Description

A dosing device for nest ditch sealant

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a quantitative feeding device for a pit and groove sealant.

Background

As the occlusal surface of the molar teeth newly grown by children is uneven and is a place where the point gap pits and furrows are gathered, the pits and furrows are deep and easy to accumulate food residues, thereby providing favorable conditions for the growth of bacteria, and the uneven pits and furrows can be decayed after a certain time, namely pit and furrow caries; as the degree of mineralization of newly grown teeth is at a relatively low level, caries develops at a relatively rapid rate.

The first permanent molar is the permanent tooth which is the first eruption in the mouth of the child and is also the strongest tooth, the chewing function of the first permanent molar is the strongest, but the tooth position which is most easy to cause caries, once the caries is damaged, the first permanent molar not only can influence the growth and the beauty of the jaw face of the mouth, but also can influence the normal development of the chewing function and the digestive system, and therefore, the protection of the first permanent molar of the child is particularly important.

According to the fourth oral epidemiological survey in China, more than 90% of the permanent tooth caries of teenagers in China are pit and furrow caries, and pit and furrow sealing is the most effective method for preventing the permanent tooth caries of molars at present.

The pit and fissure sealing is a method for preventing pit and fissure caries by coating pit and fissure sealing material on pit and fissure points on occlusal surface and buccal and lingual surface of dental crown without damaging dental tissue, solidifying and hardening after the pit and fissure sealing material flows into and permeates the pit and fissure to form a protective barrier which is covered on the pit and fissure and can prevent cariogenic bacteria and acidic metabolites from eroding the dental body. Pit and fissure closure is a painless, non-invasive method, and the technology has been used internationally for over 50 years. The pit and groove sealing material is named as pit and groove sealing agent, which is cured to adhere closely to the wall of the groove, has certain chewing pressure resistance and no harm to human body, and is non-toxic after being cured. The sealant can be generally reserved for a long time, and is rechecked for 3-6 months so as to find whether the sealant falls off in time and make up for the falling of the sealant. After the pit and furrow are sealed and treated, the original bacteria in the pit and furrow block the source of nutrition, die gradually, and the external cariogenic bacteria can not enter, thereby achieving the purpose of preventing pit and furrow caries.

In the prior art, the feeding device for the pit and trench sealing agent has the following disadvantages: the feeding amount of the pit and fissure sealant can not be accurately controlled, if the feeding amount is too much or too little, the treatment operation is increased, the treatment time is prolonged, and the comfort level and the matching degree of children can be reduced; if the feeding device is mistakenly collided with the solution when being idle, the material is overflowed, the material is wasted, and the number of teeth used for each tube of pit and fissure sealant is reduced.

In order to solve the technical problem, the utility model provides a quantitative feeding device for a pit and ditch sealing agent.
