Outcome of Surgical Extraction of Linguoverted Deciduous Mandibular Canine Teeth, Performed as an Interceptive Orthodontic Procedure in Puppies, on Permanent Occlusion

Abstract

Linguoversion of deciduous mandibular canine teeth can be a painful condition, interferes with the development and growth of the jaws, and potentially leads to further malocclusions affecting permanent dentition. Extraction of linguoverted deciduous mandibular canines is considered an interceptive orthodontic procedure that would allow unimpeded development of the jaws and permanent teeth. This study assessed clinical records of 124 dogs that had linguoverted deciduous mandibular canine teeth surgically extracted between October 2010 and September 2019 in a veterinary dental referral clinic. Seventy-seven cases fulfilled the study criteria. Fifty-one percent of these patients required further orthodontic treatment of the permanent occlusion and forty-nine percent demonstrated atraumatic permanent occlusion. The study found no correlation of the outcome with age at the time of surgery. The class of malocclusion (class 1 or class 2) at the time of surgery was also not associated with the outcome.
