The distinct ability of the gingival and periodontal ligament fibroblasts to secrete MIP-1alpha, SDF-1, and IL-6 emphasizes that these cells may differently contribute to the balance of cytokines in the LPS-challenged periodontium.

The gingival recession was assessed in 380 adult individuals aged more than 20 years and comprised both subjects being treated and looking for treatment at Bauru Dental School. Clinical evaluation was conducted by a single examiner in all teeth and involved analysis of four dental aspects (mesial, buccal, distal and lingual). The gingival recession was regarded as present whenever more than 1mm of root surface was exposed, and its vertical width was measured in millimeters from the cementoenamel junction to the gingival margin. The recessions were further scored following the criteria suggested by Miller in 1985. Gingival recession was observed in at least one dental surface in about 89% of the individuals analyzed. The prevalence, extension and severity of this clinical aspect increased with age. Class I recessions were the most frequent, yet there was a gradual increase of Class III and IV recessions as older subjects were evaluated. The mandibular teeth displayed more surfaces with gingival recession than the maxillary teeth and the mandibular incisors were the most affected teeth. Such high prevalence of gingival recession in adult patients demonstrates that dental professionals should provide attention to the clinical relevance of such alterations, as well as to the diagnosis of the etiologic factors.

This systematic review confirmed that implant therapy can be successfully used in patients with a diagnosis of periodontitis who underwent proper therapy and regular periodontal maintenance. Residual pockets, non-attendance to the periodontal maintenance program, and smoking were considered to be negative factors for the long-term implant outcomes.

This study added important clinical and histological data to contribute in the decision-making process between indication of FGG or ADM.

The aim of this systematic literature review was to evaluate which type of periodontal preventive and therapeutic approaches presents superior outcomes in patients with Down syndrome (DS). Studies reporting different methods of periodontal care from DS patients were considered eligible. Included clinical studies should indicate at least two periodontal parameters in different periods of assessment. Screening of the articles, data extraction and quality assessment were conducted independently and in duplicate. Electronic search according to the PICO search, with both Key-words and MESH terms were conducted in MEDLINE, EMBASE and CENTRAL databases until March 2016. Manual search was conducted in four journals, namely Journal of Periodontology, Journal of Clinical Periodontology, Journal of Periodontal Research and Special Care in Dentistry and their electronic databases were searched. Electronic and manual search resulted in 763 papers, and of them 744 were excluded after title/abstract assessment. The full text of 19 potentially eligible publications was screened and 9 studies met inclusion criteria. The results demonstrated the importance to introduce youngest DS patients in preventive programs, as well as participation of parents, caregivers or institutional attendants in supervising/performing oral hygiene. In studies with higher frequency of attendance, all age groups presented superior preventive and therapeutic results, irrespective of the therapeutic approach used (surgical/nonsurgical/periodontal care program). The important factors for reducing periodontal parameters were the frequency of the appointments and association with chlorhexidine/plaque disclosing agents as adjuvant treatment. This systematic review demonstrated that early introduction in periodontal care, participation of parents/caregivers/institutional attendants, frequency of attendance and association with chemical adjuvants (independently of the periodontal treatment adopted) seems to improve periodontal outcomes in preventive and periodontal treatment of DS patients.
