Clinical success of preformed steel crowns in disabled pediatric population: An 11-year retrospective study Article uri icon

abstract

  • Objective This retrospective study aimed to clinically evaluate the success/failure rate of Preformed Metal Crown (PMC) placed on primary teeth in children presenting any type of physical/mental disability who attended the CRIT (Aguascalientes City, Mexico) Pediatric Dentistry Service during 2004–2014. Methods This study was performed using the electronic database of pediatric patients with different disabilities who received dental restoration with at least one PMC in our dental department between January 2004 and December 2014. Each registry included pertinent information on the patient%27s health status and all dental procedures performed and additionally, the time elapsed in days since placement of the PMC to the date when the PMC failed (e.g., perforated, fractured, or missed). For the performance of each PMC, a survival (time to event) curve estimated was obtained using the Kaplan-Meier method, considering the censored observations during the follow-up period. Results A total of 402 registers met inclusion criteria and were included in the final analysis. With 11 failure events recorded; survival rate during briefest follow-up period (288 days) was 0.996 (95%25 CI [0.989, 1.00]), and for longest observation period (2078 days), this was 0.874 (95%25 CI [0.764, 1.00]), with very low occurrence of gingival inflammation. Conclusions PMC placed on primary teeth of physically/mentally disabled pediatric patients showed a highly satisfactory longevity time and experience of success. © 2017 Japanese Society of Pediatric Dentistry
