    • <p><strong>Purpose:</strong></p><p>The aim of the study was to explore and gain an understanding of patients' views on their periodontal conditions, their perceived impact of periodontitis on daily life, as well as their attitudes to oral health and expectations of treatment.</p><p><strong>Materials and Methods:</strong></p><p>The study subjects were patients with chronic periodontitis, who had been referred to a specialist clinic. The constant comparative method for grounded theory was used to collect and analyse the data. Audiotaped, open-ended interviews were conducted after periodontal examination, but before treatment. The interviews were transcribed verbatim and consecutively analysed in hierarchical coding processes and continued until saturation was reached (n = 17). In the analysis, a conceptual model that outlined the steps involved in the diagnosis of periodontitis was generated. The core concept of the model, keeping up appearance and self-esteem, was related to the following four additional categories and their dimensions; doing what you have to do trying to live up to the norm, suddenly having a shameful and disabling disease, feeling deserted and in the hands of an authority, and investing all in a treatment with an unpredictable outcome.</p><p><strong>Results:</strong></p><p>The results illustrated that subjects diagnosed with chronic periodontitis felt ashamed and were willing to invest all they had in terms of time, effort and financial resources to become healthy and to maintain their self-esteem. However, they perceived a low degree of control over treatment decisions and treatment outcome.</p><p><strong>Conclusions: </strong></p><p>The results demonstrate the vulnerability of patients diagnosed with chronic periodontitis and emphasise the importance of communication in dentistry.</p>

    • <p><strong>OBJECTIVES:</strong> To assess the effects of an experimental 0.454% stannous fluoride (SnF2) dentifrice on the oral sulcular microbiota in patients with various stages of oral diseases using checkerboard DNA-DNA hybridization.</p><p><strong>MATERIAL AND METHODS:</strong> In the present one-month, single center, single product, prospective cohort trial, 37 adults (mean age 37.6) were assigned to one of four oral health condition cohorts with seven to 10 subjects each: 1. mild gingivitis, 2. marked generalized gingivitis to moderate periodontitis, 3. caries-prone and 4. treated moderate to advanced chronic periodontitis in supportive periodontal care. All four groups were asked to use the test dentifrice and a power toothbrush twice a day for one minute during a four-week test period. Before and after the trial period, Plaque Indices (PII, Silness and Löe, 1964) and Gingival Indices (GI, Löe and Silness, 1963) were recorded. Subgingival plaque samples were collected from all patients at Baseline, as well as after two and four weeks. These samples were analyzed for content of 40 bacterial species using checkerboard DNA-DNA hybridization.</p><p><strong>RESULTS:</strong> As a result of the only one minute brushing with the stannous fluoride dentifrice, the mean PII at Baseline was significantly lower (p &lt; 0.05) from the mean PII at four weeks. No statistically significant differences were found between premolar and molar mean values. Moreover, no statistically significant differences were found between the mean GI at Baseline and at four weeks. The microbiological analysis showed that at baseline subjects in groups 2 and 4 had significantly higher bacterial loads of bacteria than groups 1, and 3 (i.e. A. actinomyctemcomitans P. gingivalis, T. forsythia, and T. denticola. Over the study period, the total bacterial load did not change in groups 2, 3 and 4. In groups 1 and 3, however, an increase in the loads of Streptococci spp. were noticed (p &lt; 0.05) including S. mitis, S. intermedius, and S. sanguis (p &lt; 0.01) suggesting an increase in the presence of early colonizing and health associated bacteria.</p><p><strong>CONCLUSION:</strong> One minute brushing with a 0.454% stannous fluoride dentifrice did--after four weeks--not affect the subgingival microbial profiles in patients with moderate periodontitis and treated moderate to advanced periodontitis. However, the sulcular microbial profiles of mild gingivitis and caries-prone patients were affected, indicating a shift towards a gingival health associated microbiota in the sulcular region of patients not affected by attachment loss.

  • Screening for Oral Dryness in Relation to Salivary Flow Rate Addresses the Need for Functional Tests of Saliva
  • 2010
  • Ingår i: Oral Health & Preventive Dentistry. - Quintessence. - 1602-1622 .- 1757-9996. ; 8:3, s. 243-252

    • <p>Purpose: The aim of the present study was to assess the occurrence of reported subjective oral dryness in relation to objective sialometric values in a randomly selected group and a dental care seeking group. Materials and Methods: A questionnaire assessing subjective oral dryness was sent out to a randomly selected sample of 200 individuals. The dental care seeking group was recruited from among patients attending the Faculty of Odontology, Malmö University. A total of 200 patients were asked to participate in the present study. In total, of 312 individuals (78%) who completed the survey, 157 agreed to participate in the complementary clinical examination that included measures of salivary flow rate. Results: The reported subjective oral dryness was 20% and 28.6% for the randomly selected group and the dental care seeking group, respectively. No statistically significant differences were found between the two study populations with regard to percentage of reported subjective oral dryness, and stimulated and unstimulated salivary flow rates (P > 0.05). In the dental care seeking group, individuals reporting subjective oral dryness presented ‘a small degree of abrasion in the dentine in the incisor region’ to a greater extent (P < 0.05). No statistically significant association between subjective oral dryness and unstimulated and stimulated salivary flow rates was found in either of the studied populations (P > 0.05). Individuals identified with subjective or objective oral dryness presented to a greater extent a history of oral rehabilitation compared to individuals who showed no indication of oral dryness. Conclusions: No association between sialometric measures and subjective report of oral dryness was found in the present study.</p>

  • Minimally invasive dentistry : concepts and techniques in cariology
  • 2003
  • Ingår i: Oral Health & Preventive Dentistry. - 1602-1622 .- 1757-9996. ; 1:1, s. 59-72

