Objective: This study investigated the influence of photoinitiator types on degree of conversion (DC), rate of polymerization (RP), flexural strength (FS), flexural modulus (FM), and light transmittance (LT) of filled and unfilled light-curable resin cements through different thicknesses and shades of lithium disilicate ceramics.

Methods: Lithium disilicate ceramic discs (IPS Emax Press, background [0.0], 0.

Objective: To assess the influence of calcination process on the properties of minimally processed recycled 3Y-TZP, and to compare it with its commercial counterpart.

Methods: Non-milled 3Y-TZP waste was collected, fragmented and ball-milled to a granulometric < 5 µm. Half of the recycled powder was calcined at 900 °C.

Article Synopsis
  • The study investigates how the strength of temporary dental restorations is affected by thermal aging, focusing on different resin-based materials.
  • It involves testing 192 resin specimens made from various materials under thermal cycling conditions to assess their flexibility and strength.
  • Results show that the type of resin material and the thermal aging process significantly influence their strength, with Filtek Bulk-Fill performing better than J-Temp and Fuji Lining.

Objectives: This systematic review and meta-analysis (SRM) aimed to evaluate the efficacy of laser phototherapy (LPT) on the reduction in postoperative pain (PP) of endodontic origin after conventional/non-surgical reintervention of root canals.

Methods: This SRM was registered with PROSPERO (CRD42021243500) and followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Meta-analysis was conducted using R software with the "META" package, the mean difference (MD) measure of effect was calculated, and the fixed effect model was applied with a 95% confidence interval (CI).
