Goal: The goal of this clinical trial is to evaluate the effectiveness of different oral hygiene methods (tooth brushing, tongue cleaning, and mouthwash use) in managing halitosis (bad breath) in adults. The main questions it aims to answer are: Do oral hygiene methods (tongue cleaning, chlorhexidine mouthwash, and coconut oil mouthwash) reduce the levels of volatile sulfur compounds (VSCs) in participants' breath? Do these methods improve self-reported and clinically assessed halitosis? Study Design: Researchers will compare three intervention groups: Group I: Tongue cleaning. Group II: Chlorhexidine mouthwash. Group III: Coconut oil mouthwash. After one week, Groups II and III will add tongue cleaning, and in the third week, Groups I and III will use chlorhexidine mouthwash to ensure equitable benefits. Participants will: Follow their assigned oral hygiene regimen daily for 2 weeks. Receive the halitosis assessments at baseline, 1 week, and 2 weeks post-intervention, including organoleptic testing and volatile sulfur compounds level measurements using the OralChroma device. Complete self-reported assessments of halitosis using a visual analog scale (VAS).

Reduction in Volatile Sulfur Compounds (VSCs) Levels
Measurement of VSC levels (hydrogen sulfide \[H2S\] and methyl mercaptan \[CH3SH\]) in participants' breath using the OralChroma device. Lower VSC levels indicate improved halitosis control.
Time frame: Baseline, 1 week post-intervention, and 2 weeks post-intervention.
Improvement in Organoleptic Test (OT) Scores
Clinical assessment of halitosis severity using the Organoleptic Test, where a trained examiner scores breath odor on a scale of 0 (no odor) to 5 (extremely strong odor). A reduction in OT scores indicates improvement in halitosis.
Time frame: Baseline, 1 week post-intervention, and 2 weeks post-intervention.
Improvement in Self-Reported Halitosis Severity
Participants' self-assessment of halitosis severity using a visual analog scale (VAS) ranging from 0 (no bad breath) to 100 (very severe bad breath). Lower scores indicate improved self-perceived halitosis.
Time frame: Baseline, 1 week post-intervention, and 2 weeks post-intervention.
