Treatment of amalgam tattoo with an Er,Cr:YSGG laser

Case Report Journal of Investigative and Clinical Dentistry, Volume 1, Issue 1, 2010, Pages 50-54

Abstract

Amalgam tattoos are common, asymptomatic, pigmented oral lesions that clinically exist as isolated, blue, gray, or black macules on the gingival, buccal, and alveolar mucosae, the palate, and/or the tongue. In this case report, the successful use of an erbium, chromium-doped:yttrium, scandium, gallium, and garnet laser for the removal of an amalgam tattoo is explained. A 46-year-old man is presented with a half decade history of an amalgam tattoo on his left maxillary premolar-molar gingiva. Depigmentation procedure was performed under topical anesthesia with the use of an erbium, chromium-doped:yttrium, scandium, gallium, and garnet laser at 2 W in the soft tissue pulsed mode for 10 min. The pigmented tissue was completely removed. The de-epithelialization area healed completely on the 10th day after treatment. The period of healing was uneventful. The amalgam tattoo was completely removed with erbium, chromium-doped:yttrium, scandium, gallium, and garnet laser, and the treated area healed without any adverse effect.

Clinical Application of Stereolithographic Surgical Guide With a Handpiece Guidance Apparatus: A Case Report.

Case Report Journal of Oral Implantology, Volume 38, Issue 5, 2012, Pages 603-609

Abstract

The success of implant-supported restorations depends on the treatment planning and the transfer of planning through the surgical field. Recently, new computer-aided design and manufacturing (CAD/CAM) techniques, such as stereolithographic (SLA) rapid prototyping, have been developed to fabricate surgical guides to improve the precision of implant placement. The objective of the present case is to introduce a recently developed SLA surgical guide system into the rehabilitation of a 62-year-old male patient with mandibular edentulism. After obtaining a cone-beam computerized tomography (CBCT) scan of the mandible with a radiographic template, the images were transferred into a 3-dimensional (3D) image-based software for implant planning. The StentCad Beyond SLA surgical guide system, which is a combination of a currently used surgical template with pilot hollows and a surgical handpiece guidance apparatus, was designed to transfer a preoperatively defined implant position onto the surgical site without any drill-surgical guide contact. For the fabrication of this system, a surgical handpiece was scanned by a laser optical scanner and a mucosa-supported surgical guide was designed according to the patient's 3D model, which was attained from the CBCT images. Four dental implants were inserted through the SLA surgical guide system by a torque-controlled surgical handpiece to the interforaminal region via a flapless surgical procedure. Implants were assessed 3 months after surgery, and an implant-retained mandibular overdenture was fabricated. The present case emphasizes that CAD/CAM SLA surgical guides, along with CBCT images and scanning data, may help clinicians plan and place dental implants.

Clinical evaluation of Er,Cr:YSGG and GaAlAs laser therapy for treating dentine hypersensitivity: A randomized controlled clinical trial.

Original Article Journal of Dentistry, Volume 39, Issue 3, 2010, Pages 249-254

Abstract

Objective The advent of dental lasers has raised another possible treatment option for dentine hypersensitivity (DH) and has become a research interest in the last decades. The aim of this randomized, controlled, double-blind, split mouth, clinical study was to evaluate and compare the desensitizing effects of erbium, chromium-doped:yttrium, scandium, gallium and garnet (Er,Cr:YSGG) to galium–aluminium–arsenide (GaAlAs) laser on DH. Methods Fifty-one patients participated in this study for a total of 174 teeth. DH was assessed for all groups with a visual analog scale. For each patient, the teeth were randomized to three groups. In the diode laser group, sensitive teeth were irradiated with the GaAlAs laser at 8.5 J/cm2 energy density. In the Er,Cr:YSGG laser group, sensitive teeth were irradiated with Er,Cr:YSGG laser in the hard tissue mode using a none-contact probe at an energy level of 0.25 W and repetition rate of 20 Hz, 0% water and 10% air. In the control group no treatment was performed. Treatment time was 60 s for GaAlAs laser and 30 s for Er,Cr:YSGG laser. Results When compared with the control group and baseline data, in both laser groups, laser irradiation provided a desensitizing effect immediately after treatment and this effect was maintained throughout the study (p < 0.05). No significant differences between Er,Cr:YSGG and GaAlAs laser groups were found at any follow-up examination (p > 0.05). Conclusion Based on these findings, it may be concluded that both Er,Cr:YSGG and GaAlAs lasers were effective in the treatment of DH following a single application.

