Spectrophotometric evaluation of staining of different types of light-cure composite resins after exposure with different light-cure intensities: An study.

Context: Relation between the adequate intensity output of curing lights on color stability of composite resin is well accepted.

Aims: To investigate the effect of different light-curing intensities and its relation to color stability of different polymerized composite resin materials using the spectophotometric analysis.

Settings And Design: Comparative study done on composite resin discs.

Evaluation of YouTube Videos as a Source of Information About Oral Self-examination to Detect Oral Cancer and Precancerous Lesions.

Objectives: The aim of this study was to investigate quality, reliability, and comprehensiveness of YouTube videos about oral self-examination to detect oral cancer and precancerous lesions and to assess whether the source, duration, quality, reliability, and/or comprehensiveness of videos influence their visibility and popularity.

Materials And Methods: Videos on YouTube were searched using eight keywords similar to oral self-examination. The first 100 videos for each search term were included.

Microcomputed tomographic evaluation of shaping ability of two thermo mechanically treated single-file systems in severely curved roots.

Context: Canal shaping abilities such as canal transportation, centering ability, and preparation time are important and have to be considered before using any Nickel-Titanium file system.

Aim: This study aimed to evaluate and compare the amount of canal transportation, centering ability, and time required for the shaping of severely curved canals with WaveOne Gold (WOG) Primary Reciprocating file and One Curve (OC) Rotary file using the micro computed tomography (μCT).

Materials And Methods: Thirty intact mesial roots of extracted human mandibular first molars having severe curvature (25°-35°) were selected.

Shear bond strength of composite resin to resin-modified glass ionomer cement using 2-hydroxyethyl methacrylate-based and 2-hydroxyethyl methacrylate-free adhesive system.

Background: Sandwich technique combines the properties of both composite resin and glass ionomer cement to make the most of the physical and esthetic properties of each material. Bonding agents improve the wettability of GIC surface and improves the bond between composite resin and GIC. The aim of this study was to evaluate and compare shear bond strength of composite resin to resin modified glass ionomer cement using HEMA-based and HEMA-free adhesive systems.

Antimicrobial Efficacy of Different Endodontic Sealers against : An Study.

Objective: The aim of this study is to compare the antimicrobial efficacy of four different endodontic sealers against .

Material And Method: Four different endodontic sealers, namely, resin based (AH Plus), zinc oxide-eugenol based (Tubliseal), calcium hydroxide based (Sealapex), and mineral trioxide aggregate (MTA Fillapex) based were tested for their antimicrobial efficacy against using agar diffusion method. Four wells were made by the removal of agar at equidistant points and filled with freshly mixed respective root canal sealers and were inoculated with .

Efficacy of new irrigating solution on smear layer removal in apical third of root canal: A scanning electron microscope study.

Aims: The aim of this study is to evaluate and compare the smear layer removal efficacy of etidronic acid-based irrigating solution with others in the apical third of the root canal.

Materials And Methods: Forty human single-rooted mandibular premolar teeth were taken and decoronated to standardize the canal length. After biomechanical preparation, teeth were randomly divided into four groups ( = 10) and the final irrigation was carried out with tested irrigants.

Comparative evaluation of root canal disinfection by conventional method and laser: an in vivo study.

Objective: The aim of this study was to comparatively evaluate in vivo the disinfecting ability of conventional method and lasers in root canals.

Materials And Methods: Study criteria included 60 single rooted teeth, which were indicated for root canal therapy followed to dental caries and trauma with intact crowns. Such selected patients were randomly divided into 2 groups, namely, Group A (30 teeth) and Group B (30 teeth).

Osteosarcoma of the mandible mimicking an odontogenic abscess: a case report and review of the literature.

Unlabelled: Inflammatory lesions, like periapical/odontogenic abscesses, are by far the most common pathologic condition of the jaws. Radiographically, these lesions commonly manifest as widening of periodontal ligament space, discontinuity of lamina dura and ill-defined periapical radiolucency. There are some rare disorders which could cause similar radiographic changes in the jaw bone.

Effect of the presence of dental plaque on oral sugar clearance and salivary pH: an in vivo study.

Background: Fermentable carbohydrates and microorganisms in the plaque play a significant role in the pathogenesis of dental caries. Oral clearance of sugars and salivary pH is affected by the presence of plaque.

Aims And Objectives: This study was conducted to study the effect of the presence of plaque on the salivary clearance of sucrose and on salivary pH.

The effect of environmental pressure changes on the retentive strength of cements for orthodontic bands.

Objectives: The purpose of this study was to evaluate the effect of environmental pressure changes on the retentive strength of orthodontic bands cemented with conventional glass ionomer cement or resin-modified glass ionomer cement.

Materials And Methods: Stainless steel bands were cemented to 80 extracted first and second molars in two equal groups comprising conventional glass ionomer cement and resin-modified glass ionomer cement. Each group was randomly divided into two sub-groups of 20 samples each, one sub-group to act as a control, and the other to be used experimentally.
