Tooth wear in relation to physiochemical characteristics among a group of mixed dentition children

الملخص EN

Background: The individual susceptibility or resistance to attrition, damage (tooth wear) has been attributed to variation in the quality and quantity of saliva.

Aims of this study were to assess the tooth wear (dental attrition) among 7-10 years old children of primary school in relation to physiochemical characteristic.

Materials and methods: A study group consisted of 22 children aged 7-10years old, who had at least four teeth wear, was compared to a control group without any tooth wear matching with age, gender and number.

Tooth wear was examined by using sterile dental mirrors, Nilner and lasing criteria was used to determine the severity of attrition.

Stimulated salivary samples were collected under standard condition from the study and control group.

Salivary flow rate was determined in addition to the estimation of concentration of salivary zinc, cupper, calcium, iron ions and protein.

Results: The concentrations of salivary elements (zinc, calcium, iron, protein) were lower among the study group than the control, as well as the salivary flow rate.

All salivary elements correlated directly with tooth wear, except the cupper; this was in the primary teeth.

Conclusion: Tooth wear was found to be correlated with salivary compositions
