Comparison of Fracture Resistance of Primary Incisors Restored with Different Intracanal-Reinforcement Materials.

AimTo evaluate the effects of placing short posts made of different restorative materials on the fracture resistance of root canals in primary incisors of primary teeth.Materials and MethodsThe root canals of 40 extracted primary incisors were prepared and filled with Vitapex and randomly divided into five groups of 8 each. In Groups 1–4, a post space was created and filled with different restorative materials (Tetric® N-Ceram Bulk Fill, AeliteFlo, Filtek Z250 XT, and GC Fuji II LC® capsule), while Group 5 was kept filled with Vitapex as a control. Fracture resistance was measured using a universal testing machine at a 0.5-mm/min crosshead speed. The results were statistically analyzed and compared.ResultsThe highest fracture resistance was recorded for GC Fuji II LC capsules [439.82 N] and control [423.37 N], while the lowest fracture resistance was recorded for Tetric® N Ceram Bulk Fill (239.91 N). A multiple comparison test showed that the Tetric® N-Ceram Bulk Fill had a significantly lower average value than AeliteFlo (P = 0.030), as well as a significantly lower average value than GC Fuji II LC® capsule (P = 0.001), and a significantly lower average value than the control group (P = 0.002). Multiple comparison tests showed no significant difference between Tetric® N-Ceram Bulk Fill and Filtek Z250 XT (P = 0.39).ConclusionThe fracture resistance of primary incisor root canals differs according to the material used for the intracanal posts. Three-millimeter intracanal posts in the primary incisors showed the highest fracture resistance for the teeth restored with GC Fuji II LC capsules and the control.

Lesion Sterilization Tissue Repair (LSTR) Approach Of Non-Vital Primary Molars With A Chloramphenicol-Tetracycline-ZOE Antibiotic Paste: A Scoping Review

The study aimed to perform a systematic scoping review with the need of exploring the actual clinical applications of the chloramphenicol-tetracycline-ZOE antibiotic paste (CTZ) as a lesion sterilization tissue repair (LSTR) therapy agent. Following a scoping framework suggested by Arksey and O'Malley, relevant articles (randomized controlled trials, literature reviews, observational studies, in vitro studies, and clinical case-series reports) published over the last 15 years (in English, Spanish, or Portuguese languages) were identified and retrieved from five internet databases: PubMed, Embase/Ovid, Cochrane Library, Google Scholar, and EBSCO. By title and abstract screening and after removing duplicates, 11 articles were finally included in the present scoping review: five randomized/non-randomized clinical trials, five in vitro studies, and one case-series report. According to the collected information, there were no differences between CTZ paste and conventional pulpectomy, antibiotic pastes, and intracanal filling materials, considering the clinical, radiographic, antimicrobial activity, and periapical tissue biocompatibility outcomes. CTZ has shown excellent rates of clinical success and good radiographic results, with adequate antimicrobial effects; however, its biocompatibility has been put into doubt. Contemporary pediatric dentists should carefully consider the CTZ paste as an alternative endodontic approach for pulpally involved primary molars, with the advantages of being simple and fast, and taking into account the limitations of instrumental pulpectomy such as the microbiological and morphological complexity of primary root canals.

Treatment Modalities for Rehabilitation of Mutilated Primary Anterior Teeth

Early childhood caries commonly affects the primary maxillary anterior teeth, in which extensive post- endodontic rehabilitation has always been a challenge. This is due to the small size of the crown, relatively large pulp chambers, and the age of the child. The remaining inadequate sound tooth structure renders restorations more prone to fractures. Among the available treatment modalities which include extraction of the grossly destructed tooth structure, use of semipermanent crowns and intracanal posts, the posts can be used effectively, to restore the lost function and anatomy. They also enhance the quality of the final coronal restoration by providing additional support for retention. The available methods for intracanal reinforcement for anterior teeth include the metal posts fabricated using orthodontic wires, short composite posts fabricated directed in the primary root canal, prefabricated glass fiber posts and posts utilising polyethylene fibers (Ribbond). Recently certain advanced techniques such as the biologic dentin and zirconia have also come into use. The various advantages and disadvantages for these have been summarised in this review along with the standardised clinical protocol for their placement in the primary root canals. Various in-vivo and in-vitro studies have concluded that the glass-fiber short intracanal posts provide the most suitable esthetics, strength, elastic modulus, and resilience. However, further qualitative research is required to certify it as a standard treatment modality.

