“…However, there were controversial conclusions about the situation. Cicek et al (10) reported that the fracture resistance of root canal was completely filled with MTA was lower than the apical 3mm plug group. Considering these varied results, the present study compared the complete root canal obturation using MTA or apexification MTA with backfilling with GuttaFlow Bioseal.…”

“…However, the average MTA thickness used as the apical plug is an argumental treatment procedure, and the risk of fracture remains as the dentin wall thickness is still thin. In order to use the various advantages of MTA and increase the fracture resistance of the tooth, the rest portion of the root canal can be filled with gutta-percha or similar materials after the apical plug with optimum thickness is formed (10).…”

Objective: This study aims to investigate the effect of different treatment options on immature maxillary central teeth simulated with two different apical diameters on fracture resistance.Methods: Forty-eight maxillary central teeth with a singular root canal were collected for this in-vitro study. The specimens were decoronated to 17±0,12 mm long for ensuring standardization. All samples were randomly divided into two groups: 1,2mm group (G1) prepared with No. 4 Peaso Reamer and 1.8mm group (G2) prepared with No. 6 Peaso Reamer. Each parent group is divided into 4 subgroups (n=6) to form treatment groups. The positive control group was prepared without the access cavity to simulate the immature tooth (P) and negative control (N) group was prepared and filled calcium hydroxide. In group 3 MTA was condensed with a hand plugger to obtain a 3mm thick apical plug and remaining parts of the canals were filled with Guttaflow Bioseal cold filling system (G). In group 4, simulated immature roots were filled completely MTA (M). All samples were kept at 37° C and % 100 humidity for four weeks. Fracture test was performed by applying a load at an angle 135 degrees to the long axis of the teeth until a fracture occured using a universal test device.Results: There was a statistically significant interaction between apical enlargement diameter and fill type on fracture resistance (p<0,05). The fracture resistances of the negative control groups in both of group 1 and group 2 were significantly different from those of the other groups (p<0,05). There was no statistically significant difference in fracture resistance according to filling type in 1,2mm apical diameter groups (p>0,05). GuttaFlow (G) group in the 1,8mm apical diameter group has the highest fracture resistance while the MTA (M) group has the closest fracture resistance to the negative control group.Conclusion: Despite the restrictions in our study, the backfilling with GuttaFlow Bioseal in large apical diameter teeth may be beneficial in terms of fracture resistance.

“…The thickness of the apical plug was based on Bani et al, and Çiçek et al, studies and was determined as 3 mm for each specimen in the current study. The thickness of apical plugs ranging between 3 to 6 mm exhibited an adequate sealing ability regardless of the tested materials in both studies [ 29 , 30 ]. Enzymatic glucose oxidase technique has become a preferred method for the evaluation of the sealing capacity of different materials [ 31 ] and the glucose leakage model used in this study isconsistent with the model described by XU et al, [ 26 ].…”

There are limited data regarding the potential effect of erbium, chromium: yttrium–scandium–gallium–garnet (Er,Cr:YSGG) laser-activated irrigation (LAI) on the microleakage qualities of calcium silicate-based cements. The objective of the present study was to assess the effect of LAI on the microleakage qualities of MTA Repair HP (MTA-HP) and NeoMTA Plus (Neo) used in root-end filling and to compare the antimicrobial effectiveness of MTA- HP. Two experimental sets were conducted: antimicrobial activity (agar diffusion test/at 24, 48 h) and microleakage (glucose leakage model/at 1st, 10th, 20th days). Antimicrobial activities of MTA-HP, Neo, Biodentine, ProRoot and MTA Angelus were evaluated, and inhibition zones were observed not only against a range of Gram-positive and Gram-negative bacteria but also against yeast at 48h. For microleakage evaluation, fifty teeth were prepared to simulate the clinical situation where the root-tips (apex) are open, and randomly divided into two experimental groups (n = 20/group) according to the cement type (MTA-HP and Neo), and two control (n = 5/group) groups. Each experimental group was further divided into two subgroups (n = 10/group) with respect to LAI: MTA-HP, L-HP, Neo, L-Neo. A statistical difference was only detected between Neo and L-HP groups on day 1. Subsequently, MTA-HP exhibited superior microleakage quality compared to Neo in the short-term. Er,Cr:YSGG laser-activated irrigation could be used as a reliable technique without creating adverse effects on the sealing abilities of MTA Repair HP and NeoMTA Plus.

“…Access cavities were prepared in the remaining 36 teeth and the root canals were prepared from coronal to apical direction with peeso drills between #1 and #5 at 1 mm beyond the apex. Thereafter, a size 6 peeso reamer was used to extend the preparation of the canal 3 mm below the cementoenamel junction to approximate Cvek’s stage 3 of root development as described by Cicek et al 13 2.5% NaOCl was used during preparation of root canals. For final irrigation root canals were irrigated with 5 mL of 17% EDTA and 10 mL of distilled water and then dried with paper points.…”

Background. Regenerative endodontic treatment (RET) is a clinically advanced procedure for necrotic immature teeth. However, root canal walls of these teeth are brittle especially in the cervical region and need reinforcement. This in vitro study is conducted to evaluate the effect of intra-orifice barrier materials on the fracture resistance of immature teeth treated with regenerative procedure. Methods. Forty-eight maxillary central incisors were used. Twelve intact teeth were selected for the control group. Remained teeth were prepared using peeso drills to simulate immature teeth and assigned into three groups according to the intra-orifice barrier material placed over MTA (n=12); Composite resin (CR), ProRoot MTA and Resin-modified glass ionomer cement (RMGIC). Fracture strength test was applied using a universal testing machine. One-way ANOVA and Tukey post hoc tests were used at P=0.05. Results. A significant difference was obtained among groups (P<0.05). MTA showed the lowest fracture resistance (P<0.05). However, no significant difference was found among RMGIC, CR, and control groups (P>0.05). Conclusion. Intra-orifice restorative materials have reinforcement affect in immature teeth treated with regenerative endodontic procedure. RMGIC or CR can be regarded as a viable choice to reduce the occurrence of cervical root fracture of immature teeth treated with a regenerative therapy.
