Accuracy Of Intraoral Scanners With Different Total Occlusal Convergence Angles: An In-Vitro Study, Brittany M. Pang

Loma Linda University Electronic Theses, Dissertations & Projects

Digital intraoral imaging has become more utilized in contemporary dental practice. This is performed using an intraoral scanner and it can be used as an alternative to making conventional impressions when indicated. This technology has many advantages, such as decreasing the number of appointments by eliminating traditional techniques, along with a reduction of laboratory time and improved patient comfort. The accuracy of intraoral scanners is currently being assessed in various aspects. To our knowledge, no study has yet addressed the accuracy of intraoral scanners in regards to total occlusal convergence (TOC) of complete coverage of anterior and posterior preparations in …

Comparison Of Antimicrobial Agents Ozonated Olive Oil And Chlorhexidine Gluconate - An In Vitro Study, Amelia David

Loma Linda University Electronic Theses, Dissertations & Projects

Aim: This study was aimed to compare the antibacterial effect of a commercially available OzOO with CHX 0.12% oral rinse solution against periodontal pathogens F. alocis, Aa, S. mitis, and S. mutans using a disk diffusion method.

Materials and Methods:

The antimicrobial agents OzOO and 0.12% CHX were impregnated onto sterile discs and placed onto bacterial cultures of F.alocis, Aa, S.mutans, and S.mitis to evaluate their antimicrobial activity by the disk diffusion susceptibility method. The bacterial growth inhibition zone surrounding each disc was measured in millimeters of diameter with calipers to assess the antimicrobial activity of each agent. …
