BACKGROUND: Increasing evidence implicates biofilms, consisting of species such as Porphyromonas gingivalis, in the etiology of peri-implantitis. Multiple approaches to ablate biofilms on failing implants have been proposed, include the use of lasers; most recently the Er,Cr:YSGG laser. The purpose of this study is to establish an in-vitro single-species biofilm model on implant surfaces and determine power settings of the Er,Cr:YSGG laser that remove the biofilm while not causing physical damage to the disk...

PURPOSE: To investigate the effects of various surface treatment methods on the shear bond strength of self-adhesive resin cement to a novel CAD/CAM hybrid ceramic material. MATERIALS AND METHODS: A novel hybrid ceramic restorative material (Vita Enamic) was used in this study. Sixty resin block specimens were prepared and separated into six groups for each surface treatment method (n = 10); group 1: control group, no treatment applied; group 2: sandblasted by 30 μm silicate-coated alumina particles (CoJet Sandblasting); group 3: 50 μm Al2 O3 sandblasting; group 4: 10% hydrofluoric acid; group 5: no surface treatment + universal adhesive (3M Single Bond Universal); group 6: 200 mJ, 10 Hz 2W Er,Cr:YSGG laser treatment...

Universal adhesives have been recently introduced for use as self-etch or etch-and-rinse adhesives depending on the dental substrate and clinical condition. However, their bonding effectiveness to laser-irradiated enamel is still not well-known. Thus, the aim of this study was to compare the shear bond strength (SBS) of universal adhesives (Single Bond Universal; Nova Compo-B Plus) applied to Er,Cr:YSGG laser-irradiated enamel with SBS of the same adhesives applied in self-etch and acid-etching modes, respectively...

OBJECTIVE: The purpose of this study was to evaluate the clinical use of an erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser in the management of root furcation involvements. BACKGROUND DATA: It has been suggested that the use of laser radiation within the periodontal pocket may be effective in periodontal treatment. However, very limited data from clinical trials exist directly comparing the use of the Er,Cr:YSGG laser to conventional root planing...

Literature regarding the influence of Er,Cr:YSGG laser pulse frequency with different output power levels on adhesion properties of adhesive resin to lased enamel is limited. Therefore, the aim of the present study was to evaluate the effects of laser pulse frequency (20, 35, and 50 Hz) at two different output power settings (3 and 6 W) of Er,Cr:YSGG on the microtensile bond strength (μTBS) of adhesive resin to enamel. Crowns of 35 intact bovine incisors were embedded into self-cure acrylic resin individually, and then flat enamel surfaces were prepared with 600-grit silicon carbide papers under water cooling...

INTRODUCTION: Alveolar osteitis (AO) is a well-known complication following tooth extraction. Plethora of literature is available regarding its treatment modalities signifying that none of the treatment is as effective as any another treatment. LASER on the other hand, has been used to promote soft tissue healing. MATERIAL AND METHOD: In order to evaluate the effects of laser on healing of AO we undertook a randomized clinical trial. In the trial, sixty patients diagnosed with AO were randomly divided into three groups viz: alvogyl, diode laser and Er:Cr:YSGG laser (erbium chromium yttrium scandium gallium garnet)...

The aim of this in vitro study was to evaluate the effect of using Er,Cr:YSGG laser during in-office tooth bleaching on bovine enamel surface to evaluate the safety of this therapy on tooth tissues. Thirty-six enamel specimens were prepared from bovine incisors and divided into three groups: Group 1 specimens (control) received no bleaching treatment; Group 2 received a conventional in-office bleaching treatment (40 % H2O2); Group 3 received laser-assisted bleaching procedure (40 % H2O2) utilizing an Er,Cr:YSGG laser...

BACKGROUND: Despite considerable improvements in oral health, dental caries continue to be a public health issue. The most frequently used, and universally accepted technique, to remove caries is through mechanical ablation of decayed tissues by means of rotating drills (diamond or tungsten carbide, or both). In the past few decades, the introduction of adhesive filling materials (resin composites) has affected cavity filling procedures by reducing its retention needs, with advantages for dental tissue conservation...

OBJECTIVE AND BACKGROUND: Although several surgical techniques have been reported, no study has yet reported alternative strategies for endodontic treatment of autogenous transplanted teeth. Therefore, the aim of this clinical report is to present the long-term endodontic outcome of a nonvital autogenously transplanted third molar treated with an Er,Cr:YSGG laser and radial firing tips (RFTs). CASE REPORT: Autogenous tooth transplantation can be considered an alternative to restore edentulous areas and, in donor's teeth with complete root formation, root canal treatment should be performed up to 14 days following transplantation...

OBJECTIVE: The aim of this study was to evaluate the influence of laser irradiation on flexural strength, elastic modulus, and surface roughness and morphology of glass fiber posts (GFPs). BACKGROUND DATA: Laser treatment of GFPs has been introduced to improve its adhesion properties. MATERIALS AND METHODS: A total of 40 GFPs were divided into 4 groups according to the irradiation protocol: GC-no irradiation, GYAG-irradiation with erbium:yttrium-aluminum-garnet [Er:YAG], GCR-irradiation with erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG), and GDI-irradiation with diode laser...

The application of laser as a monotherapy has been shown to reduce probing pocket depths and increase clinical attachment levels after treatment of patients suffering from chronic periodontitis. Its controversial use as an adjunct to scaling and root planing (SRP) is discussed. The present study aimed to evaluate the efficacy of adjunctive Er, Cr:YSGG laser application following conventional SRP. A total of 30 patients with chronic periodontitis were enrolled in the study. The quadrants of each patient were allocated to either SRP or SRP + laser...

This study evaluated the effect of Er,Cr:YSGG laser on the root canal dentin after luting a fiber post. Twenty-four bovine teeth roots were prepared using NiTi instruments and filled with Sealer 26 and gutta-percha. Post spaces were prepared and roots were distributed according to dentin treatment (n = 8): 2.5%NaOCl (group control), Er,Cr:YSGG laser (1.5 W, 20 Hz, 20 s) (group test 1) or 2.5%NaOCl + Er,Cr:YSGG laser (group test 2). Fiber posts were luted using adhesive cement (Rely X U200, 3M) and roots were prepared to confocal laser scanning microscopy (CLSM) and scanning electron microscope (SEM)...
