[Show abstract][Hide abstract] ABSTRACT: This study compared the dental curricula at dental schools in China and Japan. A survey was conducted in representative dental schools in China and Japan. It was found that, in China and Japan where dental schools recruit students directly from high schools, more attention is paid to introduction of early professional education. Most dental schools in Japan arrange dental subjects for their students from the first through the fourth years, while in China, only a few dental schools take this path although many of them are currently making changes. It was also discovered that, in both countries, an increasing number of dental schools assign a specific dental subject to the same period with its relevant bioscience or biomedical counterparts, which makes it possible for them to enhance each other reciprocally in a positive way for students and consequently help dental students master the related topics.

[Show abstract][Hide abstract] ABSTRACT: This case series describes observations of 12 patients who developed horizontal root fractures in non-endodontically treated teeth. Using clinical and radiographic examination, horizontal fractures were observed in eight maxillary first molars, one maxillary second molar, one mandibular first premolar and four mandibular second premolars. A total of 12 teeth had clinically intact crowns and 2 had carious. Eight fractures of maxillary molars occurred in the palatal roots, while one fracture was observed in the distobuccal root. Eleven patients experienced pain from the affected teeth during mastication. Within the limits of this case series, it was concluded that these fractures were related to; root morphology, damaging masticatory habits and excessive occlusal forces.
