Abstract
PURPOSE This study aimed to compare insulin status and dysglycemia (prediabetes/diabetes) of patients with chronic (stage III, grade B) or aggressive periodontitis (stage III, grade C) to that of a healthy population. MATERIALS AND METHODS Patients with chronic (CP, n = 16) or aggressive periodontitis (AP, n = 15) and periodontally healthy controls (n = 32) were recruited. Body mass index was calculated. Glycemia, plasma insulin, glycated hemoglobin, C-reactive protein, and lipid levels were measured in fasting. The Homeostasis Model Assessment was used to calculate the insulin sensitivity (HOMA-%S), the beta-cell function (HOMA-%B), and their hyperbolic product (HOMA-%BxS). RESULTS The CP group showed statistically significantly insulin resistance with a lower HOMA-%S (p = 0.0003) and a reduced HOMA-%BxS (p = 0.049) despite a higher insulin level (p = 0.01) vs the control group, even after BMI adjustment. There was also a trend to dysglycemia (prediabetes/diabetes) in the chronic group. In patients with AP, no abnormalities in insulin status were observed and glycemic levels were comparable with controls. Additionally, patients in both AP and CP groups presented significantly higher CRP levels compared to those of the control group (p = 0.02). CONCLUSION Patients with CP showed reduced insulin sensitivity, increased insulin levels but a reduced %BxS product and a trend to dysglycemia. These abnormalities were not observed in AP.

Abstract
Background: Chronic and aggressive periodontitis were the main forms of periodontitis according to the 1999 classification of periodontal diseases and conditions. Their profile in Congolese patients is still undescribed. Aim: The aim of this study was to compare the profile of chronic periodontitis (ChP) with that of aggressive periodontitis (AgP) in Congolese patients. Materials and Methods: Thirty-two patients with ChP and 20 with AgP who consulted the dental services at any of the four medical centers in Kinshasa, from April 2017 to April 2018, were enrolled in the cross-sectional study. All patients underwent a full mouth examination, including assessment of the probing pocket depth and clinical attachment level at six sites per tooth. Microbial samples were collected in the deepest pocket in the maxilla and the deepest pocket in the mandible. A deoxyribonucleic acid (DNA) analysis was performed using DNA strip technology. Fisher exact test, the chi-square test, the t test, and the Mann–Whitney test were used for the statistical analysis. Results: Patients with AgP were significantly younger than those with ChP (P < 0.001). There was no significant difference in the prevalence of Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, or Prevotella intermedia between the AgP and ChP groups (P > 0.05). Aggregatibacter actinomycetemcomitans was detected in 10% of cases in the AgP group and in none of those in the ChP group (P = 0.143). Conclusion: This study shows that the clinical profiles of ChP and AgP are similar in Congolese patients. There were no microbiological differences between these two forms of periodontitis.

Abstract
OBJECTIVES This pilot study aimed to assess dimensional changes following two different alveolar socket sealing techniques. MATERIAL AND METHODS Twenty-one patients requiring tooth extraction and implant placement were randomly allocated to two different alveolar ridge preservation techniques. In the control group, demineralized bovine bone mineral (DBBM) and a gingival soft tissue punch were used to fill and seal the socket, whereas in the test group, the extraction socket was filled with DBBM and sealed with a hemostatic gelatin sponge. Digitalized impressions were taken before and 6 months after tooth extraction. The comparison was made on horizontal and vertical dimensional changes. RESULTS The mean vertical loss was 0.8 ± 0.6 mm for the control group and 0.7 ± 0.5 mm for the test one. No statistical difference was found between groups for the vertical shrinkage. The horizontal dimensional narrowing of the alveolar socket was respectively 7.1/4.0/2.5 mm at levels 1, 3, and 5 mm from a coronal reference level for the control group. The test group showed dimensional changes of 4.8/2.3/1.3 mm at the three different levels, respectively. A significant difference was found at levels 3 and 5 mm. Referring to a visual analog pain scale, patients reported more severe pain in the control group (5.7/10) when compared with the test group (2.8/10). The difference was statistically highly significant (P ≤ 0.001). CONCLUSIONS A significant difference was found between control and test groups regarding the horizontal dimensional changes and the post-operative pain. CLINICAL RELEVANCE Regarding this primary result, the socket sealing technique with a hemostatic sponge provides an effective and inexpensive protocol with less post-operative pain.

Abstract
The aim of this systematic review was to explore the relationship between serum vitamin D levels and periodontal disease. The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The focused PICO question was: Are serum vitamin D levels (I) associated with gingivitis or periodontitis (C) in healthy humans (P)? PubMed (Medline), Embase, Science Direct, the Cochrane library, and grey literature were searched up to 31 July 2017. Two reviewers independently selected studies and extracted data. Quality, risk of bias, and heterogeneity of the studies were assessed using the Newcastle-Ottawa Scale. In total, 365 studies were identified and 24 were analyzed. Seven studies fulfilled the inclusion criteria. Four case-control studies showed an influence of vitamin D and its metabolites on periodontal health status/disease. One interventional study suggested the proposed anti-inflammatory role of vitamin D. Two cross-sectional studies failed to show a relationship between vitamin D and periodontal condition. The literature on the effect of serum vitamin D levels on periodontal status remains scarce and controversial. Some data, however, support a "perio-protective" role for vitamin D. There is a need for well-designed randomized clinical trials to explore the possible anti-inflammatory effect of vitamin D on periodontal health.

