Oral health-related quality of life in children using the child perception questionnaire CPQ11-14: a review

Objectives: The Child Perceptions Questionnaire 11–14 (CPQ11-14) is the most common and effective indicator of paediatric oral health-related quality of life. The aim of this review was to verify if CPQ11-14 can be considered a valid instrument for assessing the impact of oral health on the quality of life of adolescents for the paediatric population aged between 11 and 14 years old and which dental conditions mainly affect it. Study design: A literature research from Pubmed Medline database was adopted to identify the eligible studies among the published articles related to CPQ 11–14 using keyword search strategy. From 170 initial articles, a total of 128 articles were included for the full text reading. Results: Conditions that mainly interest the oral health-related quality of life are untreated dental caries, dental trauma, increased dental protrusion, wearing orthodontic appliances, and severe periodontal disease. Conclusion: CPQ 11–14 seems to be a solid and valid indicator to measure oral health-related quality of life, because it has been widely tested and validated in several states including developed, developing and underdeveloped countries
