Traumatic injuries of teeth involve varying degrees of damage to the supporting soft tissues or the teeth itself. A very common injury to the permanent dentition affecting children and adolescents during their growing years is the anterior crown fracture. Recent developments in restorative material, placement techniques, preparation designs, and an adhesive protocol allow clinicians to predicta...
Dental trauma is more common in young patients and its sequelae may impair the establishment and accomplishment of an adequate treatment plan. This paper reports a case of complicated crown-root fracture in a young adult that was treated using adhesive tooth fragment reattachment and orthodontic root extrusion. Considering the time elapsed to follow up, the fracture extension, the amount of rem...
INTRODUCTION The aim of this retrospective study was to examine the effect of orthodontic extrusion on the pulpal vitality of maxillary incisors with a history of trauma. METHODS Pulpal condition was examined clinically (rating of crown color and sensitivity testing with a cryogenic spray) and radiologically (periapical and panoramic radiographs) after orthodontic extrusion of previously trau...
OBJECTIVES The present study was designed to test the null hypothesis that there is no difference in the fracture resistance of pulpless teeth restored with different types of post-core systems and full coverage crowns. METHODS Extracted human upper premolars were restored with a fiber post, prefabricated metallic post or cast metallic post-core. Teeth with full crown preparations without pos...
AIM The purpose of this study was to compare the fracture resistance of endodontically treated teeth restored with different post and core systems in combination with complete metal crowns in teeth with no coronal structure. METHOD AND MATERIALS Fifty extracted mandibular premolars were divided into five groups. The coronal portion of each tooth was removed at the cementoenamel junction (CEJ)...
The aim of this study was to evaluate the fracture resistance of simulated immature teeth after different intra-radicular treatments. Crowns and roots of bovine incisors were cut transversally and removed to simulate immature teeth. Root canal preparation and flaring were performed using a bur in crown-apex and apex-crown direction. The samples were distributed into 5 groups (n=10): Positive co...
