The impact of tooth-borne vs computer-guided bone-borne rapid maxillary expansion on pain and oral health–related quality of life: a parallel cohort study
Introduction: The primary aim of this study was to investigate and compare perceived pain intensity and oral health–related quality of life (OHRQOL) results during the activation phase of rapid maxillary expansion (RME), with tooth-borne and bone-borne devices. In addition, a secondary aim of this study was to evaluate the correlation between pain scales and the shortened Oral Health Impact Profile (OHIP-14) questionnaire. Methods: Thirty-six subjects (16 girls and 20 boys) with a mean age of 12.3 years (standard deviation, 0.82 years) were randomized into 2 groups.
