- 1What are the subtypes of internal root resorption (IRR)? Is IRR a common or rare occurrence? How is IRR characterized in terms of internal structural changes? Is IRR usually symptomatic or asymptomatic? Which condition can IRR be easily confused with? What aids in identifying IRR on intraoral radiographs? What imaging technique is helpful in diagnosing the location and size of IRR? What percentage of IRR lesions were detected by CBCT scans compared to conventional radiographs in a study? What type of imaging performed better in detecting simulated small internal resorptive lesions? How many subtypes of external root resorption (ERR) are there? Does ERR progress rapidly or slowly? What are the recommended guidelines for minimizing radiation dose in young patients during radiographic examinations?Internal inflammatory or internal replacement resorption.
Relatively rare.
Internal structural changes in the tooth with varied features such as smooth or irregular borders and radiodensity of uniform or mixed attenuation.
Usually asymptomatic.
External cervical resorption (ECR).
Parallax intraoral radiographs.
Cone-beam computed tomography (CBCT).
100% of the lesions were shown on CBCT scans, while conventional radiographs detected 52.1% of lesions between 1 and 4 mm.
High-resolution CBCT imaging performed better than low-resolution CBCT imaging.
Four subtypes: external surface resorption, external inflammatory resorption, external replacement resorption, and external cervical resorption (ECR).
ERR may progress rapidly.
Select radiographs based on individual needs, use the fastest image receptor possible, collimate the x-ray beam, use thyroid collars, reduce exposure according to the child's size, use CBCT only when necessary and not as a screening tool. - 2—
