Crowns in pediatric dentistry –A Review on the failures

Abstract

Several crowns are used as full coronal restoration in primary teeth. The literature was reviewed in order to investigate the failure and the reasons for failure of pediatric crowns. Electronic databases were screened, and eligible studies were hand-searched to find clinical studies evaluating the survival of different crowns placed in primary teeth with follow-up. Among those, an elevated number of failures were reported with every other type of crown. The high variation on failure rate among the crowns can be due to several contributing factors out of which children's behaviour during the clinical procedure can be the most vital. All the factors leading to the failure of each type of crown are thoroughly reviewed and discussed.
