Introduction to operative dentistryPresentation Transcript
“ Operative dentistry is the art and science of
the diagnosis ,treatment and prognosis of the defects
of teeth that do not require full coverage restorations
for correction. Such treatment should result in the
restoration of proper tooth form, function and
esthetics while maintaining the physiologic integrity of
the teeth in harmonious relationship with the adjacent
hard and soft tissues, all of which should enhance the
general health and welfare of the patient ”

• Earlier concept of “extension for prevention.”
• Increased knowledge of prevention methods,
advanced clinical techniques, and improved
restorative materials have provided a more
conservative approach to the restoration of teeth.
More conservative approaches are available for
(1) many typical restorative procedures (Classes I,
II, III, IV, and V)
(2) diastema closure procedures
(3) esthetic or functional correction of malformed,
discolored, or fractured teeth; and
(4) actual replacement of teeth.
results of conservative treatment are
retention of more intact
tooth structure and less trauma to the
pulp tissue and
contiguous soft tissue.
Dynamics of Operative Dentistry
• The development of the high-speed
handpiece played a dramatic role in the more
conservative and efficient removal of tooth
structure for restorative procedures.
• Mechanical bonding by etching enamel and dentin
and use of bonding systems have led to the
development of many new composite restorative
materials and conservative restorative bonding
• Benefits of sealants are becoming more widely
accepted for the prevention of pit-and-fissure
• Increased knowledge about the carious process
and the beneficial effects of multiple fluoride
applications has resulted in a decrease in caries
• Increased research on biomaterials has led to the
introduction of vastly improved dental materials.
• All of the above mentioned factors have played an
important role in the development of operative
• Ultimate result is improved oral health for all
US POPULATION (increase by 146
• Percentage of older adults in the
population and also life expectancy will
increase substantially in the future.
• Emphasis will shift from the needs of
young to concerns and demands of
middle-aged individuals & older adults.
• With more discretionary income and more
health care benefits for the adult segment
of society, the demand for future dental
services should increase.
General and Dental Health of
the U.S. Population
• The general health of the U.S. population is good.
• Americans generally have good dental health.
• Incidence of caries has decreased ;primarily due
to increased exposure to fluoride.
• Fluoridation of community water systems began in
Grand Rapids, Michigan, in 1945.
• Caries remains the most common chronic
• Missing teeth : In last several decades, there has
been a steady reduction in edentulism and
numbers of teeth lost per person.
• Edentulism and the number of teeth present are
strongly influenced by age
Age >75 yrs
• Periodontal Status: periodontal Attachment
loss (number of affected people and
severity) increased with age.
• Gingival recession also increased with age.
• Oral Cancer: Oral and pharyngeal cancer is
the sixth most common neoplastic disease.
• The number of total “active private
practitioners” is expected to increase from
156,921 in 2002 to 172,097 in 2020.
• There will be fewer dentists treating more
patients who will have retained more teeth.
Projected Need for Operative
• Increased need of operative dentistry in
i. restorations for teeth with new carious
ii. restorations for teeth with root caries;
iii. restorations to replace existing, faulty
iv. restorations to enhance the esthetic
appearance of patients.
Public’s Perception of Dentistry
• The public’s perception of dentistry is another
factor that will influence whether the increased
numbers of teeth and increased need for
operative services will be converted to increased
• The number of dental visits has increased in
the past several years.
• Recent surveys shows that New older adults
and future older adults not only will possess
positive perceptions about dentistry and
dental health, but also will have the
economic means to secure the dental care
• Research in operative dentistry is now occurring in
• Use of lasers in dentistry may lead to a new
mechanism for welding dental alloys or altering tooth
structure in tooth preparation.
• Improvements in composites, adhesive
systems, castable ceramics, and computer-
generated restorations could result in significant
decrease in the use of metal alloy systems in
• Efforts also are being made to develop an anticaries
• The future of operative dentistry is
• The emphasis of the profession will
shift to care for the senior adult
segment of the population and also to
nonsurgical treatments for caries.
