Níveis de nitrito na saliva e no fluido peri-implantar em humanos

by Vieira, Andreia Espíndola

Abstract (Summary)
Nitric oxide has an important effect on host response. However itspotential as a possible diagnostic tool in peri-implant disease has been littlestudied. In this study the nitrite levels in saliva and peri-implant sulcular fluid(PISF) of partially edentulous patients and the possible correlation betweenthese levels and clinical parameters were determined. Twenty four patientswere examined to determine the peri-implant status (healthy or diseased) basedon probing depth (PD), bleeding on probing (BOP) and presence of visibleplaque (VP). Saliva and sulcular fluid (SF) around teeth (internal control) anddental implants were collected and the nitrite levels were evaluated by theGriess method. Nitrite levels in saliva and SF of these patients were comparedand their correlations with clinical parameters were evaluated. Clinical data(BOP and VP) were higher in implants than in matching control teeth, but didnot show significance (pgt;0.05) with the exception of PD. Differences in totalnitrite levels in saliva and SF of healthy and diseased groups were not observed(pgt;0.05). Teeth and implants of healthy or diseased groups did not demonstratestatistical difference regarding nitrite levels (pgt;0.05). Correlation betweenclinical parameters and nitrite levels in saliva or SF was not observed in healthyor diseased groups except for VP in implants of the healthy group (p=0.031, r=-0.72). These results demonstrated similarity between dental sites and implants.The present findings do not allow the use of nitrite as a diagnostic tool for periimplantdisease, in patients with slight inflammation.
