Om mig

Docent och universitetslektor i Cariologi. Undervisar på grundutbildningen
tandhygienist- och tandläkarprogrammet samt forskar inom ämnesområdet
Cariologi.
Disputerade 2009 med en avhandling om optiska metoder i kariesdiagnostiken
”Optical based technologies for detection of dental caries”. Olika
optiska instrument i kariesdiagnostiken innebär att man med olika
våglängdsområden kan belysa tand och kariesangrepp och kvantifiera
skillnader mellan frisk-sjuk vävnad. Oftast finner man ett kariesangrepp på
ett mycket tidigt stadium, innan ögat eller några av våra vanligt
förekommande undersökningsmetoder finner karies. Eftersom man lyser på
tanden med icke-hälsovådliga strålar kan man upprepa undersökningen om
och om igen och med korta intervaller.
Optiska metoder i kariesdiagnostiken innebär att vi bl. a har undersökt
olika våglängdsområden och vilka som lämpar sig bäst att använda om vi
vill finna karies i tandens olika vävnader. Optiska metoder kan också
användas för att utvärdera olika förebyggande åtgärder i
kariessjukdomen, t ex om vi vill testa en ny tandkräm, probiotika
eller ozon. Metoderna går också att använda om man vill utvärdera
olika behandlingsstrategier som är mest effektiva att förebygga sjukdom.
Övrig forskning och samarbete med andra forskargrupper vid
Karolinska Institutet och Danderyds sjukhus syftar till att undersöka
om en fetmaoperation kan påverka munhälsa.
Ett annat samarbete är med Umeå universitet där forskning pågår om
huruvida genetiska defekter i immunsystemet kan kopplas till varför vissa
barn får mer svårbehandlad karies.
