الملخص EN

Melanin is an endogenous pigment responsible for human tissue coloration of the skin, mucosa, hair, eyes and parts of the brain.

Melanin pigmentation in the oral mucosa occurs as a result of several reasons one of which is smoking.

Cigarette smoke induces different side effects in the people who do not smoke, but in the same environment.

to find the relation between parents who smoke and oral pigmentations in their children, for this reason , our research was done.

These samples were selected randomly for samples of children in Babylon city- Iraq, in period from April 2013 to July 2014.

Oral photographs of 155 children, aged 6- 16 years were selected randomly from the children.

All these samples were examined for the presence of macules of melanin pigmentation on the gingiva and the pigmentation pattern and localization were registered.

The Chi-square test was used for statistical analysis.

In this research, 155 children, with 6-16 years of age were examined in two groups of samples.

The age of the two groups was similar.

Ninety six children (who served as experimental group), had oral pigments with parents who smoker), another 59 children (control group) had oral pigments whom parents were non- smoker).

(61.9% of children that parents who smoke had oral pigments) and (38.0% of children that parents who non- smoking had oral pigments as normal racial pigmentation).

Passive smoking may induce gingival pigmentation in children
