Gabriel-Philippe de la Hire and the discovery of Hunter-Schreger bands

Observations of Hunter-Schreger bands.

DOURING the process of studying the physical damage and traumatic effects of various instruments on tooth structure, it became apparent that some consideration should be given to the Hunter-Schreger band formation as it exists in enamel structure. When examined by reflected light, these bands appear as alternating light and dark areas in the enamel portion of a longitudinal groundtooth section,...

cannot tell, just by looking at it, what the status of the work is. Comparison with the Latin and with earlier translations reveals that it can lay claim only to being a "version", and a very idiosyncratic one at that. Certainly it makes reasonably smooth reading, but if we are interested in what Harvey said or meant, it will still be necessary to go back to the Latin; and going back to the Lat...

Diversity and evolution of Hunter−Schreger Band configuration in tooth enamel of perissodactyl mammals

Four different Hunter−Schreger Band (HSB) configurations were observed in the teeth of fossil and extant Perissodactyla. This variability exceeds that observed in Artiodactyla or Proboscidea. The four HSB configurations represent two different evolutionary pathways. Transverse HSB found in many mammalian taxa outside the Perissodactyla represents the most primitive HSB configuration. It occurs ...
