In the treatment of crown fractures, adhesive fragment reattachment provides a good alternative to other restorative techniques, offering several advantages. The present paper reports a case in which the treatment of a cervical crown fracture was accomplished by reattaching the tooth fragment with a flowable resin composite. Orthodontic root extrusion was performed with a modified Hawley appliance prior to fragment reattachment. The clinical and radiographic results after 2.5 years were successful.

Objective: In this study, left atrial appendage (LAA) flow velocities of dipper and nondipper hypertensive patients were compared with normal subjects., Methods: Twenty-three patients with nondipper hypertension (NDH), 25 patients with dipper hypertension (DH), and 25 control subjects with comparable age, gender, and body mass indices were enrolled in the study. A detailed history, physical examination, and routine laboratory tests were obtained on all participants. Standard transthoracic echocardiographic examinations were performed on each subject. In addition, LAAs of all patients were visualized using transesophageal echocardiography. LAA filling and ejection velocities were measured using pulsed-wave Doppler with the sample volume placed in proximal third of the LAA. The mean LAA ejection velocity in patients with NDH (47.7 + 13.0 cm/sec) was found to be significantly lower relative to the DH (66.3 + 12.9 cm/sec) and the control group (81.7 + 8.0 cm/sec) (P < 0.001). The mean LAA filling velocity in patients with NDH (41.7 + 14.7 cm/sec) was also significantly lower relative to those observed in the DH 58.8 + 9.2 cm/sec) and the control group (67.2 + 7.9 cm/sec) (P<0.001)., Conclusion: In NDH patients, LAA filling and ejection flow rates are decreased relative to DH patients and the control group. For patients with NDH detected using ambulatory blood pressure monitoring, more aggressive treatment approach should be considered. Maintenance of LAA function may prevent potential complications secondary to left atrial appendage dysfunction., (© 2012, Wiley Periodicals, Inc.)
