Damage of the dental pulp as a result of non-function movements such as the patient's chewing habits or teeth grinding,

Pulp damage after advanced gum diseases or gingival operations,  The determination that pulp has lost its vitality.

  • In cases where it is considered that the pulp of crowded teeth will be damaged due to restorative procedures,
  • In cases where the pulp is found to be infected,
  • In cases where the severe gingival problems affect the vitality of the tooth,
