Comparative Evaluation of Fracture Resistance of Endodontically Treated Teeth Instrumented With K3XF Rotary Files Using Different Tapers.

Aim: To compare the effect of different tapers of the K3XF file system on the fracture resistance of endodontically treated mandibular premolars obturated with a three-dimensional (3-D) obturation system.

Methodology: For the study, 80 freshly extracted human mandibular premolars with single well-developed roots without any curvatures were taken and the tooth roots were wrapped in a single layer of aluminum foil, and they were placed vertically in a plastic mold filled with self-curing acrylic resin. The access was opened, and working lengths were determined.

Comparative Evaluation of the Percentage of Gutta-percha Filled Areas in Canals Obturated with Different Obturation Techniques.

Aim: To evaluate the percentage of gutta-percha filled areas (PGFA) in canals obturated with guttacore system, single cone, and lateral compaction techniques.

Materials And Methods: A total of 60 single-rooted mandibular premolars were selected and randomly divided into three equal groups depending on the type of obturation technique used. After the obturation, the samples were marked at 2, 4, 6, and 8 mm distance from the apex and sectioned horizontally, and viewed under a stereomicroscope at 25×.

The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of silver nanoparticles against .

Aim: To determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of silver nanoparticles against . The antimicrobial efficacy of the silver nanoparticles was determined by the standard methods of Clinical and Laboratory Standards Institute (CLSI). Different concentrations of silver nanoparticles were prepared, and MIC was calculated by tube macro-dilution method.

Effect of post space preparation on the sealing ability of mineral trioxide aggregate and Gutta-percha: A bacterial leakage study.

Aim: The purpose of this study was to evaluate the effect of post space preparation on the sealing ability of teeth obturated with mineral trioxide aggregate (MTA) and Gutta-percha.

Materials And Methods: Fifty intact human mandibular premolars, after decoronation and biomechanical preparation, were randomly divided into three experimental groups. In Group A (n = 10), the canals were obturated with Gutta-percha using cold lateral compaction technique, followed by immediate post space preparation.

Comparative Evaluation of the Effects of Light Intensities and Curing Cycles of QTH, and LED Lights on Microleakage of Class V Composite Restorations.

Background: The purpose of this study was to evaluate the effects of light intensity and curing cycles of QTH and LED lights on the microleakage of Class V composite restorations.

Materials And Methods: Eighty freshly extracted human maxillary premolars were used for this study. Standardized Class V cavities were prepared and they were restored with microhybrid resin composite.

Endodontic management of mandibular second molar fused to a supernumerary tooth, using spiral computed tomography as a diagnostic aid: a case report.

Fusion is a developmental anomaly characterized by the union of two adjacent teeth. In this paper we report a rare case of fusion involving permanent mandibular second molar with supernumerary tooth. The rarity with which this entity appears, along with its complex characteristics, often makes it difficult to treat.

A conservative single visit reattachment of fractured crown fragment.

Injury of anterior teeth is a relatively common event that mainly affects children and adolescents. Dentists are confronted with managing dental trauma and restoring fractured teeth on a regular basis. Hence the techniques that speed and simplify the treatment, restore esthetics and improve long term success rate are considered of potential value.

Endodontic and esthetic management of maxillary lateral incisor fused to a supernumerary tooth associated with a talon cusp by using spiral computed tomography as a diagnostic aid: a case report.

The aim of this case report is to present an endodontically and esthetically managed maxillary left lateral incisor fused to a supernumerary tooth associated with a talon cusp. This case report describes a multidisciplinary approach involving endodontic and restorative considerations for a successful, functional, and esthetic rehabilitation of the fused tooth. In the present case, we have used spiral computed tomography for better understanding of the complicated root canal morphology of the fused tooth and successful management of this rare case.

Management of a patient with a taurodont, single-rooted molars associated with multiple dental anomalies: a spiral computerized tomography evaluation.

Anomalies, though rare, are potential restorative and endodontic challenges. This case report presents a unique case with a bizarre combination of anomalies, including single conical unbifurcated posterior root forms, taurodontism, dens invaginatus, prominent labial lobes of the canines, pyramidal cusps of the premolars, dens evaginatii of the molar crowns, and localized reduction in tooth size involving the entire dentition without any other apparent systemic complication. On literature review, only 4 such cases were found to be reported.

Evaluation of fracture resistance in simulated immature teeth using Resilon and Ribbond as root reinforcements--an in vitro study.

Background/aim: To compare the reinforcement and strengthening ability of resilon, gutta-percha, and ribbond in endodontically treated roots of immature teeth.

Material And Methods: Sixty five freshly extracted human maxillary anterior teeth were prepared with a Peeso no. 6 to simulate immature teeth (Cvek's stage 3 root development).

Single-step apical barrier placement in immature teeth using mineral trioxide aggregate and management of periapical inflammatory lesion using platelet-rich plasma and hydroxyapatite.

We present here a case report of a tooth with an immature root with a large periapical lesion. The open apex was managed by placing an apical barrier using mineral trioxide aggregate, and the periapical lesion was treated surgically. A combination of platelet-rich plasma (PRP) and hydroxyapatite graft (HA) was used to achieve faster healing of the periapical lesion.

Invasive cervical resorption: a case report.

Invasive cervical resorption (ICR) is a relatively uncommon form of external resorption, which may occur in any tooth in the permanent dentition. Characterized by its cervical location and invasive nature, this resorptive process leads to progressive and usually destructive loss of the tooth structure, the clinical features of which often resemble internal resorption ("pink tooth"). This article describes a case report of ICR and its management.