Canal Transportation and Volumetric Dentin Removal Abilities of Ni-Ti Rotary File Systems in Curved Primary Root Canals: CBCT Study

Current improvements in nickel-titanium (Ni-Ti) rotary file systems have created a paradigm shift in the root canal therapy of primary teeth. Therefore, it is necessary to perform a comprehensive evaluation regarding the efficiencies of newly manufactured instruments for different parameters. The current study was conducted to evaluate the abilities of RaceEvo, R-Motion, ProTaper Gold (PTG) systems in curved primary root canals with regard to the patterns of canal transportation and volumetric dentin removal by using cone-beam computed tomography (CBCT). Two experimental sets were designed following the determination of experimental groups by using pre- and post-operative CBCT data: canal transportation and volumetric dentin removal. The highest amount of canal transportation was significantly detected in the PTG group in comparison to RaceEvo and R-Motion groups. When the mean values of volumetric dentin removal data were analyzed across all groups, the PTG group again exhibited the significantly highest value of dentin removal volumetrically, compared to RaceEvo, R-Motion and manual instrumentation groups. It is possible to state that R-Motion and RaceEvo rotary systems could be used as reliable alternatives without causing adverse mechanical effects and maintaining the original root canal anatomy of curved primary root canal systems compared with PTG rotary systems and manual instrumentation, with a high diagnostic sensitivity of CBCT in pediatric endodontics when the alternative methods are not adequate.

Comparison of Shaping Ability between Continuous Rotary and Manual Instrumentations in Pediatric Endodontics

Objective: The aim of this in vitro study was to evaluate the efficacy of rotary EndoArt Ni-Ti Gold Pedo Kit and K-files in shaping ability, canal transportation, centering ability and instrumentation time in primary molars. Methods: For the study total of 30 extracted primary molars root with minimum 7mm root length were selected. Shaping of root canals in primary molars were done using the two systems, and CBCT and specialized software were used for scanning and analysis of pre-operative and post-operative to evaluate the groups for their shaping properties, apical transportation and preparation time in primary root canals. Results: No differences were found in canal transportation measures and instrumentation time between the two groups (p>0.05). The EndoArt group removed more dentin compared to K-file in all sides of the root curvature. The statistical differences were significant for coronal and middle third of the root (p<0.05). Conclusions: Under the conditions of this study, rotary EndoArt Ni-Ti Gold Pedo Kit provided more conical canals than K-files in primary teeth.

Comparison of Various Root Canal Filling Materials and Obturation Techniques for Primary Teeth Using Microcomputed Tomography

Aim: The aim of this study was to compare the effectiveness of different filling materials and obturation techniques for root canal obturation in primary teeth. Materials and Methods: Eighty maxillary primary incisors were included in this in vitro study. After biomechanical preparation, all samples were scanned using microcomputed tomography (micro-CT) and root canal volumes were calculated. Samples were grouped according to filling materials and obturation techniques, with ten samples in each group. The samples were filled with zinc oxide eugenol (ZOE) and Vitapex using four different obturation techniques (local anesthesia syringe, lentulo spiral, pastinject, and lentulo spiral–ultrasonic activation). After filling, samples were scanned a second time using micro-CT and root canal volumes were calculated. The statistical analysis was performed using SPSS version 24.0. Data were analyzed by Kruskal–Wallis and Mann–Whitney U tests. Results: When the ZOE and Vitapex were compared, it was observed that there were no significant differences between their postobturated volumes, percentage obturated volume (POV), internal void (IV), and percentage of internal void volume (PIV) ( P > .05). The local anesthesia syringe group had a significantly lower postobturated volume and POV, and a significantly higher IV and PIV for both filling materials than that by the other groups ( P < .05). There was no significant difference between the other obturation techniques ( P > .05). For the local anesthesia syringe group, postobturated volume and POV were significantly higher and IV and PIV were significantly lower with Vitapex than with ZOE ( P < .05). There was no significant difference between the other obturation techniques filled either with ZOE or Vitapex ( P > .05). Conclusion: Except for the syringe technique, no difference was observed between the ZOE and Vitapex materials. The syringe technique used in the primary root canal filling was less effective than the other techniques, which had similar efficacy, and in this technique, more effective canal filling was achieved with Vitapex.

