What examination should be done for dental caries: Let’s understand together: oral examination, caries is easy to occur in the retention area where the teeth are not easy to self-clean, especially in the sulcus of the joint surface of the grinding teeth or the crowded food embedding place of the teeth, and its caries depth is divided into three kinds: shallow caries, medium caries and deep caries.
Superficial caries means enamel caries, no cavity is formed on the tooth, the lesion is limited to the enamel, the lesion part of the tooth changes from translucent creamy yellow to light brown or dark brown, there is no subjective symptom at this time, but the shallow caries in the cervical part of the tooth has damaged to the dentin, it should be noted.
Middle carious lesion has damaged to the superficial layer of dentin, the tooth has cavity formation, the tooth is more sensitive to sweet and sour food, especially the cold stimulation is especially obvious, after the stimulation is removed, the symptom disappears.
The deep caries lesion destroys to the deep layer of dentin, the tooth has a more tan cavity formation, the temperature stimulation, chemical stimulation and food into the cavity elbow all cause pain, but in this case, no spontaneous pain.
The harm of tooth decay: tooth decay is very harmful to human oral health, if not treated in time, it will also cause pulp lesion and produce severe pain and sitting and lying down. It endangers human health by destroying the integrity of chewing organs, thus reducing the chewing function and hindering digestion. The progress of this disease is very slow, and it is not easy to be noticed in its past, so it is not treated early.
In addition, caries and its secondary diseases, in general, do not endanger people’s lives and usually do not get people’s attention, which aggravates the seriousness of caries. Especially among the teenagers and children, the incidence of dental caries is very high, and having dental caries will cause great harm to the oral health and even the whole body health of teenagers and children.
Caries lesion type: there are more classification methods, the common ones are as follows.
1, the degree of caries classification enamel caries or dental bone caries).
The caries site is only limited to enamel or bone and has not reached dentin.
Middle caries (dentin shallow caries).
The caries has progressed from the enamel or bone to the superficial dentin stage.
Deep caries (deep dentin caries).
The lesion of caries has developed to the deep layer of dentin, forming a deep cavity, close to the pulp, but has not yet caused irreversible pulpitis.
2.Classification according to lesion occurrence site
According to the occurrence of caries on the tooth surface, it is divided into sulcus caries, smooth surface caries, cervical caries, root surface caries and adjacent surface caries, etc.
3.Classify according to the progress of lesion
According to the speed of caries progression, it can be divided into three types, namely, chronic caries, acute caries, resting caries and secondary caries.
Chronic caries.
It is the most common type of dental caries in the clinic. The caries process progresses slowly, the lesion area is deeply colored, and the texture is dry and hard, so it is also called dry caries.
Acute caries.
It is mostly seen in the patients with poor health condition. The caries process progresses faster, the cavity has more decayed matter and the texture is soft, so it is also called wet caries.
Static caries.
In the process of caries progression, due to the change of pathogenic factors, the caries stops at a certain stage and does not continue to develop.
Secondary caries.
It is the condition that new caries occurs at the edge or underneath of the filling material, mostly because the filling is not decayed or the edge of the filling material is poorly fitted.
