en پریودنتولوژی Periodontology پژوهشي Research <b> Objective: </b>Interleukin-1 (IL-1 ) is one of the most important cytokines which seems to have an important role in the inflammatory process in gingival and peri-implant tissues. The aim of this split-mouth study was to investigate the relationship between the concentration of IL-1 in gingival crevicular fluid (GCF) and peri-implant crevicular fluid (PICF) and clinical parameters such as plaque index (PI), gingival index (GI), pocket depth (PD) and bone loss (BL). <div>  <b>Materials and Methods:</b> In 32 patients, PICF and GCF samples of 41 implants and 41 contralateral teeth were collected and IL-1 was determined by enzyme-linked immunosorbent assay (ELISA). PI, GI, PD and BL were recorded for each of the samples.<div><b> Result :</b>The positive correlation between the level of IL-1 and PI, GI, PD and BL in both groups was observed (P<0.0001). In similar conditions, the level of IL-1 was greatly higher in PICF than GCF (75.26 pg/ and 45.71 pg/ , respectively) (P=0.001).</div><div><b> Conclusion:</b> The findings of the present study indicated that the level of IL-1 may be an important supplement to clinical findings in measuring the health status of gingival or peri-implant tissues. </div></div><div><hr><p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><b>Source: </b>Journal of Dentistry of Tehran University of Medical Sciences<span style="font-size: 15.5pt line-height: 115% font-family: Verdana, sans-serif color: rgb(250, 250, 250) background-color: rgb(101, 111, 115) background-position: initial initial background-repeat: initial initial"><o:p /></span></p> <p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><a href="http://jdt.tums.ac.ir/index.php/jdt/article/view/587" target="_blank"><font color="#0000ff">Full Text</font></a></p></div> Interleukin-1beta, Gingival Crevicular Fluid, Peri-Implantitis 0 0 http://idai.ir/browse.php?a_code=A-10-32-961&slc_lang=en&sid=1 Siamak Yaghobee 10031947532846004178 10031947532846004178 No Department of Periodontics & Dental Implant Research Center of Tehran University of Medical Sciences, Tehran, Iran Afshin Khorsand 10031947532846004179 10031947532846004179 No Dental Research Center and Department of Periodontics, Tehran University of Medical Sciences, Tehran, Iran ءختلشد Paknejad mpaknejad@sina.tums.ac.ir 10031947532846004180 10031947532846004180 Yes Dental Research Center and Department of Periodontics, Tehran University of Medical Sciences, Tehran, Iran
