Influence of Different Protocols on In‐Office Bleaching: Whiteness Difference and Hydrogen Peroxide Penetration

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate whiteness difference (WID) and hydrogen peroxide (HP) penetration into the pulp chamber in extracted teeth subjected to various in‐office application protocols. Materials and Methods A total of 154 human premolars were randomly assigned to 11 groups (n = 14). The groups were divided into: Pola Office+ and Pola Rapid (SDI)

Life history data derived from the dental histological analysis of Giraffa camelopardalis: Implications for the palaeohistology of extinct giraffids

open access: yesJournal of Anatomy, EarlyView.
The study of incremental lines in the dentine (left), cementum (centre) and enamel (right) of the giraffe revealed key information about the rate and pattern of dental growth in this vertebrate. These results were also useful to obtain data on the biology and life history of the species and sets the stage for future palaeohistological analysis in ...
