Dentine hypersensitivity: is there both stimulus and placebo responses in clinical trials?
Application of the dressing to sensitive teeth, dramatically reduced the pain of dentine hypersensitivity following tooth stimulation. When assessing subjects' response to pain-evoking stimuli, perception of pain appears to be altered by sensory factors, prompting a heightened pain response.
Stable long-term aneurysm exclusion was achieved in the majority of patients with most re-interventions occurring early in the follow up period. Whilst life-long surveillance should be continued, these data raise the question of the appropriate duration of CT surveillance and suggest that EVAR should be considered for patients with longer life expectancy and favourable anatomy who traditionally would have undergone open repair.
