Analysis of dimensions and shapes of maxillary and mandibular dental arch in Korean young adults.

Purpose: The aim of this study was to investigate dental arch dimensions and to classify arch shape in Korean young adults.

Materials And Methods: The sample included 50 Koreans with age ranging from 24 to 32 years. Maxillary and mandibular casts were fabricated using irreversible hydrocolloid and type III dental stones.

Analysis of crown size and morphology, and gingival shape in the maxillary anterior dentition in Korean young adults.

Purpose: The aim of this investigation was to analyze the dimensions of clinical crowns and to classify the crown and the gingival type in the anterior teeth in Korean young adults.

Materials And Methods: Casts were obtained from 50 subjects ranging in age from 24 to 32. Measurements of length and width were made on the casts using a pair of digital calipers on the entire dentition.

Rebleeding of Ruptured Intracranial Aneurysms in the Immediate Postoperative Period after Coil Embolization.

Objective: Early rebleeding after coil embolization of ruptured intracranial aneurysms is rare, however serious and fatal results of rebleeding have been reported. We studied the incidence and angiographic and clinical characteristics of rebleeding of ruptured aneurysms occurring in the immediate postoperative period after coil embolization.

Materials And Methods: We analyzed patients who had aneurysmal subarachnoid hemorrhage and underwent coil embolization.

Spontaneous Occluded Anterior Communicating Artery Aneurysm during Coil Embolization Treated with One Coil Insertion into Remaining Stump.

Spontaneous thrombosis of a ruptured aneurysm during coil embolization is a rare event, and some reports on recanalization of a spontaneous occluded ruptured aneurysm have been published. We report on a case of a 54-year-old male who presented with a subarachnoid hemorrhage due to rupture of a small aneurysm of the anterior communicating artery (ACoA). Cerebral angiography confirmed the presence of the ACoA aneurysm, but, during coil embolization, the aneurysm was near completely occluded with a remaining small neck.
