Korean pupils of the 8m2 class studied the oral cavity structure using the human jaw model.
 — In the lesson, we discussed cavities, periodontitis, pulpit, and the methods of avoiding them  — says Woo Seungwon, the student of the 8m2 class.  — For instance, if you haven't visited a dentist for a long time, the cavity starts to swell, bacteria penetrate the pulp of the tooth and destroy it.
— Cavity occurs when we eat a lot of sweets and don't take care of our teeth — says Shin Jiwoo, continuing the discussion. 
— Bacterias that live in the mouth are called streptococcus. They split the sugar and form acid. This acid proceeds to destroy the tooth enamel. But what about periodontitis and periodontosis? Because of them, the bone that supports your teeth starts to collapse. These diseases are connected with deficiency of vitamins C and D. 
During the lesson, students discussed the structure of the molars, premolars, and canines. Also, they learned how to brush their teeth correctly. 
— Human is an omnivorous creature, that's why the structure of our teeth is mixed. We have sharp, pointed teeth that are called canines just like predators. Besides, in total, human has 28 to 32 teeth  — explains Hong Gain.
 — We are trying to make interesting practical lessons for students to be fully engaged in the process of studying new material  — says Olga Shevchenko, the principal of International linguistic School.  —  For this purpose, we buy 3D models, interactive maps. This year pupils of our school have access to use VR glasses for studying. It is important to use additional materials and modern technologies in the education process.
