Abstract

Objective: This study aimed to compare the difference in marginal dye penetration between ever-Stick, Parapost XP, Parapost fiber white and control groups under gradual loading. Materials and Methods: Sixty-eight human maxillary permanent incisors were divided into four groups. Each specimen was endodontically treated with step-back technique and prepared for each post system according to experimental groups, subsequently cemented in the canal. Composite resin cores were built and laboratory fabricated metal crowns were cemented. All specimens except those in the control group were subjected to thermal cycling. All groups were subjected to gradual loading from 0N-50N for 100 cycles. Specimens were sectioned transversely and the depths of dye penetration along the post were measured. Data were entered in SPSS ver. 22 and analyzed using two-way ANOVA test. Results: There was no significant difference in marginal dye penetration between each group (p-value>0.05). However, there was a significant difference in percentage of marginal dye penetration between all groups (p-value

Abstract

Background: The purpose of this study was to compare the adaptation of fiber reinforced composite post system and cast post-and-core. Methods: 17 extracted human permanent maxillary central incisors were endodontically treated following the standard protocol. 17 fiber reinforced composite post had been fabricated and adapted to the prepared parallel root canals. A light body poly vinyl siloxane (EXAMIX NDS, Japan) impression material was inserted into the root canals followed by the post. A digital scale was used to measure the weight of the remaining material that filled the gap between the post and the canal wall. The adaptation was indicated by the weight difference before and after impression material insertion. The same procedures were repeated with 17 cast post-and-core in the same teeth specimens. Result: The mean difference for the weight of the material within the group was statistically significant (P-value 0.05). Conclusions: Both cast post-and-core and fiber reinforced composite post systems showed similar adaptation to the canal.

Abstract

Svrha istraživanja: Namjera je bila usporediti prilagodbu kompozitnih intrakanalnih kolčića ojačanih vlaknima i lijevanih nadogradnji. Materijal i metode: Sedamnaest izvađenih ljudskih trajnih gornjih središnjih sjekutića endodontski je izliječeno prema standardnom protokolu. Sedamnaest kompozitnih intrakanalnih kolčića ojačanih vlaknima prilagođeno je prepariranim paralelnim korijenskim kanalima. Nisko viskozni vinil-polisiloksan (EXAMIX NDS, Japan) za otiske unesen je u korijenski kanal nakon kolčića. Digitalnom vagom izmjerena je masa preostalog materijala koji je ispunjavao prazninu između kolčića i unutarnje stijenke kanala. Prilagodba je određena na temelju razlika u masi prije unošenja otisnog materijala i nakon toga postupka. To isto ponovljeno je sa 17 lijevanih nadogradnji na istim zubima kao uzorcima. Rezultati: Srednja razlika u masi materijala unutar skupine bila je statistički značajna (p vrijednost < 0,001) s vrijednošću od 6,1 mg (± 2,7mg) za lijevane metalne nadogradnje i 6,4 mg (± 2,7mg) za kolčiće ojačane kompozitnim vlaknima. No srednja razlika nije bila statistički značajno različita kada su se uspoređivala oba materijala (p vrijednost > 0,05). Zaključak: I lijevana nadogradnja i vlaknima ojačani kompozitni intrakanalni kolčić slično su se prilagodili stijenkama korijenskog kanala., Background: The purpose of this study was to compare the adaptation of fiber reinforced composite post system and cast post-and-core.
