The influence of post‐curing protocols on the optical properties of provisional and long‐term 3D‐printable resin composites

European Journal of Oral Sciences, EarlyView.
Abstract This study determined the influence of post‐curing protocols on the color stability of provisional and long‐term 3D‐printable resin composites. Disc‐shaped specimens were fabricated from a provisional (Prov) and long‐term (Crown) 3D‐printable resin composites using a digital light processing printer.

Histogram‐Corrected Intraoral Photographs for Early Gingivitis Screening in Orthodontic Patients

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Objectives Gingivitis has a significant impact on periodontal health, both during and after orthodontic treatment. Early detection and management are essential for minimizing tissue damage. This study investigated an early gingivitis detection method using intraoral photographs (IOPs) taken before, at the midpoint (MO), and three‐quarters of ...
