540 - Comparison of Strip Crowns and Zirconia Crowns in Primary Maxillary Incisor Teeth: A Systematic Review

Background and

Purpose: Esthetic restorations are very important in dentistry, even within pediatric dentistry. Resin strip crowns have long been used for esthetic restorations in primary maxillary anterior teeth needing full coverage. Prefabricated zirconia crowns more recently have been introduced as an alternative to resin strip crowns for primary maxillary anterior teeth. The purpose of this systematic review was to compare the clinical success of prefabricated zirconia crowns to resin strip crowns in maxillary primary incisors to help develop a protocol to recommend to clinicians.

Methods: The following databases were searched: PubMed, Web of Science, EBSCOhost, and the Journals of the American Academy of Pediatric Dentistry (AAPD). Randomized clinical trials published within the last 10 years in English evaluating the clinical success of prefabricated zirconia crowns and resin strip crowns in maxillary primary incisors were included. Data collection is still ongoing currently. Risk of bias will be performed using the Cochrane risk-of-bias tool.

Results and

Conclusions: A total of six articles from the databases searched met the inclusion criteria. From these articles, the following conclusions were made: zirconia has lower plaque retention than strip crowns, restoration of failure of strip crowns was higher than zirconia, and crown retention, durability, and wear to opposing dentition was higher for zirconia crowns.
