RESUMEN
The aim of this review was to assess the contribution of herpesviruses in the subgingival oral biofilm in the progression of periodontal and peri-implant diseases in systemically healthy individuals. The literature review was customized to summarize the pertinent information for the following reasons: (1) A systematic review regarding the role of herpesviruses in the etiopathogenesis of periodontal disease has recently been published; and (2) a limited number of studies have assessed the association of herpesviruses with peri-implant diseases. To date, five observational studies have assessed the presence of herpesviruses in the subgingival oral biofilm of individuals with peri-implant diseases. In these studies, dental implants were in place for up to approximately 8 years. In two studies, human cytomegalovirus (HCMV) was more often isolated from the peri-implant sulci of sites with than without peri-implantitis. In one study, a low prevalence of HCMV compared with Epstein-Barr virus (EBV) was associated with the progression of peri-implantitis. In previous studies, the presence of EBV in the subgingival oral biofilm was associated with the onset of peri-implantitis and peri-implant mucositis, respectively. Major limitations of the studies assessed were the absence of blinding and lack of power analysis for sample size estimation. In conclusion, the presence of herpesviruses in the periodontal and peri-implant subgingival oral biofilm is an indicator of periodontal and peri-implant diseases in systemically healthy individuals; however, further studies with a statistically justified sample-size are needed to understand and refine this association.

BACKGROUND: To assess the impact of scaling and root planing (SRP) with and without adjunct photodynamic therapy (PDT) in the treatment of periodontal disease (PD) in hyperglycemic patients. METHODS: Databases (MEDLINE, EMBASE; and CENTRAL) were searched up to December 2017. The addressed PICO question was: "What is the effectiveness of adjunctive PDT to non-surgical periodontal treatment by means of clinical periodontal and glycemic parameters in hyperglycemic patients?" RESULTS: Four clinical trials and 1 experimental study were included. Energy fluence, power output, power density and duration of irradiation were 2.79â¯J per square centimeters (Jâ¯cm-2), 150 milliwatts (mW), 428 milliwatts per square centimeters (mW/cm2) and 133â¯s (s) respectively. All studies reporting clinical periodontal and metabolic parameters, showed that aPDT was effective in the treatment of periodontal inflammation in hyperglycemic patients at follow-up. When compared with SRP alone, none of the studies showed additional benefits of PDT as compared to SRP alone at follow up. Three studies showed no influence of SRP with or without aPDT on HbA1c levels. One study showed a significant reduction of HbA1c levels in adjunctive aPDT as compared to SRP alone at follow-up. CONCLUSION: It remains debatable whether adjunctive PDT as compared to SRP is effective in the treatment of periodontal inflammation and reduction of HbA1c levels in hyperglycemic patients.
