Edmund (1960) has shown that in the dentitions of almost all non-mammalian vertebrates, teeth are replaced in waves which regularly sweep through alternate tooth positions. He explained the ontogeny of these patterns of tooth replacement in terms of biological units called Zahnreihen whose existence has been accepted by nearly all workers studying tooth replacement. In the present paper it is argued that there is no unequivocal evidence, either during development or in adult animals, that… 
ON TOOTH SUCCESSION IN DIADEMODON
  • J. W. Osborn
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1974
TLDR
The purpose of the present paper is to plot the sequence in which postcanine teeth were replaced in Diademodon and to compare this with tooth replacement in a polyphyodont reptilian dentition, and to conclude that the rate of tooth replacement is partly controlled at each tooth position.
The development and replacement of teeth in viviparous caecilians
  • M. Wake
  • Biology, Medicine
    Journal of morphology
  • 1976
TLDR
The general pattern of tooth replacement in fetuses and adults can be explained by either Edmund's Zahnreihen theory or by Osborn's Tooth Family theory, but replacement in fetal tooth patches and the fetal‐adult dentitional transition are explained by neither.
Tooth Replacement and Ontogeny of the Dentition
TLDR
Research on reptiles and amphibians indicate that WNT is important in regulating the activities of stem cells in the dental lamina, and hence the rate of replacement, and indeed the number and pattern of functional teeth depends on the rapidity with which the waves propagate along the dentition.
Morphological variations in a tooth family through ontogeny in Pleurodeles waltl (Lissamphibia, Caudata)
TLDR
P. waltl, a salamander easy to rear in the laboratory, is chosen as a model species to establish the morphological foundations necessary for future molecular approaches aiming to understand not only molecular processes involved in tooth development and replacement, but also their changes, notably during metamorphosis.
ON THE BIOLOGICAL IMPROBABILITY OF ZAHNREIHEN AS EMBRYOLOGICAL UNITS
  • J. W. Osborn
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1972
TLDR
Edmund (1960) introduced the Zahnreihe theory, which linked together several types of tooth replacement phenomena and he extended it to include the evolution of mammalian dentitions.
Tooth development in a scincid lizard, Chalcides viridanus (Squamata), with particular attention to enamel formation
TLDR
The results lead to conclude that tooth morphogenesis and differentiation in this lizard are similar to those described for mammalian teeth, however, Tomes’ processes and enamel prisms are absent.
A comparison of the larval and juvenile dentition in Polypterus senegalus
TLDR
The tooth pattern of a larval P. senegalus is investigated based on serial sections and 3D reconstructions, and considerable symmetry exists between apparently random patterns on both dentaries, eliciting intriguing questions on left-right control to be addressed in future studies.
EVOLUTIONARY IMPLICATIONS OF ZAHNREIHEN
  • R. Demar
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1972
TLDR
It can be concluded that the organization of adult dentitions would be identical regardless of whether Osborn or Edmund is correct on the causes of dentitions.
Preliminary investigation of variations in tooth replacement in adult Necturus maculosus
TLDR
The replacement patterns found in living and specifically killed Necturus maculosus (Amphibia: Proteidae) are surveyed to determine the nature of their variation throughout the year prior to investigating possible controlling mechanisms of the formation and eruption of amphibian teeth.
Relationship between Growth and the Pattern of Tooth Initiation in Alligator Embryos
  • J. W. Osborn
  • Biology, Medicine
    Journal of dental research
  • 1998
TLDR
Measurements made from the raw data published by Westergaard and Ferguson reveal that new teeth are added at a constant rate at the back of the jaw, and suggest that the posterior progress zone in alligator embryos grows about 125 μm a day.

On the Tooth-Replacement in Theriodont Reptiles
TLDR
In describing the very mammal-like dentitions of some of the advanced Theriodont reptiles various authors have identified premolars and molars, but there is no satisfactory evidence that only two dentitions were present or that the replacement was of a mammalian type.
Tooth replacement in mammal-like reptiles of the suborders gorgonopsia and therocephalia

  • 1956
TLDR
An investigation of two groups of the more primitive therapsids, the Gorgonopsia and the Therocephalia, which lie close to the main line of synapsid evolution, finds that after a certain time in the animal’s life tooth replacement ceased, the permanent upper canines being always borne by the anterior alveoli.

TLDR
The establishment of a series of stages which show intermediates between typical fish structures and those of the homologous organs in Amphibia may be regarded as a solution to the problem of the origin of the Amphibia.
