Dental difficulty for adult patients undergoing different dental procedures according to level of dental anxiety.

: This study aimed to determine the level of dental anxiety before different dental care procedures. A group of 116 adults presenting for the first time at a French dental hospital were included in the study. These patients completed a French-language version of Corah's Dental Anxiety Scale 1 and used a visual analogue scale to score their perception of the level of difficulty generated by 13 different dental treatments. The acts perceived as the most difficult to face were root canal and restorative treatment without local anaesthesia (LA), followed by oral surgery. There was a positive correlation between DAS score and level of difficulty experienced during dental treatment. Healthy subjects declared difficulty in coping with dental care. Dental procedures may be a factor of co morbidity in terms of the psychological status of dental patients. A classification of dental procedures is given according to the level of difficulty generated.
