Kohn's signs are a group of diagnostic signs proposed by Isidore I. Kohn to identify Kellmacheriodis disease. Kona signs are objective and reliable criteria for diagnosing this rare hereditary disease associated with abnormalities in dental development.
The concept of Kohn's signs was introduced by I.I. Kohn in 2006, when he examined patients at the clinic of the Faculty of Dentistry of the Hebrew University of Jerusalem. Until this point, there was no clear way to diagnose Kellmacher disease. Kona's signs have not been able to pass all the necessary tests and receive official recognition as diagnostic criteria. However, their use has become one of the key methods for diagnosing this disease.
Kona signs are complex. These include determining tooth color; assessment of the presence of pericoronal dental plaque that tightly envelops the teeth; Look for crooked, biconvex or uneven tooth surfaces. The condition of the gums is also taken into account to assess their density and texture. In addition, the doctor should pay attention to the frequency of dental hygiene in the patient, as well as obvious external changes in the teeth.
It is important to remember that Kona signs must be confirmed by x-ray examination. This is the only way to get a complete picture and eliminate possible errors. If the patient has already undergone treatment, then it is necessary to compare Kona signs with the results of previous studies to ensure the correct diagnosis.
