Abstract The naturally occurring isoprene rubber component of gutta-percha has been used in dental root canal filling treatments for almost a hundred years owing to its stability and plasticity as a root canal filling material. The traditional warm gutta-percha vertical compaction technique is the major technique for warm gutta-percha root canal ...

Warm vertical compaction sequences in relation to gutta-percha temperature
Journal of Endodontics, 1997The aim of this study was to analyze warm vertical compaction sequences in relation to the temperature variations of gutta-percha. Twenty-four maxillary incisors were obturated according to two different instrumentation techniques: Compaction and heating were performed with either the monomanual classical or bimanual method.

Analysis of the forces developed during obturation: Warm vertical compaction
Journal of Endodontics, 1997The aim of this work was to measure and analyze the forces applied by endodontists during an obturation. This was achieved by devising a system of force transducers linked to acquisition software. The software allowed us to study the obturation forces in real time or to store them.

An in vitro technique was developed to evaluate the ability of various filling techniques to fill an artificial standard root canal system. No significant difference was observed in volume changes between lateral condensation, vertical (warm) condensation, or compaction (mechanical) condensation during a two-week period.

AbstractThis study aimed to compare the effect of a bioceramic sealer (iRoot SP) and a resin‐based sealer (AH Plus) on the outcome of root canal treatment in a 2‐year follow‐up. Seventy‐six teeth with irreversibly or necrotic pulp were recruited. After instrumentation and disinfection, the root canals were obturated using warm vertical compaction with ...

Stresses under warm vertical compaction
British Dental Journal, 1999Objective This study was designed to investigate the effect of certain pathological alterations of the dental structures (diminishing bone support, internal resorption, root perforation, periapical lesion) on stress distribution during root canal filling procedures by the warm vertical compaction technique.

The purpose of this in vitro study was to compare quantitatively the density of standard cold lateral gutta-percha compaction and warm vertical compaction by using the continuous wave of condensation technique. Forty transparent acrylic blocks with 30-degree, curved root canals were instrumented using Gates Glidden burs and Profile 0.06 taper rotary ...

The sealing ability of root canal filling materials is crucial to the goal ofpreventing reinfection via microleakage of microorganisms and their by-products.Thirty palatal canals of 12mm length from extracted upper first molars were selectedthen instrumented and divided into 3 groups. Group I was obturated with lateralcompaction technique, group II was

The purpose of this study was to compare the adaptability of gutta-percha after varying the depth of heat application in the obturation of a set of standard root canals. A split-tooth model was constructed using a human maxillary central incisor. The root canal was cleaned and shaped using a step-back preparation to a size #60 FlexOFile at the working ...
