Hi,
Let me clear this up. Your cost of rct depends on the material used. If the doctor is using files to perform rct worth 2k to 3k that is protaper,tf files, m2 and rotary machines then your rct cost can be 3k to 4k without cap as the products used are expensive. These files have a short life and restocking it is expensive. Also they need rotary equipment that cost between 40k to 2lakhs. Hence the cost trickles down to the patient. But if the doctor is using basic hand k file that cost 600-700 rs then prices like 3k to 4k is too much and the basic cost should not be more than 2k to 3k with cap(assuming the cap is basic). Always talk to the doctor and ask the equipments and materials that the doctor is gonna use. If he explains well and justifies his price and is using good equipments and follows sterilization protocols the high price is ok. Private clinics are usually preffered as they can change equipment depending on affordability of the patient, this flexibility is not available at corporate clinics as their prices are standardised but you can avail dental loans there.
