Clinical dentists perform abutment teeth preparation of vital teeth in daily practice. For convenience, some dentists always perform this procedure under local anesthesia. Pain sensitivity of the dental pulp to stimulation differs among individuals and according to sex, the site of tooth, age, preparation form, and the skill of the operator.
There have been studies on the relationship between age and pain sensitivity but not those on the relationship between age and the necessity for anesthesia (2% Xylocaine with epinephrine) . We found a correlation between age and the frequency of anesthesia.
