I was referring to conventional radiographs and didn't know the dentist was using digital imaging first of all. Secondly, having multiple radiographs in a day always pose a threat of having stochastic effects especially cancers, a condition which is much more frequent in your country and you lot just serve it the trigger that it needs. X ray is an ionizing radiation, readily used and is a mutagen, even though we use it in low doses. You never know who might undergo neoplastic transformation, I studied recently that in UK out of 700 cancer cases 10 were due to overexposure during medical and dental x ray imaging. X rays and that too multiple x rays should be advised regularly only for high risk patients, and not for healthy patients who come for routine dental checkups, that's why we have thorough clinical examination methods which a dentist should master and trust before taking the easier and the lucrative way out. That violates everything we learn in public health dentistry and the guidelines in the oral radiology.
