Objectives The author aimed to investigate and understand the limitations of the biopsychosocial model for irritable bowel syndrome by reviewing the priorly reported etiologies in patients with irritable bowel syndrome(IBS). Methods The author reviewed all possible previous studies related to the investigation regarding IBS in the Pub-med & Kisep database from 1977 to 2003. Results : It was impossible that patients with IBS were diagnosed and traced to a single etiology. So, the biopsychosocial model was suggested to be a new paradigm for IBS. Biological, psychological and social factors are interplaying and contributing to the biopsychosocial model affecting each other, thus affecting the biopsychosocial model. Three factors were necessary for understanding the etiology, process of symptoms and clinical outcome of IBS by virtue of their key roles in the developing, precipitating and perpetuating of the illness. However, any treatment application for those three factors faces many obstacles to be overcome. Conclusion : The biopsychosocial model contributed relatively much to the explanation but little to the treatment application of patients with IBS. Therefore, because there seems to be little practical use at present, the author believes biopsychosocial aspects should be researched further.

Although the first case of supernumerary teeth had been documented almost 20 centuries ago, the etiology of supernumerary teeth still remains unclear. The prevalence of supernumerary teeth in the general Asian population is between 2.7% and 3.4%. The pathogenesis of supernumerary teeth has been attributed to phylogenetic reversion(atavism), splitting of the tooth bud(dichotomy theory), locally induced hyperactivity of the dental lamina and a combination of genetic and environmental factors(unified etiologic explanation). This report describes 3 cases of monozygotic twins with mesiodens who visited the pediatric dental clinic of Kyungpook national university hospital, and this is significant to support genetic factors involoved in the development of supernumerary teeth.
