Emma Göranson är doktorand vid odontologiska fakulteten, Malmö universitet och specialist i ortodonti i Region Östergötland. Hon berättar här om sin forskning om bettavvikelsers påverkan på livskvalitet, och om jämlik tandregleringsvård.
Munnen och kroppen hör ihop
3hForskningsintresset för samband mellan tandhälsa och sjukdomar i kroppen har ökat sedan 80-talet. Flera studier tyder på att bakterier och inflammationsämnen från munnen kan påverka sjukdomsförloppet vid exempelvis diabetes typ-2, reumatism och kolorektal cancer.
Frisk- och riskfaktorer vid karies
3hTandvården vill hellre förebygga hål än att borra bort dem. Men att riskbedöma vilka som har störst sannolikhet att utveckla karies är komplext och involverar många vitt skilda faktorer. Mer kunskap behövs.
Spottet speglar hur kroppen och munnen mår
3hHur spännande är spott? Oändligt spännande anser, två Lundaforskare som dyker djupt ner i spottets universum för att söka svar på varför sjukdomar i munhålan drabbar vissa. Svaret kan delvis finnas i spottet, i ett ämne som fungerar som kroppens väktare och helt egna antibiotika.
Går du för ofta till tandläkaren?
3h– Vi behöver bli bättre på att identifiera patienter som löper störst risk att utveckla svår karies eller tandlossning, och sluta överbehandla dem som inte är i riskzonen, säger Gunnel Svensäter, övertandläkare och professor i oral biologi vid Malmö universitet.

Och om vi märker att barn inte mår bra måste vi agera, säger Gunilla Klingberg, professor i barn- och ungdomstandvård.
Sexuella övergrepp kan ligga bakom tandvårdsrädsla
3hTandvårdsrädsla kan ibland bero på tidigare sexuella övergrepp. Genom att vara uppmärksamma på signaler och fråga har tandvården möjlighet att hjälpa sina patienter. Det kan göras genom att lotsa dem vidare till professionell hjälp. Samtidigt är det också viktigt att bygga upp ett förtroende mellan tandläkare och patient och skapa en vårdsituation som upplevs som mindre hotfull.
Metaller som försvinner
3hBrutna ben måste fixeras för att läka rätt. En del kan gipsas medan andra behöver fästas med skruvar och plattor. Skruvar som ibland måste opereras bort efter att benet har läkt. Tänk om de kunde försvinna av sig själva efter en tid? Silvia Galli, tandläkare och forskare vid Malmö universitet, undersöker möjligheterna att använda skruvar av magnesium.
Tandreglering, smärta och livskvalitet

Vad avgör om implantaten håller?
3hDen tekniska utvecklingen och ökad kunskap har gjort dagens tandimplantat väldigt hållbara. Men komplikationer kan ändå uppstå. Riskfaktorer är saker som dålig benkvalitet, rökning och att gnissla tänder. Även den mänskliga faktorn spelar in.
”Nu förstår jag bättre min smärta”
3hEn digital smärtskola för ungdomar med käksmärtor har fått positiv respons av patienterna. Efter en pilotstudie på specialistkliniker vill skaparna nu sprida den till allmäntandläkare, vårdcentraler och skolkuratorer.
Menar vi samma saker?
3hFör att forskare och vårdpersonal runt om i världen ska kunna jämföra patienter, tillstånd och behandlingar behövs gemensamma klassificeringar. Bildligt talat kan man inte jämföra äpplen med päron – om man tänkt att man ska jämföra just päron med päron. Smärta i ansiktet berör flera olika specialiteter inom tand- och sjukvård och 2019 publicerades ett gemensamt klassifikationssystem.
Röntgendiagnostik med kraftigt minskad stråldos
3hDen röntgen som kallas Cone Beam Computed Tomography (CBCT) har blivit allt vanligare för dentalt bruk eftersom den kan bidra med mer diagnostisk viktig information än vad konventionell röntgenundersökning kan. En nackdel med CBCT är att den ger högre strålningsdoser. Men ny forskning visar att stråldosen i vissa fall sänkas med hela 80 procent och ändå ge tillfredsställande resultat.
Tonsillernas gerillakrig mot HPV
3hHumant papillomvirus (HPV) är världens vanligaste sexuellt överförda infektion. Runt 90 procent av alla HPV-infektioner läker ut av sig själv, men det finns några få HPV-typer som i sällsynta fall inte läker ut och som orsakar cancer – bland annat tonsillscancer.

The high density of cation-anion pairs determined by the aluminum concen
Removing energy with an exoskeleton reduces the metabolic cost of walking
19hEvolutionary pressures have led humans to walk in a highly efficient manner that conserves energy, making it difficult for exoskeletons to reduce the metabolic cost of walking. Despite the challenge, some exoskeletons have managed to lessen the metabolic expenditure of walking, either by adding or storing and returning energy. We show that the use of an exoskeleton that strategically removes kine
Control of polarization in bulk ferroelectrics by mechanical dislocation imprint
19hDefects are essential to engineering the properties of functional materials ranging from semiconductors and superconductors to ferroics. Whereas point defects have been widely exploited, dislocations are commonly viewed as problematic for functional materials and not as a microstructural tool. We developed a method for mechanically imprinting dislocation networks that favorably skew the domain st
Free coherent evolution of a coupled atomic spin system initialized by electron scattering
19hFull insight into the dynamics of a coupled quantum system depends on the ability to follow the effect of a local excitation in real-time. Here, we trace the free coherent evolution of a pair of coupled atomic spins by means of scanning tunneling microscopy. Rather than using microwave pulses, we use a direct-current pump-probe scheme to detect the local magnetization after a current-induced exci
Mitochondrial NADP(H) generation is essential for proline biosynthesis
19hThe coenzyme nicotinamide adenine dinucleotide phosphate (NADP + ) and its reduced form (NADPH) regulate reductive metabolism in a subcellularly compartmentalized manner. Mitochondrial NADP(H) production depends on the phosphorylation of NAD(H) by NAD kinase 2 (NADK2). Deletion of NADK2 in human cell lines did not alter mitochondrial folate pathway activity, tricarboxylic acid cycle activity, or

An expected characteristic feature of quantum criticality is power-law behavior of thermodynamic quantities as a function of a nonthermal tuning parameter close to the quantum critica
Local conditions magnify coral loss after marine heatwaves
19hClimate change threatens coral reefs by causing heat stress events that lead to widespread coral bleaching and mortality. Given the global nature of these mass coral mortality events, recent studies argue that mitigating climate change is the only path to conserve coral reefs. Using a global analysis of 223 sites, we show that local stressors act synergistically with climate change to kill corals
Hemispheric asymmetry in ocean change and the productivity of ecosystem sentinels
19hClimate change and other human activities are causing profound effects on marine ecosystem productivity. We show that the breeding success of seabirds is tracking hemispheric differences in ocean warming and human impacts, with the strongest effects on fish-eating, surface-foraging species in the north. Hemispheric asymmetry suggests the need for ocean management at hemispheric scales. For the no
