- BACKGROUND/AIM: Conventional mechanical periodontal treatment of Papillon-Lefevre syndrome (PLS) has often been reported to fail. This study describes the outcome of a non-surgical periodontal therapy including antimicrobial treatment of nine patients diagnosed with PLS. The patients originate from a total of 15 children and adolescents with PLS for which clinical characteristics are presented.METHODS: Clinical examination including conventional periodontal measurements. Initial treatment including oral hygiene instruction, scaling and root planing and systemic amoxicillin-metronidazole therapy for 6 weeks. After that the patients were enrolled in a 3-month recall maintenance program. In addition to this mechanical supportive maintenance treatment, tetracycline was prescribed and used continuously for 1.5 years.RESULTS/CONCLUSION: On five patients who were showing acceptable standard of oral hygiene and also compliance with the antibiotic medication, development of periodontitis on erupting teeth was prevented and disease activity on the previously periodontally involved teeth controlled during a 3-year period. Poor results of treatment were observed for three patients, all siblings. These patients failed to comply with the medication and also failed to improve their oral hygiene.

- This study investigated whether osseointegration can occur on a surface which had previously been coated with dental plaque. The mandibular premolar regions of four young adult Labrador dogs were used for the study. The lower premolars (P1, P2, P3, and P4) were extracted on either side of the mandibles. Following a 12-week healing period, three 3.75 mm x 13 mm commercially pure titanium implants (Nobel BiocareAB, Gothenburg, Sweden) were partially inserted in one side of each mandible. This resulted in some threads protruding from the tissues into the oral cavity. Plaque was allowed to accumulate on the exposed implant surfaces. Following a 5-week healing period, the contaminated parts of each implant were treated using three different cleaning techniques: (1) swabbing with supersaturated citric acid for 30 s on a cotton pellet followed by rinsing with physiological saline, (2) cleansing with a toothbrush and physiological saline only for 1 min, and (3) swabbing with 10% hydrogen peroxide (H2O2) on a cotton pellet for 1 min followed by rinsing with physiological saline. The treated implants and one previously unused implant (control) were then placed into freshly prepared tapped sites to the full implant length on the contralateral sides of the mandibles. Following 11 weeks of healing, biopsies were obtained and ground sections prepared for histomorphometric analysis. All treatment modalities were associated with direct bone to implant contact on the portion of implant surface previously exposed to the oral environment. In conclusion, The results demonstrate that osseointegration can occur to surfaces that were plaque contaminated and cleaned by different methods.

- BACKGROUND: The aim of this study was to evaluate the long-term outcome of a combined surgical and antimicrobial treatment of peri-implantitis lesions in humans.METHODS: Nine partially dentate individuals with titanium implants demonstrating a marginal bone loss of > or = three threads as compared to baseline measurements made from 1-year intra-oral radiographs, bleeding on probing, and/or suppuration from the peri-implant sulci were included in the study. In each individual, subgingival bacterial samples were obtained and subjected to microbiological analysis by culture. Surgical exposure of the lesions and cleaning of the implants using hydrogen peroxide were performed. The patients were given systemic antibiotics according to a susceptibility test of target bacteria. The treatment was evaluated clinically, microbiologically, and radiograpically at 6 months, 1 year, and 5 years.RESULTS: Seven out of 26 implants with peri-implantitis at baseline were lost during the 5-year follow-up period despite a significant reduction in the presence of plaque and gingival bleeding. Four implants continued to lose bone, 9 had an unchanged bone level, and 6 gained bone. Five of the patients were treated with antibiotics directed against putative periodontopathogens, i.e., A. actinomycetemcomitans, P. intermedia, or P. gingivalis; three patients were treated for presence of enterics (E. coli and E. cloace); and, in one patient, treatment was directed against S. aureus.CONCLUSIONS: Despite treatment and retreatment, seven implants were lost. However, the applied surgical and antimicrobial treatment strategy for advanced peri-implantitis lesions was successful in 58% of the implants treated during the 5-year follow-up period. Smoking seemed to be a negative risk factor for treatment success.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to evaluate if a mass media campaign regarding periodontal disease could increase the knowledge in the general population of diagnoses, symptoms and treatment options of periodontal disease. More specifically, the aim was to investigate the number of correct answers to knowledge questions before and after the campaign. The Swedish Association of Periodontology conducted the campaign through brochures, newspapers, radio and TV. The effect of the campaign was evaluated by a pre- and post campaign questionnaire with a cohort design. From a national population register of 50-75 year olds in Sweden, 900 persons were randomly sampled for the study. A total of 64% of the sample answered both questionnaires. The result of the study showed an improvement among the respondents. There was a significant increase in the number of correct answers regarding diagnoses, symptoms and treatments of periodontitis. In the questionnaire, correct answers regarding "Mobile teeth" increased from 57% to 65% (p=0.003) and "careful dental hygiene" from 65% to 73% (p=0.001). Kappa value's were calculated for consistency in the reply and all kappa values were low especially for the questions "X-ray" (0.36) and "Cleaning between the teeth" (0.38). It was concluded that the campaign probably was successful from a public health knowledge standpoint.

