Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

The effect of toothpaste and thermal aging on extrinsically stained additively manufactured zirconia: A comparative study on surface roughness and stain durability

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to compare the average surface roughness (Ra) and stain durability of extrinsically stained additively manufactured zirconia, after brushing with different toothpastes and thermal cycling, with those of subtractively manufactured zirconia and lithium disilicate.

Risk of Bias Evaluation of Cross‐Sectional Studies: Adaptation of the Newcastle‐Ottawa Scale

open access: yesJournal of Periodontal Research, EarlyView.
ABSTRACT Cross‐sectional studies are widely utilized in medical research to estimate prevalence and examine associations. As such, they can serve as a significant source of data for systematic reviews. However, specific considerations are necessary when evaluating the risk of bias (RoB) of cross‐sectional studies, as several potential biases can ...

Soft Tissue Substitutes: Current Biomaterials and Indications at Teeth and Implant Sites

open access: yesJournal of Periodontal Research, EarlyView.
This manuscript provides an updated overview of the current evidence on soft tissue graft substitutes for teeth and dental implants. When appropriately indicated, these biomaterials offer a reliable, less invasive alternative to autogenous grafts, effectively improving root coverage, keratinized mucosa width, and soft tissue thickness with reduced ...
