_Case report Our office received a frantic phone call from the mother of one of our 12-year-old patients, who stated that her daughter fell while in P.E. class and broke a front tooth. We advised her to bring her daughter to the office as soon as possi- ble. Immediately after her arrival, a periapical ra- diograph of tooth 21 and extraoral photographs were obtained (Fig. 1). Upon clinical examination and review of the digital radiograph, I saw tooth 21 was horizontally fractured at the middle third. Therewasnopulpexposureevident,butthetooth did have a pinkish tint on the lingual. No mobility was noted and no periapical changes or root fractures were obvious at this time. The new American Association of Endodontists guidelines recommend taking one occlusal and two periapi- calradiographswithdifferentlateralangulations for all dental injuries, including crown fractures. If cone beam-computed tomography (CBCT) is available, it should be considered to reveal the extension and direction of the fracture.1 Dr Edward Mills, in his presentation on Site Development and Implant Protocol Based on 22 I I industry report _ use of CBCT and CAD/CAM cone beam4_2014 CBCT and CAD/CAM allow for one-day restoration of tooth 21 Author_Dr Robert Pauley, USA Fig. 4Fig. 3 Fig. 1 Fig. 2 CBE0414_22-24_Pauley 28.11.14 11:37 Seite 1 CBE0414_22-24_Pauley 28.11.1411:37 Seite 1
