A brief motivational interviewing as an adjunct to periodontal therapy-A potential tool to reduce relapse in oral hygiene behaviours. A three-year study.

OBJECTIVES: To evaluate (ii) whether inclusion of a single motivational interviewing (MI) session, as an adjunct to periodontal therapy, might be beneficial for preventing relapse in oral hygiene behaviours among patients treated for chronic periodontitis and (ii) whether individual and clinical characteristics can be of predictive value for retention of sufficient oral hygiene behaviours. MATERIAL & METHODS: This 3-year follow-up of a previously reported randomized controlled trial (RCT) study of 6-month duration included 26 patients. Patients in the test group had received one MI session by a clinical psychologist before initiation of the periodontal treatment. Otherwise, all patients followed the same treatment protocol for conventional educational intervention and non-surgical periodontal therapy. Efficacy variables assessed for evaluation of the standard of self-performed periodontal infection control were marginal bleeding index (MBI; primary efficacy variable) and plaque score (PI). RESULTS: The patterns of change in MBI and PI scores were similar for test and control groups over the observation period. At 3 years, both groups showed a desirable mean full-mouth MBI of 15%, a figure that was comparable to that at the short-term evaluation after active periodontal treatment. The post-treatment MBI was the only variable identified as a predictor of retained adequate oral hygiene behaviours. CONCLUSION: A single MI session as an adjunct to conventional periodontal therapy could not be proven to be of long-term beneficial additive effect with regard to prevention of relapse in oral hygiene behaviour. Desirable standard of self-performed infection control after active periodontal treatment predicted the retention of sufficient oral hygiene behaviour over time.

Professional competencies and work-related support in relation to periodontal therapy and work satisfaction: A questionnaire study among Swedish Dental Hygienists.

OBJECTIVES: To analyse dental hygienists' (DHs) views on professional competencies and behavioural interventions in the treatment of periodontitis patients, perceived work-related support and work satisfaction. METHODS: A Web-based questionnaire was distributed to all DHs employed at the public dental service in the county of Västra Götaland, Sweden. 302 (83%) responded to the questionnaire; 291 of these DHs stated that they on regular basis treated periodontitis patients and thus constituted the sample for analyses. Based on initial correlation and bivariate analyses of the questionnaire data, multiple logistic regression models were formulated to estimate perceived competencies to treat patients with periodontitis and work satisfaction. RESULTS: The multiple analyses revealed that DHs who worked with specific methods for behavioural intervention, like motivational interviewing, were more likely to rate themselves as "definitely possessing the competencies required to treat patients with periodontitis" (OR 4.0). Likewise, this group of DHs did not consider it more difficult to charge their patients the financial costs for such a behavioural intervention than for scaling therapy (OR 3.1). The perception that one's professional competencies were utilized well in daily practice was associated with high work satisfaction (OR 4.1). More years in the profession (OR 1.03) and a good support by colleagues (OR 1.9) had also a positive impact on work satisfaction. CONCLUSIONS: Dental hygienists' considered that competencies in the treatment of periodontitis patients were related to the practice of behavioural interventions as part of therapy. A stimulating and supportive work environment, with opportunities for professional development, is important for work satisfaction.

Oral health-related resources - a salutogenic perspective on Swedish 19-year-olds.

The aim was to explore health-oriented resources among 19-year-olds and, specifically, how these resources interact with oral health-related attitudes and behaviour. To represent individuals with various psychosocial environments and socioeconomic areas, the participants were selected from different geographical locations of the Public Dental Service clinics in the county of Jönköping, Sweden. A structured questionnaire was distributed, including the instrument 'sense of coherence', for description of the study group, followed by a semi-structured thematized interview. The qualitative method used for sampling and analyses was grounded theory. Data sampling and analysis were performed in parallel procedures and ended up in a sample of ten informants (five women). In the analysis of interview data, a core category was identified, 'Resources of Wealth and Balance in Life - a Foundation for Healthy Choices', describing the central meaning of the informants' perceptions of resources with an essential beneficial impact on oral health. The core category was built on five themes, which in turn had various subthemes, describing different dimensions of resources interacting with beneficial oral health-related attitudes and behaviour: 'Security-building Resources and Support', 'Driving force and Motivation', 'Maturity and Insight', 'Health Awareness' and 'Environmental influences.' The results elucidate personal and environmental health-oriented resources with influence on oral health-related attitudes and behaviours of young individuals. Such beneficial recourses should be recognized by dental personnel to promote oral health.

The influence of epigenetics in relation to oral health.

