Evaluation of Different Coronal Sealing Materials in the Endodontically Treated Teeth: An In Vitro Study

Abstract

In vitro studies have shown that rapid penetration of bacteria in the entire root canal system may occur after endodontic treatment without a coronal seal. A proper restorative technique is necessary to ensure a coronal seal and protection of the residual dental structure. The aim of this in vitro study was to evaluate the coronal sealing ability of the most relevant clinical materials by means of dye penetration (neutral red dye, Sigma-Aldrich, Germany), through a light spectrometric device, and to establish which one of the tested dental materials possesses the best sealing ability. Forty-two extracted teeth were prepared and used for this experiment; they were sealed with 5 different cements. The flow composite had the best absorbance value with 0.00675 ± 0.00096 (mean ± standard deviation) for monoradicular samples and 0.025 ± 0.00129 for pluriradicular samples. Under the constraints of the present study, both flowable and packable composite materials can be recommended as orifice sealing materials to prevent microleakage in an endodontically treated tooth. To assess the clinical superiority of any material, further in vivo studies are required.

Comparative Analysis of Coronal Sealing Materials in Endodontics: Exploring Non-Eugenol Zinc Oxide-Based versus Glass-Ionomer Cement Systems

“…A total of seven in vitro studies 3,[11][12][13][14][15][16] were deemed eligible for the current systematic review. The included trials encompassed a total of 378 extracted human teeth.…”

“…However, at the 1-week and 1-month intervals, Coltosol exhibited superior sealing performance compared to Compoglass. Hajaj et al 12 compared the characteristic sealing in singlerooted and multirooted teeth and found that GIC exhibited superior sealing performance in single-rooted teeth compared to Coltosol.…”

“…Hajaj et al 12 compared the characteristic sealing in single-rooted and multirooted teeth and found that GIC exhibited superior sealing performance in single-rooted teeth compared to Coltosol.…”

“…Almost all of the evaluated studies employed colored stains or dyes to assess the seal quality of various temporary sealing materials. Among the five studies examined, only Hajaj et al 12 investigated the sealing properties of GIC in both single-rooted and multirooted teeth. Their findings revealed superior sealing performance in single-rooted teeth compared to zinc oxide-based materials, specifically Coltosol.…”

“…Following root canal treatment, GIC can be applied for the coronal sealing of multirooted teeth. 18 However, the reviewed study 12 has not extensively addressed crucial factors, including challenging tooth anatomy, load-bearing requirements, adaptability, and long-term durability. Additional research is required to gather conclusive evidence regarding the effectiveness of either of the tested material types in achieving successful sealing in multirooted teeth.…”
