DANB Anatomy, Morphology and Physiology Examination Practice Test
The DANB Anatomy, Morphology and Physiology Examination covers structures and functions relevant to understanding the human body and dentition. Practice questions sample tooth identification and surfaces, eruption patterns, roots and supporting jaw structures, along with basic endocrine, blood, and skeletal anatomy. These concepts help dental assistants interpret anatomical terms and recognize how body systems relate to oral care.
Exam overview
About the DANB Anatomy, Morphology and Physiology Examination Exam
The question bank exercises recognition of permanent and primary teeth, including numbering, position, eruption sequence, and root characteristics. It also tests directional language used to describe tooth surfaces, such as mesial and distal, and the role of the alveolar process in supporting teeth. Body-system questions address physiological functions, including hormone effects on blood glucose and calcium regulation, the contribution of platelets to clot formation, and the organization of long bones and marrow. These skills support accurate communication about oral and general anatomy, understanding basic physiological responses, and relating anatomical landmarks to dental procedures. The sample set includes items across these areas, but does not establish an official topic list or exam weighting.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
Which permanent tooth is normally the first to erupt, at about six years of age?
Show answer
Correct answer: BThe mandibular first permanent molars commonly erupt around age six, often before the incisors. They erupt behind the primary second molars and do not replace a primary tooth.
In the Universal Numbering System for primary teeth, which letter designates the maxillary right first molar?
Show answer
Correct answer: CPrimary teeth are labeled A through T, beginning with the maxillary right second molar as A and proceeding around the arch. The maxillary right first molar is therefore C.
Which permanent tooth typically has the longest root?
Show answer
Correct answer: AThe maxillary canine commonly has the longest root among permanent teeth, providing substantial support for this tooth.
Which gland produces parathyroid hormone, which helps regulate calcium levels in the blood?
Show answer
Correct answer: CThe parathyroid glands secrete parathyroid hormone (PTH), which is a major regulator of blood calcium and phosphate balance.
Which tooth surface is described as mesial?
Show answer
Correct answer: AMesial refers to a tooth surface oriented toward the midline of the dental arch. Distal refers to the direction away from that midline.
Which hormone lowers blood glucose by promoting its uptake into many body cells?
Show answer
Correct answer: BInsulin, produced by pancreatic beta cells, helps lower blood glucose by promoting glucose uptake and storage in responsive tissues.
Which blood component is chiefly responsible for initiating clot formation at an injured vessel?
Show answer
Correct answer: APlatelets adhere to damaged vessel surfaces and aggregate to form an initial plug, helping initiate hemostasis.
How to use this practice test
Access the free practice bank for a session of up to 20 randomly selected questions from the 50 published items. Answer questions on dental anatomy and basic physiology, then use the displayed results to identify which concepts need another review, such as tooth numbering, surface terminology, or hormone function.
Preparation tips
- Practice identifying primary and permanent teeth by Universal Numbering System designation, arch, and position relative to neighboring teeth.
- Sketch a tooth and label mesial, distal, facial, lingual, occlusal, and incisal surfaces; connect each term to its orientation.
- Compare tooth eruption patterns and root features, and review how the alveolar process supports the teeth.
- Make brief function charts for insulin, parathyroid hormone, platelets, and long-bone marrow to distinguish their physiological roles.
