| الملخص: | <h3>Objectives</h3><p dir="ltr">To evaluate oral dryness and the taste sensation threshold (sweet, salt, sour, bitter) among khat chewers.</p><h3>Method</h3><p dir="ltr">This cross-sectional comparative study enrolled 140 healthy individuals divided into two groups: khat chewers (KC; n = 73), and non-chewers (NC; n = 67). Oral dryness was assessed using the Clinical Oral Dryness Score (CODS), while taste perception was assessed using the four primary tastes: sweet, salt, sour, bitter, along with the Total Taste Score (TTS), each prepared as seven chemical solutions representing seven concentrations. SPSS V. 26 was used for data analysis.</p><h3>Results</h3><p dir="ltr">Overall, KC revealed significantly higher overall CODS scores compared to NC (4.26±1.39 vs. 2.10±1.15; <i>P</i> < 0.001). The TTS was significantly lower in KC (16.52 ± 3.367) compared to NC (18.87 ± 3.592; <i>P</i> < 0.001), owing to revealing significantly lower mean taste sensation scores for sweet, salty, and bitter tastants, but not for sour taste. Up to 20.5% of KC had hypogeusia compared to only 4.5% of NC (<i>P</i> = 0.005). Multivariate analyses also revealed khat chewing as an independent determinant factor for oral dryness and hypogeusia.</p><h3>Conclusion</h3><p dir="ltr">Chronic khat chewing is associated with mouth dryness and taste impairment, gravely impacting on the patients’ quality of life.</p><h2>Other Information</h2><p dir="ltr">Published in: Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.oooo.2025.03.016" target="_blank">https://dx.doi.org/10.1016/j.oooo.2025.03.016</a></p> |
