Changes in dental esthetic perceptions of patients subjected to in-office tooth bleaching

Abstract

<div class="WordSection1"><p><strong>Objective</strong>: This study evaluated changes in the esthetic perceptions of patients subjected to in-office tooth bleaching. <strong>Material</strong><em> </em><strong>and</strong><em> </em><strong>Methods</strong>: Fifty participants included in a clinical trial evaluating the in-office tooth bleaching answered two questionnaires about their dental esthetic perceptions. The participants answered the Orofacial Esthetic Scale (OES) questionnaire and the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) before and after treatment. The average scores observed at baseline were compared with those recorded after tooth bleaching using the paired t-test or the Wilcoxon signed rank test (α = 0.05). <strong>Results</strong>: Improvement in tooth color (reduction of 5.1 shade guide units) had a positive impact on patients’ perceptions. According to PIDAQ, tooth bleaching significantly increased the psychological impact and dental self-confidence; and reduced esthetic concerns. The OES demonstrated improvements in participants’ satisfaction for all questions, except for the one on “facial appearance”. However, higher effect size was observed for the question related to tooth color, as expected. <strong>Conclusion</strong>: Tooth bleaching was associated with an overall improvement in dental esthetic perception, even when only tooth color was affected.</p><p><strong>Keywords</strong></p><p>Patient-reported outcomes; Randomized Controlled Clinical Trials; Tooth Bleaching.</p></div>

Clinical performance of whitening on devitalized teeth: a retrospective observational study

“…However, this limitation does not affect the validity of the findings, since factors that compromise the stability of whitening treatment can be evaluated in a reduced period, and clinically relevant factors might be suggested. In addition, few studies have evaluated the clinical performance of whitening treatment and its correlation with the patient satisfaction/perception with different samples and results [17,18,[20][21][22][23].…”

Patients' awareness, attitudes, and experiences regarding tooth whitening methods: a survey study

“…Избелването на зъбите е неинвазивна техника за подобрение на цвета на зъбите с висока успеваемост (14,17). Избелващият ефект се постига с химични продукти на основата на пероксид, като при разграждането му се генерират свободните радикали, които разграждат органичната структура на пигментните молекули в дентина и той изсветлява (7).…”

“…За статистическата обработка на резултатите са приложени дескриптивни методи и непараметрични методи за проверка на хипотези. Красивата усмивка подобрява външния вид на лицето на пациентите и така повишава тяхното самочувствие и социална интеграция (9,17). Проучвания в САЩ показват, че повече от 30% от американците изпитват на недоволство от цвета на зъбите си ( 16) спрямо 20% сред пациенти от Англия (2).…”

One‐year follow‐up evaluation of reservoirs in bleaching trays for at‐home bleaching

“…Minimum intervention principles and the search for improved facial cosmetics have increased the search for dental bleaching protocols in dental offices. Apart from being a very conservative cosmetic treatment, dental bleaching protocols have been associated with increased quality of life for the patients who undergo this procedure 1,2 …”
