A revised and updated edition of this successful text offers new material on plastic restorations.
With increasing emphasis on restoration, as opposed to extraction, and growing public awareness of the importance of primary teeth, the first edition was one of the first books to illustrate in detail the various scientifically proven clinical techniques.
The authors are at the Leeds Dental Institute.
It is 41 years since the first edition of this book was published.
In that time there have been so many developments in
our understanding of dental disease, in materials, and in
techniques so that there is now very little of that first edition
remaining except the basic philosophy for managing
patients with dental disease. This philosophy has several
parallel threads which weave together.
• Dentists primarily look after people with dental problems
– not just mouths or teeth.
• An understanding of the disease processes is fundamental
to their management.
Composites are engineered or naturally occurring materials made from two or more
constituent materials with significantly different physical or chemical properties which
remain separate and distinct within the finished structure. Basically, they can be
categorized into two major types, i.e., structural composites with outstanding
mechanical properties and functional composites with various outstanding physical,
chemical or electrochemical properties. They have been widely used in a wide variety
of products, e.g.
This book is a complete study guide that fits the needs of engineers as well as those of newcomers to the field. Its most important feature is the way the author allows students with a little background in mathematics to go through all the topics presented without getting lost or discouraged. The purpose is achieved with a simple but efficient strategy: an easy to follow level is the main body of the book and a lot of examples provide the reader with all the tools necesary to grasp the basics. The higher level material (advanced mathematics) is therefore not indispensable...

The conservation of artefacts and buildings has
a long history, but the positive emergence of
conservation as a profession can be said to
date from the foundation of the International
Institute for the Conservation of Museum
Objects (IIC) in 1950 (the last two words of
the title being later changed to Historic and
Artistic Works) and the appearance soon after
in 1952 of its journal Studies in Conservation.
The introduction of the technology for bonded composite repairs of metallic
airframe structures could not have come at a more opportune time. Today, many
countries are facing the challenge of aging aircraft in their inventories. These
airframes are degrading due to damage from fatigue cracking and corrosion.
Repair with dependable techniques to restore their structural integrity is
mandatory. The concept of using bonded composite materials as a means to
maintain aging metallic aircraft was instituted in Australia approximately thirty
The conservation of glass, as of all artefacts,
falls into two main categories: passive conservation,
the control of the surrounding environment
to prevent further deterioration; and
active conservation, the treatment of artefacts
to stabilize them.
Definitions and scope of pediatric dentistry
Pediatric dentistry is an age-defined specialty that provides
both primary and comprehensive preventive and therapeutic
oral health care for infants and children through adolescence,
including those with special health care needs.1
To become a pediatric dental specialist, a dentist must satisfactorily
complete a minimum of 24 months in an advanced
education program accredited by the Commission on Dental
Accreditation of the American Dental Association (ADA).
Our precious planet is in peril. The economic overshoot of ecological thresholds is seemingly
the order of the day. Yet, it is clearly not enough to lament the excessive economic use and
human domination of ecosystems and sit as if in sackcloth and ashes while romanticizing the
days gone by.
Effective solutions to water quality challenges exist and have
been implemented in a number of places. It is time for a
global focus on protecting and improving the quality of the
world’s freshwater resources. There are three fundamental
solutions to water quality problems: (1) prevent pollution; (2)
treat polluted water; and (3) restore ecosystems.
The science of conserving artworks and other items of cultural significance has undergone considerable
change since 1982 when this series was instigated, mostly involving the development or application of new
materials or techniques. Their understanding by conservators, restorers and students continues, nonetheless,
to depend on familiarity with the underlying scientific principles which do not change and which are clearly
explained in these books.
The body of property rights literature provides a general framework for analyzing
the determinants of corporate share ownership structures.4 The literature emphasizes the
roles of customs, social norms, and law and legal systems in shaping the structure of
property rights and their governance systems. Corporate share ownership can be viewed
as a property rights arrangement through which the owner of the share is entitled to three
categories of property rights. First, the owner has the decision right of deploying
corporate assets, i.e., the control or voting right.
Electrochemical systems—e.g., batteries, capacitors, and fuel cells—are an integral
part of modern technology. Electrochemical techniques, especially potentiometry
and voltammetry, are indispensable for state-of-the-art analysis, and also for fundamental
studies of the properties of solution species and solid phases and materials.
Last, but not least, electrochemical concepts for understanding charge transfer reactions
entered the fields of biochemistry and biophysics.
There are many critical limits in the material available. For example, Senlis -- which sometimes tends
to exaggerate the Taliban and Al Qa'ida challenge as part of its effort to increase aid and NATO/ISAF
troop strength -- provides most of the available maps that give some idea of the progress in the fighting
and the relative balance of Afghan Central government, Pakistani central government, NATO/ISAF,
Taliban, and Al Qa'ida presence and influence.
The end result is necessarily long and complex. The full brief runs over 200 pages.
As may be obvious by now, it is helpful in the understanding of this book to see the earth
as having a single soil (as it has a single atmosphere), nearly all of it 10,000 or more years
“old,” or in development, since the bulk of its surface “parent material” was laid down. In addition to those cited by Hamaker, some other examples of results obtained with
ground gravel (mixed rock) materials may help illustrate the great potential to restore
youthfulness and productive fertility to any and all soil....
This book embraces the most recent developments in modern operative dentistry,
but has attempted to merge these with traditional practice. Students,
colleagues, and general dental practitioners have requested an evidence-based
approach to the practical concepts in modern restorative dentistry. One important
philosophy that is emphasized in this book is that the prevention of
dental caries, restoration failure, and periodontal disease should be the basis
of all operative dentistry.
Teaching silent ﬁlm courses on a regular basis, I’m one of the ﬁrst to
admit that the advent of DVDs has made my job easier. Trying to con-
vince students that the ﬁlm they are watching is not only a cinema clas-
sic, but also as sophisticated and modern as any ﬁlm made in the sound
era, is a particularly hard sell when the print in question is a ‘dupey, ’
ﬁfth-generation 16mm reduction from the 35mm nitrate original, and
dead silent to boot.
Stains caused by dental materials are not uncommon (Figure 7-6).Among the discolorants found in dental materials, metallic ions are
considered to be the most difficult to bleach.The metallic corrosion products may lead to a dark gray or black appearance that will
be visible through the remaining tooth structure, including the root structure (Figures 7-12 and 7-13).The severity of discoloration
and the success of bleaching depend upon the amount of metallic ions penetrating the dentinal tubules.
The sources from which I have drawn the materials for this book are various; they come largely from private
papers, and from articles contributed to magazines and newspapers by contemporary writers, French, English,
and American. I had not at first intended the work for publication, and I omitted to make notes which would
have enabled me to restore to others the "unconsidered trifles" that I may have taken from them.
As far as possible, I have endeavored to remedy this; but should any other writer find a gold thread of his own
in my embroidery, I hope he will look upon it as an evidence...
