[Root and canal morphology of maxillary first premolar in Georgian population]

Almost each stage of endodontic treatment is connected with structural peculiarities of teeth. One of the biggest challenges facing clinicians is profound knowledge of root canal systems which is different in various races and ethnic groups. This study is devoted to the investigation of anatomo-morphological peculiarities of maxillary first premolar in Georgian population. The purpose of our work is to study anatomo-morphological and anthropological data of permanent teeth among Georgian population, establish average statistical indices of tooth length, peculiarities of "canals system", make correlation of the obtained results with international statistical indices. The data obtained as a result of clinical and laboratory studies must be assumed as a basis for making new tables of anatomo-morphological statistical indices of teeth roots and canals for Georgian population. Statistical index by itself is not a universal criterion because anthropometric data of roots and canals according to nationality and geographical zones are subjected to variations. The investigation done by us is a visible example of this.
