Overview

This study aims to evaluate and compare the impact of khat chewing on the color stability and patient satisfaction of multilayer zirconia and feldspathic veneered zirconia restorations. A split-mouth clinical trial design is utilized to assess color changes using a spectrophotometer and patient satisfaction via a structured questionnaire over the follow-up period.

Outcomes

Primary Outcomes

Color stability

Assessment of color change (delta E) of the restorations measured using a spectrophotometer.

Time frame: Baseline, 3 months, and 6 months

Secondary Outcomes

Patient Satisfaction

Evaluation of patient satisfaction with aesthetic appearance and overall restoration outcome measured using a standardized questionnaire or Visual Analog Scale (VAS).

Time frame: 6 months
