Design outcomes

Primary

MeasureTime frame
To assess the correlation and agreement between plaque measurements obtained through ImageJ software and those recorded using manual plaque index scoring.Timepoint: 0 week, 1 weeks, 2 weeks

Secondary

MeasureTime frame
1.To determine intra- and inter-examiner reliability for plaque quantification using ImageJ. 2.To evaluate the sensitivity of ImageJ in detecting plaque area changes compared to manual plaque indices. 3.To assess the feasibility, time-efficiency and practical applicability of ImageJ as a digital plaque assessment method for clinical research. 4.To compare the variability and reproducibility between digital and manual measurement techniques. Timepoint: 0 week, 1 weeks, 2 weeks
