Kekerasan Gigi Diskolorasi Kopi Setelah Aplikasi Pasta Berbasis Gas Ozon yang Diozonisasi pada Minyak Biji Kakao 15%

Abstract

Coffee consumption is part of a lifestyle that contributes to increased tooth discoloration, which can reduce dental esthetics. One material used to remove stains from teeth is ozone gas, which works through an oxidation mechanism. The stability of ozone gas can be enhanced when formulated in an oil-based preparation. Cacao seed oil can be used as a carrier medium for ozone. This study aimed to analyze the hardness of teeth experiencing coffee-induced discoloration after the application of an ozone gas–based paste at different concentrations ozonized in 15% cacao seed oil. The samples consisted of 24 premolar teeth divided into four groups (n = 6): ozone gas concentrations of 15 μg/mL (Group I), 20 μg/mL (Group II), 25 μg/mL (Group III), and a group without ozone (Group IV). The premolar teeth were immersed in robusta coffee solution at 70°C for seven days, with the solution replaced daily. Cacao seed oil was extracted using the Soxhletation method and ozonized according to the concentration assigned to each group. The preparation was formulated into a paste and applied to the buccal surface of the samples, then wrapped for 7 hours per day for 14 days at 37°C. Tooth hardness after treatment was measured using a Vickers Hardness Tester. The results showed that the highest tooth hardness value was observed in Group III (236.72 ± 5.37 VHN), followed by Group II (242.61 ± 6.75 VHN), Group I (246.90 ± 8.09 VHN), and Group IV (232.04 ± 10.87 VHN). Based on the one-way ANOVA test, there were significant differences in tooth hardness among the treatment groups (p < 0.05). It can be concluded that an ozone gas–based paste with different concentrations ozonized in 15% cacao seed oil can increase the hardness of teeth experiencing coffee-induced discoloration. Higher ozone concentrations result in higher tooth hardness values.
