A comparative evaluation of sealing ability of three perforation repair materials using a field emission gun-scanning electron microscope

Introduction: The study aimed to assess the sealing ability of Biodentine™, ProRoot mineral trioxide aggregate (MTA), and Super-EBA as furcation perforation repair materials using field emission gun-scanning electron microscope (FEG-SEM). Materials and Methods: Thirty-six extracted human permanent mandibular molar teeth were collected and cleaned. Standard access cavity preparation was made, and intentional perforation was created in each of the access cavity-prepared teeth using #12 round bur. The teeth were randomly divided into three groups each containing 12 teeth. The perforations were sealed as follows: Group A with Biodentine™, Group B with ProRoot MTA, and Group C with Super-EBA. The repair materials for all the three groups were evaluated for marginal adaptation using FEG-SEM. Data were statistically analyzed using one-way ANOVA and Tukey's honest significance test. Results: Quantitative FEG-SEM observations illustrated that the mean gap at the dentin–furcation repair material interface was as follows: Biodentine (3.01 ± 0.37 μm), ProRoot MTA (4.98 ± 0.68 μm), and Super-EBA (8.03 ± 0.68 μm). The difference between Biodentine™ and ProRoot MTA was not statistically significant (P > 0.05). Individually, Biodentine and ProRoot MTA showed statistically significant differences when compared to Super-EBA (P Conclusion: The sealing ability of ProRoot MTA and Biodentine™ as a repair material of furcation perforation was better than Super-EBA.

Sealing ability of three different root repair materials for furcation perforation repair: An in vitro study.

Aim:The present study aimed to evaluate and compare the sealing ability of mineral trioxide aggregate (MTA)-Angelus, Biodentine™, and EndoSequence cement in furcation perforations using protein leakage assessment.Materials and Methods:The present study was conducted using seventy extracted human maxillary and mandibular molars with intact furcation.

Biodentine showed minimum (0.1201 mg/ml), MTA showed maximum (0.3738 mg/ml), and EndoSequence had intermediate (0.2465 mg/ml) leakage. None in the negative control and all of the positive control specimens leaked during the experimental period of 60 days.Conclusion:The newer biomaterials, Biodentine and Endosequence with better handling properties, could be used as alternatives to MTA-Angelus while repairing furcation perforations.

Conventional flap versus laser assisted periodontal surgery in the treatment of furcal abscess- a case report.

Introduction: Furcal perforations compromise the health of the periradicular tissues and threaten the viability of the tooth. Perforation repair is a very attractive and frequently successful alternative to extraction of the involved tooth. Diagnosis and repair of furcal perforation, abscess have remained a diagnostic and therapeutic dilemma for the clinician. We believe this case report is the first of its kind to compare the repair of furcal perforation due to iatrogenic causes with mineral trioxide aggregate (MTA) and bone graft by conventional surgical technique and laser assisted periodontal therapy in mandibular molars. Case presentation: Two patients presenting with clinical presentation and diagnosis of furcal abscess due to iatrogenic causes were treated and followed up for six months. The furca were exposed surgically. The furcation area in one patient was debrided by conventional periodontal therapy while in the other laser assisted periodontal therapy was instigated using diode laser, and the perforation sealed with mineral trioxide, bone graft was placed in the interradicular area. Clinical and radiographic examinations were conducted at base line and 6 months. Conclusion: During the 6 month follow up satisfactory resolution of the clinical and radiographic defect in the interradicular region was achieved by both conventional surgical and laser assisted periodontal therapy. Keywords: furcal abscess, perforation repair, mineral trioxide, diode laser, bonegraft

Evaluation of Furcal Perforation Repair in Primary Molars With MTA Versus Bioceramics (A Randomized Clinical Trial)

Non-surgical Repair of Iatrogenic Furcal Perforation with Mineral Trioxide Aggregate: A Case Report

Perforations are significant iatrogenic complications of endodontic treatment and could lead to endodontic failure. The prognosis is generally excellent if the problem is well-diagnosed and repair is well-performed with a material that can provide proper sealing ability and biocompatibility. In this case report, the patient presented with the complaint of continuous dull pain in his right mandibular first molar tooth. The tooth was attempted for endodontic treatment and perforation has occurred at that time. Radiographic examination revealed, destruction in the furcal area with a little radiolucency and periradicular lesion involving apical region of the roots. Considering the above conditions, endodontic treatment and nonsurgical repair of furcal perforation with mineral trioxide aggregate followed by permanent restoration was planned and performed successfully. Follow up after one month, the patient was symptomless and the affected area was found healthy. However, long term clinico- radiographic follow-up is essential.

