Effect of a modified methyl methacrylate-p-styrene sulfonic acid copolymer-based gel desensitizer on dentin permeability and tubule occlusion in human dentin .

Background/purpose: Tubular occlusion is an effective method to treat dentin hypersensitivity. This study aimed to determine the effect of a modified methyl methacrylate-p-styrene sulfonic acid copolymer-based gel desensitizer on dentin permeability and tubule occlusion in extracted human premolars.

Materials And Methods: Hydraulic conductance (HC) measurement (n = 50) and scanning electron microscopy (SEM; n = 64) were performed.

Proliferative effect of cannabidiol in human gingival fibroblasts via the mitogen-activated extracellular signal-regulated kinase (MEK) 1/2.

Background And Objectives: Cannabidiol exerts its anti-inflammatory and anti-oxidant activities in various human cells. However, its proliferative effect has not been extrapolated to human gingival fibroblasts (HGFs). This study aimed to determine the proliferative and promigratory effects of cannabidiol in HGFs and to elucidate the signaling mechanism(s).

The use of the replica technique to record fluid emerging from exposed dentine.

The effect of pulpal cavity pressure on structures present on etched and unetched dentine was determined in 24 human premolars in vitro. The dentine was exposed in vivo. After extraction, the pulp was removed and the crown stored in 2.

Effect of triclosan on healing following non-surgical periodontal therapy in smokers.

Background: Tobacco smoking is an established risk factor for periodontitis, and is associated with periodontal attachment and tooth loss. Clinical studies have indicated that smoking may adversely affect and impede healing following periodontal therapy. Adjunctive antimicrobials, on the other hand, have been shown to enhance the effect of non-surgical periodontal therapy.

Microcirculation and micromorphology of healthy and inflamed gingivae.

Inflammation changes the microcirculatory and micromorphological dynamics of human gingiva. Laser Doppler flowmetry (LDF) and a replica technique for scanning electron microscopy (SEM) were used to examine the facial soft tissues of six maxillary anterior teeth, before and after treatment, in 12 patients exhibiting clinically healthy tissues and in 12 others with moderate gingivitis. All patients received oral hygiene instructions and scaling.