Comparative Evaluation of Cleaning Efficiency and Apical Extrusion of Debris Using Two Pediatric Rotary Endodontic Files: An In Vitro Study.

Aim and objectiveApical extrusion of debris and cleaning efficacy in primary root canal treatment has not been well elucidated by using specialized pediatric rotary endodontic files. The purpose of this study is to compare the amount of apically extruded debris and cleaning efficacy during the preparation of primary molar root canals using Pro AF Baby Gold and Kedo-S pediatric rotary files.Materials and methodsTwenty extracted primary molar teeth were assigned randomly to two groups (n = 10 teeth for each group), injected with Indian Ink and instrumented using Kedo-S and Pro AF Baby Gold pediatric rotary files, respectively. The apically extruded debris was collected and dried in pre-weighed using Eppendorf tubes. The dry weight was calculated by subtracting the preoperative weight from the postoperative weight. The cleaning efficacy was evaluated after the diaphanization process. Statistics: Data were analyzed statistically using the independent sample t-test.ResultsThe amount of apically extruded debris was significantly less for the Pro AF Baby rotary files group compared to the Kedo-S rotary files group (p < 0.05). Cleaning efficacy was significantly better with Pro AF Baby Gold when compared to Kedo-S rotary files in the apical region of the tooth.ConclusionAll instruments caused apically extruded debris in primary teeth. Pro AF baby Gold files can be used with less apical extrusion of debris. Cleaning efficacy was shown to be better with the Pro AF Baby Gold pediatric rotary endodontic file.How to cite this articleRathi N, Jain SA, Thosar N, et al.

The sample in this study was P. gingivalis. Result: This study showed that the diameter of inhibitor zone against P. gingivalis was exists on concentration of 50% and 100%, their values are 10,216 mm and 13,023 mm. The positive control showed an average inhibition zone of 12.803mm. Conclusion: Pluchea indica leaves extract showed antibacterial effect against P.gingivalis at the concentration of 50% and 100%. The 100% concentration had the largest inhibition zone and was equivalent to positive control in inhibiting P.gingivalis.

The Trends of Endodontic and Prosthodontic Treatment by Postgraduate Students in University of Malaya

This study is aimed to provide an insight into the types of treatment carried out by postgraduate students in the past 10 years. A retrospective study was carried out between November 2019 and February 2020 by deriving data from postgraduate students’ clinical logbooks of three different cohorts of Master of Clinical Dentistry (Restorative Dentistry in Conservative Dentistry) in 2010, 2013 and 2016. This retrospective data was systematically extracted from the records and tabulated categorically using an Excel spreadsheet (Microsoft Office Excel 2019). A descriptive analysis was carried out to further evaluate the results. Overall, the types of treatment carried out in the field of endodontics and fixed prosthodontics has changed in the past 10 years. An increasing trend is seen in the placement of all ceramic crowns and primary root canal treatment procedures, while a decreasing pattern is evident for secondary root canal procedures and placement of dental bridges.

