Whether the geodesic is bony or dental can be judged by imaging examination, taking whole mouth surface tomogram or lateral cephalometric film, or from the cause of pathogenesis, clinical manifestations, facial morphology and positional relationship of molar teeth.
1. Imaging examination: Lateral cephalometric films and surface tomograms can be taken by X-ray examination or CT examination, the former can understand the inclination angle of the anterior labial teeth and the development of the jaws, and the latter can understand the condition of the temporomandibular joints. If there is a problem with jaw development, it is usually a bony pericoronitis, and on the contrary, it may be a dental pericoronitis, and the specific diagnosis should be analyzed together with the clinical history.
2. Pathogenesis: Bone paronychia is usually caused by abnormal development of the jaws, which leads to abnormal jaw position; dental paronychia is usually caused by abnormal tooth replacement or eruption, which affects the position of the jaws.
3. Clinical manifestations: Bony paronychia is often accompanied by maxillary hypoplasia or mandibular hypoplasia while anterior teeth anticuspension occurs; dental paronychia is purely manifested as anterior teeth anticuspension without jaw hypoplasia.
4. Facial shape: Bone paronychia tends to lead to concave facial shape; dental paronychia usually does not change the shape of the face.
5. Molar position relationship: when the incisal end of the upper teeth and the incisal end of the lower teeth bite together, if they cannot bite, then it may be a bony pericoronation, and its molar position relationship shows a near-medium misalignment; if they can bite, then it is mostly a dental pericoronation, and its molar position relationship shows a neutral relationship.
If there is a case of paronychia, you should go to the hospital for a professional examination, and after a clear diagnosis, you should carry out the treatment as soon as possible.
