Aims and Scope

The Open Dentistry Journal is an Open Access online journal, which publishes research articles, reviews/mini-reviews, letters, case reports and guest edited single topic issues in all areas of dentistry and the oral cavity.


The journal encourages submissions related to the following fields of dentistry:

  • Restorative Dentistry
  • Management of Dental Disease
  • Periodontology
  • Dental Implants
  • Oral Pathology
  • Maxillofacial Surgery
  • Endodontology
  • Operative Dentistry
  • Fixed and Removable Prosthodontics
  • Dental Biomaterials Science
  • Oral Medicine
  • Clinical Trials
  • Translational Research


The Open Dentistry Journal, a peer-reviewed journal, is an important and reliable source of current information on important recent developments in the field. The emphasis will be on publishing quality papers rapidly and freely available to researchers worldwide.

Evaluation of Mechanical Properties and Antibacterial Activity of Nano Titania-Enriched Alkasite Restorative Material: An In Vitro Study

Neven S. Aref, Reham M. Abdallah

Background:

A biocompatible additive with the ability to establish antibacterial action for restorative materials without sacrificing their physical properties is always in demand. Nano titania (TiO2 nanoparticles) was shown to have antimicrobial action against a wide range of microorganisms. Alkasite is a modern esthetic restorative material that has outstanding properties; however, it is deficient in antibacterial activity.

Objective:

TiO2 nanoparticles (NPs) were included in alkasite, and both mechanical properties and antibacterial activity of the new formulations were assessed.

Materials and Methods:

Nano titania powder was coupled to alkasite powder in proportions of 3 and 5% (w/w). There were 105 specimens made in total. Evaluation parameters were compressive strength, surface microhardness, surface roughness, water sorption and solubility, and antibacterial activity. One and two-way ANOVA were used for the statistical analysis, followed by Tukey′s test (p<0.05).

Results:

Both ratios of nano titania, 3 and 5% (w/w), significantly increased compressive strength, antibacterial activity against different pathogens, and decreased water solubility of alkasite (p<0.05). Only 5% (w/w) nano titania-modified alkasite exhibited significant decrease in water sorption (p<0.05). Conversely, an insignificant increase in microhardness and surface roughness was observed with both ratios, 3 and 5% (w/w) of nano titania (p˃0.05).

Conclusion:

Nano titania seems to be a very promising complementary additive to the alkasite restorative material, capable of generating considerable antibacterial effectiveness while also enhancing certain mechanical properties.
