What are the DANB exams?

Congratulations on your decision to pursue certification in dental assisting! The DANB (Dental Assisting National Board) exams are your next hurdle. Exactly what can you expect with the DANB exams?

What is the Dental Assisting National Board (DANDB)?

The DANB exams are based on content validation, an analysis of the duties commonly performed in actual dental assisting practice. DANB offers five different certifications: NELDA (National Entry Level Dental Assistant, CDA (Certified Dental Assistant), COA (Certified Orthodontic Assistant), CPFDA (Certified Preventive Functions Dental Assistant, and CRFDA (Certified Restorative Functions Dental Assistant).

The DANB component exams are administered on computer at Pearson VUE test centers. All exams are multiple-choice format containing from 80 questions to 210 questions depending on the exam. The time allotted also varies from test to test with a range of 60 minutes to 165 minutes. Specific information on each of exams, including registration information, exam outlines with topics covered, and reference materials can be found at

Most DANB exams use computer adaptive testing (CAT). CAT adapts to the examinee’s ability level and customizes the exam for a more accurate measurement. Each exam begins with a question on par with the passing standard. If it is answered correctly, the difficulty level increases. If answered incorrectly the level of difficulty becomes easier. The final score is based on the difficulty of the questions that were presented and passed.

Official exam results and certificates will be mailed within 2 to 3 weeks after the exam. Candidates can verify DANB credentials using the online Credential Verification tool.

DANB's Certified Restorative Functions Dental Assistant - FAQ Sample Questions

The mature cementum is comprised of how many groups of fibers:

Correct Answer:

the mature cementum, which is a vital component of the periodontium that covers the roots of teeth, is characterized by its composition including two distinct groups of fibers. these fibers are crucial for the functional integration of the tooth with the surrounding alveolar bone, providing necessary support and attachment.

the first group, known as group i fibers, primarily includes the intrinsic fibers. these intrinsic fibers are synthesized by the cementoblasts, which are cells responsible for the formation of cementum. these fibers are completely embedded within the cementum and do not extend into the periodontal ligament. their main role is to contribute to the thickness and continuity of the cementum layer, enhancing its protective and supportive functions.

the second group, group ii fibers, comprises the extrinsic fibers, more commonly referred to as sharpey’s fibers. these fibers are initially produced by the fibroblasts of the periodontal ligament and are partially embedded into the cementum, while the rest extend into the alveolar bone. sharpey’s fibers are critical for anchoring the tooth to the bone, thus playing a pivotal role in the stability and distribution of forces to the tooth during mastication.

understanding the structural organization and the roles of these fiber groups in the cementum not only highlights the complexity of tooth tissue architecture but also underscores the importance of cementum in dental health and function. the interplay between these fibers ensures that the tooth remains securely anchored in its socket, thereby facilitating efficient function and longevity of the teeth.

Composites are classified based on which of the following?

Correct Answer:
amount of filler

composites, which are materials made from two or more constituent materials with significantly different physical or chemical properties, are classified based on several factors. one key factor in their classification is the amount of filler content. fillers are particulate additives incorporated into the composite to enhance its properties and performance. the amount of filler in a composite significantly affects its strength, durability, and aesthetic qualities, making it a crucial classification criterion.

fillers not only improve the mechanical properties of the composite, such as its strength and wear resistance, but also influence its thermal and electrical properties. the type and amount of filler used can determine the application of the composite in various industries, including aerospace, automotive, construction, and healthcare, particularly in dental restorations.

besides the amount of filler, other classification factors for composites include the filler particle size, which affects the surface smoothness and handling of the composite; the method of polymerization, which impacts the curing and final properties of the composite; and the matrix chemistry, which defines the overall interaction between the filler and the polymer matrix.

it is important to differentiate between classification criteria and properties of composites. properties such as water absorption, radiopacity, and compressive strength, while essential for determining the suitability of a composite for specific applications, are not classification criteria. instead, they are outcomes that reflect the performance of the composite under various conditions and are heavily influenced by the composite's formulation, including the types and amounts of fillers used.

in summary, while composites possess various properties like chemical resistance, physical robustness, and mechanical strength, these attributes stem from how the composites are classified—primarily by the amount of filler. this classification not only helps in understanding the potential applications and performance of composites but also aids in their development and innovation for specific industrial needs.
