By applying the potassium iodide solution (KI) over the silver diamine fluoride (SDF), a silver iodide creamy white precipitate is formed which then turns clear. SDF treatment is quicker and easier compared to invasive treatment methods.

SDI continues to innovate SDF solutions by releasing Riva Star Aqua, a next generation water-based silver fluoride solution that is also effective as an SDF solution, with additional patient benefits. Similar to Riva Star (SDF), Riva Star Aqua (AgF) is also a non-invasive 2 step patented system used to desensitise tooth pain in a few drops.

SDF (Silver Diamine Fluoride) has a proven clinical history of arresting caries and treating dentin hypersensitivity for over 50 years. Riva Star Aqua is the latest innovation to the SDF treatment category. The patented water based silver fluoride solution is not only antimicrobial, it is also a bio film eliminator and a powerful desensitizer.

Riva Star and Riva Star Aqua are non-invasive dental treatments that are quick and easy to administer, making them perfect for children, the elderly and other challenging patients. Riva Star contains SDF. Riva Star Aqua contains AgF – the latest SDF innovation by SDI. Both have the same indications for use in respective countries.

Riva Star® Silver Diamine Fluoride conditions dentin, which may assist in tooth preservation, and increases bond strengths of glass ionomer dental cements when pretreating the tooth surface. The patented 2-step process results in an aesthetically pleasing appearance without staining the patient's teeth black.

2018年4月23日 · Riva Star’s FDA registration is as a new-generation silver diamine fluoride desensitizer that immediately relieves tooth sensitivity. SDI Limited has already been successful in registering Riva Star as an anticaries agent in several Latin American countries, including Brazil, Peru, and Colombia.

Riva Star from SDI is a Silver Diamine Fluoride (SDF) tooth desensitising agent and cavity cleaner. Drawing on 50 years of dental research experience and proudly developed in SDI’s state of the art manufacturing facility in Australia, Riva Star is a silver diamine fluoride solution system used to desensitise tooth pain immediately.

SDI continues to innovate SDF solutions by releasing Riva Star Aqua, a next generation water-based silver fluoride solution that is also as effective as an SDF solution, with additional patient benefits. Similar to Riva Star (SDF), Riva Star Aqua (AgF) is also a minimally invasive 2 step patented system used to desensitise tooth pain in a few ...

SDF (Signed Distance Field)在3d和2d中都有对应的应用。 在3d中光线追踪对于性能的消耗过大，所以sdf常常被用来作为物体的隐式表达，配合 ray marching 达到接近光线追踪的效果，也有比如 deepSDF 这种对于模型的隐式表达方面的应用。 在2d中，sdf常常被用来表示字体，原神的面部渲染中阴影部分贴图也是基于sdf生成的。 SDF的本质就是存储每个点到图形的最近距离，即将模型划出一个表面，在模型表面外侧的点数值大于0，在模型表面内侧的点数值小于0，如下所 …

SDF is a colourless alkaline (pH 9-10) solution containing silver (~25%) and fluoride (~5%) stabilised in ammonia. It has been used internationally for caries management for decades but is currently only licenced as a desensitising agent in the UK, with one CE marked product: RIVA STAR (SDI. Australia) – see Figure 1. Silver has been used as an
