| Resumen : | El consumo de sustancias ácidas en unión a cloruro de sodio en nuestro medio es un hecho indiscutible que día a día aumenta en proporciones descontroladas, principalmente entre la población escolar y adolescente quienes recibe el estímulo de su consumo desde los centros de expendio de alimentos de los centros de aprendizaje... |
| Descripción : | In our area, the high consumption of acidic substances combined with chloride sodium, is a fact that increases every day in uncontrollable proportions, especially among school children and adolescents who receive the stimulus of consumption from their own schools and food shops. Objectives: The study aimed to assess by chemical analysis, the loss of calcium ions on dental structure, considering the contact time with abrasive acidic substances such as sodium chloride and citric acid. Also, the study aimed to identify the changes in the mass of dental units after the exposure to the mentioned substances.Materials and methodology: This study corresponds to a clinical trial “in vitro”. For this, one n samer 60 human teeth extracted for therapeutic purposes were exposed to abrasive and acid elements, the latter during 20, 40 and 60 minutes. The statistical analysis was performed with an SPSS 11.5 and Epi-info 2000 version 3.5.4. Results: The data obtained was statistically analyzed by ANOVA, Tukey and t’student tests; which allowed to determine that there is a clear loss of dental calcium (Ca) after contact with sodium chloride and citric acid solution (p samer 0.0000) during the established periods with the control group; however, this loss was not proportional in the three different times established, since there was no difference in the loss of mg/g of Ca between time 2 and 3 (p samer 0.648). Furthermore, and with respect to the total weight of the units of analysis, this contact did not cause a significant change in the mass or weight (p samer 0.8935) of the samples of experimental and control groups. Conclusions: Complementary research, clinical and epidemiological studies are needed to corroborate the results of this study and expand the assessment of other processes that are not considered in this research. |
