Abstract：
OBJECTIVE: The present research aimed to characterize and deduce the structure of a novel denture base copolymer containing antimicrobial triazine comonomer by nuclear magnetic resonance (NMR) and energy-dispersive X-ray (EDX) spectroscopies. Also, it aimed to evaluate the glass transition temperature (Tg) with the addition of TATA at different concentrations.
METHODS: The trial groups G10 and G20 were thermo-polymerized with triazine comonomer, whereas the control group G0 was polymerized without the triazine. NMR and EDX spectroscopies assessed copolymerization along with deducing elemental composition in mass %. The surface topographies were observed through field-emission scanning electron microscopy (FESEM). The Tg of the resultant copolymer was examined by differential scanning calorimetry. Pertinent statistical tests with relevant multiple comparison tests were exercised to compare the mean Tg of the groups.
RESULTS: The configuration of a new copolymer containing triazine comonomer was manifested with additional protons and carbon atoms. Nitrogen was detected in the EDX spectroscopy of the trial groups. The Tg of the new copolymer was higher than the G0. The triazine comonomer in the copolymer at 20% concentration exhibited the highest Tg.
CONCLUSIONS: The triazine comonomer substitution produced a novel denture base copolymer with enhanced Tg.
CONCLUSIONS: The novel denture base copolymer may possess enhanced biomechanical properties due to the TATA\'s cross-linking capability. Nevertheless, the antimicrobial property of the triazine comonomer incorporated in the denture base composition might be beneficial in inhibiting the microbial colonization on the denture\'s surface.

摘要：
目的：本研究旨在通过核磁共振（NMR）和能量色散X射线（EDX）光谱表征和推断一种新型含抗菌三嗪共聚单体的义齿基托共聚物的结构。此外，它旨在评估在不同浓度下添加TATA的玻璃化转变温度（Tg）。
方法：试验组G10和G20用三嗪共聚单体进行热聚合，而对照组G0在没有三嗪的情况下聚合。NMR和EDX光谱法评估了共聚作用，并推导了元素组成的质量%。通过场发射扫描电子显微镜（FESEM）观察表面形貌。通过差示扫描量热法检查所得共聚物的Tg。实施具有相关多重比较测试的相关统计测试以比较各组的平均Tg。
结果：包含三嗪共聚单体的新共聚物的构型表现为具有额外的质子和碳原子。在试验组的EDX光谱学中检测到氮。新共聚物的Tg高于G0。共聚物中的三嗪共聚单体在20%浓度下表现出最高的Tg。
结论:三嗪共聚单体替代产生了具有提高的Tg的新型义齿基托共聚物。
结论：由于TATA的交联能力，新型义齿基托共聚物可能具有增强的生物力学特性。然而，结合在义齿基托组合物中的三嗪共聚单体的抗菌性能可能有利于抑制微生物在义齿表面的定植。
