From: Students’ perspectives on undergraduate oral surgery education

 

Intra-class correlation coefficient

95%

Spearman correlation

B1. The teaching that I have received in oral surgery has given me sufficient knowledge to undertake independent practise.

0.962

(0.942–0.975)

0.940

B2. I feel confident that I could extract an upper single rooted tooth with an intact crown, in an otherwise intact dentition.

0.896

(0.841–0.932)

0.812

B3. I feel confident that I could remove visible retained roots of an upper left first molar with elevators or forceps.

0.952

(0.926–0.968)

0.914

B4. I feel confident to assess and perform the surgical management of a failed extraction (e.g. a lower second molar) necessitating: a) The raising of a mucoperiosteal flap
