Experiments have been performed in beagle dogs in attempts to evaluate the effect of orthodontic‐ and jiggling‐type trauma on the supporting structures of premolars. The results reported have unanimously demonstrated that in situations where orthodontic or jiggling forces were inflicted on teeth with a normal periodontium, or on teeth with overt signs of gingivitis, the periodontal ligament tissue reacted by transitory signs of inflammation. These phenomena occurred without a concomitant loss of connective tissue attachment and development of pathologically deepened periodontal pockets. If the jiggling trauma was inflicted on teeth with an ongoing plaque‐associated, destructive periodontitis, the resulting inflammatory reactions caused enhanced loss of attachment and angular bony defects. Furthermore, orthodontic tilting movements of teeth (intrusion) in a plaque‐infected dentition may shift a supragingivally located plaque into a subgingival position resulting in periodontal tissue breakdown.
