Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

open access: yesThe Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Solubility in water or DMEM of F-doped MTA cements with increasing F-content

open access: yes, 2010
Objectives: Fluoride increases the expansion and retards the setting time of F-doped calcium-silicate MTA cements. These cements may be successfully used as endodontic sealer.

Preservation therapy for vertically fractured teeth with periodontal tissue regeneration using FGF‐2

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Vertically fractured teeth often have a poor prognosis, and extraction is considered the most predictable treatment. Conventional management has consisted of preservation therapy involving extraction, bonding, root restoration, and replantation of fractured teeth.
