- Fish (1933) showed that dyes penetrated dentine when placed under fillings in dog teeth in vivo.
- Anderson and Ronning (1966) showed that Evans’ blue diffused readily through dentine in extracted human teeth if the tubules were not occluded.
- Vongsavan and Matthews (1991) demonstrated that outward flow of dentinal fluid through exposed dentine opposed inward diffusion in vivo but not in vitro.
- Bishop (1985) and Turner et al. (1989) demonstrated that the tight junctions between odontoblasts have a low permeability but open when dentine is exposed.
- Jontell et al. (1994) showed plasma proteins in dentinal fluid under exposed dentine.
