Abstract

Konvencionalnom kemomehaničkom obradom korijenskih kanala nije moguće u potpunosti očistiti zidove korijenskih kanala od zaostatnog sloja i debrisa s bakterijama. Zato su se razvili različiti sustavi za aktivaciju sredstva za ispiranje, od kojih su najnoviji laseri. LAI je metoda aktivacije sredstva za ispiranje stvaranjem kavitacijskih mjehurića i agitacijom tekućine čime sredstva za ispiranje mogu doseći teško dostupna područja i tamo djelovati antimikrobno ili ukloniti zaostatni sloj.
U ovome radu obrađen je slučaj traume gornjeg lijevog lateralnog sjekutića s velikom periapikalnom radiolucencijom koja je bila vidljiva na RTG snimci. Zub je nakon mehaničke instrumentacije Reciproc instrumentom R50 dezinficiran LAI tehnikom, Er, Cr: YSGG laserom, valne duljine 2780 nm, koničnim RFT2 nastavkom uz fiziološku otopinu kao sredstvo za ispiranje. Nakon toga je zub obturiran biokeramičkim punilom i odgovarajućom Reciproc R50 gutaperkom te je pristupni kavitet zatvoren staklenoionomernim ispunom (Equia Fil). Stari kompozitni ispun zamijenjen je novim ispunom. Na kontrolnoj RTG snimkci nakon 6 mjeseci vidi se cijeljenje periapikalnog procesa.
Odgovarajuća mehanička obrada i dezinfekcija korijenskih kanala važni su za uspjeh endodontskog liječenja zuba. U opisanom prikazu slučaja, nakon strojne instrumentacije korijenskoga kanala zuba 22, dezinfekcije Er, Cr: YSGG laserom, punjenja te izrade trajnog ispuna, nakon šest mjeseci vidljivo je cijeljenje periapikalnog procesa, a zub je klinički asimptomatski.

Abstract (english)

It is not possible to fully clean the walls of the root canal from the smear layer and bacteria-filled debris with a conventional chemo-mechanical root canal treatment. Therefore, various systems for the activation of irrigants are being developed, the most recent of which is lasers. The LAI method activates irrigants by creating cavitation bubbles and agitating the irrigants which reach areas difficult to access, have an antimicrobial effect and remove the smear layer.
This paper describes a case of trauma of the upper left lateral incisor, with a large periapical radiolucency visible on an X-ray image. After a mechanical instrumentation with the R50 reciprocating instrument, the tooth was disinfected with the LAI technique and the Er, Cr: YSGG laser of a 2780 nm wavelength, using conical RFT2 fiber with saline. The tooth was obturated with a bioceramic sealer and the appropriate Reciproc R50 gutta-percha, while the access cavity was sealed with a glass ionomer filling (Equia Fil). The old composite filling was removed and a new one was made. A control X-ray after 6 months showed the healing of the periapical area.
A suitable mechanical treatment and the disinfection of root canals are important for the success of the endodontic treatment of teeth. In the present case report, following mechanical instrumentation of the root canal of tooth #22, disinfection with Er, Cr: YSGG laser, obturation and permanent filling, the healing of the periapical area is visible after six months and the tooth is clinically asymptomatic.
