The mechanisms of root resorptions are known, and their causes are well defined. They are clinically asymptomatic and do not induce pulp, periapical or periodontal changes; rather, they are usually consequences of these phenomena. Root resorptions are local and acquired defects, and not dental signs of systemic diseases. Root resorptions occur when structures that protect teeth from bone remodeling, particularly cementoblasts and epithelial rests of Malassez, are eliminated.
