The Use of Dentifrice-Associated Boosters in the Reduction of Dentin Hypersensitivity: Case Series

Dentin hypersensitivity (DHS) is a frequent clinical condition in dental practice, characterized by a short, sharp pain elicited by thermal, tactile, evaporative, osmotic, or chemical stimuli. Management strategies for DHS encompass both in-office procedures and at-home care. Although numerous agents primarily dentifrices are available for clinical use, no definitive gold-standard treatment has been established. This case series aimed to assess the effectiveness of dentifrices formulated with REFIX technology, used in conjunction with a booster, in reducing DHS. Patients were evaluated using the air sensitivity scale described by Schiff et al. (1994) and visual analog scales (VAS) across seven time points: baseline; after scaling and root planing; following professional prophylaxis with the agent; and after 1, 2, 4, and 8 weeks of at- home use. A significant reduction in DHS was observed in all participants, as reflected by both examiner assessments and patient-reported outcomes. Mild fluctuations in symptom severity occurred, particularly among individuals with dif ficulty modifying contributing habits. Nevertheless, all patients demonstrated a substantial decrease in DHS after eight weeks of treatment. KEY WORDS: dentin; dentin desensitizing agents; dentin hypersensitivity; dentifrices;