Evaluation of Quality of Endodontic Re-Treatment and Changes in Periapical Status

Background:The present study was conducted to assess quality of root canal (RC) filling before and after RC re-treatment.Materials and Methods:Two hundred and thirty-eight radiographs of failed endodontic treatment were assessed. The periapical status of the endodontic treatment was evaluated with periapical index (PAI) scoring system. PAI <3 showed absence and PAI >3 showed presence of periapical lesion.Results:There was a statistically significant increase in scores 1 and 3 and decrease in scores 2, 4, 5, and 6 after treatment (P < 0.05). PAI score >3 was seen in 37% before which decreased to 16% after endodontic retreatment. 34.6% obturation was homogenous and 65.4% was nonhomogenous before endodontic retreatment. After endodontic retreatment, 95.2% became homogenous and 4.8% nonhomogenous. The reason for endodontic failure was furcation in 2%, iatrogenic causes in 3%, loss of coronal seal in 16%, periapical pathology in 25%, and inadequate root filling in 54%.Conclusion:There was significant improvement and decrease in size of periapical lesions in re-endodontic cases as compared to primary RC treated teeth.

Root-end Surgery or Nonsurgical Retreatment: Are There Differences in Long-term Outcome?

IntroductionThe decision of which modality of secondary endodontic treatment to perform is multifactorial and clinician dependent. The literature surrounding the long-term survival of nonsurgical retreatment compared with surgical retreatment remains equivocal and warrants further investigation. This 7-year retrospective study seeks to compare the outcome of nonsurgical retreatments with that of root-end surgeries performed on teeth without prior nonsurgical retreatments. MethodsInsurance claims from 1021 teeth of 987 patients in the Delta Dental of Wisconsin database were analyzed from the years 2008–2017. Tooth survival was evaluated using Cox regression models, and the P value was set at .05. Survival time was considered from the time of completion of nonsurgical retreatment or root-end surgery to the time of an untoward event, which was defined as extraction after root-end surgery or extraction/root-end surgery after nonsurgical retreatment. Only procedures performed by endodontists were included in the analysis. ResultsThe survival rate of teeth that received nonsurgical retreatment was 90% after 2 years, 86.8% after 4 years, and 85% after 6 years. The survival rate of teeth that received root-end surgery was 93.7% after 2 years, 90.5% after 4 years, and 88% after 6 years. No statistically significant difference was found in the survival of nonsurgical retreatment compared with root-end surgery. Likewise, no statistically significant difference was found within or between tooth types (anterior, premolar, or molar) when comparing nonsurgical retreatment with root-end surgery. ConclusionsThe results of this study indicate that clinicians can choose either nonsurgical retreatment or root-end surgery after failed primary root canal therapy. Tooth location was not a determining factor in the survival rate after nonsurgical retreatment or root-end surgery.

Postoperative pain after ultrasonically and laser-activated irrigation during root canal treatment: a randomized clinical trial.

To compare the intensity of postoperative pain after primary root canal treatment of asymptomatic teeth when using ultrasonically (UAI) or laser-activated irrigation (LAI). In this superiority randomized clinical trial (ClinicalTrials.gov ID: NCT03981237) with parallel design, fifty-six patients with an asymptomatic tooth in need of primary root canal treatment were enrolled. After chemo-mechanical canal preparation using rotary instruments and NaOCl irrigation, teeth were randomly assigned to two groups and patients were blinded to the final irrigation protocol. In the UAI group (n=28), 60s activation with an Irrisafe tip was done per canal. In the LAI group (n=28), NaOCl was activated with a pulsed Er:YAG (2940nm) laser, equipped with a conical tip, with settings of 50µs, 20mJ at 15Hz for 60s. Patients recorded their pain intensity 6, 24, 48 and 72h after treatment on a 100mm visual analogue scale (VAS), as well as their analgesic consumption. Pain levels and incidence were compared across groups using the Mann-Whitney U-test and chi-square test. Overall, mean postoperative pain intensity was low, with the majority of patients having no or minimal pain 24h postoperatively. At 6h postoperatively, pain intensity and incidence were significantly higher in the UAI group compared to the LAI group (P<0.05). For the other time intervals, no significant differences in postoperative pain incidence or intensity were found. The frequency of analgesic intake did not differ significantly between the two groups. Neither of the activation methods resulted in any adverse effects. Ultrasonically and laser-activated irrigation resulted in low and comparable levels of postoperative pain in asymptomatic patients receiving primary root canal treatment.

