To analyze saliva and tongue coating pH in healthy patients with physiological halitosis before and after usage of 5 different types of mouthwash available in Malaysia. A quasiexperimental study was conducted among preclinical IIUM dental students aged 18 to 21 years old. Organoleptic evaluation was conducted by the operator to rank their organoleptic score followed by self-assessment by the participants. Saliva and tongue coating pH we measured respectively beforehand, immediately after and 30 minutes after rinsing with 5 different mouthwashes using a digital pH meter and pH strip indicator respectively; 100 participants were assigned into 5 groups, with 20 samples for each brand. Intraclass correlation coefficient between examiners ranged from 0.76-1.0. Data were analyzed statistically by repeated measure ANOVA test for each brand of mouthwash. Multivariate Analysis of Covariance (MANCOVA) + test was also used to statistically analyze different pH trends among the five brands of mouthwashes. Significant increase of salivary pH was observed after using MW2 (p<0.001) and MW4 (p=0.015). Significant reduction in salivary pH was observed when using MW5 (p=0.001). For tongue coating pH, significant reduction was observed after using MW2 (p<0.0010), MW3 (p=0.012), and MW4 (p=0.001). However, there was a significant increase in tongue coating pH after using MW5 (p=0.0125). Rinsing with mouthwashes MW2, MW3 and MW4 decreased tongue coating pH, which leads to reduced physiological halitosis.