The immune response is influenced by genetic and epigenetic factors, as well as disease and environmental factors. The term 'epigenetics' describes changes in the genome that influence the gene expression without altering the DNA sequence. In contrast to genetic changes in the DNA, epigenetic changes are reversible and are influenced by environmental factors. The aim of this study is to review the literature on epigenetic modifications with respect to oral health and inflammatory conditions in the oral cavity and to discuss the potential use of this new research field for the dental hygienists' and/or dentists' clinical work. Relevant publications were identified using the PubMed database without limits. The searches were conducted during January to March 2012 and resulted in articles published between 1912 and 2012. Key factors such as environment, diet, smoking, bacteria and inflammation were identified to be relevant to oral health. The result of this review article shows that there is a void in the research on epigenetics in relation to oral health. Identification of epigenetic modifications correlating with oral health may not only present a link between the influence of genetics and that of the environment on oral diseases but also provide new treatment models and tools for the dental professionals.

Evaluation of the Dental Hygienist Beliefs Survey; test-retest assessment in a group of general dental patients.

OBJECTIVE: To evaluate the Dental Hygienist Beliefs Survey (DHBS) and the test-retest reliability of DHBS in a group of general dental patients. MATERIAL AND METHODS: The DHBS, which is a questionnaire constructed to assess patients' specific attitudes towards dental hygienists (DHs), was distributed together with the Dental Anxiety Scale adapted to specifically assess fear of DH treatment (DHAS). It was hypothesized that DHBS would correlate with DHAS and gender. The questionnaires were consecutively distributed to 80 patients at their first visit and after a clinical examination performed by a DH student. Retest assessments of DHBS were conducted approximately two weeks later in conjunction with the next visit at the DH student and before treatment (scaling session). The final study sample included 77 adult general dental patients in treatment at an education clinic for DH students. RESULTS: The results verified a statistically significant correlation between DHBS and DHAS. The DHBS sum of scores showed high internal consistency with Cronbach's a coefficient of 0.88 and 0.91 at the first and second assessments, respectively, and the test-retest reliability of the DHBS was acceptable with intraclass correlation coefficient of 0.76. No statistically significant association was found between DHBS and gender. CONCLUSION: The results suggest that the DHBS is a reliable and stable scale to use to assess patients' specific attitudes towards DHs. Moreover, DH beliefs are associated with fear of DH treatment.

Dental hygienists' views on communicative factors and interpersonal processes in prevention and treatment of periodontal disease.

OBJECTIVE: The aim of this study was to explore views of DHs on communicative issues and interpersonal processes of importance in the prevention and treatment of periodontal disease. METHOD: The qualitative method of Grounded Theory (GT) was chosen for data sampling and analysis. Audio-taped and open-ended interviews were conducted with 17 dental hygienists. The interviews were transcribed verbatim and analysed in a hierarchical coding process, according to the principles of GT. RESULT: In the analysis a core category was identified as 'to be successful in information and oral health education and managing desirable behavioural changes'. The core concept was related to four additional categories and dimensions; (i) 'to establish a trustful relationship with the patient', (ii) 'to present information about the oral health status and to give oral hygiene instructions', (iii) 'to be professional in the role as a dental hygienist' and (iv) 'to have a supportive working environment in order to feel satisfaction with the work and to reach desirable treatment results'. CONCLUSION: The results describe a psychosocial process that elucidates the importance of building a trustful relationship with the patient, feeling secure in one's professional role as a DH and last but not least, the importance of having support from colleagues and the clinical manager to be successful in the prevention and treatment of periodontal diseases.

Dental beliefs, patients' specific attitudes towards dentists and dental hygienists: a comparative study.

Interpersonal relationships are important for communication, oral health education and patients' satisfaction with dental care. To assess patients' attitudes towards dental caregivers, a Swedish version of the revised Dental Belief Survey (DBS-R) and a comparable and partly new instrument the Dental Hygienist Belief Survey (DHBS) have been evaluated. The aim of the present study was to investigate if patients' attitudes towards dental hygienists (DH) and dentists (D) differ with regard to the separate items in DBS-R and DHBS. The study was a comparative cross-sectional study with 364 patients (students, general patients and patients with periodontal disease). All patients completed the DBS-R and DHBS surveys. The overall pattern in the results showed that participants in general had a less negative attitude towards DH when compared with that towards D. This was most pronounced among students and least pronounced among patients with periodontal disease. No statistically significant difference could be found in items with regard to feelings of shame and guilt in dental care situations, indicating that these items were rated on a more negative level also for DH. The conclusion is that participants had a less negative attitude towards DH with the exception of situations which may give rise to feelings of shame and guilt, an important finding for future dental hygiene care.

Complications of clean intermittent catheterization in young females with myelomeningocele: 10 to 19 years of followup.

