This study was conducted to assess the physiochemical characteristic of salivaamong caries experience preschool children and compared them with caries free matching in age and gender.Then an evaluation was done about these salivary characteristics to dental caries and evaluated the relation ofbody mass index to dental caries and to salivary variables.Materials and method: After examination 360 children aged 4-5 years of both gender. Caries-experiences wasrecorded according to dmfs index by (World Health Organization criteria 1987) during pilot study children with cariesexperience was divided in to three groups according to decay fraction of decay missing filled surfaces index .Mildwith decay surfaces<6, moderate with 6≤decay surfaces≤13 and severe with decay surfaces>13 and select thirtychildren with moderate caries experience and compared with thirty caries free children decay missing filledsurfaces=0 match in age and gender. Nutritional status of each child was assessed by measuring weight and heightto calculate body mass index. Unstimulated saliva collected from sixty child under standardized condition andpotential hydrogen and flow rate were measured. Total antioxidant concentration, total protein, calcium, inorganicphosphorus, zinc and copper were measured.Results: Statistically highly significant differences were found in concentration of salivary calcium and inorganicphosphorus between caries-experience and caries free children with higher mean value among caries free group.Statistically significant differences were found in concentration of salivary zinc between groups. Statistically nonsignificantdifferences were found in concentration of salivary total antioxidant, total protein, copper and body massindex between caries experience and caries free groups.Salivary flow rate and PH showed statistical non-significantdifferences between groups. Positive non-significant correlation was found between dmfs index, (ds) fraction of dmfsindex and salivary flow rate, total antioxidant and negative correlation with salivary PH, total protein, calcium,phosphorus, zinc and copper. Positive a non-significant correlation was found between BMI, salivary flow rate, PH,total antioxidant, zinc and copper while a negative weak correlation found with dmfs, ds fraction of index andsalivary total protein, calcium and inorganic phosphorus in caries experience group. Furthermore a non-significantpositive correlation was found between BMI, salivary flow rate, PH, total antioxidant inaddition to that negativeweak correlation was found with salivary total protein, calcium inorganic phosphorus, zinc and copper among cariesfree group.Conclusion: The findings of the present study showed that inorganic components of saliva play an important role inreminerlization of incipient caries and there is an inverse association between body mass index and dental caries
