Teeth: retained deciduous

Contributor(s):

Introduction

  • Temporary tooth remaining after eruption of permanent tooth, canines and incisors most commonly affected Retained temporary teeth.
  • If not removed, affect direction of eruption of permanent tooth causing malocclusions and gingivitis.
  • Mandibular canines: permanent tooth erupts medial to temporary - retention of temporary mandibular canines forces permanent tooth to be lingually displaced causing pain on closure of mouth as tooth impinges on hard palate/gingivae/other teeth.
  • Maxillary canines: permanent tooth erupts rostral to temporary, retention of temporary maxillary canines forces permanent tooth into space for mandibular canine when mouth closed. May result in:
    • Impaction of mandibular or maxillary canine.
    • Maxillary lateral incisor and/or canine pushed laterally by mandibular canine (often with impaction of mandibular canine).
    • Mandibular canine pushed medial relative to maxillary canine impinging on hard palate.
  • Incisors: permanent tooth erupts caudal to temporary - retention may affect scissor bite resulting in local soft tissue trauma.
  • Treatment: extraction under general anesthesia.

Pathogenesis

Etiology

  • Hereditary.

Predisposing factors

General
  • Hereditary predisposition to retention of temporary teeth.

Pathophysiology

  • Retention of temporary tooth alters direction of eruption of permanent tooth → malocclusion Teeth retained temporary upper canine (504) and lower canine (804).
  • Retention of food debris between permanent and temporary tooth → localized gingivitis Periodontitis.
