I chipped my bondage tooth two days before my interview. The staff was very friendly and accommodated me the SAME day (was a new patient)! My tooth looks even better than it did before it broke.

Downtown Los Angeles
Technology supports the care. It never replaces it.
Dr. Kourosh Yousefzadeh, D.D.S. leads the practice. The equipment below is what lets the team work more precisely.
Technology
The equipment behind the diagnosis
Six tools used at the Downtown office, and what each one changes about your appointment. Every item here is in service of a more precise diagnosis and a shorter visit.
01
3D Cone Beam CT
A low-radiation 3D scan of teeth, jawbone and surrounding structures, giving far more information than standard X-rays for diagnosis and implant planning.
02
iTero digital scanner
A fast, comfortable, highly accurate 3D scan of your teeth. No goopy impression trays required.
03
CAD/CAM restorations
Restorations designed and created digitally for a precise, natural-looking fit, often reducing visits and the need for messy temporaries.
04
Soft-tissue laser
Precise, comfortable gum treatment, often with less bleeding, minimal swelling and faster healing than traditional techniques.
05
Intraoral camera
A small camera that captures close-up images inside your mouth on a screen, so you can see exactly what we see.
06
Digital and panoramic X-rays
Significantly less radiation than traditional film, often up to 80 to 90 percent less, while producing sharp, instant images.
Every tool above is used in the Downtown office.

Helpful Answers
Frequently Asked Questions
Common questions about the technology we use and how it benefits your care.
What is a 3D Cone Beam CT scan?
It’s a low-radiation 3D imaging scan that captures detailed views of your teeth, jawbone, and surrounding structures — giving us far more information than standard X-rays for precise diagnosis and implant planning.
Do you use digital impressions instead of messy molds?
Yes. Our iTero digital scanner captures a fast, comfortable, highly accurate 3D scan of your teeth — no goopy impression trays required.
What is an intraoral camera?
It’s a small camera that captures close-up images inside your mouth and displays them on a screen, so you can see exactly what we see.
How does technology make my visit more comfortable?
Modern tools help us work more precisely and efficiently, which often means shorter appointments, less discomfort, and more conservative treatment that preserves your natural teeth.
Is your equipment up to date?
Yes. We invest in modern, well-maintained technology — from 3D Cone Beam CT and digital scanning to soft-tissue lasers — to deliver the best possible care.
Can you make crowns and restorations digitally?
Yes. With CAD/CAM technology we design and create restorations digitally for a precise, natural-looking fit — often reducing the number of visits and the need for messy temporaries.
What is laser dentistry?
We use soft-tissue lasers for precise, comfortable gum treatments — often with less bleeding, minimal swelling, and faster healing than traditional techniques.
Are your X-rays safe?
Yes. Our digital and panoramic X-rays use significantly less radiation than traditional film — often up to 80 to 90 percent less — while producing sharp, instant images.
How does technology improve diagnosis?
High-resolution 3D and digital imaging help us detect issues like decay, bone loss, and infection earlier and more accurately than the naked eye alone.
Will technology replace the personal attention I get from my dentist?
Never. Technology simply supports the care your dentist provides — it helps him treat you more precisely while keeping your experience personal and gentle.
