Invasive cervical resorption is a type of external resorption, which is generally located in the cervical region of the tooth. The resorptive process can be caused by physiological, pathological, hormonal, and trauma factors. The present study aimed to report a case of invasive cervical resorption in tooth 12 identified as an incidental finding, in which all available clinical resources were used, as well as a combined multidisciplinary treatment of endodontics, orthodontics, surgery, and prosthesis.
After completion of orthodontics, an increase in the resorptive pocket was observed Class III of Heithersay , which led to endodontic retreatment and subsequent surgical intervention to remove the granulation tissue and fill it with bioceramic material.
The preparation of the coronal remnant and fabrication of a prosthetic restoration were performed, with the aim of shielding the endodontic cavity and functionally restoring the tooth. Tooth resorption is a progressive dentin loss that can be traumatic or infectious origin related.
The literature is not conclusive regarding the etiological factor of tooth resorption; however, there are correlated factors: dental trauma, orthodontic movement or even infections of the endodontic and periodontal system, or idiopathic [1]. Orthodontically induced inflammatory root resorption OIIRR is a common phenomenon that can be triggered by an adverse effect of orthodontics; however, it usually ceases when the force is removed [1] , [2] , [3].
The force applied during orthodontic treatment induces inflammation and can be related as one of the etiological factors of root resorption. Thus, it is suggested that the applied force be in the range of 20— g tooth G1 for the desired tooth movement. This type of resorption may present as a radiolucent lateral defect or shortening of root length [2] , [3].
