To evaluate changes in tooth color for 2 age cohorts (younger cohort,
1950-1952; older cohort,
1930-1932) over a mean observation period of 8 years.
This article was published in the following journal.
The aim of the present study was to evaluate the effect of prior microabrasion on the teeth color change and tooth bleaching effectiveness. Eight sound molars were mesio-distally sectioned and the hal...
The aim of the present study was to evaluate colorimetric changes and tooth sensitivity in adolescents and young patients submitted to tooth bleaching with 20% and 35% hydrogen peroxide. A randomized,...
To evaluate the effect of 5% potassium nitrate containing 2% sodium fluoride and 10% strontium chloride on tooth sensitivity and color change after at-home bleaching treatment across 3 months of follo...
The objective of this research was to identify risk factors for tooth loss in two birth cohorts, quinquagenarians and septuagenarians, after up to 10 years of clinical observation.
A wide literature shows a strong social gradient in tooth loss according to income, education and occupation, in both developed and developing countries. It has been shown associations between tooth l...
Objective:The aim of this clinical study was to evaluate tooth color alteration (ΔE) and tooth sensitivity (TS) in patients that used two commercial brand-whitening dentifrices for four w...
The goal of our study is to examine eye color at birth and the longitudinal change in eye color of preterm and full-term newborns.
The purpose of this study was to compare the whitening effect of a toothpaste containing blue pigment with a conventional toothpaste and with at-home tooth bleaching; evaluate the subject'...
The present study investigates whether it is possible to achieve equally satisfactory results between 37.5% hydrogen peroxide gel and 6% gel for teeth bleaching. A prospective, double-blin...
Objectives: This study will determine the clinical efficacy of bleaching agent 37% carbamide peroxide compared to 35% hydrogen peroxide on the change of color scores in anterior superior t...
Longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-95 school year. The Add Health cohort has been followed into young adulthood. (from http://www.cpc.unc.edu/projects/addhealth accessed 08/2012)
Any change in the hue, color, or translucency of a tooth due to any cause. Restorative filling materials, drugs (both topical and systemic), pulpal necrosis, or hemorrhage may be responsible. (Jablonski, Dictionary of Dentistry, 1992, p253)
Two extensive fibrous bands running the length of the vertebral column. The anterior longitudinal ligament (ligamentum longitudinale anterius; lacertus medius) interconnects the anterior surfaces of the vertebral bodies; the posterior longitudinal ligament (ligamentum longitudinale posterius) interconnects the posterior surfaces. The commonest clinical consideration is OSSIFICATION OF POSTERIOR LONGITUDINAL LIGAMENT. (From Stedman, 25th ed)
Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary.
The pathologic wearing away of the tooth substance by brushing, bruxism, clenching, and other mechanical causes. It is differentiated from TOOTH ATTRITION in that this type of wearing away is the result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It differs also from TOOTH EROSION, the progressive loss of the hard substance of a tooth by chemical processes not involving bacterial action. (From Jablonski, Dictionary of Dentistry, 1992, p2)
Geriatrics is the branch of medicine that is concerned with the diagnosis and management of diseases and disorders that occur in old age. A specialty is required because of the frequency of co-morbidities in these patients and the reduced strength of the...
