Summary

This study compared two types of orthodontic appliances—removable braces and clear aligners—in 24 children aged 6 to 12 with crossbite. Researchers measured changes in speech, oral hygiene, pain, anxiety, and quality of life over two weeks. The goal was to understand how each appliance affects children's daily function and well-being.

Inclusion Criteria: \- Children aged between 6 and 12 years who applied to the Clinics of the Departments of Pedodontics and Orthodontics at Marmara University Faculty of Dentistry were included in the study. * Patients were required to present with anterior cross-bite type malocclusion. * Participants had to be cooperative, native Turkish speakers, and have no systemic disease, syndrome, craniofacial anomaly, or known allergy. * Individuals with no apparent oro-facial anomaly, no hearing or speech impairment, and no reading or language difficulties were included. * Based on clinical and radiographic evaluations, only patients whose malocclusions were determined to be dental in origin (not skeletal) were selected. * Patients who did not require maxillary (palatal) expansion were also included in the study. Exclusion Criteria: * The study excluded patients who had severe periodontal disease, a history of systemic illness, a known allergy to any of the materials used in the study, poor oral hygiene, insufficient cooperation, or who did not agree to attend regular follow-up appointments during the study period. Additionally, individuals with craniofacial anomalies or skeletal-origin malocclusions were not included. Participants with hearing impairments, non-native Turkish speakers, or those with any disease or history of surgery that could affect voice or speech quality were also excluded from the study.
