Accelerated Tooth Movement with Orthodontic Mini-Screws.

This case report outlines the possibility of accelerated tooth movement with the combination of microosteoperforation and mini-screws. A 14-year-old male patient presented Class II malocclusion with maxillary incisor protrusion. Upper first premolars were extracted, and after leveling, accelerated canine distalization started. For pre- and postdistalization times, amount of distalization, periodontal health, and root resorption were assessed. Within the limitations of this case report, micro-osteoperforations with mini-screw have a potential for shortening the treatment time.

Facial soft tissue changes after orthodontic treatment.

OBJECTIVES: To successfully meet expectations on facial esthetics, it is important to understand normal craniofacial growth and the impact of orthodontic treatment thereon. To date, there have been few studies documenting changes in facial esthetics through photography. The objective of this study was to compare facial soft tissue esthetics before and after orthodontic treatment by means of photographic analysis. MATERIALS AND METHODS: The 45 children were divided into 3 groups according to Angle's classification: Groups I, II, and III comprised children with class I, II, and III malocclusion, respectively. Photographs were analyzed with a software. Twenty-one soft tissue landmarks were identified on profile and frontal photographs, ratios and angles were calculated. RESULTS: For group I, there was no difference between pre- and post-treatment facial analysis. For group II, there were significant changes in 5 values. The most significant changes were observed for A-N-B and Al-Me/Ch-Me. For group III, we noted significant changes for 5 values. The most significant change was observed for N-Pn-Pog. CONCLUSION: There were significant changes in facial soft tissue esthetics after orthodontic treatment for class II and III cases. Changes in A-N-B and nose tip angle (N-Pn-Cm) were observed for class II and class III subjects.

Painless aortic dissection with bilateral carotid involvement presenting with vertigo as the chief complaint.

A 63 year-old woman was admitted to the emergency department with vertigo, nausea, and vomiting. On arrival, she was fully oriented and cooperative. She denied any pain in her chest, neck, back, or abdomen. A bruit was heard on both sides of her neck. Cranial computed tomography (CT) revealed no abnormality, while thoracic CT disclosed dissection in the ascending aorta, aortic arch, and bilateral common carotid arteries. After several hours, the patient underwent vascular surgery. She had an uneventful course and was discharged without any sequelae after 10 days. Vertigo is a rare presentation of aortic dissection with carotid involvement. Elderly patients presented with vertigo and nausea/vomiting should be evaluated for the condition and carotid dissection should be ruled out. Carotid bruit may be a clue to the diagnosis.
