Carestream Health’s Shipments of Innovative Wireless DRX Detector Reach New High

Affordable Digital X-ray Systems Provide Immediate Images in Diverse Patient Care Settings

ROCHESTER, N.Y., Jan. 24 — High-quality, affordable digital X-ray images in about four seconds— with wireless communication that allows clinicians to immediately view images from any location. This compelling workflow is the driving force behind the rapid adoption of Carestream Health’s flexible, wireless DRX detectors.

The company has shipped more than 3,300 DRX detectors since launching the CARESTREAM DRX-1, the radiology profession’s first wireless, cassette-size X-ray detector. Carestream’s comprehensive product portfolio serves diverse applications—from surgical suites, ER/ICU and radiology departments to clinics, imaging centers, nursing homes and field military hospitals.

The company’s family of DRX-based systems help streamline workflow, improve productivity and enhance patient care in both in-room and mobile environments. For example, these lightweight, digital X-ray detectors can be used in general radiology exam rooms and mobile units during the day, and are easily moved to serve the emergency department at night.

Carestream’s DRX-based portfolio includes the CARESTREAM DRX-1 System, CARESTREAM DRX-Mobile Retrofit kit, CARESTREAM DRX-Evolution suite, CARESTREAM DRX-Transportable System and CARESTREAM DRX-Ascend System.

The DRX family also includes a second detector, the cesium iodide-based CARESTREAM DRX-1C, that offers exceptional image quality and improved DQE (detective quantum efficiency). The DRX-1C detector’s superior image quality makes it an ideal fit for orthopedic, trauma, pediatric and other specialty environments, in addition to general radiography exams.

Patient care in ED, ICU, pediatric ICU and other environments is enhanced with an innovative Tube and Line Visualization feature that uses a single exposure to display an enhanced companion image with more precise visualization of lines and tubes, which are typically difficult to view. Allowing physicians to verify correct placements in seconds helps improve patient care and comfort, while simultaneously reducing the need for multiple imaging exams.

Carestream’s DRX detectors work with existing x-ray equipment and can easily be moved to any DRX room or mobile DRX system, a feature the company refers to as the “X-Factor.” Healthcare providers can also move the detectors to new imaging systems when existing x-ray systems become outdated.

Antioxidants Counteract Nicotine and Promote Migration via RacGTP in Oral Fibroblast Cells

Background: Smoking is associated with an increased risk of oral health and dental problems. The aim of this study is to address the hypothesis that nicotine impairs wound healing by increasing reactive oxygen species and inhibiting cell migration, and antioxidants (AOs) may counteract nicotine effects.

Methods: Primary human gingival fibroblasts (HGFs) and human periodontal ligament (HPDL) fibroblasts were grown to confluence, pretreated with 6 mM nicotine for 2 hours, and treated with AOs in the presence of nicotine. The pure AO compounds ferulic acid (F), phloretin (P), tetrahydrocurcuminoid Cockroft Gault (T), and resveratrol (R) were tested in single, double, or triple combinations (10⁻⁵ M). The migratory behavior at a scratch-wound edge was recorded every 15 minutes for 10 hours by using live-cell imaging. The active form of the Rho-associated protein (Rac) and guanosine triphosphate (GTP) (RacGTP) was immunolabeled and analyzed using confocal microscopy.
Results: Combinations of double and triple AOs had a greater effect than single AOs on migration rates and Rac activation. The triple combinations PFR and RFT clearly and unambiguously counteracted the effects of nicotine and significantly increased migration rates in HGF and HPDL fibroblast.

Conclusions: Treatment with AO combinations clearly counteracted the effects of nicotine by restoring and increasing cell-migration rates. We found the combination of PFR was the most effective in HGFs, whereas, RFT was the most effective combination in HPDL fibroblast. These results clearly demonstrate that PF, RFT, and PFR counteract the negative effects of nicotine on cultured oral fibroblasts via the RacGTP signal-transduction pathway.

Resistance to compression of weakened roots subjected to different root reconstruction protocols

Journal of Applied Oral Science

Print version ISSN 1678-7757

J. Appl. Oral Sci. vol.19 no.6 Bauru Nov./Dec. 2011

ABSTRACT
OBJECTIVE: This study evaluated, in vitro, the fracture resistance of human non-vital teeth restored with different reconstruction protocols.
MATERIAL AND METHODS: Forty human anterior roots of similar shape and dimensions were assigned to four groups (n=10), according to the root reconstruction protocol: Group I (control): non-weakened roots with glass fiber post; Group II: roots with composite resin by incremental technique and glass fiber post; Group III: roots with accessory glass fiber posts and glass fiber post; and Group IV: roots with anatomic glass fiber post technique. Following post cementation and core reconstruction, the roots were embedded in chemically activated acrylic resin and submitted to fracture resistance testing, with a compressive load at an angle of 45º in relation to the long axis of the root at a speed of 0.5 mm/min until fracture. All data were statistically analyzed with bilateral Dunnett's test (α=0.05).
RESULTS: Group I presented higher mean values of fracture resistance when compared with the three experimental groups, which, in turn, presented similar resistance to fracture among each other. None of the techniques of root reconstruction with intraradicular posts improved root strength, and the incremental technique was suggested as being the most recommendable, since the type of fracture that occurred allowed the remaining dental structure to be repaired.
CONCLUSION: The results of this in vitro study suggest that the healthy remaining radicular dentin is more important to increase fracture resistance than the root reconstruction protocol.

Differences Between Reported And Actual Restored Caries Lesion Depths: Results From The Dental PBRN

Journal of Dentistry

doi:10.1016/j.jdent.2011.12.015

Abstract

Objective

The objectives of this research were to (1) quantify the discordance between the caries lesion depth at which dentists restored initial lesions during a clinical study (“actual depth”) and the lesion depth that they reported during a hypothetical clinical scenario (“reported depth”); (2) test the hypothesis that certain practitioner, practice, patient, and caries lesion characteristics are significantly associated with this discordance.

Methods

: Practitioner-investigators who perform restorative dentistry in their practices completed an enrollment questionnaire and participated in two consecutive studies on caries diagnosis and treatment. The first study was a survey asking about caries treatment. The second study collected data on restorations placed in routine clinical practice due to caries in patients over 19 years of age on occlusal surfaces only or proximal surfaces only. We report results on 2691 restorations placed by 205 dentists in 1930 patients with complete data.

Results

: Discordance between actual depth and reported depth occurred in only about 2% of the restorations done due to proximal caries, but about 49% of the restorations done due to occlusal caries. Practice type, restorative material used and the diagnostic methods used were significantly associated with discordance.

Conclusion

: Dentists frequently restored occlusal caries at a shallower depth as compared to their reported depth, but the discordance was very small for proximal lesions. Discordance for occlusal caries was more common when radiographs were not taken or if a resin restoration was placed.
