The aim of this retrospective study was to evaluate the clinical survival and success of five dif- ferent types of adhesive bonded all-ceramic restorations, in a postgraduate clinic. All ceramic enamel-dentin adhesive bonded restorations, either partial (n=94) or full coverage (n=145), were assessed by clinical examination using a modified Californian Dental Association (CDA) system for quality evaluation of dental care and a questionnaire assessing patient satis- faction (VAS) of 29 subjects with 239 restorations. The same 3-step adhesive bonding system in combination with dual-cured resin composite cement was used for all restorations Rubber dam was used for moisture control.The ceramics were evaluated with respect to patient satisfaction, esthetics, technical and biological complications. The reasons for treatment were mineralisation disorders (n=82), trauma (n=40), esthetic (n=57) and pathological tooth wear (n=60). Observation period for the restorations was up to 71 month (mean 33). All restorations were in place at the examinations (l00% survival rate). Number offractures and infractions were 28 and 20 respectively giving a 69% success rate. No significant difference was observed between full coverage and partial coverage restorations. Most of the fractures were small chippings of the veneering porcelain. From a biological point of view subgingival location of the restoration margin showed a significant correlation with bleeding on probing.The esthetic outcome seemed to depend on the ability of the selected veneering material to mask a severe tooth discoloration.The patients reported a high degree of satisfaction with both the esthetics and the function of their restorations. In conclusion all-ceramic enamel-dentin-bonded restorations demonstrated good short-term survival rate.The success rate was found to be lower. Both technical and biological complica- tions were present but mainly without any need of correction.The patients were in general very satisfied with the result of their dental treatment both esthetically and functionally.

For decades, Swedish dental professionals have collected clinical epidemiological data from the dental records. To supplement the epidemiology, Ostergötland County Council decided to examine patient perceptions of oral health: self-rated knowledge, self-perceived oral health, and opinions about oral health. The aim was to compare self-perceived oral health among 19-year-olds to determine differences between genders, various municipalities and between 2004 and 2011. This study analysed the responses from two cross-sectional surveys of the entire population of 19-year-olds in Ostergötland County, Sweden, performed in 2004 and 2011. Of the 2,413 (53%) (50% men, 50% women) 19-year-olds who responded to the questionnaire in 2004 and the 3,803 (67%) (50% men, 50% women) in 2011, most 19-year-olds (88.1% [2004] and 87.5 % [2011]) reported satisfaction with their oral health. Around half of the respondents rated their knowledge on periodontitis as low. Boys rated their knowledge about avoiding periodontitis higher than girls (p < 0.05 in 2004 and p < 0.001 in 2011). In 2004, 84.7% reported shooting pain. In 2011 that figure was 83.7%.The respondents expressed some uncertainty about the benefits of fluoride toothpaste (7.5% in 2004 and 9.3% in 2011), especially the boys (10.3% in 2004 and 10.5% in 2011). Girls reported both a higher social impact and greater concern about aesthetics related to their oral health. They also reported headache (27.5%) nearly twice as often as boys (14.2%) (p > 0.001). Responses between the municipalities did not differ, with the exception of items regarding periodontitis. Thus, this study found indications that perceptions of oral health and knowledge in Ostergötland County complied with Swedish Dental Act. The study also found patient perceptions of oral health among 19-year-olds to be good.

The aims of this study were to evaluate treatment outcome with activator-headgear combinations carried out by general dental practitioners, overall costs, long-term stability and patients' satisfaction with treatment outcome. Patients who were recommended to start treatment in 2006 were included in this study (n = 97). Inclusion criteria were: Class II Division 1 with at least half a cusp width distal molar relationship, overjet ≥ 6 mm and presence of dental records. Data were collected, pre-treatment, post-treatment and 3 years after treatment for those with favorable outcome. Patients at follow-up completed a questionnaire about satisfaction with treatment outcome, perceived pain and discomfort during treatment, and subjective need for additional treatment. Eighty-five patients were analyzed, 52 boys and 33 girls (mean age 11.2 years SD 1.39). Thirty-five patients had successful treatment outcome, 15 partially successful and 35 had an unsuccessful outcome. Total costs for all 85 patients amounted to SEK 1 405 000 including both direct and indirect costs. Thirty-eight patients participated in the 3-year follow-up. Treatment outcomes were then categorized as successful in 28 patients, partially successful in 9 patients and 1 patient was judged as unsuccessful. Median values on VAS (0-100) for overall satisfaction with treatment and treatment outcome were high, 78 and 84 respectively. Median value for perceived pain and discomfort during treatment was 42. Just over half of the patients had a favorable treatment outcome. Patients with favorable outcome were stable over time and satisfied with treatment.

