CASE REPORT: THE FORTH MAXILLARY MOLARS IN WOMAN LIVING IN THE IV CENTURY A.D.

Supernumerary teeth in humans are considered as those addition to the normal series of deciduous or permanent dentition. Distomolars forth molars that erupt behind wisdom found 0,18–3,8% modern population, but quite rare compared other supernumerary teeth. Odontologic studies ancient and contemporary populations allow not only evaluate health state, life style diet people, explain etiology, clinic manifestations treatment dentomaxillary abnormalities. The mostly described people over period XIX-XXІ centuries few researchers presented this variant people.
 aim study was estimate a case human remains, which represented by Chernyachov archarological culture artefacts. Sex death age were established methods widely accepted anthropology. method analysis dento-maxillary region developed authors orthopantomography used for dental examination.
 An undamaged skeleton during archaeologic expedition nearby town Shyshaki, Poltava (burial No 112) 2016 now kept at Archaeological Site Preservation Research Centre (Poltava). Archaeologists defined remains dated end IV c. AD. belonged 1820 years` women good state; no pathological changes found. Maxilla had molar (tooth 19) alveolar sockets 13, 12, 21, 22, 25, 27, 28 29 recorded being lost anteand postmortem. Teeth neither enamel hypoplasia nor tooth wear. Root 19 immature.
 Etiology is still unclear yet, there data supporting atavistic theory. Bilateral distomolars could be symptom systemic abnormalities dentofacial region, studied changes, so abnormality characterized systemic. congenital anomaly associated with chromosome, autosome dominant transmission, do have enough evidence prove such nature anomaly. This more likely related theory hyperactivity lamina follicle development dominates nowadays.
 According morphological classification, our premolar shape.
 Сlinical can different. asymptomatic rarely erupted; they may provoke problems hurt buccal mucosa. Also retained distomolar cause retention pericoronaritis third molar, keratoand paradental cysts, localized periodontitis, decompression lower nerve, manifests itself jaw fracture. Oral signs mobility discomfort feeling retromolar area, bulging mandible. Supernumery X-ray examinations usually taken non-related problems. investigated mosy caused problems.
 Basic fourth extraction observation, however, choice depends on clinical estimation individual risk factors.
 woman non-systemic shape. Taking into account most detected examination, dentists should careful miss abnormality.
