Effects of orthodontic treatment on the oral health-related quality of life of Malagasy patients

Orthodontic treatment can have a significant impact on patient's quality of life. The objective of this study was to analyze the effects of orthodontic therapy on the quality of life of Malagasy patients. A descriptive cross-sectional study was conducted among 106 individuals undergoing orthodontic treatment in Antananarivo and Mahajanga, Madagascar, between April and June 2024. Sampling was exhaustive: all patients present during the survey period were included. The independent variables were age and gender, while the dependent variable was the reported change in quality of life. Data were collected using a pre-established, tested, and validated questionnaire. The tools used to assess quality of life included the OHIP-14 (Oral Health Impact Profile), GOHAI (General Oral Health Assessment Index), and CPQ (Child Perception Questionnaire). Statistical analysis was performed using SPSS software version 20.0 for Windows. More than two-thirds of participants (77.4%) reported a change in their quality of life during treatment. The most frequently reported effects included stress (41.5%), feelings of self-consciousness (41.5%), sleep disturbances (45.3%), difficulties with speech (74.5%), chewing (86.8%), and pain. Orthodontic treatment appears to affect the quality of life of Malagasy patients negatively. Orthodontists should consider these impacts to enhance patient management and comfort throughout the treatment process.
