Postępowanie w przypadkach resorpcji wewnętrznej korzenia w zębach stałych
The development of complete pulp necrosis stops the growth of the resorption because the resorbing cells are cut off from the blood supply and nutriments if the pulp chamber is sealed.
Intraoral X-ray of IRR is characterized by the radiographic appearance of an oval shape enlargement within the pulp chamber or the root canal. However the early diagnosis of the IRR is difficult by examination of a conventional X-ray. If IRR is suspected, several shots under different angles of incidence are recommended. But an accurate diagnosis is essential for an appropriate treatment plan to be devised. CBCT has been successfully used to evaluate the true nature and severity of resorption lesions in isolated case reports indicating that the clinician could more confidently diagnose and manage the defect. ROC Az values of a study comparing the accuracy of diagnosis of intraoral radiographs and the CBCT, respectively, amounted to 0.78 and 1.00, indicating the superior accuracy of CBCT [18].
The use of CBCT provides a 3-dimensional appreciation of the resorption lesion with axial, coronal, parasagittal views of the anatomy. In the serial of cross-sectional views, the size and the location of the resorption are clearly determined with high sensitivity and an excellent specificity. CBCT has a high accuracy in detecting root lesions at the earliest stages [5].
Sometimes, the resorption area is filled with a deposition of metaplastic hard tissue that [...]
