Background and aim: Long-term denture tooth color stability for patients is an important criterion in choosing the types of dental materials to use as one main concerns treatment. Discoloration teeth may result patient dissatisfaction additional expense their replacement. In Yemen, khat (Catha Edulis) chewing habit affect acrylic teeth.

All samples stored distilled water (DW) at 37 °C 24 hours after which baseline colorimetric measurements recorded by colorimeter. immersed daily kept incubator 37°C 30 days. KH changed every hours. Colorimeter used change testing specimen 10, 20 days CIE L* a* b*. Then collected data analyzed using SPSS version 23. Results: results shows that there a significant (p<0.001). Also, interaction between found (p<0.05). time statistically revealed more significantly than DW Conclusions: homogenate (KH) causes discoloration increases with passage time. acceptable clinically except SND Vitapin has stable compared FX Peer Review History: Received: 12 February 2023; Revised: 13 March; Accepted: 25 April 2023, Available online: 15 May 2023 Academic Editor: Prof. Dr. Gorkem Dulger, Duzce University, Turkey, [email protected] Received file: Reviewer's Comments: Average review marks initial stage: 6.0/10 publication 7.0/10 Reviewers: Khaled A AL-Haddad,Orthodontics, Pedodontics Prevention Department Faculty Dentistry, Sana'a [email protected] Masoomeh S Ghahfarokhi, University Benin, Nigeria, [email protected]
