Abstract

Svrha ovog istraţivanja je in vivo i in vitro procijeniti pouzdanost elektronskog ureĎaja CarieScan Pro, za detekciju karijesa, te vizualne ICDAS metode (The International Caries Detection and Assessment System) u usporedbi s histološkim nalazom. Ispitivanje je provedeno na krunama 40 ljudskih trajnih zuba, predviĎenih za vaĎenje zbog oteţanog nicanja, ortodontskih ili parodontoloških razloga. Jedan uvjeţbani ispitivač ispitao je 72 mjerne točke na okluzalnim plohama koristeći ICDAS kriterije i CarieScan Pro ureĎaj. Nakon ekstrakcije su ponovljena mjerenja i zubi su histološki klasificirani. Podatci su statistički obraĎeni Chi-kvadrat testom i MeĎuklasnim korelacijskim testom, pri razini značajnosti p<0,05. Izračunata je osjetljivost, specifičnost i točnost metoda detekcije karijesa. Ponovljivost mjerenja za CarieScan Pro ureĎaj, u in vivo uvjetima izraţena meĎuklasnim korelacijskim koeficijentom (Interclass Correlation Coefficient), iznosila je 0,848. PronaĎena je statistički značajna razlika izmeĎu in vivo i in vitro. Najsnaţnija je korelacija izmeĎu ispitivane metode i histološkog nalaza, izraţena Cohenovom Kappom, postignuta kod vizualne ICDAS metode (0,613). CarieScan Pro ureĎaj in vivo je pokazao negativnu korelaciju (-0,037), a in vitro nešto bolju korelaciju (0,199). Najtočnijom se pokazala ICDAS metoda (95,9 %). Na temelju ovog se istraţivanja moţe zaključiti kako je ICDAS metoda pouzdanija u dijagnostici karijesa u odnosu na istraţivani elektronski ureĎaj. Korelacija s histološkim nalazom veća je kod ICDAS metode, kao i točnost i osjetljivost metode u odnosu na CarieScan Pro ureĎaj.

Abstract (english)

Purpose of this reasearch is to evaluate clinical perfomance of electronic device CarieScan Pro and ICDAS method in caries detection using histological gold standard. The study was made on occlusal surfaces of 40 human permanent teeth which were indicated for extraction because of tooth erruption problems, orthodontic and parodontic reasons. A trained examiner assessed 72 measurement points on occlusal surfaces using ICDAS criteria and CarieScan Pro device. After a tooth extraction, measurements were repeated and the samples were histologically evaluated. The results were statistically analyzed with Chi-square test and Interclasse correlation test, with significance level p<0.05. The sensitivity, specificity and accuracy for these caries detection methods were calculated. The repeatibility of measurements for CarieScan Pro device in vivo (Interclass Correlation Coefficient) was 0.848, and in vitro 0.888. The statistically significant difference was found between in vivo and in vitro measurements. The strongest correlation between the examined method and histological validation expressed by Cohen’s Kappa is achieved in the visual ICDAS method (0.613). CarieScan Pro in vivo had negative correlation (-0.037) and in vitro showed somewhat better result (0.199). The most accurate was ICDAS method (95.9%), while in vivo CarieScan Pro had the accuracy of 86.1% and in vitro of 87.5%. Based on this research, ICDAS method is more reliable in caries detection than the electronic device. The correlation with histological validation is higher with the ICDAS method, as well as the accuracy and sensitivity of te method in relation to CarieScan Pro device.
