Crown Lengthening Needs and Outcomes in Adults Attending a Predoctoral Clinic.

In this retrospective study of 5,536 patients admitted over four years at a predoctoral dental clinic for comprehensive care, general dentists identified crown lengthening needs in 584 patients and 760 teeth. Only 51 patients and 68 teeth actually received crown lengthening procedures. For the other cases, patients discontinued treatment or chose extraction or restoration without crown lengthening procedures. Teeth that received crown lengthening procedures were most likely restored and functioning for at least one year.
