This randomized controlled clinical trial aims to compare the effectiveness of Erbium laser (2940 nm), Diode laser (650 nm), combination Diode laser with fluoride varnish, and fluoride varnish alone in treating dentinal hypersensitivity. The study will recruit 96 adults aged 18-45 years with tooth sensitivity scores ≥4 on a 0-10 Visual Analogue Scale, randomly allocating 24 participants to each of four treatment groups. The primary outcome is reduction in tooth sensitivity measured at baseline, 1 week, 4 weeks, and 6 months post-treatment, with patient satisfaction as a secondary outcome. Conducted at Cairo University's Faculty of Dentistry, this 6-month follow-up study addresses the limitation of current treatments that provide only temporary relief, seeking to establish evidence-based protocols for optimal long-term management of dentinal hypersensitivity by evaluating whether laser therapies alone or in combination with fluoride offer superior and more durable pain relief compared to standard fluoride treatment alone.
