Scardovia wiggsiae came into the limelight as potential caries pathogens in 2011, when isolated in microbiota of severe early childhood caries in the absence of S. mutans . Since then, they have been isolated from white spot lesions, deciduous pulps, in patients undergoing fixed orthodontic treatment as well as from cavitated and non cavitated carious lesions in adults . The properties of S. wiggsiae reflect its acidogenic nature. AIM: Find a correlation between salivary flow , pH, buffering capacity and Scardovia wiggsiae in saliva with children with S-ECC and without ECC. MATERIALS AND METHODS: Children categorized into 2 group were examined and scored as per WHO criteria (1997) . Saliva samples were collected at least 1 hour after meals . The flow rate (ml/min) was calculated. Immediately after collection, the pH measurement and buffering capacity measurement was done directly, using a digital pH meter. The salivary buffering capacity value was ranked into one of the following three categories: Low buffering capacity (pH < 4.5) , Medium buffering capacity (pH 4.5–5.5),High buffering capacity (pH > 5.5).One ml of unstimulated saliva sample was transferred into microcentrifuge tube containing 1ml of Tris EDTA (T.E) buffer and samples were transported to the Central Research Laboratory, Maratha Mandal’s Nathajirao G. Halgekar Institute of Dental Sciences and Research Centre, Belagavi for quantitative analysis of Scardovia wiggsiae using real time polymerase chain reation. RESULTS:The mean values of the un-stimulated salivary flow, pH and salivary buffering capacity in the group 2 were lower than those of the group 1 . However, the amount of Scardovia wiggsiae was higher in the caries patients (p=0.072) when compared to the caries-free population , with p = 0.072 . A statistically significant difference was recorded between the two groups regarding the salivary flow, 0.473 ml/min in group 1 and 0.309 ml/min in group 2 ; p = 0.000**. CONCLUSION:Considering the results of this microbiological study it can be assumed that there is a strong correlation of the acidogenic organism Scardovia wiggsiae and salivary pH . Also the S.wiggsiae count was higher in saliva samples of children with S-ECC when compared to children without ECC proving their association with the disease process in a significant manner.
