Abstract: Introduction: The importance of good oral health in children is well documented. Extensive caries in young children has an impact on both oral and general health, including quality of life. It is important to offer DGA for patients where other options are not sufficient. Preventive measures can in many cases be done to reduce the number of DGA needed, and behaviour shaping techniques for all children will in the long run be cost effective. In Tromsø DGA is performed by two paedodontists. Objective: Investigate patient experiences with dental treatment under GA in Tromsø, with emphasis on preventive measures previous to DGA, information received and patient follow-up. If necessary promote suggestions for improvement. Method and materials: Telephone interviews with the parents of ten children that had received DGA at UNN Tromsø. Conclusion: Most parents were content with overall DGA experience and found the waiting time from referral to treatment acceptble. In most cases, other measures had been tried before DGA. Some improvements could be done regarding parent information. URI: http://hdl.handle.net/10037/4249 File(s) in this item: 1

Abstract: Introduction: The aim of this study was to find the prevalence of oral mucosal lesions in the adult and child populations, examined or treated at external university dental clinics of the University of Tromsø, and then compare these prevalences with prevalences found in previous studies. Methods: A questionnaire was sent to the external University dental clinics (n=14), inviting all dental practitioners and hygienists to participate. During eight weeks the examiners reported all the oral mucosal lesions found during examination or treatment of their patients. Results: Twelve out of 14 clinics participated in the study (86%), and a total of 8088 (3122 adults and 4966 children) patients were examined by 39 examiners. Oral mucosal lesions were found in 7.59% of adult patients and in 2.68% of patients under the age of 18. The prevalence’s of oral mucosal lesions were generally lower compared to previous studies. Conclusion: Some of our results may indicate underregistration of oral mucosal lesions compared to previous studies. However, the previous studies have been conducted in other countries, and may not produce valid estimators of prevalences in Norway. To find the prevalence of oral mucosal lesions in Norway, a study on a general population that is stratified and randomly selected should be carried out.

Abstract: Abstract: Objective: The aim was to describe the different bone enhancing techniques for improving the alveolar bone and gingival characteristics prior to implant placement Material and methods: A MEDLINE and PubMed English language peer-reviewed literature search was conducted. Hand searches of the reference lists in some selected articles were also conducted. The literature search was sorted into five different topics; autogenous bone graft, guided tissue regeneration, orthodontic extrusion, and distraction osteogenesis. Results: Forty-seven articles were considered for the review. All, except one, of the selected articles were case reports or case series describing the bone-modifying techniques. Significant improvements in alveolar bone were reported in all cases, resulting in satisfying implant sites. Conclusions: For all five techniques presented there is a need for more research and more precise procedure protocols. Key words: Implant site development, anterior maxilla, autogenous bone graft, guided tissue regeneration, decoronation, orthodontic extrusion, distraction osteogenesis URI: http://hdl.handle.net/10037/4250 File(s) in this item: 1

Abstract: Introduction: The Public Dental Service in Norway has changed during the last decades. Dental hygienists have increased in numbers, but how this has influenced the organization of the patient treatment at the clinics is not well known. Aim: The aim of this study was to investigate the organization of the work-day in the Public Dental Service in Northern Norway in terms of who is being treated and what treatment is being performed. The aim was also to explore how the patients are distributed between dentists and dental hygienists. Method: A self-report questionnaire was sent to dentists and dental hygienists at three different clinics in each of the three northern counties of Norway. Interviews with some of the clinic managers of the participating clinics were also performed. Results: Time spent on each patient was relatively high. Dentists provided mostly reparative treatments on adult population, but with some variation in treatment provided in different counties. Dental hygienists did more preventive treatments on children (aged 0-18). Conclusions: Treatments performed across the three counties were relatively similar. Dentists mainly provide restorative treatments, dominated by dental fillings. Dental hygienists mainly provided examinations and preventive treatments, with the majority of patients being children. Through the study, it clearly appears that patients of age 18 or below dominate the Public Dental Service. This study shows a need for further studies to reveal what future challenges the Public Dental Service is facing in terms of models of organization and delegation of treatments.

Abstract: You can often hear people within the dental care system in Norway expressing that: “if you take a job in Finnmark you will get to do a lot and gain a lot of experience”. This claim might be based on the fact that there are very few specialists in Finnmark. In addition, low population density with long distances to dental service creates a high degree of independence and self-reliance among dental health personnel in the area. This combined with higher frequency of irregular treatment habits among adults and inferior oral health conditions compared to the rest of the country (St.meld 35) might yield an extra challenge to dentists, particularly in more remote areas of Finnmark.

