Practice articles (BDJ 2012; 214: 155–158, 227–231)
'An overview of electronic apex locators: part 1' and 'An overview of electronic apex locators: part 2'
In the above practice articles, the resistance given in Figure 4 (BDJ 2012; 214: 155–158) and Figure 1 (BDJ 2012; 214: 227–231) should have read 6.5 kΩ. Similarly, the following sentence (BDJ 2012; 214: 227) is incorrect:
'the electrical resistance between an endodontic instrument at the apical foramen and an electrode attached to oral mucous membrane was approximately 6.5 kW'.
This should have read 'approximately 6.5 kΩ'.
The authors apologise for any confusion caused.
