Optimization Of Post-Curing Conditions For 3d-Printed Dental Restorations: Mechanical And Color Stability Analysis, Mohammed Hammamy

ETDs from 2020-2029

Additive manufacturing has become increasingly utilized in dentistry for the fabrication of definitive restorations and provisional prostheses. However, the performance of 3D-printed materials is highly dependent on post-processing procedures, particularly post-curing, which influences the degree of polymerization and final material properties. The purpose of this study was to evaluate the effect of different post-curing protocols on the mechanical performance and color stability of a 3D-printed dental restorative material.Disc-shaped specimens were fabricated using a digital light processing (DLP) 3D printer and subjected to various post-curing conditions, including standard dental LED curing, nitrogen-assisted curing, glycerin immersion curing, Phrozen UV curing, VALO LED …

Toothbrush Resistance Of Resin-Based Stain And Glaze Materials Applied To 3d-Printed Denture Resins, Panisa Homyai

ETDs from 2020-2029

Background: Three-dimensionally printed (3D-printed) dentures are commonly fabricated using a single tooth-colored resin, after which surface stain and glaze coatings are applied to reproduce gingival coloration, enhance the esthetic appearance and improve clinical longevity of characterized prostheses. However, daily oral hygiene procedures such as toothbrushing degrade surface coatings, leading to discoloration, increased plaque retention, and deterioration of esthetic appearance. Objectives: To evaluate the effect of stain timing and glaze application on the surface gloss and roughness of a three-dimensionally printed denture resin before and after simulated toothbrushing Methods: 80 disc-shaped specimens (12 mm in diameter and 3 mm in thickness) …

Oral Cancer Numerical Index (Ocni): Development And Validation Of A Cytology-Based Risk Assessment For Oral Lesions, Michael P Mcrae, Nadarajah Vigneswaran, Alexander Ross Kerr, Spencer W Redding, Martin H Thornhill, Craig Murdoch, Paul M Speight, Rachelle Wolk, Kritika S Rajsri, Pooja Gaikwad, Nancy Ruel, Nicolaos J Christodoulides, John T Mcdevitt

Background/Objectives: Oral potentially malignant disorders (OPMDs) require accurate risk stratification to identify patients at the highest risk for severe oral epithelial dysplasia (OED) or oral squamous cell carcinoma (OSCC). We developed and internally validated the oral cancer numerical index (OCNI), a quantitative risk score derived from clinical features and deep learning-based brush cytology measurements.

Methods: This retrospective model development and internal validation study was conducted using data from the multicenter Grand Opportunity study. Prospectively recruited subjects with OPMD with complete data were divided at the subject level into a training set (n = 384) and a holdout test set …
