classified by its location in relation to the root surface, ie, internal or external resorption. External root resorption can be further classified into surface resorption, external inflammatory resorption, external replacement resorption, extern al cervical resorption and trancient apical breakdown. One of the least understood type of external resorption is external cervical resorption (ECR). This form of external resorption has been described at length by Heithersay, who preferred the term invasive cervical resorption (ICR), which describes its invasive and aggresive nature. An early diagnosis is desirable to avoid the gross tooth destruction that is a feature of advanced lesions. It is defined as a localized resorptive process that commences on the surface of the root below the epitelial attachment and the coronal aspect of the supporting alveoler process, namely the zone of connective tissue attachment. It can be present anywhere in the root. This article describes two different invasive cervical resorption cases which had difference according to the stage of the lesions and their treatments.
