The two compounds remained effective at nine months, with a slight rebound of color, and maintained their objective color difference but not the subjective color difference. Patients were satisfied with the bleaching procedure, and this had a positive impact on esthetic perception and a positive psychosocial impact at the nine-month recall.
We used hydrogen peroxide (6%) that was light activated with a hybrid LED/laser and two different protocols (one 36-minute application vs three 12-minute applications each for two sessions). These approaches were equally effective. There were no differences in absolute risk of sensitivity; both groups reported mild sensitivity.
In the last years the focus in dentistry has shifted to an "esthetic dentistry" approach, where patients are concerned about reaching a better look of their teeth. Vital tooth bleaching is a technique with immediate results, which improves the appearance and patient's self-esteem. The aim of this study was to recognize personality characteristics determined by the Millon Index of Personality Styles of participants looking for tooth bleaching and to correlate them to satisfaction with the treatment. Forty participants were included and filled out the Millon Index of Personality Styles form before treatment. Expectation about tooth bleaching was quantified from 1 to 5. Patients were treated with bleaching agent according to manufacturer's directions. One week after treatment, the patient's satisfaction was quantified from 1 to 5. Prevailing personality characteristics were determined. Expectations and satisfaction values of all patients were correlated with each of the presented personality scales by Spearman Rho test. Ten scales prevailed over their counterpart. Median of patient's expectation was 2 and satisfaction 4. Only the score of a single characteristic (extraversing) showed statistically significant correlation with patient satisfaction. Patients looking for tooth bleaching treatment seem to have common personality characteristics. Almost all of them wanted to achieve a moderate change in teeth color and the result of the treatment was usually satisfactory.
Given that most clinical parameters investigated were similar between all groups during the follow-up, the repair of RC and AM restorations is a good clinical option because it is minimally invasive and can consistently increase the longevity of restorations.
Artículo de publicación ISIThe aim of this prospective, blind, and randomized
clinical trial was to assess the effectiveness
of repair of localized clinical defects
in amalgam restorations that were initially
scheduled for replacement. A cohort of 20
patients with 40 (Class I and Class II) amalgam
restorations that presented one or more clinical
features that deviated from the ideal
(Bravo or Charlie) according to US Public
Health Service criteria, were randomly assigned
to either the repair or the replacement
group—A: repair, n = 19; and B: replacement, n
= 21. Two examiners who had calibration
expertise evaluated the restorations at baseline
and 10 years after according to seven
parameters: marginal occlusal adaptation, anatomic
form, surface roughness, marginal
staining, contact, secondary caries, and luster.
After 10 years, 30 restorations (75%) were
evaluated (Group A: n = 17; Group B: n = 13).
Repaired and replaced amalgam restorations
showed similar survival outcomes regarding
marginal defects and secondary caries in patients
with low and medium caries risk, and
most of the restorations were considered clinically acceptable after 10 years. Repair treatment
increased the potential for tooth longevity,
using a minimally interventional
procedure. All restorations trend to downgrade
over time
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
