So basically the way I understand SLOB is that if you are trying to tell if something is buccal or lingual then you first take an xray, then take another one moving the PID either mesial or distal. If the object seems to move in the SAME direction that you moved the PID then it is likely LINGUALLY oriented. If the object appears to move in the OPPOSITE direction that you moved the PID then it is likely BUCCALLY oriented. Hope this helps!
Thank you! Makes sense now....
