Eighteen days of the full-scale Russian invasion into Ukraine gave us urgently a need to rethink the ways we can run private dental and oral surgery practice. Wartime dictate us completely different and sometimes highly risky agenda. For the need to provide emergency dental care and oral surgery to those residents of the city/village who cannot or do not want to be evacuated from the regions of hostilities, some private practices continue to work. Although they are not providing a full range of services, they are highly efficient even carrying out emergency care, e.g. 16 private practices in Kyiv during the first 13 days of Russian-Ukraine war of February-March 2022. Among problematic sides of managing private clinic in war zones are: (1) supply chain disruption (Williams, 2013) of the dental and oral surgery materials, (2) interruption in work of dental technicians or complete cessation of their activities due to the evacuation or absence of materials, (3) termination of work of diagnostic centers that are important for diagnosis establishment and for control of treatment results, (4) difficulties (increased price for taxi and risks for life) for patients and staff members on transfer to the clinic, (5) significant decrease of clinic`s personnel members due to the possible evacuation, (6) decrease of the number of performed procedures due to the paragraphs 1, 2, 3, and 5, (7) the need to go down to the bomb shelters in case of air alarm, forcing the interruption of treatment procedure, (8) injury of the staff members, (9) significant decrease of amount of financial resources due to the paragraphs 1, 2, 3, 4, 6, etc.

During the last 30 years of Ukrainian independence the private dental businesses are flourishing what is a very good sign not only for patients and dental professionals, but also for economy. As of January 1, 2019, 4,584 privately owned dental institutions were registered Ukraine. Among them, 669 were dental clinics and 3,915 – dental offices.1 Generally, dental care in Ukraine (as of January 1, 2019) was provided by 25,651 dentists of six specialties.1 According to these 2019 data, we can hypostatize that every sixth dentist in Ukraine is an owner of a private clinic/office.1 Moreover, as of January 1, 2021, the number of private dental practices for the first time in history of this country increased to 5,084 (ie, showed a 8.72 percent growth during a 2019 to 2021 period).

Someday the owner of the private dental and oral surgery practice can decide to sell it. In some cases, this is because the owner wants to move away from dental matters completely; To move away from business not only as a dentist or oral and maxillofacial surgeon but even as a shareholder. Regardless of personal motives for the sale, the deal and the cost of whole practice should not be underestimated. The price is to be based on a correct calculation of the next dental clinic data: Human resources (number of specialists, types of their specialization, experience, etc.), number of dental chairs, equipment, package of state permits for dental business and types of dental specialties that are included in the license of this clinic to conduct business in medical practice, presence of ISO 9001 certification for the clinic, established connections with partners (dental technicians, companies of dental products and equipment, insurance companies, etc.), types of diagnostic, treatment, and prophylactic procedures carried out in the clinic, base of clients, availability of consulting doctors, existence of communications with University chairs and associations/societies, presence of cooperation agreement with Pathology Department, location of the branch of the chair on the basis of the clinic, number of years at the market, longevity of the same team (Woody [2018] notes that 10-plus years for the same team is one of the best indicators for buyers),1 the size of real estate, location in the country and in the city/village (distance from the neighboring countries, airports, metro stations, and other transport nodes), the commercial real estate is owned or leased, real estate is a separate building or included to the multiple apartment building, presence of the rooms for the educational or hands-on training, courses that have been performed on the basis of this clinic, team experience in organization of the dental meetings, a state and international reputation of the practice, etc.

Day 247 of a full-scale Russian invasion in Europe. The recent rocket attack on Kyiv during the morning commute and an attack by kamikaze drones is not something that can contribute to a positive work atmosphere and a boom in job interviews. Such continuous acts of terrorism can only cause a disruption in the chains of work processes. In stomatology, such chains cannot be built overnight. Typically, it takes years of collaboration and growth of the trust. The quality of the relationship between the members of the chain, speed of collaboration, accessibility of stomatologist for the particular patient are vital for the success of the entire chain having a positive effect on profitability and existence of the whole (Huntley, 2006; Atrek et al, 2014; Nagorniak, 2022). On other hand, such gaps in the chains of work processes are the chances for the young, less experienced stomatologists of all specialties—orthodontists, prosthetic stomatologists, surgeons focused on dental implants, etc. A chance to take the place of more experienced and famous stomatologists. Summarizing the 247 days of Russia's war of aggression against Ukraine, the following conclusions can be drawn regarding the disruption of work process chains in Kyiv city and options for their resolution.
