ABSTRACT Aim: This randomized clinical trial aimed to compare the effectiveness of mineral trioxide aggregate (MTA), Biodentine, platelet-rich fibrin (PRF) with MTA, and PRF with Biodentine as pulpotomy medicament in the permanent molars with symptomatic irreversible pulpitis clinically and radiographically. Materials and Methods: Sixty permanent first molars with a carious exposed tooth showing signs and symptoms of irreversible pulpitis with caries extending >2/3 rd of dentin, but no signs of pulpal necrosis, were randomly allocated in four groups, and full pulpotomy was performed using MTA, Biodentine, PRF with MTA, and PRF with Biodentine as pulpotomy agents. The clinical and radiographic assessment was done after 24 h, 3 months, 6 months, and 9 months postoperatively. Nonparametric tests, including Kruskal–Wallis, Friedman test, and Chi-square test, were used for repeated measures among the biomaterials. For pair-wise comparison of subgroups, the Wilcoxon sum-rank test was used. Results: The clinical success rate was 90.5% at a 9-month interval. There was a nonsignificant result among all the groups ( P < 0.05), and all agents were equally effective in providing pain relief at all the intervals tested. No significant difference was observed between the radiographic success rates observed among the groups ( P = 0.089 at 6 months and P = 0.095 at 9 months). Conclusion: Pulpotomy dressing agents used proved to be a success in mature permanent teeth with carious exposure with clinical signs and symptoms of irreversible pulpitis.

ABSTRACT Aim: The aim of the study is to evaluate and compare the efficacy of glycolic acid (GA), phytic acid, chitosan nanoparticles, and ethylenediaminetetraacetic acid (EDTA) for the removal of intracanal calcium hydroxide (Ca [OH] 2 ) dressing using needle irrigation and passive ultrasonic irrigation (PUI). Materials and Methods: Seventy-two mandibular premolars were decoronated and roots were prepared to apical size 30. Ca(OH) 2 paste was filled in the canals and samples were stored for 1 week after which they were irrigated using different irrigants and irrigation techniques. The residual Ca(OH) 2 was analyzed on split surface of samples under stereomicroscope and scanning electron microscope. Scoring was done for each sample and results were tabulated. The data were subjected to analysis using Mann–Whitney U-test with the level of significance set to 5%. Results: Removal of Ca(OH) 2 was maximum in chitosan group aided by PUI and was minimum when GA or EDTA was used for needle irrigation, as observed under stereomicroscope. Removal of Ca(OH) 2 from the coronal third was maximum followed by middle and then apical third. Phytic acid and chitosan were proven to be of maximum efficacy for removal of intracanal Ca(OH) 2 removal in the middle third among all the groups, especially when used with PUI. Needle irrigation using EDTA and GA was least efficacious. Conclusion: Chitosan and phytic acid can be used for better removal of Ca(OH) 2 dressing, especially in the coronal and middle thirds of the root canal. The efficacy of intracanal dressing retrieval can be enhanced by passive ultrasonic activation.

Aim: Caries or traumatic injuries affecting young permanent teeth during root development usually result in an open apex which is highly challenging to treat. The aim of this study was to evaluate the push-out bond strength of apical plugs of Mineral Trioxide Aggregate (MTA) Plus, Biodentine, and calcium-enriched mixture (CEM) after premedication with chlorhexidine, triple antibiotic paste (TAP), and calcium hydroxide. Methods: Fifty-four extracted intact anterior teeth were decoronated and 3 mm was sectioned from the apex. The canals were rendered parallel using #80 K-files and #3, #4 Peeso reamers to mimic an open apex situation. The samples were divided into 3 groups containing 18 samples each for the three intracanal medicaments. After premedication, the samples were stored for 2 weeks at 37°C, following which the canals were cleaned using #80 K-file along with ethylenediaminetetraacetic acid and sodium hypochlorite irrigation. The samples were further divided into three subgroups, each containing six samples for the three calcium silicate cement used in this study. They were later subjected to push-out bond strength testing. Results: Regardless of the type of intracanal medicament used, Biodentine had significantly higher bond strength than MTA Plus and CEM. The highest push-out bond strength results were obtained in samples premedicated with chlorhexidine. Compared to TAP and calcium hydroxide (Ca(OH) 2), this value was statistically significant (P < 0.001). Conclusion: Within the limitations of this study, Biodentine showed the highest push-out bond strength as compared to MTA Plus and CEM. Chlorhexidine may be superior to calcium hydroxide and TAP medicaments when used for apexification procedures with calcium silicate cement.

