RESUMO
OBJECTIVES: To assess if the results following intake of a diet using an Okinawan-based Nordic diet (OBND) over one month differs in endocrinological, periodontal clinical outcome, and serum cytokine levels compared to a standard hospital care diet in individuals with diabetes type 2 (T2D) (control group). BACKGROUND: Scientific evidence suggests that the use of diet for individuals with T2D may be beneficial. METHODS: Participating individuals with T2D were randomly assigned to a test (OBND) (n = 14), or control group (n = 16). Anthropometric data, blood glucose levels, HbA1c levels, lipids, serum inflammation markers (CRP, and a routine panel of 24 cytokines), blood pressure, gingival bleeding on probing (BOP), probing pocket depths (PPD), and clinical attachment levels (CAL) were studied. RESULTS: Statistical analyses of baseline study data failed to demonstrate study group differences. The mean weight reduction was greater in the OBND group (4.1 kg) versus the control group (1.3 kg) (p < 0.01). The reduction in BMI was 1.4 kg/m2 in OBND (p < 0.001) and 0.5 kg/m2 in the control group, respectively (p < 0.01). Diastolic and systolic blood pressure reductions were greater in the OBND group than in the control group (p < 0.01). Periodontal study parameters (BOP % scores) and (PPD values) decreased (p < 0.001) overall with no between group differences. The OBND resulted in reduction of serum levels of IFNγ, Eotaxin IL-9, IP10,IL17a, MCP-1,m and PDFBB compared to the control diet. CONCLUSIONS: A strict T2D- diet provides an association between reduction in serum HbA1c and BOP scores. Serum levels decreases in IFNγ, Eotaxin IL-9, IP-10, IL17a. MCP-1, and PDFBB were only found in the test group.

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.

BACKGROUND: The Clinical Oral Disorder in Elders (CODE) index was proposed in 1999 to assess the oral health status and treatment needs of older people who typically were edentate or had few natural teeth. Since then, more people are retaining natural teeth into old age and have oral disorders similar to younger adults. In addition, there has been further guidance on screening for disease that includes changes to the clinical indicators of several oral disorders and greater sensitivity to people's concerns about their oral health and care needs. METHODS: Experts in dental geriatrics assembled at a satellite symposium of the International Association of Dental Research in June 2019 to revise the objectives and content of the CODE index. Before the symposium, 139 registrants were asked for comments on the CODE index, and 11 content experts summarised current evidence and assembled reference lists of relevant information on each indicator. The reference lists provided the base for a narrative review of relevant evidence supplemented by reference tracking and direct searches of selected literature for additional evidence. RESULTS: Analysis of the evidence by consensus of the experts produced the Clinical Oral Disorders in Adults Screening Protocol (CODA-SP). CONCLUSIONS: The CODA-SP encompasses multiple domains of physical and subjective indicators with weighted severity scores. Field tests are required now to validate its effectiveness and utility in oral healthcare services, outcomes and infrastructure.

OBJECTIVE: To assess if carotid calcifications detected in panoramic radiographs are associated with future events of stroke, and/or ischemic heart diseases over 10-13 years in individuals between 60 and 96 years. MATERIALS AND METHODS: Baseline (2001-2004) panoramic radiographs were assessed for evidence of carotid calcifications from individuals with no previous history of stroke and/or ischemic heart diseases. A radiopaque nodular mass adjacent to the cervical vertebrae, at or below the intervertebral space C3-C4, was interpreted as carotid calcification. Annual medical records were searched for ICD 10 codes through 2014. RESULTS: Signs of carotid calcification was demonstrated in 238/635 (37.5%) of the study individuals. Signs of carotid calcification was associated with future stroke and/or ischemic heart diseases (χ2 = 9.1, OR 1.6, 95% CI 1.2, 2.2, p < 0.002). In individuals 60-72 years, a significant association between radiographic signs of carotid calcification and stroke and/or ischemic heart diseases (χ2 = 12.4, OR 2.4, 95% CI 1.5, 4.0, p < 0.000) (adjusted for high blood pressure, diabetes type 2, BMI; OR 1.9, 95% CI 1.1, 3.5, p = 0.03). Individuals (60-72 years) with radiographic evidence of carotid calcifications had a mean cumulative stroke and/or ischemic heart diseases survival time of 12.1 years compared to those without such evidence (13.0 years) (log rank Mantel-Cox χ2 = 10.7, p = 0.001). CONCLUSIONS: Evidence of carotid calcifications in panoramic radiographs is associated with an event of stroke and/or ischemic heart diseases in 60-96-year-old individuals. CLINICAL RELEVANCE: Radiographic evidence of carotid calcifications is associated with stroke and/or ischemic heart diseases. Patients with signs of carotid calcifications should therefore be referred for medical examination.

