Dental radiology is the foundation of every modern diagnosis and every well-founded treatment plan. At BUTE DENTALL CLINIC in Bucharest and at DENTALL M in Râmnicu Sărat, digital imaging investigations — from simple X-rays to 3D tomography — are performed with state-of-the-art equipment, minimal radiation doses, and results available immediately on screen, in the dentist's office.
What is dental radiology and when do you need it
The human eye, however experienced the dentist, cannot see through tissues. Cavities forming between teeth, bone changes beneath the gum line, the state of the roots of a problematic tooth, the fine canals of a molar, or the relationship between tooth roots and the maxillary sinuses — all of these remain invisible at a simple clinical examination. Dental radiology gives the dentist exactly what is missing: a precise image of what is happening inside the teeth, the jawbones, and the surrounding structures.
Moreover, radiology is not only a diagnostic tool. It underlies the planning of any complex treatment: before placing a dental implant, the dentist must know exactly how much bone mass exists and where the critical anatomical structures are. Before a root canal, the exact number of canals and their anatomy must be known. Before orthodontic treatment, the bone structure, roots, and impacted teeth must be evaluated. Without imaging, these decisions would be made partially in the dark — with unnecessary risks and uncertain outcomes.
An imaging investigation may be recommended at the first consultation, at routine periodic check-ups, before any major surgical or restorative procedure, or when the patient reports pain or discomfort without an obvious cause at clinical examination. Sometimes a simple X-ray taken during a scaling appointment reveals an interproximal cavity — one forming exactly between two teeth, where neither the brush nor dental floss reaches and where a visual examination cannot detect it.
Who is dental radiology recommended for
Adult patients at periodic check-ups
At each routine check-up, the dentist evaluates whether an additional X-ray is needed beyond previous investigations. This decision depends on the patient's history, individual risk of decay, any existing prosthetic restorations, and the time elapsed since the last investigation. Periodic X-rays are not taken "as a matter of routine" — they are taken when they provide information that cannot be obtained any other way.
Patients undergoing implant treatment
Dental implant placement is a precision surgical procedure. Before placing any implant, the dentist needs an exact three-dimensional image of the available bone, the location of nerves, the proximity of the maxillary sinuses, and bone density. Cone beam computed tomography (CBCT 3D) is mandatory at this stage — it makes the difference between an implant placed with maximum safety and one that might generate unforeseen complications.
Patients with pain or unclear symptoms
Dental pain has multiple and not always obvious sources. A diffuse ache around a group of teeth may be caused by deep decay, an invisible fracture, an abscess at the root tip, or a problem at the temporomandibular joint. X-rays allow the systematic exclusion of causes and guide the diagnosis toward the real source of the problem.
Children and adolescents in growth
In young patients, a panoramic X-ray provides an overview of the developing dentition: wisdom teeth not yet erupted, permanent teeth that have not emerged on time, any impacted or supernumerary teeth. This information is essential for correctly directing orthodontic treatment and preventing more serious problems in adulthood.
Patients before orthodontic treatment
Before applying fixed or removable dental appliances, the orthodontist needs a complete evaluation of bone structure, root length, the relationship between teeth and bone, and the degree of jaw growth. This information is obtained by combining a panoramic X-ray with a lateral cephalometric radiograph — an image specific to orthodontics that allows cephalometric analysis.
Patients with a problematic wisdom tooth
The wisdom tooth (the third molar) is, from an imaging standpoint, one of the most demanding teeth. It may be partially or fully impacted in bone, angled in various directions, and in close proximity to the inferior alveolar nerve — an important anatomical structure that must be protected during any surgical procedure. A panoramic X-ray, sometimes supplemented by CBCT, is mandatory before extracting a complicated wisdom tooth.
Types of imaging investigations available
Digital periapical X-ray (RVG)
Digital periapical radiography — commonly referred to by the acronym RVG (radiovisography) — is the most frequently used imaging investigation in the dental office. It provides a highly detailed image of one or a few adjacent teeth: the root, periodontal space, surrounding alveolar bone, and root apex. It is essential for diagnosing decay, monitoring root canal treatments, evaluating root resorption, and verifying prosthetic restorations.
The digital RVG system has clear advantages over conventional film radiography: the radiation dose is up to 80% lower, the image appears on screen within seconds, it can be magnified, contrast-adjusted, and analyzed directly, and archiving is immediate and secure. At BUTE DENTALL CLINIC and DENTALL M, RVG is integrated into the digital workflow of the office, meaning the dentist can analyze the image and explain findings to the patient during the consultation itself.
Panoramic X-ray (OPG / Orthopantomography)
The panoramic X-ray — also known as OPG or orthopantomography — provides a single overview image of the entire oral cavity: all teeth, both jaws, the temporomandibular joints, maxillary sinuses, and mandibular canals. It is the ideal investigation for a global assessment of dental status, for planning complex treatments, or for the initial evaluation of a new patient.
