External root resorption of permanent teeth is a multifactorial process. Several etiologic and predisposing factors have been related to external root resorption. Idiopathic external root resorption is defined as cases of external root resorption without a distinct etiologic factor. This article presents an extensive idiopathic external root resorption of maxillary first molar with irreversible...

conclusion considering the similar diagnostic efficacy of all voxel sizes, 300 µm voxel size can be used with adequate efficacy for detection of external root resorption defects with minimal patient radiation dose and the shortest scanning time. background selecting a voxel size that yields minimal radiation dose with no significant compromise of the diagnostic accuracy of cone beam computed to...

The aim of this investigation was to compare root resorption in the same individual after application of continuous intrusive and extrusive forces. In nine patients (mean age 15.3 years), the maxillary first premolars were randomly intruded or extruded with a continuous force of 100 cN for eight weeks. Eleven maxillary first premolars from six randomly selected orthodontic patients served as co...

introduction: external root resorption is a clinical problem that often cannot be detected clinically. thus, radiography plays a crucial role in its diagnosis. however, optimal radiographic quality with minimal radiation exposure {2.1 [en] verify english word/phrase choice} is an important factor in selecting the appropriate radiographic technique. the aim of this study was the comparison of ac...

The aim of this study was to examine the potential relationship between the occurrence of orthodontic root resorption and presence of dental anomalies such as tooth agenesis and pipette-shaped roots. Dental anomalies and root resorption were assessed on dental panoramic tomographs (DPT) of 88 subjects, 27 males and 61 females, mean age 28.4 (SD = 11.3 years), selected from orthodontic patients ...

background and aims. early diagnosis of external root resorption is important for accurate treatment. the purpose of this study was to compare the efficacy of a charge-coupled device (ccd) sensor and a photostimulable phosphor (psp) plate receptor in the diagnosis of artificial external root resorption. materials and methods. in this diagnostic in-vitro study, 40 maxillary incisors were mounted...
