Description

Technical Field

[0001] This utility model belongs to the field of dental instruments, and more specifically, to a device for applying anti-caries ointment. Background Technology

[0002] Dental caries, commonly known as cavities or tooth decay, is a bacterial disease. It occurs when bacteria in the mouth react with food debris to produce acidic substances. Over time, these acids act on the tooth surface, forming cavities, especially on the occlusal surfaces, eventually leading to the complete destruction and loss of the tooth crown. It can lead to secondary pulpitis and periapical periodontitis, and even inflammation of the alveolar bone and jawbone. Untreated cavities will not heal on their own, and their ultimate result is tooth loss.

[0003] Therefore, preventing tooth decay is of paramount importance. Currently, there are two main ways to prevent tooth decay: one is to pay attention to diet and maintain oral hygiene, and the other is to regularly apply anti-caries medications, such as fluoride gel. The application method involves the patient applying the ointment to the surface of the decayed tooth (i.e., cavities), keeping it in the mouth for 2-3 minutes, and then rinsing with water. However, because the surface of decayed teeth is irregular and concave, it is impossible to accurately apply the ointment to the inside of the tooth. Furthermore, the ointment comes into contact with saliva while remaining on the tooth, which may lead to accidental ingestion. Swallowing fluoride may pose certain health risks. In addition, the contact between the ointment and saliva also results in insufficient retention of the ointment on the teeth. Therefore, a new technology is needed to improve this situation. Utility Model Content

[0004] To address the problems in the prior art, this invention provides a tooth decay prevention ointment application device that can accurately apply the ointment to the surface of decayed teeth, and isolates saliva during the ointment's residence time to avoid accidental ingestion of the ointment and insufficient ointment retention.

[0005] This utility model is implemented through the following technical solution: a tooth decay prevention ointment application device, including a groove, the groove being arranged horizontally, the groove having an arc-shaped profile in cross-section, limiting members being provided at both ends of the groove, the outer edge of the limiting member coinciding with the middle of the outer edge of the arc-shaped profile, the inner wall of the limiting member being located inside the middle of the inner profile of the arc-shaped profile, a sponge being filled in the area enclosed by the inner sides of two adjacent limiting members and the inner wall of the groove, the sponge being arranged vertically, the lower end of the sponge being located below the groove, the lower end of the sponge being a pointed tip, a connector being provided on one side of the outer surface of the groove, the connector having an arc-shaped profile, the arc-shaped profile being arranged horizontally and longitudinally, an extension being connected to the end of the connector, the extension being arranged longitudinally;

[0006] In use, the sponge is in a compressed state, and the tip is pressed tightly against the outer surface of the target carious tooth in a compressed posture. The inner wall of the groove is in close contact with the inner side, outer side and occlusal surface of the target carious tooth through the sponge in a compressed posture. The inner side of the limiting member is in close contact with the upper end of the adjacent surface of the target carious tooth through the sponge in a compressed posture.

[0007] Furthermore, the sponge body is made of polyurethane foam material, and the sponge body is detachable.

[0008] Furthermore, the arc-shaped contour is an inverted U-shaped contour, and the groove thickness is 1mm to 2mm.

[0009] Furthermore, the pore size of the sponge is 85um to 95um.

[0010] Furthermore, in use, the end of the extension extends to the outer side of the oral cavity through the middle of the upper and lower central incisors.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-4As shown, an anti-caries ointment application device includes a groove 3 arranged laterally with an arc-shaped cross-section. Limiting members 3a are provided at both ends of the groove 3. The outer edge of the limiting member 3a coincides with the middle of the outer edge of the arc-shaped contour. The inner wall of the limiting member 3a is located inside the middle of the inner contour of the arc-shaped contour. This arrangement allows the inner surface of the limiting member 3a to precisely fit against the adjacent surface of the target carious tooth 5, thus completely enveloping the target carious tooth 5. The ointment applied to the sponge 4 avoids contact with oral saliva, thus isolating saliva and preventing accidental ingestion of the medication. The amount of medication remaining on the surface of the target carious tooth 5 is insufficient.

[0020] In this embodiment, the area enclosed by the inner sides of the two adjacent limiting members 3a and the inner wall of the groove 3 is filled with a sponge 4. The sponge 4 is arranged vertically, and the lower end of the sponge 4 is located below the groove 3. The lower end of the sponge 4 is a pointed tip. Since the target carious tooth 5 is generally an irregular concave surface, the pointed tip setting allows the lower end of the sponge 4 to penetrate deep into the surface of the target carious tooth 5 during use, so as to accurately cover and apply the medicine.

[0021] In this embodiment, a connector 2 is provided on one side of the outer surface of the groove 3. The connector 2 has an arc profile and is arranged horizontally and longitudinally. An extension 1 is connected to the end of the connector 2. The extension 1 is arranged longitudinally. In the biting state, it can increase the tightness of contact between the target carious tooth 5, the sponge 4, the groove 3 and the fiber. In the pressure state, it can further prevent the ointment from mixing with saliva during the application of ointment, thereby isolating saliva.

[0022] In this embodiment, in use, the sponge 4 is in a compressed state, and the tip is pressed tightly against the outer surface of the target carious tooth 5 in a compressed posture. The inner wall of the groove 3 is tightly fitted with the inner side, outer side and occlusal surface of the target carious tooth 5 through the sponge 4 in a compressed posture. The inner side of the limiting member 3a is tightly fitted with the upper end of the adjacent surface of the target carious tooth 5 through the sponge 4 in a compressed posture.

[0023] In this embodiment, the tip of the sponge 4 penetrates deep into the inner surface of the target carious tooth 5 and adheres tightly to the inner surface of the target carious tooth 5. Together with the inner surface of the limiting member 3a and the side wall of the groove 3, it surrounds the outer surface of the target carious tooth 5, so that saliva can be isolated during the ointment's stay, avoiding the problem of accidental ingestion of the ointment and insufficient ointment stay.

[0024] In this embodiment, the sponge 4 is made of polyurethane sponge material, which has good deformability and resilience. The sponge is detachable for easy replacement. The arc-shaped contour is an inverted U-shaped contour, which is suitable for applying medicine to the target carious tooth 5 in the lower groove. The thickness of the groove 3 is 1mm to 2mm.

[0025] In this embodiment, the pore size of the sponge 4 is 85um to 95um. This setting allows the sponge 4 to allow for rapid penetration and release of drugs. In use, the end of the extension 1 extends to the outside of the oral cavity through the middle of the upper and lower central incisors.

[0026] The working process of this embodiment is as follows:

[0027] 1. Apply the ointment to the lower surface of the sponge body 4, and then place the entire device into the cavity.

[0028] 2. Align the tip of the sponge 4 with the deepest part of the target carious tooth 5, so that the surface of the sponge 4, the inner wall of the groove 3, and the inner side of the limiting member 3a tightly wrap the target carious tooth 5, bite the groove 3, increase the tightness of the contact between the target carious tooth 5, the sponge 4, the groove 3 and the limiting member 3a, and maintain the biting state for 2 to 3 minutes.

[0029] 3. Remove the device from your mouth and rinse your mouth with water to remove any remaining ointment.

[0030] The present invention has been described in detail above with reference to its embodiments. Various improvements can be made without departing from the core scope of the present invention, and equivalent components can be used to replace some of its parts. As long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. This specification does not exhaustively describe these combinations, merely for the sake of saving space and resources. Therefore, the protection scope of this invention is not limited to the specific embodiments disclosed herein, but covers all technical solutions falling within the scope of the claims.
