Institutes and Research Divisions
National Institute of Dental Research

Mission

Established in 1948, the National Institute of Dental Research is the primary sponsor of oral, dental and craniofacial research and related training in the U.S. Its mission, to improve adn promote oral health, is accomplished by conducting and coordinating research to establish the causes, develop better diagnostic methods and treatments, and ultimately find ways to prevent or substantially lower the risk of developing oral and craniofacial conditions; and by maintaining a cadre of trained scientists to conduct basic, clinical, and applied research.

Institute scientists and those affiliated with grant-supported NIDR programs have made great strides in improving the Nation's oral health through advances in diagnosis, treatment and prevention. NIDR has organized its efforts into three major components: the Division of Extramural Research, which provides grant and contract funds to the scientific community for research and research training; the Division of Intramural Research, centered in NIDR's laboratories and clinics in Bethesda, Md.; and the Division of Epidemiology and Oral Disease Prevention, which sponsors epidemiologic studies of oral diseases, engages in controlled clinical trials of potential preventive agents an regimens; and promotes their dissemination to the dental profession and the general public.

Together, NIDR's three organizational divisions conduct and support basic research in biochemistry, microbiology, immunology, physiology, anatomy, histology, cell and molecular biology, genetics, pathology, bioengineering, and the social and behavioral sciences. NIDR also sponsors clinical, epidemiological and applied studies in the oral health sciences.

The institute promotes the timely transfer and adoption of research findings by the public, health professionals, and the research community. NIDR collaborates with other U.S. Government organizations within and outside the NIH, with health professional and voluntary associations and industry, and with health professional and voluntary associations and industry, and with investigators internationally in developing and implementing research programs of mutual interest.

 

Important Events in NIDR History 1931--PHS created a Dental Hygiene Unit at NIH and designated Dr. H. Trendley Dean as the first dental research worker. His primary function was to apply principles of epidemiology to a series of community studies on the oral disease known as mottled enamel. His research on fluoride showed not only its relation to mottled enamel, but also its influence on tooth decay.

1945--Following fluoridation of the water supply in Grand Rapids, Mich., annual examinations of children were begun to study the effects of fluoride on the development of dental caries.

1948--On June 24, P.L. 80-755, the National Dental Research Act, created NIDR and the National Advisory Dental Research Council. On September 16, the institute was established.

1949--The first meeting of the National Advisory Dental Research Council was held on January 10. The institute-supported grants program was initiated, and the first grants and fellowships were awarded.

1954--Results of the first 10 years of the Grand Rapids study firmly established water fluoridation as a safe, effective, and economical procedure for the control of dental caries.

On October 30 the first meeting of the Board of Scientific Counselors was held. This board was established to provide advice to NIDR on matters of general policy, particularly from a long-range viewpoint, as they relate to the intramural program.

1958--The Laboratory of Biochemistry was established to conduct research studies on the chemistry and structure of collagen, elastin and other proteins. President Eisenhower signed the appropriations bill which included provisions to finance the construction of a building for the dental institute.

1960--On September 21 the cornerstone was laid for the dental institute building (Building 30) at NIH.

1961--On May 26, DHEW Secretary Abraham A. Ribicoff dedicated the new NIDR building.

1962--The first grant for a multidisciplinary study of cleft palate was awarded to the University of Pittsburgh Health Center.

1963--Fifteen years of scientific accomplishment by NIDR were cited by scientists, administrators and health educators June 14 in a special anniversary observance.

Biographical Sketch of NIDR Director Harold C. Slavkin, D.D.S.

In July 1995 Dr. Slavkin, former director of the Center for Craniofacial Molecular Biology at the University of Southern California School of Dentistry, was sworn in as the sixth NIDR director.

Born in Chicago, Ill., on March 20, 1938, he received his B.A. in 1961 and his D.D.S. in 1965 from the University of Southern California. After completing postdoctoral training at USC, he was named chairman of the department of biochemistry and nutrition at the university's school of dentistry in 1969. He served in various capacities at USC over the next 26 years, including chief of the laboratory for developmental biology in the Gerontology Center, chairman and program director of the graduate program in craniofacial biology, and director of the Center for Cranifacial Biology, a position he held for 6 years prior to his appointment as NIDR director.

In his last position Dr. Slavkin directed a team of scientists investigating the genetics of normal and abnormal craniofacial, oral, and dental development. His own studies focused on the developmental processes underlying a number of congenital and acquired craniofacial and oral defects. He was also responsible for creating the first Ph.D. program in the U.S. in craniofacial biology, a program he chaired for 10 years.

He has been active in programs to promote science appreciation and literacy at the elementary, middle, and high school levels. He helped initiate a program sponsored by the National Science Foundation that gives high school students an opportunity to work on a research project at a university. He served as executive producer and writer for a Public Broadcasting Service film called A Lifetime of Change, shown at the 10th annual conference of the International Society of Developmental Biology and the Academy of Motion Pictures, Arts and Sciences in Beverly Hills. He also collaborated with PBS on the production of Genetic Engineering, Why in the World? and with other educational film companies in the making of Development and Differentiation and Intercellular Communication.

