Dental Aptitude Test For Dentistry and Sample Questions

Generally, you lay foundation of your life style during your academic career. No doubt there are some exceptions but when you want to join dental care as your profession you need to join the dental schools. The dental aptitude test (DAT) plays the most vital role when you apply for admission.

You may take this sample test to see your aptitude for the dental career. But it shall also make you familiar with the structure of dental test that you may face in your real life psychological session.

Administration of Dental Aptitude Test

When you go through a real DAT session, you must keep in mind the current practices of dental schools. Generally, dental care institutions organize tests on national or state levels. For example, in Canada the these tests are prepared by keeping in view the requirements of ten Canadian dental care schools.

Furthermore, the candidates appearing in DAT are accepted by U.S. dental schools. Contrary to that the scores of the USA dental aptitude tests are not accepted in Canada because the USA tests do not include a manual dexterity component.

The information about practices in your country shall help you to score better. You may be required to go through the tests after applying for the dental care schools. In other countries you may appear in the dental aptitude tests before applying for such admissions.

How to Prepare for Dental Aptitude Test?

No doubt practice of dental aptitude tests or the related tests helps you to go through the session with better scores.

However, you must be able to solve difficult quantitative reasoning problems by using easy algebra and common-sense probability reasoning. You should be capable to solve natural sciences issues. Your capability to analyze patterns with the minimal available information and your reading comprehension, word identification, and use key word identification also help you to score higher.

Most of the aptitude tests attract you in the time trap for their length and difficulty at different points. You need not only to learn a number of important subjects but also be a master to break down complex problems into simple plain questions to avoid such time traps.

Topics you Need to Learn

  • Biology: Action Potential, Classical genetics, Smooth Muscle, TCA cycle, ATP, Liver function, Mineral, Embryology, Thyroid Hormones, Enzymes and their effects etc
  • Organic Chemistry:- Alkanes, Esters, Alcohols, aromatic rings, Granger reagents, Wolff-Kushner reduction reaction, Hofmann’s rule, Isomers, Acids, Aromatic rings etc.
  • Natural Sciences: Inorganic Chemistry: Electrons, Bronsted-Lowry Theory, Titration, Haber reaction, Empirical formula, pH Log Scale, Shell formula, Ground state, Homogenous/ Heterogeneous reactions, reactants
  • Quantitative Aptitude: Quadratic formula, Fraction, Exponent Powers, rational/Irrational numbers, Problems on ages.

Sample Dental Aptitude Test Questions

Some of the following sample questions are given with answers while others demand you to concentrate upon your previous knowledge and go through your notes to find the answers. They are fairly easy. Stretch your brain muscles and if you can't, please use the ‘Feedback Form’ and I shall respond.


Describe Wolff-Kushner reduction reaction?


The reduction of aldehyde and ketones to alkanes. Condensation of carbonyl compounds with hydrazine forms the hydrazones and treatment with base induces the eduction of carbon coupled with oxidation of the hydrazine to gaseous nitrogen, to yield the corresponding alkane.


The ratio of ages of Swati and Varun is 2:5. After 8 years their ages will be in ratio 1 : 2. The difference in their present ages in years is

A) 24

B) 26

C) 29

D) 32


Let swati’s age = 2x

and varun’s age = 5x(2x+8)/(5x+8) = ½

So x=8

Swati’s age = 16 years

Varun’s age = 40 years

Difference in their present age = 24 years


During recovery from oxygen debt, which of the following does not occur?

A) Glucose is converted to private.

B) Private is converted to lactate.

C) Lactate is transported to the liver.

D) Lactate is converted to private.

E) Oxaloacetic acid is converted to citric acid.


Transport of a substrate across a cell membrane with the aid of carrier molecules along the substrate's concentration gradient is defined as

A) Phagocytosis.

B) Facilitated diffusion.

C) Active transport.

D) Osmosis

E) Simple diffusion.


Which of the following statements concerning oxidative phosphorylation is incorrect?

A) Cyanide inhibits oxidative phosphorylation.

B) Oxygen is the final electron acceptor.

C) Oxidation of NADH typically yields 2 ATP.

D) New ATP yield is 36 ATP per glucose molecule.

E) CO2 is released.


According to the second law of thermodynamics

A) Matter can neither be created nor destroyed.

B) Conversion of heat to work leads to less organization.

C) Entropy is unchanged or increases following a thermodynamic process


The raw materials of the earth's primitive environment (the "primordial soup") did not include....

A) Phosphorus.

B) Salts.

C) Methanol.

D) Water.

E) Ammonia.
