A higher number of missing teeth correlated with an inferior MP in older children. Children with a higher number of caries rated their oral health less favourably. Older females and those who broke the test material into smaller sizes were also more likely to report a worse OHRQoL, suggesting that the time allowed to reduce food appears to be a more influential factor on children' perception of oral health than their ability to break down the test material into smaller sizes. Moreover, the subjectivity of functional domain and artificial nature of chewable test material could have influenced the test sensitivity.