PURPOSE: We evaluated the rate of complications associated with catheterization and the risk of urethral lesions in girls with myelomeningocele treated with clean intermittent catheterization for a minimum of 10 years. MATERIALS AND METHODS: We examined the medical records of 31 females with myelomeningocele followed from the start of clean intermittent catheterization until age 11 to 20 years. Catheterization had been performed for a median of 15 years (range 10 to 19). Altogether, catheterization was used for a total of 459 patient-years. Noncoated polyvinyl chloride catheters were used in all cases. Anticholinergic treatment was given during 176 of the patient-years. RESULTS: Complications of catheterization were recorded in 13 patients on 20 occasions. Macroscopic hematuria was seen in 4 individuals. In 2 patients the hematuria was caused by urethral polyps that were cured by resection. Difficulties with catheterization occurred in 12 patients. The problems were solved by temporary use of lubrication or by other minor changes in management. There were no difficulties recorded after puberty. The risk of difficulties at catheterization doubled with the use of a Ch8 to Ch10 catheter compared to a Ch12 or larger catheter, and doubled during assisted clean intermittent catheterization compared to clean intermittent self-catheterization. CONCLUSIONS: There were remarkably few problems associated with clean intermittent catheterization in these females with myelomeningocele, despite long treatment periods and use of noncoated polyvinyl chloride catheters. Clean intermittent self-catheterization and large size catheters were associated with few complications.

Attitudes to dental hygienists: evaluation of the Dental Hygienist Beliefs Survey in a Swedish population of patients and students.

The aim was to evaluate and test the psychometric properties of the Dental Hygienist Beliefs Survey (DHBS) in a Swedish sample of different patient groups and students. It was hypothesized that negative dental hygienist beliefs would discriminate between fearful and non-fearful study groups. The DHBS was distributed together with the revised Dental Beliefs Survey (DBS-R) and the Dental Anxiety Scale (DAS). The study sample included 394 subjects (130 students, 144 general dental patients, 90 periodontal patients and 30 patients on a waiting list for dental fear treatment). The results verified that the DHBS discriminates well between dentally fearful and non-fearful study groups. The DHBS had high internal consistency (Cronbach's alpha = 0.96-0.98) in all the groups. The correlation between the DHBS and the DBS-R was high (rho = 0.82, P < 0.001). Furthermore, the DHBS correlated significantly with the DAS, as well as with a low but significant correlation to age (more negative attitudes in younger age groups) and gender (more negative attitudes amongst women). Regression analysis showed that gender and the DHBS items: 23, 16 and 28, i.e. items related to feeling helpless, worries/fears not being taken seriously and fear about 'bad news' possibly preventing treatment, were the most important predictors of dental fear. The results suggest that the DHBS may be a valid and reliable scale to use in order to assess patient's specific attitudes to dental hygienists. However, the psychometric properties including test-retest analysis and the underlying factor structure of the DHBS need to be further explored.

Psychosocial aspects of dental and general fears in dental phobic patients.

Phobic reactions can often be a significant health problem for fearful dental patients. This is true in particular for individuals with long-time avoidance and elevated general psychological distress. The aim of this study was to investigate the expression of dental fear among 67 dental phobic individuals with a low versus high degree of general fear. Reported etiologic background factors, avoidance time, general psychological distress and psychosocial manifestations and consequences of dental phobia were studied. No significant difference in dental anxiety level between individuals with low versus high general fear was found, and both groups reported high frequencies of negative dental experiences. The low-fear group reported a longer (though not statistically significant) average avoidance time than the high-fear group. However, patients with a high level of general fear showed a significantly higher degree of psychological distress, and also reported stronger negative social consequences from their dental anxiety. These results indicate that the character of dental fear might be different between different groups of fearful patients, which makes the condition psychologically handicapping. Such aspects should be assessed in the diagnostic analysis of patients with severe dental anxiety. In particular, assessments of signs of general psychological distress are warranted.

Phobic avoidance and regular dental care in fearful dental patients: a comparative study.

The present investigation was a comparative study of 169 highly fearful dental patients, some of whom received regular dental care (n = 28) and some who never, or only when absolutely necessary, utilized dental care (n = 141). It was hypothesized that phobic avoidance is related to anticipatory stress and anxiety reactions, negative oral health effects, psychological distress, and negative social consequences. Background factors (sex, age, education, and dental attendance pattern), dental anxiety, general fears, general state and trait anxiety, mood states, depression, and quality of life effects were studied. Data were analyzed with descriptive statistics and with exploratory factor and multiple logistic regression analysis. It was shown that dental anxiety is significantly higher among the avoiders and this is in particular evident for anticipatory dental anxiety. Oral health differed between the groups, and it was shown that avoiders had significantly more missing teeth, whereas regular attenders had significantly more filled teeth. The avoiders reported a stronger negative impact on their daily life, whereas there were no significant differences between the groups with regard to general emotions. The logistic regression analysis showed that phobic avoidance was predicted only by anticipated dental anxiety and missing teeth. It was concluded that differences between high dental fear patients with regular dental care and phobic avoidance were mainly related to anticipated fear and anxiety, oral health effects, and concomitant negative life consequences. These results are discussed in terms of subjective stress, negative cognitions, social support, and coping-strategies.