ABSTRACT Aim: The aim of the study was to evaluate the antimicrobial activity of 1% phytic acid and ethylenediaminetetraacetic acid (EDTA) incorporated with 0.2% of chitosan nanoparticles (Csnps) against Enterococcus faecalis ( E. faecalis ) by agar diffusion and biofilm model. Materials and Methods: Antimicrobial efficacy was evaluated in two stages: (i) agar well-diffusion method and (ii) biofilm model. E faecalis (American Type Culture Collection 29212) strain was subcultured and grown on the blood agar plates, followed by placement of test solutions in punched holes (5 mm diameter) and incubated for 24 h at 37°C as follows (n = 10): Group 1: normal saline (control), Group 2: EDTA, Group 3: EDTA +0.2% Csnps, Group 4: 1% phytic acid, and Group 5: 1% phytic acid + 0.2% Csnps followed by measurement of inhibition zone. For biofilm model, standardized dentin blocks were prepared from fifty human-extracted single-rooted premolars and sterilized and contaminated for 2 weeks by transferring 50 μl of bacterial inoculum to sterilized test tubes containing 1 mL of Mueller–Hinton agar broth (MHA) with alternate day replenishment of the broth. The specimens were cleaned and subjected to test solutions as mentioned above. Serial decimal dilutions were prepared, followed by inoculation on MHA plates and incubation for 24 h, accompanied by counting of the colonies per milliliter (colony-forming unit per milliliter). Results were statistically analyzed using one-way analysis of variance and Post hoc Tukey’s tests ( P < 0.05). Results: Phytic acid incorporated with Csnps exhibited a greater zone of inhibition and least colony count against E. faecalis biofilm compared to all groups. Conclusion: Combination of Csnps and phytic acid exhibits effective antimicrobial activity against E. faecalis .

ABSTRACT In our daily practice, we are confronted with calcified teeth which require special attention and care during endodontic treatment. Several etiologies have been incriminated in the presence of pulp calcifications, especially dental trauma and aging. Those calcifications can cause partial or complete pulp canal obliteration. Therefore, endodontic treatment of these teeth can be very risky and should be done by a specialist using ultrasonic tips and a microscope. This treatment requires more time and has a lower success rate compared to other cases. Lately, a technique combining the digital imaging and the cone-beam computed tomography (CBCT) is proposed to form an endodontic guide which allows any practitioner to access the canal more easily. The use of CBCT is important in the planning of the treatment of severely calcified teeth. The guided treatment has many advantages compared to the conventional approach. It is proved to be more precise, more conservative, and less time-consuming. It has a high success rate and reproducible results regardless of the experience of the practitioner. The purpose of this review is to gain a better understanding of the pulpal calcification process and its impact on the endodontic treatment and to give insight into the advantages of using the guided endodontic technique in comparison with the conventional treatment in treating severely calcified teeth.

Aims: The aim of the present study was to evaluate and compare the push-out bond strength of single and multiple fiber-reinforced posts cemented with dual-cure resin cement using total-etch and self-etch adhesive systems. Methods: Sixty single-rooted maxillary permanent incisors were decoronated and endodontically treated. Following post space preparations, the roots were divided into four groups (n = 15); Group 1: single fiber-reinforced composite post with the total-etching agent, Group 2: single fiber-reinforced composite post with the self-etching agent, Group 3: multiple pin posts with the total-etching agent, and Group 4: multiple pin posts with the self-etching agent and then cemented using dual-cure resin cement. The samples were then sectioned to obtain approximately 2-mm disks, and a push-out test was performed. Data obtained were statistically analyzed using analysis of variance, post hoc Tukey, and unpaired t-test. Results: The mean push-out bond strength values showed that Group 3 had significantly higher bond strength as compared to the other groups (P < 0.05). Conclusions: Dentapreg multiple pin posts with total-etching agents resulted in higher push-out bond strength as compared to single fiber-reinforced posts and self-etching agents.

