| Popis: | Svrha: Procijeniti pouzdanosti mjerenja ispitivača uređajem za određivanje boje zuba. Materijali i metode: Istraživanje je provelo četvero ispitivača dobro uvježbanih za određivanje boje zuba i rukovanje uređajem za određivanje boje zuba. Odredili su boju zuba i CIE L*a*b* vrijednosti na zdravim i intaktnim gornjim desnim središnjim sjekutićima desetero pacijenata. Svaki pojedini ispitivač mjerio je dva puta središnji dio labijalne plohe svakoga pojedinog ispitivanog zuba s pomoću uređaja za određivanje boje zuba VITA Easyshade® Advance 4.0. Izmjerena je pouzdanost između ispitivača i izračunata su odstupanja u L*a*b* i E vrijednostima. Pouzdanost između ispitivača analizirana je intraklasnim koeficijentima korelacije. Rezultati: Jednosmjerni ANOVA test nije dokazao između četvero ispitivača statistički značajnu razliku u određivanju boje zuba u svim mjerenjima (p > 0,05). Vrijednosti ΔE iznosile su od 3,018 do 5,234. Statistički značajna razlika između ispitivača nije pronađena (p > 0,05), iako su postojale male razlike. Vrijednosti ICC-a između ispitivača bile su visoke i kod svih su se kretale od 0,651 do 0,992 . Zaključak: Rezultati mjerenja pokazali su prihvatljivu pouzdanost mjerenja svih ispitivača uređajem za određivanje boje zuba VITA Easyshade® Advance 4.0. Za pravilno određivanje boje zuba, osim digitalne tehnologije, potrebni su i iskusni ispitivači. Objectives: The aim of this study was to evaluate the inter-observer reliability of dental shade-matching device using an in vivo model. Materials and methods: Four observers who were well trained in color assessment and handling of the dental shade-matching device determined teeth color and CIELab values on maxillary right central incisors in 10 patients with completely healthy and intact dentitions. VITA Easyshade® Advance 4.0 shade-matching device was utilized to measure the central region of the labial surface of all investigated teeth, twice by each observer. The inter-observer reliability of the measurements was observed and deviations between Lab and E values between the observers were calculated. Intraclass correlation coefficients (ICCs) were used to analyze inter-observer reliability. Results: One-way ANOVA showed no statistically significant differences in color measurement of four observers in all the measured values (p>0.05). Delta E values ranged from 3.018 to 5.234. Although some small differences existed, statistically significant differences between the observers were not found (p>0.05). Inter-observer ICCs were very high for all observers (from 0.651 to 0.992). Conclusion: Inter-examiner reliability of measurements using VITA Easyshade® Advance 4.0 shade-matching device was acceptable. Apart from the digital equipment, a well trained observer seems to be crucial in order to achieve correct dental color measurement. |
