Orthodontist Interview Questions

21 Best Interview Questions To Study

1. What Are The Basic Functions of The Human Nervous System? How Does An Orthodontist Manipulates Them While Treating His or Her Patients?

Sample Answer

Sir, primarily, there are three basic functions of the human nervous system, which are:

  • Sensory Input: The human mind gathers information through the five human senses. For example, visuals, voices, feelings, pain, etc.
    Integration: The information collected through the sensory organs is processed by the human brain to generate optimal responses
  • Motor Output: Appropriate responses are generated following the information processed

Treating jaw disorders or irregularities in the teeth is a painful process and requires several painful treatments. Thus, to save the patient from unbearable pain, orthodontists use anesthesia, which restricts the ability of the brain to process information, especially which is related to pain.

2. What Is Your Understanding Of The Dislocated Jaw? Tell Some Its Common Symptoms.

Sample Answer

Sir, a dislocated jaw is an irregularity in which the jaw is unsettled and is not at its original position. This is caused due to injuries, assaults, accidents, etc. Several signs tell if a patient has a dislocated jaw, which are:

  • Facial swelling
  • The jaw appears to be jutted outwards
  • Difficulty in speaking and breathing
  • The feeling of numbness in the entire face or some specific portion
  • Loosening of teeth, frequent gum bleeding, and pain in the jaw

3. As An Orthodontist You Will Be Required To Operate Upon The Teeth, Jaws, and The Overall Skull Region Of Humans. Can You Tell Something About The Different Bones Existing In Human Skull?

Sample Answer

Sure, sir. The human skull is made up of 29 different bones that are aligned and positioned differently to form an oval-like structure. Some other facts are:

  • The cranium and facial bones are joined by Sutures
  • The bone of the upper jaw is known as Maxilla
  • The bone of the lower jaw is known as Mandible
  • The mandible is the only bone in the entire human skull that can make movements and is not static

4. Jaw Wiring Is Also Used As A Part Of The Cosmetic Treatment and Surgery. Comment On This Statement.

Sample Answer

Sir, this statement is true. The medical technique of jaw wiring was initially developed to heal a fractured bone or re-align a dislocated jaw and put it back in order. However, given the popularity of this technique, it is now also used to attain weight loss targets. By wiring the jaw voluntarily, patients nowadays can restrict their diets as the wiring discourages frequent ingestion of food.

5. Anesthesia Is Commonly Used By The Orthodontists To Treat The Patients. Can You Tell In Brief About The Four Stages Of Anesthesia?

Some of the common deficiencies caused due to the deficiency of Vitamin D are:

  • Rickets
  • Osteomalacia
  • Osteoporosis
  • Dental problems

7. Prepare A Diet Plan For The Patient Who Has Just Got The Treatment For A Teeth Irregularity. He Is Having Braces As Well. (You Might Be Given A Pen and A Paper)

Sample Answer

Sir, in situations where a patient is holding up braces and is experiencing teeth irregularity, Orthodontists recommend a soft diet for the patients. The food items in a soft diet are easily chewable and do not lay stress upon the gums and the teeth. I will recommend the following diets:

  • Boiled vegetables such as carrots, broccoli, peas, potatoes, etc.
  • Soft fruits such as kiwi, tangerines, grapefruits, etc.
  • All the types of fluids that are neither too cold nor too hot
  • Soft bread, like pancakes, tortillas, muffins, etc.

8. Bone Development Is A Consistent Process and There Are Always Some Re-modelling Processes Going On In Our Human Body. Explain This Statement Using Valid Arguments.

Sample Answer

Sir, I completely agree with this statement. In the human body, the various processes of modeling and re-modeling go on at different junctures and points in time. These processes are carried out by the different bone cells, which are:

  • Osteocytes: These are the mature bone cells and help in the maintenance of strength, resilience, and resistance capacity of the bones
  • Osteoblasts: These bone cells help in the formation of new bones
  • Osteoclasts: These bone cells help in the destruction of unwanted bones as a part of the re-modeling strategy

9. As An Orthodontist You Will Be Required To Work Upon Affixing and Tightening The Braces. What Are The Different Types Of Invisible Braces?

Sample Answer

Yes sir, The primary role of an orthodontist revolves around affixing, tightening, and even suggesting the different types of available braces. Some of the common invisible braces are:

  • Lingual bracket braces system: The braces are placed towards the inner side of the teeth. These are not visible from the outside. However, these cannot be removed without medical attention once affixed.
  • Clear aligners braces system: These are also invisible braces and are not visible from the outside. However, unlike the lingual systems, these can be removed by the patient while brushing, eating, flossing, etc. These also help in the fast treatment and are normally affixed for 15 days.

10. Medicine Is A Developing Field and There Are Always New Developments and Findings. How Do You Keep Yourself Updated?

Sample Answer

Sir, I completely agree with this statement. Not only medicine, but the entire Science is a work in progress, and there are always new developments, theories, thesis, discoveries, and findings that challenge the already established principles and conventions. Hence, a medical professional must always keep oneself abreast of all the latest developments and happenings.

I do so by reading out the medical journals and magazines that cover all the latest domestic as well as international inventions and discoveries in the field of medicine, especially in my field of dentistry.

11. What Do You Know About Diastema? How Do You Correct This Defect?

Sample Answer

Sir, a diastema is a common tooth defect in which there are large/ small gaps between the teeth. This does not let the patients properly chew food and leads to an inappropriate biting pattern. This defect is largely corrected by tightening braces in the teeth. The sustained pressure created by braces helps the teeth to come closer to each other and fill the gaps between them. It is a gradual process and the patients are required to use the braces for at least 3 weeks.

12. Assume A Situation In Which You Are Witnessing Some Unclean and Unhygienic Braces On The Teeth Of A Child. How Will You Handle The Situation and What Will You Recommend The Child?

Sample Answer

Sir, such issues are common and I have dealt with them before as well. In such a case, I will, first of all, make the child as well as his or her parents aware of the various dental problems that might develop if the child fails to clean the braces.

Post this, I will recommend the child to clean the braces and teeth using the following methods:

  • Using electric brushes
  • Using interdental brushes
  • Using floss threaders to clean the teeth and braces
  • Using revealing tablets to eliminate all the unchewed/ uningested food particles stuck in the jaw teeth
  • Usage of mouthwashes that are rich in fluoride

13. Describe A Time When You Lost Your Cool and Maltreated Your Patient Out Of Frustration.

Sample Answer

Sir, medicine is a tough profession. When you have to deal with so many patients in a single day, attend to emergencies and listen to all the patient grievances, it starts taking a toll after some time.

I remember an instance when a middle-aged man was quite skeptical about my treatment and was constantly questioning me at my every step. This irritated me then, and I yelled at him. However, I quickly realized my mistake and almost instantaneously apologized to him.

Hence, be assured that I will neither refuse nor give any excuse for not attending to the patients.

17. What Is Teeth Straightening? Is It Different From The Process of Alignment?

20. Describe Your Best and Worst Reporting Manager/ Senior/ Boss.

Sample Answer

Sir, during my college days I undertook a six-month internship with a medical center. My senior over there was quite arrogant and always discouraged me from doing new things or learning new processes.
