Official title
Clinical Evaluation of Color Changes (CIELAB),Whiteness Index (WID), and Oral Health-Related Quality of Life (OHIP-14) Following At-home Dental Bleaching: A Prospective Clinical Study
Overview
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.
Detailed description
Tooth bleaching is a widely used minimally invasive treatment for improving dental aesthetics. Objective evaluation of color changes is essential and is commonly performed using the CIELAB color space and derived indices such as the Whiteness Index for Dentistry (WID).
This study will be designed as a prospective, non-randomized before-after clinical trial to evaluate the clinical efficacy of an at-home dental bleaching protocol and its effect on tooth color. The protocol will consist of the at-home application of 16% carbamide peroxide delivered through custom trays for six weeks, with one daily application lasting 90 minutes.
The primary objectives of this study will be to quantify color changes and bleaching effectiveness, as well as to evaluate oral health-related quality of life and the subjective impact of treatment. Additional analyses will include a detailed assessment of the behavior of the individual CIELAB parameters and their variation during treatment, the analysis of correlations between WID and the individual color parameters, and the evaluation of oral health-related quality of life using the OHIP-14 questionnaire.
Interventions
- Drug Carbamide peroxide 16%
Blanqueamiento dental domiciliario utilizando peróxido de carbamida al 16% aplicado mediante férulas individualizadas durante seis semanas, con una aplicación diaria de 90 minutos. Los cambios en el color dentario se evaluarán mediante mediciones espectrofotométricas de los parámetros CIELAB (L\*, a\*, b\*) y del Índice de Blancura para Dentistas (WID). La calidad de vida relacionada con la salud oral también se evaluará mediante el cuestionario OHIP-14.
Primary outcome measures
- Change in Whiteness Index for Dentistry (WID) [Time frame: Baseline to 6 weeks]
Secondary outcome measures (2)
- Changes in CIELAB color parameters (L*, a*, b*) [Time frame: Baseline, 3 weeks, and 6 weeks]
- Oral Health-Related Quality of Life (OHIP-14) [Time frame: Baseline and 6 weeks]