The objective of this review is to identify case definitions and clinical criteria of peri-implant healthy tissues, peri-implant mucositis, and peri-implantitis. The case definitions were constructed based on a review of the evidence applicable for diagnostic considerations. In summary, the diagnostic definition of peri-implant health is based on the following criteria: 1) absence of peri-implant signs of soft tissue inflammation (redness, swelling, profuse bleeding on probing), and 2) the absence of further additional bone loss following initial healing. The diagnostic definition of peri-implant mucositis is based on following criteria: 1) presence of peri-implant signs of inflammation (redness, swelling, line or drop of bleeding within 30 seconds following probing), combined with 2) no additional bone loss following initial healing. The clinical definition of peri-implantitis is based on following criteria: 1) presence of peri-implant signs of inflammation, 2) radiographic evidence of bone loss following initial healing, and 3) increasing probing depth as compared to probing depth values collected after placement of the prosthetic reconstruction. In the absence of previous radiographs, radiographic bone level ≥3 mm in combination with BOP and probing depths ≥6 mm is indicative of peri-implantitis.

AIMS: To investigate clinical, radiographic and microbiological outcome over 12 months following open flap debridement of peri-implantitis with or without antibiotics. MATERIALS AND METHODS: Peri-implantitis was surgically treated with or without Zithromax® 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 1.7 mm (SD ± 1.1, 95% CI: 1.1, 2.3, p < .001) and 1.6 mm (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: PPD ≤ 5 mm, no BOP, no suppuration and no bone loss ≥0.5 mm) at 12 months 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.

AIM: We aimed to study how lipopolysaccharide (LPS) in saliva and serum associates with each other, periodontal microbial burden, periodontitis and coronary artery disease (CAD). MATERIALS AND METHODS: The used Parogene cohort comprised N = 505 Finnish adults. Coronary diagnosis was acquired by coronary angiography, and the main outcomes were as follows: no significant CAD (n = 123), stable CAD (n = 184) and acute coronary syndrome (n = 169). Periodontitis was defined according to clinical and radiographic examinations. Levels for 75 strains of subgingival bacteria were determined by checkerboard DNA-DNA hybridization. Saliva and serum LPS activity was analysed by Limulus amebocyte lysate assay. RESULTS: The level of 11 bacterial strains, which were mainly oral and respiratory Gram-negative species, associated with salivary LPS levels in an age- and gender-adjusted linear regression. A total of 4.9% of the serum LPS, that is endotoxemia, variation was explainable by saliva LPS among patients with periodontitis (n = 247, R2 = .049, Pearson's r = .222, p < .001). Endotoxemia associated with stable CAD in a confounder adjusted multinomial logistic regression model (OR 1.99, 95% CI 1.04-3.81, p = .039, 3rd tertile). CONCLUSIONS: In particular in periodontitis patients, subgingival microbial burden contributes to endotoxemia. LPS is a possible molecular mediator between periodontitis and CAD.

Within the next 40 years the number of older adults worldwide will more than double. This will impact periodontal treatment needs and presents a challenge to health-care providers and governments worldwide, as severe periodontitis has been reported to be the sixth most prevalent medical condition in the world. Older adults (≥ 80 years of age) who receive regular dental care retain more teeth than those who do not receive such care, but routine general dental care for these individuals is not sufficient to prevent the progression of periodontitis with the same degree of success as in younger individuals. There is a paucity of data on the efficacy of different periodontal therapies for older individuals. However, considering the higher prevalence of chronic medical conditions seen in older adults, it cannot be assumed that periodontal therapy will yield the same degree of success seen in younger individuals. Furthermore, medications can influence the status of the periodontium and the delivery of periodontal care. As an example, anticoagulant drugs are common among older patients and may be a contraindication to certain treatments. Newer anticoagulants will, however, facilitate surgical intervention in older patients. Furthermore, prescription medications taken for chronic conditions, such as osteoporosis and cardiovascular diseases, can affect the periodontium in a variety of ways. In summary, consideration of socio-economic factors, general health status and multiple-drug therapies will, in the future, be an important part of the management of periodontitis in older adults.

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.
RESUMO
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.

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.