Long-Term Effect of Diode Laser Irradiation Compared to Sodium Fluoride Varnish in the Treatment of Dentine Hypersensitivity in Periodontal Maintenance Patients: A Randomized Controlled Clinical Study

Original Article Photomedicine and Laser Surgery, Volume 29, Issue 11, 2011, Pages 721-725

Abstract

Objective: The aim of this clinical study was to evaluate and compare the desensitizing effects of a gallium–aluminum–arsenide (GaAlAs) laser and sodium fluoride (NaF) varnish on dentine hypersensitivity (DH) in periodontal maintenance patients. Background data: The use of lasers opens a new dimension in the treatment of DH. Methods: Forty-eight patients with 244 teeth affected by DH were included in the trial. To be included in the study, the subjects had to have 4 or more hypersensitive teeth at different quadrants. Selected teeth were randomly assigned to a GaAlAs laser group, placebo laser group, NaF varnish group, or a placebo NaF varnish group. Laser therapy was performed at 8.5?J/cm2 energy density. In the placebo laser group, the same laser without laser emission was used. In the NaF varnish group, the varnish was painted at the cervical region of the teeth. In the placebo NaF varnish group, the same treatment procedures were performed with a saline solution. DH was assessed with a visual analog scale (VAS); immediately, at 1 week, and at 1, 3, and 6 months after treatments. Intra-group time-dependent data were analyzed by Friedman's test, and Wilcoxon's rank sum test was used to evaluate the differences within groups. Results: GaAlAs laser and NaF varnish treatments resulted in a significant reduction in the VAS scores immediately after treatments that were maintained throughout the study when compared to the baseline and placebo treatments. In the NaF group, there was a significant increase in the VAS scores at 3 and 6 months compared to at 1 week and 1 month. The placebo treatments showed no significant changes in VAS scores throughout the study period. Conclusions: Within the limits of the study, GaAlAs laser irradiation was effective in the treatment of DH, and it is a more comfortable and faster procedure than traditional DH treatment.

Effect of alloy recasting on the color of opaque porcelain applied on different dental alloy systems.

Original Article The Journal of Prosthetic Dentistry, Volume 108, Issue 6, 2012, Pages 362-369

Abstract

Statement of problem The effect of different proportions of recast dental alloys on the color of overlying opaque porcelain (OP) is unknown. Purpose The purpose of this study was to compare the color of OP applied on 2 different proportions (50% and 100%) of recast alloys with the color of commercially available shade tabs of OP. Material and methods Six different metal alloy systems (2 base: Metalloy CC, Cr-Co [B-MCC]; Heraenium NA, Ni-Cr [B-HNA]; 3 noble: Cerapall 2, Pd-Au [N-CP2]; Triumph, Pd-Ag [N-T]; V-Deltaloy, Au-Pd [N-VD]; and 1 high-noble: V-Gnathos Plus, Au-Pt [HN-GP]) were selected for the fabrication of disk-shaped specimens (10 mm in diameter, 1 mm in thickness). Each alloy was divided into 2 subgroups: 50% new alloy with 50% recast alloy (n=3) and 100% recast alloy (n=3). OP (B1) was applied (0.1 mm) to all specimens. The color coordinates (L*, a*, b*) of each specimen and the corresponding commercially available OP shade tab (control) were measured with a spectroradiometer, and color differences between specimens and control group were calculated. Data were statistically analyzed (2-way ANOVA, Ryan-Einot-Gabriel-Welsch multiple range test, ?=.05). Results For each alloy, ?L*(Lcontrol-Lrecastalloy) values for the 2 subgroups were not statistically different from each other. The ?a* and ?b* of different proportions of N-CP2, B-HNA, N-VD, and HN-GP were not statistically different within the alloys. However, the a* values of 100% recast N-T and B-MCC were significantly closer to the a* values of the control group, and the b* values of 50% recast B-MCC were significantly closer to the b* values of the control group (P<.05). Delta Econtrol-recast alloy values for different proportions of alloys were not statistically different. However, color differences did not meet the criterion of clinical acceptability (?E=3.46). Conclusions According to the results of this study, the different proportions (50% and 100%) of recast alloys used have similar effects on the color of OP. Differences between the final color of OP on the recast alloys used and the color of OP shade guide tabs did not meet the criterion of clinical acceptability considered in this study.

