Study Arms (2)

Listerine Group

EXPERIMENTAL

Participants will receive Listerine mouthwash in unlabelled bottles once daily for 4 weeks.

Drug: Listerine Mouthwash Product

Chlorhexidine Group

ACTIVE COMPARATOR

Participants will receive chlorhexidine mouthwash in unlabelled bottles once daily for 4 weeks.

Drug: Chlorhexidine mouthwash

Interventions

Participants in this group will receive Listerine mouthwash containing essential oils (menthol, thymol, eucalyptol, and methyl salicylate). They will be instructed to rinse once daily with 10 ml of the solution for 30 seconds after brushing, over a period of 4 weeks. The mouthwash will be dispensed in unlabelled bottles to maintain blinding. Standard oral hygiene instructions will be given.

Also known as: Essential Oil Mouthwash
Listerine Group

Participants in this group will receive Chlorhexidine mouthwash at a concentration of 0.12%. They will be instructed to rinse once daily with 10 ml of the solution for 30 seconds after brushing, over a period of 4 weeks. The mouthwash will be dispensed in unlabelled bottles to maintain blinding. Standard oral hygiene instructions will be given.

Masking Details
Participants will be randomly assigned to either the Chlorhexidine or Listerine group using a block randomization method. To ensure blinding, both mouthwashes will be dispensed in identical, unlabelled bottles. Neither the participants, the care providers will be aware of the group allocation throughout the study period.
