Today smoking is a modified risk factor for the formation and progression of major dental diseases. Oral cavity (ОС) is the first barrier to tobacco smoke with toxins and carcinogens that are part of it. Thus, the question of studying the impact of bad smoking habits on the dental status of adolescents and young is relevant.

Purpose - to examine the effect of bad smoking habits on dental status in adolescents and young adults.

Materials and methods. The dental status of 114 adolescents and young people (15 to 24 years old) was studied, which were divided into groups: Group I involved 26 people who regularly smoke traditional cigarettes; to the second group - 22 people who regularly smoke electronic cigarettes (Vapi); to group III - 23 people who regularly smoke tobacco heaters (IQOS); to group IV - 43 people without a bad habit of smoking. The prevalence and intensity of dental caries, the state of hygiene of ОС were determined using the OHI-S index.

Results. It was found that the prevalence of caries averaged 89.85%. The index of the intensity of dental caries averaged 5.84±0,39 points. The structure of the OHI-S ОС hygiene index revealed that in the subjects of the first group it was equal to 1.77±0.02 points, in the subjects of the second group – 1.53±0.01 points, in the subjects of the third group – 1.46±0.02 points. In the surveyed group IV, the index was much lower – 0.87±0.03 points. In persons of group I the value of the PMA index was 38.6±3.26%, in persons of group II – 33.7±2.52%, in persons of group III – 31.6±1.84%, in persons of group IV – 22.8±2.73%.

Conclusions. The study found a negative impact of harmful smoking habits on the dental status of adolescents and young adults.

The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local ethics committee of the participating institution. The informed consent of the patient was obtained for conducting the studies.
