We would like to congratulate the authors of the article on a well-designed and meticulously executed study which investigates impacted and transmigrated mandibular canines. The paper’s material constitutes a large group of canines with the use of cone beam computed tomography (CBCT) to detect both pathological findings of the impacted canines and the influence of impacted teeth on their adjacent teeth and other anatomical structures. The results and conclusions are in most cases adequately presented; however, one explanation is missing for a single but clinically relevant issue. The authors analyze root resorption of adjacent teeth, which is caused by impacted canines, with an outstanding precision regarding diagnostic tools and interpretation. The results of the study support the previous findings published by Mazinis et al.  and many other studies which evaluated the impact of impacted canines on the adjacent teeth.
Contrary to the above, the process of resorption...
