Root resorption caused by osteoma growth
introduction. Osteoma is a benign and asymptomatic neoplasm, consisting of well-differentiated mature bone. The solitary osteoma may be classified as: peripheral when arising from the periosteum, central when arising from the endosteum and extraskeletal when arising in soft tissue. The etiology of osteoma is still unclear. Some reported cas- es did have a clear history of trauma; however, this was not the case in the majority of cases. Whereas peripheral osteomas are fairly easy to diagnose, central osteomas pose a more challenging diagnostic problem and need to be differentiated from other similar lesions of the jaws, such as central ossifying fibroma, osteoblastoma, cementoblas- toma and …
Influence of operator’s experience on the shaping and centering ability of WaveOne single-file system
Aim. The aim of this study was to assess the influence of operator experience on the centering ability of WaveOne reciprocating system on S-shape simulated root canals. Methods. Forty S-shaped canals in resin blocks were assigned in two groups (n=20 for each group). Groups 1 was shaped by an expert operator, postgraduate in endodontics with more of ten years experience, while a not expert operator, a student in the last year of study, with poor endodontic experience performed shaping in Groups 2. A first survey of canals has been made with K-file 10 to assess the working length (WL), after that the glide path was achieved with PathFile 1, 2, and 3 (Dentsply Maillefer) at the WL. Subsequentl…
