Análise do desempenho do sistema ProDesign Logic na etapa de preparo químico-mecânico do sistema de canais radiculares: revisão de literatura

Abstract

The objective of this review was to evaluate the performance of the ProDesign Logic system (PDL) in the Chemical-mechanical preparation stage of the root canal system, based on the parameters fracture resistance, prepared area, canal transport and centring ability, dentin removal, instrumentation time, percentage of debris and creation of dentinal defects. Through a bibliographic review, 23 studies were selected from the MEDLINE/PubMed database, using the descriptors ("Prodesign Logic OR bassi logic") AND ("fracture OR apical transportation OR centering ability OR unprepared area OR nonprepared area OR dentine removed OR cyclic fatigue OR shaping ability OR root canal preparation"), in addition to manual searches in scientific journals. Thus, it was possible to conclude that PDL has adequate resistance for the instrumentation of long oval canals and satisfactory centring ability, although reciprocating systems present better results for such parameters. The percentage of untoched areas with PDL was high. PDL presented satisfactory results for the dentin removal, allowing conservative preparations, and completed instrumentation more quicky than manual and reciprocating files, but was associated with high percentages of debris and, regarding the formation of dentinal defects, it is not clear whether the system is capable of generating such defects, but further studies are needed to investigate this relationship.
