Certain Risk and Uncertainties	Certain Risks and Uncertainties The military conflict between Russia and Ukraine and its impact on the economy has caused significant worldwide challenges. While the situation is highly uncertain and evolving, its impact on the economy, including inflation, volatilities in the financial market, supply chain challenges, impacts on consumer confidence, purchasing power, sanctions and retaliatory sanctions among others, have impacted and could potentially subject our business to materially adverse consequences should any portion of its impacts become prolonged or escalate beyond its current scope. Further, as the COVID-19 pandemic continues and new variants of the virus emerge, we are continuing to see fluctuations in the numbers of patients seeking treatment for dental services and the number of doctors providing services and treatments globally. The full extent to which the pandemic, including as a result of any new variants, business restrictions or lockdowns, and the impact of vaccinations, will directly or indirectly impact our business, results of operations, cash flows, and financial condition will depend on future developments that are highly uncertain and cannot be accurately determined. Additionally, we could also be materially adversely affected by uncertain or reduced demand, labor shortages, delays in collection of outstanding receivables and the impact of any initiatives or programs that we may undertake to address financial and operational challenges faced by our customers.
