Abstract
PURPOSE Although overall success rates for treating obstructive sleep apnea (OSA) with an oral appliance (OA) are high, they are significantly higher among females. To verify published data, the study's purpose was to evaluate a participant sample after one year of OA use. The primary outcome was treatment response, with responders defined as having an apnea-hypopnea index (AHI) < 10 at follow-up and/or reduced by ≥50% of baseline. Secondary measures were from standardized questionnaires. METHODS A sample of 314 participants, predominately with moderate-to-severe OSA, were enrolled and instructed to use an OA every night. At baseline and one-year follow-up, polygraphic recordings and questionnaires, including sleepiness (measured using the Epworth sleepiness scale) and quality-of-life (measured using the Functional Outcomes of Sleep Questionnaire), were collected. RESULTS Among the 314 participants, 192 completed the one-year evaluation: 51 females (27%) and 141 males (73%). Overall, OA treatment resulted in 78% and 77% responders among females and males, respectively. Neither the difference in improvement nor the absolute change in AHI differed significantly based on gender, at any OSA severity level. There were no significant gender differences in sleepiness or quality of life. Treatment-related adverse reactions were more common among females. CONCLUSION Both females and males with OSA respond well to OA therapy, with nonsignificant gender differences in outcomes. Thus, the hypothesis that females respond better to OA treatment is rejected.

Abstract
INTRODUCTION Oral appliance (OA) therapy in obstructive sleep apnea (OSA) could be a risk factor for normal jaw function, given the prolonged effect of an OA in keeping the mandible in a protruded position away from a normal position. This study aimed to assess changes in symptoms and clinical findings related to jaw function after 1 year of treating OSA with an OA. METHODS In this follow-up clinical trial, 302 patients with OSA were assigned to treatment with either monobloc or bibloc OA. Baseline and 1-year follow-up assessment included using the Jaw Functional Limitation Scale, self-reported symptoms and signs related to jaw function. The clinical examination of jaw function included mandibular mobility, dental occlusion, and tenderness in the temporomandibular joints and masticatory muscles. Descriptive analyses of variables are presented for the per-protocol population. To evaluate differences between the baseline and the 1-year follow-up, paired Student t tests and the McNemar change test was used. RESULTS One-hundred and ninety-two patients completed the 1-year follow-up (male 73%, mean aged 55 ± 11 years). There was no change in the Jaw Functional Limitation Scale score at the follow-up (nonsignificant). The patients described no change in symptoms at the follow-up, except for improvements in morning headache (P <0.001) and increased frequency of difficulties in opening the mouth or chewing on awakening (P = 0.002). Subjectively reported changes in dental occlusion during biting/chewing increased significantly at the follow-up (P = 0.009). CONCLUSIONS No changes in measurements of jaw mobility, dental occlusion, or pain on palpation of the temporomandibular joints or masticatory muscles were seen at the follow-up. Thus, using an OA in treating OSA had limited influence on jaw functions and related symptoms. Moreover, the risk of developing pain and functional impairment in the masticatory system was infrequent, indicating that this treatment is safe and can be recommended.

Abstract
OBJECTIVE The aim was to identify caries active individuals among adults by using a trajectory model of longitudinal data from the Swedish national registry (SKaPa) and comparing them with published data from the Dunedin cohort. MATERIALS AND METHODS Data from two different age groups (30- and 40-year-olds) followed for 10 years were retrieved from SKaPa and were compared with published longitudinal birth-cohort data from the Dunedin study. Using the trajectory model, the subjects were divided into three different trajectories according to their caries development over time (i.e. high, 15%; moderate, 45%; low, 40%). RESULTS Caries experience, as measured by mean decayed, missing, and filled surfaces (DMFS) index, revealed significant differences among the three trajectories in both age groups. The patterns were similar to those observed in the Dunedin cohort. The mean increase in DMFS during the 10-year follow-up period from SKaPa was significantly higher for the high trajectories in both age groups compared with the moderate and low trajectories. CONCLUSIONS The method using three trajectories for presentation of caries experience over time, may be a useful tool to identify subjects with different disease activities. Identification of subjects in the high caries experience trajectory may increase the possibility to explore and evaluate more effective caries prevention for this group in the future.

