Question 1

What is a CT scan for the mouth?

Accepted Answer

A CT scan for the mouth (often a cone‑beam CT) is a 3D X‑ray that provides detailed images of teeth, jawbones, sinuses and surrounding structures. Dentists use it to plan implants, evaluate trauma, infections, impacted teeth, tumors, TMJ disorders and root‑canal anatomy. The test is noninvasive, quick, and uses ionizing radiation—cone‑beam scans typically deliver lower doses than medical CTs.

Question 2

Is a CBCT scan painful?

Accepted Answer

No, a CBCT scan is not painful. It’s a noninvasive imaging procedure where you sit or stand while the machine rotates around your head; you may feel mild discomfort from keeping still, biting a positioning device, or having your head stabilized. Some people with claustrophobia or neck pain may find it uncomfortable. The scan itself is quick and painless, with only minimal, imperceptible radiation exposure.

Question 3

What is the cost of CBCT full mouth?

Accepted Answer

Full‑mouth CBCT costs vary by country and clinic. Typical ranges: India about ₹2,000–₹7,000; UK private clinics £90–£350; US $200–$1,200 (commonly $300–$800); Australia roughly A$200–A$600. Final price depends on location, field‑of‑view, machine quality and reporting. Always confirm with the clinic for exact fees and any interpretation, follow‑up charges, and insurance coverage or referral requirements.

Question 4

Can a CT scan show dental problems?

Accepted Answer

Yes. CT scans, including cone beam CT used in dental practice, provide three dimensional images of teeth, jaws, bone loss, impacted teeth, fractures, root anatomy, infections or abscesses, and help with implant and surgical planning. They show bone and some soft tissue better than plain X rays but may miss very small cavities and involve higher radiation and cost.

Question 5

Are dental CT scans safe?

Accepted Answer

Dental CT scans are generally safe when medically justified. They expose you to more radiation than standard dental X-rays but modern cone‑beam CTs use relatively low doses and follow ALARA principles. They provide valuable 3‑D detail for implants, surgery, or complex diagnostics. Risks are minimal for most adults; avoid or postpone in pregnancy and use alternatives for children when possible.

Question 6

Why do I need a CT scan on my throat?

Accepted Answer

A CT scan of your throat gives detailed cross-sectional images to diagnose and guide treatment. It detects infections or abscesses, tumors, swollen lymph nodes, structural problems, fractures or foreign bodies, and airway narrowing. Doctors use it to stage cancers, plan biopsies or surgery, and assess the extent of disease. Contrast dye may be used to highlight blood vessels and soft tissues.

Question 7

What is a celiac profile test?

Accepted Answer

A celiac profile test is a set of blood tests used to screen for and help diagnose celiac disease. It typically includes anti-tissue transglutaminase (tTG) IgA, total serum IgA, anti-endomysial antibodies (EMA), and sometimes deamidated gliadin peptide (DGP) antibodies or HLA-DQ2/DQ8 genotyping. Accurate results require the patient to be consuming gluten; positive results often lead to intestinal biopsy for confirmation.

Question 8

What are the four markers for celiac disease?

Accepted Answer

Four key markers used to diagnose celiac disease are: tissue transglutaminase IgA (tTG‑IgA), endomysial antibody IgA (EMA‑IgA), deamidated gliadin peptide antibodies (DGP—IgA and/or IgG), and total serum IgA level (to detect IgA deficiency that can affect test accuracy). These tests are interpreted with clinical features and, if needed, duodenal biopsy or HLA‑DQ2/DQ8 typing.

Question 9

What does a positive celiac test mean?

Accepted Answer

A positive celiac blood test indicates you have antibodies suggesting an immune reaction to gluten and raises strong suspicion for celiac disease. It isn’t definitive—confirmation usually requires clinical assessment, intestinal biopsy or genetic (HLA) testing and staying on gluten until testing. Positive results warrant gastroenterology referral, assessment for nutritional deficiencies and bone health, and guidance on a strict lifelong gluten-free diet if confirmed.

Question 10

What are 5 signs and symptoms of celiac disease?

Accepted Answer

Five common signs and symptoms of celiac disease are chronic diarrhea and steatorrhea (fatty, foul‑smelling stools), abdominal pain with bloating, unintended weight loss or poor growth in children, iron‑deficiency anemia causing fatigue and pallor, and dermatitis herpetiformis — an intensely itchy, blistering skin rash often directly linked to gluten exposure.
