Periapical X-rays Pa
Periapical X-rays PA is a specialized dental service provided by the board-certified specialists at Aloha Dental Specialty Center in Beaverton, OR. A focused view from crown to root tip — the diagnostic standard for single-tooth problems.
When You Need a Close-Up Look at One Tooth
A periapical X-ray — often called a PA — captures a single tooth or a small group of teeth from the biting edge of the crown all the way down to the bone beyond the root tip. It is the most commonly taken dental radiograph and the first-line diagnostic tool for toothache investigation, abscess evaluation, root canal planning, fracture assessment, and post-treatment follow-up. The sensor sits inside your mouth directly behind the tooth, and the exposure takes less than one second.
At ADSC, periapical films are taken with digital sensors that deliver the lowest practical radiation dose while producing high-resolution images displayed on the screen within seconds. The paralleling technique — positioning the sensor parallel to the tooth and directing the beam perpendicular to both — minimizes distortion and produces an image that represents the tooth close to its actual proportions. This geometric accuracy matters when measuring root length, assessing periapical lesion size, or evaluating the fit of an existing root canal fill.
Dr. Ostovar and Dr. Gvozden use periapical radiographs throughout treatment — before, during, and after procedures. A pre-operative PA confirms the diagnosis. A working-length PA during a root canal verifies that instruments reach the correct depth. A post-operative PA confirms that the root canal fill extends to the apex without overfilling. For implant follow-up, periapical films monitor crestal bone levels around the fixture over time. The periapical X-ray is simple, fast, low-dose, and indispensable.

For out-of-pocket costs, we partner with CareCredit and Cherry for flexible payment plans. We also offer our ADSC Dental Savings Plan for patients without insurance.
Most patients complete their periapical x-rays pa appointment in 45-90 minutes. Complex cases may require 1-2 hours. Your initial consultation takes about 60 minutes including imaging and treatment planning.
Recovery & Healing Timeline
Understanding the healing process helps you plan ahead and follow post-operative instructions for the best possible outcome.
First 48 Hours
Mild swelling and tenderness are normal. Apply ice packs in 20-minute intervals and take prescribed or over-the-counter anti-inflammatory medication. Eat soft foods and avoid the surgical site when chewing.
Days 3 to 7
Swelling peaks around day three and then improves. The tissue begins closing over the surgical site. Continue with soft foods and use any prescribed antimicrobial rinse. Most patients return to normal activities during this phase.
Long-Term Healing
Surface tissue heals within two to three weeks. Bone integration and deep healing continue for three to six months. Avoid smoking, follow up as scheduled, and maintain good oral hygiene throughout recovery.
Questions during recovery? Call us at (503) 822-0096. We are available for post-operative concerns.
Periapical Radiographic Technique and Diagnostic Value
The periapical radiograph has been a diagnostic mainstay since the earliest days of dental radiology, and its utility has only increased with digital technology. Modern CMOS sensors capture images at 20 or more line pairs per millimeter — sufficient resolution to detect early enamel demineralization, periapical radiolucencies as small as 1 millimeter in diameter, and root canal obturation voids. The paralleling technique, standardized in the 1950s, produces images with less than 5 percent magnification error when executed correctly. For endodontic diagnosis, the periapical film remains the primary imaging modality, supplemented by CBCT only when the two-dimensional view is insufficient to answer the clinical question.
Why Choose a Specialist?
Periapical imaging at ADSC is performed using current-generation digital sensors with automatic exposure optimization, ensuring diagnostic quality at the lowest achievable dose. Every image is reviewed by the treating specialist — Dr. Ostovar or Dr. Gvozden — not by an assistant providing a preliminary read. When a periapical film raises questions that require three-dimensional evaluation, the CBCT scanner is steps away in the same clinical suite.
Treatment time varies by complexity. A straightforward procedure may take 30-60 minutes, while more involved cases can take 1-2 hours. Your consultation visit typically lasts 45-60 minutes including imaging and treatment planning. We’ll give you a specific time estimate for your individual case.

A Note from Your Dental Team
In my experience, the patients who get the best results from periapical x-rays pa are those who come in with realistic expectations and follow their post-treatment instructions carefully. I’d rather spend extra time explaining what to expect than have a patient be surprised later.
“Every patient I see has a different story, a different set of concerns, and a different definition of what ‘success’ looks like. That’s why I don’t believe in one-size-fits-all treatment plans. When you come in for a consultation, I’ll listen first, examine second, and recommend third.
I also won’t recommend a procedure you don’t need. If your tooth can be saved with a filling instead of a crown, I’ll tell you that. If watchful waiting is appropriate, I’ll explain why. My job isn’t to sell treatment — it’s to give you my honest clinical judgment so you can make an informed decision.
If you have questions about whether this treatment is right for you, or if you’ve been told you need this procedure by another dentist and want a second opinion, call us at (503) 822-0096. We’re happy to take the time to explain everything — no rush, no pressure.”

