  • Change in Oral Impacts on Daily Performances (OIDP) with increasing age : testing the evaluative properties of the OIDP frequency inventory using prospective data from Norway and Sweden
  • 2014
  • Ingår i: BMC Oral Health. - : BioMed Central. - 1472-6831 .- 1472-6831. ; 14
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Oral health-related quality of life, OHRQoL, among elderly is an important concern for the health and welfare policy in Norway and Sweden. The aim of the study was to assess reproducibility, longitudinal validity and responsiveness of the OIDP frequency score. Whether the temporal relationship between tooth loss and OIDP varied by country of residence was also investigated.METHODS: In 2007 and 2012, all inhabitants born in 1942 in three and two counties of Norway and Sweden were invited to participate in a self-administered questionnaire survey. In Norway the response rates were 58.0% (4211/7248) and 54.5% (3733/6841) in 2007 and 2012. Corresponding figures in Sweden were 73.1% (6078/8313) and 72.2% (5697/7889), respectively.RESULTS: Reproducibility of the OIDP in terms of intra-class correlation coefficient (ICC) was 0.73 in Norway and 0.77 in Sweden. The mean change scores for OIDP were predominantly negative among those who worsened, zero in those who did not change and positive in participants who improved change scores of the reference variables; self-reported oral health and tooth loss. General Linear Models (GLM) repeated measures revealed significant interactions between OIDP and change scores of the reference variables (p < 0.05). Stratified analysis revealed that the mean OIDP frequency score worsened in participants who became dissatisfied- and improved in participants who became satisfied with oral health. Compared to participants who maintained all teeth, those who lost teeth were more likely to experience improvement and worsening of OIDP across both countries. The two-way interaction between country and tooth loss was not statistically significant.CONCLUSIONS: Changes in OIDP at the individual level were more pronounced than the percentage distribution of OIDP at each point in time would suggest. The OIDP frequency score showed promising evaluative properties in terms of acceptable longitudinal validity, responsiveness and reproducibility among older people in Norway and Sweden. This suggests that the OIDP instrument is able to detect change in the oral health status that occurred over the 5 year period investigated. Norwegian elderly were more likely to report worsening in OIDP than their Swedish counterparts. Disease prevention should be at focus when formulating the health policy for older people.

  • Antibiotic prescription in bone augmentation and dental implant procedures : a multi-center study
  • 2023
  • Ingår i: BMC Oral Health. - : BioMed Central (BMC). - 1472-6831. ; 23:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Adherence to antibiotic recommendations and safety aspects of restrictive use are important components when combating antibiotic resistance. The primary aim of this study was to assess the impact of national guidelines on antibiotic prescriptions for bone augmentation procedures among dentists working at three specialized clinics. The secondary aim was to assess the occurrence of postoperative infections.METHODS: Medical charts of 400 patients treated with bone augmentation were reviewed: 200 in the years 2010-2011 and 200 in 2014-2015. The Swedish national recommendations for antibiotic prophylaxis were published in 2012.RESULTS: There was a wide variation in antibiotic regiments prescribed throughout the study. The number of patients treated with antibiotic prophylaxis in a single dose of 2 g amoxicillin, and treated as advocated in the national recommendations, was low and decreasing between the two time periods from 25% (n = 50/200) in 2010-2011 to 18.5% (n = 37/200) in 2014-2015. The number of patients not given any antibiotics either as a prophylactic single dose or during the postoperative phase increased (P < 0.001). The administration of a 3-7-days antibiotic prescription increased significantly from 25.5% in 2010-2011 to 35% in 2014-2015. The postoperative infection rates (4.5% and 6.5%) were without difference between the studied periods. Smoking and omitted antibiotic prophylaxis significantly increased the risk of postoperative infection. Logistic regression analyses showed that patient male gender and suffering from a disease were predictive factors for the clinician to adhere to the guidelines.CONCLUSIONS: After introduction of national recommendations for antibiotic prophylaxis before bone augmentation procedures, the patient group receiving a single preoperative dose decreased while the group not given antibiotic prophylaxis increased. There was no difference in occurrence of postoperative infections between the two time periods. The results indicate a need for educational efforts and strategies for implementation of antibiotic prudence and awareness among surgeons performing bone augmentation procedures.

