Regression of Calcium Channel Blocker--Induced Gingival Enlargement in the Absence of Periodontal Therapy.

AIM
To illustrate the negative effect of calcium channel blocker (CCB) drugs on the gingival tissues and the reversibility of these lesions.


CASE DESCRIPTION
The authors examined a forty-eight year-old male patient with drug-induced gingival enlargement associated with diltiazem, a CCB drug. Prior to initiating the proposed periodontal treatment, the patient was advised to consult his physician, for a possible switch to a different anti-hypertensive drug. The patient returned to the clinic three months later with a significant regression of the gingival overgrowth, which was induced by the patient ceasing the prescribed regimen without medical consultation or periodontal intervention.


CONCLUSION
Although CCBs are effective cardiovascular drugs, they can negatively impact the oral health by promoting gingival overgrowth in some patients. Substitution of these drugs is strongly recommended prior to any periodontal intervention in order to improve prognosis and prevent recurrence, and should be done only by the medical providers.
