Full-coverage restorations are indicated for posterior primary teeth as definitive treatments for high caries-risk children and in patients whose treatment is being performed under general anesthesia. Advances in biomaterials and parental preferences have driven interest in esthetic full coverage treatment options for primary posterior teeth. The prefabricated resin crown offers a 'flex fit' adaptation over the anatomic cervical convexity of the primary clinical crown, similar in functionality to a stainless steel crown. A new commercial product, BioFlx, hopes to address the ductility, color stability and durability concerns that glass fiber-reinforced composite crowns have while maintaining the enticing clinical aspects, namely the flex fit, esthetic appearance and more conservative tooth preparation when compared to pediatric zirconia crowns. The purpose of this case report is to describe an alternative restorative material that can be employed to deliver an esthetic full coverage solution in a child with a potential nickel allergy.

Anterior pediatric restorations exhibit a unique treatment challenge. Factors to consider include the child's medical history, level of cooperation, dental age, caries risk, parental preferences and cultural norms regarding esthetics. The goal is to retain the anterior teeth with an esthetic result and allow natural exfoliation without the need to retreat. Anterior restorations are discussed. Rebonding traumatized fractured teeth, pediatric partial dentures, microabrasion, vital bleaching and enamel hypoplasia are also discussed.

Purpose: The purpose of this study was to investigate whether primary molars treated with composite resins (CRs) and stainless steel crowns (SSCs) during an oral rehabilitation under general anesthesia (GA1) required retreatment at a second oral rehabilitation under GA (GA2). Methods: Records were examined from 296 healthy patients with more than one dental rehabilitation under general anesthesia from June 2012 to January 2019. Data included treatment details and demographic information. Frequencies and means were recorded. An analysis was completed using logistic regression and chi-square for categorical variables. Results: For primary first molars, 43 percent of CRs placed at GA1 were treated with SSCs at GA2. For primary second molars, 35 percent of CRs placed at GA1 were treated with SSCs at GA2. There was no statistically significant difference in retreatment rates by molar type (P equals 0.27). Eight percent of SSCs placed on any molar at GA1 required retreatment at GA2. Conclusions: Primary molars treated with stainless steel crowns using general anesthesia had the lowest percentage of retreatment compared to those treated with composite resins. Strong consideration should be given to the placement of SSCs on primary molars in patients with early childhood caries under general anesthesia. Placement of primary molar SSCs during initial treatment under general anesthesia may reduce the need for additional treatment in the future. [ABSTRACT FROM AUTHOR]