    • <p>The concept ‘Minimally Invasive Dentistry’ can be defined as maximal preservation of healthy dental structures. Within cariology, this concept includes the use of all available information and techniques ranging from accurate diagnosis of caries, caries risk assessment and prevention, to technical procedures in repairing restorations. Dentists are currently spending more than half their time replacing old restorations. The main reasons for restoration failures are secondary caries and fractures, factors that are generally not addressed in the technical process of replacing a restoration. Prevailing concepts on minimally invasive dentistry seem to be ‘product or technique-motivated’, challenging one technique or product with another, rather than focusing on a general concept. New knowledge of caries progression rates has also led to substantial modification of restorative intervention thresholds and further handling of the disease. New diagnostic tools for caries lesion detection, caries risk assessment and focused preventive treatments have decreased the need for early restorative interventions. In parallel to this, new techniques for cutting teeth and removing decay have evolved. This paper focuses on describing minimally invasive dentistry in cariology from a conceptual perspective, relating to clinical caries diagnosis, restorative intervention thresholds and operative procedures, with special reference to survival of tunnel and slot restorations and to repair vs. replacement of defective restorations.</p>

  • What is Minimally Invasive Dentistry?
  • 2004
  • Ingår i: Oral Health & Preventive Dentistry. - 1602-1622 .- 1757-9996. ; 2:Suppl 1, s. 287-292
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • <p>Minimally Invasive Dentistry is the application of "a systematic respect for the original tissue." This implies that the dental profession recognizes that an artifact is of less biological value than the original healthy tissue. Minimally invasive dentistry is a concept that can embrace all aspects of the profession. The common delineator is tissue preservation, preferably by preventing disease from occurring and intercepting its progress, but also removing and replacing with as little tissue loss as possible. It does not suggest that we make small fillings to restore incipient lesions or surgically remove impacted third molars without symptoms as routine procedures. The introduction of predictable adhesive technologies has led to a giant leap in interest in minimally invasive dentistry. The concept bridges the traditional gap between prevention and surgical procedures, which is just what dentistry needs today. The evidence-base for survival of restorations clearly indicates that restoring teeth is a temporary palliative measure that is doomed to fail if the disease that caused the condition is not addressed properly. Today, the means, motives and opportunities for minimally invasive dentistry are at hand, but incentives are definitely lacking. Patients and third parties seem to be convinced that the only things that count are replacements. Namely, they are prepared to pay for a filling but not for a procedure that can help avoid having one.</p>

  • Aciduric Bacterial Communities at Three Levels in Dentin Caries
  • 2013
  • Ingår i: Oral Health & Preventive Dentistry. - Quintessence. - 1602-1622 .- 1757-9996. ; 11:4, s. 359-367
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Purpose: Dentin caries constitute a complex ecosystem with a diverse microbiota adapted to fluctuations in nutrient concentration and acidity. However, knowledge about the acid tolerant microbiota at different levels in the lesion is rather poor. Hence, the purpose of this study was to investigate the acid tolerant microflora at different levels in established dentin caries lesions using solid pH-selective media. Materials and Methods: Primary dentin caries lesions were sampled with a bur at three levels (superficial, centre and the clinically caries-free floor of the lesion) in 10 patients. Samples were incubated on pH-neutral and pH-selective (pH 4.0, 4.5, 5.0, 5.5) agars. Numbers of colony-forming units (cfu) were determined and colonies were subsequently characterised morphologically and isolated. Results: The total number of bacteria in the carious lesions, recovered using blood agar (BA), ranged from 5.88 x 103 to 5.85 x 105 (median 2.64 x 105; range 5.80 x 105) and numbers of recovered bacteria decreased with decreasing agar pH. Fewer bacteria were found in the clinically caries-free dentin (P = 0.042), but the mean number of cfu (BA) was still 5.88 x 103 in those samples. Conclusion: Each of the 10 investigated dentin caries lesions harboured a unique microbial flora, indicating that various combinations of aciduric bacteria can colonise, survive in and probably propagate dentin caries. Solid pH-selective agars can be used successfully to select acid-tolerant microorganisms in dentin caries lesions. This could be used to describe this subset of the total microbiome from a phenotypic point of view, an objective that cannot be accomplished using molecular methods.</p>

  • The impact of behavioural interventions on young people's attitudes toward tobacco use.
  • 2010
  • Ingår i: Oral Health & Preventive Dentistry. - 1602-1622 .- 1757-9996. ; 8:1, s. 23-32
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: The objective of the present study was to study the ability to influence young at-risk patients' attitudes toward tobacco use through two intervention methods that were performed by dental health professionals. MATERIALS AND METHODS: Two interventions, a brief individual motivational interview and an adapted school lecture, were studied, and both were compared with a control group. Before and after interventions, a questionnaire was used. Patients born in 1989 and 1992 who were judged by the dental personnel as potentially at risk for dental diseases, a total of 301 individuals, were included. RESULTS: Both before and after interventions, the results showed a generally negative attitude towards tobacco use. A majority of the participants were positive towards measures that were taken to control the spread of tobacco use, younger participants (born 1992) to a greater extent (73%) than the older participants (born 1989) (54%). Important factors that kept the participants away from tobacco use were the harmful effects and the approaches of parents and friends. The older participants believed to a greater extent that they would try smoking as adults. No change in tobacco use was registered after intervention, although the participants reported an increased use among friends. CONCLUSIONS: The two pedagogical methods that were used in the present study influenced the young people's attitudes towards tobacco use only to a small extent. However, the period between 12 and 15 years old seems to provide a good opportunity to influence attitudes towards tobacco. The adolescents' demand for interactive learning and their development of attitudes and tobacco use habits in relation to family and friends provide opportunities to use new pedagogical models.
