Effect of removing impacted third molars on plaque and gingival indices.

This study investigated the effect of removal of partially erupted mandibular third molars on the plaque and gingival indices. Sixty patients were studied and assigned to one of three groups: control, asymptomatic partially erupted third molars, and symptomatic partially erupted third molars. Plaque and gingival indices were scored for the second molar to the canine in all four quadrants preoperatively and again at 6 weeks after surgery. Results show that removing impacted teeth may provide some benefit in terms of improved gingival health.
