Does Maras powder affect the nasal mucociliary clearence?

Area of Science:

• Respiratory Physiology
• Tobacco Product Research
• Otolaryngology

Background:

• Mucociliary clearance is a critical defense mechanism in the respiratory tract.
• Previous research has extensively documented the adverse effects of cigarette smoking on mucociliary clearance.
• The impact of smokeless tobacco products, such as Maras powder, on this physiological process remains understudied.

Purpose of the Study:

• To investigate the effect of Maras powder, a smokeless tobacco product, on nasal mucociliary clearance.
• To compare the effects of Maras powder use with cigarette smoking and non-tobacco use on mucociliary clearance.

Main Methods:

• Seventy-five adult males were divided into three groups: non-tobacco users, cigarette smokers, and Maras powder users (n=25 each).
• The saccharin test was employed to measure nasal mucociliary clearance time (MCCT) in seconds for all participants.
• Statistical analysis was performed to compare mean age and MCCT across the three groups.

Main Results:

• A statistically significant difference (p < 0.001) in MCCT was observed among the groups.
• Nasal mucociliary clearance time was prolonged in both cigarette smokers (796 ± 200 sec) and Maras powder users (644 ± 161 sec) compared to non-users (497 ± 108 sec).
• Cigarette smoking resulted in a greater prolongation of MCCT than Maras powder use.

Conclusions:

• Both cigarette smoking and Maras powder use negatively impact nasal mucociliary clearance.
• Nasal mucociliary clearance is more significantly impaired by cigarette smoking than by Maras powder use.
• These findings highlight the respiratory health risks associated with various forms of tobacco consumption.