Abstract: Det finnes ulike oppfatninger angående ortodontisk behandling av tenner som er tidligere rotfylt eller tidligere traumatisert. Noen mener at det finnes mer risiko for resorpsjon ved ortodontisk forflytning av slike tenner enn levende "friske" tenner. Det første målet med dette litteraturstudiet var å se om det finnes vitenskapelige bevis for eventuell risiko for resorpsjon ved ortodontisk forflytning av rotfylte/tidligere traumatiserte tenner. Det andre målet var å finne ut hva praktiserende tannleger mener om temaet. 23 artikler var samlet inn gjennom PubMed og veiledere, samt 6 bøker var valgt fra det Helse- og Naturvitenskapelige Biblioteket ved UiT. Et spørreskjema med påstander ang ortodontisk forflytning av rotfylte tenner og tidligere traumatiserte tenner var delt ut til tannleger/spesialister på Studentklinikken og TkNN. Antall spørreskjema utdelt var 41,og 21 var besvart. Resultatene fra litteraturen var at rotfylte tenner (hvis godt renset og tettet) kan forflyttes med samme sikkerhet som vitale tenner. Når det gjelder tenner med tidligere historie av trauma, så sa mesteparten av litteraturen at det er noe større risiko for resorpsjon ved ortodontisk behandling av slike tenner. Besvarelsene av spørreskjema viste at meningen er delt (50/50) ang mer risiko for resorpsjon av rotfylte tenner. Derimot var de fleste deltakere (95%) enige om at det er mer risikabelt å forflytte tenner med tidligere trauma enn tenner uten trauma. Hovedkonklusjonen er at på grunn av lite tilgjengelige artikler og ingen RCT-studier (randomiserte kontrollerte studier) angående tema diskutert i denne masteroppgaven, trengs det mer forskning for å gjøre opp en sikker mening. Større antall deltakere i spørreundersøkelsen er også ønskelig for å føre resultatene over på allmenheten av praktiserende tannleger i Norge.

Abstract: ABSTRACT: Introduction: Some bleaching modalities include an activation process with the utilization of heat or light to enhance the effect of bleaching gel. Aim: To compare the effect of treatment and the contentment among patients having received bleaching therapy with two different approaches. Methods and Materials: Six men and six women ranging from 22 to 61 years of age were included and divided into two groups. Opalescence 10% carbamide peroxide-gel was administrated in individual bleaching trays in Group I for two hours a day for fourteen days and in Group II for two hours a day for fourteen days and 2x1 hour in-office tooth whitening sessions. In Group II, the same bleaching agent and tray was used plus a light activation with an LED-lamp for forty seconds per tooth being treated. Results: Eleven patients completed the study. Group I had an average colour change of –5,36 steps on a modified VITA-scale and Group II –4,30. The patients in Group II seemed to be more satisfied with the treatment outcome compared to the subjects in Group I. Conclusion: Only speculations regarding the outcome of the study can be made. However, it appears as if patients receiving a more advanced bleaching therapy including the use of light become more satisfied with the end result compared to patients receiving at-home based whitening only. This seems to be the case even if patients given at-home bleaching therapy achieve an objectively better end result of the treatment. URI: http://hdl.handle.net/10037/4211 File(s) in this item: 7

Abstract: Objective: To understand the dental health challenges of recovered drug addicts, and how the system of oral health rehabilitation works and functions as seen from the perspective of recovered addicts. Basic Design: Semi-structured interviews with seven recovered drug addicts from the city of Tromsø, Norway. The audio from the interviews was transcribed and analysed using NVIVO software. Results: All informants had experienced or were experiencing oral health problems related to their history of drug abuse. These problems adversely affect their quality of life. The care-seeking process was perceived as challenging by some informants; both in the case of obtaining emergency treatment when they were active addicts, and in relation to full oral health rehabilitation when enrolled in drug rehabilitation programs. Also, some groups of addicts were found to be left out of the legislative framework of the system. Conclusion: The system of oral health rehabilitation for recovered drug addicts has undergone legislative changes over the later years. This seems to have made the system somewhat more effective and including, but there are still groups left outside the system that, it could be argued, should be included. Also, challenges exist in conveying to drug addicts the possibilities for financial aid for emergency treatment. URI: http://hdl.handle.net/10037/4198 File(s) in this item: 1

Abstract: Objective: The purpose of this study was to find out how screening and referring arrangements of patients with malocclusions was working between different dental professional groups in the public dental health services in Troms County. We also wanted to find out to what extent general dentists in Troms County were involved in interceptive orthodontic treatment. Material and Methods: The study subjects were dental hygienists, dentists and orthodontists in Troms County. All dentists and dental hygienists working in the dental public health care in Troms County were invited to participate in the survey. After several reminders 18 dental hygienists, 39 general dentists and 6 orthodontists responded (total N=63). The data was collected through a questionnaire, which included questions on personal data, orthodontic screening, treatment and referring, and a clinical photo of a unilateral posterior crossbite. Results: The response rate was 64%. The most common age of referring children to orthodontic treatment was at 12-13 years of age. Late referral age (14 years or older) was significantly more often favored by dentists, as compared to the dental hygienists. 71% of dental hygienists preferred referring patients straight to a specialist, and the rest made the decision between dentist and specialist. There was no significant difference (P=0,741) in the approximated number of referrals made by the dentists and dental hygienists. 62% of the dentists and 44% of the hygienists considered that treatment of unilateral posterior crossbite belonged to both dentists and specialists. Almost one third of the dentists reported that they did no orthodontic treatment at all. The most common malocclusion treated by the dentists was unilateral posterior crossbite. The procedures related to orthodontics done by dentists in their daily practice, were screening for malocclusion, preventive palpation of the position of permanent canines and primary tooth extractions due to orthodontic reasons. 83% of the orthodontists consulted dentists regarding interceptive orthodontic treatments and/or planning treatments of patients. Conclusions: The majority of dentists in Troms County were involved in orthodontic treatment, but only to a small extent. Dental hygienists and dentists referred approximately the same number of patients to orthodontic treatment, but general dentists may prioritize later age of referral. Availability of continuing education in orthodontics might enhance the treatment skills and interest in orthodontics among the general practitioners.

