Architecture and structure depend on the intensity and duration of the stimulus: 01:03:34
1- rapidly, with a sparse & irregular tubular pattern and some cellular inclusions: Osteodentin 01:03:48
2- less active, it is laid down less rapidly with a more regular tubular pattern and without cellular inclusions 01:05:11
3- Transparent or Sclerotic D. 01:05:45
4- Dead tracts D. 01:08:32
Dentino-enamel junction (DEJ) 01:11:04
Clinical consideration 01:12:57
Review 01:14:59
