Introduction:

smoking is associated with a wide variety of harmful changes in the oral cavity, since it alters its microenvironment and predisposes it to the occurrence of various conditions.

Objective:

to determine the possible relationship between smoking and oral conditions in adolescents.

Method:

an observational study was carried out in adolescents from "Pepito Tey" Mixed Center, in San Diego del Valle, Cifuentes between September 2016 and October 2018. The study population, made up of 208 adolescents, was organized into two strata: study group and control ones. Two probabilistic samples were selected by simple random sampling (60 adolescents in each group).

Results:

12-year-old male light smokers, who started smoking between 14 and 15 years of age and practiced this habit for less than 6 months, predominated. Dental caries, periodontal disease, dental stains, oral mucosal lesions and halitosis were associated with smoking.

Conclusions:

12-year-old male adolescent smokers predominated. Most smokers were classified as light, started smoking between 14 and 15 years of age and practiced this habit for less than 6 months. There was a significant association between smoking and oral conditions (periodontal disease, dental caries, dental stains, halitosis and oral mucosal lesions).