Evaluation of staining susceptibility of resin artificial teeth and stain removal efficacy of denture cleansers

Original Article Acta Odontologica Scandinavica, Volume 72, Issue 8, 2014, Pages 811-818

Abstract

Objective. To assess the staining susceptibility of four acrylic resin (Ivostar, SR Vivodent PE, Major Dent, Integral) and a nanocomposite resin (Veracia) artificial teeth and to evaluate the stain removal efficacy of denture cleansers. Materials and methods. Sixty maxillary incisors of each brand (total = 300) were divided into three groups according to staining solution as coffee, red wine and tea. Baseline color measurements were performed with a spectrophotometer. Specimens were immersed in staining solutions for 14 h (2 h × 7 days) and then second color measurements were performed. Each group was further divided into four sub-groups according to denture cleanser as Corega tabs, Fittydent, NaOCl (0.5%) and distilled water (control) (n = 5). Specimens were immersed in denture cleansers for 8 h and third color measurements were made. Thus, the weekly simulation period was completed. This cycle was repeated 12 times to simulate a 3-month time period and measurements were performed at the end of the 4th, 8th and 12th cycles. ?E values were calculated and data were analyzed with 3-way repeated measures ANOVA and Bonferroni tests. Results. Significant color differences were found among the teeth and staining solutions, but all of the color differences were in the clinically acceptable range (?E < 5.5). Integral showed the highest ?E values for all solutions, while Ivostar and Vivodent demonstrated the lowest ?E values for red wine and tea solutions. There was no significant difference among the denture cleansers in terms of stain removal efficacy. Conclusions. Cross-linked acrylic (Integral) and nanocomposite (Veracia) resin teeth were more susceptible to staining. Denture cleansers were efficient on stain removal from artificial teeth.

The Effect of Er,Cr:YSGG Laser Application on the Micropush-Out Bond Strength of Fiber Posts to Resin Core Material.

Original Article Photomedicine and Laser Surgery, Volume 32, Issue 10, 2014, Pages 574-581

Abstract

Objective: The aim of this study was to compare the effects of erbium, chromium: yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser application to different surface treatments on the micropush-out bond strengths between glass and quartz fiber posts and composite resin core material. Background data: Different types of lasers have been used as an alternative to airborne particle abrasion and other surface treatment methods to enhance the bond strength of dental materials. However, there is no study regarding the use of Er,Cr:YSGG laser as a surface treatment method for fiber posts in order to improve the bond strength. Materials and methods: Ninety-six quartz and 96 glass fiber posts with a coronal diameter of 1.8?mm were randomly divided into eight groups according the surface treatments applied. Gr 1 (control, no surface treatment), Gr 2 (sandblasting with 50?µm Al2O3), Gr 3 (9 % hydrofluoric acid for 1?min), Gr 4 (24% H2O2 for 1?min), Gr 5 (CH2Cl2 for 1?min), Gr 6 (1?W), Gr 7 (1.5?W), and Gr 8 (2?W) Er,Cr:YSGG laser irradiation. The resin core material was applied to each group, and then 1?mm thick discs (n=12) were obtained for the micropush-out test. Data were statistically analyzed. Results: For the quartz fiber post group, all surface treatments showed significantly higher micropush-out bond strengths than the control group (p<0.05), except for the 2?W Er,Cr:YSGG laser group. For the glass fiber post group, H2O2, CH2Cl2, Al2O3, and laser application (1?W, 1.5?W) (p<0.05) enhanced the bond strength between the post and core material. However, the hydroflouric acid group showed the lowest bond strength values. Conclusions: The type of post and surface treatment might affect the bond strength between fiber posts and resin core material; 1?W and 1.5?W Er,Cr:YSGG laser application improved adhesion at the post/core interface.

Original Article Journal of Dentistry and Oral Care, Volume 1, Issue 4, 2015, Pages 1-4

Abstract

Objective: to assess the color stability of artificial teeth after immersion in different staining solutions and to determine the effect humic acid on removing stain from teeth. Background: Old denture wearer needs effective, easy-use and safe denture-cleaning material. Material and Methods: Sixty maxillary incisors were divided into the three groups according to staining solution as tea (T), cherry juice (CJ) and cola (C). Baseline color measurements were performed with a spectrophotometer. Specimens were immersedin a staining solutions for 14 h (2 h _ 7 days) and then second color measurements were performed. Each group was further divided into four sub-groups according to denture cleanser as Corsodyl (Cr), Corega tablet (Ct), humic acid (H) and distilled water (W) (n=5). Specimens were immersed in denture cleansers for 8h and third color measurements were made. Thus, the weekly simulation period was completed. This cycle was repeated 12 times to simulate a 3-month time period and measurements were performed. Color differences were calculated and data were analyzed with 2-way repeated measures ANOVA and Tukey tests. Results: The highest color difference after staining was noted in T. After the 12-times repeated immersion beverage and cleanser cycle, discoloration of teeth stained in beverages and cleaned with different solutionswas demonstrated. H and W were more effective than others for the teeth stained in T and Cj. However there was no difference among the cleaning solutions for teeth stained in C. Conclusions: Humic acid could be used as an alternative “natural” solution for denture-cleaning agent.

