Endodontic Output in Public Healthcare under Different Instrumentation Techniques: A Quantitative and Qualitative Study

Objective: To evaluate output of endodontic in oral public healthcare by analyzing differences in instrumentation techniques, quantitative and qualitatively. Material and Methods: Endodontic services were differentiated by instrumentation techniques: hand techniques with stainless steel instruments (SS) or rotary using NiTi rotary instruments. Secondary data on the productivity of 2011 were obtained from the information system. Student’s t and Mann-Whitney tests were used. Qualitative data were based on semi-structured interviews, direct observation and field diary. Results: Service I employed SS hand techniques, service II used both techniques, while NiTi rotary system was used in service III. Statistically significant differences were observed in total endodontic productivity, with I presenting more productive results than II (p=0.001) and III (p=0.009); III presenting more productive results than II (p
