Psychosocial factors in inflammatory periodontal diseases. A review

Reviewing the literature concerning the possible rôle of psychosocial factors in the aetiology of inflammatory periodontal diseases, it may be concluded that there is evidence which strongly suggests that emotional stress is one of the predisposing factors to ANUG. On the other hand, it is not clear that the scientific evidence is sufficient to substantiate the hypothesis that psychosocial factors are of aetiological importance in periodontitis. The proposed mechanisms which may mediate the putative relationship between psychosocial conditions and inflammatory periodontal diseases remain to be tested. However, psychoneuroimmunologic studies make lowered host resistance especially interesting as a possible mechanism. Although available studies do not definitively support causal relationships, they suggest that psychosocial factors may be involved in the aetiology of inflammatory periodontal diseases, which, in turn, would relate to clinical management of these conditions.
