“Good” (Estimate: −5.01, p < 0.001) or “Very good” (Estimate: −5.46, p < 0.001) had significantly association with the number of dental caries compared to those with poorer self-perception, with “Satisfactory” ratings approaching significance (Estimate: −5.21, p < 0.001).
Self-perceived oral health status showed a clear trend: participants who rated their oral health as “Good” (Estimate: −5.28, p = 0.005) or “Very good” (Estimate: −6.12, p = 0.003) had significantly lower dental erosion scores compared to those with poorer self-perception, with “Satisfactory” ratings approaching significance (Estimate: −3.85, p = 0.052).
