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.

Comparative evaluation of the remineralizing potential of different calcium and fluoride-based delivery systems on artificially demineralized enamel surface; an study.

Background: Enamel is the hardest and vastly mineralized structure of the human body. Inorganic salts make up the majority of it. Water and ions pass right through the enamel.

The effect of pressure changes during simulated diving on the shear bond strength of orthodontic brackets.

Introduction: This study investigated the effect of pressure variations to which divers are subjected on shear bond strength of orthodontic brackets bonded to teeth with resin modified glass ionomer cement (RMGIC) or composite resin.

Methods: Eighty extracted premolars were randomly divided into two groups. Group 1: orthodontic brackets were bonded with RMGIC.

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.
