Surface finds belonging to the temple were first noted in 2019 during restauration work on the ancient city walls of Pae-stum. Analysis of aerial imagery and geophysical prospection has made it possible to locate the site of temple in the north-west quarter of the ancient city near the fortification wall. The area is currently under excavation. The present paper sum-marizes what we know so far based on prospection data and on more than 230 fragments that can be attributed to the temple, including fragments of the stylobate, columns, capitals, architrave, frieze, geison and sima. The temple, which ap-pears to have been a small peripteros with 4 x 7 columns, shedsnew light on the development of Doric architecture and building techniques in Paestum between the Archaic and the early Classical perio

Comparison of debris extruded apically and working time used by ProTaper Universal rotary and ProTaper retreatment system during gutta-percha removal

OBJECTIVE: The aim of this study was to evaluate the in vitro action of ProTaper retreatment files and ProTaper Universal in the retreatment of mandibular premolars. MATERIAL AND METHODS: The amount of debris extruded apically was measured and the time to reach the working length and to complete the removal of gutta-percha was observed. Thirty teeth had their canals prepared using ProTaper Universal files and were obturated by the single cone technique. The teeth were then stored at 37ºC in a humid environment for 7 days. During the use of the rotary instruments for root canal filling removal, the apical portions of the teeth were attached to the open end of a resin tube to collect the apically extruded debris. RESULTS: ProTaper Universal files were significantly faster (p=0.0011) than the ProTaper retreatment files to perform gutta-percha removal, but no significant difference was found between the files regarding the time to reach the working length or the amount of apical extrusion. CONCLUSIONS: ProTaper Universal rotary had better results for endodontic retreatment, and both techniques promote similar apical extrusion of debris
