[Dental pulp and dentin reaction to oxyphosphate cement]

Tetracycline labelling was employed to assess pulp and dentin reactivity to the use of oxyphosphate cement in the dog. A comparison was made of dentine conditions below control cavities and those containing the cement. In the former, the pulp and dentin response consisted of enhanced dentinogenesis, whereas in the latter this parameter showed no particular changes throughout the experimental period.