- BACKGROUND: An association between periodontitis and cardiovascular diseases has been suggested.AIMS: To study whether a combination of clinical variables in a functional risk diagram enhanced the ability to differentiate between subjects with or without an immediate history of acute myocardial infarction (AMI).MATERIAL AND METHODS: A functional periodontal pentagon risk diagram (PPRD) with five periodontal risk vectors was created. The surface of individual PPRDs was calculated using data from 88 subjects with recent AMI and 80 matched control subjects with no history of AMI.RESULTS: Age, gender, number of remaining teeth (mean value: 21.1 versus 21.6 teeth), smoking status, and pocket probing depth (PPD) distribution did not differ by group. Gingival recession was greater in control subjects (mean difference: 5.7, SD: +/- 1.9, p<0.01, 95% CI: 1.8-9.6). Bone loss > or = 4.0 mm was at all levels studied was significantly greater in subjects with AMI and bone loss > or = 50% (> or = 4 mm) was the best individual predictor of AMI (beta = 2.99, p < 0.000, 95% CI: 7.5-53.4). Only PPRD scores were associated with AMI status when factors not included in the PPRD were studied (beta = 22.1, SE: 5.9, p < 0.0001, 95% CI: 10.3-33.7). The best association between AMI status and study variables was the combination of > or = 4 mm of bone loss > or = 50%, proportion of bleeding on probing (%BOP), %PPDs > or = 6 mm, and tooth loss (Nagelkirke r2 = 0.46).CONCLUSIONS: The combination of five periodontal parameters in a PPRD added predictive value, suggesting that comprehensive data should be used in studies of associations between periodontitis and heart diseases. Radiographic evidence of bone loss was the best individual parameter.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- I framtiden kommer den äldre befolkningen att ha fler egna tänder. Ökad ålder är ofta förknippad med försämrad medvetenhet, reducerad motorik och ökad användning av läkemedel. Dessa faktorer kan påverka möjligheterna att upprätthålla en adekvat munhygien, vilket ökar risken för parodontit och karies. Förekomsten av P gingivalis och B forsythus, rökning och ett försämrat immunförsvar ökar också risken för parodontit. Flera allmänsjukdomar, t ex diabetes och kardiovaskulära sjukdomar, är vanligare bland äldre. Ett samband mellan parodontit och kardiovaskulära sjukdomar har redovisats. Även om det är för tidigt att dra långtgående slutsatser om sambandet mellan parodontit och allmänsjukdomar kan det från allmän preventiv synpunkt vara indicerat att behandla parodontit ur allmänmedicinsk aspekt. Det finns ingen anledning tro att parodontal behandling av äldre inte är framgångsrik. Enbart ålder kan därför inte utgöra ett hinder för behandling. Klorhexidin kan vid behov användas som ett supplement till mekanisk tandrengöring under såväl kortare som längre tidsperioder.

- BACKGROUND: Limited subject-based information exists on the relationship between clinical and radiographic periodontal data.AIMS: To use subject-based data to assess the extent of concurrence between clinical and radiographic information, and to study what clinical information best predicts alveolar bone loss (ABL). Material and Methods: Subject-based data on smoking habits, bleeding on probing, plaque scores, pocket probing depth (PD), and evidence of alveolar BL were obtained, and functional periodontal pentagon risk diagrams (PPRDs) were studied from 168 consecutive subjects attending a medical clinic.RESULTS: The mean age of the subjects was 62.7 years (SD+/-9.0). The average number of teeth was 21.3 (SD+/-8.0) with on average 5.6 molars remaining (SD+/- 3.9). In this subject cohort, 33.1% had never smoked, 44.2% had quit smoking, and 22.7% were currently smokers. Mean plaque and bleeding scores were high or 60.2% (SD+/-24.0) and 53.1% (SD+/-23.6), respectively. PDs >or=6.0 mm were found in 55.9% of the subjects. Binary logistic regression analysis demonstrated that tooth loss and proportional plaque scores were the predominant factors included in the equations associated with ABL. Wald coefficients varied between 3.99 and 9.15, and with p-values between 0.05 and 0.01. When included, the PPRD score became the exclusive factor at several cut-off levels (Wald's coefficients between 19.8 and 15.6, p<0.001). Consequently, the best receiver operator curve was identified for the PPRD at the >40% cut-off ABL level (area under the curve: 0.81; 95% CI: 0.74-0.89; p<0.001).CONCLUSIONS: The number of teeth lost and the proportion of plaque scores provided significant predictive factors for ABL. The functional PPRD demonstrated an exclusive and highly predictable association with ABL. Subject-based proportional data for PDs >4.0 mm provided poor substitute measures for the extent of ABL.