I know many patients feel anxious about dental procedures — you’re not alone in that. What I hear most often after treatment is: “That was so much easier than I expected.” We’re here to make this as comfortable as possible for you.
Who is a good candidate? Most patients in good general health qualify for periapical x-rays pa. We evaluate your specific situation — including medical history, current medications, and dental condition — during a thorough consultation with CBCT 3D imaging. Factors like uncontrolled diabetes, certain medications, or active infections may require management before proceeding.
What are the risks? As with any dental procedure, potential risks include temporary discomfort, minor swelling, and in rare cases, infection. Serious complications are uncommon when treatment is performed by experienced specialists using proper protocols. We use 3D imaging and sterile technique to minimize risk, and we discuss all potential outcomes with you before starting treatment.

Frequently Asked Questions
What can a periapical X-ray diagnose?
Periapical radiographs diagnose cavities, periapical infection (abscess), root fractures, root resorption, bone loss around teeth or implants, the status of root canal treatment, cysts at the root tip, and the relationship of tooth roots to surrounding anatomy.
How much radiation does a periapical X-ray deliver?
A single digital periapical X-ray delivers approximately 5 microsieverts — less than one day of natural background radiation. You would need approximately 10,000 periapical films to reach the annual radiation exposure limit for the general public.
Is the sensor uncomfortable when placed in my mouth?
The sensor is a small rigid rectangle, roughly the size of a postage stamp. Most patients tolerate it easily. Placing it in the floor of the mouth behind lower front teeth can be slightly uncomfortable for some people due to the tongue and tissue. Bite blocks and positioning holders are used to improve comfort and stabilize the sensor.
Why does the dentist leave the room during the X-ray?
Although a single periapical exposure delivers a negligible dose, dental staff take hundreds or thousands of X-rays per year. Cumulative occupational exposure is minimized by stepping behind a shield or leaving the immediate area during each exposure. The patient receives only the dose from that one image.
How many periapical X-rays might I need at one visit?
It depends on the clinical situation. A single toothache investigation may require 1 to 2 periapical films. A root canal procedure involves 3 to 4 films (pre-operative, working length, master cone, and post-obturation). A periodontal assessment may use periapicals of several teeth in addition to bitewings.
Can a periapical X-ray show an infection?
Yes. A periapical abscess appears as a dark (radiolucent) area at the root tip where bone has been destroyed by the infection. The size and borders of this area help determine whether the tooth can be treated with a root canal or whether extraction is necessary.
What is the difference between a periapical X-ray and a CBCT scan?
A periapical X-ray is a two-dimensional image of one tooth, taken in seconds with minimal radiation. A CBCT scan is a three-dimensional volume of a larger area. Periapical films are used for routine diagnosis; CBCT is used when the two-dimensional view is ambiguous — such as searching for a missed canal, a fracture, or a lesion obscured by overlapping structures.
Can periapical X-rays monitor bone levels around implants?
Yes. Serial periapical films taken at placement, one year, and subsequent intervals show crestal bone levels around the implant threads. Stable bone levels indicate healthy integration. Progressive bone loss suggests peri-implantitis and prompts intervention.
Do I need a periapical X-ray if I just had a panoramic film?
Often yes. The panoramic provides an overview but lacks the resolution needed to diagnose small cavities, subtle periapical changes, or fine root fractures. A periapical film of the specific tooth in question provides the detail the panoramic cannot.
Are periapical X-rays safe during pregnancy?
The dose from a dental periapical X-ray is extremely low — about 5 microsieverts — and the beam is directed at the jaw, far from the abdomen. A lead apron provides additional shielding. The American College of Obstetricians and Gynecologists considers necessary dental X-rays safe during pregnancy. However, elective imaging is typically deferred until after delivery.
How quickly do I get periapical X-ray results?
Instantly. The digital image appears on the monitor within one to two seconds of the exposure. The doctor reviews it with you immediately.
Can a periapical X-ray find a crack in my tooth?
Some root fractures appear as a line through the root on a periapical film, sometimes with associated bone loss along the fracture plane. However, many cracks — especially those limited to the crown or that run in the buccal-lingual direction — are not visible on two-dimensional imaging and may require CBCT or direct visual inspection under magnification.
Why does the dentist take an X-ray during a root canal procedure?
Working-length radiographs verify that endodontic instruments have reached the correct depth within the canal — extending to the root apex without passing beyond it. A master cone film confirms the fit of the filling material before permanent obturation. A final film documents the completed treatment. These intra-operative films are essential for root canal quality and safety.
Does insurance cover periapical X-rays?
Yes. Periapical radiographs are covered by virtually all dental insurance plans as a diagnostic procedure, typically at 80 to 100 percent. Frequency limitations vary — some plans cover unlimited periapicals per year while others cap the number. The ADSC billing team verifies your specific coverage.
Can periapical X-rays detect cavities between teeth?
Periapical films can show interproximal cavities, but bitewing X-rays are specifically designed and angled for this purpose and are more sensitive for early interproximal decay detection. The two film types are complementary: bitewings for cavity detection, periapicals for root and periapical evaluation.
