 ① Review

Keypoints：

◆ Advantages for preformed metal crown：

   → Convenient; 

   → Comfortable fit; 

   → Superior longevity  and lower replacement rate.

◆ Indications of SSC:

  → An amalgam or composite resin is likely to fail in a primary  molar;

  → Extensive caries damage involving multiple  surfaces of the tooth;

  → Extensive decalcification around an already restored tooth where there is a high risk of  recurrent caries;

  → For space maintenance;

  → After pulp therapy or endodontic procedures;

  → Developmental defects;

  → Uncooperated children have their tooth repaired under genernal anesthesia.

◆ Contraindications of SSC:

  → Patient is unable to cooperate with treatment;

  → Primary tooth is approaching exfoliation.