Abstract
Background Periopathogenic bacteria play an important role in the etiology of periodontal disease. At present, no study screening for periopathogens in the DR Congo was carried out. The aim of this pilot study was to investigate the prevalence of five periopathogens in Congolese patients with periodontitis and to determine the association between these bacteria. Material and Methods Twelve patients (eight women and four men) with a mean age of 45 ± 19 years from those consulted in dental services of two medical centers of Kinshasa from April 2017 to October 2017 were included. Full mouth examination was registered, the probing pocket depth and clinical attachment level were assessed at six sites per tooth. Dental subgingival plaque samples were taken in the deepest pocket per arch in the maxilla and mandible. DNA analysis was performed using DNA-strip technology. The Fisher Exact test and Pearson correlation were used for statistical analysis. Results Porphyromonas gingivalis and Tannerella forsythia were detected at high level of 92%, Prevotella intermedia at a rate of 75% whereas Treponema denticola was detected in all patients. Aggregatibacter actinomycetemcomitans was not detected. Strong associations were found between three bacteria of the red complex and between T. denticola and P. intermedia (r=1). Conclusions This first study investigating periopathogens in subgingival plaque of Congolese with periodontitis demonstrated a high prevalence of the red complex (P. gingivalis, T. forsythia and T. denticola). Associations between different bacteria of this complex were strong. Key words:Association, bacteria, periopathogen, periodontitis, prevalence.

Abstract
OBJECTIVE The beneficial effects of antiseptics in the treatment of periodontitis are still controversial. The goal of this randomized split-mouth study was to evaluate the clinical and microbiologic results of a unique subgingival irrigation of 10% povidone-iodine in addition to a full-mouth scaling and root planing for the treatment of chronic periodontitis. METHOD AND MATERIALS Twenty patients with chronic periodontitis took part in this investigation. In each patient, four initially untreated pockets ≥ 4 mm were randomly selected for one subgingival irrigation. After a one-session full-mouth treatment with scaling and root planing (SRP), two pockets of a split mouth received one unique irrigation with 10 mL 0.9% NaCl solution (control group, CG). Two pockets on the other side received 10 mL of povidone-iodine 10% (test group, PIG). Full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS), Plaque Index (PI), Gingival Index (GI), probing pocket depth (PPD), and clinical attachment level (CAL) parameters were assessed at baseline and after 1, 3, and 6 months (M). Bacterial samplings with sterile paper points were taken at M0 and after M1, M3, and M6. These samplings were separately cultured under aerobic and anaerobic conditions before CFU evaluation. RESULTS Pl, GI, PPD, and CAL were significantly improved in both groups after 6 months. The major difference was seen between M0 and M3 (P < .001). No significant differences were seen between the groups, except for deep pockets (> 6 mm) where a statistical difference was observed in favor of PIG after 6 months; in these subgroups the mean probing reduction was 2.68 ± 0.37 mm for CG versus 3.93 ± 0.23 mm in PIG (P < .001). No significant differences were seen between CG and PIG regarding the microbiologic results after 6 months. CONCLUSION One single irrigation of 10% povidone-iodine associated with full-mouth SRP would bring a small additional benefit in deep pockets. More studies are needed to yield additional results.

Abstract
Dental biofilms have been widely associated with biological complications of oral implants. Currently, no consensus exists regarding the most reliable anti-infective approach to treat peri-implantitis. This study aimed to investigate whether low direct electric currents (DC) could influence chlorhexidine (CHX) 0.2% antimicrobial efficacy against human dental biofilms. To support biofilm accumulation, discs made with machined titanium (Ti) or hydroxyapatite (HA) were used. Five volunteers wore during 24 h an intraoral thermoformed splint on which ten specimens were bonded. Biofilms were then collected and treated ex vivo. During each antimicrobial experiment (N = 20 replicates), two modalities of treatment (CHX/PBS = control groups and CHX/PBS+5mA = test groups) were tested (n = 5 discs each) and the number of viable bacteria evaluated in LogCFU/mL at baseline, 0.5, 1, 2 and 5 min. The proportion of killed bacteria was also estimated and compared statistically at each time point between control and test groups. CHX+/-5mA induced a mean viability reduction around 90-95% after 5 min of treatment whatever the surface considered (Ti/HA). A significant difference regarding the bactericidal effect was noted on Ti surfaces after 0.5, 1 and 2 min in favor of the CHX+5mA modality when compared to CHX alone (p < 0.05). PBS+5mA also had a certain antimicrobial effect (58%) after 5 min on Ti surfaces. This effect was significantly higher than that observed with PBS (25%) (p < 0.05). This study showed that low DC (5mA) can have an antibiofilm effect and are also able to enhance chlorhexidine 0.2% efficacy against human dental biofilms grown on titanium surfaces.

Abstract
Electric currents have been shown to promote the antimicrobial effectiveness of several biocides against microbial biofilms. Therefore, the objective of this work was to test the null hypothesis that low electric direct currents (DC) do not influence chlorhexidine (CHX) efficacy against the periodontal pathogen Porphyromonas gingivalis within a biofilm. A brain heart infusion medium inoculated with Streptococcus gordonii and P. gingivalis was perfused for 7 days in anaerobiosis through two modified Robbins devices (MRD) assembled in parallel. Biofilms grew on hydroxyapatite discs placed at the bottom of the MRD plugs, and were then treated for 10 min with either CHX or CHX/DC (1.5 mA or 10 mA). The bactericidal effect against biofilms was then evaluated by comparing the mean proportions of P. gingivalis killed. In the first series of experiments (CHX ± 1.5mA), the proportions of P. gingivalis killed were 81.1% for biofilms undergoing CHX and 79.1% when they were additionally treated with 1.5mA (p>0.05). In the second series (CHX ± 10mA), the viability of P.gingivalis was reduced by 87.3% with CHX and 98.9% when CHX was supplemented with 10mA (p<0.01). The null hypothesis was rejected, since a significant enhancement of the chlorhexidine 0.2% efficacy against P.gingivalis was observed when applying 10mA currents.
