    Effect of ozone treatment on different cariogenic microorganisms in vitro2008In: Swedish Dental Journal, ISSN 0347-9994, Vol. 32, no 3, p. 139-147Article in journal (Refereed)
    Abstract [en]

    Ozone treatment has been presented and discussed in the literature, as one of the "new" ways to treat dental caries. The aim of this paper was to study the in vitro effect of ozone on some common oral microorganisms related to dental caries using scanning electron microscopy (SEM). The effect of ozone was tested on three different strains of mutans streptococci and one Lactobacillus strain. After exposure of bacteria to ozone treatment for 0 to 60 sec, cultivation on different chair side strips and agar plates took place. Preparation and performance of scanning electron analyses in a field emission scanning electron microscope at 10 kV was then carried out. It was found that gaseous ozone treatment for 20 seconds or more was effective to kill the different microorganisms in vitro. Treatment of 20, 40 and 60 seconds of ozone prevented the bacteria to grow on the different media. Treatment times shorter than 20 seconds resulted in varying results with a limited effect on bacterial growth for treatments of 5-10 sec, respectively. The difference between ozone-treated and untreated specimens was macroscopically readily discernable. None of the strains treated with ozone for 60 seconds showed any bacterial growth. Only samples with untreated bacteria could be found in the SEM analyses in form of large and high colonies. This study presents a clear result of the bactericide effect of ozon (in vitro) on four different strains of bacteria associated with dental caries.

    Tobacco cessation interventions by Swedish dental hygienists: a questionnaire study2012In: Swedish Dental Journal, ISSN 0347-9994, Vol. 36, no 1, p. 45-52Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to investigate tobacco cessation interventions by Swedish dental hygienists and their perception of the importance of tobacco cessation to oral health. A questionnaire was mailed to 400 randomly selected dental hygienists (DH) in Sweden. The questions covered such topics as tobacco cessation interventions, perceived barriers, and their perception of the importance of tobacco cessation in relation to caries, gingivitis, periodontitis and dental implants. The response rate was 57%. Tobacco habits were routinely recorded by 94% of the respondents. 52% of the dental hygienists reported time constraints, 50% reported insufficient competence and 43% answered that they had lack of experience to work with tobacco cessation. All respondents perceived tobacco cessation to be an important determinant of treatment outcomes in patients with dental implants and periodontitis. Bivariate analysis showed an association between training courses in tobacco cessation and tobacco cessation interventions (OR 3.25, CI 95% 1.80-5.85). A logistic multivariate regression model disclosed two other factors significantly correlated with tobacco cessation interventions: competence (OR 2.4, 95% CI 1.16-4.85), and experience (OR 2.1, 95% CI 1.06-4.28). The analyses were adjusted for age, length of undergraduate training course, and dental care organization. The dental hygienists considered tobacco cessation to be very important in patients with periodontitis and in those with dental implants. Most of the DH in this study undertook some tobacco cessation interventions, though not extensive; the main barriers reported were lack of time, competence and experience.

    Measuring oral health from a public health perspective2008In: Swedish Dental Journal, ISSN 0347-9994, Vol. 32, no 3, p. 125-137Article in journal (Refereed)
    Abstract [en]

    The paper aims to analyse measures of oral health-related quality of life (OHQOL) from a Public Health perspective. Twenty-two measures were analysed conceptually as to their mirroring of the Public Health principles: empowerment, participation, holism and equity. Elements of empowerment were found in connection with application of the measures. Participation was found in using lay opinions during development in 12 measures. All measures analysed had elements of a holistic approach so far that they were not wholly biological. Two measures captured positive health effects. Measures were available for all ages, various languages and populations, an element of equity. No measure was wholly compatible with Public Health. They were based on a utilitarian theory not in full accordance with modern health promotion. There is a need to develop measures that more obviously capture the positive aspects of health and health as a process, as well as the personal perspective of oral health.

    Knowledge on periodontal disease before and after a mass media campaign2004In: Swedish Dental Journal, ISSN 0347-9994, Vol. 28, no 4, p. 165-171Article in journal (Refereed)
    Abstract [en]

    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.

    Knowledge of periodontitis and self-perceived oral health: a survey of periodontal specialist patients2013In: Swedish Dental Journal, ISSN 0347-9994, Vol. 37, no 1, p. 49-58Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to investigate changes in knowledge of periodontal disease among patients referred to periodontal specialist clinics. A further aim was to investigate the patients' self- perceived oral health before the treatment. Patients referred to five specialist clinics in periodontology for comprehensive periodontal treatment were consecutive sampled. The study was based on a questionnaire in a before and after design. The first questionnaire was sent to the patients before visiting the specialist clinic and the second was sent after six months. Four questions were analysed, two to measure knowledge about periodontitis and two to measure the patients self- perceived oral health. The first questionnaire was sent by post to 273 patients with a response rate of 31%. The second questionnaire was sent to 85 patients with a response rate of 73%. The results of the study showed a statistically significant improvement of correct answers on the knowledge questions after six months was found for scaling (p = 0.006), X-ray examination (p = 0.001) and increased space between the teeth (p = 0.001). The most frequent self-perceived trouble from the mouth was bleeding gum (70%) and sensitive teeth (51%). In conclusion knowledge of periodontitis improved after visiting the specialist clinic of periodontology. Many of the patients experienced some problems of the mouth.

