It has been claimed that the imbalances in levels of free radicals, reactive oxygen species and antioxidants in saliva play an important role in the onset and development of dental caries. Objectives: To study the correlation between children’s Total Antioxidant Capacity of saliva and caries experience. Methods: Total antioxidant capacity of saliva was investigated in 60 healthy children aged 8-10 years where dental examination was carried out in accordance with the recommendation of the World Health Organization. Food frequency questionnaire was filled and saliva samples were collected from all groups where salivary total antioxidant capacity was estimated by an adaptation of the ABTS assay. Results: There was a statistically significant positive correlation between total antioxidant capacity and deft. Conclusion: we can conclude that total antioxidant capacity play a role in the development of caries.
