Discover the essential factors to consider when choosing the best intraoral x-ray sensor for your dental practice. Learn about top products and make an informed decision with our comprehensive guide.

The portable and lightweight intraoral X-ray sensors are designed to help generate crisp, digital images. Imaging procedures in your office are more productive when you use this sort of sensor because it allows dental practice staff to swiftly and conveniently collect the pictures they require for diagnostic and therapeutic purposes.

It is less complicated than conventional film X-rays, which are frequently more expensive to use, generate more waste, and are less effective or accurate than digital dental X-ray sensors.

Utilizing digital X-ray sensor technology has the advantage of speeding up image capture. It is recommended that you start with a minimum number of sensors when switching from film to digital, and add more if you discover that sensor availability is negatively affecting X-ray scheduling.

Intraoral sensors and other digital X-ray equipment have been eagerly adopted by many dental professionals in recent years. If you’re modernising your practice with the goal of drawing in new patients, having a digital radiography set-up is certainly a step in the right direction.

What is an intraoral sensor?

A digital intraoral sensor is a small device that is placed inside the mouths of patients for the purpose of capturing X-ray images. Patients will participate in a safe x-ray taking experience where they can rapidly receive a diagnosis.

Patients can stay in their exam chair while the sensor is placed, saving them from having to put on a bulky radiation protection jacket and being seated in a massive, intimidating machine – all of which is required for traditional film-based x-rays.

The sensors only need to stay in the patient’s mouth for a short period of time and have rounded edges to make them as comfortable as possible. Once finished, a computer can instantly bring up the photographs for immediate viewing. As a result, the procedure is simpler for the personnel to conduct and far more comfortable for the patient.

Choosing the right intraoral sensor: Key factors to consider

When purchasing an intraoral sensor for your dental practise, there are several important factors to consider to ensure you get the best product for your needs. It’s critical to understand the various features and specifications of the sensors on the market, from resolution and image quality to compatibility and durability. You should also consider the cost, warranty, and customer service of the company from which you are purchasing.

In this section, we will go over the most important factors to consider when selecting an intraoral sensor and assist you in making an informed decision when purchasing this vital piece of dental equipment.

Buyer’s guide to digital dental x-rays

Image quality

When purchasing an intraoral sensor for dental x-rays, image quality should be a top priority. Since the introduction of these sensors in the early 1990s, advancements in technology have led to improved image quality. However, it is important to note that not all sensors are created equal.

A key specification to consider is the visible resolution, measured in line pairs per millimeter (lp/mm), with a benchmark of 20 lp/mm or higher. It’s also important to consider if the sensor has image noise reduction features, such as an optical fibre layer, which can enhance image quality.

However, it’s important to not rely solely on specifications or manufacturer’s claims when evaluating image quality. It is recommended to request an in-office demonstration of the sensor system using your own intraoral x-ray equipment and take images of anterior and posterior teeth on the maxillary and mandibular arches, testing different exposure settings. This will allow you to see the quality of the images produced in your office and ensure that the sensor meets your expectations for image quality.

Size of the sensor

Most manufacturers make three different sizes of digital dental sensors: Size 2 sensor for adult use; size 1 for children; and size 0 is for younger kids ages 8 and below.

A size 2 sensor will be required by many dental offices, and whether or not you anticipate seeing a lot of youngsters will determine if you require a size 0 sensor. A size 0 sensor and potentially a size 1 sensor are required for paediatric offices.

Since these size sensors can differ significantly between companies, make sure to check and compare their actual dimensions. Verify the outside measurements and the image’s actual area.

Think about the number of different sizes you’ll need to accommodate the range in patient ages and sizes. Your dental assistant should have a decent notion of the sizes you require because the sensor size is comparable to the matching film size.

Interface

The interface between the computer and the sensor must be taken into account. Some feature several interfaces, such USB and Ethernet. A USB booster might also be required if the interface is USB and the sensor and computer are more than roughly 16′ apart.

Even without a cable to the computer, wireless technology is available. Before purchasing sensors, discuss the best type of interface with your computer provider or information technology professional. This will help you choose the right interface for your computer system and software.

Sensor comfort and shape

The comfort and shape of dental sensors are important because they influence the patient’s experience during the imaging process. A sensor that is uncomfortable or has an awkward shape can cause discomfort or even pain for the patient, leading to a negative experience and making accurate images difficult.

Comfortable sensors have rounded edges and a smooth surface, which reduces discomfort and irritation in the patient’s mouth. This will assist the patient in relaxing and remaining still during the imaging process, which is critical for accurate image capture.

A comfortable and well-shaped sensor will be easier for the dental assistant to place in the patient’s mouth and will be less likely to cause injury or damage to the patient’s oral tissue. This will help to reduce the risk of complications and improve overall imaging safety.

