Dentinal hypersensitivity has been referred to as one of the most painful and chronic dental conditions, with a reported prevalence of between 4% and 57% in the general population and a higher prevalence in periodontal patients. It may also occur as a result of, or during, dental treatment. Clinicians must screen for dentinal hypersensitivity and diagnose by exclusion, determine appropriate treatment, and provide treatment and preventive recommendations. Consideration should also be given to treating dentinal hypersensitivity associated with dental treatment. Traditional treatments have included adhesive resins, fluoride varnishes, HEMA,iontophoresis, gingival grafts and desensitizing dentifrices. Other technologies include the use of bioglass particles,ACP, as well as 8% arginine and calcium carbonate paste.
