Analysis of mineral content of the teeth extracted for endodontic reasons using with SEM-EDX method
Abstract
Background: The purpose of this study is to investigate the changes in the mineral contents of dental tissues in various areas of the tooth using Scanning Electron Microscopy/Energy Dispersive X-Ray Analysis (SEM-EDX) method after endodontic therapy.
Methods: In this study totally 40 teeth; as twenty single-rooted human permanent teeth which were decided to be extract due to failed endodontically treated teeth and twenty single-rooted extracted human intact teeth which had no root canal therapy, no caries or restoration, extracted for periodontal or orthodontic reasons were used. The teeth were kept in 10% formalin solution until send for SEM-EDX analysis to investigate the probable relationship between mineral content of the teeth after root canal therapy and failure in endodontic therapy. While SEM-EDX analysis, half of every tooth was analyzed based on elemental content and elemental distribution from standardized three different points as apical, middle and coronal, under 300X magnification. For the purpose of measurement, the other half of the tooth was not used. During this analysis, the data related oxygen, carbon, calcium, phosphorus, magnesium, sodium, sulphur, zinc, aluminum, chlorine and Ca/P were evaluated. Statistical analysis of the data obtained from SEM-EDX was done by using One Way Anova test.
Results: According to the SEM-EDX analysis there was a significant difference regarding carbon, calcium, phosphorus, aluminum and chlorine between the root canal therapy group and the control group (p<0.01). A significant difference was not found regarding the quantity of oxygen, magnesium sodium, sulphur, zinc and Ca/P between two groups (p>0,05). There is no significant difference about apical, middle and coronal areas in any group (p>0,05).
Conclusion: In this study it is concluded that, even though there were no changes observed at various areas of the tooth after root canal therapy, there are significant differences regarding carbon, calcium, phosphorus, aluminum and chlorine minerals in dental tissue.
