The Dental Mirror is a relatively common medical device in dental examinations. It is mainly used to magnify the internal conditions of the oral cavity or reflect light, helping to observe the blind spots in the oral cavity. This is mainly the common oral endoscope; Another type of oral endoscope equipped with a micro camera can better reflect the internal conditions of the oral cavity on the magnifying screen display, ensuring a clear field of view and facilitating observation and operation.

 

Today, let's take a look at the usage methods and gain a deeper understanding of the features and habits of oral endoscopes.

 

Classification

 

Orthodontic Mirrors

Oral endoscopes can be classified into several major categories based on their materials, such as common metal oral endoscopes, disposable plastic oral endoscopes, and modern electronic oral endoscopes. The materials used are different, and so are the functions.

The main material of the common metal mouth mirror is stainless steel. The mirror surface can be flexibly rotated and folded. It needs to be disinfected at high temperature when in use. It mainly utilizes the reflected light source to pull the soft tissue and briefly observe the main structure of the teeth.

Disposable plastic oral endoscopes are mainly used to prevent infectious diseases, in emergency situations, and to avoid cross-infection and other situations.

The electronic oral endoscope is equipped with a high-definition camera inside, LED lighting, which can be magnified and connected to a display screen. It can take photos and videos. It is a new type of oral endoscope upgraded from modern advanced technology, which can more accurately capture the internal environment that needs to be observed and is more convenient to explain this part of the content to the patient during the examination.

Specific usage

 

The Use of Ordinary Metal Oral Endoscopes

 

The common metal oral endoscope mainly consists of several parts such as the handle, the mirror rod, the reflective mirror surface, and the probe. When operating, it is necessary to cooperate with lighting. Through reflection, the field of view that needs to be inspected is reflected to observe whether there are dental caries, tartar, food impaction, gum inflammation or oral lesions

 

The main usage steps are as follows:

1.Before use check the oral lighting lamp to reflect the light onto the area of the teeth that need to be examined.


2. Ensure that the oral endoscope and other items are sterilized at high temperatures, then proceed with the following steps.


3. Adjust the lens reflection to an appropriate Angle, observe the Angle that needs to be examined, confirm the specific position, and then reflect the image of the tooth into the dentist's eyes. Receive the relevant observation and organize the specific situation.


4. Move the oral endoscope to observe the specific conditions around the teeth in the mouth, especially paying attention to the interproximal surfaces (gaps between teeth) and the edge of the gums.


5. By using the reflection image of the inner diameter of the oral cavity, gently slide the tip of the probe into the gingival sulcus to determine if there is inflammation, tartar, food impaction.


6. After checking the content of this area, check the other area in reverse and follow the same steps to observe if there is the same situation.

Precautions

Orthodontic Mirrors

1. Keeping clean mainly refers to removing disposable oral endoscopes and related tools from disposable disinfection bags.


2. Preheating the mirror surface to prevent fogging means placing the mirror surface in warm water and preheating it for about 10 seconds to reduce fogging and keep the mirror surface clear.


3. Rinse the mirror surface with warm water for about 10 seconds to preheat it, which can reduce fogging and keep the mirror surface clear.


4. Place the oral endoscope inside the mouth, align it with the area of the teeth to be examined, and use the side light source to clearly see the details of the tooth surface, effectively observing detailed conditions such as tooth decay.


5. In conjunction with the light source, display the observation conditions inside the oral cavity through the mobile phone and observation devices, and carefully examine each surface of the teeth, such as the occlusal surface, labial and buccal surface, and interproximal surface, etc., for detailed conditions.


6.After the examination is completed, gently remove the oral endoscope for one-time centralized treatment and place it in the recycling area.