Farklı Kompozit Rezinlerin Translusensi Özelliklerinin Karşılaştırılması

Original Article EÜ Dişhek Fak Derg, Volume 36, Issue 3, 2015, Pages 128-131

Abstract

Objectives: This study aimed to compare the translucency characteristics of different shades of 5 composites. Methods: Seven resin discs were prepared from each composite (Grandio, Gradia Direct, Clearfil Majesty Esthetic, Ceram-X Mono, Filtek Z250) and shade (A1, A2, A3). Baseline CIE L*a*b* color coordinates of specimens were measured in a viewing booth with D65 illumination by spectrophotometer (Easyshade Compact, Vita). The translucency parameter was calculated for each specimen. Results were analyzed statistically. Results: Grandio and Gradia were significantly more translucent than Clearfil Majesty Esthetic, Ceram-X Mono and Filtek Z250 for A1 shade. For A2 shade, TP values of Grandio, Gradia and Clearfil Majesty Esthetic were statistically higher than Filtek Z250 and Ceram-X Mono. For A3 shade, Grandio was statistically the most translucent resin among all composites. There was no statistical difference between TP values of Clearfil Majesty Esthetic, Gradia and they were significantly more translucent than Filtek Z250 and Ceram-X Mono for A3 shade (p<0.05). TP values of A3 shade of Grandio were higher than A1 shade. Conclusion: Translucency characteristics of composites may be influenced by the brand in each shade. Information on the relative translucencies of different composites can be useful in selecting the correct composite for the achievement of optimal esthetic results.

Clinical Evaluation of the Er,Cr:YSGG Laser Therapy in the Treatment of Denture-Related Traumatic Ulcerations: A Randomized Controlled Clinical Study.

Original Article Photomedicine and Laser Surgery, Volume 33, Issue 4, 2015, Pages 224-229

Abstract

Objective: The aim of this study was to evaluate the efficacy of Er,Cr:YSGG laser irradiation in reducing pain and on healing rate of traumatic ulcerations (TU) during a 2-week period after placement of new complete dentures. Background data: Denture-related TU are painful, and result in patient discomfort. Lasers are used in the treatment of different kinds of mucosal lesions; however, there are no published data available concerning the clinical outcome of the use of laser therapy in the treatment of TU. Materials and methods: Thirty edentulous patients with newly fabricated complete dentures who subsequently developed one or more pairs of TU participated in this study. For each patient, ulcerations were randomly assigned to the test and control groups. In the test group, ulcerations were irradiated with Er,Cr:YSGG laser. In the control group, the same laser without laser emission was used. Pain was assessed with a visual analog scale (VAS). Healing of ulcerations (HU) was graded by a clinician. Results: In the test group, laser irradiation provided significantly reduced pain immediately after treatment, and provided a significant healing effect 1 day after treatment, and these effects were maintained throughout the study. In the control group, baseline VAS scores were not statistically significant at baseline and 1 day after treatment, and HU scores were statistically significant 3, 7, and 14 days after treatment. Intergroup comparisons revealed that the differences in VAS and HU scores were statistically significant for all time periods after treatment, except for day 14. Conclusions: Based on these findings, it may be concluded that Er,Cr:YSGG laser is effective in the treatment of TU.