    A history of frequent dental care reduces the risk of tooth loss but not periodontitis in older subjects2011In: Swedish Dental Journal, ISSN 0347-9994, Vol. 35, no 2, p. 69-76Article in journal (Refereed)
    Abstract [en]

    Objectives: Information on the significance of dental care in older adults is limited. We hypothesized that regular dental visits has an effect on the number of remaining teeth and periodontal conditions in older subjects. Materials and Methods: 1020 randomly selected individuals age 60 - 96 from the Swedish National Study on Aging and Care Blekinge received a comprehensive oral health examination. Results: Dentate women and men had, on average 18.4 teeth (SD +7.6,) and 18.9 teeth (SD + 7.5) respectively (NS). In the youngest group (60 and 66 years old) with less than one dental visit per year, 37 % had >20 teeth, compared with 73 % among those with at least annual visits. Among the old-old, comparable figures were 1.8 % and 37% respectively. Across age groups, bleeding on probing was 23 %. When adjusting for age, and number of teeth GLM univariate analysis failed to demonstrate an effect of dental visit frequency on alveolar bone loss (p = 0.18), the number of periapical lesions (p = 0.65), or the number of endodontically treated teeth ( p = 0.41). Frequent dental visitors had more teeth than infrequent visitors (p = 0.001). Conclusions:Tooth loss and alveolar bone loss severity increase with age. Individuals with regular dental visits retained more teeth but the frequency of dental visits had no impact on plaque deposits, gingival inflammation, or alveolar bone levels.

    Patient satisfaction with dental care in one Swedish age cohort: part 1 - descriptions and dimensions2007In: Swedish Dental Journal, ISSN 0347-9994, Vol. 31, no 2, p. 103-111Article in journal (Refereed)
    Abstract [en]

    The aim of this study were to investigate the dimensionality of satisfaction with dental care, to control the reproducibility of the analysis over time, to investigate changes between the two studied years and to relate satisfaction with elapsed time since the most recent visit to dental care. All persons born in 1942 in two counties in Sweden, Orebro and Ostergotland, were surveyed by post in 1992 at the age of 50 and resurveyed at the age of 55. There were 5363 persons responding at both times, constituting the study group. In this study, opinions are analysed about general satisfaction with dental care and about the most recent dental visit. Factor analysis, one-way ANOVA and contingency tables were used. Overall satisfaction was high both as to general satisfaction and as to the most recent dental care visit. Those with their most recent dental visit more than a year ago felt more pain, anxiety and unpleasantness and were also more generally dissatisfied. Of those having experiences of pain, anxiety and unpleasantness at most recent visit, there was an overrepresentation of non regular attenders. Factor analysis showed that the questions used revealed a stable pattern. In conclusion, the overall satisfaction with dental care was high. Differences between the two studied years were small. Persons not visiting dental care within the last year were more dissatisfied both generally and with the most recent visit. A greater number of regular attenders had no feelings of anxiety, pain or unpleasantness at all.

    Patient satisfaction with dental care in one Swedish age cohort: part II - what affects satisfaction2007In: Swedish Dental Journal, ISSN 0347-9994, Vol. 31, no 3, p. 137-146Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to investigate satisfaction with dental care in relation to dental care factors, recent dental care experiences, past dental care experiences, general health factors, oral health factors and socio-economic factors and all over time. All persons born in 1942 in two counties in Sweden, Orebro and Ostergötland, were surveyed by post in 1992 at the age of 50, and resurveyed at the age 55. There were 5363 persons responding at both times, constituting the study group. A conceptual theoretical model was constructed to be used as a framework in the analysis. Multiple regression analysis and contingency tables were used. Factors related to satisfaction with dental care were: care organisation, cost for care, visit to dental specialist, time spent in waiting room, regular attendance, reception at dental clinic, feelings of anxiety, taking part of school dentistry, smoking, oral health factors, dental appearance and being dissatisfied 5 years previously. Change between the two study years was affected by perceived oral health, experiences from the most recent dental visit and care organisation. Oral health related factors and dental care factors like cost for care and care organisation were related to satisfaction with dental care. Likewise were experiences from the most recent dental visit and to some extent past care experiences like school dentistry. Almost no correlation was seen between socio-economic factors and satisfaction.

    Cross-cultural adaptation and validation of the Oral Impacts on Daily Performances OIDP) in Swedish2008In: Swedish Dental Journal, ISSN 0347-9994, Vol. 32, no 4, p. 187-195Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: The aim was to assess the validity and reliability of a Swedish version of the Oral impacts on Daily Performance (OIDP) index measuring oral health-related quality of life. MATERIAL AND METHODS: After translation and cultural adaptation, a 3-site sample of 204 adults (20-86 years) was interviewed using the OIDP. Moreover, the study included a self-administered questionnaire and a clinical examination. RESULTS: A total of 39.7% reported at least one oral impact on daily life. The most common performances affected were eating and cleaning teeth (both 20.6%). Oral effects on psychological performances caused the highest impacts. No gender or age differences were demonstrated with respect to having at least one impact. However, among those affected, women, old and young subjects scored higher than men and other ages, respectively, on the OIDP. The face and content validity were deemed good in pilot interviews with laypersons and dental professionals. The construct validity was confirmed, as the OIDP score was consistently associated with self-perceived oral health OR 2.13 (95% CI 1.10-4.10) and other self-rated variables, e.g. satisfaction with oral health OR 2.43 (CI 1.34-4.41), also when accounting for age, gender and socioeconomic differences. Associations were estimated using logistic regression. Lacking 10 or more teeth was associated with a higher OIDP score, which supports the criterion validity of the instrument. In a test-retest analysis Cohen's kappa was 0.77. CONCLUSIONS: The Swedish version of the OIDP appears to be a valid and reliable measure for assessing oral impacts on daily performances.
