Background. One of the morphological criteria of clinical importance is the asymmetry (symmetry). Aim. Of the research was to study the asymmetry (symmetry) of the location of the mental foramen of the lower jaw in women with various defects of the dentition by Kennedy from the point of view of the anatomy of identical objects. Material and Methods. The asymmetry (sym metry) of the mental foramens was studied on 21 computer tomograms (CT). In the research triangulometry of the mandible was used. All patients were assigned to the second period of middle age. The defect of dentition was assessed by Kennedy (E. Kennedy, 1923). Results and Discussion. On CT of women with dentition defect of class I it was revealed that the average area of the right triangle was 197.03±25.00 mm2(p≤0.05), and the average area of the left triangle was equal to 168.28±21.97 mm2 (p≤0.05). The coefficient of variation of this parameter showed more pronounced average oscillation on the right side. Complete symmetry of the location of the mental foramen on CT in women of the second period of middle age was not observed. Conclusions. Thus, for the mental foramen in women of the second period of middle age is characterized by significant variability of location. And in persons with a defect of the dentition of class I on the right side it is more pronounced, while with a defect of the dentition of class III it is more pronounced on the left side.
