The aim of our study was to obtain similar surface properties and elemental composition to virgin implants after debridement of contaminated titanium implant surfaces covered with debris. Erbium-doped:yttrium, aluminum, and garnet (Er:YAG) laser, erbium, chromium-doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser, curette, and ultrasonic device were applied to contaminated implant surfaces. Scanning electron microscopy (SEM) images were taken, the elemental profile of the surfaces was evaluated with energy dispersive X-ray spectroscopy (EDX), and the surface roughness was analyzed with profilometry. Twenty-eight failed implants and two virgin implants as control were included in the study. The groups were designed accordingly; titanium curette group, ultrasonic scaler with polyetheretherketone (PEEK) tip, Er: YAG very short pulse laser group (100 mu s, 120 mJ/pulse 10 Hz), Er: YAG short-pulse laser group (300 mu s, 120 mJ/pulse, 10 Hz), Er: YAG long-pulse laser group (600 mu s, 120 mJ/pulse, 10 Hz), Er, Cr: YSGG1 laser group (1 W 10 Hz), Er, Cr: YSGG2 laser group (1.5 W, 30 Hz). In each group, four failed implants were debrided for 120 s. When SEM images and EDX findings and profilometry results were evaluated together, Er: YAG long pulse and ultrasonic groups were found to be the most effective for debridement. Furthermore, the two interventions have shown the closest topography of the sandblasted, large grit, acid-etched implant surface (SLA) as seen on virgin implants.

Background: The determination of the impact of risk factors such as smoking in periodontal disease development is of importance to better characterize the disease. However, its impact on host response remains unclear. This study aimed to evaluate the effects of tobacco smoking on GCF levels of neutrophil enzymes (myeloperoxidase (MPO), beta-glucuronidase (BGD), neutrophil elastase (NE) and periodontal parameters in healthy young adults with dental plaque biofilm-induced gingivitis. Methods: The study population consisted of 60 systemically healthy young adults (39 smokers (Sm) and 21 non-smokers (n-Sm)) diagnosed with plaque-induced gingivitis. The periodontal examination consisted of a plaque index (PI); gingival index (GI); probing depth (PD); bleeding on probing (BoP), and clinical attachment level (CAL). GCF MPO, BGD, and NE levels were determined by means of an enzyme-linked immunosorbent assay (ELISA). Results: PI, GI, and BoP were significantly increased in the Sm group (p < 0.05). PD and CAL showed no significant difference between Sm and n-Sm groups (p > 0.05). In GCF, MPO, BGD, and NE levels were significantly increased in Sm group (p < 0.05). NE levels showed a significant correlation with GI and BoP (p < 0.05 for both). Moreover, a positive correlation between BGD and NE levels (p < 0.05) was measured. Conclusions: It may be concluded that, even in young patients, tobacco consumption affects the host's immune response related to gingival inflammation. It is, therefore, mandatory to inform young patients about the risk related to tobacco consumption for their gingival health.

Role of Low-Level Laser Therapy as an Adjunct to Initial Periodontal Treatment in Type 2 Diabetic Patients: A Split-Mouth, Randomized, Controlled Clinical Trial
(Mary Ann Liebert, inc, 2017) Aykol Şahin, Gökçe; Baser, Ulku; Aykol-Sahin, Gokce; Dinccag, Nevin; Issever, Halim; Yalcin, Funda; Periodontoloji / Periodontology
Objective: In this split-mouth clinical trial, we evaluated the clinical benefits of low-level laser therapy (LLLT) as an adjunct to nonsurgical periodontal treatment in patients with type 2 diabetes mellitus (DM). Background data: The impaired wound healing seen in diabetic patients may affect the results of periodontal treatment and may require an additional approach. Materials and methods: In total, 22 chronic periodontitis patients with type 2 DM were included. Applying a split-mouth design, two quadrants were treated with only scaling and root planing (SRP) as the control and those in the other two were treated with SRP + LLLT as the test sites in each patient. An 808nm GaAlAs diode laser was performed in the test sites at the energy density of 4.46 J/cm(2) on days 1, 2, and 7 after SRP. Plaque index (PI), probing depth (PD), bleeding on probing (BOP), and clinical attachment level were measured at baseline and again at 1 and 3 months after treatment. Deep periodontal pockets (PD >= 4mm) were evaluated separately. Results: Test sites showed significant improvement in PI and BOP in deep pockets at the 1-month follow-up period (p < 0.001 and < 0.001, respectively), whereas no difference was found between the control and the test sites in other periodontal parameters. Conclusions: LLLT during periodontal treatment offered minimal short-term additional benefit in deep pocket healing in patients with type 2 DM.
