● Other reasons ー too wide cavity preparation, sharp ‘axiopulpal line angle’. So bevel this axiopulpal line angle
● If asked specifically about primary tooth isthmus # - shallow preparation
● If asked specifically about permanent tooth isthmus fracture – sharp axiopulpal line angle .
Q. The most common immediate ttt. Reported for fractured teeth was 25%.
3. AMALGAM BLUEING (TOOTH)
● Seepage of amalgam contents upto DEJ causing blue discolouration.
● Management ー prior application of varnish.
4. AMALGAM TATTOO (MUCOSA)