Abstract
INTRODUCTION This paper describes the development of "Swedish Guidelines for OSA treatment" and the underlying managed care process. The Apnea Hypopnea Index (AHI) is traditionally used as a single parameter for obstructive sleep apnea (OSA) severity classification, although poorly associated with symptomatology and outcome. We instead implement a novel matrix for shared treatment decisions based on available evidence. METHODS A national expert group including medical and dental specialists, nurses, and patient representatives developed the knowledge-driven management model. A Delphi round was performed amongst experts from all Swedish regions (N = 24). Evidence reflecting treatment effects was extracted from systematic reviews, meta-analyses, and randomized clinical trials. RESULTS The treatment decision in the process includes a matrix with five categories from a "very weak"" to "very strong" indication to treat, and it includes factors with potential influence on outcome, including (A) OSA-related symptoms, (B) cardiometabolic comorbidities, (C) frequency of respiratory events, and (D) age. OSA-related symptoms indicate a strong incitement to treat, whereas the absence of symptoms, age above 65 years, and no or well-controlled comorbidities indicate a weak treatment indication, irrespective of AHI. CONCLUSIONS The novel treatment matrix is based on the effects of treatments rather than the actual frequency of respiratory events during sleep. A nationwide implementation of this matrix is ongoing, and the outcome is monitored in a prospective evaluation by means of the Swedish Sleep Apnea Registry (SESAR).

Abstract
Objectives The aim was to define the characteristics of successful implementation of new clinical endodontic routines within a public dental health organization, following an educational program. Materials and Methods Fifteen staff members were strategically selected for the interview. All had completed a theoretical educational intervention including a complementary endodontic treatment strategy and, for the dentists, comprising training in the nickel‐titanium‐rotary‐technique. All experienced the successful acceptance of new clinical routines. Two thematic in‐depth audiotaped interviews were conducted, wherein the informants described the implementation process in their own words. The interviews were transcribed verbatim and analyzed according to Qualitative Content Analysis. Results A theme was identified: A multiple flexible process with governance support and gradual reinforcement of motivation, with the following main categories: Firstly, contextual facilitation, with two subcategories (i) a multifaceted organizational foundation and (ii) a tolerance of flexibility. Secondly, emotional facilitation, with two subcategories (i) an experience of simplification and (ii) an experience of improvement. Conclusion The results improve the understanding of a multifaceted process underlying the acceptance of changes to clinical endodontic procedures by dentists in a public dental health organization. Important contributing factors identified were governance support, a committed resource person with contextual knowledge, tolerance of flexibility in implementation, and permissive informal communication channels within the local workplace. These findings might be a valuable contribution to an evidence base, facilitating the selection of the most appropriate educational strategy and structure for a specified purpose.

Abstract
Obstructive sleep apnea (OSA) may lead to increased circulating concentrations of inflammatory biomarkers and treatment may change these. We aimed to assess the effect of oral appliance (OA) therapy on inflammatory biomarkers in a randomised controlled pilot trial. A total of 71 patients with OSA and systemic hypertension were randomly allocated to an active, mandible protruded (OAa) or a passive, mandible non‐protruded device (OAp) treatment. Serum concentrations of the inflammatory biomarkers white blood cells, high‐sensitivity C‐reactive protein, interleukin 6, interleukin 10, and tumour necrosis factor‐α were measured at baseline and after 3 months of OA treatment. The differences between treatment groups in biomarker concentration change during the treatment were presented as the Vargha and Delaney effect size and evaluated with the Wilcoxon–Mann–Whitney test. This effect size expresses the probability of a higher value in a random participant from one group compared with a random patient from the other group, and a value of 0.5 means stochastically equal groups. After 3 months of treatment, there was a significant reduction of the apnea–hypopnea index in the OAa group compared with the OAp group (effect size 0.258, 95% confidence interval 0.146–0.386, p < .001). There were no significant differences between the groups in any of the inflammatory markers’ concentration changes during the treatment period (effect sizes between 0.488 and 0.524; all p values ≥.737). Thus, OA treatment for 3 months did not affect circulating concentrations of some common inflammatory markers in patients with OSA and systemic hypertension.

