| ABSTRACTBackground: Cerebral palsy is a major severe childhood disability. The nature of handicap seems to have definiteeffect upon the prevalence of oral disease in handicapped individuals. Controversy exists about the incidence ofdental caries and its associated salivary risk factors in cerebral palsied children. Therefore, the aim of this study was toassess the level of calcium, phosphorus, sodium, potassium and urea in unstimulated saliva and their relations todental caries among cerebral palsied adolescents in comparison to normal adolescents.Materials and Methods: Thirty institutionalized cerebral palsied adolescents and 30 normal adolescents aged 11-14years old were included in this study. DMFS/DMFT, dmfs/dmft was assessed according to WHO (1997) andunstimulated whole saliva samples were collected and chemically analyzed to determine the concentrations of thefollowing constituents: Ions of calcium, sodium, potassium by Flame Atomic Absorption Spectrophotometer whilesalivary phosphorus and urea by using colorimetric method. The average salivary flow rate was measured from thetotal volume, and salivary pH and buffer capacity was determined using pH meter. All data were analyzed usingSPSS version 13.Results: The results showed a highly significant difference between study and controls for caries as a higherDMFS/DMFT were recorded among cerebral palsied adolescents than the control group (P< 0.001). Significantlylower values of pH, flow rate and buffer capacity were found among study compared to the control group (P<0.001). The same results were recorded regarding salivary calcium, phosphorus, sodium, potassium and urea.Conclusion: A variation in salivary constituents of cerebral palsied adolescents was recorded in comparison tocontrol group; this may explain the high caries-experience among them.Key Words: cerebral palsy, Dental caries, pH; Flow rate; Buffer capacity; salivary calcium; sodium; urea; phosphorus.(J Bagh Coll Dentistry 2011;23(4):141-147). | ||