Antibacterial Efficacy of Different Herbal Based Irrigant Solutions in Deciduous Teeth

Introduction: Endodontic infection requires the successful removal of microorganisms from the root canal system. The most effective irrigant solution is sodium hypochlorite, but possible problems due to its toxicity require the look for new alternatives. Constant increases in antibiotic resistance and side-effects caused by chemical irrigation have shifted research towards the production of herbal alternatives, especially in paediatric dentistry. Aim: To evaluate and compare the antibacterial efficacy of miswak, green tea, chamomile and 0.5% NaOCl as an endodontic irrigants against Enterococcus faecalis in primary root canals. Materials and Methods: The in-vitro study was conducted at the Department of Conservative Dentistry and Department of Microbiology, College of Dentistry, University of Duhok from January 2020 till June 2020. Seventy five freshly extracted intact human mandibular primary molars were decoronated at Cemento-Enamel Junction (CEJ) and distal roots were separated and biomechanically prepared up to F3 Protaper file and stored in normal saline. The specimens were inoculated with Enterococccus faecalis suspension and incubated for 72 hours. Specimens were divided into five groups containing fifteen teeth each (n=15). Freshly prepared alcoholic extracts of miswak, green tea and chamomile were used as an irrigant solution against E.faecalis compared to NaOCl as positive control and normal saline as negative control. Swabs were collected using F3 protaper paper points. The number of colonies was counted in suitable plate under good illumination and manual lens for magnification. Statistical analysis was performed by using Kruskal-Wallis one-way Analysis and Student-Newman-Keuls Method. Statistical Package for the Social Sciences (SPSS) version 26.0 was used. The p-values more than 0.05 were considered as statistically non significant. Results: Green Tea, among the herbal experimental groups, had the most effective antibacterial effect against E.faecalis. No significant statistical difference was detected between green tea (p=0.272) and NaOCl; however, there was significant difference between miswak, chamomile and NaOCl as well as between the rest herbal experimental groups and normal saline. Conclusion: NaOCl remains the gold standard as irrigant in primary teeth. Green tea extract may help in reducing E.faecalis inside the canals of primary teeth. Good efficacy against E.faecalis was also shown by Miswak and chamomile however the results obtained were not significant when compared with NaOCl.

Postoperative Quality of Life after Single-Visit Root Canal Treatment Performed with Reciprocating Shaping Systems: An Observational Study

Postoperative pain is a frequent complication of root canal treatment. It could worse patients’ quality of life (QoL) and it may be associated to several factors, including the shaping technique. The aim of the study was to compare the impact of WaveOne Gold (WOG) and WaveOne Classic (WOC) reciprocating instrumentation on postoperative QoL after single-visit primary root canal treatment. Healthy subjects with pulp necrosis on multirooted teeth were observed. Canal shaping was performed with WaveOne Gold Primary (n = 25) or WaveOne Classic Primary (n = 29) and canal filling was completed with a carrier-based technique. Mean and maximum scores for postoperative pain were assessed through a Visual Analogue Scale (VAS) and QoL indicators were evaluated with a self-assessment questionnaire based on a Likert scale. Postoperative pain curves were similar in both groups (mean pain p = 0.43; maximum pain p = 0.27) and quality of life indicators showed no significant differences (p &gt; 0.05). There was a more favourable trend of QoL values in the WOG group, reaching statistical significance on day six posttreatment (p = 0.021). Within the limitations of the study, reciprocating instrumentation may have an impact on patients’ QoL, but the innovative geometrical and alloy properties of the WaveOne Gold seemed to induce a faster resolution of the postoperative symptoms.

Bacteria and virulence factors in periapical lesions associated with teeth following primary and secondary root canal treatment.