Abstract: Several factors will have effect dental restorative materials in the oral environment that can affect the longevity of the material. Today dental composite resin-based materials (CRM) used to a major extent. The monomer mixture is of importance in CRMs and efforts are made to improve the materials by changing the monomer content. The present study investigated the effect of an increasing amount of Ethoxylated Bisphenol-A-Dimethacrylate (Bis-EMA) in experimental composite resin-based materials for dental use on the sorption and solubility behavior. Four different polymer mixtures containing Urethane dimethacrylate (UEDMA), Triethyleneglycol dimethacrylate (TEGDMA), Bis-glycidyl-dimethacrylate (Bis-GMA) Bis-EMA were used. The amount of UEDMA and TEGDMA were stable, while the content of Bis-EMA and Bis-GMA varied. For each group, 6 samples of each material were made for the 3 different storage periods (24 H, 7 and 30 days). The procedure was made according to ISO standard (4049:2009). Water sorption and solubility were calculated and statistically analyzed using ANOVA test and Tukey as post hoc (p<0.05). The results showed that water sorption increases with increasing content of Bis-GMA and decreasing content of Bis-EMA. The material containing less Bis-EMA, showed the lowest weight gain after the drying period. That may have a clinical effect on the degradation of the material.

Abstract: Diagnosis and treatment of the caries disease and post-treatment follow-up are interconnected concepts. The aim of the study was to map out the diagnostic methods available for early caries lesions, the existing non-invasive caries treatment, and in what way the follow-ups of these treatments are conducted. The selection of articles was based on a primary search using the PubMed search engine, including search words associated with the topic. The papers which the primary search yielded were put through several exclusion rounds to limit the number and heighten the relevance of the studies to be included. 13 studies were ultimately chosen: 10 clinical studies, 2 systematic reviews and 1 literature review. The results showed that most of the major diagnostics methods used today, when combined, have high sensitivity and specificity for identifying dentin caries. However, they do not have as high specificity and sensitivity for identifying enamel caries. The treatment modalities examined in this study showed promising results, but most of the treatments investigated are in need of more (gap filling) research and long-term follow-ups. The visual tactile method is still the clinician’s most valuable diagnostic tool for identifying caries in general. URI: http://hdl.handle.net/10037/4229 File(s) in this item: 1

Abstract: Introduction: Dentists give dental treatment with resin-based materials to patients every day, and these materials are known to contain several substances that may cause unwanted reactions in human. Possible reactions in a shorter time limit are contact allergy and toxic contact dermatitis. Some plastic materials are also known to release substances which may have an estrogenic effect. Aim: The aim of this master thesis was to explore by a literature research the risk for the patient getting adverse reactions when treated with resin-based materials. Materials and Methods: Relevant studies were acquired through a search in PubMed for adverse reactions and resin-based materials. Three relevant articles were found. Results and Discussion: Dental resin-based materials used for restoring of lost tooth substance contain reactive substances (e.g. methacrylates, initiators etc.). Precautions should be taken in all patients to decrease the leakage and direct exposure of these substances. This should be considered when the patient has a known allergy. Dentures and orthodontic baseplates may contain Phtalates and Bisphenol A, known as xenoestrogens. The amount of released substances is, however, considered to be low and therefore adverse effects in patients may be rare. The dentist should be aware of that, and know what to tell the patient when a concern about this comes up. Still, the awareness and knowledge of adverse effects toward those materials are limited and more clinical studies are needed. URI: http://hdl.handle.net/10037/4205 File(s) in this item: 1

Abstract: Bonding materials are essential for modern restorative dentistry (i.e composite restorations and composite cements). Leakage from composite resin-based materials has been investigated and it is shown that 5-10 % of the residual monomers are released within the first seven days from the moment the restauration is made. Studies has also stated that monomer leakage can be a problem for patients and dental personal, and allergies can occur. Only a few studies have been focused on the degradation and erosion process of bonding materials. Since bonding agents are insufficiently studied concerning leakage of monomers, the aim of this study was to investigate leakage of monomers from bonding materials after light curing by using Gas Chromatography - Mass Spectrophotometry (GC-MS). The MS-instrument was equipped with an Electron Ionization (EI) and a Chemical Ionisation (CI) ion source that enabled to choose the most sensitive and selective method for the different compounds. Compounds with polar functional groups (i.e. –OH groups) were derivatized and analysed as their trimethyl silyl ethers. The light cured materials were immersed in water and in ethanol. In both cases the analysis demonstrated the leakage of several different compounds, even compounds that were not listed in the Material Safety Data Sheets (MSDS) of the actual bonding material.
