Impact of At-Home Dental Bleaching on Quality of Life Using OHIP-14

This prospective clinical study aims to evaluate the clinical efficacy of an at-home dental bleaching protocol and its impact on oral health-related quality of life using objective color measurements and patient-reported outcomes. Changes in tooth color will be assessed using CIELAB parameters (L\*, a\*, b\*) and the Whiteness Index for Dentistry (WID), while quality of life will be evaluated using the OHIP-14 questionnaire.
