The Impact of Passive Smoking on Salivary Glutathione Peroxidase and Selenium in Relation to Dental Caries Severity among Five Years Old Children.

Background: It had been found that passive smoking may have the same harmful effect as tobacco cigarettes smoking. Aims: This study was conducted to determine the effect of passive smoking on salivary glutathione peroxidase and selenium in relation to dental caries severity.

Settings And Design: The sample consisted of 120 children aged 5 years old, classified into four groups according to the number of cigarettes smoked by their fathers daily: Passive smoking children of 5-10 cigarettes, those of 10-15 cigarettes daily, those of 15-20 cigarettes daily and non-passive smoking children of no smokers indoor (the control group).

Introduction: Early childhood caries is a multifactorial disease. Saliva plays an important role in initiation and protection against caries, and its composition is greatly affected by nutritional status. This study was conducted to determine the impact of salivary lactoperoxidase and histatin-5 on the severity of ECC in relation to nutritional status.

The effects of cigarette smoking and exercise on total salivary antioxidant activity.

Objectives: This study was conducted to determine the effects of both cigarette smoking and exercise on total salivary antioxidants and their impact on periodontal health status.
