- Background: Periodontitis and oral pathogenic bacteria can contribute to the development of rheumatoid arthritis (RA). A connection between serum antibodies to Porphyromonas gingivalis (P. gingivalis) and RA has been established, but data on saliva antibodies to P. gingivalis in RA are lacking. We evaluated antibodies to P. gingivalis in serum and saliva in two Swedish RA studies as well as their association with RA, periodontitis, antibodies to citrullinated proteins (ACPA), and RA disease activity.Methods: The SARA (secretory antibodies in RA) study includes 196 patients with RA and 101 healthy controls. The Karlskrona RA study includes 132 patients with RA >= 61 years of age, who underwent dental examination. Serum Immunoglobulin G (IgG) and Immunoglobulin A (IgA) antibodies and saliva IgA antibodies to the P. gingivalis-specific Arg-specific gingipain B (RgpB) were measured in patients with RA and controls.Results: The level of saliva IgA anti-RgpB antibodies was significantly higher among patients with RA than among healthy controls in multivariate analysis adjusted for age, gender, smoking, and IgG ACPA (p = 0.022). Saliva IgA anti-RgpB antibodies were associated with RA disease activity in multivariate analysis (p = 0.036). Anti-RgpB antibodies were not associated with periodontitis or serum IgG ACPA.Conclusion: Patients with RA had higher levels of saliva IgA anti-RgpB antibodies than healthy controls. Saliva IgA anti-RgpB antibodies may be associated with RA disease activity but were not associated with periodontitis or serum IgG ACPA. Our results indicate a local production of IgA anti-RgpB in the salivary glands that is not accompanied by systemic antibody production.

- Abstract Objectives. To assess the effects on intra-oral halitosis by a mouth rinse containing zinc acetate (0.3%) and chlorhexidine diacetate (0.025%) with and without adjunct tongue scraping. Materials and methods. Twenty-one subjects without a diagnosis of periodontitis were randomized in a cross-over clinical trial. Organoleptic scores (OLS) were assessed to define intra-oral halitosis by total volatile sulfur compound (T-VSC) measurements and by gas chromatography. Results. Twenty-one subjects with a mean age of 45.7 years (SD: ±13.3, range: 21-66). The OLS were significantly lower following active rinse combined with tongue scraping (p < 0.001) at all time points. Immediately after, at 30 min, and at day 14, the T-VSC values were lower in the active rinse sequence than in the negative rinse sequence (p < 0.001, p < 0.001 and p < 0.05, respectively). At 30 min and at day 14, the hydrogen sulfide (H(2)S) and methyl mercaptan (MM) values were lower in the active rinse sequence compared to the inactive rinse sequence (p < 0.001). The inactive rinse sequence with tongue scraping reduced T-VSC at 30 min (p < 0.001) but not at 14 days. Similar reductions in T-VSC, H(2)S and MM were found in the active rinse sequence with or without tongue scraping. Conclusion. The use of a tongue scraper did not provide additional benefits to the active mouth rinse, but reduced OLS and tongue coating index.

- OBJECTIVES: This study aims to assess the effects of rinsing with zinc- and chlorhexidine-containing mouth rinse with or without adjunct tongue scraping on volatile sulfur compounds (VSCs) in breath air, and the microbiota at the dorsum of the tongue. MATERIAL AND METHODS: A randomized single-masked controlled clinical trial with a cross-over study design over 14days including 21 subjects was performed. Bacterial samples from the dorsum of the tongue were assayed by checkerboard DNA-DNA hybridization. RESULTS: No halitosis (identified by VSC assessments) at day14 was identified in 12/21 subjects with active rinse alone, in 10/21with adjunct use of tongue scraper, in 1/21 for negative control rinse alone, and in 3/21 in the control and tongue scraping sequence. At day14, significantly lower counts were identified only in the active rinse sequence (p<0.001) for 15/78 species including, Fusobacterium sp., Porphyromonas gingivalis, Pseudomonas aeruginosa, Staphylococcus aureus, and Tannerella forsythia. A decrease in bacteria from baseline to day14 was found in successfully treated subjects for 9/74 species including: P. gingivalis, Prevotella melaninogenica, S. aureus, and Treponema denticola. Baseline VSC scores were correlated with several bacterial species. The use of a tongue scraper combined with active rinse did not change the levels of VSC compared to rinsing alone. CONCLUSIONS: VSC scores were not associated with bacterial counts in samples taken from the dorsum of the tongue. The active rinse alone containing zinc and chlorhexidine had effects on intra-oral halitosis and reduced bacterial counts of species associated with malodor. Tongue scraping provided no beneficial effects on the microbiota studied. CLINICAL RELEVANCE: Periodontally healthy subjects with intra-oral halitosis benefit from daily rinsing with zinc- and chlorhexidine-containing mouth rinse.