Bioactive molecules in berries may be helpful in reducing the risk of oral diseases. The aim of this study was to determine the effect of bilberry consumption on the outcome of a routine dental clinical parameter of inflammation, bleeding on probing (BOP), as well as the impact on selected biomarkers of inflammation, such as cytokines, in gingival crevicular fluid (GCF) in individuals with gingivitis. Study individuals who did not receive standard of care treatment were allocated to either a placebo group or to groups that consumed either 250 or 500 g bilberries daily over seven days. The placebo group consumed an inactive product (starch). A study group, receiving standard of care (debridement only) was also included to provide a reference to standard of care treatment outcome. Cytokine levels were assayed using the Luminex MagPix system. The mean reduction in BOP before and after consumption of test product over 1 week was 41% and 59% in the groups that consumed either 250 or 500 g of bilberries/day respectively, and was 31% in the placebo group, and 58% in the standard of care reference group. The analysis only showed a significant reduction in cytokine levels in the group that consumed 500 g of bilberries/day. A statistically significant reduction was observed for IL-1b (p=0.025), IL-6 (p=0.012) and VEGF (p=0.017) in GCF samples in the group that consumed 500 g of bilberries daily. It appears that berry intake has an ameliorating effect on some markers of gingival inflammation reducing gingivitis to a similar extent compared to standard of care.

OBJECTIVES: To assess the literature on carotid calcifications defined from panoramic radiographs (PMX) and concurrent diagnosis of stroke and periodontitis. MATERIALS AND METHODS: A literature search screening for publications using search terms such as PMX and carotid calcification, stroke and periodontitis was performed in November 2012. RESULTS: A total of 189 articles were retrieved, among which 30 were included in the review. The sensitivity for PMX findings of carotid calcifications (CC) compared to a diagnosis by Doppler sonography varied between 31.1-100%. The specificity for PMX findings of carotid calcifications compared to a diagnosis by Doppler sonography varied between 21.4-87.5%. Individuals with CC findings from PMX have more periodontitis and risk for stroke. CONCLUSIONS: There is a shortage of well-designed studies in older dentate individuals assessing the associations between periodontitis and radiographic evidence of CC and in relation to stroke or other cardiovascular diseases. STATEMENT OF CLINICAL RELEVANCE: Carotid calcifications are prevalent in patients with periodontitis and such individuals may have an increased risk for stroke. The absence of signs of carotid calcification on panoramic radiographs is indicative of no calcification of carotid arteries.

AIM: We investigated the association between angiographically verified coronary artery disease (CAD) and subgingival Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola. MATERIALS AND METHODS: The cross-sectional study population (n = 445) comprised 171 (38.4%) patients with Stable CAD, 158 (35.5%) with acute coronary syndrome (ACS) and 116 (26.1%) with no significant CAD (No CAD). All patients participated in clinical and radiological oral health examinations. Pooled subgingival bacterial samples were analysed by checkerboard DNA-DNA hybridization assays. RESULTS: In all study groups, the presence of P. gingivalis, T. forsythia and T. denticola indicated a significant (p ≤ 0.001) linear association with the extent of alveolar bone loss (ABL), but A. actinomycetemcomitans did not (p = 0.074). With a threshold level of bacterial cells 1 × 10(5) A. actinomycetemcomitans was significantly more prevalent in the Stable CAD group (42.1%) compared to the No CAD group (30.2%) (p = 0.040). In a multi-adjusted logistic regression analysis using this threshold, A. actinomycetemcomitans positivity associated with Stable CAD (OR 1.83, 95% CI 1.00-3.35, p = 0.049), but its level or levels of other bacteria did not. CONCLUSIONS: The presence of subgingival A. actinomycetemcomitans associates with an almost twofold risk of Stable CAD independently of alveolar bone loss.

OBJECTIVES: We assessed if adjunct administration of piperacillin/tazobactam added clinical and microbiological treatment benefits. MATERIALS AND METHODS: Thirty-six subjects (mean age 52.1 years (SD ± 10.3)) (NS by group) with chronic periodontitis were randomly enrolled receiving subgingival debridement and the local administration of piperacillin/tazobactam (test group) or debridement alone (control group). Bleeding on probing (BOP), probing pocket depth (PPD), and microbiological counts of 74 species were studied by checkerboard DNA-DNA hybridization up to month 6 after treatment. RESULTS: Mean PPD changes between baseline and month 6 in the test and control groups were 1.5 and 1.8 mm, respectively (NS between groups). BOP in both groups decreased from about 80 to 40 %. At 4 and 12 weeks, lower counts of the following bacteria were found in the test group (site level): Fusobacterium species, Parvimonas micra, Pseudomonas aeruginosa, Staphylococcus aureus, Tannerella forsythia, Treponema denticola, and a composite load of nine pathogens (p < 0.001). At week 26, subjects receiving local antibiotics had a lower prevalence at tested sites for Fusobacterium nucleatum sp. polymorphum, Fusobacterium periodonticum, P. micra, and T. denticola. CONCLUSIONS: At 26 weeks, treatment with or without piperacillin/tazobactam resulted in similar BOP and PPD improvements. At week 26 and at the subject level, the prevalence of 4/74 pathogens was found at lower counts in the group receiving local antibiotics. CLINICAL RELEVANCE: Administration of piperacillin/tazobactam reduces the prevalence of Fusobacterium, P. micra, and T. denticola to a greater extent than debridement alone but with no short-term differences in PPD or BOP.

