Comparative Evaluation of Microleakage in Class II Composite Restorations Using Three Bulk-fill Composites with or without Resin-modified Glass Ionomer Cement Liner: A Stereomicroscopic Study.

Aim: To compare the microleakage of three bulk-fill composite resins with or without resin-modified glass ionomer cement (RMGIC) liner.

Materials And Methods: A total of 30 maxillary human 1st premolar teeth were selected. Two box preparations were made on the mesial and distal sides.

Comparative Evaluation of Efficacy of Four Different Materials in the Repair of Amalgam Restorations: An Study.

Aim: This study was aimed to compare the microleakage of amalgam restorations repaired with bonded amalgam, composite resin, ormocer, and glass ionomer restorative material.

Materials And Methods: Sixty extracted maxillary human premolars were prepared and restored with class I amalgam. A simulated defect was prepared that included the cavosurface margin on restorations, and the premolars were assigned to four treatment groups ( = 15): In group I, premolars were treated by bonded amalgam; in group II, premolars were repaired with composite resin; in group III, premolars were repaired by ormocer; and in group IV, premolars were repaired with glass ionomer restorative material.

A comparative clinical evaluation of accuracy of six apex locators with intraoral periapical radiograph in multirooted teeth: An study.

Aim: The purpose of this clinical study was to compare and clinically, to evaluate the accuracy of six apex locators with intra oral periapical (IOPA) radiograph in multirooted teeth.

Materials And Methods: A total of 90 multirooted teeth (maxillary and mandibular molars) with irreversible, infected or necrotic pulp tissue and completely formed roots were included in this study and were divided randomly into six groups (Root ZX II, Raypex 6, I-Root, Romiapex A-15, Sybron Endo Mini and Root ZX mini). The working length was determined using six different apex locators, and the accuracy of the apex locators was compared with IOPA radiographs, to be categorized as accurate, short, and long or beyond.

A Survey on Nickel Titanium Rotary Instruments and their Usage Techniques by Endodontists in India.

Introduction: The preference and usage of nickel titanium rotary instruments varies from individual to individual based on their technique, experience with the rotary systems and the clinical situation. Very limited information is available to explain the adoption of changing concepts with respect to nickel titanium rotary instruments pertaining to the endodontists in India.

Aim: The aim of this study was to conduct a questionnaire survey to acquire the knowledge concerning different NiTi rotary instruments and their usage techniques by endodontists in India.