- AIM: The aim of this study was to evaluate the effects of non-surgical periodontal therapy on intra-oral halitosis 3 months after therapy.MATERIAL AND METHODS: Sixty-eight adults with intra-oral halitosis were included in a case series. Intra-oral halitosis was evaluated at baseline, and at 3 months after treatment using the organoleptic scores (OLS), Halimeter® , and a gas chromatograph.RESULTS: Significant reductions for OLS (p < 0.01), total sum of volatile sulphur compounds (T-VSC) (p < 0.01) and methyl mercaptan (MM) (p < 0.05) values were found after treatment. Hydrogen sulphide (H2 S) levels were not significantly reduced. The numbers of probing pockets 4 mm, 5 mm and 6 mm were significantly reduced as a result of therapy (p < 0.001). Bleeding on probing (BOP) and plaque indices were also significantly reduced (p < 0.001). For the 34 individuals with successful periodontal treatment (BOP<20% and a ≥50% reduction of total pocket depth) reductions in OLS (p < 0.01) and T-VSC scores (p < 0.01) were found. Eleven individuals were considered effectively treated for intra-oral halitosis presenting with a T-VSC value <160 ppb, a H2 S value <112 ppb and a MM value <26 ppb.CONCLUSION: Non-surgical periodontal therapy resulted in reduction of OLS, MM and T-VSC values 3 months after therapy. Few individuals were considered as effectively treated for intra-oral halitosis.

- Background Limited evidence exists on the efficacy of regenerative treatment of peri-implantitis. Material and Methods Subjects receiving antibiotics and surgical debridement were randomly assigned to placement of autogenous bone (AB) or bovine-derived xenograft (BDX) and with placement of a collagen membrane. The primary outcome was evidence of radiographic bone fill and the secondary outcomes included reductions of probing depth (PD) bleeding on probing (BOP) and suppuration. Results Twenty-two subjects were included in the AB and 23 subjects in the BDX group. Statistical analysis failed to demonstrate differences for 38/39 variables assessed at baseline. At 12 months, significant better results were obtained in the BDX group for bone levels (p < 0.001), BOP (p = 0.004), PI (p = 0.003) and suppuration (p < 0.01). When adjusting for number of implants treated per subject, a successful treatment outcome PD = 5.0 mm, no pus, no bone loss and BOP at 1/4 or less sites the likelihood of defect fill was higher in the BDX group (LR: 3.2, 95% CI: 1.010.6, p < 0.05). Conclusions Bovine xenograft provided more radiographic bone fill than AB. The success for both surgical regenerative procedures was limited. Decreases in PD, BOP, and suppuration were observed.

- OBJECTIVES: To assess if (I) the alveolar bone defect configuration at dental implants diagnosed with peri-implantitis is related to clinical parameters at the time of surgical intervention and if (II) the outcome of surgical intervention of peri-implantitis is dependent on defect configuration at the time of treatment.MATERIALS AND METHODS: In a prospective study, 45 individuals and 74 dental implants with ≥ 2 bone wall defects were treated with either an autogenous bone transplant or an exogenous bone augmentation material. Defect fill was assessed at 1 year.RESULTS: At baseline, no significant study group differences were identified. Most study implants (70.7%, n = 53) had been placed in the maxilla. Few implants were placed in molar regions. The mesial and distal crestal width at surgery was greater at 4-wall defects than at 2-wall defects (p = 0.001). Probing depths were also greater at 4-wall defects than at 2-wall defects (p = 0.01). Defect fill was correlated to initial defect depth (p < 0.001). Defect fill at 4-wall defects was significant (p < 0.05).CONCLUSIONS: (I) The buccal-lingual width of the alveolar bone crest was explanatory to defect configuration, (II) 4-wall defects demonstrated more defect fill, and (III) deeper defects resulted in more defect fill.