Comparative evaluation of sealing ability of calcium sulfate with self-etch adhesive, mineral trioxide aggregate plus, and bone cement as furcal perforation repair materials: An In vitro dye extraction study.

The aim of this study was to determine the sealing ability of three different materials mineral trioxide aggregate (MTA) Plus, bone cement, and calcium sulfate with self-etch adhesive (SEA) for the repair of furcal perforation, using dye extraction method. Forty-eight extracted human permanent first and second molars were included and randomly divided into four groups: Group 1, n = 12, negative control, perforation not repaired with any material, Group 2, n = 12, perforation repair material used, MTA Plus, Group 3, n = 12, perforation repair material used, calcium sulfate with SEA, Group 4, n = 12, perforation repair material used, bone cement. The teeth were then coated with two coats of clear nail varnish immersed in methylene blue dye for 24 h, kept in 65% concentrated nitric acid for 3 days. Dye leakage was measured with the dye extraction method using a spectrophotometer at 550 nm. The negative control showed the highest mean values of dye absorbance (1.45). Bone cement (0.94) came second. Calcium sulfate with SEA (0.58) and MTA Plus (0.32) had no significant difference in their dye absorbance values. Within the limitations of the study, MTA Plus showed the least microleakage followed by calcium sulfate with SEA which has shown promising results and can be used as an alternative followed by bone cement which showed the highest microleakage.

Comparison of the sealing ability of Endocem mineral trioxide aggregate and Endoseal mineral trioxide aggregate as a furcal perforation repair material under the operating microscope: An in-vitro study

Objective: The aim of this study was to compare the sealing ability of pozzolan-based mineral trioxide aggregate (MTA) (Endocem) cement and pozzolan-based MTA (Endoseal) when used to repair the furcal perforations in permanent molars using the stereomicroscope. Materials and Methods: The study sample comprised forty-three recently extracted permanent molars. These teeth were placed in a 5.25% sodium hypochlorite solution for 24 h and washed with tap water. Access cavities were made using a #5 round bur in high-speed handpiece. Perforations were made in the center of the floor of the pulpal chamber using a round bur. The teeth were randomly assigned into three experimental groups based on the material used to seal the perforation: Group 1 – control group, Group 2 – Endocem MTA group, and Group 3 – Endoseal MTA group. The packed materials were allowed to set for 24 h. The samples were sectioned longitudinally, and the extent of marginal adaptation was measured by stereomicroscope. Kruskal–Wallis test was used for statistical analysis using SPSS software. Results: The difference in the mean length of dye penetration between groups was statistically significant. The pair-wise comparison was done between the three groups using Mann–Whitney U-tests as post hoc analysis, which reveals the difference between Group 1 and Group 2 was statistically significant P Conclusion: Endoseal MTA showed more microleakage than Endocem MTA. Therefore, within the limitations of this study, we suggest that Endocem has the potential to be used as a perforation repair material rather than Endoseal MTA.

Capability of biodentine and the mineral trioxide aggregate mta sealing in furcal perforation repair. Literature review

Endodontic therapy seeks to maintain natural dentition's integrity in form function and aesthetics. Accidents during these procedures commonly occur which affect the prognosis of root canal treatment. A furcal perforation is a complication that refers to the mechanical or pathological communication between the pulp chamber and supporting ligament, in the lower area of the pulp chamber and leads to the worst result of the treatment. It can occur during the endodontic access or during the preparation of an intraradicular retainer, although it can also be due to caries lesions of root absorption. For long term success, perforations should be repaired as soon as possible with a biocompatible material any delay causes bacterial contamination and leads to complicated periodontal endodontic lesions. An ideal perforation repair material , should create an adequate seal, be biocompatible, not be affect by blood contamination, be a bactericide, radiopaque, induce bone formation and healing, induce mineralization, cementogenesis, facilite its manipulation and application. Various materials have been used to repair furcal perforations including MTA and Biodentine. The objective of this study is to carry out a review of the literature about the sealing capacity of MTA and Biodentine in the repair of furcal perforations. To reach this objective a bibliographic review is carried out in the leading odontological databases and magazines and articles are chosen according to their scientific validity their relationship with the topic and the year of publication wich stretches from 2009 to 2018.