A grantee since 1966, Dr. Slavkin has been a member and chair of NIDR's Board of Scientific Counselors and served as acting chief of NIDR's Laboratory for Developmental Biology and Anomalies. He also served on the NIDR Blue Ribbon Panel that formulated recommendations to shape the future of the institute's Division of Intramural Research.

He serves on the editorial boards of the International Journal of Developmental Biology, Differentiation, Oral Diseases, and Current Opinion in Dentistry. A member of numerous professional organizations, he has authored more than 90 book chapters and over 180 publications in the field of developmental and craniofacial molecular biology.

 

Division of Extramural Research and Special Programs NIDR is the primary sponsor of oral, craniofacial, and dental research and research training in the U.S. Through its extramural program, the institute provides funds for biomedical and behavioral research outside its intramural laboratories and clinics in Bethesda. Funds are made available in the form of grants, cooperative agreements and contracts which support scientists working in institutions throughout the United States and in foreign countries. These scientists carry out research ranging from laboratory studies on the basic causes of oral and dental diseases to clinical trials of new public health measures for treatment and prevention. Funds are also awarded to train new researchers in certain needed disciplines. In addition to the Office of the Director, which incorporates the Office of Policy and Coordination, and Research Training and Career Development, the extramural program consists of two components: 1) the Program Development Branch with seven parts: Caries, Nutrition and Fluoride; Periodontal Diseases; Craniofacial Development and Disorders; Biomaterials, Pulp Biology and Dental Implants; Oral Soft Tissue Diseases and AIDS; Behavioral, Pain, Oral Function and Epidemiology; and Salivary Glands Research and Oral Biology Centers and 2) the Program Operations Branch, including the Scientific Review, Grants Management, and Contracts Offices. Brief descriptions are presented in the following paragraphs.

The Caries, Nutrition and Fluoride Program

Supports research on the causes, early diagnosis, prevention and treatment of caries. High priority areas include total fluoride intake, fluoride metabolism and action, caries prevention and control, fluorosis, and fluoride retention in bone and its relationship to aging and bone diseases. In the area of nutrition, research is targeted to defining the role of nutrition in oral health and the influence of compromised oral/craniofacial health on nutrition and general health.

The Periodontal Diseases Program

Supports research on the etiology, pathogenesis, prevention, diagnosis, and treatment of periodontal diseases. Areas of particular interest include microbial virulence factors involved in periodontal diseases, development of assays to identify periodontal pathogens, and the role of host immune response in both the prevention and pathogenesis of periodontal diseases. The program also supports research to identify behavioral, psychosocial, environmental, and genetic risk factors for periodontal diseases.

The Craniofacial Development and Disorders Program

Supports research in cellular and molecular biology, protein chemistry, and biomineralization to improve our understanding of the causes and treatment of congenital craniofacial anomalies such as cleft lip and palate, dentofacial malrelations, and ameliogenesis imperfecta. Areas of special interest include defining the human genes for craniofacial malformations, identifying factors that regulate craniofacial development, and testing orthodontic and surgical strategies for correcting malformations.

The Biomaterials, Pulp Biology and Dental Implants Program

Supports the development of biocompatible materials for preventing oral disease and restoring damaged tissues. The pulp biology component encourages research on the development and physiology of this soft tissue and its hard dentin covering, including studies on sensitivity and pulp inflammation. Implant research focuses on improving the implant-tissue interface, developing improved implant materials, and supporting clinical trials.

The Oral Soft Tissue Diseases and AIDS Program

Fosters basic and clinical research on diseases that affect the soft tissues of the mouth, including viral, fungal and bacterial infections, and oral cancer. The AIDS component focuses on oral changes as diagnostic and prognostic indicators of human immunodeficiency virus infection and disease progression, salivary functions in HIV infection, and the role of saliva in preventing the oral transmission of HIV.

The Behavioral, Pain, Oral Function and Epidemiology Program

Supports research to identify the psychosocial and prevention factors that influence the onset and progression of oral diseases and disorders and how these conditions affect the quality of life. The pain component supports studies to enhance the understanding, management and prevention of chronic and acute orofacial pain conditions such as temporomandibular disorders and burning mouth syndrome. Other program interests include research and epidemiological studies on such areas as taste, smell, thermal and tactile sensitivity disorders, and on normal and impaired oral motor function.

The Salivary Glands Research and Oral Biology Centers Program

Focuses on improving knowledge of the development, structure, function, and diseases of the salivary glands and to determine the influence of salivary constituents on oral health.

NIDR also funded 28 center grants for $18 million, approximately 15 percent of the EP budget. The center awards supported noncategorical Research Centers in Oral Biology, Oral Health in Aging Centers, Periodontal Diseases Research Centers, Caries Research Centers, Materials Science Research Centers, Clinical Dental Research Core Centers, and Regional Research Centers for Minority Oral Health. These centers not only contribute new information to oral health sciences, but provide stimulating environments for collaborative efforts and training researchers and educators.

