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.

Purpose: To assess the diagnostic confidence of intraoral radiographic image quality while reducing the pediatric patient's radiation exposure using a longer position indicating device (PID), additional X-ray beam filtration and rectangular collimation while using modern, lower-power intraoral dental X-ray units. Methods: A randomized prospective study scored bitewing intraoral dental images based on relevant clinical features. Observer studies with pediatric dentists and dental residents were conducted to verify whether diagnostic confidence remained unchanged after dose reduction modifications. The study involved a two-phase investigation to determine: (1) the best thickness of aluminum (Al) 2024-T3 alloy filter and (2) required increased exposure time to maintain intraoral radiographic image quality. A 30 cm PID with a rectangular collimator was used to further manage patient dose. For each phase, images from 125 patients were collected from February 2017 to September 2018 and analyzed. Results: The results from the observer study using a 30 cm PID, 1.02 mm thick Al alloy filter, and a rectangular collimator resulted in a patient dose reduction between 64 percent (exposure time of 400 msec) to 77 percent (250 msec), without any statistically significant effect to the diagnostic confidence of the observers in evaluating the reduced radiation images. Conclusion: Long recognized dose reduction methods, when implemented on a modern, low-power intraoral dental X-ray unit, do not impact confidence in bitewing diagnostic images, but substantially reduce patient dose and should be adopted to increase patient safety, especially for children.

A 13-year-old female presented with traumatized maxillary central incisors that had been endodontically treated. Five years later, at a different dental office, she had the clinical crowns removed, leaving subgingival margins. From the patient's history and our initial assessment, it seemed as if the teeth had been fractured and luxated but not avulsed. Endodontic posts with spot-welded orthodontic brackets were temporarily cemented to enable orthodontic extrusion. Once access to restorable margins was obtained, the temporary posts were removed and conventional fiber posts with interim composite crowns were placed. The restorations were still satisfactory at the one-year follow-up, with a healthy periodontium, intact apical seal, and no signs of external resorption observed. Combined specialty treatment provided an esthetically acceptable outcome in a difficult restorative situation for a growing child. The purpose of this case report is to discuss an interim treatment until the child reaches dentofacial maturity, when definitive restorations can be provided. [ABSTRACT FROM AUTHOR]
