a Statistical significance level was defined at P = 0.05.
Number of teeth extracted for each categories of patient, and the mean bone loss according to the smoking habit or provisional prosthesis.
Student’s t test was performed to determine if tobacco use or the provisional removable prosthesis had any effect on bone loss.