- Objectives The aim of this study was to assess the long-term efficacy of reconstructive treatment of peri-implantitis intraosseous defects. Material and Methods Peri-implant intraosseous defects were augmented using either an autogenous bone graft (AB) or a bovine-derived xenograft (BDX) in combination with a collagen membrane. Maintenance was provided every third month. Results In the AB group, 16 patients with 25 implants remained at year five. In the BDX group, 23 patients with 38 implants remained. Between baseline and year 5, bleeding on probing (BOP) and probing pocket depth (PPD) scores were reduced in both groups (p < .001). In the AB and BDX groups, mean PPD between baseline and year five was reduced by 1.7 and 2.8 mm, respectively. The difference between groups was significant (p < .001). In the AB group, the mean bone level change at implant level between baseline and years three and five was-0,2 and -0.7 mm, respectively. In the BDX group, the mean bone level change at implant level between baseline and years three and five was 1.6 and 1.6 mm, respectively. The difference between the groups was significant (p < .001). Successful treatment (no bone loss, no probing pocket depth (PPD) > 5 mm, no suppuration, maximum one implant surface with bleeding on probing (BOP) at year five) was obtained in 9/25 implants (36%) in the AB group and in 29/37 implants (78.3%) in the BDX group. Conclusions Reconstructive surgical treatment of peri-implant defects using BDX resulted in more predictable outcomes than using autogenous bone over 5 years.

- Aims: To investigate clinical, radiographic and microbiological outcome over 12months following open flap debridement of peri-implantitis with or without antibiotics. Materials and methods: Peri-implantitis was surgically treated with or without Zithromax((R)) in 19 control and 20 test individuals. Probing pocket depth (PPD), gingival inflammation (BOP), intra-oral radiographs and microbial samples were studied. Per protocol and intent-to-treat analyses were performed. Results: The mean difference (reduction) in PPD values between baseline and month 12 in the test and control groups was 1.7mm (SD1.1, 95% CI: 1.1, 2.3, p<.001) and 1.6mm (SD +/- 1.5, 95% CI: 0.8, 2,4, p<.001), respectively. Data analysis failed to show study group differences for BOP, PPD, radiographic bone level and microbial load. Successful treatment (per protocol: PPD5mm, no BOP, no suppuration and no bone loss 0.5mm) at 12months in test and control groups was 7/15 (46.7%) and 4/16 (25.0%). Bacterial load reduction was similar in study groups with a temporary reduction following treatment. Conclusions: Surgical treatment of peri-implantitis with adjunctive systemic azithromycin did not provide 1-year clinical benefits in comparison with those only receiving open flap debridement.

- Objective The aim of the present study was to investigate the reproducibility of bacterial enumeration from subsequent subgingival samples collected from patients with peri-implant mucositis. Material and methods Duplicate microbial samples from 222 unique implant sites in 45 adult subjects were collected with paper points and analyzed using the checkerboard DNA-DNA hybridization technique. Whole genomic probes of 74 preselected bacterial species were used. Based on the bacterial scores, Cohen's kappa coefficient was used to calculate the inter-annotator agreement for categorical data. The percentage agreement was considered as "good" when the two samples showed the same score or differed by 1 to the power of 10. Results Moderate to fair kappa values were displayed for all bacterial species in the test panel (range 0.21-0.58). There were no significant differences between Gram-positive and Gram-negative species. The percentage of good agreement between the first and second samples averaged 74.7 % (n=74; range 56-83 %), while the proportion of poor agreement ranged from 1 to 19 % for the various strains. Conclusion While an acceptable clinical agreement was obtained in most cases, diverging bacterial scores may appear in subgingival samples collected at the same time point from patients with peri-implant mucositis. Clinical relevance The broad bulky base of implant crowns may present an obstacle for the collection of reproducible subgingival samples with paper points.

- OBJECTIVE: To evaluate if the presence of periodontitis is associated with carotid arterial calcifications diagnosed on panoramic radiographs in an elderly population.MATERIALS AND METHODS: Study individuals were randomly selected from the Swedish civil registration database representing the aging population (60-96 years) in Karlskrona, Sweden. Bleeding on probing (BOP) and the deepest probing measurement at each tooth were registered. The proportions of teeth with a probing depth ≥ 5 mm and the proportion of teeth with bleeding on probing were calculated. Analog panoramic radiographs were taken and the proportion of sites with a distance ≥ 5 mm between the alveolar bone level and the cement-enamel junction (CEJ) were assessed. A diagnosis of periodontitis was declared if a distance between the alveolar bone level and the CEJ ≥ 5 mm could be identified from the panoramic radiographs at > 10% of sites, probing depth of ≥ 5 mm at one tooth or more and with BOP at > 20% of teeth.RESULTS: Readable radiographs were obtained from 499 individuals. Carotid calcification was identified in 39.1%. Individuals were diagnosed with periodontitis in 18.4%. Data analysis demonstrated that individuals with periodontitis had a higher prevalence of carotid calcifications (Pearson χ(2) = 4.05 p < 0.05) and with a likelihood of 1.5 (95% CI = 1.0, 2.3, p < 0.05).CONCLUSIONS: Data analysis demonstrated a significant association between periodontitis and carotid calcification.
