Objective: To evaluate the precision of dimensional measurements of the mandible in two different positions on orthopantomogram (OPG) (one with mandibular plane parallel to the floor and the other with Frankfort horizontal plane parallel to the floor) and determine the dimensional reliability. Materials and Methods: Anatomical landmarks were used to denote points for measurements on m... https://www.roneverhart.com/Burl-Audio-B2-Bomber-ADC-2-channel-AD-Converter-p17722/
