The article represents the results of data analytical processing considering the equivalent for dental treatment cost estimation among victims of traffic accidents with dental and maxillofacial injuries, and analyzes the objective association level of this criterion with the parameters of the approaches used for expert assessment of maxillofacial trauma injuries. Objective of the study is to analyze the equivalent for dental treatment cost values among victims of traffic accidents with dental and maxillofacial trauma injuries, and to establish an objective level of associations of this criterion with the parameters of the approaches used for expert assessment of maxillofacial trauma injuries. The design of the work included analytical processing of data obtained from previously conducted studies of retrospective and prospective nature, related to the economic component of patients’ rehabilitation due to the maxillofacial injuries occurred after road traffic accidents. The studied parameters were: the cost of treatment, duration of hospitalization, the criterion used to assess traumatic injuries of the maxillofacial region, correlation values relating trauma characteristics with the final cost of treatment and duration of hospitalization, statistical reliability of the relationships between the studied indicators of previously conducted research. Research methods: analytical, prognostic assessment, regression analysis. Current approaches used for expert severity assessment of the maxillofacial trauma injuries occurred after road accidents characterized by limited opportunities to predict and stratify the costs associated with the necessary future dental treatment of victims, but provide a sufficient level of objectification of functional and structural disorders. The increase of the expert severity assessment criteria of maxillofacial trauma injuries, in particular FISS and MFISS scores, is associated with an increase in the cost of appropriate comprehensive treatment and the potentially required duration of hospitalization, but these associations are characterized by uneven patterns of statistical dependences, and an increase in FISS and MFISS indicators beyond certain limit levels provokes a sharp advance in the cost of treatment due to the need for a longer hospitalization of the patient.

Information about the differential diagnosis of human bodily injuries, which were formed when the body, wheel and bottom of a modern car came into contact with the body of a pedestrian; a person on the road surface, in the cabin of a modern car (driver and passengers), when a cyclist comes into contact with a car, in cases of combined types of car injury, is not enough. The purpose of the study is to increase the objectivity of forensic examinations by determining the criteria for assessing damage to the dental system in cases of the most common types of accidents: collision of moving vehicle with man; run over the body with a wheels or the bottom of vehicle; at an injury inside the vehicle on the basis of the analysis of morphological features and the mechanism of the specified damages. The archival materials of 130 forensic medical examinations of the municipal institution “Odessa Regional Bureau of Forensic Medical Examination” concerning victims of living persons and corpses as a result of traffic accidents that were accompanied by their injuries in the period 2015-2020 were used. The following research methods were used: anthropometric, morphometric, photographic, radiological, statistical. The article presents our own experience of improving the objectivity and provability of forensic examinations by determining the criteria for assessing damage to the dental system in cases of the most common types of vehicle: collision of moving vehicle with man; run over the body with a wheels or the bottom of vehicle; at an injury inside the vehicle on the basis of the analysis of morphological features and the mechanism of the specified damages. It is proved that according to the degree of gravity of physical injuries (health disorder or disability), damage to the dental apparatus in traffic accidents should be investigated only in cases of isolated injuries. In this case, fractures of the jaws, regardless of their nature, should be assessed as moderate injuries according to the criterion of long-term health disorders; Crown fractures, traumatic tooth dislocations, and soft tissue fatal wounds should be considered simple injuries that have caused short-term health disorders. Abrasions, bruises should be attributed to simple injuries. Thus, it is impractical to separately determine the severity of the injury of the dental system in cases run over the head with a wheels or the bottom of vehicle - in these cases, we always deal with gross, massive destruction of the bones of the skull.

Annotation. The article attempts to highlight the problems that forensic experts face during the examination of victims of a motor trauma, propose a modern classification of this type of traffic accident suitable for experts, list those issues that require expert resolution, and establish a standard algorithm (sequence) of conducting such an examination. The material of the study was archival copies of expert opinions and acts of comprehensive forensic medical and transport- trassological examinations in cases of motor injuries (33 complex examinations and acts in total), for 2008–2018. Expert studies were conducted on the basis of the Odessa Regional Bureau of Forensic Medicine expertise. The research method is the analysis of forensic and transport-trassological signs in their interconnection and interdependence, allowing to resolve the basic questions about the mechanism and circumstances of motor trauma. The study suggests that the following main types of motorcycle injuries are currently the most common (this includes injuries when operating a “classic” motorcycle and a moped): injury to driver and passenger due to contact of a motorcycle (moped) – with another vehicle, – with a stationary object, – due to the rollover of a motorcycle (moped) without contact with another vehicle, – as a result of a fall from a motorcycle (moped) until it capsizes without contacting another vehicle, – due to contact of the motorcycle (moped) with a pedestrian (pedestrians); injury to pedestrians due to contact with a moving motorcycle (moped); combined injuries of the driver and passenger of a motorcycle or moped (injury due to the rollover of a motorcycle or moped followed by contact with another vehicle; injury due to successive contact of a motorcycle or moped with a pedestrian and stationary object; injury due to rollover of a motorcycle (moped) and falling into a water body or fire, etc.); combined types of injury to a pedestrian (pedestrians) due to contact with a moving motorcycle or moped (injury due to contact with a moving motorcycle or moped, followed by falling and rolling wheels of another vehicle; injury due to contact with a moving motorcycle or moped, and then dropping another vehicle onto the body funds, etc.). Thus, establishing the exact circumstances of a motorcycle injury is impossible by examining only some object artificially isolated from the rest (for example, a corpse). Such an expert approach should be completely abandoned. The author’s proposed classification of motorcycle injuries, which is based on an integrated approach to the study of the mechanism of accidents, and which reflects its main types, can be used for expert purposes.
