Comparison of the kinetic frictional force between conventional plastic brackets with thermoplastic low-friction module ligation and self-ligating brackets.

Aim: To compare the kinetic frictional force of a conventional plastic preadjusted bracket with thermoplastic low-friction module ligation and a self-ligating bracket.

Materials And Methods: The testing model consisted of four 0.022-inch conventional plastic preadjusted brackets; four 0.

Frictional resistance in plastic preadjusted brackets ligated with low-friction and conventional elastomeric ligatures.

Objective: To compare frictional resistance of the plastic preadjusted brackets ligated with the low-friction ligatures with those of the conventional elastomeric ligatures.

Design: In vitro study.

Setting: Department of Orthodontics, Faculty of Dentistry, Kyushu University, Fukuoka, Japan.

Facial onset sensory and motor neuronopathy (FOSMN) syndrome responding to immunotherapies.

We report the first non-Caucasian case of facial onset sensory and motor neuronopathy (FOSMN) syndrome partially responding to various immunotherapies. A 55-year-old man had first felt paresthesia on his right cheek at age 45. This gradually extended to the scalp.
