The presence of periodontitis has been hypothesized as a risk factor for several systemic outcomes, including chronic kidney disease (CKD). Therefore, the aim of this study is to evaluate the impact of non-surgical periodontal treatment on CRP levels and quality of life of patients with chronic kidney disease undergoing hemodialysis (HD) in Santa Maria-RS.
C-reactive protein (CRP) has been identified as a possible mediator of the association between periodontitis and various systemic diseases. The presence of periodontitis has been hypothesized as a risk factor for several systemic outcomes, including chronic kidney disease (CKD). Therefore, the aim of this study is to evaluate the impact of non-surgical periodontal treatment on CRP levels and quality of life of patients with chronic kidney disease undergoing hemodialysis (HD) in Santa Maria-RS. A total of 88 patients with severe periodontitis who are on HD therapy will be included in this study. At baseline, periodontal, radiographic, blood test, and quality-of-life questionnaire will be assessed for all patients, after which severe periodontitis will be defined according to the American Association of Periodontology and European Federation of Periodontology. The 88 patients with periodontal disease will be randomized and divided into two groups. One group will receive full mouth non-surgical periodontal treatment (TPNC) and a late treatment group that will receive TPNC only at the end of the study. All patients will receive follow-up of periodontal parameters and blood collection for initial CRP assessment at 3 and 6 months after treatment. Outcome evaluators will be blind to the group the patient belongs to. Patients in the immediate treatment group will receive follow-up oral hygiene instructions and use 0.12% chlorhexidine mouthwash during the first week after treatment.

| effect of periodontal treatment on levels of systemic inflammatory markers | To evaluate the impacts of periodontal treatment on the levels of systemic inflammatory markers such as C-reactive protein, albumin and transferrin saturation. The patients will be submitted to the collection of blood sample in the baseline, 3 and 6 months to obtain the clinical variables. | baseline changes by 6 months follow-up |

| effect of periodontal treatment on oral health-related quality of life | To assess the impacts of periodontal treatment on overall quality of life and oral health that will be assessed using the questionnaire Oral Health Impact Profile (OHIP14) (14 items), in this questionnaire the higher the score, the worse the quality of life is considered. | baseline changes by 6 months follow-up |

Outcome assessors will be blind to the group to which the patient belongs, whether immediate or late.

| postponed treatment | Procedure | Patients allocated to the late treatment group will be assessed at baseline, 3 and 6 months. After the end of the follow-up period, they will receive non-surgical periodontal treatment performed in four sessions. |

| effect of periodontal treatment on overall quality of life | To assess the impacts of periodontal treatment on overall quality of life and oral health that will be assessed using the questionnaire The Short-Form Health Survey (SF-36) (36 items). In this questionnaires, the higher the score, the worse the quality of life is considered. | baseline changes by 6 months follow-up |
| effect of periodontal treatment on overall quality of life and related to kidney disease | o assess the impacts of periodontal treatment on overall quality of life and oral health that will be assessed using the questionnaire Kidney Disease Quality of Life Short Form (KDQOL-SF) (80 items). This scale ranges from 0 to 100, higher values show a better quality of life. | baseline changes by 6 months follow-up |
| effect of periodontal treatment on psychological condition in patients with chronic kidney disease undergoing hemodialysis | ndividuals' psychological condition will be assessed using the Depression - Anxiety - Stress Scale 21 (DASS 21) (21 items).The highest grades in each scale correspond to more negative affective states. | baseline changes by 6 months follow-up |
| effect of periodontal treatment on psychological condition | Individuals' psychological condition will be assessed using the sense of coherence (SOC 13) which proposes to explain successful strategies to cope with stress. For the final score calculation, the items are summed and the result can vary from 13 to 65, where higher scores represent SOC. The the greater the result, the greater the coping capacity. | baseline changes by 6 months follow-up |
