Abstract
Objectives: To assess the influence of patient age on tooth sensitivity, bleaching effectiveness, and the self-perception and psychosocial impact of dental esthetics following in-office tooth bleaching with 35% hydrogen peroxide.
Methods: This parallel study categorized 56 subjects by age into early adulthood (18-25 years) and middle-aged (40-65 years) groups. The bleaching agent was applied in a single 45-minute session, spanning two bleaching sessions at a 1-week interval. Bleaching effectiveness assessment used upper incisors and canines. A shade guide (VITA Bleachedguide 3D-MASTER) and a portable spectrophotometer evaluated color changes. A visual analog scale and verbal rating scale recorded tooth sensitivity during and up to 48 hours after the bleaching procedure. The Psychosocial Impact of Dental Aesthetics Questionnaire measured the self-perception and psychosocial impact of the bleaching protocol. Student t-test, Fisher exact test, Mann-Whitney, multivariate analysis of variance, chi-square, two-way repeated measures analysis of variance, and the Wilcoxon test (α=0.05) verified the data.
Results: Early adulthood subjects demonstrated a significant increase (17%) in the risk of tooth sensitivity (p=0.038), and the highest pain levels occurred 1 hour after the bleaching session (p<0.01). Nonetheless, early adulthood subjects showed improved bleaching effects 30 days after the procedure when compared to the middle-aged subjects, even though the overall perception of the psychosocial impact of dental esthetics was more evident in middle-aged subjects.
Conclusions: Patient age influenced in-office bleaching outcomes. Both age groups reported esthetic satisfaction, but early adulthood subjects (18-25 years) experienced a more substantial whitening effect, greater dentin sensitivity, and higher psychological impact. Conversely, middle-aged subjects (40-65 years) had a better overall perception of the psychosocial impact of dental esthetics.
期刊介绍：
Operative Dentistry is a refereed, international journal published bi-monthly and distributed to subscribers in over 50 countries. In 2012, we printed 84 articles (672 pages). Papers were submitted by authors from 45 countries, in the categories of Clinical Research, Laboratory Research, Clinical Techniques/Case Presentations and Invited Papers, as well as Editorials and Abstracts.
One of the strong points of our journal is that our current publication time for accepted manuscripts is 4 to 6 months from the date of submission. Clinical Techniques/Case Presentations have a very quick turnaround time, which allows for very rapid publication of clinical based concepts. We also provide color for those papers that would benefit from its use.
The journal does not accept any advertising but you will find postings for faculty positions. Additionally, the journal also does not rent, sell or otherwise allow its subscriber list to be used by any other entity
