title: Gingival overgrowth and drug association: a review.
abstract: Drugs used locally or systemically induce several alterations in micro and macroscopic tissues. However, nearly 20 drugs have been reported so far in the literature associated with gingival enlargement. Many systemic diseases have limited therapeutic options and such drugs or their metabolites have an adverse influence on different systems/organs, and one of these is that they initiate or accelerate the overgrowth of gingival tissue. The increase in size may be to the extent that teeth may be partially or completely covered, and the resultant 'gummy smile' may result in aesthetic concern for the patient.In the presence of bacterial inflammation in the gingiva, many of these drugs enhance the production of collagen by fibroblast cells, and simultaneously retard the destruction of collagen and hence increase the bulk of gingival tissue. It is apparent that there is a subpopulation of fibroblasts which is sensitive to these drugs. The exuberant growth of gingival tissue is of great aesthetic concern, which may require mechanical removal of bacterial plaque, calculus, and surgical intervention, and/or substitution of the drug with analogs. A relatively healthy oral environment provided by the dentist will reduce local microflora that will help in eliminating the major focus of infection. Physicians, general practitioners, and dentists need to make a coordinated and concise treatment plan that will be beneficial for the patients. This article will facilitate full information to physicians to involve dentists in the multidisciplinary treatment plan.
