Interdisciplinary Management of Maxillary Canine Buccal Ectopia Associated with Peg Shaped Lateral Incisor
Aligning a displaced maxillary canine into the dental arch is one of the most complicated problems in orthodontics. In cases of extremely high displacement, the tooth is frequently removed surgically. Because of the upper canines’ significance to dental esthetics and functional occlusion, such a decision is a very serious one. The purpose of this report is to illustrate an interdisciplinary approach involving both orthodontic management and conservative tooth restoration. The case was treated through an orthodontic nonextraction fixed appliance mechanotherapy for successful alignment of buccally ectopic upper left canine followed by a conservative direct composite tooth buildup of peg lateral incisor associated with the upper left ectopic canine in a 16-year-old adolescent North Indian female. Posttreatment records demonstrated good alignment of the displaced tooth and restoration of normal anatomy of the peg shaped lateral incisor

Comparative evaluation of the fracture resistance of three different recent composite systems in large class II MOD cavities: An in vitro study
Background: For severely mutilated teeth, this research evaluated the most contemporary restorative material. Aim: Repair of Class II MOD cavities in premolars with Ever X posterior in the recent past, Beautifil restorative, and the Universal TetricEevoCream composite systems will be evaluated and compared in this research. “Materials and Methods:” Sixty human maxillary premolars were chosen for the study. As a check, we utilised a group of fifteen healthy teeth (Group 1). The remaining 45 teeth were fitted with MOD cavities of standardised dimensions and randomly assigned to one of three groups (Groups 2, 3, and 4) (n = 15). They used Beautifil restoratives for teeth in Group 2, GC Ever X posterior for teeth in Group 3, Universal Tetric EvoCream for teeth in Group 4. Newtons were used to measure the strength of a material (N). Results: Group 4 exhibited the greatest mean fracture resistance of the four groups, followed by Groups 3, 1, and 2 and finally Group 4. Conclusion: It was found that the Universal Tetric EvoCream composite had the greatest fracture resistance among the test groups. There was a substantial statistical difference between all of the groups.
 
The effect of irrigating solutions on the apical sealing ability of MTA Fillapex and Adseal root canal sealers
Background. Maximum sealing ability or adhesion of endodontic sealers can be achieved after effective removal of the smear layer. Endodontic irrigants assist in adequate removal of the smear layer, improving the retention mechanism. The aim of this study was to evaluate the effect of two different root canal irrigation solutions (5.25% NaOCl followed by 17% EDTA and QMix) on the apical sealing ability of two different root canal sealers (MTA Fillapex and Adseal). Methods. Forty-six single-canal teeth were divided into 4 experimental groups of 10 teeth each and a positive and negative group of 3 teeth each. The root canals were prepared using step-back technique. The teeth in groups 1 and 2 were irrigated with 5.25% NaOCl followed by 17% EDTA and the teeth in groups 3 and 4 were irrigated with QMix. Finally all the teeth were flushed with sterile saline and dried using paper points. Obturation was accomplished by gutta-percha using lateral condensation technique. MTA Fillapex sealer was used in groups 1 and 3 whereas Adseal was used in groups 2 and 4. Dye penetration method was used to evaluate apical leakage. Data were analyzed with Kruskal-Wallis and Mann-Whitney U tests using SPSS 14. Statistical significance was set at P < 0.05. Results. Group 3 showed maximum amount of apical leakage (3.7±0.3 mm) whereas group 2 exhibited the least amount of apical leakage (2.1 ± 0.4 mm) among all the experimental groups. Significant differences were found in the amount of apical leakage between all the groups (P = 0.00001). Conclusion. Within the limitations of this study, 5.25% sodium hypochlorite followed by 17% EDTA and Adseal resulted in the best apical seal

