Root canal sealers in dental practice

Root canal sealers are important materials commonly used in endodontic treatment. Endodontic treatment for cleaning the root canal and removing the pulp and (cid:977)illing with manmade materials. The aim of the study was to assess the knowledge and attitude of the practitioners regarding root canal sealers in endodontic treatment. It is an online-based questionnaire study in which ten questions were circulated through an online forum through google forms and results were analysed using SPSS. In this study, it was observed that private practitioners most commonly use zinc oxide eugenol based sealers (50%), but it shows that methacrylate resin-based sealers (50%) are most effective in sealing. It shows that private practitioners are more aware of root canal sealers and its uses, and about its properties.


INTRODUCTION
The success of optimal endodontic management is due to several important factors, such as appropriate instrumentation, bio-mechanical planning, obturation procedures and, inally, post-endodontic reconstruction. Sealer and sealing material work synergistically to produce hermetic seals (Torabinejad and Walton, 2009). The quality of the seal produced with guttapercha and traditional zinc oxide eugenol sealers is far from perfect. In comparison to resin-based seals, the setting reaction of zinc oxidebased sealers of eugenol is a chelation reaction that occurs between eugenol and zinc concentrations of zinc oxide. Delayed setting shrinkage associated with zinc oxide based sealers is observed (Michaud, 2008). ZOE sealer within pulp chamber decontaminated dental tubules to a depths of 250 micrometres and had strong antimicrobial properties relative to other sealers It comprised of a pasting device supplied in two tubes in a modern dual-barrel syringe. The epoxy paste includes radiopaque illers.
The amine paste consists of three different forms of amines, radiopaque illers and serisol. Only the minimal release of formaldehyde following setting was reported by for AH plus (3.9ppm), followed by EZ-illing (540ppm) of endodontic cement and AH26 (1347ppm) of endodontic cement yielding the strongest release of formaldehyde (Vadde, 2016). In its structure, it has nanosilver. This is a metallic silver that is evenly dispersed on the surfaces of the illing.
This seal creates calcium hydroxide (Camilleri, 2008) that is transferred into solution (Fridland and Rosado, 2003) and induces the formation of hydroxyapatite frameworks in modelled body luids (Sarkar, 2005). Pro root endo seal is a calcium silicate endodontic seal. The main components of pro root endodontic seal powder and tricalcium sil-icate and dicalcium silicate, including calcium sulfate as a retardant environment, bismuth oxide as a radio-paci ier and a limited percentage of tricalcium aluminate when inserted in the canal, release calcium activity and induce adhesion and proliferation. The aim of the study was to assess the knowledge and attitude of the practitioners regarding root canal sealers in root canal treatment.

MATERIALS AND METHODS
It is a descriptive cross-sectional study it includes ten questions circulated among 100 population of dentists in Chennai, and the response was collected through google forms. The data were analysed statistically, and the result was obtained. Analysis software used was SPSS.

Data collection
An online platform known as survey planet was used. The questionnaire was uploaded on this site, and the data was veri ied by an external viewer. Data was reported to excel and later exported to SPSS for analysis. The results were analysed, and the responses were tabulated in the form of bar charts.

RESULTS AND DISCUSSION
Previously our team had conducted numerous clinical trials and survey studies over the past ive years. Now we are focusing on epidemiological surveys. The idea for this survey stemmed from the current interest in our community. In this study it shows that private practitioners are more aware of root canal sealers than community service practitioners. About 58% of them are private practitioners in this study, and 42% of them are community service practitioners (Figure 1). It shows that zinc oxide-based sealers are most commonly used sealers (50%) followed by calcium hydroxide based sealers (44%) and paraformaldehyde based sealers (6%) (Figure 2). It shows that methacrylate resin-based sealers are more effective in sealing (50%) followed by zinc oxide eugenol based sealers (25%) and both (15%) (Figure 3). Zinc oxide eugenol sealer is more commonly used among private practitioners than community service practitioners, calcium hydroxide based sealer is more commonly used among private practitioners. P-value was observed to be 0.9>0.05, and this is statistically insigni icant. (Figure 4).

Figure 3: Bar chart depicts per cent responded for most effective sealer.
Zinc oxide eugenol based sealer follows methacrylate sealers in both private and community practitioners was estimated with P-value 0.7>0.05, which again is statistically insigni icant. (Figure 5). Private practitioners have performed a higher number of root canal treatment than community service practitioners. P-value was determined to be 0.4>0.05; it was statistically insigni icant. (Figure 6).
The study of (Ravikumar and Sharma, 2017), showed a high prevalence for zinc oxide-based sealers showed higher prevalence for AH plus sealer. In the study of (Naghavi, 2014), resin-based sealers are more effective in sealing. The study of (Swanson and Madison, 1987), concluded that methacrylate sealers are the most effective in sealing than other sealers. The study of (Torabinejad et al., 1990), concluded that epiphany and resilon leaked signi i-cantly less than guttapercha and AH26, it shows the leakage property of the sealers. In a study by (Weller, 2008), it was suggested that the newly introduced pro-root endo seal based calcium silicate is more analogous in sealing consistency to the epoxy resin-based seal and seals than the ZOE-based seal after submersion in luidcontaining phosphate. In a study by (Scarparo et al., 2009), it was found that more macrophages were developed by methacrylate composite resins sealers. Research has also shown that epiphany root canal sealers were the only component that demonstrated intraosseous cytocompatibility with resinbased sealants (Sousa, 2006). A number of studies have also shown that Tubliseal EWT had a iner ilm thickness among traditional zinc oxide eugenol sealers. Higher strain rate resulted in a major improvement in the low velocity of all sealers. (McMichen et al., 2003) con irmed that Endomethasone did not follow with ISO requirements among the medicinal sealers. In a study performed by (Souza et al., 2009), it was observed that epiphany had higher low, polymerization stress and weaker strength properties to dentine than AH plus. In the (Kayaoglu et al., 2005), it was observed that AH plus and Grossman's sealer were ef icacious in decreasing the amount of bactericidal activity whereas the calcium hydroxide Sealapex, Apexit were unsuccessful.

CONCLUSIONS
In this study, it shows that zinc oxide sealers are the most commonly used sealers among both originate, and community service practitioners and resinbased sealers are more effective in sealing than other sealers. Private practitioners are more aware of root canal sealers than community service practitioners.
