By the late 1990s, when I was conducting ethnographic fieldwork research in Lisbon, the ‘dentists’ case’ had become a familiar trope for the presence of Brazilian immigrants in Portugal. Although it involved a small group of Brazilian and Portuguese professionals, it gained visibility in the media of both countries, escalating into a political and diplomatic quarrel, and culminating in the amendment of the 1966 Cultural Accord. I use Victor Turner’s concept of social drama to address the case as a chapter in the cyclical pattern of connection and disconnection of postcolonial Luso-Brazilian relationships. Drawing from a recent discussion on the concept of cosmopolitanism in migration studies, I employ the idea of postcolonial sociabilities to help explore the seemingly inherent ambiguities in the relationship between Brazilians and Portuguese.

到1990年代后期，当我在里斯本进行人种学田野调查时，“牙医案”已经成为巴西移民在葡萄牙的存在的熟悉的说法。尽管它涉及一小部分巴西和葡萄牙专业人士，但在两国媒体中都获得了知名度，逐步升级为政治和外交争端，并最终修订了1966年《文化协议》。我用维克托·特纳（Victor Turner）的社会戏剧概念来解决此案，将其作为后殖民巴西-巴西关系的连接和断开的周期性模式中的一章。从最近关于移民研究中的世界主义概念的讨论中，我采用了后殖民社会的思想来帮助探索巴西人和葡萄牙人之间关系中看似固有的歧义。