Background : The purpose of this study was to evaluate apical debris extrusion in curved root canals using a specific file system.METHODS:50 human mandibular molars were extracted and chosen for the study, ranging between 20 and 40 degree and curvature radii <10mm were randomly assigned to 2 groups (n=20) according to the kinematics used for root canal preparation ( reciprocating motion with waveone gold reciprocating system) and the Manual Technique. The apically extruded debris were collected in eppendorf tubes. The tubes are stored in an incubator for 5 days. The time recorded for each instrumentation procedure was recorded. Results: The Wave One Gold reciprocating system is associated with less extrusion of debris as compared to Manual technique. Conclusion : Under the conditions of the study both the Wave One Gold Reciprocating system and the Manual instrumentation technique caused apical debris extrusion to some degree. The WaveOne Gold reciprocating system caused less extrusion of debris in curved root canals compared with manual instrumentation technique
Impact of laser disinfection and passive ultrasonic irrigation on postoperative pain in single visit root canal therapy
Introduction: Postoperative endodontic pain is common. 3 to 58% of patients had post-op pain. Canal microbes are tough to eliminate. No irrigant meets all the perfect irrigant characteristics. Methods: In Kanpur, India, 46 participants were enrolled in this randomised clinical trial from January to June 2022. Department of Conservative Dentistry and Endodontics conducted the study. Local anaesthetic (1:2,000 lignocaine with adrenaline) was followed by rubber dam isolation and access cavity preparation. Teeth were cleaned and shaped. Patients were divided into two groups using a coin flip. Group A employed a 2 W 810 nm diode laser for laser disinfection. In Group B, sodium hypochlorite (NaOCl) was ultrasonically agitated. After a final treatment with saline, composite resin was used for obturation and post-endodontic restoration. A blinded assessor rated post-endodontic treatment after 6 hours, 24 hours, 48 hours, and 7 days. SPSS 20.0 was used to gather and analyse the data after utilising Pearson's Chi-square test with 5% significance. Results: 25 men and 19 women among 44 patients. 10 patients were 40-60, 28 were 30-40, and 12 were 18-29. No statistically significant difference was seen between PUI and laser disinfection in single visit root canal therapy (p=0.086). 
Assessing fracture resistance of endodontically treated teeth obturated with four different root canal sealers: An in-vitro study
Background: This study aims to evaluate fracture resistance on endodontically treated teeth when four unique sealers are being used. Materials and Methods: 75 human premolars (mandibular) recently extracted were utilised for this analysis. Random categorization of selected samples into 5 different groups depending on the type of sealer applied in the canal. Group 1: RCTpex sealer, Group 2: MTA Fillapex sealer, Group 3: Seal-Pex sealer, Group 4: Traditional zinc oxide-eugenol sealer, Group 5: Control (un-obturated tooth). Universal testing equipment (IIT, Kanpur) was used to assess fracture force after the teeth were inserted in acrylic cubes. Statistical analysis used one way ANOVA and test of post-hoc. All the groups had significant findings (P < 0.05) statistically. Results: Groups one and two presented more excellent fracture endurance as compared to other groups. Furthermore, there was no noteworthy difference between group three and four or group four and five statistically. Conclusion: The group of resin sealer was found to be more successful than other groups in this in vitro study. The ZOE sealer group and the control group, however, showed no significant differences
Impact of endodontic access cavity design and thermo-cycling on fracture strength of root canal treated mandibular molar teeth: An ex-vivo study
Aim: Aim of study is to evaluate the fracture resistance of the root canal treated Mandibular 1st and 2nd molar teeth with Conventional(TEC) access design and Truss(TREC) access design restored with composite resin and subjected to thermocycling. Method: 60 human 1st and 2nd molar (mandibular) teeth were randomly categorised into six (6) groups: CON (GroupI), TEC (GroupIII), TREC(GroupV) not subjected to thermocycling whereas CONTC (GroupII),TECTC(GroupIV) and TRECTC(GroupVI) subjected to thermocycling. Biomechanical preparation of the canals were done upto #F3 of Protaper gold rotary files (Dentsply) and obturated using gutta-percha points and restored using SDR bulk-fill composite(Dentsply). All samples were then subjected to thermo-cycling for 5000cycles between 15°C and 45°C for different time intervals and their fracture toughness tested under an Universal Tester with steel ball of diameter 5mm at a constant 1mm/min speed. Two-way and one-way ANOVA test employed for statistical analysis. Result: The fracture strength of teeth in TREC group had no notable variation with the control group (P>0.05) without thermocycling. Both TEC and TREC designs notably reduced the fracture toughness after thermocycling (P<0.05). The least fracture resistance was noted in TECTC group. Conclusion: TREC ought to increase the fracture resistance of root canal treated teeth after thermocycling
Comparative evaluation of root filling after obturation with gutta-percha and 3 different sealers of minimally instrumented root canals of the maxillary second molar
Introduction: The purpose of this study was to compare the superiority of root fillings made with three different sealers after minimal instrumentation of maxillary Second Molar root canals utilising a modified single-cone method. The specimens were separated into three groups and filled with a size-fit gutta-percha master cone and Sealmax-R (MAARC), Ah Plus (Dentsply), and MTA Plus (PrevestDenpro) sealers. Before and after instrumentation, post-Gentle Wave, and after obturation, micro–computed tomographic images were collected. Starting at the top of the root, the mesiobuccal roots of the selected teeth were sectioned in 0.5-mm intervals. Light microscope was used to examine the cross sections. Results: In all three groups, was filled to 90%–99% of the canal space. Sealmax-R and Ah Plus groups used more filler material on average than MTA Plus group (P <.05). Apical, middle, and coronal thirds showed no significant differences. Cross-sectional scans indicated no obvious gaps in the Sealmax-R groups. After instrumentation, hard tissue debris was discovered in the root canal system in 49 of the 189 canal thirds (25.9%). After Gentle Wave cleaning, only 4 of 63 canals (6.3%) and 4 of 189 canal thirds (2.1%) contained debris
