PURPOSE: Passive smoke, known as second-hand smoke, contains several chemicals known to be poisonous. Considering that 70-90% of non-smokers are exposed to environmental tobacco smoke (ETS), our study proposed to assign the risk of respiratory diseases among children diagnosed with caries in the deciduous teeth, by questionnaire.
METHODS: The prevalence study included 83 children (46 girls and 37 boys) mean aged 9.7 y.o. +/- 3.326 s.d. (lim: 4-15 yrs.), having one or both parents smokers and one or more treated caries in dental department of Constanta "Ovidius" University, from 01.01.2007 to 31.12.2009.
RESULTS: The results of the study revealed a mean perriod of ETS exposure of 6.9 yrs +/- 5.137 s.d. (lim: 1-12 yrs.). The increased cumulative prevalence of pneumonia, bronchitis, colds, asthma, recurent wheazing was higher among those children having more than 3 caries associated with an ETS exposure time >= 5 years [17/35 vs 6/48; χ2=7.19; OR=3.89; RR= 2.94; p < 0.008].
CONCLUSIONS: Children who are exposed to the form of secondhand smoke are at a higher risk to health respiratory complications [OR=3.89; RR= 2.94; p < 0.008] if formation of more than 3 caries in the deciduous teeth exists.
CLINICAL IMPLICATIONS: Children who are exposed to secondhand smoke, defined as environmental tobacco smoke, are at a higher risk to health complications, including formation of caries in the deciduous teeth, sinus infections, middle ear infections, pneumonia, bronchitis, colds, asthma and other lung diseases.
