Abstract

Background: Depression is a common mental disorder that presents with depressed mood;it can become chronic orrecurrent and affect dental health .Thus this research aimed to assess the prevalence and severity of dental cariesamong students with different grade of depression in relation to physicochemical characteristics of stimulated wholesaliva.Materials and methods: The total sample involved for depression status assessment is composed of 800 students forboth gender aged 15 years old that were selected randomly , This was performed using children depressioninventory (CDI) index that divided the students into four groups of depression(low or average grade, high averagegrade, elevated grade and very elevated grade). The diagnosis and recording of dental caries was by using decay,Missing, Filled surface index (DMFs); and according to the criteria ofManji et al (1989), Salivary samples was collectedfrom 30 student with very elevated grade of depression and 30 from low or average grade under standardizedconditions, then analyzed for measuring salivary flow rate and viscosity, in addition to estimation salivary elementsthat includes total protein, zinc, copper, chromium and Lithium.Results: the data of the present study showed that the percentage of Caries free students was higher among veryelevated grade (8.60%) followed by low or average grade (8.52%), the less was among elevated grade ofdepression (5.04%).Concerning caries experience, the highest result was among elevated grade of depressionfollowed by low or average grade, the lower result was among high average grade. While the sever grade of dentalcaries (D4) was found to be highly significant differ among different grade of depression, The data analysis of salivaryelements found that the protein was higher in very elevated grade than low or average grade while other elementsshow the opposite result with significant concerning copper and zinc among very elevated grade that showsignificant difference. DMFs correlated negatively with salivary flow rate among low or average grade and veryelevated grade; while concerning salivary viscosity, the correlation was direct with DMFs. With highly significant invery elevated grade, Salivary elements show positive relation with not significant except copper that show negativerelation with significant.Conclusion: The results of the current research revealed that depression status had an adverse effect on salivaryphysicochemical characteristics and dental status including caries experience