SEALING ABILITY OF BIODENTINE AND SIMVASTATIN FOR REPAIR OF FURCATION PERFORATION USING DYE EXTRACTION METHOD

Aim: This study aimed to evaluate the sealing ability of Biodentine and Simvastatin for the repair of furcal perforation using dye extraction method. Materials and Methods: Thirty extracted permanent human mandibular first molars were selected. Access cavities were prepared in all first molars while perforations were made at the furcation areas of only twenty five molars. Grouping of samples was done as follows, Group 1 (n = 10) in which perforations were repaired with Biodentine™, Group 2 (n = 10) in which perforations were repaired with Simvastatin, Group 3 (n = 5) in which perforations were left unrepaired (positive control) and Group 4 (n = 5) in which no perforations were done (negative control). The sealing ability in four groups was evaluated using dye extraction method. Statistical analysis was done using One-Way ANOVA test to compare the mean values of the different groups then pairwise comparisons were performed using Tukey’s post-hoc test. Results: The highest dye absorbance was recorded for the positive control group (0.081 ± 0.013) while the lowest value was recorded for the negative control group (0.003 ± 0.002). The mean value of Biodentine group (0.025 ± 0.009) was significantly lower than Simvastatin (0.069 ± 0.011). Conclusion: Sealing ability of Biodentine is significantly better than Simvastatin in furcal perforation repair.

Immediate and Delayed Repair of 2 Sizes of Furcal Perforations in Dogs' Teeth Using Mineral Trioxide Aggregate Cement

IntroductionThis histologic study aimed to measure the morphometric and morphologic changes in periodontal tissue after immediate and delayed mineral trioxide aggregate (MTA) repair of 2 sizes of furcal perforations. MethodsThere were 72 premolars from 12 beagle dogs that were divided equally into 4 experimental and 2 control groups (n = 12). Experimental groups included immediate small (0.6 mm in diameter), immediate large (1.8 mm in diameter), delayed (30 days) small, and delayed large furcal perforation MTA repair. The control groups included negative (no furcal perforation) and positive (nonrepaired small and large furcal perforations) controls. After 3 months, tissue blocks were harvested and processed for histologic assessment. Morphometric analysis measured the thickness of periodontal ligaments (average, maximum, and minimum) in millimeters, the area of interest in square millimeters, and the area of healing tissue at the perforation site in square millimeters. Morphologic assessment consisted of 7 parameters for tissue inflammation, resorption, and repair. Histologic assessment was completed by 2 calibrated examiners who were blinded to the study group. ResultsMorphometric and morphologic measurements showed no significant difference between immediate and delayed MTA repair of small perforations and the negative control. The average thickness of the periodontal ligaments in delayed large perforations was 0.467 mm, which was significantly different from 0.294 mm in the delayed small perforations repair. The area of healing tissue in the positive control was 0.473 mm2, which was significantly different from 0.311 mm2 in delayed large perforation repair. ConclusionsWithin the study limitations, periodontal tissue responded more favorably to MTA repair of furcal perforation when it was placed in smaller perforations. The time of treatment became more critical as the perforation size increased.

Repair of iatrogenic furcal perforation with glass ionomer cement

This article has no abstract. The first 100 words appear below:A 28 year old male patient came to the outpatient Department complain-ing of discomfort on his lower right first molar tooth during mastication for one month. The patient also stated that he had received dental treatment on the lower right side three months back. Clinically, the tooth appeared sound but there was poor coronal filling of the affected tooth and the pocket depth was within normal range (Figure 1A,B). When the pulp vitality test was performed, it responded negatively. However, percussion pain was present. It seems that due to iatrogenic mishaps, chronic periodontitis could be developed in this case.

Biodentine for Furcation Perforation Repair: An Animal Study with Histological, Radiographic and Micro-Computed Tomographic Assessment.

