ScanX Swift Digital Imaging System
Air Techniques

Radiography has expanded the dentist’s investigative capacity in many ways: it is possible to confirm health and to detect disease in areas previously invisible to intraoral examination. Since digital dental radiography was first introduced in the late 1980s, it has provided many clinical advantages: virtually immediate clinical results, diagnostic accuracy, decreased patient radiation, convenient data storage and communication, and decreased consumable costs and environmental waste. Most digital sensors can be used with existing x-ray units as long as the radiation emission can be significantly reduced. Digital sensors are generally classified as wired and wireless. Transmitting diagnostic data to the computer can be accomplished by using a scanner, a Bluetooth connection, or a USB cable. Air Techniques’ ScanX Swift digital imaging system is an advanced and compact scanner designed specifically for in-operatory chairside use. It accepts size zero, one, and 2 digital sensors. The size 2 ScanX cordless digital sensor is particularly useful for bite-wing and periapical radiographs because it provides approximately 1,080 mm² of diagnostic area (compared to 1,100 mm² for traditional analog film). The ScanX sensor captures the complete coronal to apical length of most teeth and provides more mesial-distal and interproximal diagnostic information than most other digital sensors. Also, the thickness of the ScanX is a fraction of most wired digital sensors (0.4 mm versus 5.5 mm or more), somewhat pliable, and therefore very comfortable in the patient’s mouth. The Swift scanner automatically erases the ScanX sensors during the rapid scanning process, readying them for the next use. Sensors can be reused many hundreds of times before they are inexpensively replaced. ScanX Swift is the most economical solution for digital radiography.

GlasIonomer FX-II Capsule
Shofu Dental

Glass ionomer materials are kind to tissues, self-adhesive, and capable of releasing fluoride to assist in the remineralization of adjacent dental structures. Widely used throughout the world, glass ionomers have had a slow start in North America. The early products in this category exhibited extensive wear of the restorative surface that caused pitting and staining. As their chemistry has improved and ease of use has progressed, glass ionomers are increasingly utilized by practitioners for a variety of indications. Shofu Dental’s GlasIonomer FX-II Capsule is an enhanced direct restorative material, specifically designed for minimally invasive dentistry. It is an all-purpose glass ionomer material that provides aesthetic direct restorations, and it is indicated for nonload bearing Class I and Class II restorations in the permanent dentition and Class III and Class V cavities, including abfractions. It is also excellent for core buildups and as a base/liner material. Useful for both pediatric and geriatric patients, its Giomer technology offers a very high fluoride release rate combined with a proprietary rechargeable property that makes it ideal for high-caries-risk individuals. Its rapid self-cure (1.66 minutes total working time and 2.5 minutes total setting time from start of mixing) provides an excellent solution for subgingival cavities where light curing is not possible. Its radiopacity makes recurring decay easy to spot. FX-II Capsule also has a very low solubility in intraoral fluids, significantly decreasing acid erosion and leaving the restorative surface smooth and aesthetic in the long term. The thermal expansion is similar to natural tooth structure, minimizing marginal gap formation. The application process is remarkably easy: simply mix in the triturator and insert immediately thereafter. No conditioners are required, and it handles and packs easily. The GlasIonomer FX-II Capsule is perfect for predictable direct restorations.
