Examination of chewing wear of teeth
Chewing wear, also known as attrition, generally occurs on the tooth surface or the cutting edge, but can also occur on other tooth surfaces when the dentition is disordered. Since the retention time of the deciduous teeth is shorter than that of the permanent teeth, the degree of chewing wear is not as good as that of the permanent teeth. After the permanent teeth erupted for several years to several decades, there was obvious chewing wear on the posterior teeth and the anterior teeth. Beginning with a smooth facet on the tip or ankle of the tooth, the cutting edge is slightly flattened; as the age increases, the chewing wear is more pronounced, the height of the tooth is lowered, the slope of the tooth is flattened, and the diameter of the tooth is reduced. In some areas of the tooth, the enamel is completely worn away into sharp edges and the dentin is exposed. When chewing, because each tooth has a slight movement, the contact points of adjacent teeth rub against each other, and wear will occur, making the original point contact become a planar contact, which easily causes food jamming, adjacent surface flaws, and Periodontal disease.
Diagnosis
Differential diagnosis
Differential diagnosis of chewing wear of teeth
There is no difficulty in diagnosing according to clinical manifestations, but physiological wear and pathological wear are to be identified.
The wear of the teeth is a physiological phenomenon that benefits both the supporting tissues of the teeth and the chewing function.
The premature wear and tear caused by the development of the hard tissue of the teeth, the dentition caused by the degradation of the human evolutionary jaw system, and the resulting uneven wear are all pathological wear.
