Unilateral Impaction of Mandibular Canine in a Down Syndrome Patient: A Case Report

Abstract

A 12-year-old female patient, with large nasal bridge, mongoloid slants, clinodactyly, saddle gap of toes, slanting palpebral fissures, and a flat facies with ocular hypertelorism was reported. The patient’s medical history showed intellectual impairment, hypothyroidism, and allergy to penicillin and cow milk. Intraoral examination revealed that there was severe crowding, with Angles class I Dewey’s modification type I. A radiographic examination showed that the root of tooth 44 has sharp dilaceration toward the mesial in the apical third. Impacted canines were measured approximately 17.5 mm from the cusp till root apex. Treatment plan included prescription for pain relief. Oral prophylaxis was followed by root canal treatment and full coverage restoration. Induced eruption was planned. This case report provides insight into various oral conditions associated with Down syndrome (DS). The treatment was challenging and it needed a comprehensive approach with a preventive dentistry practice and regular screening. Dental practitioners should be aware of DS and its effect on oral health with the main focus on an effective treatment plan.
