Assessment of internal porosities for different placement techniques of bulk-fill resin-based composites: a micro-computed tomography study.

Objectives: The aim was to compare the porosity of different bulk-fill resin-based composites (RBCs) placement techniques to the conventional incremental technique using microcomputed tomography (μ-CT).

Material And Methods: Occlusal cavities were prepared on extracted human molars, divided into five groups based on the placement technique (n = 10/group). Techniques examined were Monoblock-two-step (SureFil SDR flow + Ceram.

The antiplaque/anticariogenic efficacy of Salvadora persica (Miswak) mouthrinse in comparison to that of chlorhexidine: a systematic review and meta-analysis.

Background: The plant Salvadora persica (miswak) has a long history of use in oral hygiene. Associations between the use of Salvadora persica and decreased oral bacteria numbers and plaque scores have been reported. This systematic review and meta-analysis assessed the ability of Salvadora persica mouthrinses to reduce plaque/cariogenic bacteria, in comparison to that of chlorhexidine and/or placebo rinses.
