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

Detaljert beskrivelse
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.

Eksperimentell: At-Home Dental Bleaching
Los participantes serán sometidos a un tratamiento de 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.

Oral Health-Related Quality of Life (OHIP-14)
Tidsramme: Baseline and 6 weeks
|
Oral health-related quality of life will be assessed using the OHIP-14 questionnaire at baseline and after 6 weeks of at-home dental bleaching.
Changes in OHIP-14 scores will be used to evaluate the impact of treatment on patients' oral health-related quality of life.
