Objective: Both periodontal disease and peripheral neuropathy are complications associated with poorly controlled diabetes. This study aimed to determine whether periodontal disease was more prevalent and more severe among patients with severe diabetic peripheral neuropathy.
Methods: A case-control study was performed; 46 patients with and 48 without the slipping slipper sign (SSS)-a surrogate clinical marker for severe peripheral neuropathy-were recruited from a diabetic outpatient clinic.
