Kernrechtsfrage
Whether the insurer had to cover dental treatment costs from 2010-2016 under Art. 31 KVG / Art. 18 KLV due to a speicheldrüsenerkrankung (Sjögren syndrome).
Extrahierter Entscheid
A Sjögren syndrome falls within Art. 18 Abs. 1 lit. d KLV, but coverage still depends on whether the dental damage was objectively unavoidable despite reasonable oral hygiene.
Extrahierte Begründung
The court held that the mere existence of Sjögren syndrome and mouth dryness does not automatically establish coverage for all dental damage. The decisive question is whether the specific caries and consequential damage could have been avoided by sufficient and reasonable oral hygiene; the insurer had not adequately clarified this.
