Question 1

“What are the key purposes of prescribing radiographs in pediatric dentistry?” ==

Answer 1

Evaluation of dentition development, pathological evaluation, detection of anomalies, and post-treatment assessment.

Question 2

“Which stages of tooth development are evaluated using radiographs?” ==

Answer 2

Stages of development, eruption, teeth exfoliation, root formation, and physiologic root resorption.

Question 3

“How do radiographs help in detecting dental caries?” ==

Answer 3

Radiographs help detect caries and evaluate the degree of pulp involvement.

Question 4

“What are radiographic signs of traumatic injuries in children?” ==

Answer 4

Radiographs can show root fractures, damage to periapical tissues, and interradicular areas.

Question 5

“What anomalies can be detected through radiographs in children?” ==

Answer 5

Detection of ankylosis, congenitally missing teeth, supernumerary teeth, and malformed teeth.

Question 6

“What is the importance of post-treatment radiographic evaluation?” ==

Answer 6

To assess the accuracy of treatment, success of pulp therapy, postsurgical healing, and failure.

Question 7

“What are the basic principles of radiation protection?” ==

Answer 7

Justification, limitation, and optimization.

Question 8

“Why are children more sensitive to radiation compared to adults?” ==

Answer 8

Children’s tissues are still growing, their lifespan is longer, and the effects of radiation are cumulative.

Question 9

“What methods protect dental staff from radiation exposure?” ==

Answer 9

Using shielding, radioprotective barriers, maintaining a 2-meter distance, and avoiding standing in the path of the beam.

Question 10

“How can you protect pediatric patients from radiation exposure?” ==

Answer 10

Use of lead aprons, thyroid collars, rectangular collimation, correct focus-to-skin distance, and faster image receptors.

Question 11

“When should you prescribe dental radiographs for pediatric patients?” ==

Answer 11

According to AAPD guidelines, based on the child’s clinical situation and individual risk factors.

Question 12

“What is the indication for intraoral periapical (IOPA) radiographs?” ==

Answer 12

To evaluate root development, periapical tissue, and developmental abnormalities such as supernumerary teeth.

Question 13

“What are the two common techniques used for IOPA radiographs?” ==

Answer 13

Paralleling technique and bisecting angle technique.

Question 14

“What is the key benefit of the paralleling technique in IOPA radiographs?” ==

Answer 14

It produces accurate and reproducible images with minimal distortion.

Question 15

“What is the main purpose of intraoral bitewing (IOBW) radiographs?” ==

Answer 15

Detection of incipient caries, assessment of interproximal bone height, and detection of ankylosed teeth.

Question 16

“What are occlusal radiographs used for?” ==

Answer 16

To identify the bucco-lingual position of teeth, assess impacted canines, and view trauma-related issues.

Question 17

“What are the main indications for panoramic radiographs in children?” ==

Answer 17

To assess large areas of the maxilla and mandible, view the TMJ, and reduce repeated exposures.

Question 18

“Why is cephalometric imaging commonly used in pediatric dentistry?” ==

Answer 18

It is used for orthodontic assessment and planning in cases of skeletal discrepancies and growth analysis.

Question 19

“What are the key indications for using Cone Beam CT (CBCT)?” ==

Answer 19

Localization of impacted teeth, assessing periapical pathosis, and planning for orthognathic surgery.

Question 20

“Why is ultrasound imaging advantageous in pediatric dentistry?” ==

Answer 20

It is useful for examining soft tissues, such as the floor of the mouth and salivary glands, without radiation exposure.

Question 21

“What is the primary use of MRI in pediatric dental imaging?” ==

Answer 21

It is used to assess soft tissues, especially in TMJ disorders.

Question 22

“What techniques help manage pediatric patients during radiographs?” ==

Answer 22

Tell-Show-Do, using film holders, modifying the technique for gag reflex, and using extraoral radiographs when needed.

Question 23

“How do you manage gag reflex in children during radiographic procedures?” ==

Answer 23

Avoid sliding the film along the palate, use distraction techniques, salt on tongue tip, or topical anesthetics.

Question 24

“What techniques help children with special needs during radiographs?” ==

Answer 24

Use of film holding devices, extraoral techniques, or general anesthesia if necessary.

Question 25

“What is the ALARA principle?” ==

Answer 25

As Low As Reasonably Achievable: minimizing radiation exposure while obtaining diagnostic images.

Question 26

“How does rectangular collimation reduce radiation exposure?” ==

Answer 26

It limits the irradiated area and reduces radiation dose by up to 50% compared to circular collimators.

Question 27

“What is the recommended focus-to-skin distance for pediatric radiographs?” ==

Answer 27

A minimum of 20 cm to reduce radiation exposure to the patient.

Question 28

“Which film size is recommended for bitewing radiographs in small children?” ==

Answer 28

Size 0 film is used for bitewing and IOPA radiographs in small children.

Question 29

“What is the vertical angulation for IOPA radiographs of maxillary anterior teeth?” ==

Answer 29

ERROR!

Question 30

“What is the main concern with using medical CT scans in pediatric patients?” ==

Answer 30

It delivers high radiation doses and should be reserved for cases like tumors or malignancies.