Abstract
Objective: The benefit of bibloc over monobloc appliances in treating obstructive sleep apnoea (OSA) has not been evaluated in randomized trials. We hypothesized that these types of appliances would be equally effective.Material and methods: In this multicentre, randomized equivalence trial, patients with OSA received one type of bibloc or one type of monobloc treatment. At baseline, a 1-night polygraphy study was done, and this was repeated after 1 year. The outcome was any change in the apnoea-hypopnoea index (AHI) and the limits of equivalence between the two devices were set at ±5 AHI units.Results: Of 302 patients, 146 were randomly assigned to bibloc and 156 to monobloc appliances. In 88 and 104 patients, respectively, there were significant reductions in the AHI (p < .001) with a mean change of -16.7 (95% CI -19.4 to -14.1) in the bibloc and -11.8 (-14.9 to -8.7) in the monobloc groups. The proportions of responders defined as having an AHI <10 were 68% and 65% for the bibloc and monobloc groups, respectively. Treatment-related adverse events were mild, transient and the dropouts were more frequent in the bibloc group.Conclusions: Both types of treatments positively and significantly reduced respiratory disturbances, but at the 1-year follow-up, they were not significantly different in treating OSA, with a numerically greater reduction of the AHI value with the bibloc appliance. However, the higher proportion of treatment-related adverse events and higher proportion of dropouts among bibloc users should be balanced against the advantage of a greater reduction in the AHI.

Abstract
Objective: The aim was to study prevalence of xerostomia, hyposalivation and quality of life among caries active younger adults.Materials and methods: A questionnaire regarding oral and general health, xerostomia and quality of life was mailed to 134 caries active (CA) and 40 caries inactive (CI) patients, 25-50 years of age (mean age 39.9 ± 6.2 years) treated at a Swedish Public Dental Service clinic, regarding oral and general health, xerostomia and quality of life. Caries data and unstimulated whole salivary flow rates were obtained from dental records.Results: The overall response rate was 69%. Dental records confirmed that CA patients had more decayed teeth over time than CI patients (p < .001). The CA group reported worse oral health (p < .001) and general health (p < .01), more xerostomia (p < .001) and lower salivary flow rate (p < .01) compared to CI patients. Xerostomia was inversely related to unstimulated whole salivary flow rates as well as to oral and general health (p < .01). There were no differences between groups in quality of life.Conclusion: Younger caries active adult patients reported significantly more xerostomia and hyposalivation compared to caries inactive patients. Xerostomia and hyposalivation were inversely related to perceptions of oral and general health, but not to quality of life.

Abstract
OBJECTIVES The aim of this study was to conduct a cost-effectiveness analysis (CEA) of a high-intensity and a low-intensity smoking cessation treatment programme (HIT and LIT) using long-term follow-up effectiveness data and to validate the cost-effectiveness results based on short-term follow-up. DESIGN AND OUTCOME MEASURES Intervention effectiveness was estimated in a randomised controlled trial as numbers of abstinent participants after 1 and 5-8 years of follow-up. The economic evaluation was performed from a societal perspective using a Markov model by estimating future disease-related costs (in Euro (€) 2018) and health effects (in quality-adjusted life-years (QALYs)). Programmes were explicitly compared in an incremental analysis, and the results were presented as an incremental cost-effectiveness ratio. SETTING The study was conducted in dental clinics in Sweden. PARTICIPANTS 294 smokers aged 19-71 years were included in the study. INTERVENTIONS Behaviour therapy, coaching and pharmacological advice (HIT) was compared with one counselling session introducing a conventional self-help programme (LIT). RESULTS The more costly HIT led to higher number of 6-month continuous abstinent participants after 1 year and higher number of sustained abstinent participants after 5-8 years, which translates into larger societal costs avoided and health gains than LIT. The incremental cost/QALY of HIT compared with LIT amounted to €918 and €3786 using short-term and long-term effectiveness, respectively, which is considered very cost-effective in Sweden. CONCLUSION CEA favours the more costly HIT if decision makers are willing to spend at least €4000/QALY for tobacco cessation treatment.

