Study name	Treatment of hypersensitivity using diode laser and desensitising agent on fluorosed and non‐fluorosed teeth
Methods	Parallel RCT
Participants	Sample size: 90 patients Age: 18 to 60 years Inclusion criteria: patients with a positive response for hypersensitivity testing (i.e. cold water testing using ice cold water, air blow test, electric tactile stimulation test); patients presenting with non‐carious cervical lesions in the enamel; fluorosed teeth wherein fluorotic enamel staining confirmed by clinical examination, healthy non‐fluorosed teeth, which was confirmed by clinical examination Exclusion criteria: patients undergoing any form of restorative endodontic, orthodontic treatment or crown restorations; local defects including caries and fractures; presence of any systemic diseases; acute pain conditions (like apical periodontitis, periapical abscess); presence of periodontal disease or a history of periodontal treatment in last 6 months; usage of desensitizing toothpaste or mouthrinse in the last 4 weeks; patients allergic to ingredients used in the study product; teeth with intrinsic stains caused by other reasons
Interventions	Group 1: desensitizing agent (potassium nitrate) Group 2: diode laser Group 3: desensitizing agent + diode laser
Outcomes	Response to air blast stimulus, ice cold water and electrical tactile sensitivity after 30 minutes
Starting date	July 2014
