INBDE study guide
INBDE · Work through your exam, one topic at a time.
The Integrated National Board Dental Examination (INBDE) is the current national licensure examination for dentists in the United States, administered by the Joint Commission on National Dental Examinations (JCNDE) of the American Dental Association. It replaced the older two-part NBDE format and is designed to test whether a candidate can apply biomedical, behavioral, and clinical science knowledge to realistic patient care rather than recall isolated facts. The INBDE study guide has 4 sections and about 1,398 words.
01Diagnosis and Treatment Planning
Treatment planning is a sequence of disciplined data gathering, not a hunch about a tooth. Start with the chief complaint in the patient's own words, then expand into a history of the present illness (onset, location, duration, character, aggravating and relieving factors, timing, severity), medical and medication history, allergies, and social history including tobacco and alcohol.

Most clinical dentistry is disease management, not just restoration. Caries management by risk assessment drives the plan: high-risk patients get fluoride varnish, sealants on at-risk pits and fissures, silver diamine fluoride for arresting cavitated lesions (noting black staining and avoiding use near pulpal exposure), xylitol, diet counseling, and short recall intervals.

Dental caries is a biofilm-driven, sugar-modulated disease; mutans streptococci and lactobacilli are associated with initiation and progression, but the ecological shift of the whole plaque community matters more than a single pathogen. Periodontitis involves a dysbiotic subgingival biofilm with organisms such as Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia, and Treponema denticola, coupled with a destructive host inflammatory response.

The five principles to know are patient autonomy, nonmaleficence, beneficence, justice, and veracity. Most exam vignettes resolve to autonomy plus veracity: the competent patient decides, and the dentist must tell the truth about diagnosis, prognosis, and options.
