Earlier, dentists used to use hand instruments and take multiple visits for completing root canal treatment. This is uncomfortable to the patient and can result in discontinuation of treatment. Now a days rotary (automatic- machine operated) root canals are done which are more precise and faster making Single Visit Root Canal Treatment possible.
Research hasshown that single sitting root canals, when performed in an appropriate case, have results similar to multiple sitting root canals. These are possible when the amount of tooth infection is minimal.
