Anatomo-topographic relationship of the teeth roots were studied by means of computer tomography (CT) on 44 passportized skulls with mandibles of people who died in the age of 20 to 52 years. Conseguently, sections of mandibles and maxillae were made out of these preparations and peculiarities of the teeth roots locations in alveolar arches were studied by craniometric method. Comparison of CT results and measurements of sections showed that CT is an informative method of assessment of the teeth roots anatomo-topographic relationship that permits to attain general true qualititative indexes, allowing to evaluate objectively the available variants of the alveolar arch structure and the teeth roots location without disturbance of the anatomic material integrity.
