Evaluation of Permeable and Impermeable Membranes for Guided Bone Regeneration.

Background: The degree of biodegradation and the inflammatory response of membranes employed for guided bone regeneration directly impact the outcome of this technique. This study aimed to evaluate four different experimental versions of Poly (L-lactate-co-Trimethylene Carbonate) (PTMC) + Poly (L-lactate-co-glycolate) (PLGA) membranes, implanted in mouse subcutaneous tissue, compared to a commercially available membrane and a Sham group.

Methods: Sixty Balb-C mice were randomly divided into six experimental groups and subdivided into 1, 3, 6 and 12 weeks (n = 5 groups/period).

Analysis of the Viability and Morphology of Gingival Cells on Materials Used in Novel Prosthetic Components: Study.

Aim: The objective of this study was to evaluate the viability and morphology of human fibroblasts and keratinocytes cells, both grown on stainless steel (steel) (18Cr14Ni2.5Mo), and polyether-ether-ketone (PEEK) surfaces, hypothesizing the use of these surfaces as novel materials for prosthetic components.

Materials And Methods: Gingival human keratinocytes and gingival human fibroblasts lines were grown on discs made by steel ( = 36), PEEK ( = 36), and titanium (Ti) (Ti6A14V) ( = 36)-control.

Anaesthetic efficacy of 4% articaine compared with 2% mepivacaine: a randomized, double-blind, crossover clinical trial.

The aim of this study was to evaluate the clinical efficacy of 4% articaine (Ar4) compared to 2% mepivacaine (Me2), both in combination with 1:100,000 epinephrine, in a unique soft tissue model. This was a randomized, double-blind, crossover clinical trial. The anaesthetic was applied to the lower lip using a computerized local delivery system.