Abstract
Background The clinical benefit of bibloc over monobloc appliances in treating obstructive sleep apnoea (OSA) has not been evaluated in randomized trials. We hypothesized that the two types of appliances are equally effective in treating OSA. Objective To compare the efficacy of monobloc versus bibloc appliances in a short-term perspective. Patients and methods In this multicentre, randomized, blinded, controlled, parallel-group equivalence trial, patients with OSA were randomly assigned to use either a bibloc or a monobloc appliance. One-night respiratory polygraphy without respiratory support was performed at baseline, and participants were re-examined with the appliance in place at short-term follow-up. The primary outcome was the change in the apnoea–hypopnea index (AHI). An independent person prepared a randomization list and sealed envelopes. Evaluating dentist and the biomedical analysts who evaluated the polygraphy were blinded to the choice of therapy. Results Of 302 patients, 146 were randomly assigned to use the bibloc and 156 the monobloc device; 123 and 139 patients, respectively, were analysed as per protocol. The mean changes in AHI were −13.8 (95% confidence interval −16.1 to −11.5) in the bibloc group and −12.5 (−14.8 to −10.3) in the monobloc group. The difference of −1.3 (−4.5 to 1.9) was significant within the equivalence interval (P = 0.011; the greater of the two P values) and was confirmed by the intention-to-treat analysis (P = 0.001). The adverse events were of mild character and were experienced by similar percentages of patients in both groups (39 and 40 per cent for the bibloc and monobloc group, respectively). Limitations The study shows short-term results with a median time from commencing treatment to the evaluation visit of 56 days and long-term data on efficacy and harm are needed to be fully conclusive. Conclusion In a short-term perspective, both appliances were equivalent in terms of their positive effects for treating OSA and caused adverse events of similar magnitude. Trial registration Registered with ClinicalTrials.gov (#NCT02148510).

Abstract
Background Temporomandibular joint (TMJ) arthralgia is a painful condition assumed to be associated with local inflammation. Objective The objective of the present study was to determine the efficacy for reducing pain of a single‐dose intra‐articular (IA) injection of methylprednisolone to the TMJ. The hypothesis was that methylprednisolone would effectively reduce TMJ pain. Methods This randomised, double‐blind, parallel‐group, multicentre, controlled study included visits for enrolment, treatment and 4‐week follow‐up. The study included patients 18 years and older who had been diagnosed with unilateral TMJ arthralgia. All participants were randomly assigned to receive 1 mL IA injections of methylprednisolone or saline. The primary outcome was change in recorded pain intensity on a visual analogue scale (VAS) at maximum jaw opening, analysed in the per protocol population. Results In total, 54 patients were randomly assigned to single‐dose IA injections with methylprednisolone (n = 27) or saline (n = 27). Between baseline and the 4‐week follow‐up, VAS‐rated pain intensity at maximum jaw opening decreased from a mean of 61.0 (95% confidence interval [CI]: 50.1; 70.7) to 33.9 (95% CI: 21.6; 46.2) in the methylprednisolone group and from 59.6 (95% CI: 50.7; 65.9) to 33.9 (95% CI: 23.8; 43.9) in the saline group. The between‐group difference was not significant (P = 0.812). Treatment‐related adverse events were doubled in the methylprednisolone group. Conclusion Methylprednisolone provided no additional benefit for reducing pain, but caused more harm compared with saline following a single‐dose IA injection in patients with TMJ arthralgia.

Abstract
OBJECTIVES The study aim was to evaluate the prevalence of self-reported temporomandibular disorders (TMD) and acceptance or nonacceptance of such disorders in adult patients attending all public dental health services in the County of Sörmland, Sweden, during a 3-year period, 2011-2013. METHODS Two questions were asked about TMD and the voluntary mouth-opening capacity was measured. The results were registered in a score 0-3. The registration was completed with a question about each patient's acceptance or nonacceptance of their condition. RESULTS More than 73,000 registrations of the TMD condition were performed in general dental clinics from 2011 to 2013. The mean prevalence of a TMD score of 1-3 was 5% and was consistent over these years. Seventy percent of these patients were women. The peak prevalence of TMD was registered in patients aged 30-45 years (38%), and the frequency declined in older age groups. Reduced voluntary mouth-opening capacity (≤35 mm) was found in less than 2% of the participants. About one-fifth of the patients with a TMD-score of 1-3 did not accept their condition and wanted professional care. The frequency of nonacceptance of the condition increased with the severity of symptom score: 15%, 27%, and 49% for scores 1, 2, and 3, respectively. CONCLUSIONS This study shows that the prevalence of self-reported TMD in adult patients was consistent from 2011 to 2013 and should be considered as a public health issue in Sweden. Patients with more severe TMD pain symptoms wanted care more frequent. The annual clinical calibrations should be continued to achieve an acceptable level of registration.

