Surveillance of salivary properties of pre-orthodontic patients in relation to age and sex

Abstract Saliva plays an important role in masticatory function and protection from dental caries. Although studies have been conducted on saliva properties, their results vary widely depending on population settings. Hence, this study was performed to evaluate the results of saliva properties in in...
