Questão jurídica principal
Whether the dental injury during mastication qualified as an accident under social insurance law.
Decisão extraída
The injury was not shown with sufficient probability to have been caused by an external extraordinary factor; accident status was therefore not established.
Fundamentação extraída
The insured never identified the alleged foreign body precisely or described it in detail. The evidence allowed equally the possibility of an ordinary rice grain or other food element. Medical opinions on traumatic origin did not prove the presence of an exogenous object.
