The following consensus report is based on four background reviews. The frequency of maintenance visits is based on patient risk indicators, homecare compliance and prosthetic design. Generally, a 6‐month visit interval or shorter is preferred. At these visits, peri‐implant probing, assessment of bleeding on probing and, if warranted, a radiographic examination is performed. Diagnosis of peri‐implant mucositis requires: (i) bleeding or suppuration on gentle probing with or without increased probing depth compared with previous examinations; and (ii) no bone loss beyond crestal bone level changes resulting from initial bone remodelling. Diagnosis of peri‐implantitis requires: (i) bleeding and/or suppuration on gentle probing; (ii) an increased probing depth compared with previous examinations; and (iii) bone loss beyond crestal bone level changes resulting from initial bone remodelling. If diagnosis of disease is established, the inflammation should be resolved. Non‐surgical therapy is always the first choice. Access and motivation for optimal oral hygiene are key. The patient should have a course of mechanical therapy and, if a smoker, be encouraged not to smoke. Non‐surgical mechanical therapy and oral hygiene reinforcement are useful in treating peri‐implant mucositis. Power‐driven subgingival air‐polishing devices, Er: YAG lasers, metal curettes or ultrasonic curettes with or without plastic sleeves can be used to treat peri‐implantitis. Such treatment usually provides clinical improvements such as reduced bleeding tendency, and in some cases a pocket‐depth reduction of ≤ 1 mm. In advanced cases, however, complete resolution of the disease is unlikely.

Background: The purpose was to compare patient-centered outcomes, early wound healing, and postoperative complications at palatal donor area of subepithelial connective tissue grafts (CTG) between cyanoacrylates tissue adhesives and polytetrafluoroethylene (PTFE) sutures. Methods:Thirty-six patients who required harvesting of CTG were enrolled in this randomized clinical trial and assigned to one of two groups. In the "suture" group, wound closure was achieved with standardized continuous interlocking 6-0 PTFE sutures, while in the "cyanoacrylate" group, a high viscosity blend of n-butyl and 2octyl cyanoacrylate was applied until hemostasis was achieved. The primary outcome was the discomfort (eating, speaking, etc.) from the donor site during the first postoperative week; this was self-reported on a visual analog scale questionnaire. Secondary outcomes were the time required for suture placement or cyanoacrylate application, patient self-reported pain on the first day and the first week after surgery, the analgesic intake and the modified early-wound healing index (MEHI). Results:The median value of discomfort was 1.49 in the "suture" group and 1.86 in the "cyanoacrylate" (P = 0.56). The mean time required for suture placement was 7.31 minutes and for cyanoacrylate application 2.16 minutes (P < 0.0001). No statistically significant differences were found between the two methods in reported pain level, analgesic intake, and MEHI. Conclusions:Cyanoacrylate performs similarly to sutures and can be used for wound closure of the donor site of CTG. The application was about 5 minutes faster than conventional suture placement, reducing the total time of the surgical procedure.

Periodontal diseases are pathological processes resulting from infections and inflammation affecting the periodontium or the tissue surrounding and supporting the teeth. Pathogenic bacteria living in complex biofilms initiate and perpetuate this disease in susceptible hosts. In some cases, broad-spectrum antibiotic therapy has been a treatment of choice to control bacterial infection. However, increasing antibiotic resistance among periodontal pathogens has become a significant challenge when treating periodontal diseases. Thanks to the improved understanding of the pathogenesis of periodontal disease, which involves the host immune response, and the importance of the human microbiome, the primary goal of periodontal therapy has shifted, in recent years, to the restoration of homeostasis in oral microbiota and its harmonious balance with the host periodontal tissues. This shift in therapeutic goals and the drug resistance challenge call for alternative approaches to antibiotic therapy that indiscriminately eliminate harmful or beneficial bacteria. In this review, we summarize the recent advancement of alternative methods and new compounds that offer promising potential for the treatment and prevention of periodontal disease. Agents that target biofilm formation, bacterial quorum-sensing systems and other virulence factors have been reviewed. New and exciting microbiome approaches, such as oral microbiota replacement therapy and probiotic therapy for periodontal disease, are also discussed.

Introduction: Rates of periodontal disease and tooth loss are increased in individuals with rheumatoid arthritis (RA). Understanding factors that contribute to the increased burden of periodontal disease in RA is critical to improving oral health and arthritis outcomes. Objectives: To determine the perceptions held by people with RA relating to their oral health, to identify patient-centered priorities for oral health research, and to inform optimal strategies for delivering oral health knowledge. Methods: Semistructured interviews were conducted with patients with RA. Recorded interview transcripts were iteratively reviewed to reveal surface and latent meaning and to code for themes. Constructs were considered saturated when no new themes were identified in subsequent interviews. We report themes with representative quotes. Results: Interviews were conducted with 11 individuals with RA (10 women [91%]; mean age, 68 y), all of whom were taking RA medication. Interviews averaged 19 min (range, 8 to 31 min) and were mostly conducted face-to-face. Three overall themes were identified: 1) knowledge about arthritis and oral health links; 2) oral health care in RA is complicated, both in personal hygiene practices and in professional oral care; and 3) poor oral health is a source of shame. Participants preferred to receive oral health education from their rheumatologists or dentists. Conclusions: People with RA have unique oral health perceptions and experience significant challenges with oral health care due to their arthritis. Adapting oral hygiene recommendations and professional oral care delivery to the needs of those with arthritis are patient priorities and are required to improve satisfaction regarding their oral health. Knowledge Translation Statement: Patients living with long-standing rheumatoid arthritis described poor oral health–related quality of life and multiple challenges with maintaining optimal oral health. Study findings indicate a need for educational materials addressing oral health maintenance for patients with rheumatic diseases and their providers.