  • A cross-sectional study on oral health and dental care in intellectually able adults with autism spectrum disorder
  • 2015
  • Ingår i: BMC Oral Health. - : BioMed Central. - 1472-6831 .- 1472-6831. ; 15
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Autism spectrum disorder (ASD) is characterized by impairments in social interaction and communication, restricted patterns of behaviour, and unusual sensory sensitivities. The hypotheses to be tested were that adult patients with ASD have a higher caries prevalence, have more risk factors for caries development, and utilize dental health care to a lesser extent than people recruited from the normal population.Methods: Forty-seven adults with ASD, (25 men, 22 women, mean age 33 years) and of normal intelligence and 69 age-and sex-matched typical controls completed a dental examination and questionnaires on oral health, dental hygiene, dietary habits and previous contacts with dental care.Results: Except for increased number of buccal gingival recessions, the oral health was comparable in adults with ASD and the control group. The group with ASD had less snacking, but also less frequent brushing of teeth in the mornings. The stimulated saliva secretion was lower in the ASD group, regardless of medication. Frequencies of dental care contacts were equal in both groups. The most common reason for missing a dental appointment was forgetfulness in the ASD group.Conclusions: Adults with ASD exhibited more gingival recessions and considerably lower saliva flow compared to healthy controls. Despite equal caries prevalence, the risk for reduced oral health due to decreased salivary flow should be taken into consideration when planning dental care for patients with ASD. Written reminders of dental appointments and written and verbal report on oral health status and oral hygiene instructions are recommended.

  • Polymicrobial synergy stimulates Porphyromonas gingivalis survival and gingipain expression in a multi-species subgingival community
  • 2021
  • Ingår i: BMC Oral Health. - : BioMed Central. - 1472-6831 .- 1472-6831. ; 21:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Dysbiosis in subgingival microbial communities, resulting from increased inflammatory transudate from the gingival tissues, is an important factor in initiation and development of periodontitis. Dysbiotic communities are characterized by increased numbers of bacteria that exploit the serum-like transudate for nutrients, giving rise to a proteolytic community phenotype. Here we investigate the contribution of interactions between members of a sub-gingival community to survival and development of virulence in a serum environment-modelling that in the subgingival pocket.METHODS: Growth and proteolytic activity of three Porphyromonas gingivalis strains in nutrient broth or a serum environment were assessed using A600 and a fluorescent protease substrate, respectively. Adherence of P. gingivalis strains to serum-coated surfaces was studied with confocal microscopy and 2D-gel electrophoresis of bacterial supernatants used to investigate extracellular proteins. A model multi-species sub-gingival community containing Fusobacterium nucleatum, Streptococcus constellatus, Parvimonas micra with wild type or isogenic mutants of P. gingivalis was then created and growth and proteolytic activity in serum assessed as above. Community composition over time was monitored using culture techniques and qPCR.RESULTS: The P. gingivalis strains showed different growth rates in nutrient broth related to the level of proteolytic activity (largely gingipains) in the cultures. Despite being able to adhere to serum-coated surfaces, none of the strains was able to grow alone in a serum environment. Together in the subgingival consortium however, all the included species were able to grow in the serum environment and the community adopted a proteolytic phenotype. Inclusion of P. gingivalis strains lacking gingipains in the consortium revealed that community growth was facilitated by Rgp gingipain from P. gingivalis.CONCLUSIONS: In the multi-species consortium, growth was facilitated by the wild-type and Rgp-expressing strains of P. gingivalis, suggesting that Rgp is involved in delivery of nutrients to the whole community through degradation of complex protein substrates in serum. Whereas they are constitutively expressed by P. gingivalis in nutrient broth, gingipain expression in the model periodontal pocket environment (serum) appeared to be orchestrated through signaling to P. gingivalis from other members of the community, a phenomenon which then promoted growth of the whole community.

  • Patient-reported negative experiences related to caries and its treatment among Swedish adult patients.
  • 2017
  • Ingår i: BMC Oral Health. - : BioMed Central (BMC). - 1472-6831 .- 1472-6831. ; 17:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: It has been suggested that dental caries should be regarded as a chronic disease as many individuals repeatedly develop new caries lesions. How this is perceived by caries active patients is unclear. The aim of this study was to measure patient-reported attitudes and negative experiences related to caries and dental treatment.METHODS: A questionnaire was mailed to 134 caries active (CA) and 40 caries inactive (CI) adult patients treated at a Swedish public dental service clinic. The questionnaire included items regarding patient-reported oral health; attitudes towards caries and efforts to prevent them; and negative experiences related to caries and dental treatment. Questionnaire data were supplemented with data on caries and caries prophylaxis from patients' dental records. Exploratory factor analysis was conducted on items related to patients' perceptions of problems to see whether scales could be created. Experiences, perceptions and dental records of CA and CI patients were compared.RESULTS: The overall response rate was 69%. Dental records confirmed that CA patients had significantly more decayed teeth per year and a longer period of caries-active time than CI patients. Factor analysis resulted in 3 distinct scales measuring problems related to caries; 1) caries-related information; 2) negative experiences; and 3) negative treatment/staff attitudes. A fourth scale measuring perceived problems related to caries was also created. The CA group reported significantly more problems related to caries and dental treatment, received significantly more caries-related information, and reported significantly more negative treatment experiences compared to CI patients.CONCLUSIONS: Caries prophylaxis methods need to be improved in order to better meet the needs of caries active patients and to create a more positive experience with dental care.

