Odontogenic anomalies can occur as a result of conjoining defects. These include fusion, gemination and concrescence. The presence of fused teeth can lead to various clinical problems, including the aplasia of permanent successor, the supernumerary teeth and delayed eruption of permanent teeth. In general, the supernumerary teeth associated with fusion is mainly found in the maxillary anterior region. This report describes rare cases of supernumerary tooth associated with fused teeth of mandibular primary lateral incisor and canine. In the first case, fused teeth was extracted. The supernumerary teeth was erupted at canine space. The second case is still being observed. Extraction of fused teeth and observation of supernumerary teeth is planned.

An 11-year-old spayed female Maltese dog presented with mass in oral cavity. On conscious oral examination, the right maxillary canine tooth was not visible, and a lesion has been suspected of mass existed in canine tooth area. The adjacent maxillary first premolar was buried in the lesion, with a little part of the tooth exceptions. On radiographic examination, the canine tooth was buried horizontally in the lesion, and the root part was adjacent to the first premolar tooth. Extraction was performed for a treatment. When the lesion was incised, the canine tooth was horizontal with the concave surface facing the palatal, and formed double teeth by fusing with the premolar tooth at the roots parts of the teeth. This report described the double teeth in the dentigerous cyst rarely reported in dogs.

Dwelling refers to a way of being that has to do with a cautious and guarded attitude. What has to be nurtured and preserved is the dweller's relationship with the fourfold of heaven and earth, divinities and mortals. This leads to the fourfold definition that mortals dwell insofar as they save the earth, receive heaven as heaven, await the divinities as divinities, and are capable of death as death. Heidegger sees the thing as the concrescence of what he calls the fourfold of earth, sky, mortals, and divinities. For Heidegger, true being means to be open to the fourfold, to tend the fourfold in its essence. C. Norberg-Schulz takes as his starting point Heidegger's notion of the thing as that in which the fourfold is assembled. The built space must be organized in a way that concrete places are created, places that are characterized by a specific genius loci. This idea refers to life in the warm seclusion of a traditional community, but is much less applicable to the functional networks and relationships that determine life in a modem society. Cacciari thinks that what is worth questioning is in particular the condition of homelessness perceived by Heidegger, and the possible consequences of this situation for architecture. The aim of this paper is to study the meaning of dwelling through Heidegger's concept of dwelling and the interpretations of C. Norberg-Schulz and M. Cacciari about it.

In order to grasp the clear concepts and variables to treat Shanghan diseases which has complex meaning by each medical literature, several concepts and analytic method of structuralism from early to late stage encompassing Saussure and Derrida were used. Main concepts are langue and parole, signifiant and signifie, syntagme and paradigme, denotation and connotation, synchronie and diachronie, identity of structure and differance etc. and methods are substituting these concepts to historical Shanghan theories from Zhongjing to Ming-Qing dynasty and comparisons of synchronie about their era. Essential qualities of Shanghan diseases are pathologic phenomena under the order of unification of nature and man formed through concrescence between individual human body and geo-climatico-socio-cultural environmental conditions, neither injuries by cold pathogen nor five types of exopathogenic febrile diseases. The former environmental elements can be inferred from general traits of desires and public pathological aspects of social members, and the latter personal factors from corresponding features to those pathogenic variables. In addition, the concepts of Shanghan disease are added successively up to now via Jin-Yuan's four great masters and Wenbing masters, and thus the new concepts of denotation became another connotation obtaining new signifiant. In this way, for the treatment of Shanghan diseases, new theories should be made for ranging prescription over the wenbing field; reflecting not only climatical variables but also each patient's physio-pathological features and sociocultural variables. Thereby an appropriate and reasonable therapeutical systems can be designed and can guide research direction hereafter.

Developmental dental morphological anomalies are fusion, gemination, twinning, concrescence and etc. They may cause many problems in conservative, periodontal and esthetic aspects. Fusion is a condition where two separate tooth buds unite at some stage in their development to form a bifid crown. If tooth contact occurs early, at least before the start of calcification, the two teeth may be completely unites to form a single large tooth. If tooth contact occurs after the time when a portion of the tooth crown has completed its formation, there may be union of the roots only. In fusion the dentin is always confluent. Fusion teeth is more common in the deciduous than in the permanent dentition. Fused teeth are relatively rare, and are mostly mandibular anterior teeth. Fusion of normal and supernumerary teeth or between normal teeth may occurs. The exact etiology factor of fusion is unknown, but genetic and environmental factors seems to be related. A variety of complications and subsequent treatments have been suggested on this teeth. Periodontal conditions may arise due to a groove formed at the line of fusion of the two teeth. Crowding or Protrusion with potential for malocclusion or delayed eruption of adjacent teeth. Fusion teeth appear in the anterior region, they usually cause esthetic problems. Treatments vary depending on the problem, the location, and the extent of fusion. Treatment of fused teeth has been reported from endodontic, orthodontic, periodontic, surgical and multidisciplinary. This report presents the esthetic improvements by separation of two clinical crowns. Bone reduction or endodontic treatments are not required.
