| Summary: | Newly introduced ICDAS II as a visual method, laser fluorescence as another
technique that have ability to quantify early mineral loss of tooth structure and intra oral
radiograph, are methods can be used in the clinic. To provide standardization for comprehensive
caries management at an early stage, all methods supposed to be tested between users. The
objective of this research is to evaluate the repeatability of each system. It is a comparative cross
sectional study using 100 extracted permanent teeth without obvious cavitation (premolar &
molar) that were collected and stored in thymol solution. The teeth were embedded on the wax
block and labeled with numbers. All 5 surfaces were examined by 5 examiners using visual
(ICDAS II), laser fluorescence (LF) and radiographic examination. The data were then analyzed
to measure intra and inter examiner repeatability using Cronbach’s alpha and inter-item
correlation matrix. Intra-examiner repeatability for all examiners was >0.7. Chronbach’s α value
for inter-examiner repeatability for ICDAS II was >0.8 on 3 surfaces except on buccal and
lingual. LF exhibit repeatability of >0.8 on all surfaces. Radiograph shows a low value of inter
examiner repeatability (<0.7). Lecturer examiners showed the highest agreement followed by
undergraduate students for inter-item correlation while the 2nd and 3rd reading of LF displays
the best agreement. ICDAS II score favors more non-invasive treatment compared to LF.
ICDAS II showed good repeatability except on buccal and lingual surfaces. In line with some
of the previous study, ICDAS II is applicable for caries detection in daily clinical basis. Laser
fluorescence exhibits the highest repeatability while the radiograph showed weak interexaminer
repeatability. Treatment decisions of ICDAS II propose more preventive treatment
for early caries lesions compared to laser fluorescence. |
