[Oral jewelry: a review]

Oral jewelry is popular. One of the most widely spread types are so-called tooth diamonds made of composite materials which are applied to the teeth with an adhesive. Note that parents are required to sign a release form for under-aged patients in Switzerland. Tooth cap grills and gold teeth are considered status symbols within the Hip-Hop fashion scene. However, tooth ornaments favour the accumulation of plaque and can diminish the ability to articulate. With respect to jewelry in oral soft tissue especially tongue and lip piercings are of significance to dentists. Besides the systemic complications, which are mostly caused by a lack of hygiene or the failure of noting medical contraindications by the piercer, local complications occur frequently. After surgery, pain, swelling, infections as well as hemorrhages or hematomas can be observed. Long-term effects can be problematic: gingival recession can be discernes mainly in the case of lip piercings the loss of hard tooth substance in the case of tongue piercings. Because of that, conservation therapies can become indespensable. Patients wearing dental jewelry have to be aware of risks of tooth damage, and they regularly have to undergo dental check-ups. Information campaigns--for dentists as well as patients--are necessary.

Early versions in medieval textual traditions. Wolfram’s Parzival as a test case

Wolfram von Eschenbach’s novel Parzival is a courtly romance composed in German language shortly after 1200. In a project, based at the University of Bern, a new critical edition of the poem is prepared in electronic and printed form. It visualizes parallel textual versions, which, depending on particular circumstances of oral performance, have developed in the early stage of the poem’s transmission. Philological research as well as phylogenetic techniques common in the natural sciences, e.g. in molecular biology, have been used to demonstrate the existence of these early textual versions. The article shows how both methods work and how they are applied to the ongoing edition. Exemplary passages to be presented include the text of some rare fragments written in the first decades of the 13th century, which might even go back to the author’s lifetime and which allow to date the existence of the versions they belong to.
