9-month-old infants can determine whether they are circumcised or not by looking at whether the maxillofacial morphology is abnormal or not, by looking at the degree of movement of the mandible, and by measuring through X-ray cephalometrics.
1. To see if the shape of the jaw is abnormal: to see if the shape of the jaw is abnormal is mainly due to the fact that the incisors of infants and young children are hindered in the process of growing out, resulting in a simple malocclusion.
2. Look at the degree of activity of the mandible: some functional geoblasts also have anterior protrusion of the mandible, but only the functional mandible is in the front, and the size, shape and development of the mandible are basically normal. Functional mandibles can be normally retreated to the front teeth in relation to the edge, but if it is a bony covering of the mandible, the mandible can not be normally retreated after anterior protrusion, and it needs to be corrected in order to be slowly restored.
3. Measurement by X-ray cephalometric: X-ray cephalometric can accurately determine the angle of the mesial incisal incisal point closure tract, the larger the angle, the more it should be counted as a bony pericoronary, and this method is also a more accurate way to determine.
If parents suspect that their infant’s condition is serious, they can go to a regular hospital for examination and diagnosis.
