Hair Evaluation in Orthodontic Patients with Oligodontia

The study "Hair Evaluation in Orthodontic Patients with Oligodontia" examined hair in 25 orthodontic patients, 18 males and 7 females aged 6 to 24, diagnosed with oligodontia, a condition characterized by the absence of six or more teeth. The study aimed to differentiate between isolated and syndromic oligodontia in patients with low clinical expression of ectodermal symptoms. Hair disorders were found in 68% of the subjects, including hypotrichosis, loss of pigment, androgenetic alopecia, telogen effluvium, and others. The study concluded that trichoscopy and trichogram are valid non-invasive diagnostic tests for this purpose.
