Cell line affects the results of toxicity studies

The choice of cell line is of no small matter when conducting in vitro studies. A recent NIOM study has shown how differently five cell lines reacted, although consistently so, when testing for their interaction with two methacrylates. The message is that the choice of cell line will largely affect the results obtained.

Stainless-steel crowns in children: Norwegian and Finnish dentists’ knowledge, practice and challenges

Stainless-steel crowns (SSCs) are recommended for restorative treatment of young teeth severely affected by caries, fractures or dental developmental disorders (DDDs). However, despite recommendations and clinical evidence, SSCs are not widely used by general dentists, who favour extraction and more conventional restorations. The present study aimed to investigate the views of and use of SSCs among Norwegian and Finnish dentists.

Allergic reaction after treatment with a mandibular advancement device

Mandibular advancement devices (MADs) are used in the treatment of obstructive sleep apnea. A patient (woman in the 60-ies) was treated with a MAD (SomnoDent Fusion Flex; SomnoMed AG). She experienced reactions in form a burning sensation in the mouth, ulcers on the tongue and gingiva, and swelling of the tongue. Allergy test (patch test) with Dental Screening Series showed a strong positive reaction to methyl methacrylate, and clear reactions to ethylene glycol dimethacrylate (EGDMA) and 2-hydroxyethyl methacrylate (HEMA).

The dream of new teeth

The dental community has for a long time been fascinated by the thought of growing a third set of teeth. This has increased research interest in the processes of embryonal development of teeth for experimental copying. However, research of this kind cannot be performed on humans for medical and ethical reasons.
