The effect of desensitizing dentifrice with or without diode laser therapy in the management of dentinal hypersensitivity of teeth with Miller’s Class I or Class II gingival recession

Introduction: Dentinal Hypersensitivity (DH) is characterized by short, sharp pain arising from exposed dentin in response to stimuli typically thermal, evaporative, tactile, osmotic or chemical. Most common modality for treatment of DH is desensitizing dentifrices through combined use of Diode laser along with desensitizing tooth paste which has shown encouraging results. The present study evaluated and compared the efficacy of toothpaste containing 10% Strontium Chloride (SrCl2) with or without Diode laser in the treatment of DH in the teeth with Miller's Class I or II gingival recession. Materials and Method: The study included patients (aged 18 to 50 years) with chief complaint of dentinal hypersensitivity having Miller's Class I or Class II gingival recession. A total of 20 sites equally and randomly divided into two groups; Test group (Diode+ Sensoform®-SrCl2 Toothpaste) and Control group (Sensoform®-SrCl2 Toothpaste). Pre and Post treatment VAS for DH was recorded at baseline, 7, 15 & 30 day using air blast test for both the groups. Result:Patients in both the groups reported reduced dentinal hypersensitivity. However, DH was significantly reduced in test group as compared to control group at all the intervals as measured using Visual analogue scale (VAS). Also, the test group showed statistically significant decrease in VAS, post treatment at baseline itself. Conclusion:Within the limitations of the present study, it can be concluded that combined use of desensitizing toothpaste (SrCl2) and diode laser therapy can be effective in providing immediate relief from DH in patients with Miller's Class I or Class II recession.