  • Inequality in oral health related to early and later life social conditions : a study of elderly in Norway and Sweden
  • 2015
  • Ingår i: BMC Oral Health. - : Springer Science and Business Media LLC. - 1472-6831 .- 1472-6831. ; 15
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: A life course perspective recognizes influences of socially patterned exposures on oral health across the life span. This study assessed the influence of early and later life social conditions on tooth loss and oral impacts on daily performances (OIDP) of people aged 65 and 70 years. Whether social inequalities in oral health changed after the usual age of retirement was also examined. In accordance with "the latent effect life course model", it was hypothesized that adverse early-life social conditions increase the risk of subsequent tooth loss and impaired OIDP, independent of later-life social conditions.Methods: Data were obtained from two cohorts studies conducted in Sweden and Norway. The 2007 and 2012 waves of the surveys were used for the present study. Early-life social conditions were measured in terms of gender, education and country of birth, and later-life social conditions were assessed by working status, marital status and size of social network. Logistic regression and Generalized Estimating Equations (GEE) were used to analyse the data. Inverse probability weighting (IPW) was used to adjust estimates for missing responses and loss to follow-up.Results: Early-life social conditions contributed to tooth loss and OIDP in each survey year and both countries independent of later-life social conditions. Lower education correlated positively with tooth loss, but did not influence OIDP. Foreign country of birth correlated positively with oral impacts in Sweden only. Later-life social conditions were the strongest predictors of tooth loss and OIDP across survey years and countries. GEE revealed significant interactions between social network and survey year, and between marital status and survey year on tooth loss.Conclusion: The results confirmed the latent effect life course model in that early and later life social conditions had independent effects on tooth loss and OIDP among the elderly in Norway and Sweden. Between age 65 and 70, inequalities tooth loss related to marital status declined, and inequalities related to social network increased.

  • Eating disorders : knowledge, attitudes, management and clinical experience of Norwegian dentists
  • 2015
  • Ingår i: BMC Oral Health. - : BioMed Central (BMC). - 1472-6831 .- 1472-6831. ; 15
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The purpose of this study was to investigate knowledge, attitudes and clinical experience with regard to patients with eating disorders (ED) among Norwegian dentists. Methods: In 2010, a questionnaire was sent to all dentists in Norway (N = 4282) comprising 33 questions related to demographics of the participating dentists, their knowledge of ED (general and oral health aspects), clinical experience, attitudes and perceived management preferences. Results: The participation rate was 40 % (47 % women and 53 % men). Their knowledge about ED was often retrieved from common media sources and the greater part of the participants reported they had seen very few patients with ED during their professional career. Female dentists reported superior knowledge about ED compared to males, but the former experienced greater difficulties to inform about the condition. Referrals of the patient to other health facilities were significantly more common among female compared to male dentists. The majority of dentists (76 %) reported a need of more education related to ED management. Conclusions: The Norwegian dentists in this study reported limited clinical experience and insufficient knowledge regarding ED. There is therefore a need to increase both undergraduate and continuing education in this field, which can improve preventive and management measures that a dentist can provide for ED patients.

  • Health-related quality of life and prospective caries development
  • 2016
  • Ingår i: BMC Oral Health. - : BioMed Central. - 1472-6831 .- 1472-6831. ; 16
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The present study was conducted to prospectively assess the association between health-related quality of life (HRQoL) and the development of dental caries in adults in northern Sweden. The SF-36 questionnaire was used to estimate HRQoL.Methods: Adults who had (i) participated in a population-based health screening in northern Sweden between 2003 and 2009 and had completed the SF-36 questionnaire, and (ii) received a dental check-up within 1 year (n = 15,615) were included in the study. Of these, 9,838 had a second caries examination 2-7 years after the baseline recording. Information regarding SF-36, lifestyle factors and medical conditions was retrieved by questionnaires, and anthropometric status and blood lipid levels were measured. The association between dental caries (outcome) and SF-36 scores (exposure) with the inclusion of potential confounders was analysed by linear and logistic regression.Results: Caries increment increased significantly with decreasing scores for both physical and mental dimensions of SF-36 in women, but no association was seen in men. However, lifelong caries experience (DMFS) increased linearly with decreasing physical HRQoL in both men and women; this was also observed for the single dimension of mental HRQoL. The crude odds ratio for being in the highest caries quintile compared to the lowest when having the poorest physical HRQoL compared with the best physical HRQoL was 1.88 (95 % CI: 1.54-2.3). Several factors were identified as potential confounders in the associations between DMFS and SF-36 scores, including education level, smoking, age, medications, higher levels of total cholesterol, triglycerides, systolic blood pressure, body mass index and sugar intake. Except for education level and smoking, the effect sizes for the association between gradually decreasing SF-36 scores and increasing caries were generally moderate.Conclusions: Increased development of caries was associated with low physical HRQoL and some aspects of mental HRQoL. The mechanisms underlying these associations, which are likely confounded by both biological and lifestyle factors, remain to be elucidated. The study implies that, when possible, subjects with poor HRQoL would benefit from caries prevention measures meeting the underlying situation.
