Solubility and pH of bioceramic root canal sealers: A comparative study

Abstract

BackgroundThis study compared the solubility and the pH of different root canal sealers in vitro.Material and MethodsBioRoot™RCS, TotalFill BC Sealer, MTA Fillapex, SealapexTM, AH Plus, EasySeal, Pulp Canal Sealer™ and N2 were tested. Similar specimens were prepared using ring molds with an internal diameter of 20 ± 0,1 mm and a height of 1,5 ± 0,1 mm and digitally weighted to register the mass of each specimen before and after immersion in distilled water. Solubility was determined after 24 hours and statistically analysed using a one-way ANOVA test and post-hoc Tukey test. The pH value was measured by a digital pH meter after 3 and 24 hours from manipulation.ResultsBioRoot™RCS and TotalFill BC Sealer showed significantly higher solubility (P<0.05). All the remnant root canal sealers fulfilled the requirements of solubility of the International Standard Organization 6876 demonstrating a weight loss of less than 3%. BioRoot™RCS and Totalfill BC Sealer exhibited high alkaline pH over time (P<0.05); the alkalinity of the other tested cements was significantly lower.ConclusionsThe prolonged alkalinity of bioceramic sealer matched the increase in solubility. This may encourage their biological and antimicrobial effects, but the ongoing solubility may impact their ability to prevent apical leakage. Key words:pH, root canal sealers, solubility.

Właściwości alkalizujące wybranych krzemianowo-wapniowych uszczelniaczy kanałowych. Badanie in vitro

“…Różnice w metodyce dotyczą również przechowywania próbek, ich wielkości oraz postaci, w jakiej materiały umieszczano w roztworze (postać niezwiązana względnie związana). Podobnie jak w badaniu własnym próbki inkubowano w tym samym roztworze przez cały okres badania, nie wymieniając go na nowy po wykonaniu pomiaru [16,32,33], choć wielu autorów po rejestracji pH umieszczało próbki w świeżym roztworze o pH zbliżonym do obojętnego [23,24,27,30], a inni w ogóle nie podali informacji na ten temat [25,31].…”

“…W cytowanych badaniach próbki umieszczano w wodzie, gdy uszczelniacze były niezwiązane. Natomiast w niektórych badaniach dotyczących właściwości alkalizujących uszczelniaczy kanałowych ocenie poddano związane materiały, wykonując z nich z użyciem matryc próbki w formie krążków lub walców o różnej średnicy i wysokości (5 × 1 mm; 8 × 1,6 mm; 10 × 1 mm; 7,75 × 1,5 mm, 20 × 1,5 mm) [16,25,27,32,33].…”

Effect of immersion in distilled water or phosphate‐buffered saline on the solubility, volumetric change and presence of voids within new calcium silicate‐based root canal sealers

“…TotalFill BC has adequate physicochemical properties, but appears to be soluble (Poggio et al . , Tanomaru‐Filho et al . , Colombo et al .…”

“…Premixed, ready-to-use calcium silicatebased endodontic sealers, such as EndoSequence (Brasseler, Savannah, GA, USA) and TotalFill BC Sealer (FKG Dentaire, La Chaux-de-Fonds, Switzerland), have been studied (Zamparini et al 2019). TotalFill BC has adequate physicochemical properties, but appears to be soluble (Poggio et al 2017, Tanomaru-Filho et al 2017, Colombo et al 2018. Recently, the new calcium silicate-based Sealer Plus BC (MK Life, Porto Alegre, RS, Brazil) and Bio-C Sealer (Angelus, Londrina, PR, Brazil) were developed and introduced.…”

A Comparison of Solubility of Endosequence Root Repair Material Fast Set Putty and Mineral Trioxide Aggregate: An in Vitro Study

“…There are no studies done on solubility of endosequence root repair material. EndoSequence Root Repair Material contains many of the same characteristics as BC sealer, with similar chemical composition .study done by poggio et al, showed Endosequence BC sealer showed higher solubility as a result of hydrophilic nanosized particles being present which increases their surface area and allows more liquid molecules to come into contact with them which can be compared with the current study [22].…”
