2.7 Statistical Analysis
The statistical analysis was conducted using SPSS for Windows software
(version 22.0; IBM Corp., Armonk, NY, USA). The intraobserver
coefficient of variation for all assessments was 0.94. Normality tests
were performed for all variables. Age, gender, parental education
status, dentition period, occlusion type, and DMFT/dmft and ECOHIS-T
results were compared between the HM and control groups using the
Mann-Whitney U test. Correlations between the SOHI, DMFT/dmft,
and ECOHIS-T scores were evaluated using Spearman’s rank correlation
analysis. A p-value < 0.05 was considered significant.
