Abstract
Scales for the assessment of surgical difficulty in the extraction of impacted mandibular third molars have been developed in terms of impactation depth, the position of the tooth, and the distance between the mandibular ramus and second molar. We propase and apply a novel numerical scale to assess surgical difficulty, based on 10 radiological parameters: impactation depth, third molar inclination, relation to the mandibular ascending ramus, Winter's distance, second molar inclination, pericoronal radiotransparency, the presence of a visible periodontal space, coronal area, and the length, shape and type of roots ofthe impacted molar. Each parameter is scored on a three-point scale (0-2). A global score of 0-5 is considered to imply scant surgical difficulty, while 6-10 involves moderate difficulty, and over 10 points great surgical difficulty. The most difficult cases on the presurgical scale required longer surgical times and ostectomy, and involved increased pain, trismus and inflammation postoperatively.