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.

Abstract
OBJECTIVE The aim of the study was to investigate the self-perceived level of knowledge, attitudes and clinical experience in treatment of temporomandibular disorders (TMD) among general practising dentists (GPDs). MATERIAL AND METHODS A web-based questionnaire was sent to all GPDs in the public dental health service in the County of Uppsala in 2010 (n = 128) and 2014 (n = 113). The GPDs were asked to answer questions in the following categories: Demographic information, Quality assurance, Clinical experience and treatment, Need for specialist resources in the field of TMD and Attitudes. Between the two questionnaires, the GPDs were offered TMD education and an examination template including three TMD questions was introduced in the computer case files. The results were also compared with a previous questionnaire from 2001. RESULTS The response rate was 71% (2010) and 73% (2014). The majority of the GPDs were women (70% in 2010 and 72% in 2014). The reported frequency of taking a case history of facial pain and headache increased between 2010 and 2014. In 2014, the GPDs were more secure and reported higher frequency of good clinical routines in treatment with jaw exercises and pharmacological intervention compared to 2001. Interocclusal appliance was the treatment with which most dentists felt confident and reported good clinical routines. CONCLUSIONS The GPDs felt more insecure concerning TMD diagnostics, therapy decisions and treatment in children/adolescents compared to adults. There is a high need for orofacial pain/TMD specialists and a majority of the GPDs wants the specialists to offer continuing education in TMD.

Abstract
Over the past few decades, there has been a pronounced increase in the number of patients being treated by general dental practitioners for obstructive sleep apnoea (OSA). The purpose of this study was to survey the care and patient experiences and the self-reported effectiveness of OSA treatment with an oral appliance (OA) incorporating mandibular advancement. The design was a retrospective, cross-sectional study, with follow-up between 6 months to 1 year after commencement of treatment. A survey form was posted to 1150 subjects, identified in the regional register over a 1-year period as having been treated with an OA for OSA. The questionnaire comprised 70 questions and assertions in various domains, such as general health/lifestyle, changes in symptoms/quality of life and sleep-related experiences, daytime sleepiness, changes in life situation, evaluation of treatment and the value of treatment. The overall response rate was 64% (n = 738). Treatment with OA gave relief of symptoms in 83% of the respondents. Quality of life, somatic and cognitive symptoms improved significantly in patients who used the appliance frequently (P < 0·001). Daytime sleepiness decreased significantly (P < 0·001). Treatment satisfaction and willingness to recommend the similar treatment to a friend were high (>85%). OA treatment of OSA by general dental practitioners is a safe procedure. Most of the survey respondents experienced relief of symptoms. Those who used their appliance frequently reported improvement in quality of life, somatic and cognitive symptoms. Excessive daytime sleepiness was reduced in the majority of the patients under treatment.

Abstract
The aim of this study was to measure patient-reported outcomes of caries prophylaxis and to compare them with previously documented efforts in dental offices. 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 overall response rate was 69%. The questionnaire included items regarding patient perceived caries prophylaxis in relation to: 1) treatment and recommendations given by the dental personnel, 2) performed self-care and 3) perceived and expected effects.The responses were studied for their association to clinical data, extracted retrospectively from the patients' dental records.The mean follow up time was > 16 years. Information about caries prophylaxis (p = 0.01) and recommendations for self-care (p = 0.04) were given more often to the CA group than to the CI group. Supplementary examinations and recommendations of self-care risk treatments were more frequent in the CA group (p < 0.001). CA patients also made more frequent extra efforts at home to avoid caries by changing their eating habits (p < 0.001), improving their oral hygiene (p = 0.04) and using extra fluoride (p = 0.001). In the CA group, 60% did not considerthat the extra prophylaxis efforts had made them caries inactive, and 40% were not satisfied with the outcome. Most patients (> 90%) hoped that the outcome of caries prophylactics would be a reduced number of cavities.The patient-perceived experiences of caries prophylaxis-were in concordance with dental records. Both the dentists and the caries active middle-aged Swedish adults were aware of the need for extra prophylaxis.The caries active patients perceived having made extra home care efforts, but had not experienced that they had become free from caries.

