    Introduction: Malnutrition in children is epidemic in developing countries. Several health issues and consequences are believed to develop due to this phenomenon. Children’s oral health is also affected by malnutrition. The main aspects of oral health status are caries experience, the existence of cariogenic bacteria, and salivary immunoglobulin A. Materials and methods: This comparative study included 87 school children aged 12 years. Participants with systemic disease were excluded. An oral examination was conducted to record the DMFT score, then saliva samples were collected in the morning using an unstimulated method. Salivary IgA were analyzed using Sandwich ELISA technology. Malnutrition was based on body mass index (BMI) which was computed as weight/height2 (kg/m2). Ethical approval was granted by the ethical committee at the Faculty of Dentistry. Informed consents from children’s parents were gained prior to the start of the study. Results: Compared to the normal weight group, the results of this study showed that overweight and obesity are inversely correlated with the mean DMFT and the number of S. mutans and S. sobrinus. Salivary IgA was negatively correlated with overweight and obesity, compared to normal weight group. Conclusions: Children suffering from malnutrition are at risk of developing oral health diseases. Treating malnutrition will therefore improve children’s overall oral health.

    Background: Waterpipe and cigarette are two types of tobacco consumption, their smoking is associated with many adverse effects it has a detrimental effect on saliva and causes a reduction in salivary pH and flow rate in addition to their controversial effect on salivary IgA and lactoferrin. Materials and Methods: unstimulated saliva was collected from 84 subjects in the early morning between 8-10 am. Subjects were divided equally into three group’swaterpipe smokers, cigarette smokers, and non-smokers all of the participants are adult male aged between 25-60 years, Sandwich ELISA technique was used for detection and estimation the level of salivary IgA and lactoferrin. Result: IgA and Lactoferrin results showed significantly(p≤0.01), higher concentration in cigarette and waterpipe smokers group than nonsmokers Results also showed that Salivary flow rate(SFR) and pH was higher in the non-smoker’s group followed by waterpipe and cigarette smokers groups with a highly significant difference (p≤0.01), The correlation between Lactoferrin and salivary IgA also showed a significant (p≤0.01),moderate positive correlation in the cigarette group only. Conclusions:Smokingincrease Salivary IgA and lactoferrin concentrations while it reduces SFR and pH of saliva, a significant positive correlation was founded between lactoferrin and salivary IgA only in cigarette smokers

    Background: Waterpipe and cigarette are two products of tobacco consumption, tobacco use has detrimental effects on the oral cavity, numerous studies around the world have reported a significant relationship between smoking and increase dental caries and viable count of cariogenic bacteria, Materials and Methods: unstimulated saliva was collected from 84 subjects and divided equally into three groups waterpipe smokers, cigarette smokers, and non-smokers all of the participants are adult male aged between 25-60 years, dental caries was measured by use DMFT index, while S.mutans and S.sobrinus were isolated by using a selective medium SB 20M (Sugar bacitracin-20 modified) agar Results: this present study showed a significant (p≤0.01). higher DMFT, DT, MT, and FT among cigarette smokers group than both waterpipe smokers and non-smokers groups. The viable count of S mutans was significantly (p≤0.01).higher in the cigarette smokers group followed by the waterpipe smokers group and then the non-smoker's group, while the viable count of S sobrinus showed no statistical differences (P>0.05) between groups. The correlation of DMFT with S.mutans, and S sobrinus count, were significantly positive (p ≤0.05), in the cigarette smokers group only Conclusion: Dental caries increase in cigarette smokers, where the DMFT and S mutans viable count are less affected by waterpipe than cigarette smoking, a positive correlation is found between DMFT and .mutans streptococcus count only in cigarette smokers
