Objective: The aim of this study was to evaluate the levels of salivary biomarkers IL-1β, IL-10, RANK, OPG, MMP-2, TG-β and TNF-α in individuals with diagnosis of peri-implant mucositis in the absence or presence of periodontal and peri-implant maintenance therapy (TMPP) over 5 years.

Material And Methods: Eighty individuals diagnosed with peri-implant mucositis were divided into two groups: one group that underwent periodontal and peri-implant regularly maintenance therapy, called GTP (n=39), and a second group that received no regular maintenance GNTP (n=41). Each participant underwent a complete periodontal and peri-implant clinical examination.

Background: The most accurate data help to minimize possible mistakes on a patient´s evaluation, as more robust findings are necessary to establish a correct diagnosis, prognosis and, consequently, better treatment.

Purpose: Could biomarker levels in the saliva help to distinguish between healthy implants and implants with peri-implant disease?

Materials And Methods: An electronic database search of Pubmed/MEDLINE, Web of Science, the Cochrane Library, OVID and Scielo was performed. The articles and abstracts identified were considered relevant if they compared cytokine levels in saliva from patients with healthy implants to those in saliva from patients with untreated peri-implantitis.

Aim: The aim of the present study was to assess the periodontal condition and sensitivity of second mandibular molars after the extraction of the adjacent third molar, while also assessing the quality of life of the patients.

Materials And Methods: Twenty-three healthy patients were assessed in terms of probing depth, gingival height, gingival thickness, dental sensitivity, plaque index and bleeding on probing (adjacent second mandibular molar), before the surgical procedure, as well as 60 and 180 days after the surgery. The following data were also recorded and measured: the position and size of the impacted teeth; the size of the alveoli after surgery and the quality of life of the patient.