The effect of home bleaching agents on the surface roughness of five different composite resins: A SEM evaluation

Original Article Scanning, Volume 38, Issue 3, 2016, Pages 277-283

Abstract

The aim of this study was to investigate the effect of hydrogen peroxide (HP) and carbamide peroxide (CP) on the surface roughness of five different composite resins using profilometer and scanning electron microscope (SEM). Thirty-six specimens (1?mm thick, 10?mm in diameter) of five composite resins were fabricated. Each composite group was equally divided into three subgroups as control, CP and HP. In control group, specimens were stored in daily refreshed distilled water during the 14-day testing period. In other groups, 10% HP (Opalescence Treswhite) and 10% CP (Opalescence PF) were applied and surface roughness values (Ra) of each specimen were measured with a profilometer at the end of 14 days. Additionally, SEM analysis was performed to evaluate the surface deformations of composite resins. Data were analyzed with Kruskal-Wallis and Mann-Whitney U tests. Ra values of composite groups exposed to bleaching agents were statistically higher than control group (p?<?0.05). There was no significant difference between Ra values after HP and CP application within each composite group while SEM micrographs showed higher surface alterations at HP group compared to CP. Among the composite resins tested, Ceram-X Mono revealed the lowest Ra values after CP and HP applications as seen at SEM images. Home bleaching agents increased the surface roughness of all composites. Except CP applied Ceram-X mono specimens, Ra values of all composite resins evaluated in this study exceeded the critical limit of 0.2?µm. Ceram-X mono was the least affected composite material after bleaching application.

Review Cumhuriyet Üniversitesi Diş Hekimligi Fakültesi Dergisi, Volume 11, Issue 2, 2008, Pages 132-139

Abstract

In the dental laboratories, surplus alloys are commonly reused from the initial casting, and with the addition of new alloy, produces other restorations. Recasting may change the chemical composition and microstructure of alloys and thus have an effect on the change of mechanical properties. The results about this subject have indicated that the amounts of the elements, especially Cu, Sn, Zn, Cr and Ti, were decreased; the grain size was increased; the casting defects, principally porosities, and the impurity contents were increased, and the mechanical properties were affected. Since particular metal oxides are critical for adequate adhesion of dental porcelain to metal structure, it is possible that repeated casting of metals could also be detrimental for metal-ceramic bonding. The optimal proportions of new and old alloys are not well known and the effect of reusing dental alloys on mechanical properties has not been completely understood. Before a definitive recommendation can be made for repeatedly using dental alloys, clinically relevant mechanical properties and bond strength of porcelain-to-metal for different alloy systems should be evaluated and considered along with compositional-microstructural analyses and biological properties of the remelted alloys. In this review article, the effects of recasting on mechanical properties of dental alloys and current issues relevant to these properties of recast alloys were presented.

Review Selçuk Üniversitesi Diş Hekimliği Fakültesi Dergisi, Volume 17, Issue 2, 2008, Pages 155-163

Abstract

For economic reasons, dental alloys from the casting surplus are commonly reused by melting and recasting. It is common practice to include a proportion of new metal with previously cast metal. In this way, components of the alloy lost or damaged in earlier casting procedures may be replenished. The biocompatibility of cast alloys has been related to the alloy composition, microstructure and also to the elements released from the alloys into the surrounding medium. In this article, the effects of recasting on biologic properties of dental casting alloys and current issues relevant to these properties are presented. The recasting process may change the composition and structure of dental alloys, and degrade the corrosion performance. The results about the recasted alloys indicated that especially the gold, chromium and titanium decreased; the impurity content and their segregation to the grain boundaries increased; the grain size increased; the casting defects increased and the corrosion resistance decreased. It was revealed that the alloy types and the elements of alloys become affected to a different degree when the alloy was recasted, and the recasting process markedly increased the element release and cytotoxicity of base metal alloys. An exact number of recasting process and percentage of the recast alloy for permissible recasts of the different alloys are unknown. Further investigation is required to determine the alteration of chemical composition, microstructure, and corrosion behavior for recasted alloys. Recasting of dental alloys, especially the base metal alloys, should be avoided in clinical dentistry until the required data will be completed.

İmplant Diş Hekimliğinde İmmediat ve Konvansiyonel Yükleme Uygulamalarının Karşılaştırılması

Review Turkiye Klinikleri JProsthodont-SpecialTopics, Volume 1, Issue 3, 2015, Pages 42-50

Abstract

Recently, implant dentistry has evolved to a stage that conventional healing time couldn o longer satisfy not only the patients but also health care providers. The advancements in implantd entistry has allowed shortened treatment time by restoring implants earlier. For shortening thet reatment procedures a concept that allows immediate loading of implants have been introduced.I mmediate loading concept is considered to be a better option than delayed loading with their var-i ous advantages such as immediately restoration of function and esthetics. These advantages, how-e ver, may be offset by an increased risk of implant failure. The purpose of the present literaturer eview is to estimate the success of immediate loading by comparing this treatment protocol withc onventional loading with the aid of contemporary studies