Having a comfortable and ergonomic sensor can also increase the patient’s willingness to comply with the exam and reduce the number of retakes required, saving time and improving the efficiency of the dental practise.

Sensor compatibility with existing imaging software

When a sensor is plugged into a PC that is running another imaging software, you are likely to come across a few potential situations.

The imaging software may be unable to recognise the image captured by the sensor. If the imaging software can capture the image, it may not support “capture automation” for that sensor.

The best scenario is when the software can capture the image and use the same automation capabilities as its own sensor.

If you already have imaging software on computers in your operatory and do not want to replace it, ask your software provider for a complete list of compatible X-ray sensors.

When switching from film to digital, you will have more options. When choosing an imaging application and sensor, look for software with an open architecture. This will broaden your options when the time comes to upgrade your digital system.

In addition, enquire about how the imaging software and X-ray sensor system will work with your practice management software. Also, consider the file format of the images produced by the sensor and ensure that they can be easily imported into your existing software.

You will also need to consider whether the purchase will hinder upgrading your system in the future. Does the sensor you’re considering allow you to switch between modes? Is the sensor you’re considering flexible enough to let you switch practice management or imaging software in the future without jeopardising your initial sensor investment?

Software integration can be quite technical. Involving your computer supplier, information technology specialist, distributor, and sensor manufacturer in this discussion will help to avoid many functional issues that arise when transitioning from film to digital technology or upgrading your current digital sensor system.

Warranty

A warranty serves as a guarantee that the product will function as intended and can provide peace of mind that you will be protected in case of defects or malfunctions.

Warranty terms can vary greatly among manufacturers and it’s important to carefully review the terms of the warranty before making a purchase. Some warranties may only cover certain parts of the sensor or may only be valid for a limited time period. It’s essential to understand what is covered under the warranty, the length of the warranty period, and the process for making a claim.

Additionally, it’s important to consider the reputation of the manufacturer and their track record for honouring their warranties. Some manufacturers may be more reliable than others, and it’s worth researching customer reviews and asking for recommendations from other dental professionals.

Besides providing protection against defects and malfunctions, the warranty can give confidence in the product and the manufacturer. Carefully reviewing the terms of the warranty and researching the reputation of the manufacturer can help you make an informed decision when purchasing a dental x-ray sensor.

Product reliability

The sensor is critical to the success of your dental radiography service. How reliable is the sensor? Inquire with the distributor or manufacturer about the most common sensor failure.

The cable is most likely the most common source of sensor failure. Why is this the case? Your cable can have anywhere from 4 to 16 wires depending on your sensor. Every sensor manufacturer now has different wire gauges. Some are thicker than others. The fewer wires in the cable, the larger the gauge wire used by the manufacturer.

In a typical dental office, it is estimated that a sensor bends nearly 12,000 times per year. The wires in the cable, from this repeated action, will eventually separate from one another.

The sensor and its housing are the next likely culprits for sensor failure. One of the most common causes of sensor failure is applying too much force to the sensor, which can be caused by a variety of factors. The dental sensor could have been dropped, stepped on, bitten on, crushed, or any other number of things.

Although most dental sensors on the market are now fairly resistant to these types of things, but just like a smart phone, some can take repeated falls and will not break, others get damaged at the first instance of mishandling.

Sensor holder

This is the device that holds the sensor in place during the x-ray process. The sensor holder is a crucial component of the x-ray system, as it plays a key role in ensuring accurate and consistent image capture.

The sensor holder should be designed to hold the sensor firmly in place during the x-ray process, while also allowing for easy and precise positioning. This is particularly important when taking x-rays of the posterior teeth, where small movements can lead to large inaccuracies in the final image.

It’s important to consider the design of the sensor holder, as some are more user-friendly than others. A well-designed sensor holder should be easy to use, comfortable for patients and should provide stable positioning of the sensor. Additionally, the sensor holder should be durable and able to withstand the demands of daily use in a dental practice.

Additionally, when purchasing the sensor, it’s important to consider the compatibility of the sensor holder with the sensor, some manufacturers provide a specific holder for their sensors, and using a different holder may affect the image quality.

Technical support

Understanding more about the reputation of the manufacturer is crucial whether you are about to start a digital conversion for the first time or are seeking for the newest technology to replace your current digital sensor system. Digital sensors are an expensive investment, so you need to be certain you are working with the right tech firm.

Find out how long they have been in operation. Have they demonstrated a history of digital innovation? Consult with other dentists who have tried the items of this company and look for recommendations.

It is crucial that you enquire as to how the system will be supported if something goes wrong. Be aware that not all distributors and IT firms provide a full range of services, including system integration, sensor replacement and repairs, computer hardware, software, and networking.

The company that makes the sensors does not necessarily need to supply all of these services, but there needs to be strong communication between the various players – distributor, sub-contracted IT technician or field technicians directly employed by the manufacturer – so issues can be fixed promptly.
