Biocompatibility of several colloidal solutions containing nanoparticles on human gingival fibroblasts.

Background: There is little information concerning the biocompatibility of mouthwashes containing metal nanoparticles. This study was conducted to assess the biocompatibility of colloidal solutions containing zinc oxide (ZnO), copper oxide (CuO), titanium dioxide (TiO2), and silver (Ag) nanoparticles compared with chlorhexidine (CHX) in a culture of human gingival fibroblasts (HGFs).

Materials And Methods: This was an , experimental study.

Variations in Orofacial Clefts.

Objectives: The main objective of this study was to report the prevalence and other relative risk factors of oral clefts among newborn infants.

Methods: In this study, we reviewed the data regarding 234 infants with cleft anomalies as collected in questionnaires from 2004 to 2019 and demographic parameters were assessed.

Results: Cleft lip and palate was the most common anomaly (66.

The Effect of Immediate Versus Delayed Addition of the Nasal Stent to the Nasoalveolar Molding Plate on Nostrils Shape and Cleft Width in Infants With Unilateral Cleft Lip and Palate.

Objective: The main aim of this study was to evaluate the effect of immediate versus delayed addition of the nasal stent to the nasoalveolar molding plate on the nose shape and alveolar cleft area in unilateral cleft lip and palate infants.

Method: Twenty nonsyndromic newborn infants with unilateral cleft lip and palate were scanned 3 dimensionally using Proface software. In the experimental group, the nasal stent was added on the day the molding plate arrived, and in the control group when the alveolar gap reached 5 mm.