The Research Training and Career Development Program

Supports training and career development opportunities in all the program areas of oral health research.

Under the Program Operations Branch, the Scientific Review Office coordinates initial scientific peer review of a variety of large research grant applications such as centers and program projects, training and career development applications, small grants and conference grant applications, and coordinates and conducts project site visits and other review procedures. The Grants Management Office is responsible for all fiscal management activities associated with the review, negotiation, award, administration, and termination of grants. The Contracts Management Office has responsibility for all matters relating to solicitation, negotiation, award, and administration of research and development contracts.

 

Contracted Research Studies

NIDR's contracted research activities of the extramural and intramural research programs and the Epidemiology and Oral Disease Prevention Program fund studies to readily translate advances in the basic sciences to disease-oriented applied research as well as to provide support complementary to basic science investigations. Interagency agreements with other Federal agencies have also been utilized to provide support toward these NIDR goals.

 

Division of Intramural Research NIDR's intramural research program conducts basic and clinical research directed toward increasing fundamental knowledge of oral diseases and related disorders. The latest techniques in biomedical science--particularly those of molecular biology, immunology and cell biology--are used. Areas under investigation include the biochemistry, structure, function and development of bone, teeth, salivary glands and connective tissues; the role of bacteria and viruses in oral disease; genetic disorders and tumors of the oral cavity; studies on the cause and treatment of acute and chronic pain; and the development of new and improved diagnostic methods. The intramural research program has approximately 300 employees and guest researchers in eight laboratories, a dental clinic and a pain research unit.

The Clinical Investigations and Patient Care Branch conducts research related to the diagnosis, prevention and management of oral and dental diseases. Primary efforts are directed at understanding regulation of events involved in salivary secretion. Other studies focus on xerostomia (dry mouth), establishing criteria for evaluating salivary gland status and developing treatment for hypofunctional glands.

The Bone Research Branch studies the development and structure of bones, teeth and cartilage. Emphasis is placed on acquired heritable disorders of the skeleton through research in bone and cartilage cell biology, skeletal tissue metabolism and matrix molecules--major components of most tissues and critical factors in oral tissue development, function and health.

The Neurobiology and Anesthesiology Branch has as its primary interests clinical and basic research on pain mechanisms, the development of new methods of assessing pain, and evaluating new approaches to pain control. Collaborative studies, including research on pain associated with cancer and diabetes, have been initiated with other institutes.

The Laboratory of Oral Medicine conducts basic and clinical research on viral infections, autoimmune disorders and endocrine diseases. Studies focus on development of transgenic mice to study genes and proteins of HSV and human immunodeficiency virus. Research is also aimed at cloning and sequencing autoantigens, which play a role in triggering autoimmune diseases such as insulin-dependent diabetes mellitus.

The Laboratory of Developmental Biology investigates the roles and gene regulation of the extracellular matrix, a key component of connective tissue, and other cell interaction systems in embryonic development and related processes. Research focuses on such areas as normal and abnormal embryonic development of craniofacial and other tissues, cancer metastasis, and wound healing.

Research in the Laboratory of Cellular Development and Oncology is directed toward understanding the role of growth and regulatory factors in oncogenesis. Studies focus on molecular mechanisms responsible for conversion of normal cells to a malignant state.

Scientists in the Laboratory of Immunology conduct basic research on mechanisms of acute and chronic inflammatory diseases such as arthritis, periodontal disease and AIDS. Understanding the pathways of inflammation will enable investigators to devise methods to interrupt this process and ultimately halt the tissue destruction characteristic of these disorders.

Research in the Laboratory of Microbial Ecology is concerned with human infectious diseases and host immunity. Studies focus on efforts to define the disease-causing mechanisms of microbial organisms, to understand interactions between these organisms and their human host, and to develop methods to protect against disease.

 

Division of Epidemiology and Oral Disease Prevention This division conducts research on the etiology, distribution, and epidemiology of a broad range of oral conditions and facilitates the rapid transfer and adoption of disease prevention and oral health promotion measures by the public and the profession. DEODP consists of three branches.

The Molecular Epidemiology and Disease Indicators Branch develops, evaluates, and refines various types of cost-effective genetic and biological markers and clinical indicators for use in epidemiologic studies of oral and craniofacial conditions as well as hundreds of systematic diseases that affect oral health. Oral markers and indicators will be used to predict or detect those at highest risk of developing oral and craniofacial conditions.

The Disease Prevention and Health Promotion Branch plans and conducts analytical, experimental, and community intervention research to identify, develop, and evaluate methods for the control and prevetion of orofacial diseases and conditions, especially in high-risk populations and among special care groups. The branch also plans and conducts research designed to promote oral health and encourages transfer of scientific knowledge of disease prevention and health promotion to appropriate target groups.

The Analytical Studies and Health Assessment Branch analyzes patterns of oral diseases and disorders and the need for and utilization of dental treatment and dental delivery systems.