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.

Abstract
AIM To compare the technical quality and long-term outcomes of root canal treatment by general practitioners of a Swedish Public Dental Service, before and after an endodontic education including Ni-Ti rotary technique (NiTiR). METHODOLOGY A random sample was compiled, comprising one root filled tooth from each of 830 patients, treated by 69 general practitioners participating in the education: 414 teeth root filled in 2002, pre-education, using primarily stainless steel instrumentation and filling by lateral compaction, and 416 teeth root filled post-education (2005), using mainly NiTiR and single-cone obturation. Follow-up radiographs taken in 2009 were evaluated alongside immediate post-filling radiographs from 2002 to 2005. The density and length of the root fillings were registered. Periapical status was assessed by the Periapical Index (PAI), using two definitions of disease: apical periodontitis (AP) (PAI 3 + 4 + 5) and definite AP (PAI 4 + 5). Tooth survival was registered. Root fillings pre- and post-education were compared using chi-square and Fisher's exact tests. Crude extraction rates per 100 years were calculated for comparison of tooth survival. Explanatory variables (type of tooth, root filling quality, periapical status, marginal bone loss, type and quality of coronal restoration) in relation to the dependent variable (AP at follow-up) were analysed by multivariable logistic regression. RESULTS Follow-up data were available for 229 (55%) of teeth treated pre- and 288 (69%) treated post-education: both tooth survival (P < 0.001) and root filling quality were significantly higher (P < 0.001) in the latter. However, there was no corresponding improvement in periapical status. Both pre- and post-education, root fillings with definite AP on completion of treatment had significantly higher odds of AP or definite AP at follow-up. For teeth treated post-education, inadequate root filling quality was significantly associated with AP at follow-up. CONCLUSIONS Despite a higher tooth survival rate and a significant improvement in technical quality of root fillings after the education, there was no corresponding improvement in periapical status.

Abstract
PURPOSE The purpose of this study was to evaluate patient safety, in terms of adverse events, alterations in blood pressure or oxygen saturation (SpO2) in two routine sedation procedures, with and without intravenous analgesia. METHODS Patients referred for surgical removal of mandibular third molars were treated in a randomized, controlled, single-blinded procedure. Eighty-seven men and women, aged 18 to 44 years, were allotted to either of two treatment groups, midazolam + tramadol (M + T) and midazolam + saline (M + S) or to a control group (C), given no sedation. RESULTS Tramadol at 1 mg/kg body weight resulted in a higher frequency of oxygen desaturation (SpO2 < 90 %) than a placebo (p = 0.002) but had no effect on mean SpO2 at the end point or at the end of surgery. In both the test groups, there was a significant decrease in diastolic blood pressure (p < 0.001) from baseline to the end of surgery. CONCLUSION The results confirm that pre-emptive intravenous tramadol, administered at 1 mg/kg body weight as an adjunct to midazolam sedation for third molar surgery, offers a safe method. But, it should be noted that our previous study shows that it is not a particularly effective analgesic. Further testing is therefore warranted, using other doses or other drugs, to find a better intravenous protocol for postoperative analgesia, with maximum effect and minimal risk, in outpatient oral and maxillofacial surgery procedures.

Abstract
OBJECTIVE To analyse the prevalence of temporomandibular disorders and related pain (TMD-pain) among adult recall patients in general dental practice. MATERIALS AND METHODS From November 2006 to September 2008, all adults attending a Swedish Public Dental Service (PDS) clinic for recall examination were asked two standardized questions about temporomandibular pain and dysfunction. Mouth-opening capacity was measured. The responses to the questions and mouth-opening capacity were combined to give a TMD-pain score, on a scale of 0-3. The patients' acceptance of their TMD condition was also noted. RESULTS The subjects comprised 2837 adults (53% females, 47% men). Of the total sample, 4.9% reported a TMD-pain score of 1-3. The gender difference was significant: women predominated (p < 0.003). Forty-three per cent of those with TMD-pain scores of 1-3 (36% men, 47% women) considered that the condition warranted treatment, especially those registering a pain score (significant difference between pain and dysfunction groups, p < 0.000). CONCLUSIONS The TMD-pain score shows promise as a useful instrument for detecting and recording TMD-pain. The prevalence of TMD disclosed in the study is high enough to be considered a public health concern. Most of the subjects with lower scores on the TMD-pain scale accepted their condition as not severe enough to require treatment.