Aim: The purpose of this study was to assess the canal shaping ability and reduction of Enterococcus faecalis (E. faecalis) by ProTaper Universal (PTU), ProTaper Gold (PTG), and Twisted File (TF) systems, using microcomputed tomography (μCT). Methods: Distobuccal canals of 36 extracted human maxillary molars were inoculated with E. faecalis American Type Culture Collection 29212 for 28 days. Thirty-three specimens (three excluded due to contamination) were randomly divided into three groups with 11 specimens in each group, according to the instrumentation system that was utilized: PTU, PTG, and TF. Sterile distilled water was used as the irrigant during preparation. Paper points had been used to collect samples from the root canals both pre- and postpreparation, and bacterial quantification was done to examine the bacterial reduction. Pre- and postinstrumentation μCT scanning of roots were done to analyze the shaping ability. Results: After preparation, all three techniques significantly lowered the amount of E. faecalis while also significantly increasing the canal volume (P < 0.001). Intergroup comparison of the % of bacterial reduction and uninstrumented area disclosed no significant differences (P > 0.05), whereas the increase in canal volume of the PTU was significantly higher than PTG and TF, and that of the PTG was significantly higher than TF. Conclusion: It may be concluded, within the constraints of this in vitro study, that PTG and TF had better shaping ability than PTU, whereas no difference was found in their ability to reduce bacterial load.

Sterile distilled water was used as the irrigant during preparation. Paper points had been used to collect samples from the root canals both pre- and postpreparation, and bacterial quantification was done to examine the bacterial reduction. Pre- and postinstrumentation μCT scanning of roots were done to analyze the shaping ability. Results: After preparation, all three techniques significantly lowered the amount of E. faecalis while also significantly increasing the canal volume (P < 0.001). Intergroup comparison of the % of bacterial reduction and uninstrumented area disclosed no significant differences (P > 0.05), whereas the increase in canal volume of the PTU was significantly higher than PTG and TF, and that of the PTG was significantly higher than TF. Conclusion: It may be concluded, within the constraints of this in vitro study, that PTG and TF had better shaping ability than PTU, whereas no difference was found in their ability to reduce bacterial load.","PeriodicalId":11607,"journal":{"name":"Endodontology","volume":"35 1","pages":"54 - 59"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42987630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The separation of the nickel-titanium (NiTi) rotary files is seen occasionally due to improper use and lack of technique, which results in improper cleaning and shaping of the root canals, compromising the treatment outcome. Various techniques have been introduced to either bypass or retrieve the separated instrument. The present case series highlighted a low-cost and straightforward alternative to retrieve the separated NiTi rotary instruments using a customized syringe and loop technique with the assistance of a dental operating microscope. Three cases of fractured instruments in different root canals were addressed, with the customized syringe and loop technique being used to retrieve the instruments successfully. This supports the use of a convenient, reliable, and cost-effective approach to managing fractured endodontic instruments without costly equipment or specific retrieval kits.

ABSTRACT Aim: Different approaches are used to determine the working length of the root canal. The current and most widely researched are the electronic apex locators (EALs). Since the early apex locators were developed in 1942, several generations had their qualities and shortcomings developed. Thus, a comparative evaluation of the accuracy of different generations of EALs in determining the correct working length: Systemic review and meta-analysis to analyze individual studies quantitively and draw conclusions on the best generation of apex locator currently used. Materials and Methods: A comprehensive search was conducted on different electronic databases and by manual search. Studies comparing third and fifth generations with fourth-generation apex locators were subject to strict inclusion criteria followed by data extraction and meta-analysis. Results: Following the meta-analysis, the accuracy is fifth>fourth>third generation of apex locators. Conclusion: Analysis of individual studies quantitatively will give a better understanding of which devices to use to accurately determine the working length.
