Abstract
Objective: to report a clinical case of dental pigmentation by ferrous sulfate. Case Detail: Patient, 8 years old, came with his parents to the CESUPA Children's Dentistry Unit complaining about dental black stains. In the anamnesis, those in charge reported that the patient underwent treatment with ferrous sulfate for iron deficiency anemia. In the clinical examination, the presence of mixed dentition and good oral hygiene was verified; however, blackened pigmentations at the level of tooth enamel were observed. Therefore, dental treatment was divided into two sessions; being the first session performed with prophylaxis through Prophylactic Pastes, Pumice Stone and Robson brush; and the second session, performed with bicarbonate jet and Gracey's curettes. The patient was undergoing a period of 4 months, and when he returned, the recurrence of pigmentation was noted; due to resumption of treatment; making oral intervention impossible. After 1 month, having finished his medical intervention, the patient returned to the dental treatment for the removal of the pigmentations, using the same previous method, requiring only one session; seen the reduction of pigment intensity. Conclusion: It is essential to remove the stains both for non-impairment of the marginal periodontium and for non-involvement in the aesthetics.