The aim of the study was to evaluate the technical quality of endodontic treatment per- formed by postgraduate students in Karolinska Institutet, Stockholm, Sweden during the years (2008-2011) and to evaluate the treatment outcome. In addition, possible influencing factors to treatment outcome were analyzed. All maxillary first molars that received endo- dontic treatment between 2008 and 2011 were included in the study. Pre, post and follow up radiographs were collected.The apical status (PAI-score),the quality of the root canal treat- ment (RCT) and the treatment outcome were assessed. Analysis of the treatment outcome in relation to the quality of root canal treatment and other possible influencing variables was performed by Chi2 or Fisher's Exact test, and the statistical significance was set at P<0.05. A total of 73 teeth were included in the study. Out of these, sixty-three teeth (86,3 %) had periapical lesions at the time for RCT. An initial root canal treatment was performed in 46 teeth (63 %) and 27 teeth (37 %) were retreated.There was no significant as- sociation between the outcome and the type of treatment.The majority of the RCT's (58 %) had good seal and correct length. In total, the treatment outcome was successful in 59 (81 %) of the cases. The success rate was 88% in cases with high quality root fillings, compared to 71% in cases with less good quality.There was a non- significant trend (P =0.066) of an association between RCT quality and treatment outcome. In conclusion the association between the quality of the root filling and the treatment outcome was not verified with statistical significance, but the results indicate a trend that satisfactory root fillings are associated with a favorable outcome.This study was limited by its retrospective nature and a relatively small sample size.

Aim of the study was to determine the effect of an alcohol-free chlorhexidine mouth rinse and an essential oils containing mouth rinse on pro-inflammatory cytokine levels in gingival crevicularfluid in participants who continue to perform their regular mechanical oral hygiene regimes and normal dietary practice. Twenty adult volunteers (mean age: 59 years) participated in the double-blind randomised controlled cross-over study.Three mouth rinses were used during 16-day periods as an adjunctiveto regular mechanical oral hygiene: a solution with alcohol-free chlorhexidine (CHX; Paroex), a solution with essential oils (EO; Listerine), and water (negative control).The mouth rinse periods were separated by 3-month washout periods. At days o (baseline) and 17 (end) of each mouth rinse period, gingival crevicular fluid (GCF) was collected at different tooth sites and analyzed with ELISA technique for IL-1α, IL-1β and IL-ira levels. No significant correlations between clinical parameters (QHI and GI) and cytokine concentra- tions were observed, regardless of mouth rinse regimen.The generalized linear models revealed that none of the mouth rinses had a statistically significant impact on IL-1 concentrations in GCF. Large inter-individual variations were observed for the levels of IL-iα, IL-1β and IL-ira. Also the changes in concentrations between day o and day 17fo r the mouthrinses showed large intra-individual variations. It can be concluded that neither the alcohol-free chlorhexidine nor the mouth rinse contain- ing essential oils reduced the levels of IL-iα, IL1β and IL-ira in GCF.