Introduction:Biodentine has been scarcely studied as a furcation perforation (FP) repair material, mostly by in vitro methodologies. This animal study aimed to compare the histological responses, radiographic, and micro-computed tomographic (micro-CT) outcomes after FP repair with Biodentine or ProRoot MTA (MTA) in dogs’ teeth. Methods and Materials: Fifty teeth from five dogs were divided into 4 groups: MTA (n=20, FP repaired with ProRoot MTA), BDT (n=20, FP repaired with Biodentine), PC (n=5, positive control, FP without repair) and NC (n=5, negative control, without perforation). The animals were euthanized after 4 months. Histological assessment included inflammatory cell infiltration, hard tissue resorption, hard tissue repair, and cement repair in the furcation area. Immediate postoperative and 4 months follow-up radiographs were compared for radiolucency in the furcation region. The volume of extruded material was quantified using micro-CT images. Results:The tested materials showed equivalent radiographic response, together with similar hard tissue resorption and repair but, BDT group showed significantly less inflammation, lower volume of extruded material and higher cement repair than MTA group. Conclusion:The outcomes of this study, taken together with other favorable results in literature, are highly suggestive that Biodentine is a promising biomaterial to be used for FP repair.

Evaluation of bioceramics and zirconia-reinforced glass ionomer cement in repair of furcation perforations: An in vitro study.

Aim:The aim and objective of this study was to evaluate and compare the sealing ability of EndoSequence BC RRM-fast set putty, Proroot mineral trioxide aggregate (MTA), and Zirconomer in the repair of furcal perforation by measuring dye leakage under stereomicroscope.Methodology:A standard access cavity was made on forty-eight extracted mandibular and maxillary first molars followed by creating a furcal perforation in the center of the pulp chamber by using No. 4 round bur (creating a perforation of 2 mm diameter). Teeth were categorized into 4 groups containing 12 samples in each group based on material used for furcation repair. Group 1 – Endosequence BC RRM-fast set putty; Group 2 – Zirconomer; Group 3-MTA (positive control); Group 4 – negative control. All groups were covered with two layers of clear varnish except for 2 mm around the perforation region. All the teeth were immersed in 2% methylene blue dye for 48 h for dye penetration. Teeth were sectioned buccolingually using a diamond disk. The sectioned teeth were examined under stereomicroscope with ×10 magnification for dye penetration.Results:Endosequence showed less microleakage than MTA but not statistically significant. Zirconomer showed statistically significant higher microleakage.Conclusion:Endosequence and MTA showed less microleakage hence can be used as furcation repair materials. Due to higher microleakage, Zirconomer should be avoided as furcation repair material. Due to its favorable cost, ready availability, and almost similar outcome as bioceramics, MTA is considered as an alternative to Endosequence and is the gold standard in furcation repair.

Comparison of Push-Out Bond Strength of Furcation Perforation Repair Materials - Glass Ionomer Cement Type II, Hydroxyapatite, Mineral Trioxide Aggregate, and Biodentine: An in vitro Study.

Background:A furcation perforation is mid-curvature opening into periodontal ligament space which is a worst possible outcome in root canal treatment. Perforations should immediately be repaired with a biocompatible material to seal the communication between perforation site and gingival sulcus.Aim:The aim of this study was to evaluate the push-out bond strength of glass ionomer cement, hydroxyapatite, mineral trioxide aggregate, and biodentine (BD) when used in repairing furcal perforations with and without blood contamination in permanent molars.Materials and Methods:A total of 120 human extracted molars were collected and divided on the basis of perforation repair materials and blood contamination status (n = 15). All the materials were subjected to universal testing machine to a load cell from 0 N to 100 KN at a crosshead speed of 1 mm/min.Statistical Analysis:The data obtained were subjected to statistical analysis using SPSS version 20.0. Results andConclusion:The push-out bond strength was maximum in BD contaminated with blood and least for the hydroxyapatite contaminated with blood. A significant difference was found between all the perforation repair materials.

Animal models used in furcation perforation studies: A systematic review and comprehensive synthesis of model characteristics.

In order to systematise furcation perforation (FP) experimental animal models described in the literature and to determine whether there is evidence that a model is superior to others, MEDLINE/PubMed, SciELO and Cochrane Library were searched to find studies which used animal models of FP. Data were gathered concerning model characteristics, chosen groups, sample numbers, type of outcomes, journal and main area studied. Twenty-five articles were included in this systematic review, four conducted in rodent models, three in non-human primates and 18 in dogs. Medians were six animals and 34 teeth per study; 10 teeth per test group and, when performed, six teeth per control group. Twenty-four studies investigated the use of materials for FP repair; eight also tested adjuvant materials/substances. Although there is no model which can be described as ideal and superior than others for FP studies, dogs appear to possess the most suitable model characteristics.
