Abstract

Background: Osteoporosis is a systemic skeletal disorder affects general health in addition to effect on salivaryphysical and chemical composition which lead to an adverse effect on oral health status. This study was conductedto evaluate the concentration of glycoprotein (osteonectin) in saliva and its effect on dental caries in relation tosalivary flow rate and viscosity among osteoporotic women and compared to control group.Materials and Methods: The total sample composed of 60 females aged 60-65 years attending Al-Yarmook TeachingHospital, 30 females diagnosed with osteoporosis by measuring bone density at the spine and femur with a dualenergyX-ray absorptiometry at T-score of >2.5, and 30 women without osteoporosis with T-score of -1 (controlgroup).The diagnosis and recording of dental caries was through the application of D1-4MFS index according tocriteria of Mühlemman (1976). Stimulated salivary samples were collected under standardized condition, accordingto Tenovuo and Lagerlöf, (1994). The flow rate and viscosity were estimated and then the saliva was analyzed forestimation of glycoprotein (osteonectin) by using Enzyme-linked immunosorbent assay (ELISA).Results: The percentage of dental caries occurrence was 100% among osteoporotic group and control group.Results revealed that DMFS value was higher but statistically not significant among osteoporotic women, ConcerningDMFS components, the data of the present study showed that the DS was lower but statistically not significantamong osteoporotic women, while MS value was significantly higher among them (t=2.044, P<0.05, df =58), on theother hand the opposite figure was found concerning filling component FS however the difference was notsignificant.Correlation coefficients of caries experience with salivary flow rate revealed a weak negative not significantcorrelation with D1-4MFS and its component.On the other hand, the data of the present study showed that salivaryviscosity correlate weakly not significant in negative direction with DS and its severity and in positive direction withMS, FS, DMFS.. The correlation coefficient between salivary osteonectin and dental caries were weak significant inpositive directions concerning Ds and its severity except D3 and FS component as the relation were in negativedirection, the positive not significant relation were also found between salivary osteonectin and MS,DMFS.Concerning the relation between salivary osteonectin and physical properties of saliva, the data of the present studyrevealed a non-significant relation in negative direction with salivary flow rate and in positive direction for salivaryviscosity.Conclusions: Dental caries revealed lower percentage of occurrence among osteoporotic group