Abstract
The aim of this study was to explicate and describe the qualitative meaning of successful clinical and organizational change in endodontic practice, following a comprehensive implementation program, including the integration of the nickel-titanium-rotary-technique. After an educational intervention in the Public Dental Service in a Swedish county, thematic in-depth interviews were conducted, with special reference to the participants' experience of the successful change. Interviews with four participants, were purposively selected on the basis of occupation (dentist, dental assistant, receptionist, clinical manager), for a phenomenological human scientific analysis. Four constituents were identified as necessary for the invariant, general structure of the phenomenon: 1) disclosed motivation, 2) allowance for individual learning processes, 3) continuous professional collaboration, and 4) a facilitating educator. The perceived requirements for achieving successful clinical and organizational change in endodontic practice were clinical relevance, an atmosphere which facilitated discussion and allowance for individual learning patterns. The qualities required in the educator were acknowledged competence with respect to scientific knowledge and clinical expertise, as well as familiarity with conditions at the dental clinics. The results indicate a complex interelationship among various aspects of the successful change process.

Abstract
Background Achieving lifelong tobacco abstinence is an important public health goal. Most studies use 1-year follow-ups, but little is known about how good these are as proxies for long-term and life-long abstinence. Also, intervention intensity is an important issue for development of efficient and cost-effective cessation treatment protocols. The study aims were to assess the long-term effectiveness of a high- and a low-intensity treatment (HIT and LIT) for smoking cessation and to analyze to what extent 12-month abstinence predicted long-term abstinence. Methods 300 smokers attending dental or general health care were randomly assigned to HIT or LIT at the public dental clinic. Main outcome measures were self-reported point prevalence, continuous abstinence (≥6 months), and sustained abstinence. The study was a follow-up after 5–8 years of a previously performed 12-month follow-up, both by postal questionnaires. Results Response rate was 85% (n=241) of those still alive and living in Sweden. Abstinence rates were 8% higher in both programs at the long-term than at the 12-month follow-up. The difference of 7% between HIT and LIT had not change, being 31% vs. 24% for point prevalence and 26% vs. 19% for 6-month continuous abstinence, respectively. Significantly more participants in HIT (12%) than in LIT (5%) had been sustained abstinent (p=0.03). Logistic regression analyses showed that abstinence at 12-month follow-up was a strong predictor for abstinence at long-term follow-up. Conclusions Abstinence at 12-month follow-up is a good predictor for long-term abstinence. The difference in outcome between HIT and LIT for smoking cessation remains at least 5–8 years after the intervention. Trial registration number NCT00670514

Abstract
The aim of this study was to determine the analgesic efficacy of a single dose intra-articular injection (i.a.) of morphine in 53 patients with unilateral arthralgia/osteoarthritis of the temporomandibular joint (TMJ). This randomized, double-blind, parallel group, multicenter study included a screening visit, a treatment visit, and a follow-up visit 1 week after treatment. Recordings of visual analog scales (VAS) pain intensity scores at maximum mouth opening (main efficacy variable) and at jaw rest were made directly before a 1-ml i.a. injection into one TMJ of either 1.0mg morphine-HCl, 0.1mg morphine-HCl, or saline (placebo). The pain intensity was also recorded at the follow-up and in a diary 3 days before and 5 days after the injection. The VAS pain score at maximum mouth opening was considerably reduced 1-10h after injection but without significant differences between groups. At the follow-up, the median VAS pain score at maximal mouth opening was significantly lower in the 0.1-mg morphine group than in the 1.0-mg morphine group (P<0.043) or the saline group (P<0.021). A significant increase in pain pressure threshold over the affected joint was seen in the 0.1-mg morphine group compared with the saline group at the follow-up but not 1 and 2h post-injection. The incidence of adverse events was small and did not differ between the treatment groups. In conclusion, one i.a. injection of 0.1mg morphine significantly increased the pain pressure threshold and mouth opening ability, but evidence for the analgesic property of the locally applied opioid was inconclusive. No dose-effect relation and no significant short-term analgesic property were seen. Although statistically significant, the magnitude of the reduced VAS pain intensity score was not clinically relevant at the 1-week follow-up.
