In the analysis of radiographs in practice, to quantify bone mineral density is rather problematic. X­ray evaluation of the minimum change in tissue density, which can be investigated visually to be significant and consti­ tute more than 40 %. The material for the study presented in the paper can be considered as monitoring of the maxillofacial area with evidential aspects based on imaging in combination with a set of different control methods. Accurate quantification of bone mineral density, according to conventional radiography, became possible only when the relative performance evaluation of bone density and benchmark studied (aluminum wedge test) with known parameters density. The basis of most modern techniques of quantification of bone mineral density, based on the principle of X­ray . Densitometry – a diagnostic study that combines different methods of obtaining images, the quantitative analy­ sis, whose main task is to determine the bone mineral density of the object. Radiographic absorptiometry is an advanced study using the principle of radiographic deficiencies related to the thickness of soft tissue. These high quality radiographs analyzed electronically. Evaluation of bone density is used to accurately determine bone density of different parts of the skeleton, including a large covered with soft tissue thickness. Single photon absorptiometry method is based on the amount of bone mineral, while easing the flow of photon energy when passing through bone and soft tissue. Well, the same principle and method based on 2­foton absorp­ tiometry. However this system uses isotope emitting a maximum photon energy in two different photovoltaic ranges. The next generation of scanners has become fan flow. Scanners with flow converge, parallel flow using X­rays, moving in straight lines with a single detector. Image resolution thus greatly increased, and the image quality is comparable to conventional radiographs. Therefore, highly informative condition monitoring bones maxillofacial dental patients, it is recommended to combine the above mentioned methods of monitoring the state of bone tissue, depending on the location and na­ ture of the useage of diagnostic and therapeutic measures.