The aim was to study the cognizance of and attitudes towards the Shortened Dental Arch (SDA) concept among Swedish General Dental Practitioners (GDPs) and the application of the SDA concept in their treatment planning using Qualitative Content Analysis. Eleven Swedish GDPs were purposively selected and all agreed to participate. In-depth semi-structured interviews were conducted and covered treatment considerations concerning two patient cases and the participants' reflections regarding pre-formulated statements about the SDA concept. Qualitative content analysis was used to analyze this data.The emerging theme was "the SDA concept is irrelevant" in the sense of the GDPs disregarding treatments providing dentitions with loss of posterior teeth. There was a strong reluctance to extract teeth, without consideration of the SDA concept, and a firmly patient-focused attitude towards the needs, age and financial situation of the patients. Within the limitations of this study, Swedish GDPs show little or no cognizance of the SDA concept and it does not seem to be applied in their treatment planning. The results show that the qualitative methodology can be beneficial for further understanding of cognizance and attitudes towards the SDA concept.

Objectives: To investigate the outcome of vital root resection followed by immediate pulp capping with MTA in furcation involved maxillary molars.

Material and methods: This pilot clinical study of 12 months duration was designed to evaluate the outcome of vital root resection in maxillary molars with degree II furcation involvement combined with conservative endodontic treatment by means of pulp capping with mineral trioxide aggregate (MTA). Seven teeth in six adult patients suffering from adult chronic periodontitis were included in this study.

Results: At the final 12 month examination interval, one tooth had received root canal therapy subsequent to the 6-month evaluation. The remaining six teeth remained clinically vital for the duration of the study and required no further treatment at 12 months.

Conclusion: Results of this study provide limited data that can be used in a further investigation with similar methodology and a sufficient sample size in a randomized clinical trial model.

Miniscrew implants (MSI) can be a useful tool when maximal anchorage is desired in ortho- dontic treatment.The aim of this study was to describe the opinions and experiences of mini- screw implants among orthodontists currently practising in Sweden. A web-based anonymous questionnaire containing 17 multiple choice questions was sent to 218 listed members of the Swedish Association of Orthodontists during fall 2012. Descriptive statistics were used for analysing the collected data set. In a total of 147 (67%) respondents 80 were women, 62 were men and five did not specify gender. MSI had been used by 78 (53%) respondents in orthodontic treatment.The majority of the respondents, 53 (70%), had used i-io MSI.The majority of MSI placements were made by orthodontists (84%) while 18 (9%) referred the procedure to an oral surgeon. The most common indications for MSI were space closure, intrusion, and bodily movements. The use of MSI enabled 61 (81%) of the respondents to set higher treatment objectives.The suc- cess frequency of the MSI was perceived as satisfactory by 48 (65%) of the respondents.

In general, most infectious and/or lifestyle-related diseases are defined as being present when sufficient signs or symptoms occurs in an individual. The term "sufficient".is a relative concept and a disease can therefore be measured with different degrees of certainty.These symptoms are commonly defined in such a way that it is possible to determine the incidence and prevalence of the disease and also the proportion of individuals that are cured from the dis- ease. If dental caries is an individual disease which can be compared to other diseases regarding incidence and prevalence, it is important to determine for how long an individual must be free from new signs of the disease before being considered cured or free from the disease and to define the "sufficient" signs or symptoms needed for a diagnose. Based on these thoughts, the purpose of this study was to calculate caries incidence and prevalence in a group of adolescents from a definition of dental caries based on ICD-1o. This study included all12 year olds in 1990 who attended a clinical dental examination in 1990-1995 in Orebro County, Orebro, Sweden, yearly during these six years. Dental caries disease at the individual level was defined as K02.1 (dentinal caries) according to ICD-io while freedom of caries was defined as the absence of K02.1 during a three-year period. In this study the yearly prevalence was 12%, the three year cu- mulative incidence was 18% and the incidence rate 13%. Results of this study highlight the poor outcomes in curing caries disease in this age-group, according to the criteria in this study, as only 17% of the children with caries at the outset of the study were free from the disease three years later. Defining both a practical level to measure signs of dental caries, and the period an individual must be free from them to be classified as cured from the disease create new oppor- tunities to compare and communicate the disease of dental caries with other diseases.This way of registration is also of advantage for planning purposes as there the centre of interest must be the individual patient and not the tooth or surface.
