title: Spontaneous resolution of a periapical lesion during orthodontic treatment: a case report.
abstract: Teeth with periapical lesions can undergo successful orthodontic treatment, but conventional protocols indicate that such teeth should be endodontically stabilized prior to such treatment. A case report is presented where such endodontic stabilization was not possible, yet a chronic periapical lesion resolved as orthodontic treatment progressed. This paper will discuss the possible causes of the initial lesion, and reasons why it resolved without endodontic treatment.
  
  
  CONCLUSIONS
  This report illustrates the possible combined roles of trauma, occlusion and periodontal disease in the development of a perio-endo lesion, and how orthodontic treatment potentially relieved some of the exacerbating factors, thus enabling resolution of the infection without endodontic treatment.
