COMPARISON OF ROOT CANALS OBTURATED WITH PROTAPER GUTTA-PERCHA MASTER POINT USING THE ACTIVE LATERAL CONDENSATION AND THE SINGLE-CONE TECHNIQUES: A BACTERIAL LEAKAGE STUDY

Aim: The aim of the present study was to assess the recontamination acupatch time of root canals filled with ProTaper gutta-percha master point using the active lateral condensation and the single-cone techniques.Methods: Fifty premolars, after biomechanical preparation, were randomly divided into six groups according to the obturation technique an

The surrounding rock of the roadway under double gobs in the lower coal seams is partially damaged by the mining of the upper coal seam and the stress superimposition of the stepped coal pillars.What is worse, the upper layer of the roof is collapse gangue in double gobs, which makes the anchor cable unable to anchor the reliable bearing layer, so

Rural communities in Mexico and other countries with limited economic resources require a low-cost measurement system for the piezometric level and temperature of groundwater for their sustainable management, since anthropogenic action (pumping extractions), natural recharge and climate change phenomena affect the behavior of piezometric levels in

The occurrence and development of chicago cubs earrings tumor is mediated by a wide range of complex mechanisms.Subsequent to nitric oxide and carbon monoxide, hydrogen sulfide (H2S) holds the distinction of being the third identified gasotransmitter.Alternation of H2S level has been widely demonstrated to induce an array of disturbances in importa
