Question 3

What percentage of cases Tx endodonticaly had total pulp necrosis versus partial pulp necrosis or calcified canals?

Answer 3

Total pulp necrosis was diagnosed in 39 of 49 (79.6%) of teeth receiving endodontic therapy

Partial pulp necrosis was diagnosed in 5 teeth (10.2%) and 1 tooth ( 2 . 0 % ) appeared to have complete calcification of the pulp chamber

What percentage of teeth with partial or complete pulp necrosis had radiographic evidence of endodontic disease?

Answer 4

34 teeth or 57.6 % of discoloured teeth which required endodontic therapy showed radiogrpahic signs of endodontic disease

25 (42.4%) did not show any radipgraphic signs

Question 5

What percentage of discoloured teeth had partial or complete pulp necrosis?

Answer 5
