Filter by:The purpose of the present study was to determine the effect of passive smoking on oxidative stress and dental caries in children.A total of 180 children were included to the study as follows; 90 children exposed to passive smoking, and 90 children in the control group (unexposed controls). Also demographic data were recorded (age, gender, parental education levels, child's tooth-brushing habit and child's daily dietary sugar exposure, family income). Dental examination of children were performed and caries prevalence of the patients were recorded. Unstimulated saliva samples were collected from children. Saliva 'cotinine levels' and oxidative stress markers 'total antioxidant status' (TAS), and' total oxidant status' (TOS) were evaluated by using Enzyme-linked immunosorbent assay (ELISA). The obtained data parameters of the two groups were evaluated and comparison was performed.
The aim of the present study was to determine the effect of passive smoking on the levels of salivary TAS, TOS, LL-37 and dental status in children.In the study the parents of children were asked to fill out a complete survey about smoking habits. After filling out the questionnaire, according to the survey results, a total of 180 children were included to the study as follows; 90 children exposed to passive smoking, and 90 children in the control group (unexposed controls). Also demographic data were recorded (age, gender, parental education levels, child's tooth-brushing habit and child's daily dietary sugar exposure, family income). Dental examination of children were performed and caries prevalance of the patients were recorded. Unstimulated saliva samples were collected from children. Saliva 'cotinine levels' which are expected to increase in passive smoking group; 'antimicrobial peptide LL-37' and oxidative stress markers 'total antioxidant status' (TAS), and' total oxidant status' (TOS) were evaluated by using Enzyme-linked immunosorbent assay (ELISA). The obtained data parameters of the two groups were evaluated and comparison was performed.
The study will examine changes in the respiratory system mechanics and in respiratory physiology after exposure of subjects to passive smoking. It is about healthy non-smoking volunteers and it will be carried out through the techniques of forced oscillation with Impulse Oscillometry (IOS) technique methodology and nitrogen washout. The present study will contribute to the understanding of passive smoking consequences on the respiratory system of healthy non-smokers. Thanks to the nitrogen washout technique, changes to closing volume and closing capacity will be examined during measurement in different positions (sitting, decubitus) together with exposure to passive smoking. With IOS methodology, changes in respiratory system resistance in four positions (standing, sitting, right and left lateral decubitus) will be evaluated before and after exposure to a passive smoking environment. Results of the present study are expected to provide interesting information on the changes in measured parameters not only in different positions but also after exposure to smoking.
