Objective: The aim: To characterize the variations in the anatomical structure of the second lower molar.
Patients And Methods: Materials and methods: In order to determine the topography of the roots and root canals of the mandibular second molar, modern imaging methods were used: orthopan¬tomography and cone-beam computed tomography.
Results: Case report: During the analysis of the orthopantomogram of the patient, the three-root morphology of the root system of 37 teeth was revealed.
Objective: The aim: Is to study the ecological and hygienic situation in the living area of 6-year-old children in terms of drinking water (micro- and macroelements), to identify its relationship with the state of mineral metabolism in children's mouths, prevalence and intensity of temporary and permanent caries.
Patients And Methods: Materials and methods:Clinical and laboratory studies were to study the objective condition of the teeth -intensity of dental caries according to the recommendations of the WHO and the method of T.F.
