Abstract
An in vitro study was designed to evaluate the effects of photobiomodulation (PBM) with 915-nm diode laser on human gingival fibroblast (HGF) cells under hyperglycemic condition. The HGF cells were cultured in Dulbecco's modified eagle medium (DMEM) medium containing 30 mM glucose concentration for 48 h to mimic the hyperglycemic condition. Subsequently, the cells received three sessions of PBM (915 nm, continuous emission mode, 200 mW, energy density values of 3.2, 6, and 9.2 J/cm2). Twenty-four hours post-irradiation, cell proliferation, expression of interleukin 6 (IL-6), and vascular endothelial growth factor (VEGF) were assessed with MTT and real-time polymerase chain reaction (PCR) tests, respectively. Also, reactive oxygen species (ROS) production was measured using CM-H2DCFDA fluorimetry. No changes were detected in the cell proliferation rate between the high glucose control group and laser-treated cells, while VEGF and IL-6 gene expression levels increased significantly after PBM in the high glucose-treated cells group. ROS level was significantly decreased in the irradiated cells in high-glucose medium compared with the high glucose control group. Our study revealed the inductive role of 915-nm-mediated PBM on VEGF and the inflammatory response while concurrently reducing reactive oxygen species production in HGF cells in hyperglycemic conditions.

Abstract
Photobiomodulation is recognized as an effective method for adjunct therapy in periodontal treatments. our purpose in this study was to investigate the effects of different energy densities of 915nm diode laser on the viability and viability capacity of human gingival fibroblast cells. cell samples were examined in 5 groups, including 4 irradiation groups with low-level diode laser 915nm, 1,2,3,4 J/cm2 , and a control group (no Laser irradiation). Cell viability and viability were measured 1, 3 and 5 days after irradiation by MTT and DAPI assay. Statistical differences between groups at any time were analyzed by one-way ANOVA and a post hoc Turkey's test. The cell viability and viability capacity increased on the third day at an energy density of 3 J/cm2 ; (P-value = 0.007) and the fifth day at energy densities of 2,3 and 4 J/cm2 was recorded compared to the control group (P-value =0.000). Also, a significant decrease in the viability and viability of irradiated cells with an energy density of 1 J/cm2 was found. (P-value =0.033). according to our results, Photobiomodulation with 915nm diode laser has a positive stimulating effect on the viability and viability capacity of human gingival fibroblast cells.

Abstract
This study is focused on comparing the effect of various energy densities and wavelengths of diode lasers on the proliferation of human gingival fibroblast (HGF) cells in vitro. In this study, 204 sample cells were examined in 4 test groups (laser radiation) and 1 control group (non-laser radiation). The proliferation rate of radiated cells with wavelengths of 635, 660, 808 and 980 nm and the densities of 1, 1.5, 2.5 and 4 J cm-2 was measured after 1, 3 and 5 days using the MTT assay. The proliferation rate of human gingival fibroblast (HGF) cells in test groups was increased on day 1 at wavelengths of 635, 808 and 980 nm and on day 3 at the wavelength of 980 nm compared with the control group. Our findings denoted that the photobiomodulation therapy increased the proliferation rate of HGF. The most desirable laser radiation setting, which led to the highest proliferation rate of the cells, included 980 nm wavelength with 1, 1.5 and 4 J cm-2 energy densities and 635 nm wavelength with 4 J cm-2 energy density.

Abstract
OBJECTIVES Osteoblasts are the most important cells in the osseointegration process. Despite years of study on dental Implants, limited studies have discussed the effect of saliva on the adhesion process of osteoblasts to implant surfaces. The aim of this in vitro study was to evaluate the effect of saliva on morphology and differentiation of osteoblasts attached to implant surfaces. MATERIALS AND METHODS Twelve Axiom dental implants were divided into two groups. Implants of the case group were placed in containers, containing saliva, for 40 minutes. Then, all the implants were separately stored in a medium containing MG63 human osteoblasts for a week. Cell morphology and differentiation were assessed using a scanning electron microscope and their alkaline phosphatase (ALP) activity was determined. The t-test was used to compare the two groups. RESULTS Scanning electron microscopic observation of osteoblasts revealed round or square cells with fewer and shorter cellular processes in saliva contaminated samples, whereas elongated, fusiform and well-defined cell processes were seen in the control group. ALP level was significantly lower in case compared to control group (P<0.05). CONCLUSION Saliva contamination alters osteoblast morphology and differentiation and may subsequently interfere with successful osseointegration. Thus, saliva contamination of bone and implant must be prevented or minimized.

Abstract
Considering the high prevalence of preterm birth (PTB) and low birth weight (LBW) and their complications as well as the role played by periodontal disease in their incidence and the lack of any report of periodontal therapy on these problems in Iran, the goal of the present research was to determine the effects of periodontal treatment on PLBW incidence among women with moderate or advanced periodontitis who were referred to Javaheri hospital (2004-2005). This clinical trial research was conducted on 30 pregnant women age ranging from 18-35 years old, with moderate or advanced periodontitis. Fifteen subjects randomly underwent the first phase of periodontal treatment including scaling, root planning and the use of 0.2% chlorhexidine mouth rinse for one week. None of these steps were taken for the controls. After necessary follow ups, the effect of periodontal treatment on birth term and birth weight were analyzed statistically. This research was conducted on 30 subjects, 15 controls and 15 cases in study group. In the control group, the observed rate of PLBW was 26.7% whereas among periodontally treated group, phase I, PLBW infant was not observed (P < 0.05). Infants birth weight were (3059.3-389.7) gms in study group and (3371-394.2) gms in the control group and respectively (P < 0.05). Periodontal therapy, phase I, results in a reduction in PLBW incidence rate. Therefore, the application of such a simple method among periodontally diseased pregnant women is recommended.
