Key legal question
Whether the dental treatment for periodontitis caused by alleged irreversible medication side effects had to be covered by mandatory health insurance.
Extracted holding
No. The evidence did not establish a causal link between the medication taken and the periodontitis or bone resorption, so mandatory coverage was excluded.
Extracted reasoning
The lower court relied on probative medical and pharmacological opinions showing only standard, intermittent corticosteroid use, no osseous side effects from the antiviral drug, and pre-existing periodontal lesions predating the medication.
