Nickel and Chromium Ion Levels in Hair and Gingival Crevicular Fluid with the Corrosion of Brackets in Orthodontic Patients: A Longitudinal Study

Objective: To assess the levels of nickel and chromium ions in hair and Gingival Crevicular Fluid (GCF) of orthodontic patients and to evaluate the corrosion of orthodontic bracket surfaces. Material and Methods: Nickel and chromium ion concentrations were measured in hair and GCF of 15 patients (9 females and 6 males, aged 16-28 years old) who had fixed orthodontic treatment using atomic absorption spectroscopy. The samples were taken before treatment (baseline), 4, 8, and 16 months later during treatment. Along with ionic sampling, microscopic sampling was done. One of each patient brackets was removed to get 15 brackets per group. Five brackets were taken randomly from each group to be examined under scanning electron microscope (SEM). Data obtained were analyzed using paired t-tests. Results: After 16 months, compared with the baseline, average hair nickel level changed from 0.125 µg/g to 0.956 µg/g with statistically significant difference (p=0.00); average chromium level changed from 0.090 µg/g to 0.295 µg/g but no significant difference (p>0.05); average GCF nickel level changed from 3.335 µg/g to 10.410 µg/g; average chromium level changed from 1.859 µg/g to 9.818 µg/g. Both of these increases were significant (p=0.000). SEM examinations showed that the corrosion on brackets was seen in the fourth month, and more severely visible after 8 and 16 months of uses. Conclusion: After 16 months of treatment, compared with the baseline, the hair nickel level was increased by 7.7 times; while for chromium was by 3.3 times. Gingival crevicular fluid nickel level was increased by 3.1 times and chromium level was by 5.3 times.

Characteristics Vertical Position of Mental Foramen Reviewed by Panoramic Radiography as a Guide in Predicting Individual's Age on Forensic Odontology Examination

Objective: To know the characteristics vertical position of mental foramen based on panoramic image as a guide in predicting the individual's age for the purposes of Forensic Odontology examination. Material and Methods: The method of this study was observational and descriptive by using the cross-sectional approach. The data is obtained from the secondary data, which is adopted by purposive sampling technique in RSGM FKG Hasanuddin University and RSUD Batara Guru Belopa, District Luwu, Indonesia. Data was analyzed by using descriptive analysis method. Results: Vertical position of mental foramen is mostly affected by age, but there are some cases where the Vertical position of mental foramen is not affected by the individual's age. Before the eruption processof permanent tooth finish, mental foramen is located closer with alveolar ridge. After the eruption process of permanent tooth, slowly mental foramen is moving halfway to the lower border of corpus mandible. As each individual grows older and resorption process occurs to alveolar bone, mental foramen will appear moving closer to alveolar ridge. Conclusion: The process of identifying mental foramen to predict individual's age in the relation with forensic odontology is possible to be done by using roentgen image in mandible of the dead victim. Although it still requires further identification, mental foramen position can be one of the references in predicting individual's age.
