Abstract

Background

Polishing of dental composite restorations to achieve a highly smooth and reflective surface not only enhances esthetics but also their color stability and improves resistance to staining. The objective of this study was to evaluate the effect of beverages on the color stability of nanoceramic composites polished using different techniques.

Methods

80 samples of ceram. X SphereTEC one were prepared by condensing the material into a stainless-steel split mold and divided randomly into two groups. Group I was subjected to polishing using Sof-Lex system™ disks, and Group II was kept unpolished. Each group was subdivided into four sub-groups of 10 samples each. Each subgroup samples were immersed into designated beverages (Tropicana orange juice, Coco-cola, Nescafe coffee, and distilled water) for a duration of 15mins/day for 15 days. The color of all specimens before immersion, one day, and 15 days after immersion was measured using a Spectrophotometer.

Results

Significant staining of the material was found with cola drinks and coffee compared to orange juice and distilled water. Polished material showed better resistance to staining by various beverages compared to control group.

Conclusion

Nanoceramic composites exhibited superior color stability after polishing with Sof-Lex system™. Among the beverages, coco-cola significantly altered the color of the composite.

抛光工艺和饮料浸泡对纳米陶瓷复合材料颜色稳定性的影响

对牙科复合修复体进行抛光，以获得高度光滑和反光的表面，不仅可以提高美观性，还可以提高其颜色稳定性和抗染色性。本研究的目的是评价饮料对不同工艺抛光纳米陶瓷复合材料颜色稳定性的影响。方法80例陶瓷样品。X SphereTEC是通过将材料压缩到不锈钢分体模具中制备的，并随机分为两组。第一组使用soflex系统™光盘进行抛光，第二组不进行抛光。每组再分为4个亚组，每组10个样本。每个亚组的样本浸泡在指定的饮料中(纯果乐橙汁、可口可乐、雀巢咖啡和蒸馏水)，每天15分钟，持续15天。用分光光度计测定所有标本浸泡前、浸泡1天、浸泡15天的颜色。结果与橙汁和蒸馏水相比，可乐饮料和咖啡对该物质的染色明显。与对照组相比，抛光材料对各种饮料的染色具有更好的抵抗力。结论纳米陶瓷复合材料经sofl - lex系统抛光后具有较好的颜色稳定性。在这些饮料中，可口可乐显著改变了复合材料的颜色。

期刊介绍： Journal of Oral Biology and Craniofacial Research (JOBCR)is the official journal of the Craniofacial Research Foundation (CRF). The journal aims to provide a common platform for both clinical and translational research and to promote interdisciplinary sciences in craniofacial region. JOBCR publishes content that includes diseases, injuries and defects in the head, neck, face, jaws and the hard and soft tissues of the mouth and jaws and face region; diagnosis and medical management of diseases specific to the orofacial tissues and of oral manifestations of systemic diseases; studies on identifying populations at risk of oral disease or in need of specific care, and comparing regional, environmental, social, and access similarities and differences in dental care between populations; diseases of the mouth and related structures like salivary glands, temporomandibular joints, facial muscles and perioral skin; biomedical engineering, tissue engineering and stem cells. The journal publishes reviews, commentaries, peer-reviewed original research articles, short communication, and case reports.