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 14 days 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 day 14 was identified in 12/21 subjects with active rinse alone, in 10/21 with 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 day 14, 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 day 14 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.

OBJECTIVES: The aim of this study was to assess gingival fluid (GCF) cytokine messenger RNA (mRNA) levels, subgingival bacteria, and clinical periodontal conditions during a normal pregnancy to postpartum. MATERIALS AND METHODS: Subgingival bacterial samples were analyzed with the checkerboard DNA-DNA hybridization method. GCF samples were assessed with real-time PCR including five proinflammatory cytokines and secretory leukocyte protease inhibitor. RESULTS: Nineteen pregnant women with a mean age of 32 years (S.D. ± 4 years, range 26-42) participated in the study. Full-mouth bleeding scores (BOP) decreased from an average of 41.2% (S.D. ± 18.6%) at the 12th week of pregnancy to 26.6% (S.D. ± 14.4%) at the 4-6 weeks postpartum (p < 0.001). Between week 12 and 4-6 weeks postpartum, the mean probing pocket depth changed from 2.4 mm (S.D. ± 0.4) to 2.3 mm (S.D. ± 0.3) (p = 0.34). Higher counts of Eubacterium saburreum, Parvimonas micra, Selenomonas noxia, and Staphylococcus aureus were found at week 12 of pregnancy than at the 4-6 weeks postpartum examinations (p < 0.001). During and after pregnancy, statistically significant correlations between BOP scores and bacterial counts were observed. BOP scores and GCF levels of selected cytokines were not related to each other and no differences in GCF levels of the cytokines were observed between samples from the 12th week of pregnancy to 4-6 weeks postpartum. Decreasing postpartum counts of Porphyromonas endodontalis and Pseudomonas aeruginosa were associated with decreasing levels of Il-8 and Il-1ß. CONCLUSIONS: BOP decreased after pregnancy without any active periodontal therapy. Associations between bacterial counts and cytokine levels varied greatly in pregnant women with gingivitis and a normal pregnancy outcome. Postpartum associations between GCF cytokines and bacterial counts were more consistent. CLINICAL RELEVANCE: Combined assessments of gingival fluid cytokines and subgingival bacteria may provide important information on host response.

PURPOSE: To review treatment modalities used for peri-implant mucositis and peri-implantitis. METHODS: A literature search was performed in PubMed for articles published until May 2013 using peri-implantitis and peri-implant mucositis and different modalities of treatment as search terms. The search was limited to the English literature. Titles and abstracts were searched in order to find studies eligible for the review. RESULTS: The present review reported that treatment of peri-implant mucositis lesions using mechanical therapy is possible. The additional use of professionally delivered antimicrobials has commonly failed to show additional benefits as compared to mechanical debridement alone. The scientific evidence on the efficacy of non-surgical and surgical therapies in the treatment of peri-implantitis is limited. Complete resolution of peri-implantitis using mechanical, laser, or photodynamic therapy does not seem to result in a predictable outcome. Following surgical interventions around implants diagnosed with peri-implantitis, clinical improvements as judged by reductions of probing depths and bleeding on probing have been reported. Bone or bone substitutes have been used in attempts to regenerate bone loss around implants. When regenerative modalities have been employed, radiographic evidence of defect fill has been reported. Few long term follow up studies on the treatment of peri-implantitis are available. Positive treatment results can be maintained over a period of 3-5 years. Regardless of the treatment performed, adequate plaque control by the patient is fundamental to treatment success. If the patient cannot obtain an adequate level of oral hygiene, the infection around the implants will reoccur.

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.

BACKGROUND: This RCT compared non-surgical treatment of peri-implant mucositis with or without systemic antibiotics. MATERIALS AND METHODS: Forty-eight subjects received non-surgical debridement with or without systemic Azithromax (®) (4 days), and were followed during 6 months. The checkerboard DNA-DNA hybridization method was used to analyse the microbiological material. RESULTS: Five subjects were excluded due to antibiotic medication during follow-up. At baseline,1 and 3 months no group differences were found. Statistical analysis failed to demonstrate differences in probing pocket depths (PPD) values at 6 months (Mean diff PPD: 0.5 mm, SE: ±0.4 mm, 95% CI: -0.2, 1.3, p = 0.16). Mean% implant bleeding decreased between baseline and month 6 from 82.6% to 27.3% in the test, and from 80.0% to 47.5% in the control group (p < 0.02). Throughout the study, no study group differences in bacterial counts were found. CONCLUSION: No short-term differences were found between study groups. The clinical improvements observed at 6 months may be attributed to improvements in oral hygiene. The present study does not provide evidence for the use of systemic antibiotics in treatment of peri-implant mucositis.