An OPG is frequently recommended before orthodontic treatment, before complicated extractions, in the evaluation of children and adolescents, and for long-term treatment monitoring. The image is obtained quickly, without discomfort for the patient, and the radiation dose is comparable to that of a few periapical X-rays.
A panoramic X-ray is not taken "once and done" — it has a period of informational validity that depends on the complexity of the situation and the rate at which the dental condition evolves. A patient with a stable situation may rely on the same panoramic X-ray for longer; one in active treatment will require periodic updates.
Cone beam computed tomography (CBCT 3D)
CBCT (Cone Beam Computed Tomography) is the three-dimensional imaging investigation with the greatest clinical relevance in modern dentistry. Unlike panoramic or periapical X-rays, which provide two-dimensional images, CBCT generates a volume of data from which the dentist can extract cross-sections in any plane — frontal, lateral, axial — and evaluate anatomical structures with remarkable precision.
The main clinical uses of CBCT include implant planning (volume, density, and direction of available bone; relationship with nerves and sinuses), diagnosis of root fractures invisible on 2D X-rays, evaluation of impacted wisdom teeth, analysis of canal anatomy before complex endodontic treatments, planning of orthognathic surgery, and evaluation of cystic or tumoral lesions in the jawbones.
The CBCT available at DentALL clinics allows selectable examination volumes — from a small field (a few teeth) to a large field (the entire face) — enabling radiation dose to be adapted to the clinically necessary information. The principle is simple: exactly as much as needed is used, no more.
Bitewing X-ray (interproximal)
The bitewing X-ray is a specialized imaging technique for detecting interproximal cavities — those forming on the contact surfaces between teeth. The patient gently bites on a small positioning device, and the X-ray simultaneously captures the crown of both upper and lower teeth, with an excellent image of the contact areas. It is recommended especially for children and adults at high risk of decay, as part of the periodic dental assessment.
How an imaging investigation is carried out, step by step
The procedure for taking a dental X-ray is quick, painless, and requires no special preparation from the patient. Here is how it unfolds, depending on the type of investigation.
For a periapical RVG X-ray, the technician or dentist positions a small digital sensor inside the patient's mouth, beside the tooth or teeth of interest. The patient is asked to close the jaw gently to hold the sensor in place, or to press lightly with a finger. The X-ray device is positioned outside the mouth at a standardized distance. The exposure lasts a fraction of a second, and the image appears on the in-room screen within seconds.
For a panoramic OPG X-ray, the patient stands or sits with the chin resting on a support and the teeth lightly biting a positioning guide. The X-ray device rotates around the head, capturing the overall image. The procedure takes approximately 15–20 seconds and involves no intrusive contact.
For CBCT 3D, the patient is positioned similarly to the OPG, with the head gently stabilized. The device performs a rotation around the head, capturing hundreds of images that are reconstructed three-dimensionally by software. The entire acquisition takes a few seconds to a minute, and the 3D image is available immediately after processing is complete.
In all cases, the result is available digitally immediately, with no waiting time for development. The dentist can analyze the image directly on the in-room screen, explain findings to the patient, and make informed clinical decisions within the same consultation.
Safety in dental radiology: low doses, high information
Fear of radiation is one of the most common reservations patients express before a dental X-ray. This concern is understandable, but — in the context of modern digital dental imaging — is, for the most part, disproportionate to the actual risk.
A few useful perspectives: a digital periapical X-ray (RVG) involves a radiation dose comparable to the natural cosmic radiation we receive during a few hours of flight at altitude. A panoramic X-ray is equivalent to a few days of exposure to the natural background radiation at ground level. Even a medium-volume CBCT represents a dose far smaller than a conventional medical computed tomography (CT) scan of the body.
All of modern dentistry operates on the principle of ALARA — an acronym for As Low As Reasonably Achievable. This means that no imaging investigation is prescribed routinely, but only when the clinical benefit of the information obtained outweighs the minimal risk of exposure.
Digital radiology systems significantly reduce the dose compared to conventional film radiography — by up to 60–80% in the case of RVG, and by significant percentages for digital OPG as well. Modern CBCT devices allow selection of exactly the field volume needed, reducing exposure to structures that are not of clinical interest.
Protective equipment — lead aprons, thyroid collars, and other specific devices — complements dose reduction measures, especially for groups with increased sensitivity.
Safety in pregnancy and for children
Pregnant women are a special category: dental X-rays are avoided where possible, especially in the first trimester. When they are absolutely necessary (for example, in the event of a dental emergency), additional protective measures are taken and the type of investigation is chosen to minimize abdominal exposure. The dentist must always be informed of an existing or possible pregnancy.
For children, radiation doses are calculated in relation to body weight and the greater sensitivity of growing tissues. X-rays are prescribed only when clinically justified, and the equipment used at DentALL allows adjustment of exposure parameters according to the patient's age and size.
