To differentiate upper and lower x-ray u should know or follow the anatomical landmarks of maxilla and mandible. And for right and left, follow the dot or bump present on the x-ray film and it should always towards the occulsal surface which is facing the direction of exposure. Or simply hold the film in front of u and just see how teeth are present like it always present anteriorly towards posteriorly. According u will get to know the side.