This cross-sectional study aimed to investigate the microbial profile and to quantify the levels of endotoxins (LPS) and lipoteichoic acid (LTA) present in periapical lesions associated with root filled teeth and those that had received root canal retreatment. It also aimed to investigate the association between microorganisms and their virulence factors with clinical and radiographic features. Patients with periapical lesions in teeth with post-treatment endodontic disease following primary root canal treatment (n=19) and unsuccessful root canal retreatment (n=13) were treatment planned for endodontic microsurgery, where the periapical lesions were collected. Clinical and radiographic data were also collected. For microbiological analysis, nested polymerase chain reaction was used to detect 17 bacterial species. Levels of LPS and LTA were determined using limulus amebocyte lysate and enzyme-linked immunosorbent assays, respectively. The Student t-test or Wilcoxon-Mann-Whitney tests were applied to compare the data on LPS and LTA with clinical and radiographic features. The associations between the clinical and radiographic features and the bacterial species were analysed using the Fisher's exact test. A significance level of 5% was adopted. Bacterial DNA, LPS and LTA were detected in all samples. Parvimonas micra was the most commonly detected species in all groups, followed by Enterococcus faecalis, Fusobacterium nucleatum and Porphyromonas endodontalis. The type of endodontic treatment, whether a primary root canal treatment or retreatment, was not associated with the presence of any bacterial species in periapical lesions. The levels of LPS and LTA in periapical lesions of root filled teeth were not significantly different from those that had been retreated. Associations between the levels of LPS and LTA with clinical signs and symptoms were found. No association was found between specific bacteria and clinical features. Periapical lesions associated with teeth after primary root canal treatment and retreatment had similar polymicrobial composition. The levels of LPS and LTA in periapical lesions associated with teeth after primary root canal treatment and retreatment were similar, and both were associated with the same symptomatology.

Comparative Analysis of Root Canal Filling Debris and Smear Layer Removal Efficacy Using Various Root Canal Activation Systems during Endodontic Retreatment.

Background and objectives: The complete removal of obturation material can be a challenge in nonsurgical root canal retreatment. The insufficient removal of obturation material is a reason for root canal retreatment failure. Materials and Methods: The purpose of this study was to assess the efficacy of different final root canal irrigation activation methods in removing debris and smear layers in the apical and middle portions of root canals during retreatment. Sixty-six distal roots of freshly extracted molars were randomly divided into six groups: (1) primary root canal treatment with no obturation (negative control); (2) retreatment with only conventional instrumentation and irrigation (positive control); (3) retreatment with additional ultrasonic irrigation using the Piezon Master 700; (4) ultrasonic irrigation with the ENDOSONIC Blue; (5) sonic irrigation with the EDDY; and (6) multisonic irrigation with the GentleWave system. Roots were split and prepared for scanning electron microscopic (SEM) evaluation. Acquired images were assessed to quantify the amount of debris and smear remaining. Results: Among the treatment groups, Group 6 had a significantly lower debris score than Group 2 (positive control) in both the middle and apical regions (p = 0.004, p = 0.012). All treatment groups showed significantly lower smear scores than Group 2 in the middle and apical regions (p < 0.05). Conclusions: The GentleWave multisonic System showed a more optimal cleaning efficacy of the root canal debris but did not differ significantly with the tested passive ultrasonic or sonic irrigation method.

An Observational Study on the Materials and Techniques Commonly Adopted by Pediatric Dentists for Single Visit Pulpectomy

The outcome of an endodontically treated primary tooth is affected not only by the biomechanical root preparation and disinfecting solutions, but also by the biocompatibility and resorbing properties of the obturating materials used through techniques that provide adequate fill and adherence of the material. The aim of the study is to recognise the most preferred obturating material and technique used by pediatric dentists for single visit pulpectomy. A total of 2496 pulpectomy procedures were obtained by reviewing case sheets and were analysed using descriptive statistics on SPSS Software. Among 2496 procedures, 96.6% utilised Metapex as the obturating material and 77.5% employed condensation technique for obturation. Metapex was the most common obturating material used and condensation technique was the preferred technique by which primary root canals were filled by pediatric dentists for single visit pulpectomy.