Common myths about dental radiology
"Dental X-rays are dangerous and emit a lot of radiation"
This misconception is among the most widespread. The clinical reality is otherwise: the radiation dose received from a digital periapical X-ray is negligible relative to the natural background radiation to which we are all exposed daily — from the cosmos, from the ground, from the food we consume. Fear of dental radiation is, in most cases, greater than the actual risk. Far riskier is not taking a necessary X-ray and remaining with an incomplete or incorrect diagnosis.
"I don't need an X-ray if nothing hurts"
Pain generally appears late in the progression of dental diseases. A cavity can progress for months or years without causing pain, until it reaches the nerve. An infection at the root tip can be completely asymptomatic and can be discovered incidentally on a routine X-ray. The absence of pain is not equivalent to the absence of a problem — it is sometimes a sign that the disease is progressing silently toward more serious complications.
"One panoramic X-ray is sufficient for everything and forever"
The panoramic X-ray is an excellent overview investigation, but it has its limits: resolution at individual tooth level is lower than RVG, it cannot show 3D cross-sections, and the information it provides is valid at the moment it was taken. An old panoramic X-ray does not reflect a dental situation that has changed in the meantime. Moreover, for certain clinical situations — precise diagnosis of a root canal treatment, implant planning — a panoramic X-ray is not sufficient and must be supplemented with other investigations.
"If I've had an X-ray recently, I don't need another one"
The interval between investigations depends on the individual clinical situation, not on a fixed calendar. A patient in active treatment may need multiple X-rays in a short interval, each with a specific purpose. The decision belongs to the dentist, who constantly weighs the relationship between the necessary clinical information and radiation exposure.
Cost and what influences the price
The cost of a dental imaging investigation varies depending on several factors that are important to know before booking.
The most important factor is the type of investigation: a periapical RVG X-ray is naturally more affordable than a panoramic X-ray, which in turn is more affordable than a CBCT 3D tomography. This scale reflects the complexity of the equipment used, the volume of data processed, and the dentist's analysis time.
The difference between 2D and 3D imaging is another relevant factor. The panoramic X-ray and RVG are two-dimensional investigations, faster and more affordable. CBCT is three-dimensional, provides far more clinical information, and involves considerably more complex equipment and software infrastructure.
The field volume chosen for CBCT also influences cost: a small volume (a few localized dental sections) is more affordable than a medium or large volume (the entire arch or both jaws). The dentist will always recommend the minimum volume necessary to obtain the desired clinical information — both to limit radiation exposure and to optimize the cost of the investigation.
Not least, imaging interpretation — detailed analysis of images by the dentist, with a written report or direct explanations for the patient — is an integral part of the radiology service offered at DentALL. An imaging investigation without competent interpretation has no real clinical value.
Why choose DentALL for imaging investigations
At BUTE DENTALL CLINIC in Bucharest and at DENTALL M in Râmnicu Sărat, dental radiology is not a mere formality — it is a pillar of quality diagnosis and the safety of every treatment. Investment in state-of-the-art imaging equipment reflects a commitment to precision and to the patient experience.
The digital radiology systems with reduced dose used in both clinics allow high-resolution images to be obtained with minimal exposure. Digital RVG sensors, state-of-the-art OPG devices, and a 3D CBCT scanner form a complete set of imaging solutions, all integrated into the digital workflow of the office.
The entire DentALL group operates with identical protocols at both locations — which means a patient who undergoes investigations in Bucharest and continues treatment in Râmnicu Sărat (or vice versa) benefits from the same diagnostic quality and the same interpretation standards. The patient's digital file, including radiological images, is accessible and managed coherently across both locations.
The 14 specialists of the DentALL group work in coordination, which means that a CBCT image taken for implant planning can be analyzed simultaneously by the implantologist placing the implant, the dentist performing the prosthetic restoration, and, if necessary, the oral surgery specialist. This multidisciplinary approach is possible precisely because of the digital imaging infrastructure and integrated electronic records.
The experience accumulated over many years of activity and the over 10,000 patients treated within the group have consolidated the clinical protocols and reference images, allowing comparison of changes over time and rapid identification of differences from previous investigations.
Not least, investment in traceable sterilization cycles and certified equipment ensures that all components the patient comes into contact with — including RVG sensors or positioning devices — meet the strictest hygiene standards.
Conclusion: dental imaging — a small step for the patient, a major impact on your health
A dental X-ray takes a few seconds. Sometimes those few seconds completely change the course of treatment: they reveal a cavity nobody suspected, confirm that an implant can be placed safely, or show that a root canal treatment was fully successful. At other times, they reassure an anxious patient that everything is fine.
Modern digital dental radiology is safe, fast, painless, and highly informative. At DentALL, it is part of an integrated care system in which every clinical decision is based on real data, not on estimates.
