Effects of different ceramic primers and surface treatments on the shear bond strength of restorative composite resin to zirconium.

Effects of different ceramic primers and surface treatments on the shear bond strength of restorative composite resin to zirconium. Laser Ther. 2018 Jun 30;27(2):111-117 Authors: Tabatabaei MH, Chiniforush N, Namdar SF Abstract Background and aims: Data are limited about the effect of ceramic primers on the bond of zirconia to restorative resin composite. The aim of this study was to assess the effect of different surface treatments and two ceramic primers on shear bond strength (SBS) of zirconia to restorative resin composite. Materials and methods: 100 samples of zirconium ceramic blocks were randomly divided into 5 groups (n = 20) and received the following surface treatments: a)Control groupb)AL2O3 abrasionc)Nd:YAG laserd)Er:YAG lasere)Bur preparation.Next, each group was divided into two subgroups of 20. In ten out of 20 specimens in each group, monobond plus and Tetric ceram composite resin were applied on the surface. ZPrime Plus and Elite composite were applied on the surfaces of the remaining 10 specimens in each group. Samples were then subjected to shear bond strength test in a universal testing machine until fracture. The mean SBS were calculated and statistically analyzed by two-way ANOVA and T-Test. P

Introduction: A growing body of evidences shows stimulating results on the use of Vaginal Erbium Laser (VEL) for the treatment of genitourinary syndrome of menopause (GSM) and stress urinary incontinence (SUI). However, no data on the duration of laser effects after 6 –12 months are currently available.

ConclusionsLow-level laser therapy (LLLT) and MC application both improved the process of bone remodeling during orthodontic treatment with corticotomy. Still, electrical current therapy promoted a more effective tooth displacement but presented expected root resorption similar to all experimental treatments.Clinical relevanceIt is important to know the effects of minimally invasive therapies on cellular and molecular elements involved in the bone remodeling of orthodontic treatment associated with corticotomy surgery, in order to reduce the adverse effects in the use of this technique and to establish a safer clinical routine.

AbstractThe aim of this study was to evaluate the effects of low-level laser therapy using the gallium arsenide laser (λ = 830 nm) on the articular cartilage (AC) organization from knee joint in an experimental model of microcrystalline arthritis in adult male Wistar rats. Seventy-two animals were divided into three groups: A (control), B (induced arthritis), and C (induced arthritis + laser therapy). The arthri tis was induced in the right knee using 2 mg of Na4P2O7 in 0.5  mL of saline solution. The treatments were daily applied in the patellar region of the right knee after 48 h ...

AbstractReview effectiveness of low-level laser therapy (LLLT) in the curative treatment of oral mucositis (OM) in patients receiving cancer therapy. A systematic review with meta-analysis was performed using Medline, Embase, and Cochrane Library databases according to PRISMA guidelines, to identify randomized controlled trials (RCT) on OM in patients during and/or after cancer therapy and in which the therapeutic approach was LLLT, with wavelengths between 632 and 970  nm. We considered grade of OM as a dichotomous variable (such as an improvement or not in severe OM on the seventh day of therapy), with the analysis ...

CONCLUSIONS: Vaginal laser therapy has shown potential and demonstrated its safety for use in urology as either a complementary or alternative treatment to existing treatment options, such as topical hormonal therapies, pelvic floor exercises or surgical procedures. It is necessary to define it as separate from aesthetic procedures. PMID: 30721329 [PubMed - as supplied by publisher]

Authors: Zhang Y, Zheng X, Chen Z, Lu L Abstract BACKGROUND: Treatment of melasma is challenging because its pathogenesis is unclear and it is prone to recurrence. We performed a meta-analysis to evaluate the efficacy and safety of laser and laser compound therapy for melasma. METHODS: We searched the Cochrane, Embase, and Medline databases for all relevant studies published from inception to July 2018. All randomized controlled trials of melasma describing treatment with lasers or laser compound therapy were included. RESULTS: A total of 346 patients were enrolled in nine RCT studies. Laser therapy and las...

AbstractSkin aging is a complex biological process induced by intrinsic and extrinsic factors which is characterized by clinical and cellular changes, especially dermal fibroblasts. It is possible that, some procedures, such as low-level laser therapy (LLLT), could decelerate this process. To test this hypothesis, this study evaluated the in vitro LLLT on dermal fibroblast cell line (HFF-1) with premature senescence H2O2-induced. HFF-1 cells were cultured in standardized conditions, and initially H2O2 exposed at different concentrations. Fibroblasts were also just exposed at different LLLT (660  nm) doses. From these ...

Coats disease is a rare pediatric retinal vascular disorder, usually isolated to 1 eye, that can cause severe vision loss or even a blind painful eye when untreated or treated late. In the past decade or so, management has been focused on multimodal imaging modalities (ie, optical coherence tomography [OCT] and fluorescein angiography) and combination therapy (ie, cryotherapy, laser therapy combined with steroid medication and anti –vascular endothelial growth factor agents) in an effort to improve vision. Assessing recent management and outcome trends in Coats disease is difficult, because the disease is uncommon, a...
