Fotografisk diagnostik av Molar Incisor Hypomineralization: Test av validitet och reliabilitet

Molar Incisor Hypomineralization definieras som ett specifikt tillstånd orsakat av störningar i den tidiga fasen av emaljbildning av en eller flera permanenta första molarer med eller utan involvering av permanenta incisiver. Tidigare studier har visat att standardiserad intraoral fotograferingsteknik kan vara användbar för epidemiologiska studier av emaljdefekter. Denna studies syfte var att utveckla och utvärdera en fotografisk klassificering av allvarlighetsgraden av Molar Incisor Hypomineralization genom att studera metodens validitet och reliabilitet. 164, 10-12 åriga svenska barn granskades fotografiskt avseende prevalensen av Molar Incisor Hypomineralization. Först granskades endast första molarens ocklusalyta, därefter ocklusal- och buckalyta.

En bild ljuger aldrig? : En studie om digitaliseringens inverkan på trovärdigheten i fotografier

The concept of the photographic truth has had a special status for almost 200 years. Yet with the emerge of digital technology and especially digital photography there has been a loss of the particular connection photography has had in reference to reality. The aim of this study is to see in what ways digitalization has affected the credibility of photography from the perspective of professionals in the field of photography. The digital technology that has enabled the large-scale manipulation of photographies is not, however, the main reason for the decreased credibility of photography. The ongoing discussion about the available possibilities concerning digital imagery and manipulation has had a far more powerful effect on the concept of the photographic truth.

Normering av test av intraoral stereognosi och tvåpunktsdiskrimination : Hos barn i åldrarna 5;6 - 7;0 år

The oral sensory ability in children can be assessed through test of intraoral stereognosis and two-point discrimination. Currently, these two tests are not frequently used in clinical settings, and normative data are not always available. The aim of this study was to establish normative data for these two tests in children aged 5;6 to 7;0 years. Further, intention was to compare the results with respect to age and gender. In total 103 children participated, 49 boys and 54 girls.

En ny metod för intraoral röntgenundersökning på häst :

A method for equine intra oral radiology has been tested. In the study, both a digital system with an intraoral sensor connected to a laptop and a system utilizing image plates and digital developing was tested, initially on cadaver sculls and finally on sedated horses. The digital sensor was not considered viable for this purpose, while the system with image plates and digital developing worked very well. Two different techniques, i.e. parallel and bisectris, are suggested for the best visualization of different parts of the teeth. Intra carious injections of Mixobar oesophaghus contrast fluid was found useful when evaluating the extent of carious lesions. Compared to extra oral radiology, the new method had several advantages and can be used both in clinic and field practices..

Orthodontic diagnostics and measurements on digital study models made with an intraoral scanner

Introduktion: Modellanalys har traditionellt gjorts på fysiska gipsmodeller. Idag finns ny teknik som möjliggör framställning av digitala modeller utan behov av konventionella avtryck. Syftet med den här studien är att undersöka tillförlitligheten hos digitala modeller framställda med en intraoral scanner, patientupplevelsen och olika tidsaspekter förenade med tekniken. Metod: På ett urval av 20 vuxna personer gjordes både konventionell avtryckstagning och en intraoral scanning (TRIOS, 3Shape) av bettet för framställning av gipsmodeller och digitala modeller. Den kliniska tidsåtgången mättes och personerna besvarade ett frågeformulär gällande sin upplevelse av metoderna. Fyra observatörer diagnostiserade bettrelationer och utförde ortodontiska mätningar på gipsmodeller med ett skjutmått och digitala modeller med OrthoAnalyzer Orthodontics (3Shape, Danmark).

DIGITAL VISUALISERINGSTEKNIK : möjligheter, för- och nackdelar

Ever since the development of the pc and their software, in the early 80´s,architects way of work have changed a lot. Nowadays most of the architectspresent all their works digitally and not with hand drawn material, as they didbefore the pc boom.Digital visualisation technique pushes the limits, when it is about presentingarchitecture projects virtual reality.This report studies how digital visualization technique is used among thearchitects today.Together with architects from ABAKO architect firm in Gothenburg, Sweden,interviews has been made to give answers about what they think about digitalvisualization technique. What are the opportunities, advantages- anddisadvantage with this digital technique?The answers from the architects, together with work that has been done withdigital visualization technique in a project called Project Sofiedal, shows thatthis technique has big opportunities when it comes to create nice looking VRpresentations. The result in this report also shows that this digital technique ismore time demanding compared to hand drawn presentations.The investigation shows that digital visualization technique is a goodcompliment when it is about showing the citizens how future projects willaffect the surrounding.

A standardized method for evaluating trueness and precision of intraoral scanners ? in vitro accuracy

Bakgrund. En gyllene standard för att bestämma noggrannheten för intraorala scannrar existerar inte. Intraorala scannrars prestanda som ges av olika leverantörer är inte fullt jämförbara. Det finns ett behov att standardisera och ta fram oberoende försöksupplägg för att kunna jämföra intraorala scannrar. Mål. Målet med studien var att beskriva och utvärdera en ny metod för att bestämma noggrannheten av intraorala scannrar genom ett standardiserat in vitro testförsök och att använda metoden för att beräkna noggrannheten på en kommersiell intraoral scanner. Material och metod.

Hur väl överensstämmer tandslitage på intra-orala foton med klinisk registrering?

Syftet: Målet med studien var att utvädera kliniska intraorala foton som diagnostisk metod för att bedöma tandslitage (attrition, erosion och abrasion) och jämföra dessa bedömningar med kliniska registreringar. Material och metod: Studien genomfördes på Tandvårdskolan i Malmö, där man slumpmässigt valde ut 30 vuxna patienter. Dessa patienter undersöktes med avseende på tandslitage (attrition, erosion och abrasion) och kliniska foton togs. En månad efter kliniska registreringen gjordes en bedömning av de kliniska fotona, utan att ha kännedom om resultatet av de kliniska registreringarna. Båda undersökarna har på samtliga patienter utfört klinisk registrering och fotobedömning oberoende av varandra. Intra- och interobservatör överensstämmelse uppskattades genom Cohen?s Kappa- koefficient. Resultatet: Intraobservatör överensstämmelsen mellan bedömningar av foton och kliniska registreringar var måttligt-till-god med ett P-värde på 0,039-0,046.

FORL : Feline Odontoclastic Resorptive Lesions

This report was written in an attempt to summarize old and new theories and scientific results regarding FORL (Feline Odontoclastic Resorptive Lesions). Several different kinds of treatment are presented in this study. Among them teeth extraction and crown amputation seems to give the best long-term results. It seems clear that the domestic cat of today have no trouble digesting dry foods without their teeth. The most accurate way to diagnose FORL is by using intraoral dental radiology technique.

COMPARATIVE STUDY OF HYDROLYSIS PERFORMED WITH MODERN MICROWAVE TECHNIQUE AND THE TRADITIONAL METHOD

Proteins are vital to all cells in the body. They consist of long chains of amino acids. To be able to study the amino acid composition of a protein it is necessary to hydrolyse it, followed by separation and quantification. When the protein is hydrolysed, in this case ß-lactoglobulin, the protein is divided into individual amino acids. The method that traditionally has been used to hydrolyse proteins takes 24-72 hours to complete.
